The oncology KOL conversation on X today is led by Lung Cancer, Breast Cancer, GI Cancers, GU Cancers, Multiple Myeloma, Leukemia & Lymphoma. The KOL Pulse Daily Digest of what verified physician (KOL) voices are discussing on X across lung, breast, GI, GU, multiple myeloma, and leukemia & lymphoma, ranked by engagement over the last 48 hours.
The thoracic oncology community is discussing early data for a new first-line combination in KRAS G12C NSCLC. A study of the FAK inhibitor ifebemtinib plus the KRAS G12C inhibitor garsorasib showed a response rate of 82% and a median PFS of 22.3 months. There is also discussion around the expanding role of ADCs, emphasizing the need to assess HER2 and c-Met protein expression at initial diagnosis.

The oral formulation also resulted in less neuropathy. Other conversations include the potential for Anti-Müllerian Hormone (AMH) to predict chemotherapy benefit in premenopausal patients and the clinical integration of SERDs.

With perioperative enfortumab vedotin + pembrolizumab now FDA-approved for muscle-invasive bladder cancer, the GU community's discussion has shifted to next steps — patient selection and whether bladder-preservation strategies can build on the regimen. (The approval itself led yesterday's digest.)

“A few months after ASCO GU, EVP is now FDA approved for cisplatin-eligible MIBC! 🎉 Now many trials looking at bladder preservation in pts w/ cCR inc:”

(The subcutaneous isatuximab on-body injector approval led yesterday's digest.)

“Rapid peak cilta-cel expansion is associated with delayed neurotoxicity (DNT) in myeloma; peak ALC ≥3000/uL, or ≥2500/uL following a daily twofold increase, predicted elevated DNT risk (sensitivity 81%, specificity 59%)”

Conversations highlighted advances in menin inhibitors and the upcoming RAVEN study for newly diagnosed KMT2Ar AML. Other key topics included clinical updates in BPDCN and a review of CAR-T and systemic treatment options for relapsed/refractory DLBCL.
