Abstract
Data from 119 patients with nasopharyngeal carcinoma who were under 30 years of age were retrospectively analyzed by the investigators of the Childrens Cancer Study Group. The overall five‐year survival and relapse‐free survival rates from diagnosis were 51 and 36%, respectively. When the tumor was confined to the nasopharynx (T1 + T2, 41 patients), the five‐year survival was 75%. No significant correlation was found between survival or local recurrence and the radiation dose to the primary site. The five‐year survival from relapse was 37% for 21 reirradiated patients with local and/or regional relapse compared with 11% for 45 patients with other forms of relapse. It is concluded that the optimal radiation dose for tumor eradication in young patients is not known.
