    OBJECTIVES: Subglottic cancer is a rare malignancy for which limited data on its epidemiology, prognosis, recurrence, and laryngeal preservation are available. This multicenter, retrospective study aimed to elucidate the treatment outcomes of subglottic cancer compared with glottic and supraglottic cancers. MATERIAL AND METHODS: Sixty-six patients with subglottic cancer were identified among 1763 patients with laryngeal cancer treated with curative-intent surgery or (chemo)radiotherapy at 13 hospitals in northern Japan. Patients' characteristics, treatment modalities, recurrence patterns, and prognosis, including disease-free survival (DFS), overall survival (OS), disease-specific survival (DSS), and laryngeal-preservation survival (LPS), were compared across the three primary tumor subsites. Outcomes of subglottic cancer were further analyzed according to initial treatment. RESULTS: Compared with glottic and supraglottic cancers, subglottic cancer presented with more advanced T status, higher rates of total laryngectomy and recurrence, and poorer DFS, OS, DSS, and LPS. Analysis by stage indicated that subglottic cancer tended to show poorer DFS in stage III-IV cases. In subglottic cancer, (chemo)radiotherapy was effective for T1-2 disease, whereas T3-4 cases had a high local recurrence rate. Total laryngectomy provided good local control in T3-4 cases, but it was frequently followed by nodal recurrence and distant metastasis. CONCLUSION: Subglottic cancer demonstrated a more locally advanced presentation and poorer prognosis than other laryngeal subsites, a trend also observed in stage III-IV disease. Though initial surgery provided good local control in advanced subglottic cancer, it was associated with high rates of nodal recurrence and distant metastasis.

    PURPOSE: Acoustic analysis is an objective and quantitative method in diagnosing speech disorders and evaluating treatment efficacy. Although many reports have used acoustic analysis for oral cancer patients, few studies have focused on the extent of tongue resection. The aim of this study was to evaluate the usefulness of acoustic analysis in the assessment of postoperative speech impairment in oral cancer patients. METHODS: Postoperative speech data as well as Speech Handicap Index (SHI) and 5-point speech intelligibility scale were collected from 65 patients including 31 cases of oral cancer resection without glossectomy, 18 cases of partial glossectomy, and 16 cases of subtotal glossectomy. Speech data were acoustically analyzed by triangular vowel space area, vowel articulation index (VAI), first (F1) and second (F2) formant slopes, and compared according to the extent of tongue resection. RESULTS: The frequency of speech impairment assessed by SHI and 5-point speech intelligibility scale was differed according to the extent of tongue resection. As acoustic analysis, VAI and F1 slope in cases of subtotal glossectomy were significantly smaller than those in cases of partial glossectomy. F2 slope in cases of subtotal glossectomy was significantly smaller than those in the other cases. CONCLUSION: Acoustic analysis was potentially useful as an objective speech assessment for the patients who underwent oral cancer surgery.

    BACKGROUND: Treatment of unresectable salivary gland cancers is challenging. This multicenter, retrospective study aimed to evaluate the treatment outcomes of definitive radiotherapy, with or without chemotherapy, for locally advanced, unresectable, salivary gland cancers. METHODS: A total of 27 patients with unresectable salivary gland cancers who underwent concurrent chemoradiotherapy or radiotherapy with curative intent between 2012 and 2022 at 13 hospitals in northern Japan were included in this study. Overall survival (OS) and progression-free survival (PFS) were assessed, and factors affecting OS and PFS were identified through univariate and multivariate Cox regression analyses. The variables evaluated included age, sex, primary site, histological type, clinical T and N status, clinical stage, treatment type, and radiation type. RESULTS: Seven patients received concurrent chemoradiotherapy, and 20 patients received radiotherapy (6 photon, 11 proton, 3 heavy ion). With a median follow-up period of 28 months, the three-year OS and PFS rates for the 27 patients were 54.4% and 27.8%, respectively. Patients who received concurrent chemoradiotherapy had better PFS than those who received radiotherapy alone (HR 0.16, 95% CI 0.03-0.81, P = .026). CONCLUSIONS: Definitive radiotherapy for locally advanced, unresectable, salivary gland cancers resulted in relatively good outcomes. Concurrent chemoradiotherapy was associated with better PFS than radiotherapy.

