In vitro engineering of a bone metastases model allows for study of the effects of antiandrogen therapies in advanced prostate cancer | Science Advances

In vitro engineering of a bone metastases model allows for study of the effects of antiandrogen therapies in advanced prostate cancer | Science Advances Abstract While androgen-targeted therapies are routinely used in advanced prostate cancer (PCa), their effect is poorly understood in treating bone metastatic lesions and ultimately results in the development of metastatic castrate resistant prostate cancer (mCRPC). Here, we used an all-human microtissue-engineered model of mineralized metastatic tissue combining human osteoprogenitor cells, 3D printing and prostate cancer cells, to assess the effects of the antiandrogens, bicalutamide, and enzalutamide in this microenvironment. We demonstrate that cancer/bone stroma interactions and antiandrogens drive cancer progression in a mineralized microenvironment. Probing the bone microenvironment with enzalutamide led to stronger cancer cell adaptive responses and osteomimicry than bicalutamide. Enzalutamide presented with better

Black Men Less Likely to Get Best Prostate Cancer Treatments

Black Men Less Likely to Get Best Prostate Cancer Treatments webmd.com Black Men Less Likely to Get Best Prostate Cancer Treatments 3-4 minutes By Robert Preidt HealthDay Reporter TUESDAY, June 29, 2021 (HealthDay News) -- Black American military veterans with aggressive prostate cancer who would benefit from surgery or radiation are less likely to get those treatments than men of other races, despite equal access to health care, a new study finds. "Despite great strides in prostate cancer care over the past few decades, racial disparities in care persist, and there remains a lot to be done to better understand why this is happening and what we can do to finally close the gap," said senior investigator Dr. Danil Makarov, a urologic surgeon at NYU Langone's Perlmutter Cancer Center, in New York City. For the study, the researchers analyzed the medical records of more than 3

Bipolar Androgen Therapy Effective in Metastatic Castration-Resistant Prostate Cancer — Cancer ABCs

Bipolar Androgen Therapy Effective in Metastatic Castration-Resistant Prostate Cancer — Cancer ABCs cancerabcs.org Bipolar Androgen Therapy Effective in Metastatic Castration-Resistant Prostate Cancer — Cancer ABCs 3-4 minutes Hormone Therapy (ADT) is the standard of care for prostate cancer. ADT is practiced by either halting the production of androgens or blocking them from interacting with the hormone receptor, so the cancer cells cannot utilize the androgens.   This method of ADT usually results in the development of resistance where the therapy stops working and the cancer continues to progress.    There has been discussion and some recent evaluation of an alternative type of

Metformin Added to Hormone Therapy (ADT) Has Positive Effects on Prostate Cancer — Cancer ABCs

Metformin Added to Hormone Therapy (ADT) Has Positive Effects on Prostate Cancer — Cancer ABCs In some of our earlier posts, I have suggested that there is evidence that adding an older and inexpensive drug, Metformin, can provide some anticancer effects for men with prostate cancer.   Metformin is an old standby drug commonly used to treat diabetes by controlling glucose blood levels. A recent randomized controlled trial has confirmed that it also has a significant positive effect on men with prostate cancer. The study showed when Metformin is added to the standard of care hormone therapy (ADT) in men with locally advanced and metastatic hormone-sensitive prostate cancer (HSPC or prostate cancer that is still responsive to the ADT) that castrate-resistant prostate cancer-free survival (CRPC-FS) was significantly improved from 20 months to 29 months. The study also indicated that men with locally advanced and low volume of disease derived the most benefit from Metformin. In a

Lutetium-177–PSMA-617 for Metastatic Castration-Resistant Prostate Cancer | NEJM

Lutetium-177–PSMA-617 for Metastatic Castration-Resistant Prostate Cancer | NEJM Abstract Background Metastatic castration-resistant prostate cancer remains fatal despite recent advances. Prostate-specific membrane antigen (PSMA) is highly expressed in metastatic castration-resistant prostate cancer. Lutetium-177 ( 177 Lu)–PSMA-617 is a radioligand therapy that delivers beta-particle radiation to PSMA-expressing cells and the surrounding microenvironment. Methods We conducted an international, open-label, phase 3 trial evaluating 177 Lu-PSMA-617 in patients who had metastatic castration-resistant prostate cancer previously treated with at least one androgen-receptor–pathway inhibitor and one or two taxane regimens and who had PSMA-positive gallium-68 ( 68 Ga)–labeled PSMA-11 positron-emission tomographic–computed tomographic scans. Patients were randomly assigned in a 2:1 ratio to receive either 177 Lu-PSMA-617 (7.4 GBq every 6 weeks for four to six cycles) plus protocol-

