Competing mortality in oropharyngeal carcinoma according to human papillomavirus status

Background The objective of the present study is to assess differences in the competing causes of death in patients with oropharyngeal carcinoma (OPC) as a function of the human papillomavirus (HPV) status. Methods We studied retrospectively 423 patients with OPC with known HPV status. Among the patients included in the study, 53 (12.5%) were HPV‐positive. We analyzed overall survival and competing causes of mortality according to the HPV status of the patients. Results Patients with HPV‐negative tumors had lower OPC cancer‐specific survival ( P  = .0001), second primary neoplasm survival ( P  = .0001), and noncancer‐related causes survival ( P  = .13) than patients with HPV‐positive tumors. This resulted in significant differences in overall survival depending on HPV status ( P  = .0001).Conclusion Conclusion: HPV‐positive OPC has a better overall survival than HPV‐negative OPC. Patients with HPV‐positive tumors presented a significant lower OPC cancer‐specific and second primary neoplasm mortality and a marginally nonsignificant lower noncancer mortality as compared to HPV‐negative tumors.
