Background: Alveolar ridge (AR) squamous cell carcinoma (SCC) is poorly represented on prospective clinical trials. Adjuvant management is extrapolated from more common head and neck SCC, including those with a stronger influence from the human papillomavirus. The objective of this analysis is to determine the association between adjuvant radiotherapy (RT) and overall survival (OS) for resected ARSCC based on adverse pathologic features. Methods: Adult subjects in the National Cancer Database diagnosed with invasive nonmetastatic ARSCC between 2010–2014 were identified. Exclusion criteria included prior malignancy, no/unknown surgery, unknown receipt of RT, RT dose <50 Gy or >80 Gy, RT fractions >68, T1–2N0 disease without identifiable NCCN-defined risk factors (positive margin, lymphovascular invasion, pT3–4, N2–3, extranodal extension, or level IV/V nodal metastasis), and unknown/missing NCCN risk factor data. Log-rank test stratified by RT and Cox regression analyses with respect to OS were performed. Results: 1,450 subjects met inclusion criteria, of which 825 (57%) received RT. Median follow-up was 27 months. Adjuvant RT was associated with improved OS (72% vs 65% at 2 years, log-rank P=.004). Stratified by number of NCCN-defined risk factors, adjuvant RT was associated with improved OS for subjects with 2 (74% vs 58% at 2 years, log-rank P<.001) and ≥3 (54% vs 29% at 2 years, log-rank P<.001) risk factors. Adjuvant RT was significantly associated with improved OS on univariate (HR, 0.80; 95% CI, 0.68–0.94; P=.008) and multivariate (HR, 0.72; 95% CI, 0.60–0.87; P=.001) analyses, the latter adjusted for age, comorbidity score, and adverse pathologic features. Each NCCN-defined risk factor, high tumor grade, primary tumor ≥3 cm, and ≥5% nodal positivity (number of pathologic nodes positive among nodes resected) were significantly associated with worse OS on univariate and multivariate analyses. Conclusions: Adjuvant RT for resected ARSCC with adverse pathologic features is associated with significantly improved OS. Subjects with a primary tumor ≥3 cm, high tumor grade, and ≥5% nodal positivity in addition to the NCCN-defined risk factors should be considered for adjuvant RT.

National Analysis

Objective The objective of this study was to analyze national trends in human papillomavirus (HPV) testing for patients diagnosed with sinonasal squamous cell carcinoma (SNSCC). Study Design Retrospective database study. Setting National Cancer Database (2010-2016). Methods Cases from 2010 to 2016 with a primary SNSCC diagnosis and known HPV testing status were extracted from the National Cancer Database. Univariate and multivariate analyses were then performed to assess differences in socioeconomic, hospital, and tumor characteristics between tested and nontested patients. Results A total of 2308 SNSCC cases were collected, with 1210 (52.4%) HPV tested and 1098 (47.6%) not tested. On univariate analyses, patient age, insurance, income quartile, population density, treatment facility location, and tumor grade were significantly associated with HPV testing status. After multivariate logistic regression modeling, living in a suburban area had lower odds of HPV testing as compared with living in urban areas (odds ratio, 0.74 [95% CI, 0.55-0.99]; P = .041), while tumor grade III/IV had higher odds than grade I (odds ratio, 1.73 [95% CI, 1.29-2.33]; P < .001). HPV-tested patients had a similar 5-year overall survival to nontested patients (48.3% vs 45.3%, log-rank P = .405). A sharp increase in HPV testing rates was observed after 2010 ( P < .001). Conclusion Among patients with SNSCC, those with high-grade tumors were more likely to be tested for HPV, while patients with a suburban area of residence were less likely. Additionally, there was no significant survival benefit to HPV testing, with tested and nontested groups having similar overall survival. Level of evidence 4.

(1) Oesophageal squamous cell carcinoma is common in Africa and has a male preponderance. The gender-based differences in clinical presentation and risk factor exposure are poorly studied in the African context. Our aim was to compare males and females with this disease. We analyzed the differences in clinical features and risk factor exposure between males and females with oesophageal cancer. (2) Data from patients presenting to a tertiary hospital in South Africa with oesophageal squamous cell carcinoma were analyzed. Data collected included patient demographics, clinical presentation, pathology and risk factor exposure. (3) Three hundred and sixty three patients were included in the study. The male to female ratio was 1.4:1. The mean age was 66 years for females and 61 years for males (p < 0.0001). A significantly larger percentage of males were underweight compared to females (60% vs. 32%, p < 0.001). There were no differences between the genders with regards to performance status, dysphagia grade and duration and tumor length, location and degree of differentiation. There were significant differences between risk factor exposure between the two genders. Smoking and alcohol consumption was an association in more than 70% of males but in less than 10% of females There was no difference survival. (4) Female patients with oesophageal squamous cell carcinoma (OSCC) are older and have a higher body mass index (BMI) than their male counterparts. Traditionally purported risk factors of smoking and alcohol consumption are infrequent associations with OSCC in female patients and other environmental risk factors may be more relevant in this gender.

