Neoadjuvant TQB2102 (Bispecific HER2-Directed ADC) Produces High Pathologic Complete Response Rates in Early and Locally Advanced HER2-Positive Breast Cancer
A randomized phase II trial of the bispecific HER2-directed ADC TQB2102 (n=104) showed robust total pathologic complete response rates (tpCR 57.7–76.9% across cohorts) with manageable grade ≥3 toxicity and no treatment‑related deaths, suppo

Eflornithine Plus Lomustine Extends Progression-Free and Overall Survival in Recurrent IDH‑Mutant Grade 3 Astrocytoma — Results from STELLAR Phase III
The STELLAR phase III trial found that eflornithine added to lomustine doubled PFS and significantly improved OS in patients with recurrent IDH‑mutant grade 3 astrocytoma after radiotherapy and temozolomide, with increased but manageable my

Amivantamab Plus Lazertinib Shows Promising Activity in Atypical EGFR-Mutant Advanced NSCLC: CHRYSALIS‑2 Cohort C Results
In CHRYSALIS‑2 Cohort C, the amivantamab plus lazertinib combination produced a 52% ORR and durable responses (mDoR 14.1 months) in advanced NSCLC with atypical EGFR mutations, with higher activity in treatment‑naïve patients and an expecte

Neoadjuvant TAR-200 (intravesical gemcitabine) plus cetrelimab shows improved pathologic responses and MRD signal utility in cisplatin-ineligible MIBC: Primary SunRISe-4 analysis
SunRISe-4 reports higher pCR, pOR, and 1‑year RFS for neoadjuvant TAR‑200 plus cetrelimab versus cetrelimab alone in cisplatin‑ineligible/refusing MIBC, with urinary and circulating tumor DNA MRD correlating with outcomes.

Atezolizumab Plus Bevacizumab and Chemotherapy in Recurrent Ovarian Cancer: Two Phase III Trials Fall Short of Practice‑Changing Benefit
Two randomized phase III trials tested adding atezolizumab to bevacizumab plus chemotherapy in recurrent ovarian cancer. Neither AGO‑OVAR 2.29/ENGOT‑ov34 (non‑platinum, platinum‑resistant) nor ATALANTE/ENGOT‑ov29 (platinum‑sensitive) met th

Pirtobrutinib Matches and May Surpass Ibrutinib in BTKi‑Naïve CLL/SLL: First Randomized Head‑to‑Head Results with Improved Cardiac Safety
In the first randomized comparison of pirtobrutinib versus ibrutinib in BTKi‑naïve CLL/SLL (N=662), pirtobrutinib met noninferiority for overall response and showed favorable early PFS trends and lower rates of atrial fibrillation and hyper

Postoperative ctDNA Identifies Stage III Colon Cancer Patients Who May Benefit from Adjuvant Celecoxib
A post hoc analysis of CALGB (Alliance)/SWOG 80702 shows postoperative ctDNA positivity strongly predicts recurrence and suggests adjuvant celecoxib improves DFS and OS in ctDNA-positive stage III colon cancer.

Minimally Invasive Pancreatoduodenectomy Is Noninferior to Open Surgery for 90‑Day Complications but Raises Important Safety and Generalizability Questions
An international randomized trial found minimally invasive pancreatoduodenectomy (mostly robotic) noninferior to open surgery for 90‑day overall complications and modestly faster functional recovery, with lower fistula and wound‑infection r

Low‑Dose IL‑2 after Lymphodepletion and TIL Infusion Offers Comparable Immune and Clinical Outcomes to High‑Dose IL‑2 in Metastatic Melanoma
A phase II study in metastatic melanoma found no major differences in response, circulating T‑cell phenotypes, or proliferative signals between high‑dose and low‑dose IL‑2 after lymphodepletion and tumor‑infiltrating lymphocyte (TIL) infusi

A 30-Day Mortality Risk Score After Proctectomy for Rectal Cancer: What the NCDB Tells Us and How to Use It
A validated NCDB-derived risk score using age, sex, race, comorbidity, stage, neoadjuvant therapy, length of stay and conversion identifies patients at markedly different 30-day mortality risk after proctectomy (0.8%–4.5%).

Preoperative Pembrolizumab Plus Chemoradiotherapy (PPCT) for Locally Advanced Resectable ESCC: PALACE‑2 Phase 1/2 Results and Immune‑Microenvironment Insights
PALACE‑2 reports that preoperative pembrolizumab combined with chemoradiotherapy produced a 43.2% pathologic complete response in resectable, locally advanced esophageal squamous cell carcinoma, with acceptable short‑term survival and a hig

Checkpoint inhibition for frail patients: Durvalumab with carboplatin–etoposide shows tolerability and a 1‑year survival signal in poor‑performance‑status extensive‑stage SCLC (NEJ045A)
NEJ045A shows durvalumab plus carboplatin–etoposide is feasible in ES‑SCLC patients with PS2–3, with induction completion rates above thresholds and a 1‑year survival of 43.4% overall, supporting cautious use of chemo‑immunotherapy in selec

Metronomic Capecitabine Gives Durable 10‑Year DFS Benefit in Early Triple‑Negative Breast Cancer — FOXC1 May Identify Who Benefits
A 10‑year follow‑up of SYSUCC‑001 shows 1 year of metronomic capecitabine after standard adjuvant therapy improved disease‑free survival in early triple‑negative breast cancer; FOXC1 expression emerged as a potential predictive biomarker in

Distant Disease‑Free Survival Is a Reliable Surrogate for Overall Survival in Most Neoadjuvant Early Breast Cancer Trials — but Not All Subtypes
A pooled individual‑patient analysis of 11 neoadjuvant RCTs (12,247 patients) finds distant disease‑free survival (DDFS) strongly predicts overall survival (OS) trial‑level effects overall (R2trial=0.91), with weakened surrogacy in hormone‑

Camrelizumab plus Rivoceranib Delivers Substantial Survival Gain over Sorafenib in First‑line Unresectable HCC: Final CARES‑310 Results
Final CARES-310 analysis shows camrelizumab plus rivoceranib significantly improves overall survival versus sorafenib in first-line unresectable hepatocellular carcinoma, with increased but manageable toxicity. Results support the combinati

Total Neoadjuvant Therapy Enables Organ Preservation Without Compromising Distant Control in pMMR/MSS Stage II–III Rectal Cancer: Insights from the NO-CUT Trial
The NO-CUT phase 2 trial shows that total neoadjuvant therapy (CAPOX-based TNT) followed by non-operative management for clinical complete responders achieved high 30‑month distant relapse‑free survival (95%) and enabled organ preservation

A Standardized RANO Resection Classification Links Supramaximal Surgery to Meaningful Survival Gains in IDH‑Mutant Grade 2 Glioma
An international retrospective cohort (n=1,391) validates a four‑tier RANO classification of residual T2‑FLAIR volume: supramaximal resection confers the largest survival benefit, with graded, durable advantages for maximal versus submaxima

Microbubble‑Enhanced Focused Ultrasound with Temozolomide Shows Feasibility and Promising Survival in High‑Grade Glioma — Phase 1/2 Multicentre Results
A multicentre phase 1/2 trial reports that MRI‑guided microbubble‑enhanced transcranial focused ultrasound (MB‑FUS) can safely open the blood–brain barrier and be combined with standard adjuvant temozolomide in high‑grade glioma, with media

Pembrolizumab plus Lenvatinib Shows Promising Activity but Substantial Toxicity as Second-Line Therapy After Nivolumab–Ipilimumab in Pleural Mesothelioma
