Treatment outcome of oropharyngeal squamous cell carcinoma through propensity score analysis
Brazilian journal of otorhinolaryngology(2023)
摘要
According to an extensive database, the Objective is to compare surgical versus nonsurgical treatment through Propensity Score (PS) for patients with Oropharyngeal Squamous Cell Carcinoma (OPSCC).Methods: We retrospectively evaluated epidemiological data from 8075 patients with OPSCC diagnosed between 2004 and 2014 and used PS matching to analyze possible prognostic factors for its outcomes with regression analyses.Results: Cox multiple regression analysis to study survival after PS matching shows that type of treatment was associated with death with a hazard ratio of 1.753 (p < 0.05) of non-surgical treatment. However, it was not associated with recurrence (p > 0.05). In the surgical treatment group, overall survival was 79.9% at one year, 36.4% at five years, and 20.5% at ten years. Disease-free survival was 90.1%, 64.8%, and 56.0% at 1, 5, and 10-years, respectively. In the non-surgical treatment group, overall survival was 60.6% at one year, 21.8% at five years, and 12.7% at ten years. Disease-free survival was 90.8%, 67.2%, and 57.8% at 1, 5, and 10-years, respectively.Conclusion: Patients in the surgical treatment group had better outcomes related to survival. Recurrence is associated with the survival of OPSCC cancer. Recurrence-free survival is similar to both treatments.Level of evidence: 2C.(c) 2023 Associac,ao Brasileira de Otorrinolaringologia e Cirurgia C ' ervico-Facial. Published by Elsevier Espana, S.L.U.