    BACKGROUND: Immune checkpoint inhibitors (ICIs) improve outcomes in recurrent/metastatic head and neck squamous cell carcinoma (R/M HNSCC). However, some patients remain unresponsive to treatment, necessitating further investigation into optimal therapeutic strategies and prognostic biomarkers. This study aimed to evaluate the efficacy of various therapies and identify factors influencing overall survival (OS) in these patients. METHODS: We retrospectively analyzed 606 patients (517 men, 89 women; median age 68 years) treated at 13 head and neck cancer specialty facilities in Japan between January 2018 and December 2022. Associations between OS and variables, including age, sex, primary site, Eastern Cooperative Oncology Group performance status, estimated glomerular filtration rate, therapeutic target lesion, history of drug use in systemic chemotherapy, number of treatment lines, nondrug treatments, de novo metastasis, programmed death-ligand 1 combined positive score, and platinum resistance were statistically examined. RESULTS: Median OS was 14.2 months, and median progression-free survival was 5.0 months. Multivariate analysis identified poor OS in patients with oral cavity tumors and performance status 2-3, whereas ICI therapy and nondrug salvage interventions were associated with improved OS. ICI/non-ICI subgroup analysis revealed that ICI may have a limited effect on oral cancer. Additionally, our results indicated that a history of platinum therapy for R/M HNSCC may not affect the therapeutic efficacy of ICIs. CONCLUSION: For patients with R/M HNSCC, further OS improvement may be achieved using ICIs or aggressive nondrug salvage therapy and by considering the use of chemotherapy other than ICI for patients with oral cancer or poor PS.

    OBJECTIVE: Sensorineural hearing loss (SNHL) is one of the most important adverse events of concurrent chemoradiotherapy (CCRT) with high-dose cisplatin for locally advanced head and neck squamous cell carcinoma (HNSCC). This retrospective study aimed to elucidate the effects of nutritional status and trace elements on the development of SNHL. METHODS: A retrospective review of 211 ears from 109 patients with HNSCC who underwent CCRT with high-dose cisplatin was performed. SNHL of each ear was classified according to Common Terminology Criteria for Adverse Events (CTCAE) version 5.0, and possible contributing factors were evaluated by univariate and multivariate analyses. Age, sex, primary site, clinical stage, treatment intent, smoking and drinking habits, history of hypertension, diabetes mellitus, body mass index, serum albumin, trace elements (Fe, Zn, Cu, Se), pretreatment average hearing level at 2-8 kHz, weight loss rate, cumulative cisplatin dose, and inner ear radiation dose were the variables evaluated. RESULTS: Ordinal logistic regression analysis showed that increased age, better pretreatment average hearing level at 2-8 kHz, and cumulative cisplatin dose were independent factors associated with the development of SNHL. CONCLUSION: Nutritional status and trace elements were not associated with the development of SNHL caused by CCRT with high-dose cisplatin.

    OBJECTIVES: Salivary gland cancer is a rare disease composed of more than 20 histological types with different grades of malignancy. The aim of this multicenter, retrospective study was to identify the most important predictors affecting recurrence and survival after surgery. MATERIAL AND METHODS: A total of 543 patients with salivary gland cancers that underwent curative surgery between 2012 and 2022 in 13 institutions in northern Japan were evaluated in this study. Predictors affecting recurrence and survival were identified by univariate and multivariate Cox regression analyses. Age, sex, primary site, histological type, pathological T status, surgical margin, lymph node metastasis, extranodal extension, and postoperative radiotherapy were the variables evaluated. RESULTS: Multivariate Cox regression analysis showed that increasing age, submandibular cancer, pathological T status 3 or 4, positive surgical margin, and lymph node metastasis, especially with extranodal extension, were independent risk factors for both recurrence and survival. Sublingual cancer was an independent risk factor for recurrence. Postoperative radiotherapy was associated with a lower risk of recurrence and a good prognosis, and adenoid cystic carcinoma was associated with a good prognosis. CONCLUSION: Lymph node metastasis with extranodal extension was the most important prognostic factor affecting both recurrence and survival after surgery, adenoid cystic carcinoma was associated with a good prognosis, and postoperative radiotherapy was associated with a lower risk of recurrence and a good prognosis.

    Previous studies of the treatment of elderly head and neck cancer (HNC) patients were very limited and sometimes controversial. Although conclusions differ across various reports, it is often concluded that advanced chronological age does not directly affect prognosis, but that comorbidities and declines in physical and cognitive functions promote the occurrence of adverse events, especially with surgical treatment. Geriatric assessment (GA) and its screening tools are keys to help us understand overall health status and problems, predict life expectancy and treatment tolerance, and to influence treatment choices and interventions to improve treatment compliance. In addition, personal beliefs and values play a large role in determining policies for HNC treatment for elderly patients, and a multidisciplinary approach is important to support this. In this review, past research on HNC in older adults is presented, and the current evidence is explained, focusing on the management of elderly HNC patients, with an emphasis on the existing reports on each treatment stage and modality, especially the surgical procedures.

