My dad (76; lives abroad) was diagnosed with prostate cancer in January this year by exam. Urologist felt a lump. Two out of six biopsies were positive for prostae cancer, Gleason 7 (3,4). His PSA was 0.8 and repeated 1.2. He had US of abdomen but no other workup. Prostate size is 26.3 cm3 and size of the tumor 1.62 x 0.47 x 1.4 cm. He is otherwise in reasonable shape, still works several hours a day and has stable angina (not an issue for few years), history of TIA in 2005 and hypertension.
His urologist started him on Androcur (cyproteronum) and Zoladex.
Reading about it, the hormonal therapy is used in the US only for metastatic cancer, which my dad does not have.
What would be the recommended treatement (radiation, brachytherapy, surgery)?
Is hormonal treatment sufficient? How will they know if the cancer progresses (his PSA is low)?
Can hormonal therapy reduces the size of cancer? Do you get resistent to it?
What are the chances (%) of this stage of cancer to metastasize and shorten my dad's survival?
Would you recommend bone scan or CT?
Thanks you
