RESUMO
BACKGROUND: Radiotherapy plus cetuximab (bioradiotherapy: BRT) is a standard option in the treatment of locally advanced squamous cell carcinoma of the head and neck (LA-SCCHN). Published data on its safety and efficacy in real-world settings is limited. Here, we conducted a prospective multi-institutional observational study to evaluate clinical outcomes of BRT in patients with LA-SCCHN. METHODS: We analyzed real-world data of all patients who underwent BRT from 2013 to 2016. The primary endpoint was 1-year progression-free survival (PFS). Secondary endpoints were 1-year locoregional PFS (LPFS), treatment completion rate (TCR), and adverse events (AEs). RESULTS: A total of 171 patients with a minimum 1-year follow-up were analyzed. Median age was 67 (36-85) years, and 37 patients (21.6%) were aged 75 years or older. 1-year PFS and LPFS were 51.5 and 56.1%, respectively. N stage (p = 0.049) was significantly associated with PFS. TCR was 77.2%. Cetuximab was definitively discontinued in 30 patients (17.5%), in 15 cases due to severe mucositis. N stage, T stage, and comorbidity were significantly associated with TCR. Major AEs of grade 3 or higher were pharyngeal mucositis (48.5%), radiation dermatitis (45.6%), and oral mucositis (40.4%). Pneumonitis was observed in 12 patients (7.0%); 6 cases (3.5%) were grades 3-4 and 2 (1.2%) were grade 5. CONCLUSION: As a result of the large number of elderly patients in clinical practice,ãtoxicity reduced TCR. BRT-induced pneumonitis, which is sometimes fatal, was found to be more frequent than with chemotherapy plus cetuximab.

BACKGROUND: We have previously reported the effectiveness and safety of nivolumab in patients with head and neck cancer (HNC) in real-world clinical practice in Japan. Here, we report long-term outcomes from this study in the overall population and subgroups stratified by subsequent chemotherapy. METHODS: In this multicenter, retrospective observational study, Japanese patients with recurrent or metastatic (R/M) HNC receiving nivolumab were followed up for 2 years. Effectiveness endpoints included overall survival (OS), OS rate, progression-free survival (PFS), and PFS rate. Safety endpoints included the incidence of immune-related adverse events (irAEs). RESULTS: Overall, 256 patients received a median of 6.0 doses (range: 1-52) of nivolumab over a median duration of 72.5 days (range: 1-736). Median OS was 9.5 months [95% confidence interval (CI) 8.2-12.0] and median PFS was 2.1 months (95% CI 1.8-2.7). A significant difference between 2-year survivors (n = 62) and non-2-year survivors was observed by median age (P = 0.0227) and ECOG PS (P = 0.0001). Of 95 patients who received subsequent chemotherapy, 54.7% received paclitaxel ± cetuximab. The median OS and PFS from the start of paclitaxel ± cetuximab were 6.9 months (95% CI 5.9-11.9) and 3.5 months (95% CI 2.3-5.5), respectively. IrAEs were reported in 17.2% of patients. Endocrine (7.0%) and lung (4.3%) disorders were the most common irAEs; kidney disorder (n = 1) was newly identified in this follow-up analysis. CONCLUSIONS: Results demonstrated the long-term effectiveness of nivolumab and potential effectiveness of subsequent chemotherapy in patients with R/M HNC in the real-world setting. Safety was consistent with that over the 1-year follow-up.

We report a case of mandibular osteosarcoma in a Japanese woman in her 70s who was p16-positive. Despite the rapid growth of the tumor, the patient responded well to chemotherapy and was then able to undergo surgery. Head and neck osteosarcoma (HNOS) is a very rare cancer, and although the importance of surgery has been pointed out, the effectiveness of chemotherapy is unclear. Resection margin negativity and response to chemotherapy have been reported as prognostic factors; another report assessed the effectiveness of the immunohistochemical expression of p16 protein as a predictor of response to chemotherapy.