    INTRODUCTION: Compared to other cancers, research on bloodstream infection in head and neck cancer is scarce, lacking comparative studies on persistent versus transient bacteremia outcomes. METHODS: This retrospective survey examined patients with head and neck cancer undergoing blood culture at our center from June 2009 to May 2023. Blood culture-positive cases suspected of infection were divided into persistent bacteremia and transient bacteremia groups. We investigated their clinical, epidemiological, and microbiological features, including risk factors for persistent bacteremia and mortality. The primary outcome was 90-day mortality. RESULTS: In this 97-patient cohort, 14 (14%) cases were assigned to the persistent bacteremia group. Catheter-related bloodstream infections were the leading cause of infection in both groups, consistently contributing to a high proportion of overall bloodstream infections. The mortality rate was generally higher in the persistent bacteremia group than in the transient bacteremia group (odds ratio [OR], 2.6; 95% confidence interval [CI], 0.6-11.1), particularly in the non-clearance subgroup (OR, 9; 95% CI, 0.5-155.2). Pyogenic spondylitis was a key risk factor for persistent bacteremia, while hypoalbuminemia increased mortality. CONCLUSION: In patients with bacteremia and head and neck cancer, persistent bacteremia was associated with higher mortality than was transient bacteremia. Adittionally, bacteremia clearance in persistent bacteremia is thus crucial for prognostic improvement.

    Salivary gland cancers (SGCs) are heterogeneous tumors, and precision oncology represents a promising therapeutic approach; however, its impact on SGCs remains obscure. This study aimed to establish a translational model for testing molecular-targeted therapies by combining patient-derived organoids and genomic analyses of SGCs. We enrolled 29 patients, including 24 with SGCs and 5 with benign tumors. Resected tumors were subjected to organoid and monolayer cultures, as well as whole-exome sequencing. Organoid and monolayer cultures of SGCs were successfully established in 70.8% and 62.5% of cases, respectively. Organoids retained most histopathological and genetic profiles of their original tumors. In contrast, 40% of the monolayer-cultured cells did not harbor somatic mutations of their original tumors. The efficacy of molecular-targeted drugs tested on organoids depended on their oncogenic features. Organoids recapitulated the primary tumors and were useful for testing genotype-oriented molecular targeted therapy, which is valuable for precision medicine in patients with SGCs.

    Ototoxicity is a dose-limiting adverse event for concurrent chemoradiotherapy (CCRT) with high-dose cisplatin for locally advanced head and neck squamous cell carcinoma (HNSCC). Both irradiation to the Eustachian tube (ET) and weight loss are risk factors for patulous ET. The aim of this prospective, observational study was to elucidate the incidences of patulous ET conditions before and after CCRT in HNSCC patients by means of ET function tests. This prospective, observational study was conducted in 27 HNSCC patients who received CCRT with high-dose cisplatin, and ET function tests (sonotubometry and tubo-tympano-aerodynamic graphy) were performed before and 3 months after CCRT. Factors potentially affecting the incidence of patulous ET conditions after CCRT were evaluated. Of the 54 ears from 27 patients investigated, patulous ET conditions were observed in 12 ears (22.2%) from 9 patients (33.3%) before CCRT and 15 ears (27.8%) from 11 patients (40.7%) at 3 months after CCRT. Only patulous ET conditions before CCRT in each ear were significantly associated with patulous ET conditions after CCRT (p = 0.010). This is the first report to describe the incidences of patulous ET conditions before and after CCRT in HNSCC patients. HNSCC patients are potentially at higher risk of patulous ET.

    OBJECTIVE: This study aimed to investigate the distribution of human papillomavirus 16 (HPV16) variants that contribute to the development of HPV-related oropharyngeal carcinoma (HPV-OPC) in the Japanese population and to evaluate genetic variations in the sequence encoding the L1 antigen region of the viral outer shell that is targeted by existing vaccines and is relevant for designing a prevention strategy to combat the exponential increase in HPV-OPC cases in Japan. METHODS: Seventy Japanese HPV-OPC patients treated at Tohoku University Hospital were included in the study. DNA was extracted from formalin-fixed, paraffin-embedded tissue samples. Polymerase chain reaction and direct nucleotide sequencing were performed to determine the nucleotide polymorphisms necessary for the classification of HPV16 variants and to assess genetic diversity in the HPV16 L1 antigen region, including the BC, DE, EF, FG, and HI loops. RESULTS: The most common variant of HPV16 was the A4 sublineage (88.6%), conventionally called the Asian type, followed by the A1/2/3 (10.0%) sublineage, classified as the European type. The only nonsynonymous substitution detected in the L1 antigen loop region was p.N181T in the EF loop, which was found in 28/70 (40%) cases. In contrast, no nonsynonymous substitutions were observed in the DE, FG, and HI loops, which are particularly important regions in the antigen loop targeted by existing HPV vaccines. CONCLUSION: The most common HPV16 variant in Japanese HPV-OPC patients was the A4 subtype. The L1 antigen region is highly conserved, suggesting sufficient efficacy of existing HPV vaccines. These findings provide important information that will aid in the design of an HPV16 infection control strategy using existing HPV vaccines to prevent the spread of HPV-OPC in Japan.

