Associations between Human Papillomavirus Status, Weight Change, and Survival of Oropharyngeal Cancer Patients.

This study examined associations between HPV status and weight change in oropharyngeal cancer (OPC). OPC patients receiving concurrent chemoradiotherapy in Toronto, Canada were included. Relationships were assessed between HPV status and weight loss grade (WLG, combining weight loss and current body mass index); weight change during treatment; and HPV status and WLG/weight change on overall (OS) and cancer-specific (CSS) survival.

Cigarette smoking cessation, duration of smoking abstinence, and head and neck squamous cell carcinoma prognosis.

Background: Tobacco use is a major risk factor for developing head and neck squamous cell carcinoma (HNSCC). However, the prognostic associations with smoking cessation are limited. The authors assessed whether smoking cessation and increased duration of abstinence were associated with improved overall (OS) and HNSCC-specific survival.
