Historical Cohort

Objectives To describe patterns of primary surgical treatments in patients with T4b oral cavity squamous cell carcinoma (OCSCC). Study Design Historical cohort study. Setting National Cancer Database. Methods Review of the National Cancer Database between 2004 and 2017 for all T4b OCSCCs. Only patients with curative treatment methods were included in the survival analysis. Surgical and nonsurgical outcomes were compared by multivariable and propensity score matching analysis. Results A total of 1515 cases of T4b OCSCC were identified. A minority of patients (n = 363, 24.0%) underwent curative treatment; among these, 206 (56.7%) underwent primary surgery. Median length of follow-up was 24 months. The 90-day mortality of patients who underwent surgical treatment was 1.0%. The 2-year survival was higher for patients who underwent surgery + chemoradiotherapy (CRT) as compared with CRT (64.6% vs 45.2%, P < .001). On multivariable analysis, surgery + CRT was associated with longer survival. In a propensity score–matched cohort of 312 patients, 2-year survival remained higher in the surgical group versus the nonsurgical group (59.4% vs 45.5%, P = .02). Among patients who underwent surgery + CRT, there was no difference in 2-year survival between clinical T4a and T4b (59% vs 64.6%, P = .20). Conclusions A minority of patients with T4b OCSCC undergo treatments with curative intent. A subset of patients underwent primary surgical treatment, which was associated with longer survival. The T4b classification might entail a heterogenous group, and further studies in revision of this classification might be justified.

Objective Assess the testing rates and prognostic significance of human papilloma virus (HPV) status in hypopharynx malignancies. Study Design Historical cohort study. Setting National Cancer Database. Methods Review of the National Cancer Database was conducted between 2010 and 2017 for squamous cell carcinomas (SCCs) of the hypopharynx. We investigated how often the tumors were tested for HPV and whether it was associated with survival outcomes. Results A total of 13,269 patients with hypopharynx malignancies were identified. Most cases were not tested for HPV status (n = 8702, 65.6%). Of those tested, 872 (19.1%) were positive for HPV and 3695 (80.9%) were negative. The proportion of nonoropharyngeal SCCs tested for HPV increased nearly every year during the study, with roughly one-third of cases (31.9%) being tested in 2017. In the facilities classified as high-testing centers of nonoropharyngeal SCCs of the head and neck, 18.7% of hypopharyngeal tumors were HPV positive. HPV-negative status was associated with worse survival on multivariable analysis. In propensity score–matched analysis controlling for all factors significant in multivariable regression, 2-year survival remained higher in the HPV-positive cohort (77.7% vs 63.1%, P < .001). Conclusions HPV-positive tumors constitute a sizable minority of hypopharynx tumors and are associated with improved survival. Expansion of HPV testing to hypopharynx malignancies may be warranted.

Objective To analyze the patterns of care and survival of cutaneous angiosarcomas of the head and neck. Study Design Retrospective cohort study. Setting National Cancer Database. Methods The National Cancer Database was queried to select patients with cutaneous angiosarcoma of the head and neck between 2004 and 2015. For survival analysis, patients were included only if they received definitive treatment and complete data. Prognostic factors were analyzed by univariate and multivariable Cox regression. Results We identified 693 patients diagnosed with head and neck angiosarcomas during the study period. The majority were male (n = 489, 70.6%) and elderly (median, 77 years). A total of 421 patients (60.8%) met the criteria for survival analyses. These patients were treated with surgery and radiation (n = 178, 42.3%), surgery alone (n = 138, 32.8%), triple-modality therapy (n = 48, 11.4%), surgery and chemotherapy (n = 29, 6.9%), and chemoradiation (n = 28, 6.7%). With a median follow-up of 29 months, the 3-year survival was 50.1%. Patients undergoing surgery had better median survival than those who did not (38.1 vs 21.0 months, P = .04). Age, comorbidity, tumor size, and surgical margins were significant factors in univariate analyses. On multivariable analysis, age ≥75 years (hazard ratio, 2.65; 95% CI, 1.80-3.88; P < .001) and positive margins (hazard ratio, 1.91; 95% CI, 1.44-2.51; P < .001) predicted worse overall survival. Conclusion Angiosarcoma of head and neck is a rare malignancy that affects the elderly. Surgical treatment with negative margins is associated with improved survival. Even with curative-intent multimodality treatment, the survival of patients aged ≥75 years is limited.

