Abstract

A prospective analysis of 69 patients who had been treated for nasopharyngeal carcinoma (NPC) by external radiotherapy was carried out. Biopsies from the posterior nasopharynx were performed and analyzed by in situ hybridization using an antisense Epstein-Barr Early RNA (EBER) radio-labelled riboprobe. None of the patients had evidence of disease in the nasopharynx. One patient was found to have nasopharyngeal carcinoma detected only by in situ hybridization. In the subsequent 18-month follow-up of these clinically- and biopsynegative patients, only one patient developed relapse in the nasopharynx. In situ hybridization is a valuable tool for the detection of NPC and should be routinely available in histopathology laboratories where NPC is regularly diagnosed.
