Serum concentrations of testosterone, oestrogens, luteinizing hormone and follicle-stimulating hormone in male and female rats during the critical period of neural sexual differentiation.

Untreated male and female rat pups were killed 1--5 days post partum and the serum concentrations of testosterone, oestrogens, LH and FSH were determined by radioimmunoassay. At all five sampling times, the serum concentrations of testosterone in male rats were about three times higher than those in female rats, but serum levels of oestrogens did not differ between the sexes. Serum concentrations of LH and FSH were lower in male than in female pups. In another study, rats were decapitated 1--10 days after birth and serum concentrations of testosterone were determined with a different radioimmunoassay. Again, at all four sampling times, the concentration of testosterone was significantly higher in the male than in the female pups.

Combined irradiation and surgery in the treatment of stage II carcinoma of the endometrium.

Between January 1969, and August 1975, 40 patients with pathologic Stage II carcinoma of the endometrium were treated at the Joint Center for Radiation Therapy. The treatment policy included external and intracavitary irradiation combined with surgery. The majority of patients received 4000 mg/hours of radium exposure using a Fletcher-Suit applicator and 4000 rad whole pelvis external irradiation, followed by hysterectomy and bilateral salpingooophorectomy. Median age of the patients was 61 years (39--88) and the median follow-up of the patients still alive was 69 months (29--102). Relapse-free 5-year survival corrected for intercurrent disease was 83% and uncorrected, 78%. Overall survival was 80%. Five patients had relapsing disease, three patients failed at distant sites only, one patient died of treatment related complications, and two failed locally and distantly. There were no failures in the pelvis alone. Although the relationshop between histologic grade and failure is not statistically significant, there were four failures among the 12 Grade III patients compared to two failures in 27 with Grades I and II. Similarly, 4 of 12 patients with gross cervical involvement developed relapsing disease, but only 2 of 28 failed with microscopic cervical involvement. This treatment policy yields excellent survival and continues to be our treatment recommendation.

Can pelvic irradiation be omitted in patients with pathologic stages IA and IIA Hodgkin's disease?

From April 1969 to December 1973, 81 unselected laparotomy-staged IA and IIA patients with supradiaphragmatic Hodgkin's disease were treated at the Joint Center for Radiation Therapy. Mantle and para-aortic fields alone were treated to 3600-4000 rads. Median follow-up was 31 months. There were six relapses including three true recurrences, two extensions, and one extra-nodal dissemination. Relapses were not related to histologic type. There were no pelvic or inguinal extensions. Disease-free survival was 95% in stage IA patients and 86% in stage IIA patients. Only one patient died of disease, with an overall survival of 96%. These results indicate that mantle and para-aortic irradiation is sufficient treatment for pathologic stage I and IIA supradiaphragmatic Hodgkin's disease. Such treatment obviates the need for pelvic irradiation or combination chemotherapy without compromising the success of treatment.