    OBJECTIVE: Head and neck surgeries may cause changes in the nasal airflow, and radiotherapy irreversibly damages paranasal sinus epithelial cells. Some chemotherapeutic drugs have been reported to negatively affect airway ciliary activity in mice, and chronic rhinosinusitis could be an adverse effect of head and neck cancer (HNC) treatment. To evaluate whether HNC treatment is a risk factor for developing sinonasal mucosal thickening that may reflect paranasal sinus inflammation, we compared pre- and post-treatment paranasal sinus computed tomography (CT) images of patients treated for HNC at a single university hospital. METHODS: The patients who received curative treatment for HNC (oral, pharyngeal, and laryngeal cancers) and started receiving first-line therapy between January 2015 and December 2019 were included. Data on age, sex, primary lesion, clinical stage, treatment, smoking history, drinking history, comorbidities (diabetes and chronic lung disease), and pre- and post-treatment (three months and one year after the final treatment) paranasal sinus CT images were analyzed from medical records. Pre- and post-treatment paranasal sinus CT images were scored using the Lund-Mackay (LM) staging system. RESULTS: In total, 245 patients participated in this study. Three months after the final treatment, 80.4% of patients had no change in their total LM scores (p=0.621). Almost 80% of patients who underwent total laryngectomy also had no change in their total LM scores (p=0.833). One-third of patients with nasopharyngeal cancer (NPC) had worse LM scores after treatment (5/15), although no significant difference was observed (p=0.171). None of the various factors collected were significantly related to changes in LM scores three months after the completion of treatment. One year after the final treatment, 211 patients were included and no significant changes in the pre-and post-LM scores were observed in the same analyses, while changes in LM scores were significantly different between T categories (T1-2 vs. T3-4) (p=0.020). CONCLUSION: We found no significant changes in the LM scores after HNC treatment in all the patients, which implies that HNC treatment may not be an apparent risk factor for sinonasal mucosal inflammation.

    This retrospective study aims to describe the clinico-epidemiological characteristics of bloodstream infections (BSIs) and the risk factors in patients with head and neck cancer (n = 227) treated at the Department of Otolaryngology, Head and Neck Surgery, Tohoku University Hospital between April 2011 and March 2021. Overall, 23.3% of blood cultures were positive. In the culture-positive group, catheter-related bloodstream infections (CRBSIs) were the most common (38.8%), followed by respiratory tract infections (19.4%), and catheter-associated urinary tract infections (6.0%). Methicillin-resistant Staphylococcus aureus (26.9%), Staphylococcus epidermidis (17.9%), and Pseudomonas aeruginosa (10.4%) infections were common. The most frequent treatment for head and neck cancer was surgery (23.9%), followed by treatment interval or palliative care (19.4%), and single radiotherapy (13.4%). The 30-day mortality rate was significantly higher in the BSI than in the non-BSI group (10.4% vs. 1.8%, respectively). CRBSIs are the most frequent source of BSIs in patients with head and neck cancer. In conclusion, central venous catheters or port insertion should be used for a short period to prevent CRBSIs. The risk of developing BSI should be considered in patients with pneumonia. Understanding the epidemiology of BSIs is crucial for diagnosing, preventing, and controlling infections in patients with head and neck cancer.

    BACKGROUND: The palatal augmentation prosthesis (PAP) is an intraoral prosthesis used in the treatment of dysphagia. AIM: The objective of the study is to examine the effect of PAP using tongue pressure and the Videofluoroscopic Dysphagia Scale (VDS) to understand the precise mechanism for improvement in swallowing function with PAP for oral cancer at retrospective survey. METHODS AND RESULTS: Fifteen patients were provided PAPs. Tongue pressure and VDS were evaluated with and without PAP. After intervention with PAP, tongue pressure significantly increased as compared to when without PAP (p < .05). The total mean VDS score with PAP was found to have significantly improved (p < .05). The mean VDS score of the oral phase also significantly improved with the PAP compared to without the PAP group (p < .05). Significant differences (p < .01) were found in each category, such as tongue to palate contact and pyriform sinus residue. CONCLUSION: PAP can improve tongue pressure, tongue to palate contact, and pyriform sinus residue.

    OBJECTIVE: Partial maxillectomy and postoperative radiotherapy are both risk factors associated with trismus. This retrospective study aimed to evaluate the incidence and severity of trismus in patients following partial maxillectomy with or without postoperative radiotherapy and to compare free flap reconstruction and prosthetic obturation. METHODS: A retrospective review of 40 oral cancer patients who underwent partial maxillectomy with or without postoperative radiotherapy was performed. Maximum interincisal distance recorded at least 6 months after surgery was classified according to a revised subjective-objective management-analytical (SOMA) scale and compared between the free flap reconstruction group (n = 12) and the prosthetic obturation group (n = 28). RESULTS: Trismus was observed in 16/40 (40%) patients, and severe trismus was observed in 4/40 (10%) patients. Although no significant difference in trismus grade was observed between the free flap reconstruction and prosthetic obturation groups, both severe trismus and radiation-induced osteonecrosis were only seen in the prosthetic obturation group with postoperative radiotherapy. CONCLUSION: Free flap reconstruction was preferable to prosthetic obturation to avoid severe trismus and radiation-induced osteonecrosis in patients who underwent both partial maxillectomy and postoperative radiotherapy.

