Amlodipine on blood vessels of prostate

June 6, 2009

Question:

Can Amlodipin cause increased capillary pressure in Prostate and thereby increase its volume so as to increase bladder neck obstruction?

Answer:

I can find no medical references indicating that amlodipine can cause any change in prostate volume. Amlodipine was actually studied alone and in combination with another drug to treat symptoms associated with an enlarged prostate. The study did not show any benefit from amlodipine use alone on prostate-related symptoms, though.

MRI: Effective Tool For Determining Pathologic Stage Of Prostate Cancer

April 25, 2009

In patients with prostate cancer undergoing prostatectomy, MR imaging plays an important role in determining if the cancer is restricted to the prostate gland or if it has spread beyond the capsule, according to a study performed at the University of California, Los Angeles, Los Angeles, CA.

The study included a review of 119 patients who were referred for prostate MRI prior to prostatectomy. “Results showed that MRI correctly identified 87/92 (95%) of patients with T2 and 6/8 (75%) of patients with T3 disease (T2 means the disease is organ confined and T3 means the disease has locally spread beyond the prostate),” said Timothy McClure, MD, lead author of the study. Steven Raman, MD, worked with Dr. McClure on this study.

PROVENGE Significantly Prolongs Survival In Men With Advanced Prostate Cancer In Pivotal Phase 3 IMPACT Study

April 20, 2009

Mary Crowley Cancer Research Centers in Dallas, Texas announced that the pivotal Phase 3 IMPACT study of PROVENGE(R) (sipuleucel-T) in men with advanced prostate cancer met its primary endpoint of improving overall survival compared to a placebo control. The magnitude of the survival difference observed in the intent to treat population resulted in the study successfully achieving the pre-specified level of statistical significance defined by the study’s design. The safety profile of PROVENGE appeared to be consistent with prior trials. Mary Crowley is the local researcher in this trial.

Study Looks At Association Between Sexual Orientation, Race/Ethnicity And Prostate, Colon Cancer Screening Rates

January 16, 2009

“Sexual Orientation and Testing for Prostate and Colorectal Cancers Among Men in California,” Medical Care: The study, led by Kevin Heslin, an assistant professor at the Charles Drew University of Medicine and Science, examines prostate and colorectal cancer screening rates based on sexual orientation and race and ethnicity. Researchers analyzed data on 19,410 men who participated in a statewide health survey (Heslin et al., Medical Care, December 2008). Researchers looked at the use of prostate-specific antigen testing among gay/bisexual and heterosexual men and found no significant differences. However, the percentage of black gay/bisexual men who had undergone the test was 15% to 28% lower than gay/bisexual whites and 12% to 14% lower than heterosexual black men. The finding is significant because black men are more likely to be diagnosed with prostate cancer than any other racial or ethnic group (University of California-Los Angeles Center for Health Policy Researchnewsletter, December 2008). The study suggests that further research be conducted to examine racial and ethnic differences in cancer testing (Medical Care, December 2008).

Diffusion And Perfusion MR Imaging Of The Prostate

January 12, 2009

UroToday.com – The current gold standard for diagnosis of prostate cancer is the Transrectal Ultrasound (TRUS) guided prostate biopsy, initiated by elevated PSA-levels or a Digital Rectal Examination (DRE) suspicious for prostate cancer. However TRUS and TRUS-guided biopsies are known to have high false-negative rates, up to 30% with random sextant biopsies 1, 2. In the PSA era probably more low-volume prostate cancers are detected, leading to higher false-negative rates with random TRUS-guided biopsies, even when schemes with increasing numbers of random biopsy cores are used.

Additional Positive Findings For APOPTONE (HE3235) In Preclinical Models Of Castration-Resistant Prostate Cancer

January 6, 2009

Hollis-Eden Pharmaceuticals, Inc. (NASDAQ:HEPH) today presented new findings that suggest APOPTONE™ (HE3235) is inhibiting in preclinical models of castration-resistant prostate cancer, the ability of tumors to synthesize the hormones necessary for their survival, as well as significantly down regulating the androgen receptor. Recent reports from the scientific literature indicate that androgen receptor signaling is active in all stages of prostate cancer, including late stage castration-resistant prostate cancer, and that castration-resistant prostate cancer may be driven by the intratumoral production of androgens. The Company’s new findings were reported this week at the 13th International Congress on Hormonal Steroids and Hormones & Cancer being held in Quebec City, Canada, September 27th – 30th. Dr. Richard Trauger, Director of Infectious Disease and Cancer at Hollis-Eden Pharmaceuticals, presented the data, from work performed by Dr. Eva Corey, Research Associate Professor, Department of Urology, at the University of Washington.
