Abstract
We report treatment of intermediate risk prostate cancer in a patient with a brief period of androgen deprivation secondary to a pituitary adenoma. This was a patient with intermediate risk prostate cancer diagnosed in the setting of an elevated prostate-specific antigen (PSA). The patient subsequently demonstrated a decline in PSA along with symptoms of hypogonadism and visual disturbance, and was consequently found to have a pituitary tumour. Trans-sphenoidal resection of the sellar mass was performed with normalisation of hormone profiles. The patient subsequently completed a course of radiation therapy for prostate cancer with PSA nadir to undetectable levels without evidence of biochemical recurrence at 7 months follow-up.
