Combined androgen blockade therapy can convert RT-PCR detection of prostate-specific antigen (PSA) and prostate-specific membrane antigen (PSMA) transcripts from positive to negative in the peripheral blood of patients with clinically localized prostate cancer and increase biochemical failure-free survival after curative therapy.

Background: The clinical relevance of positive molecular staging as defined by reverse transcriptase-polymerase chain reaction (RT-PCR) detections of both prostate-specific antigen (PSA) and prostate-specific membrane antigen (PSMA) transcripts in the peripheral blood (PB) of patients with prostate cancer is still debatable.

Methods: We analyzed the biochemical failure-free survival (bFFS) of prostate cancer patients with positive molecular staging who underwent immediate curative therapy (Group I, n=39) compared to prostate cancer patients who did convert their positive molecular staging by the administration of combined androgen blockade (CAB) for 12 months prior to curative treatment (Group II, n=15).

Results: The median bFFS for Group I was 9 months (95% CI 5-13 months) and was significantly lower compared to Group II (>36 months, p<0.

New strategies for the treatment of hormone-independent prostate cancer.

Prostate cancer is the most frequently diagnosed cancer and the second leading cause of death in men in the United States. Androgen ablation therapy is useful and results in stabilization or regression of the disease in approximately 80% of patients, but it invariably fails to prevent progressive disease. Prostate cancer that progresses in the presence of androgen blockade is defined as hormone-refractory prostate cancer (HRPC).

Randomized controlled clinical trial of a combination of somatostatin analog and dexamethasone plus zoledronate vs. zoledronate in patients with androgen ablation-refractory prostate cancer.

Background: As previously shown, the combination of standard androgen ablation therapy with somatostatin analog and dexamethasone in metastatic androgen ablation-refractory (stage D3) prostate cancer (PrCa) patients has a favorable profile of side-effects, durable objective antitumor activity (up to 60% partial response rate) and palliative effects. Bisphosphonates interfere with bone remodeling at the sites of PrCa bone metastases and have been postulated to have indirect and/or direct anti-PrCa activity.

Materials And Methods: A randomized controlled clinical trial was conducted to compare a combination of somatostatin analog (octreotide 20 mg i.

Serum testosterone: A potentially adjunct screening test for the assessment of the risk of prostate cancer among men with modestly elevated PSA values (> or =3.0 and <10.0 ng/ml).

Whether serum testosterone (T) can become an adjunct test able to validate the PSA-weighted risk of prostate cancer (PR.CA) in the "grey" diagnostic area (PSA =3.0 to <10.
