Comments on “Radiotherapy alone versus concurrent chemoradiotherapy in patients with stage II and T3N0 nasopharyngeal carcinoma with adverse features: A propensity score-matched cohort study”

We read the article entitled "Radiotherapy alone versus concurrent chemoradiotherapy in patients with stage II and T3N0 nasopharyngeal carcinoma with adverse features: A propensity score-matched cohort study" by Zhang et al [1] with great interest. The findings of the study indicated that adding concurrent chemotherapy to radiotherapy did not contribute to improved survival rates in patients with stage II and T3N0 nasopharyngeal carcinoma (NPC) with adverse factors. This is a substantial study as it comprehensively evaluates this controversial issue with a large number of patients and propensity score-matching analysis.
