fosfestrol and Fatty-Liver

The parenchymal damage of the liver after estrogen therapy for prostatic cancer, mainly treated with diethylstilbestrol diphosphate (DES-DP), was studied in the six autopsied cases, herein. The parenchymal disorder of the liver was "nonalcoholic steatohepatitis", reported by Ludwig et al., and its degree of disorder was dependent upon the administered dose of estrogen. The acceptable total dose of DES-DP was supposed to be about 150 g at maximum, according to the various degrees of damage examined histopathologically in the six cases who were administered at total doses of DES-DP from 12.6 g to 619 g. Comparison of the histopathologic damage to the liver function tests performed within 10 days before death revealed that only the serum levels of cholinesterase (ChE) were abnormally decreased, suggesting its importance to predict the degree of "nonalcoholic steatohepatitis" by monitoring of ChE.

We have examined the value of cholinesterase (ChE) that indicates the preservation ability of liver function, to assess the liver disorder owing to diethylstilbestrol diphosphate (DES-DP) administration in 25 prostatic cancer patients without castration. The correlation between ChE and the other factors such as age, total dose of DES-DP, duration of administration or ratio (total dose/duration), were studied by means of multiple regression analysis (MRA). In sixteen patients treated for less than 6 months, ChE was correlated with all factors by MRA with the coefficient of 0.645, and the coefficients of simple correlation between ChE and total dose and between ChE and administered duration, were -0.521 (p less than 0.05) and -0.596 (p less than 0.05), respectively. In nine patients treated for more than 6 months, ChE was correlated with all factors by MRA with the coefficient of 0.803, and the coefficient of simple correlation between ChE and ratio was -0.707 (p less than 0.05). According to these results and the permissible range of ChE, the total dose of administration for less than 6 months was estimated to be under 50 gram and its duration was within 100 days. The ratio in patients administered for more than 6 months was under 300 mg/day. Therefore, as far as the long-term hormonal treatment for prostatic cancer and preservation of liver function, we concluded that total dose of DES-DP should be less than 50 gram in less than 100 days for induction therapy and the daily dose of DES-DP should be less than 300 mg/day for maintenance therapy.