e18551 Background: Treatment for locally advanced head and neck squamous cell carcinoma (HNSCC) involves a combination of surgery, chemotherapy, and radiotherapy (RT). RT for HNSCC is a known risk factor for the development of hypothyroidism. Recently, anti-PD1 therapies have been approved for recurrent and metastatic HNSCC and are moving to the forefront of HNSCC care. Similarly, thyroid dysfunction is a common immune-related adverse event following anti-PD1 therapy. Whether the addition of anti-PD1 to RT increases the likelihood of developing hypothyroidism remains unknown. Methods: The rate of hypothyroidism in HNSCC patients receiving RT (+/- chemotherapy and surgery) was compared to HNSCC patients receiving RT + anti-PD1 therapy either concurrently or after RT. Exclusion criteria were preexisting thyroid dysfunction, RT dose < 45 Gy and patients with incomplete treatment records. We defined clinical hypothyroidism as an elevation of TSH with low T3, T4 or elevation of TSH with symptoms requiring levothyroxine initiation. Hypothyroidism incidence was compared using Fisher’s exact test. Results: 153 patients were evaluated. In the RT group (N = 103), patients received RT +/- surgery or chemotherapy. 82/103 (80%) were male, median age was 57 and primary tumor groups included oropharynx 62/103 (60%), larynx 29/103 (28%), oral cavity 9/103 (9%) and other 3/103 (3%). In the RT + anti-PD1 group (N = 50), 36/50 (72%) were males, median age was 57 and primary tumor groups included oral cavity 19/50 (38%), oropharynx 17/50 (34%), larynx 8/50 (16%), and other 6/50 (12%). In the RT group, median follow up after RT was 801 days. In the RT+ anti-PD1 group, median follow up was 595 days from RT and 388 days from anti-PD1. The rate of hypothyroidism was significantly higher in the RT group 22.3% (23/103) versus 6% (3/50)after anti-PD1 therapy (p = 0.011). Multinomial logistical regression found no significant difference in hypothyroidism based on age, sex, or BMI. Larynx as primary tumor location was an independent risk factor for development of hypothyroidism (OR 4.74, p = 0.002). Conclusions: The addition of anti-PD1 therapy to standard HNSCC treatments does not significantly increase the risk of developing hypothyroidism. In fact, this study finds a lower incidence of hypothyroidism in HNSCC patient receiving RT + PD1 therapy which may be due to shorter duration of follow up and lower proportion of laryngeal cancer patients who are at relatively higher risk for surgical hypothyroidism.

Abstract Background:Radiotherapy and chemoradiation are well-established therapies for patients with squamous cell carcinoma of the head and neck (SCCHN). In aging societies, also the incidence of SCCHN in elderly patients is rising. Because of the underrepresentation of elderly patients in scientific trials, we evaluated the feasibility of adjuvant radiotherapy and chemoradiation in patients with SCCHN aged >70 years. Methods:All patients had been >70 years at the time of diagnosis and received adjuvant radiotherapy or, if feasible, chemoradiation at the University Medical Centre Regensburg between 2004 and 2018.71 patients -most with SCCHN UICC stage IVa- with a median age of 75 years were included; 9 patients received concomitant chemoradiation. Median follow-up was 27 months (IQR 18 – 62 months).Results:Radiotherapy and chemoradiation was well tolerated. 62 patients (87.3%) underwent treatment without interruption, and 65 patients (91.5%) completed radiotherapy with 95% of the initially prescribed dose. Median dose for all patients was 64 Gy (IQR: 60 – 66 Gy). 6/9 patients received at least 75 % of the planned chemotherapy dose. 37 patients (52.1%) developed acute toxicity CTC grade III or IV.Overall survival was 87 % after 12 months, 67 % after 24 months and 41 % after 60 months. Median overall survival was 51 months (IQR: 19 - 99 months). Local tumour control was 99 % after 12 months, 88 % after 24 months and 76 % after 5 years.Conclusion:Feasibility of adjuvant radiotherapy and chemoradiation in our collective of elderly patients with SCCHN was good. Particularly local tumour control was satisfactory. Overall survival does not seem to differ between elderly and younger patients or patients unselected for age. De-intensification of treatment because of age does not seem justified.
