The oncology KOL conversation on X today is led by Lung 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.
Thoracic oncologists are working through the fine print of the TREASURE trial — @jryckman3 flagged its very large treatment volumes (mean PTV 460 cc, on par with the ~460 cc median in the definitive PACIFIC-2 NSCLC trial). Alongside the trial talk, @NarjustFlorezMD opened a discussion on lifestyle medicine in lung cancer, and @Joshua_Reuss announced an interesting upcoming session at #DCLung26 on best practices in unresectable NSCLC (presented by @NitikaPaudel).

“Another important TREASURE detail: the mean PTV was 460 cc. For scale, PACIFIC-2, a definitive NSCLC trial, reported a median PTV of approximately 460 cc. These were very large thoracic treatment volumes, even if protocol-concordant, and target volume should be considered when”

Separately, @PTarantinoMD shared a new #JNCI analysis of over 7,000 HR+/HER2- early breast cancer patients (Flatiron), reporting 7-year recurrence rates of 14% in N1 and high-risk N0 disease and up to ~40% in N2-3 — data he frames as support for adjuvant CDK4/6 inhibition.

“Our OPTIMAL trial is now in print in the July 2026 @Annals_Oncology oral paclitaxel (DHP107) is non-inferior to weekly IV paclitaxel in HER2− metastatic breast cancer — same efficacy, less neuropathy, no infusion. Now MFDS-approved in Korea (weekly). #BCSM”

“What is the real-world risk of recurrence from HR+/HER2- EBC? In our latest #JNCI article, including data from >7000 pts (Flatiron) we report 7y recurrence rates of 14% for N1 and N0 high-risk pts and up to ~40% in N2-3, supporting use of adjuvant CDK4/6i.”

Additionally, the Phase 3 PERISCOPE II trial in gastric cancer with limited peritoneal metastases showed no survival benefit for gastrectomy plus cytoreductive surgery and HIPEC versus systemic chemotherapy alone. New Pan-Asian adapted ESMO clinical practice guidelines for HCC were also a topic of conversation.

Other topics include long-term follow-up from the OMNIVORE study in RCC, which found half of patients can remain off-therapy after nivolumab induction, and a post-hoc analysis of ARASENS suggesting age alone should not preclude triplet therapy in mHSPC.

The myeloma/hematology community is discussing the recent FDA approval of an on-body injector (OBI) for Isatuximab, offering a new delivery method for the drug. Additionally, a new Phase 2 randomized trial (EAA241) has been announced to compare Dara-Bor-Dex versus Cy-Bor-Dex in newly diagnosed multiple myeloma patients with light chain cast nephropathy (LCCN), with study activation planned for August 11, 2025.

A study of 38 patients showed a 53% complete response rate and a median duration of response of 27.8 months among responders. Other topics include harmonizing first-line trial design in Large B-cell Lymphoma and leukemia trial highlights from EHA2026, such as OPTI-AML, KOMET-007, and SENTRY.
