Tang L-L, Huang C-L, Lin S-J, et al. Primary target volume delineation for radiotherapy in nasopharyngeal carcinoma: CSTRO, CACA, CSCO, HNCIG, ESTRO, and ASTRO guidelines and contouring atlas. Lancet Oncol 2025; 26: e477–87—In this Policy Review, the first sentence of Recommendation 3.3 should have read, “Posteriorly delineate the anterior third of the clivus (the cortex) if uninvolved (usually for T1 and T2 disease) and include the whole clivus (inferior, posterior column, up to the posterior clinoid process) for any clival involvement (usually for T3 and T4 disease).” This correction has been made to the online version as of Dec 22, 2025.
