[Radiation therapy of carcinoma of the vulva].

Thirty-three patients suffering from squamous cell carcinoma of the vulva were treated with radiation therapy alone between 1961 and 1980 at the NIRS. The five-year survival rate and local control rate in each stage were 91% and 36% in T2 and 71% and 64% in T3, respectively. These results indicated that the early detection of recurrent tumor by close follow-up and an adequate retreatment procedure is very important for prolonging survival. Late recurrence, more than five years after treatment, appeared in 30% of the patients and this may be one of the special figures of postirradiated vulval carcinoma. The primary site was irradiated with external electron beams or radium needles, and better results were obtained with the later. Irradiation to the lymph node area in the pelvic cavity was necessary in patients with a more advanced stage of disease than T2.
