[Effective hormone therapy of prostatic cancer with lung metastasis: 2 cases]

Many prostatic cancer patients have local symptoms such as dysuria and hematuria, but relatively few are seen with lung metastasis. This time we experienced 2 cases of prostatic cancer with a lung metastasis focus as the first symptom. Administration of diethylstilbestrol 500 mg/day for 20 days produced marked effects; reduction or disappearance of the lung metastasis focus, noticeable reduction of prostatic tumor and the improvement of their total condition. The literature is also reviewed.
