Important clarification from the ASCO Living Guideline for #mCRPC: #PSMA PET positivity is an eligibility criterion for 177Lu-PSMA-617, not a basis to exclude radium-223 or other PSMA-independent therapies. Full Article here: doi.org/10.1200/JCO-26-01001

Systemic Therapy in Patients With Metastatic Castration-Resistant Prostate Cancer @ASCO Guideline Update ascopubs.org/doi/full/10.120… The updated ASCO guideline provides evidence-based recommendations for the systemic treatment of patients with metastatic castration-resistant #ProstateCancer (mCRPC). Therapeutic options with demonstrated overall survival benefit include androgen receptor pathway inhibitors (ARPIs), 💊PARP inhibitors, chemotherapy (docetaxel, cabazitaxel), radiopharmaceuticals ☢️(radium-223, 177Lu-PSMA-617), and sipuleucel-T. For patients with BRCA1/2 alterations, ARPI–PARP inhibitor combinations or PARP inhibitor monotherapy are recommended based on prior treatments. Continued androgen-deprivation therapy, early somatic genetic testing, 🦴bone-protective agents for patients with bone metastases, and palliative care are advised. Treatment selection should be guided by prior systemic therapies, although optimal sequencing remains unclear. @RohanGarjeMD @IrbazRiaz @SyedArsalanN @BryanRumble @TiansterZhang @katy_beckermann @NehaVapiwala @sebastienhotte @arnabguonc @AlanBryce9 @lisabodei @DrAndrewLoblaw @HamidEmamekhoo @thomashopemd @M_Hassan_Murad @hongfangliu Ping @Silke_Gillessen @AOmlin @nataliagandur @bavilima

2/4: 👉 Responses that are concordant between the two LLMs (GPT-4-turbo, Claude-3-opus) are more likely to be accurate than the individual LLMs. 👉 In instances of discordance, cross-critique is likely to improve concordance
