Humanized Mice Reveal Role of Immune System in Prostate Cancer Therapy Efficacy - Steven Kregel

Details
Andrea Miyahira hosts Steven Kregel to discuss a published paper on humanized mouse models for metastatic prostate cancer. Dr. Kregel discusses the challenges of modeling prostate cancer in mice and introduces humanized mouse models that better recapitulate human immune responses. He explains how these models, developed using human hematopoietic stem cells, allow for the study of cancer therapies...

Antibody Drug Conjugate FOR46: Targeting CD46 in mCRPC in Phase 1b Trial - Nonna Shakhnazaryan

Details
Nonna Shakhnazaryan discusses a phase 1b dose escalation study of FOR46, a novel antibody-drug conjugate targeting CD46, in combination with enzalutamide for metastatic castration-resistant prostate cancer. The study establishes the maximally tolerated dose and shows promising results, with 71% of patients experiencing PSA declines, including some who previously progressed on enzalutamide. The med...

Extracellular Vesicles in Prostate Cancer: Multi-Omic Liquid Biopsy - Irene Casanova-Salas & Joaquin Mateo

Details
Andrea Miyahira discusses with Irene Casanova-Salas and Joaquin Mateo a Cancer Cell publication on using circulating tumor extracellular vesicles (EVs) to monitor metastatic prostate cancer evolution. The researchers describe their novel method for analyzing both DNA and RNA from EVs in patient plasma samples. They highlight the advantages of EV analysis over traditional ctDNA, including the abili...

NSD2's Role in Prostate Cancer: Uncovering AR's Functional Duality - Abhijit Parolia

Details
Andrea Miyahira interviews Abhijit Parolia about his group's study on NSD2's role in prostate cancer. Dr. Parolia explains how NSD2, a histone methyltransferase, reprograms androgen receptor (AR) activity in prostate cancer cells. The research reveals that NSD2 is upregulated in malignant prostate tissue and is crucial for AR binding to chimeric AR-FOXA1 sites, promoting tumor growth. Using CRISPR...

AI-Powered Prostate Cancer Grading Predicts Active Surveillance Outcomes - Cornelia Ding

Details
Andrea Miyahira interviews Cornelia (Chien-Kuang) Ding about her study on predicting prostate cancer grade reclassification using a deep learning-based grading algorithm. Dr. Ding discusses their evaluation of the AIRAProstate algorithm across two cohorts at Johns Hopkins University. The study reveals that AI-based upgrading of initial biopsies is associated with later grade reclassification in ac...

Cell Surface Targets in mCRPC: Expression Landscape and Therapeutic Potential - Michael Haffner

Details
Andrea Miyahira interviews Michael Haffner about his group's study on the expression of TROP2, CEACAM5, and DLL3 in metastatic prostate cancer, published in NEJM Evidence. Dr. Haffner discusses their analysis of over 750 samples from 52 patients in a rapid autopsy cohort, examining protein expression across different molecular subtypes of castration-resistant prostate cancer. The study reveals dis...

Genomic Alterations and Lutetium PSMA Response in Prostate Cancer - Alexandra Sokolova

Details
Alexandra Sokolova discusses her team's study on genomic alterations influencing the response to lutetium-177 PSMA in metastatic castration-resistant prostate cancer. Their research highlights the need for better biomarkers to predict patient outcomes with lutetium-177 PSMA, as not all patients respond to this treatment. Utilizing data from a collaborative database of over 2000 patients, Dr. Sokol...

PSCA CAR T-Cell Therapy for Metastatic CRPC: Phase 1 Trial Results - Tanya Dorff

Details
Tanya Dorff discusses her team's Phase 1 trial on PSCA CAR T cell therapy for metastatic castration-resistant prostate cancer, published in Nature Medicine. Dr. Dorff highlights that prostate cancer's immunosuppressive environment poses significant challenges, making the development of potent therapies like CAR T cells crucial. The trial involved administering CAR T cells, initially without and th...

BRCA2 and Beyond: Unraveling Genetic Drivers of Prostate Cancer Aggressiveness - Hiba Khan

Details
Andrea Miyahira talks with Hiba Khan about her presentation on germline genetic associations in prostate cancer. Dr. Khan's study, leveraging data from Invitae, explores genetic testing results linked to medical records to identify gene-specific associations and potential disparities in testing among diverse populations. Key findings reveal that BRCA2 is the most common mutation across all demogra...

ctDNA Fraction Predicts Response to Lutetium PSMA in TheraP Trial for mCRPC - Edmond Kwan

Details
Edmond Kwan discusses his latest research on circulating tumor DNA (ctDNA) as a predictive marker for response to Lutetium PSMA-617 versus cabazitaxel. The Phase II TheraP trial compared these treatments in patients with advanced metastatic castration-resistant prostate cancer, utilizing dual imaging selection. Dr. Kwan highlights that ctDNA fraction, the proportion of tumor-derived DNA in circula...