    PURPOSE: Radical surgery with free flap reconstruction for locally advanced head and neck cancer (HNC) is quite challenging for older adults. This retrospective study aimed to elucidate the usefulness of the geriatric-8 (G8) screening tool for predicting postoperative complications in older adults with HNC. METHODS: A retrospective review of 37 older adults with HNC who underwent radical surgery with free flap reconstruction and were assessed by the G8 screening tool was performed. Postoperative complications during hospitalization were classified according to the Clavien-Dindo classification, and possible contributing factors, including the G8 score, for major and minor complications were subjected to univariate and multivariate analyses. RESULTS: The appropriate G8 cut-off value for both major and minor complications was 12 (area under the curve 0.56 and 0.55, respectively). Multivariate logistic regression analysis showed that both smoking and lower G8 score (≤ 12) were independently associated with the severity of complications (p = 0.043, p = 0.034, respectively). CONCLUSIONS: The G8 was a possible predictor of major and minor complications in older adults with HNC who underwent radical surgery with free flap reconstruction.

    There are no established guidelines for managing older patients with head and neck cancer. Most clinical trials that define current standard therapy included few elderly patients. On the other hand, there is great variability in patients' comorbidities, physical functions, cognitive function, familial and financial background and values. The key point appears to be appropriate geriatric assessment, clarifying the patients' outcomes and a multidisciplinary team approach, including the treatment decision-making policy. Although these processes should be scientific in nature, the evidence for the treatment of elderly head and neck patients is very limited. This review summarizes the evidence available regarding the management of geriatric assessment, each treatment modality and the multidisciplinary team approach for older patients with head and neck cancers.

    OBJECTIVE: The higher sensitivity of the new-generation positron emission tomography/computed tomography (PET/CT) with silicon photomultiplier (SiPM) may increase false-positive rates in detecting metastatic lymph nodes (LNs). This study aimed to clarify the usefulness of the SiPM PET scanner in diagnosing LN metastasis of oral squamous cell carcinoma (SCC). METHODS: We retrospectively reviewed consecutive F-18 fluorodeoxyglucose PET/CT images of 39 SCC patients using SiPM PET and 31 SCC patients using non-SiPM PET. We measured the maximum standardized uptake value (SUVmax) of the LNs on PET images and maximum short-axis diameter on transverse CT images. RESULTS: The sensitivity and specificity of SiPM PET were 86.2% and 95.6%, respectively (cut-off SUVmax, 4.6). The area under the curve (AUC) of SiPM PET (0.977; 95% confidence interval [CI], 0.958-0.995) was significantly higher than that of non-SiPM PET (0.825; 95% CI 0.717-0.934) (P < 0.01). In a size-limited analysis of diameter, the AUC of SiPM PET (≥ 0.96 for all diameters) was significantly higher than that of non-SiPM PET (tended to decrease as the LN diameter decreased) for the diagnosis of LN metastasis by SUVmax. CONCLUSION: SiPM PET had higher diagnostic accuracy for LN metastasis of oral SCC than non-SiPM PET, even for small LN metastasis without increasing false-positives.

    OBJECTIVE: Computer-aided design and computer-aided manufacturing (CAD/CAM) techniques are increasingly applied to mandibular reconstruction, but the superiority of this method in oral food intake has not been well established. Considering the extent of mandibular defects, this retrospective study was aimed to clarify the impact of CAD/CAM mandibular reconstruction on chewing and swallowing function after surgery for locally advanced oral cancer. MATERIALS AND METHODS: We performed a retrospective review of 50 patients who had undergone segmental mandibulectomy with free flap reconstruction for locally advanced oral cancer. The patients' Functional Oral Intake Scale scores were measured at 3 months after surgery, and possible contributing factors including CAD/CAM mandibular reconstruction and the extent of mandibular defects for oral food intake were subjected to univariate analysis and multivariate logistic regression analysis. RESULTS: Multivariate logistic regression analysis showed that CAD/CAM mandibular reconstruction was independently associated with good oral intake, whereas both anterior or extensive mandibular resection and glossectomy were also independently associated with poor oral intake after surgery. CONCLUSION: The present study showed the positive impact of CAD/CAM mandibular reconstruction on chewing and swallowing function after surgery for locally advanced oral cancer for the first time.