BACKGROUND: It is well known that chemotherapy for adolescent and young adult (AYA) patients with cancer can reduce fertility regardless of the regimen. A decline in fertility greatly affects the quality of life of cancer survivors in the AYA age group; however, few patients are thought to be receiving fertility preservation measures. METHODS: A questionnaire survey was conducted to assess the current understanding and consideration of fertility among otorhinolaryngologists/head and neck surgeons who treat AYA patients with cancer, and to inform them of the guidelines for fertility preservation. A total of 275 otorhinolaryngologists/head and neck surgeons working at our hospital in Ehime, Japan, six neighboring universities, and their affiliated facilities were included in this study. The questionnaire was mailed and requested to be returned by fax. Twenty questions were asked about respondents' years of experience as physicians, specialties, experience in medical care and chemotherapy for AYA patients with cancer, and knowledge and experience in fertility reduction measures. RESULTS: Although 58.7% of the physicians were aware that cryopreservation of eggs and sperm prior to chemotherapy was recommended, only 7 out of 40 physicians (17.5%) had referred AYA patients with cancer to an appropriate medical facility (department) after obtaining informed consent for chemotherapy. CONCLUSIONS: Although fertility preservation has been discussed at professional conferences and seminars, consideration and actions in the field of otorhinolaryngology/head and neck surgery have not been sufficient. We hope that the results of this survey will help raise awareness of fertility preservation.

BACKGROUND: The aims of this study are to evaluate the efficacy and safety of first-line treatment with chemotherapy plus cetuximab in real-world patients with recurrent or metastatic squamous cell carcinoma of the head and neck (RM-SCCHN) and to identify prognostic factors for overall survival (OS). METHODS: This is a prospective observation study involving 20 oncology institutions in Japan. Patients with RM-SCCHN treated with a first-line therapy consisting of cetuximab plus any chemotherapy regimen between December 2013 and February 2017 were enrolled. The primary objective of the study was 1-year OS. Secondary objectives included response rate and adverse events. RESULTS: Of 120 patients recruited, 114 patients were analyzed. Median age was 64 years. Cetuximab in combination with platinum plus 5-FU (EXTREME regimen) was chosen in 86 patients (75.4%). The median OS was 12.4 months. A point estimate of the 1-year survival rate was 51.1%. Overall response rate was 26.3%. Grade 3 or worse adverse events included neutropenia (22.8%), hypokalemia (9.6%), acneiform rash (7.0%), pneumonitis (1.8%), and infusion-related reaction (0.9%). On multivariate analysis, regional lymph node metastasis, absence of intervention by dermatologists, lack of response to therapy, skin metastasis, and non-EXTREME regimen were identified as independent unfavorable prognostic factors for OS. CONCLUSION: The combination of cetuximab plus chemotherapy was tolerable and efficacious in patients with RM-SCCHN in a real-world setting. Clinical outcomes and prognostic factors extracted from this study provide a reference of the current clinical practice as well as for the future development of novel therapy in RM-SCCHN.

