摘要 Abstract

Background: RET fusions occur in ~1-2% of advanced NSCLC (aNSCLC). Selective RET inhibitors (SRIs) significantly improve outcomes, yet ~10% of patients progress by 6 months and ~30% by 12 months. Predictors of response or early progression remain poorly defined. Methods: A multicenter retrospective analysis (RET-MAP) of RET+ aNSCLC from 47 international centers evaluated clinical/genomic correlates of SRI outcomes. Multivariable Cox models estimated progression-free (PFS) and overall survival (OS) and tested interactions with first-line (1L) SRI versus chemotherapy ± immune checkpoint inhibitor (CH±ICI). In parallel, genomic/transcriptomic features were characterized in an external Caris Life Sciences (CLS) RET+ aNSCLC cohort. Results: Among 510 RET-MAP patients (median age 63; 59% female; 36% ever-smokers; 92% adenocarcinoma), 401 received an SRI (1L n=151; later lines n=250). Median PFS on SRI (any line) was 17.1 months (95% CI, 14.5-21.1), median OS 30.4 months (95% CI, 27.0-41.1). TP53 co-mutation was present in 27% (78/292 tested) and was associated with shorter PFS (8.9 vs 19.2 months; p<0.001) and OS (22.7 vs 30.9 months; p=0.002), without a significant treatment-by- TP53 interaction for 1L SRI versus CH±ICI (p=0.22). Fusion partner contributed with additional signal: KIF5B (73%, 274/373) had inferior PFS (13.4 vs 60.2 months; p<0.001) and OS (26.6 vs 73.0 months; p=0.002) compared with CCDC6 (17%, 65/373), and a significant treatment-by-fusion interaction favored SRI over CH±ICI in CCDC6 versus KIF5B (p=0.007). On multivariate analysis, shorter PFS and OS were independently associated with TP53 mutation (HR 1.74, p<0.001; HR 1.77, p=0.001), KIF5B fusion (HR 1.98, p=0.002; HR 1.64, p=0.040), ECOG ≥2 (HR 2.20, p<0.001; HR 3.06, p<0.001), and brain metastases (HR 1.59, p=0.003; HR 1.88, p<0.001); worse OS was associated with non-adenocarcinoma histology (HR 1.74, p=0.049) and smoking (HR 1.42, p=0.034). Notably, KIF5B fusions were enriched for TP53 mutations versus CCDC6 (40% vs 19.6%, p=0.011), suggesting partially overlapping biology. In the CLS cohort (N=211), TP53 -mutant tumors (74/211) were enriched for RB1 mutations, had higher PD-L1 expression and tumor mutational burden, and demonstrated increased M1 macrophage/B-cell infiltration with reduced neutrophils; by fusion partner, CCDC6 showed higher PD-L1, while global transcriptomes were otherwise similar to KIF5B . Conclusions: In RET+ aNSCLC, TP53 mutation is prognostic for inferior outcomes on SRIs but not predictive of differential benefit versus CH±ICI. Fusion partner carries both prognostic and predictive relevance; CCDC6 is associated with a more indolent course and greater relative benefit from SRI. External profiling supports an inflammatory microenvironment in TP53 -mutant disease, reinforcing biologically distinct-and clinically meaningful-subsets within RET -driven lung cancer.
