title: [Liver disorder owing to estrogen therapy in prostatic cancer. The correlation between serum level of cholinesterase and dose of diethylstilbestrol diphosphate].
abstract: 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.
