Tumor immune status was assessed using an immune cell score (ICS), derived from CD3<sup>+</sup> and CD8<sup>+</sup> T-cell densities measured at the invasive margin and tumor core of resected specimens.

Its prognostic/predictive role in terms of benefit from anti-EGFR/bevacizumab (bev) is debated. Similarly, the role of activating HER2 mutations (mut) is unclear.METHODSWe collected individual data of 1,604 patients with proficient mismatch repair (pMMR)/microsatellite stable (MSS) RAS/BRAF wild-type untreated mCRC with HER2 amplification/expression status available enrolled in eight randomized clinical trials (RCT; TRIBE2, TRIPLETE, VALENTINO, ATEZOTRIBE, PANDA, PANAMA, PARADIGM, and CALGB/SWOG80405). Objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) were assessed with respect to HER2 amplification/expression and HER2 mutational status and according to biologics (anti-EGFR/bev).RESULTSPatients with HER2-pos were 81 (5%). HER2-pos patients experienced shorter PFS (median PFS [mPFS]: 9.8 v 12.2 months, hazard ratio [HR], 1.31, P = .02) and OS (median OS [mOS]: 28.0 v 34.9 months, HR, 1.37, P = .01), also after adjustment for covariates (PadjPFS = .02, PadjOS = .048). ORR was similar between HER2-pos and HER2-negative (HER2-neg) tumors (75% v 72%, odds ratio [OR], 1.21, P = .47). We found no interaction between HER2 amplification/expression status and biologics' effect in terms of PFS (Pint = .76), OS (Pint = .76), and ORR (Pint = .64). In left-sided HER2-pos tumors, outcomes were similar with chemotherapy plus bev/anti-EGFRs in terms of PFS (9.8 v 9.3 months, HR, 0.73, P = .29), OS (29.8 v 28.0 months, HR, 1.29, P = .40), and ORR (59% v 79%, OR, 0.39, P = .10). HER2-mutant tumors (2% of patients with HER2-neg tumors) showed shorter OS than HER2 wild-type ones (mOS: 23.7 v 34.4 months, HR, 1.56, P = .04) with no differential effect of biologics (PintORR = .81; PintPFS = .95; PintOS = .92).CONCLUSIONTo our knowledge, this is the largest analysis of HER2 status in patients with untreated mCRC enrolled in RCT. Waiting for targeted approaches, HER2-pos and mut do not predict benefit from bev/anti-EGFRs and should be regarded as negative prognostic factors in pMMR/MSS RAS/BRAF wild-type mCRC.","PeriodicalId":15384,"journal":{"name":"Journal of Clinical Oncology","volume":"23 1","pages":"JCO2501003"},"PeriodicalIF":45.3,"publicationDate":"2025-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144995884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pazopanib, an oral multikinase inhibitor with activity against vascular endothelial growth factor receptor (VEGFR)-2 and -3, PDGFR-alpha and-beta, and c-Kit, was tested for efficacy in epNET.PATIENTS AND METHODSWe conducted a multicenter, randomized, double-blind, phase II study of pazopanib (800 mg once daily) versus placebo in low- to intermediate-grade epNET with radiologic progressive disease (PD) within 12 months of study entry. Previous somatostatin analog (SSA) was required for midgut tumors, and concurrent SSA was allowed. The primary end point was progression-free survival (PFS) by blinded independent central review. Unblinding and crossover were allowed if PD was confirmed by central review.RESULTSOne hundred seventy-one patients (97 pazopanib and 74 placebo) were randomly assigned between September 2013 and October 2015. The majority had a midgut primary site (75%) and previous SSA treatment (93%). About half (49%) of the patients had functional tumors. The median follow-up was 61 months (95% CI, 60 to 63). Median PFS was 11.8 versus 7.6 months in pazopanib versus placebo, respectively (hazard ratio, 0.54 [95% CI, 0.37 to 0.79]; P < .001); 49 placebo patients crossed over to pazopanib. There was no significant difference in overall survival between the treatment arms. Rates of grade 3 or greater adverse events (regardless of attribution) were higher in pazopanib versus placebo (84% v 47%; P < .001), as were grade 5 death events (8% v 0%, P = .017).CONCLUSIONPazopanib compared with placebo significantly improves PFS in patients with progressive epNET, confirming that the VEGF signaling pathway is a valid target for therapy in epNET. However, after integrating the associated risks relative to the benefits, further development of pazopanib in this clinical context is not planned.","PeriodicalId":15384,"journal":{"name":"Journal of Clinical Oncology","volume":"46 1","pages":"JCO2402644"},"PeriodicalIF":45.3,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144960096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