Prostate Cancer Drug Improves COVID-19 Survival in Trial

Prostate Cancer Drug Improves COVID-19 Survival in Trial medscape.com Prostate Cancer Drug Improves COVID-19 Survival in Trial By Reuters Staff 2 minutes (Reuters) - An experimental prostate cancer drug improved the survival of hospitalized COVID-19 patients in Brazil in a clinical trial, researchers reported on medRxiv ahead of peer review. The drug, proxalutamide being developed by Kintor Pharmaceuticals, blocks the effects of androgen hormones by inactivating their receptors on cell surfaces. Before the spikes on the surface of the coronavirus can break into cells and infect them, they must be "primed" by a protein called TMPRSS2, which is regulated by androgen receptors, explained study co-author John McCoy of Applied Biology Inc in an email to Reuters. In the Brazil trial, 645 hospitalized COVID-19 patients who were breathing on their own received either proxalutamide f

Lower salvage radiation dose — are outcomes the same? | THE "NEW" PROSTATE CANCER INFOLINK prostatecancerinfolink.net Lower salvage radiation dose — are outcomes the same? 6-8 minutes A large randomized clinical trial,  SAKK 09/10 , found that a salvage radiation dose of 64 Gy over 32 treatments had equivalent biochemical outcomes compared to 70 Gy over 35 treatments. They treated 350 patients from 2011 to 2014 at 28 hospitals in Germany, Switzerland, and Belgium. The patients were treated with either 3D-CRT (44 percent) or more modern radiation techniques. None had positive lymph nodes. Key patient characteristics were as follows: Biochemically recurrent after prostatectomy (median PSA = 0.3 ng/ml) Positive margins in 45 percent Gleason score ≥ 8 in 18 percent No detectable tumors After 6.2 years of follow-up, outcomes were as follows: Freedom from biochemical progres

Patient-Reported Quality of Life During Prostate Cancer Radiation Therapy: Insights Into the Patient Experience - International Journal of Radiation Oncology, Biology, Physics

Patient-Reported Quality of Life During Prostate Cancer Radiation Therapy: Insights Into the Patient Experience - International Journal of Radiation Oncology, Biology, Physics : As early detection and treatment advances have optimized control and survival for localized prostate cancer, the emphasis has shifted toward managing the toxicity incurred during treatment. One measure of this toxicity is health-related quality of life (HRQOL), which is now frequently employed as a primary endpoint on large cooperative group prostate cancer clinical trials (eg, NRG RTOG 0938, NRG GU-005, PARTIQoL). Patient-reported outcomes (PROs) are the gold standard for reporting HRQOL because they are less prone to physician bias.

Biomarkers Pinpoint Resistant Prostate Cancer That May Benefit From Addition of Apalutamide

Biomarkers Pinpoint Resistant Prostate Cancer That May Benefit From Addition of Apalutamide medscape.com Biomarkers Pinpoint Resistant Prostate Cancer That May Benefit From Addition of Apalutamide By Marilynn Larkin 5-6 minutes NEW YORK (Reuters Health) - Biomarkers can be used to identify patients with prostate cancer refractory to first-line androgen deprivation therapy (ADT) who might benefit from the addition of apalutamide to standard treatments, researchers say. "Patients with a high Decipher (genomic test) score clearly benefit the most from the addition of apalutamide to standard treatments," Dr. Felix Feng of the University of California San Francisco told Reuters Health by email. "Moreover," he said, "patients with the basal subtype of prostate cancer should be selected for further intensification of therapy beyond apalutamide, in clinical trials.&quo