635 Background: Optimal timing for surgical treatment of localized renal cell carcinoma (RCC) remains undefined. We sought to determine the survival impact of time to definitive surgical treatment for Stage 1 RCC and elucidate factors associated with a delay in surgical care utilizing the National Cancer Database (NCDB). Methods: The NCDB was queried for Stage 1 RCC cases (cT1N0M0) from 2004-2013 treated with partial or radical nephrectomy. Quartiles were formed from the range of time to surgery of the entire cohort in days: early defined as the first two quartiles and delayed as the fourth. Descriptive analyses were conducted between early and delayed groups. Overall survival (OS) between early and delayed groups was calculated with Kaplan-Meier analysis. Multivariable analysis was performed to determine factors associated with delay in surgical care. Results: 38,859 patients were analyzed. Median time to treatment was 40 days (IQR 22-68). Early (≤40 days, n = 23,712) and delayed ( > 68 days, n = 15,147) groups had a median follow-up of 44.8 and 41 months, respectively (p < 0.001). Delayed surgery was more frequent with African-Americans (14.8% vs. 9.1%, p < 0.001), patients with government or no insurance (53.7% vs. 45.1%, p < 0.001), males (60.7% vs. 58.3%, p = 0.001), and Charlson Comorbidity Index (CCI) ≥2 (9.7% vs. 6.7%, p < 0.001). Kaplan-Meier analysis demonstrated survival benefit to the earlier treatment group, with 5 year OS of 85.5% and 80.9% (p < 0.001; Figure). On multivariable analysis, increasing age (OR = 1.001, p = 0.015), African-American race (OR = 1.5, p < 0.001), increasing distance from treatment center (OR = 1.005, p = 0.001), residence in areas with low high school graduation rates (OR = 1.42, p < 0.001), residence in an area of > 1 million population (OR = 1.6, p < 0.001), and CCI ≥2 (OR = 1.4, p < 0.001) were independently associated with increasing time to surgery. Conclusions: Surgery of T1 RCC carried out beyond 9 weeks after diagnosis is associated with reduced overall survival compared to patients treated within 6 weeks. Time to definitive surgical treatment should be a quality of care metric, with special attention given to populations most at risk for delays in care.

Purpose: Although clinicians encounter patients aged ≥70 years with locally advanced oral cavity squamous cell carcinoma (LA-OCSCC), no evidence is available to facilitate decision making regarding treatment for this elderly population. Methods: We selected elderly (≥70 years) patients from the Taiwan Cancer Registry database who had received a diagnosis of LA-OCSCC. Propensity score matching was performed. Cox proportional hazards model curves were used to analyze all-cause mortality in patients in different age groups receiving different treatments. Results: The matching process yielded a final cohort of 976 patients in concurrent chemoradiotherapy (CCRT), non-treatment, radiotherapy (RT) alone, and surgery cohorts who were eligible for further analysis. After stratified analysis, the adjusted hazard ratios (aHRs) (95% confidence intervals [CIs]) derived for surgery, RT alone, and non-treatment compared with CCRT were 0.66 (0.52 to 0.83), 1.02 (0.81 to 1.28), and 1.52 (1.21 to 1.91), respectively, in patients aged 70 to 80 years. In the oldest patients (aged >80 years), multivariate analysis indicated that the results of surgery or RT alone were nonsignificant compared with those of CCRT. The aHR (95% CI) derived for the highest mortality was 1.81 (1.11 to 2.40) for non-treatment compared with CCRT. Conclusions: Surgery for elderly patients with LA-OCSCC is associated with a significant survival benefit, but the association is nonsignificant in the oldest elderly patients. No survival differences were observed between RT alone and CCRT in these elderly patients. Non-treatment should not be an option for these patients.
