Unlike SOLO-1 or PAOLA-1, PRIMA included both HRD-positive and HRD-negative patients — and many in the control arm later received PARP inhibitors (~40–50%). Result: PFS & QoL benefits persist, but no OS separation. The message? 🔬 HRD testing still matters. #Oncology #PARP

Quitting smoking after a cancer diagnosis isn’t “too late.” Even in stage III–IV, stopping within 6 months boosts 2-year survival from 74.7% → 85.1%. That’s nearly double the mortality risk if you keep smoking (aHR 1.97). Smoking cessation should be the 4th pillar of cancer

Precision surgery in cervical cancer, backed by evidence. The PHENIX trial (NEJM 2025) shows that Sentinel lymph-node biopsy (SLNB-only) is non-inferior to pelvic lymphadenectomy for 3-year DFS — while reducing lymphedema, lymphocele, and pain by 3–4×. Minimal harm, maximal

Actionable genetic alterations now define modern oncology. From tumor-specific targets like ALK, EGFR, KRAS to tumor-agnostic biomarkers such as MSI-H, NTRK, RET, HER2 IHC3+, and BRAF V600E — this is precision medicine, 2025 edition. 🧬✨ #Oncology #PrecisionMedicine #FDA

Combining precision with consolidation. At #ESMO25 (LBA72), the NorthStar trial shows that adding local consolidative therapy (LCT) to osimertinib extends PFS by 34% in EGFR-mutant NSCLC (25.3 vs 17.5 mo, HR 0.66, p=0.025). A chemo-free, tolerable path for oligometastatic

From routine imaging to predictive insight! At #ESMO25 (Abstract 1080), a deep-learning analysis reveals that thymic health on standard CT scans can forecast immunotherapy response across cancers. Higher thymic health = ↓ risk of progression (HR 0.65) & ↓ mortality (HR 0.56),

Two paths emerging for ES-SCLC maintenance after chemo-immunotherapy. The DeLLphi-303 study explores DLL3-directed T-cell engagement (tarlatamab + PD-L1), while a phase II trial tests ATR inhibition (ceralasertib + durvalumab) to enhance immune persistence. #ESMO25 #SCLC

Not all PSMA-positive patients are the same.; In PSMAddition, adding Lu-177 to ADT + ARPI modestly delayed progression but didn’t improve OS — and patient-reported QoL was slightly worse. Upfront use remains experimental until mature survival and biomarker-based subgroup data
