Does first-line tislelizumab plus chemotherapy improve long-term outcomes compared with placebo plus chemotherapy in participants with recurrent or metastatic nasopharyngeal cancer?In this randomized clinical trial including 263 participants, tislelizumab plus chemotherapy demonstrated sustained progression-free survival benefit (median, 9.6 months vs 7.4 months) and clinically meaningful overall survival improvement (median, 45.3 months vs 31.8 months) compared with placebo plus chemotherapy after 3 years of follow-up, which is consistent with the interim analysis.These findings support tislelizumab plus chemotherapy as a first-line treatment for recurrent or metastatic nasopharyngeal cancer, with the potential to provide sustained, long-term survival benefit.
