Personalized dosing improves outcomes for men with metastatic castration-resistant prostate cancer

Personalized dosing improves outcomes for men with metastatic castration-resistant prostate cancer news-medical.net Reviewed by Megan Craig, M.Sc.Jun 26 2023 By monitoring early-response biomarkers in men undergoing 177 Lu-PSMA prostate cancer treatment, physicians can personalize dosing intervals, significantly improving patient outcomes. In a study presented at the Society of Nuclear Medicine and Molecular Imaging 2023 Annual Meeting, early stratification with 177 Lu-SPECT/CT allowed men responding to treatment to take a "treatment holiday" and allowed those not responding the option to switch to another treatment. Approved by the U.S. Food and Drug Administration in 2022, 177 Lu-PSMA is an effective treatment for metastatic castration-resistant prostate cancer. However, not all men respond equally to treatment, with some respond

Novartis confirms unconstrained supply for Pluvicto® and continues to significantly expand the number of treatment centers | Novartis

Novartis confirms unconstrained supply for Pluvicto® and continues to significantly expand the number of treatment centers | Novartis : Pluvicto is an intravenous radioligand therapy (RLT) combining a targeting compound (a ligand) with a therapeutic radionuclide (a radioactive particle, in this case lutetium-177)2,3. After administration into the bloodstream, Pluvicto binds to target cells, including prostate cancer cells that express PSMA, a transmembrane protein2,3. Once bound, energy emissions from the radioisotope damage the target cells and nearby cells, disrupting their ability to replicate and/or triggering cell death3.

“Mind-Blowing” Cancer Discovery – Common Chemotherapy Drugs Don’t Work Like Doctors Thought

“Mind-Blowing” Cancer Discovery – Common Chemotherapy Drugs Don’t Work Like Doctors Thought scitechdaily.com University of Wisconsin-Madison New research challenges the traditional belief about how microtubule poisons, a class of cancer drugs, work. Instead of stopping cancer cells from dividing, these drugs alter the process, sometimes causing new cancer cells to die. The findings provide insights into why certain drug discovery attempts were unproductive and suggest a need to focus on disrupting the cell division process differently. The research uncovers the likely reason why certain chemotherapies are effective for many patients. Importantly, they also shed light on why endeavors to discover new chemotherapy drugs based solely on stopping cellular division have been so disappointing. Recent research from the University of Wisconsin–Madison indicates

Multinational Study Suggests High Variability with Quality of Prostate MRI

Multinational Study Suggests High Variability with Quality of Prostate MRI diagnosticimaging.com Jeff Hall In a study of 355 multiparametric prostate MRI exams from a total of 71 scanners from 41 facilities in 18 countries, researchers found that only 23 scanners achieved a PI-QUAL score of 5 for optimal image quality. Emerging research from a multinational study involving over 40 facilities reveals a significant degree of variability with the quality of imaging for prostate multiparametric magnetic resonance imaging (mpMRI) exams. For the multicenter study, recently published in Radiology , researchers utilized the PI-QUAL scoring system to assess 355 mpMRI exams performed at 41 facilities in 18 countries from September 2021 to August 2022. Out of a total of 71 MRI scanners, the researchers found that only 23 scanners (32 percent) achieved a PI-QUAL score

Docetaxel radiosensitizes castration-resistant prostate cancer by downregulating CAV-1: International Journal of Radiation Biology: Vol 0, No 0

Docetaxel radiosensitizes castration-resistant prostate cancer by downregulating CAV-1: International Journal of Radiation Biology: Vol 0, No 0 tandfonline.com Docetaxel radiosensitizes castration-resistant prostate cancer by downregulating CAV-1 Nrusingh C. Biswal 6–7 minutes Abstract Purpose: Docetaxel (DXL), a noted radiosensitizer, is one of the few chemotherapy drugs approved for castration-resistant prostate cancer (CRPC), though only a fraction of CRPCs respond to it. CAV-1, a critical regulator of radioresistance, has been known to modulate DXL and radiation effects. Combining DXL with radiotherapy may create a synergistic anticancer effect through C

Microultrasound in the detection of the index lesion in prostate cancer - Pedraza - The Prostate - Wiley Online Library

Microultrasound in the detection of the index lesion in prostate cancer - Pedraza - The Prostate - Wiley Online Library onlinelibrary.wiley.com Adriana M. Pedraza MD ORIGINAL ARTICLE Abstract Introduction and Objective The natural progression of prostate cancer is primarily driven by an index lesion (IL) . Studies have shown that different metastases within the same patient arise from a single precursor cell. Therefore, our aim is to assess the effectiveness of transrectal microultrasound (MUS) in comparison to multiparametric magnetic resonance imaging (mpMRI) for detecting the IL in prostate cancer. We used quarter-mount pathological results as the reference standard for this evaluation. Materials an

How this device uses sound waves to destroy tumors | Popular Science Histotripsy is a non-invasive cancer treatment that uses ultrasound to break up tumors in the body. It uses controlled sound waves to create micro-bubbles to destroy the targeted diseased tissue, eliminating the use of radiation, chemotherapy and surgical incisions. It was developed over 20 years ago by Michigan Engineering researchers in collaboration with clinicians @MichiganMedicine and the U-M Rogel Cancer Center, and later brought to clinical use by Minneapolis based company HistoSonics. https://news.engin.umich.edu/2023/10/... After successful clinical trials in Europe and the United States, where the  HistoSonics Edison Platform was used to treat patients with metastatic liver tumors, the Food and Drug Administration has approved the use of histotripsy in hospitals worldwide. With the FDA approval, Histosonics can now sell the Edison Platform to hospitals, giving liver cancer patients a non-invasive treatme
