[Clinical evaluation of chemohormonal therapy as an initial treatment for stage D2 prostatic cancer--effect of UFT administration combined with hormonal therapy].

We evaluated the usefulness of hormonal therapy combined with UFT as initial treatment in comparison with hormonal therapy alone in 92 patients with Stage D2 prostatic cancer treated at the Department of Urology, Dokkyo University School of Medicine between 1974 and 1993. Twenty-six of these patients were treated with diethylstilbestrol diphosphate (DESP) and castration (hormonal therapy alone group), and 23 patients were treated with UFT, DESP and castration (UFT combined therapy group). The 5-year survival rates calculated with Kaplan-Meier's method in the hormonal therapy alone group and the UFT combined therapy group were 34.6 % and 38.3%, respectively. However, the 3-year survival rates of pathologically poorly differentiated adenocarcinoma in these groups were 30.0% and 50.0%, respectively. Based on these results, it was suggested that UFT administration combined with hormonal therapy is useful for pathologically poorly differentiated adenocarcinoma in Stage D2 prostatic cancer.
