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.
A clinical validity study published in Clinical Cancer Research found that landmark ctDNA molecular response is an early predictor of immunotherapy outcomes in lung cancer. Additionally, discussion is highlighting the role of antibody-drug conjugates (ADCs) in treating patients with lung cancer and brain metastases, focusing on recent data and guideline recommendations.

Separately, data from the WSG ADAPT-HR+/HER2− and ADAPTcycle trials showed low post-endocrine Ki67 levels are associated with improved outcomes, helping optimize patient selection for chemotherapy omission. Additionally, ctDNA was noted to be superior to tumor tissue biopsy for detecting acquired ESR1 mutations in metastatic HR+ disease.

The design for the phase 3 LUCERNA trial was also shared, evaluating zolbetuximab with pembrolizumab and chemotherapy in CLDN18.2+, HER2-, PD-L1+ gastric/GEJ cancer. Additionally, the first patient was dosed in a trial of an off-the-shelf therapeutic vaccine for esophageal cancer.

“First-line disitamab vedotin + tislelizumab + S-1 showed impressive activity in HER2-overexpressing advanced gastric/GEJ adenocarcinoma @JCO_ASCO • ORR 89.5% • mPFS 13.8 mo • mOS 31.9 mo”

Clinical commentary highlights the risk of urothelial cancer recurrence in the urethra post-cystectomy, even with negative washings or imaging. Other areas of focus for the GU oncology community include prostate cancer survivorship, specifically the neurocognitive effects of Androgen Deprivation Therapy (ADT) and lifestyle interventions, alongside discussions on the appropriate use and limitations of AI in kidney cancer research.

Separately, a study in Blood Cancer Journal found that high WEE1 expression is independently linked to poor survival. The myeloma/hematology community is also sharing clinical guidance on the treatment of plasma cell leukemia, as published in Blood.

Separately, a systematic review is focusing on asciminib as a first-line therapy in chronic myeloid leukemia, and a multicenter retrospective study evaluated upfront autologous stem cell transplantation in first complete remission for advanced-stage extra-nodal NK/T-cell lymphoma.