    OBJECTIVE: Concurrent chemoradiotherapy (CCRT) with three-weekly high-dose cisplatin (100 mg/m2) is a standard treatment for locally advanced head and neck squamous cell carcinoma (HNSCC), but compliance with cisplatin is often poor due to various adverse events. The aim of this prospective, observational study was to determine the predictors of achievement of full-dose cisplatin. METHODS: A prospective, observational study was conducted involving 60 patients who received CCRT with three-weekly high-dose cisplatin (100 mg/m2) for locally advanced HNSCC. Possible predictors affecting compliance with cisplatin were subjected to univariate and multivariate logistic regression analyses. Age, sex, primary site, clinical stage, treatment intent, history of hypertension, diabetes mellitus, smoking and drinking habits, body mass index, creatinine clearance, serum albumin, controlling nutrition status, trace elements (Fe, Zn, Cu, Se), acute kidney injury, white blood cell count decrease, neutrophilia, and weight loss were the variables evaluated. RESULTS: Twenty-seven patients achieved full-dose cisplatin (300 mg/m2), and the other 33 patients did not. Multivariate logistic regression analysis showed that both mild renal dysfunction and selenium deficiency before treatment independently had negative impacts on achievement of full-dose cisplatin. CONCLUSIONS: As well as renal function, selenium deficiency is a potential therapeutic target for CCRT with high-dose cisplatin in HNSCC patients.

    OBJECTIVES: To clarify the usefulness of geriatric assessment screening tools for predicting prognosis and complications in older adults with head and neck cancer (HNC). MATERIAL AND METHODS: The geriatric-8 (G8) screening tool was administered to 78 older adults with HNC at their first visit to the hospital before any treatments. The ability of the G8 to predict survival was evaluated by receiver operating characteristic (ROC) curve analysis and determining the cut-off value using Youden's Index. The G8 and other factors related to prognosis (age, performance status (PS), Charlson comorbidity index, number of oral medicines (polypharmacy), the controlling nutritional status (CONUT) score for biological nutrition status, and treatment intent (curative or palliative)) were validated by Cox proportional hazards regression analysis. The survival analysis was validated in a propensity score-weighting cohort to correct for confounding factors. Correlations between these factors and complications were examined using Fishers exact test. RESULTS: The G8 cut-off value for overall survival was 10.5 (area under the curve (AUC) 0.69; 95% confidence interval (CI) 0.56-0.82). In the propensity score-weighted cohort, on Cox proportional hazards regression analysis, the hazard ratio of an abnormal G8 (<11) was 3.70 [1.59-8.61 (p = 0.002)], and the hazard ratio of PS-abnormal (≥2) was 0.85 [0.09-7.60 (p = 0.88)]. Thirty-day mortality and all-complication rates were significantly higher in the G8-abnormal group. Neither major complications nor transfer to other institutions was correlated with an abnormal G8. CONCLUSION: The G8 was a strong prognostic factor and a possible predictor of complications in older adults with HNC.

    BACKGROUND: Pneumonia is a common cause of illness and death of the elderly in Japan. Its prevalence is escalating globally with the aging of population. To describe the latest trends in pneumonia hospitalizations, especially aspiration pneumonia (AP) cases, we assessed the clinical records of pneumonia patients admitted to core acute care hospitals in Miyagi prefecture, Japan. METHODS: A retrospective multi-institutional joint research was conducted for hospitalized pneumonia patients aged ≥20 years from January 2019 to December 2019. Clinical data of patients were collected from the medical records of eight acute care hospitals. RESULTS: Out of the 1,800 patients included in this study, 79% of the hospitalized pneumonia patients were aged above 70 years. The most common age group was in the 80s. The ratio of AP to total pneumonia cases increased with age, and 692 out of 1,800 patients had AP. In univariate analysis, these patients had significantly older ages, lower body mass index (BMI), a lower ratio of normal diet intake and homestay before hospitalization, along with more AP recurrences and comorbidities. During hospitalization, AP patients had extended fasting periods, more swallowing assessments and interventions, longer hospitalization, and higher in-hospital mortality rate than non-AP patients. A total of 7% and 2% AP patients underwent video endoscopy and video fluorography respectively. In multivariate analysis, lower BMI, lower C-reactive protein, a lower ratio of homestay before hospitalization, a higher complication rate of cerebrovascular disease, dementia, and neuromuscular disease were noted as a characteristic of AP patients. Swallowing interventions were performed for 51% of the AP patients who had been hospitalized for more than two weeks. In univariate analysis, swallowing intervention improved in-hospital mortality. Lower AP recurrence before hospitalization and a lower ratio of homestay before hospitalization were indicated as characteristics of AP patients of the swallowing intervention group from multivariate analysis. Change in dietary pattern from normal to modified diet was observed more frequently in the swallowing intervention group. CONCLUSION: AP accounts for 38.4% of all pneumonia cases in acute care hospitals in Northern Japan. The use of swallowing evaluations and interventions, which may reduce the risk of dysphagia and may associate with lowering mortality in AP patients, is still not widespread.

