57 citations
,
January 1986 in “The Prostate” This article discusses the role of dihydrotestosterone in human prostatic adenocarcinoma growth and suggests that 6-methyleneprogesterone could be used to inhibit DHT for treating hormone-responsive prostate cancer, without new clinical findings.
9 citations
,
March 1991 in “Endocrinology” This study in rats suggests that combining the 5 alpha-reductase inhibitor 4-MA with the antiandrogen Flutamide may enhance prostate cancer therapy by additively inhibiting prostatic growth and mRNA levels of androgen-sensitive prostatic binding proteins.
