Histopathological findings after preoperative chemo-radiotherapy in oral and oropharyngeal carcinoma. A study of 28 resected specimens.
Serial sections of whole surgical specimens from 28 patients with locally advanced oral carcinoma were examined to assess the histopathological effects of a preoperative intravenous (i.v.) chemotherapy and radiotherapy protocol. In 15 cases (54%), no residual neoplastic tissue was found: in 9, the tumour area showed a dense hyalinised connective tissue, whereas in the other 6 cases foci of keratotic material were surrounded by a foreign body-type reaction. In 13 patients (46%), residual neoplastic tissue was observed: small fields of tumour were present in 6 cases, whereas tumour was widely persistent in 7. Lymph node metastases were observed in 9 cases (32%), with extracapsular spreading in 6 (21%). In 93% of cases, pathological staging on the specimen was more favourable than the clinical preoperative staging. 23 patients (82%) are alive without evidence of disease 30-55 months after surgery; 10 (43%) did not show any residual neoplastic tissue in the specimen; 10 patients (43%) showed persistence of tumour, but in 5 (21%) only small fields of tumour were observed. 4 patients (14%) died due to their tumour. The pathological data show that this protocol is successful in the treatment of advanced oral carcinoma; furthermore, they provide reliable information about the response to therapy and the subsequent course of the disease.