BACKGROUND: To examine the effect of prior use of cetuximab and neck dissection on the effectiveness of nivolumab, we conducted a large-scale subgroup analysis in Japanese patients with recurrent/metastatic head and neck cancer. METHODS: Data on the effectiveness of nivolumab were extracted from patient medical records. All patients were analyzed for effectiveness by prior cetuximab use. In the analyses for prior neck dissection, only patients with locally advanced disease were included. RESULTS: Of 256 patients analyzed, 155 had received prior cetuximab. Nineteen of 50 patients with local recurrence underwent neck dissection. The objective response rate was 14.7 vs 17.2% (p = 0.6116), median progression-free survival was 2.0 vs 3.1 months (p = 0.0261), and median overall survival was 8.4 vs 12 months (p = 0.0548) with vs without prior cetuximab use, respectively. The objective response rate was 23.1 vs 25.9% (p = 0.8455), median progression-free survival was 1.8 vs 3.0 months (p = 0.6650), and median overall survival was 9.1 vs 9.9 months (p = 0.5289) with vs without neck dissection, respectively. CONCLUSIONS: These findings support the use of nivolumab for patients with recurrent/metastatic head and neck cancer regardless of prior cetuximab use or neck dissection history. TRIAL REGISTRATION NUMBER: UMIN-CTR (UMIN000032600), Clinicaltrials.gov (NCT03569436).
RESUMO
BACKGROUND: To fill the data gap between clinical trials and real-world settings, this study assessed the overall effectiveness and safety of nivolumab in patients with head and neck cancer (HNC) during Japanese real-world clinical practice. METHODS: This was a multicenter, retrospective study in Japanese patients with recurrent or metastatic HNC who received nivolumab for the first time between July and December 2017. Data on the clinical use, effectiveness, and safety of nivolumab were extracted from patient medical records. RESULTS: Overall, 256 patients were enrolled in this study. The median duration of nivolumab treatment was 72.5 days, with patients receiving a median of 6.0 (range 1-27) doses. Median overall survival (OS) was 9.5 (95% confidence interval [CI] 8.2-12.0) months and the estimated 12-month OS rate was 43.2%. The objective response rate (ORR) was 15.7% overall and 21.1%, 7.1%, and 13.6% in patients with primary nasopharynx, maxillary sinus, and salivary gland tumors, respectively, who had been excluded from CheckMate 141. Grade ≥ 3 immune-related adverse events occurred in 5.9% of patients. No new safety signals were identified compared with adverse events noted in CheckMate 141. CONCLUSIONS: The effectiveness and safety of nivolumab in real-world clinical practice are consistent with data from the CheckMate 141 clinical trial. Therapeutic response was also observed in the groups of patients excluded from CheckMate 141. TRIAL REGISTRATION NUMBER: UMIN-CTR (UMIN000032600), Clinicaltrials.gov (NCT03569436).

BACKGROUND: Although the American Joint Committee on Cancer TNM classification has been amended to include human papillomavirus (HPV)-related oropharyngeal squamous cell carcinoma (OPSCC) as an independent entity, to the authors' knowledge the optimized de-escalating treatment modality has not been established to date. METHODS: The authors conducted a retrospective, nationwide, observational study in patients with HPV-related OPSCC who were treated from 2011 to 2014 in Japan to determine the best treatment modality. RESULTS: A total of 688 patients who were newly diagnosed with HPV-related OPSCC who were treated with curative intent at 35 institutions and had coherent clinical information and follow-up data available were included in the current study. In patients with T1-T2N0 disease (79 patients), both the 3-year recurrence-free survival and overall survival (OS) rates were 100% in the group treated with radiotherapy (RT) as well as the group receiving concurrent chemoradiotherapy (CCRT). The 3-year OS rates were 94.4% (for patients with T1N0 disease) and 92.9% (for patients with T2N0 disease) among the patients treated with upfront surgery. In patients with stage I to stage II HPV-related OPSCC, the 5-year recurrence-free survival and OS rates were 91.4% and 92%, respectively, in the patients treated with CCRT with relatively high-dose cisplatin (≥160 mg/m2 ; 114 patients) and 74.3% and 69.5%, respectively, in the patients treated with low-dose cisplatin (<160 mg/m2 ; 17 patients). CONCLUSIONS: Despite it being a retrospective observational trial with a lack of information regarding toxicity and morbidity, the results of the current study demonstrated that patients with T1-T2N0 HPV-related OPSCC could be treated with RT alone because of the equivalent outcomes of RT and CCRT, and patients with stage I to stage II HPV-related OPSCC other than those with T1-T2N0 disease could be treated with CCRT with cisplatin at a dose of ≥160 mg/m2 .