    PURPOSE: To clarify the correlations among symptoms, swallowing functions, and ingestion status and to validate a method of swallowing evaluation during chemoradiotherapy (CRT) for head and neck cancer. METHODS: Oropharyngeal and hypopharyngeal cancer patients who were to receive definitive CRT as initial treatment were included in this prospective, single-center, observational study. The Functional Oral Intake Scale (FOIS) for ingestion status and grades of symptoms (dryness, dysgeusia, mucositis, and the analgesic ladder); the Yale Pharyngeal Residue Severity Rating Scale on fiberoptic endoscopic evaluation of swallowing (FEES) and the Penetration-Aspiration Scale (PAS) on videofluoroscopic (VF) evaluation for swallowing functions; and the 10-item Eating Assessment Tool (EAT-10) questionnaire were assessed at 5 time points unless the participant refused. The FEES and VF evaluation findings at each point were also compared. RESULTS: There were 38 participants. Dysgeusia, mucositis, and pain grade, as well as the FOIS score, were the worst at 70 Gy and then improved after treatment. The improvements of pharyngeal residue and the PAS after treatment were limited. The EAT-10 and the pain ladder were highly correlated with the FOIS changes at many time points. The VF evaluation rate dropped after 40 Gy, whereas the FEES rate remained high. There were good correlations between pharyngeal residue and the PAS at 0 Gy, 70 Gy, and 3 months. CONCLUSION: The EAT-10 and pain reflected the FOIS score changes well, while two swallowing evaluations did not. To avoid aspiration, VF evaluation may not be necessary during CRT because of high correlations with pharyngeal residue on FEES.

    BACKGROUND: Adenoid cystic carcinoma is a rare malignant tumor arising from exocrine glands such as the major and minor salivary glands of the paranasal sinuses or the external auditory canal. Although multiple retrospective clinical studies of ACC have been reported to date, clinical questions, such as 1) long-term prognosis beyond 20 years, 2) usefulness and suitability for treatment of therapeutic interventions, 3) therapeutic goal to aim for, and 4) prognosis by recurrence sites, are still unclear. METHODS: To improve understanding and management of adenoid cystic carcinoma of the head and neck (ACC), a retrospective study with 58 new ACC cases between 1991 and 2016 was performed. The median observation period was 66.8 months (range 3-316 months). The overall clinical stages were as follows: I, 6.9%; II, 25.9%; III, 19.0%; and IV, 48.2%. Histology was cribriform/tubular type (C-T type) in 62.0% and solid type in 27.5%. The main treatment strategy was definitive surgery, which was performed in 75.2% of cases. RESULTS: Overall 10-year, 20-year, and 25-year survivals were 63.7, 27.3, and 20.0%, respectively. Similarly, disease-specific survival (DSSs) was 65.7, 51.2, and 38.4%, respectively, and disease-free survival was 25.2, 9.4, and 9.4%, respectively. Conducting surgery (HR: 0.19, 95% CI: 0.06-0.61, p = 0.005) and C-T type (HR: 0.32, 95% CI: 0.11-0.93, p = 0.036) were independent prognostic predictors of DSS. DSS was significantly prolonged after salvage surgery for both locoregional recurrence (p = 0.004) and lung metastatic recurrence (p = 0.012, vs best supportive care). CONCLUSIONS: In ACC cases, both initial surgical treatment and repetitive surgical resection of resectable recurrent lesions, including both locoregional and lung metastases, resulted in longer survival. The major goal of treatment for ACC may be long-term survival including cancer-bearing survival, resulting in either natural death or intercurrent-disease death, since judging cure of ACC is almost impossible. TRIAL REGISTRATION: Retrospectively registered.

    BACKGROUND: The latency of the swallowing reflex is an important factor causing dysphagia in head and neck cancer patients. Although there are many reports comparing voluntary swallowing function before and after treatment, few studies have focused on the latency of the swallowing reflex, which is a risk factor for pneumonia due to silent aspiration. The aim of this retrospective study was to clarify the changes in the latency of the swallowing reflex before and after treatment. METHODS: The latency of the swallowing reflex was quantified using the time from the injection of 1 ml of distilled water into the pharynx through a nasal catheter to the onset of swallowing. RESULTS: The latency time of the swallowing reflex was significantly decreased 3 months after treatment compared to before treatment. A significant reduction was also observed in patients with pharyngeal cancer who underwent chemoradiation therapy. CONCLUSIONS: This retrospective study showed that a delayed swallowing reflex improved with treatment in advanced head and neck cancer patients.

