[Androgen-independent prostate cancer with bone metastasis successfully treated by intravenous administration of zoledronic acid and diethylstilbestrol diphosphate].
A 67-year-old man was diagnosed as having prostate cancer with bone metastasis by his personal physician in 2002. He received androgen deprivation therapy, and then prostate specific antigen (PSA) declined to an undetectable level over the short term. In 2004, PSA gradually became elevated despite androgen deprivation therapy. Although secondary hormonal therapy was started, PSA continued to increase. With the complaint of back pain, he consulted our clinic. On initial examination at our clinic, PSA was 390.3 ng/ml and alkaline phosphatase (ALP) was 2,338 IU/L. He was administered diethylstilbestrol diphosphate (DES-DP) and zoledronic acid intravenously and then PSA declined to an undetectable value again. In the course of the administration, liver enzymes were elevated and DES-DP administration was discontinued. However, with continued administration of zoledronic acid, PSA remained undetectable despite a 5-month interruption of DES-DP treatment. Thereafter, back pain completely disappeared.