OBJECTIVES: To explore the risk factors of laryngo-esophageal dysfunction-free survival and nutritional support dependence over 12 months in patients with unresectable locally advanced head and neck carcinomas who received chemoradiotherapy in a phase II trial of JCOG0706 (UMIN000001272). METHODS: Forty-five patients received radiation therapy for a total of 70 Gy/35fr concurrently with S-1 and cisplatin. Risk factors of laryngo-esophageal dysfunction-free survival and nutritional support dependence over 12 months were analyzed using Cox regression models and logistic regression models, respectively, with consideration to patient laboratory data just before chemoradiotherapy. Radiation fields were reviewed to analyze the relationship between the extent of the irradiated field and functional outcome. RESULTS: With a median follow-up period of 3.5 years, 3-year laryngo-esophageal dysfunction-free survival was 48.9%. For laryngo-esophageal dysfunction-free survival, hazards ratio of 2.35 in patients with nutritional support at registration (vs. without nutritional support; 95% confidence interval 0.96-5.76). For nutritional support dependence over 12 months, odds ratio was 6.77 in patients with hemoglobin less than the median of 13.4 g/dl (vs. higher than or equal to the median; 95% confidence interval 1.24-36.85) and was 6.00 in patients with albumin less than the median of 3.9 g/dl (vs. higher than or equal to the median; 95% confidence interval 1.11-32.54). Primary sites in disease-free patients with nutritional support dependence over 12 months were the oropharynx (N = 2) or hypopharynx (N = 1), and all pharyngeal constrictor muscles were included in irradiated fields with a curative dose. CONCLUSIONS: This supplementary analysis showed that pretreatment severe dysphagia requiring nutritional support, anemia and hypoalbuminemia might have a negative prognostic impact on long-term functional outcomes after curative chemoradiotherapy in head and neck cancer.

OBJECTIVES: To evaluate the clinical impact of cachexia, defined by the combination of albumin and C-reactive protein levels, in patients with unresectable locally advanced head and neck squamous cell carcinomas who received chemoradiotherapy in a phase II trial of JCOG0706. METHODS: Forty-five patients received radiation for a total of 70 Gy/35fr concurrently with S-1 and cisplatin. The present analysis was conducted in 44 patients with available data. The association between treatment efficacy and cachexia was investigated. Pretreatment cachexia was defined as a serum albumin level of less than 3.5 mg/dl and C-reactive protein level of more than 0.5 mg/dl. RESULTS: Among the 44 patients, 5 patients had cachexia. On comparison with the cachexic and non-cachexic patients, the percentage of clinical complete remission (20% vs 72%), time to treatment failure at 3 years, (20% vs 53%) and proportion of treatment completion (20% vs 79%) were statistically worse in the cachexic patients, while overall survival, progression-free survival and local progression-free survival at 3 years tended to be worse in cachexic patients. CONCLUSIONS: This supplementary analysis from a prospective study suggests that a pretreatment status of cancer cachexia is a prognostic factor for treatment outcomes and compliance in patients with locally advanced head and neck squamous cell carcinomas treated with chemoradiotherapy, and a candidate stratification factor in future prospective trials in this population.

A number of major modifications were made to the classification of head and neck carcinomas in the eighth edition of the American Joint Committee on Cancer, Cancer Staging Manual and Union for International Cancer Control TNM classification of Malignant Tumors. These modifications were aimed at improving the prognosis prediction accuracy of the system. In this article, we review the new edition of the TNM classification system. Among the several changes in the new system, a separate algorithm for p16-positive oropharyngeal carcinoma was included, as were new chapters on 'Head and Neck Skin Carcinoma' and 'Unknown Primary Carcinoma-Cervical Nodes.' Changes to Tumor (T) classification were made by introducing the depth of invasion of oral carcinoma, whereas changes to Node (N) classification were made by adding extra-nodal extension. It is believed that these changes will help improve the accuracy of the system in the prediction of prognosis. However, it is necessary to verify their validity through further clinical research.

