New blood test may someday help guide the best treatment for aggressive prostate cancer

Tumors that spread, or metastasize, in the body shed cells into blood that doctors can scrutinize for insights into what a patient’s cancer might do. Analyzing these so-called circulating tumor cells (CTCs) isn’t part of routine care yet, in part because they’re so hard to pick out of the millions of normal cells in a blood sample. Still, scientists are making progress in this area. And in June, a research team reported that treatment decisions made on the basis of CTC testing had increased lifespans in men with an aggressive type of metastatic prostate cancer. Doctors usually treat metastatic prostate cancer with drugs that interfere with how a man’s body makes or uses testosterone, which is the male hormone (or androgen) that accelerates the tumor’s spread. If the standard hormone-blocking treatments aren’t effective, then doctors have two other options: they can either give chemotherapy drugs known as taxanes, or shift to other hormone blockers that act specifically on the cancer cell’s androgen receptor. Known as androgen receptor signaling (ARS) inhibitors, these alternative hormone blockers include an agent called enzalutamide and another called abiraterone. But neither of them will work if the androgen receptor has a genetic mutation called AR-V7 that also makes the tumors grow very aggressively. With mounting evidence showing that the mutation doesn’t affect a man’s response to taxanes, researchers began to wo...

RARITAN, NJ, May 13, 2020 – The Janssen Pharmaceutical Companies of Johnson &Johnson announced today results from the final analysis of the pivotal Phase 3 SPARTAN study demonstrating ERLEADA® (apalutamide) in combination with androgen deprivation therapy (ADT) significantly improved overall survival (OS), compared to ADT alone, in patients with non-metastatic castration-resistant prostate cancer (nmCRPC) who were at high risk of developing metastases.[i] Results will be presented at the American Society of Clinical Oncology (ASCO) Virtual Scientific Program (Abstract #5516) beginning May 29th. ERLEADA® i...

AbstractStandard therapy for metastatic small cell carcinoma of the prostate (SCCP) remains undefined. We have effectively treated relapsed SCCP with amrubicin. A 72-year-old patient, diagnosed with T4N1M0 prostate cancer, started hormonal therapy in May 2012, elsewhere, and his prostate-specific antigen levels remained low. However, pulmonary and hepatic metastases occurred; high neuron-specific enolase levels suggested SCCP, which was confirmed by repeated biopsy at our institution. In October 2016, chemotherapy with irinotecan and cisplatin was initiated for metastases to the lung, liver, and left pelvic lymph nodes, an...

Treatments for prostate cancer are always evolving, and now research is pointing to new ways of treating a cancer that has just begun to spread, or metastasize, after initial surgery or radiation. Doctors usually give hormonal therapies in these cases to block testosterone, which is a hormone that makes the cancer grow faster. But newer evidence shows that treating the metastatic tumors directly with radiation can produce better results. In March, researchers published the latest study that supports this approach. Based at Johns Hopkins University School of Medicine in Baltimore, the team used a method for delivering power...

(Institute of Cancer Research) A drug already licensed for the treatment of breast and ovarian cancers is more effective than targeted hormone therapy at keeping cancer in check in some men with advanced prostate cancer, a major clinical trial reports.Olaparib, a pill lacking the side effects of chemotherapy, can target an Achilles heel in prostate cancers with a weakness in their ability to repair damaged DNA.

iot S, Pasquier D Abstract Prostate cancer is a sensitive adenocarcinoma, in more than 80% of cases, to chemical castration, due to its hormone dependence. Locally advanced and/or high-risk cancer is defined based on clinical stage, initial prostate specific antigen serum concentration value or high Gleason score. Hormone therapy associated with radiation therapy is the standard of management and improves local control, reduces the risk of distant metastasis and improves specific and overall survival. Duration of hormone therapy, dose level of radiation therapy alone or associated with brachytherapy are controvers...
