Weight Change Trajectory in Patients With Locally Advanced Nasopharyngeal Carcinoma During the Peri–Radiation Therapy Period

According to the International Agency for Research on Cancer, about 129,000 new cases of nasopharyngeal carcinoma (NPC) were diagnosed in 2018 (Bray et al., 2018; Tang, Chen, et al., 2016). Unlike other head and neck cancers, NPC is highly sensitive to radiation therapy; because of the distinct anatomical location for NPC, radiation therapy is the mainstay treatment modality (Chen et al., 2019; Chow, 2020; Chua et al., 2019; Colevas et al., 2018; He, Wu, et al., 2017; Sun et al., 2020).