BACKGROUND: The aim of this study was to compare the therapeutic outcomes of total pharyngolaryngectomy with those of concomitant chemoradiotherapy in advanced hypopharyngeal cancer. METHODS: This is a retrospective multi-institutional study. The medical records of 979 patients with hypopharyngeal cancer, who were initially treated between 2006 and 2008, were reviewed. In this study, we matched a group of total pharyngolaryngectomy patients with a second group of chemoradiotherapy patients, according to age, gender, subsite, arytenoid fixation, cartilage invasion, and N classification, and analyzed overall survival, disease-specific survival, and locoregional control rates. RESULTS: The matched-pair analysis included 254 patients. The 5-year overall survival, disease-specific survival, and locoregional control rates were 58.5% and 53.5% (P = 0.30), 68.9% and 68.0% (P = 0.80), and 82.2% and 63.6% (P < 0.01), respectively, for patients in the total pharyngolaryngectomy and chemoradiotherapy groups. For T4a patients with cartilage invasion, the matched-pair analysis included 46 patients. The 5-year overall survival, disease-specific, and locoregional control rates were 56.5% and 26.0% (P = 0.092), 56.5% and 41.3% (P = 0.629), and 43.0% and 42.5% (P = 0.779), respectively, for patients in the total pharyngolaryngectomy and chemoradiotherapy groups. CONCLUSIONS: The data from this large-scale multi-institutional joint research program of hypopharyngeal cancer in Japan suggest that chemoradiotherapy may provide adequate survival benefit for hypopharyngeal cancer patients with the distinct advantage of larynx preservation. Our data also suggest that chemoradiotherapy is as beneficial as total pharyngolaryngectomy for the local control of locally advanced hypopharyngeal cancer.

We conducted a phase II study to evaluate the efficacy and safety of chemoradiotherapy concurrent with S-1 plus cisplatin in patients with unresectable locally advanced squamous cell carcinoma of the head and neck. Chemotherapy consisted of S-1 twice daily on days 1-14 at 60 mg/m(2) /day and cisplatin at 20 mg/m(2) /day on days 8-11, repeated twice at a 5-week interval. Single daily radiation of 70 Gy in 35 fractions was given concurrently starting on day 1. For patients achieving an objective response after chemoradiotherapy, two additional cycles of chemotherapy were administered. Of the 45 enrolled patients, the percentage of clinical complete remission, the primary endpoint, was 64.4% (8 complete response, 21 good partial response) on central review. After a median follow-up of 3.52 years, 3-year local progression-free survival was 62.2%, with 3-year progression-free survival of 60.0%, 3-year overall survival of 64.4%, and 3-year time to treatment failure of 48.9%. Grade 3 or 4 toxicity included pharyngeal mucositis (46.7%), oral mucositis (44.4%), dysphagia (46.7%), anorexia (42.2%), radiation dermatitis (26.7%), neutropenia (26.7%), and febrile neutropenia (4.4%). No treatment-related deaths were observed. This combination showed promising efficacy with acceptable toxicities.

BACKGROUND: The purpose of this study was to evaluate the incidence of lymph node metastasis among patients with T4 maxillary sinus squamous cell carcinoma (MS-SCC) as well as the delayed metastasis rate and the treatment outcome for untreated N0 neck in patients with T4 MS-SCC. METHODS: Consecutive series of all patients (n = 128) with previously untreated T4 maxillary sinus SCC between 2006 and 2007 were obtained from 28 institutions belonging to or cooperating in the Head and Neck Cancer Study Group of the Japan Clinical Oncology Group. RESULTS: Of the 128 patients, 28 (21.9 %) had lymph node metastasis, and six patients (4.7 %) had distant metastasis at diagnosis. Among the 111 patients who were treated with curative intent, 98 had clinically N0 neck disease and did not receive prophylactic neck irradiation. A total of 11 patients (11.2 %) subsequently developed evidence of lymph node metastasis, of whom eight were among the 83 patients with an N0 neck and had not received elective neck treatment. There were 15 patients who received an elective neck dissection as part of the initial treatment, of whom three had pathologically positive for lymph node metastases. Of 11 patients, six patients with nonlateral retropharyngeal lymph node metastasis without primary or distant disease were successfully salvaged. CONCLUSIONS: This study identified the incidence of lymph node metastasis among patients with T4 MS-SCC as well as the delayed metastasis rate and the treatment outcome for untreated N0 neck in patients with T4 MS-SCC. These results will be of assistance in selecting treatment strategy for T4 MS-SCC in the future.