    OBJECTIVE: Surgery for locally advanced oral cancer often requires wide resections of multiple subsites of the oral cavity, including the oral tongue, floor of the mouth, and lower gingiva, and it causes chewing and swallowing disorders. The aim of this prospective, observational study was to determine which subsites have a greater impact on chewing and swallowing disorders after surgery. METHODS: A prospective, observational study was conducted involving 52 patients who underwent surgery for locally advanced oral cancer with free flap reconstruction. The patients' Functional Oral Intake Scale scores were measured before surgery and 1 and 3 months after surgery. Possible predictors of chewing and swallowing disorders were subjected to univariate analysis and multivariate logistic regression analysis. Age, sex, preoperative body mass index, clinical stage, extent of mandibular bone resection, floor of the mouth resection, total or subtotal glossectomy, laryngeal suspension, bilateral neck dissection, and postoperative radiation therapy were the variables evaluated. RESULTS: Multivariate logistic regression analysis showed that both anterior or extensive mandibular bone resection and postoperative radiation therapy were independently associated with poor oral intake after surgery. CONCLUSIONS: The identified predictors will be helpful for better management of patients identified as being at high risk of chewing and swallowing disorders.

    PURPOSE: To identify precipitating factors responsible for enteral nutrition (EN) dependency after concomitant chemoradiotherapy (CCRT) of head and neck cancers and to examine their statistical correlations. METHODS: Factors related to feeding condition, nutritional status, disease, and treatment of 26 oropharyngeal and hypopharyngeal cancer patients who received definitive CCRT were retrospectively investigated by examining their medical records. The days of no oral intake (NOI) during hospitalization and the months using enteral nutrition after CCRT were counted as representing the feeding condition, and the changes in body weight (BW) were examined as reflecting nutritional status. The factors related to EN dependency after CCRT were analyzed. RESULTS: Long duration of total NOI (≥ 30 days) and maximum NOI ≥ 14 days were significant predictors of EN dependency. Decreased BW (≥ 7.5 kg) was the next predictor identified, but it was not significant. Multivariate analysis showed that the total duration of NOI was more correlated with EN dependency than changes in BW. CONCLUSIONS: A long duration of NOI was more strongly related to EN dependency than nutritional factors.

    PURPOSE: To improve the diagnoses of the salivary gland tumors, a dynamic-enhanced MRI (dMRI) was investigated. METHODS: We conducted a retrospective chart review of 93 cases of salivary gland tumors. The histological diagnoses were obtained from all patients using a surgical specimen and/or an open biopsy specimen. The dMRI as well as fine-needle aspiration cytology (FNAC) and intraoperative frozen section (IFS) were analyzed. This study focused on the time-intensity curve (TIC) after injection, peak time (Tpeak), washout ratio (WR) as well as the gradient of enhancement and washout profile. RESULTS: The histological diagnoses included pleomorphic adenoma (PMA) in 53 cases, the Warthin tumors (WT) in 14 cases and malignant tumors (MT) in 26 cases. Incorrect diagnosis rate of FNAC and IFS were 5.2 and 8.3%, respectively. The TIC revealed differences among the three types of tumors. Tpeak as well as WR also revealed significant differences (p < 0.001). Tpeak were lower in order of WT, MT, PMA, respectively. WR of TICs at 30, 45 and 105 s after Tpeak were higher in order of WT, MT, PMA, respectively (p < 0.001). The gradient of increment and washout in the TIC curve was also an important parameter to distinguish the three types of tumors. In MT, the rapid enhancement pattern was found in high or intermediate histological grade tumors, whereas the slow enhancement pattern was exhibited in low grade tumors. CONCLUSIONS: Our findings indicate that using Tpeak and WR, it is possible to distinguish between WT, PMA and MT. Additionally, a rapid enhancement pattern may be a potential marker for these tumors.

    Here we present an extremely rare case of giant infantile hemangiopericytoma (HPC) of the tongue diagnosed prenatally by fetal ultrasonography and MR imaging. Due to airway stenosis, the patient was delivered by the ex utero intrapartum treatment (EXIT) procedure at 36 weeks of pregnancy. Initial diagnosis was infantile hemangioma based on physical examination, diagnostic imaging and the high incidence of hemangioma. The tumor was resistant to conservative treatments. Due to severe tumor hemorrhage, the nutrient vessel was embolized by endovascular treatment on the 73th day after birth. Two days after embolization, a hemiglossectomy was performed. Histological analysis after surgery diagnosed infantile HPC with microscopically positive stumps. After receiving adjuvant chemotherapy, the patient has had no recurrence after 53 months with normal speech and swallowing function resulting in normal growth. Our findings support that infantile HPC is one of the differential diagnosis of infantile hemangioma. The EXIT procedure could be effective for infants with upper respiratory stenosis by head and neck tumor diagnosed prenatally. Though complete resection is required for infantile HPC, our report suggests that a conservative surgical approach followed by adjuvant chemotherapy should be used for giant head and neck infantile HPC.
