Dramatic Decline of PSA and Symptom Improvement after Estramustine Withdrawal in a Hormone-refractory Prostate Cancer Patient / 대한비뇨기과학회지

ABSTRACT

In some patients with prostate cancer and who manifest disease progression during maximal androgen blockade(MAB) therapy, discontinuation of antiandrogen treatment might result in a significant fall in the level of serum prostate-specific antigen(PSA), and this is often correlated with clinical improvement(antiandrogen withdrawal syndrome). However, a decline in the PSA level after the withdrawal of estramustine phosphate is extremely rare. We report here on a case of dramatic decline in the PSA level after withdrawal of estramustine phosphate in a patient with hormone refractory prostate cancer.
