Complete response to the combination therapy with androgen blockade and somatostatin analogue in a patient with advanced prostate cancer: magnetic resonance imaging with 1H-spectroscopy

Abstract

A 74-yr-old man with prostatic adenocarcinoma underwent magnetic resonance 1H-spectroscopic imaging (1H-MRSI) of the prostate. Based on the results, he was treated with combination therapy using complete androgen blockade (leuprorelin acetate 3.75 mg every 4 wk plus bicalutamide 50 mg daily) and a somatostatin analogue (lanreotide acetate 60 mg every 4 wk). Serum prostate-specific antigen and chromogranin A levels steadily decreased over a 12-mo follow-up period, at which time the patient is alive without disease progression and with a complete objective and symptomatic response.
