Association Between Head and Neck Squamous Cell Carcinoma Survival, Smoking at Diagnosis, and Marital Status.

ABSTRACT: Importance:While the adverse association between smoking and head and neck squamous cell carcinoma (HNSCC) survival has been well described, there are also inconclusive studies and those that report no significant changes in HNSCC survival and overall mortality due to smoking. There is also a lack of studies investigating the association of marital status on smoking status at diagnosis for patients with HNSCC. Objective:To examine the association between patient smoking status at HNSCC diagnosis and survival and the association between marital status and smoking in these patients. Design, Setting, and Participants:This retrospective cohort study was conducted by querying the Saint Louis University Hospital Tumor Registry for adults with a diagnosis of HNSCC and treated at the university academic medical center between 1997 and 2012; 463 confirmed cases were analyzed. Main Outcomes and Measures:Cox proportional hazards regression analysis was used to evaluate association of survival with smoking status at diagnosis and covariates. A multivariate logistic regression model was used to assess whether marital status was associated with smoking at diagnosis adjusting for covariates. Results:Of the 463 total patients (338 men, 125 women), 92 (19.9%) were aged 18 to 49 years; 233 (50.3%) were aged 50 to 65 years; and 138 (29.8%) were older than 65 years. Overall, 56.2% of patients were smokers at diagnosis (n?=?260); 49.6% were married (n?=?228); and the mortality rate was 54.9% (254 died). A majority of patients were white (81.0%; n?=?375). Smokers at diagnosis were more likely to be younger (ie, <65 years), unmarried, and to drink alcohol. We found a statistically significant difference in median survival time between smokers (89 months; 95% CI, 65-123 months) and nonsmokers at diagnosis (208 months; 95% CI, 129-235 months). In the adjusted Cox proportional hazards model, patients who were smokers at diagnosis were almost twice as likely to die during the study period as nonsmokers (hazard ratio, 1.98; 95% CI, 1.42-2.77). In the multivariate logistic regression analysis, unmarried patients were 76% more likely to use tobacco than married patients (adjusted odds ratio, 1.76; 95% CI, 1.08-2.84). Conclusions and Relevance:Smokers were almost twice as likely as nonsmokers to die during the study period. We also found that those who were married were less likely to be smokers at diagnosis. Our study suggests that individualized cancer care should incorporate social support and management of cancer risk behaviors.

Project description:ImportanceData are limited on the prognostic value of human papillomavirus (HPV) status for head and neck carcinoma subsites.ObjectiveTo determine whether HPV positivity at each head and neck subsite is associated with improved overall survival.Design, setting, and participantsThis retrospective population-based cohort study used the National Cancer Database to identify patients diagnosed with head and neck squamous cell carcinomas from January 1, 2010, to December 31, 2014. Patients were classified according to the location of their primary malignancy into 1 of the 6 main subsites of the upper aerodigestive tract: oral cavity, oropharynx, nasopharynx, hypopharynx, larynx, and sinonasal tract. Patients were also classified by their HPV status. Data collection for this study took place from January 1, 2010, to December 31, 2014. Data analysis was conducted from August 1, 2017, to September 30, 2017.Main outcomes and measuresThe difference in 5-year overall survival between patients with HPV-positive status and those with HPV-negative status in various head and neck carcinoma subsites; the role of HPV status in an unadjusted Cox multivariate regression model.ResultsOf the 175 223 total number of patients identified (129 634 [74.0%] male; 45 589 [26.0%] female; mean [SD] age, 63.1 [11.9] years), 133 273 (76.1%) were ineligible and 41 950 (23.9%) were included in the sample. This sample included 16 644 patients (39.7%) with HPV-positive tumors and 25 306 (60.3%) with HPV-negative tumors. Patients with an HPV-positive status were more likely to be younger, be white, be male, present with local T category tumors, and have poor differentiation on histologic examination. HPV-positive status was associated with survival at 4 tumor subsites: oral cavity (hazard ratio [HR], 0.76; 95% CI, 0.66-0.87), oropharynx (HR, 0.44; 95% CI, 0.41-0.47), hypopharynx (HR, 0.59; 95% CI, 0.45-0.77), and larynx (HR, 0.71; 95% CI, 0.59-0.85). The HPV status was the greatest factor in survival outcome between the HPV-positive and -negative cohorts at the oropharynx subsite (77.6% vs 50.7%; survival difference, 26.9%; 95% CI, 25.6%-28.2%) and hypopharynx subsites (52.2% vs 28.8%; survival difference, 23.4%; 95% CI, 17.5%-29.3%). For the nasopharynx (HR, 1.03; 95% CI, 0.75-1.42) and sinonasal tract (HR, 0.63; 95% CI, 0.39-1.01) subsites, HPV-positive status was not an independent prognostic factor.Conclusions and relevanceHuman papillomavirus positivity was associated with improved survival in 4 subsites (oropharynx, hypopharynx, oral cavity, and larynx), and the largest survival difference was noted in the oropharynx and hypopharynx subsites. In the nasopharynx and sinonasal tract subsites, HPV positivity had no association with overall survival. Given these results, routine testing for HPV at the oropharynx, hypopharynx, oral cavity, and larynx subsites may be warranted.

Project description:For TP53-mutated head and neck squamous cell carcinomas (HNSCCs), the codon and specific amino acid sequence change resulting from a patient's mutation can be prognostic. Thus, developing a framework to predict patient survival for specific mutations in TP53 would be valuable. There are many bioinformatics and functional methods for predicting the phenotypic impact of genetic variation, but their overall clinical value remains unclear. Here, we assess the ability of 15 different methods to predict HNSCC patient survival from TP53 mutation, using TP53 mutation and clinical data from patients enrolled in E4393 by the Eastern Cooperative Oncology Group (ECOG), which investigated whether TP53 mutations in surgical margins were predictive of disease recurrence. These methods include: server-based computational tools SIFT, PolyPhen-2, and Align-GVGD; our in-house POSE and VEST algorithms; the rules devised in Poeta et al. with and without considerations for splice-site mutations; location of mutation in the DNA-bound TP53 protein structure; and a functional assay measuring WAF1 transactivation in TP53-mutated yeast. We assessed method performance using overall survival (OS) and progression-free survival (PFS) from 420 HNSCC patients, of whom 224 had TP53 mutations. Each mutation was categorized as "disruptive" or "non-disruptive". For each method, we compared the outcome between the disruptive group vs. the non-disruptive group. The rules devised by Poeta et al. with or without our splice-site modification were observed to be superior to others. While the differences in OS (disruptive vs. non-disruptive) appear to be marginally significant (Poeta rules + splice rules, P = 0.089; Poeta rules, P = 0.053), both algorithms identified the disruptive group as having significantly worse PFS outcome (Poeta rules + splice rules, P = 0.011; Poeta rules, P = 0.027). In general, prognostic performance was low among assessed methods. Further studies are required to develop and validate methods that can predict functional and clinical significance of TP53 mutations in HNSCC patients.
