[Standardization for postoperative irradiation of cervical uterine cancer]

Three hundred and ten patients with carcinoma of the uterine cervix received postoperative radiation therapy and the relationship between the extent of lymph node metastases and the prognosis was analysed. Patients with lymph node metastases showed a markedly lower five-year survival rate (42.1%) than those without such metastases (91.9%). The prognosis for patients with lymph node metastases was inversely correlated to the number of nodes involved. Bilateral lymph node involvement or para-aortic node metastases gave a much poorer prognosis than unilateral involvement. From these data, standardization for postoperative irradiation of cervical uterine cancer were discussed and summarized.
