title: Para-aortic lymph node irradiation in carcinoma of the cervix after exploratory laparotomy and biopsy-proven positive aortic nodes.
abstract: From July 1970 to January 1977, 23 patients with previously untreated cancer of the cervix (CA CX), mostly Stage IIIB, were included in this study. The para-aortic lymph nodes (PALN) were histologically documented to have metastatic disease in all 23 patients. External radiation treatment (RT) was delivered using a Cobalt--60 machine to a spade-shaped field to treat the pelvic cavity and para-aortic area. The majority of the patients received 4000-6000 rad to the pelvic cavity and from 5000-5500 rad to the PALN's by external RT. In addition, intracavitary radium was used in 21 patients. Five patients are alive and free of disease at 115, 110, 90, 73 and 45 months after completion of RT. One survivor had clinical Stage IB, one had Stage IIB, and three had Stage IIIB cervical carcinoma. Two of 15 patients with clinically enlarged and suspicious para-aortic nodes are alive, while 3 of 8 patients with clinically normal appearing nodes survived. Three (60%) of the survivors developed late bowel radiation damage. Eighteen patients died--10 during the first year, 3 during the second year, 2 during the third year, 1 during the fourth year and 2 during the eighth year of the follow-up. Five (27.8%) of the patients who died had developed late bowel radiation damage. Fifteen of the 18 died with disease at an average of 21 months. Three patients died of intercurrent disease. Their average survival was 40 months, double that of patients dying of disease. This report suggests that in cancer of the cervix, radiation therapy can control some PALN metastatic disease, but the risk of complications is rather high. In the absence of better methods of management, this risk of complications is justifiable because the alternative is to leave known disease untreated.
