First-Line Immunochemotherapy Versus Palliative Chemotherapy Plus Definitive Radiation Therapy for de novo Metastatic Nasopharyngeal Carcinoma: A Matched Cohort Study.

ABSTRACT:

Background

The combined use of immune checkpoint inhibitors (ICIs) with palliative chemotherapy (PCT) is a promising first-line treatment for de novo metastatic nasopharyngeal carcinoma (mNPC). However, the efficacy of ICIs with PCT vs PCT with definitive radiation therapy (DRT) remain unclear.

Methods

Patients with mNPC who received first-line immunochemotherapy (ICI + PCT) or PCT + DRT were included. Propensity score matching (PSM) was applied to balance potential confounders between patients who did and did not undergo DRT (at a ratio of 1:1). Progression free survival (PFS) and overall survival (OS) were compared between the 2 groups using a log-rank test and Cox proportional hazard model.

Results

Among all participants, 149 received ICI + PCT. After PSM, 149 pati
