Elective upper-neck versus whole-neck irradiation of the uninvolved neck in patients with nasopharyngeal carcinoma reply

We thank Yu-Ming Wang and colleagues for their comments on our Article. 1 Tang LL Huang CL Zhang N et al. Elective upper-neck versus whole-neck irradiation of the uninvolved neck in patients with nasopharyngeal carcinoma: an open-label, non-inferiority, multicentre, randomised phase 3 trial.

Elective upper-neck versus whole-neck irradiation of the uninvolved neck in patients with nasopharyngeal carcinomaWe would like to congratulate Ling-Long Tang and colleagues1 for their recently published trial on de-escalation strategies to decrease radiation volume in patients with early-stage nasopharyngeal cancer. In the Results section of their Article, omission of part of the neck in the radiotherapy field did not increase the risk of neck nodal relapse and resulted in fewer toxic effects than whole-neck irradiation. However, from a radiobiological standpoint, we would like to highlight concerns about the prescription of elective irradiation.
