A randomized trial of progestogens in the primary treatment of endometrial carcinoma.

A randomized trial was arranged in Yorkshire to assess whether progestogens would improve survival as part of the primary treatment of endometrial carcinoma, in conjunction with surgery and radiotherapy. A total of 429 patients was randomized on diagnosis to the progestogen or control group and treated locally according to an agreed protocol. All the patients are now more than 1 year after operation and over half are more than 5 years after operation. The projected overall 5-year survival rate is 76% but contrary to expectation there is no statistically significant difference in survival between the patients treated with progestogens and the control group even after statistical adjustment for known prognostic factors.

Comparative effect of pethidine, trichloroethylene, and Entonox on fetal and neonatal acid-base and PO2.

The second stage of labour is associated with relative fetal hypoxia and progressive metabolic acidosis. Maternal analgesia can increase the danger, especially for the high-risk fetus.In 152 patients the effect on the fetus of pethidine alone, pethidine + trichloroethylene, or pethidine + Entonox was assessed by fetal scalp blood sampling. Fetal pH, Pco(2), and Po(2) were measured and base excess was calculated. Capillary samples were also taken 45 to 60 minutes after birth in 88 of the babies to estimate the rate of neonatal recovery.Entonox proved safer than trichloroethylene, and babies treated with it maintained their Po(2) before birth, had better Apgar scores at birth, and one hour later were significantly less acidotic and much better oxygenated.
