#SITC25 Following positive final OS of HARMONi-A: #ivonescimab +chemo post osimertinib in EGFR+ #lungcancer presented by @LeXiuning ▶️ mOS 16 vs 14 mos ( HR 0.74 p=0.019) 👉🏽 first IO/VEGF therapy w survival advantage in EGFR+ 👉🏽is it due to the VEGF or the PD1 inhibition? 👉🏽

Review in JAMA on lung cancer in patients with no smoking history, who now make up about 20% of all new cases of lung cancer. The biology of these cancers is different, as is the treatment, but the gravity is the same. Read now at @JAMA_current. https://t.co/zQhQh7AJSs

We will face a shortage of oncologists as projected cancer cases rise and number of oncologists decreasing relative to demand. 25% of oncologists are 64y and older. Number of oncologists currently on pace to meet only 29% of demand in next 12 years. Gaps will widen.

Preclinical data show that high-dose sucralose reshapes the microbiome, depletes arginine & impairs CD8+ T cells, reducing anti–PD1 efficacy. In 157 patients with melanoma and NSCLC, intake >0.16 mg/kg/d was linked to 2–3x worse survival. 1/2 https://t.co/zdPBI755ti @OncoAlert

Sugary drinks fuel CRC metastasis 🥤 Preclinical data: glucose + fructose activate SORD, alter metabolism (NAD⁺/NADH & mevalonate) ↑ migration/invasion. SORD is elevated in CRC, emerging as biomarker and therapeutic target. https://t.co/xoss8WVEPu @OncoAlert