OBJECTIVE: In Japan, cisplatin/5-fluorouracil 80/800 (cisplatin 80 mg/m2, 5-fluorouracil 800 mg/m2) is widely used to treat recurrent/metastatic squamous cell carcinoma of the head and neck, whereas cisplatin/5-fluorouracil 100/1000 (1000 mg/m2/24 h by continuous intravenous infusion on Days 1-4 plus cisplatin 100 mg/m2 on Day 1 in 3-week cycles) is the standard treatment in Europe and North America. METHODS: We prospectively evaluated the feasibility of cisplatin/5-fluorouracil 100/1000 in Japanese patients enrolled in the global Phase 3 study of panitumumab 9 mg/kg combined with cisplatin/5-fluorouracil 100/1000 (Arm 1) versus cisplatin/5-fluorouracil 100/1000 alone (Arm 2). RESULTS: Twenty Japanese patients were enrolled and received treatment (Arm 1, n=13; Arm 2, n=7). Grade 3/4 adverse events included neutropenia, hypomagnesemia, stomatitis, hyponatremia, paronychia, febrile neutropenia, decreased appetite and hypokalemia. There were no fatal adverse events. Median overall survival was not estimable in Arm 1 and 15.4 months in Arm 2. Median progression-free survival was 6.9 months in Arm 1 and 5.7 months in Arm 2. The median number of infusions (cycles) of cisplatin was 5 in Arm 1 and 4 in Arm 2; the median number of infusions (cycles) of 5-fluorouracil was 6 in both arms. The mean administered dose for cisplatin was 93.6 mg/m2 in Arm 1 and 97.2 mg/m2 in Arm 2, and 3732.6 and 3880 mg/m2 in Arm 1 and Arm 2, respectively, for 5-fluorouracil. CONCLUSIONS: These results suggested that cisplatin/5-fluorouracil 100/1000 was feasible for recurrent/metastatic squamous cell carcinoma of the head and neck in Japanese patients.

OBJECTIVES: Acute kidney injury (AKI) represents a major toxicity associated with cisplatin. We developed a risk prediction model for cisplatin-induced AKI in patients with postoperative high-risk head and neck cancer who received chemoradiotherapy during a randomized phase II/III trial, JCOG1008. MATERIALS AND METHODS: Two hundred and fifty-one patients received radiotherapy with weekly cisplatin at 40 mg/m2 (weekly arm) or 3-weekly cisplatin at 100 mg/m2 (3-weekly arm). AKI was defined using the AKI Network classification/staging system as increased serum creatinine of ≥0.3 mg/dL or a ≥1.5-fold increase from baseline 30 days after completing chemoradiotherapy. The Akaike information criterion was used to explore the optimal model by combining explanatory variables at registration. RESULTS: Among the 251 patients (210 men and 41 women (median age; 62 years)), 94 (37.5 %) developed cisplatin-induced AKI. The optimal cisplatin-induced AKI risk prediction model comprised four factors, including a primary site of hypopharynx/larynx (vs. oral cavity/oropharynx), 3-weekly arm (vs. weekly arm), serum albumin of ≤3.5 g/dL (vs. >3.5 g/dL) and creatinine clearance (CCr) of <90 mL/min (vs. ≥90 mL/min). The incidence of cisplatin-induced AKI rose with cumulative count of the four factors. When the cumulative count was ≥2, the positive predictive value for cisplatin-induced AKI was 50.3 %. CONCLUSIONS: We developed a risk prediction model for cisplatin-induced AKI in patients with head and neck cancer who received postoperative chemoradiotherapy using primary site, cisplatin administration method, serum albumin, and CCr. Patients with risk factors unrelated to the cisplatin administration method should adopt a weekly cisplatin regimen.

PURPOSE: To assess the efficacy and safety of apalutamide plus goserelin for androgen receptor (AR)-positive unresectable or recurrent/metastatic salivary gland carcinoma. PATIENTS AND METHODS: This trial was an open-label, single-arm, multicenter phase II study. Patients with histologically confirmed unresectable or recurrent/metastatic salivary gland carcinoma with AR expression were included. The primary endpoint was the overall response rate (ORR) according to RECIST v1.1 by an independent central radiology review in the first 24 response-evaluable (RE) patients who had been observed at least 24 weeks from study initiation (primary RE patients). The efficacy was to be declared when at least 8 of the 24 primary RE patients responded. RESULTS: A total of 31 patients were enrolled. In the first 24 primary RE patients with a median follow-up of 7.4 months, confirmed ORR by independent central radiology review was 25.0% [6/24 patients; 95% confidence interval, 9.8%-46.7%; P = 0.11 (one-sided)], which did not meet the predefined criteria of efficacy. Clinical benefit rate (ORR + rate of stable disease for at least 24 weeks) and median progression-free survival were 50.0% and 7.4 months, respectively. Both median duration of response and overall survival were not reached. Exploratory analyses showed a better ORR of 54.5% (6/11) in patients with AR positivity ≥70% and no history of prior systemic therapy. Grade 3 or higher treatment-emergent adverse events were reported in 35.5% (11/31), which included skin rash, anemia, leukopenia, and cancer pain. CONCLUSIONS: Although this study did not meet the predefined efficacy criteria, apalutamide plus goserelin showed clinically meaningful efficacy in a subset of patients with AR-positive salivary gland carcinoma and safety consistent with prior experience in prostate cancer.

BACKGROUND AND PURPOSE: Hypothyroidism is a recognized late adverse event following radiotherapy for head and neck cancer (HNC). In the JCOG1008 trial, we treated patients with high-risk HNC with postoperative chemoradiotherapy. We aimed to elucidate factors associated with hypothyroidism by analyzing the JCOG1008 data. MATERIALS AND METHODS: In 2012-2018, 261 patients from 28 institutions were enrolled in JCOG1008. Thyroid function tests were conducted to assess hypothyroidism, including free thyroxine (FT4) and thyroid-stimulating hormone assays. Hypothyroidism was defined as Grade 2 or higher in CTCAE v4.0. Various clinical and dosimetric parameters were analyzed. In radiotherapy, there were no dose constraints for the thyroid. Multivariable analysis was conducted on these variables to identify predictive factors for hypothyroidism. RESULTS: The analysis included 162 patients (57 with 3D-CRT and 105 with IMRT), with a median follow-up of 4.7 years (0.3-9.3 years). Among these, 27 (16.7 %) developed hypothyroidism within 2 years after radiotherapy. In a multivariable analysis, the weekly cisplatin [OR=7.700 (CI: 1.632-36.343, p = 0.010)] and baseline FT4 [OR=0.009 (CI: <0.001-0.313, p = 0.010)] were significantly associated with hypothyroidism in the IMRT group. Regarding dosimetric characteristics, V60Gy [OR=1.069 (CI: 0.999-1.143, p = 0.054)] was potentially associated with the development of hypothyroidism. CONCLUSION: The study revealed that the incidence of hypothyroidism within 2 years after postoperative chemoradiotherapy for high-risk HNC was 16.7 % based on analytical results from prospective clinical trials.

OBJECTIVE: The current study aimed to compare the therapeutic outcomes of surgery with those of chemoradiation for patients with advanced oropharyngeal cancer (OPC). METHODS: The data for 523 patients with previously untreated OPC were obtained from 12 institutions belonging to the Head and Neck Cancer Study Group in the Japan Clinical Oncology Group from April 2005 to March 2007. In this study, we matched a group of patients who underwent surgery with a second group treated with chemoradiation according to age, gender, subsite, and T and N classification, and analyzed the overall survival, progression-free survival, local control and swallowing function. RESULTS: The final matched-pair analysis included 186 patients. The 5-year overall survival, progression-free survival and local control rates were 69.8 and 71.4% (p = 0.762), 51.0 and 54.4% (p = 0.531), and 75.2 and 80.3% (p = 0.399), respectively, in patients treated with surgery and those treated with chemoradiation. Swallowing function in patients treated with chemoradiation was significantly better than that in patients treated with surgery (p = 0.015). CONCLUSION: Although this study was not randomized, this matched-pair analysis of patients treated with surgery or chemoradiation showed that chemoradiation is as effective as surgery in the treatment of OPC.
