In selected fit patients, modified FOLFIRINOX may address mixed phenotypes...Research priorities include ampulla-enriched umbrella trials, explicit AC subcohorts in tissue-agnostic studies, and ctDNA-informed endpoints. This lineage-first, mutation-fast paradigm supports precision care and evidence generation in AC.

Integrating molecular tools and standardized reassessment strategies can enhance HER2 testing reliability and enable more precise treatment strategies, with the potential to minimize HER2 resistance mechanisms. This review provides a practice-oriented guide on the interpretation and optimization of HER2 testing in gastric cancer, while providing insight into the underlying molecular mechanisms driving heterogeneity and resistance.

Mixed and mixed-feature carcinomas share origins with pure endometrial serous and endometrioid carcinoma subtypes but exhibit distinct molecular alterations. These findings highlight the importance of molecular subtyping for diagnosis and treatment planning. Future research could focus on larger cohorts and targeted sequencing to better understand the pathogenesis of mixed and mixed-feature carcinomas in order to refine therapeutic strategies.

The patient received first-line osimertinib combined with pemetrexed/cisplatin, achieving durable disease control for 17 months...Treatment was switched to alectinib, leading to significant tumor regression and partial response. This case illustrates that in triple-positive NSCLC, initial EGFR-TKI combined with chemotherapy can achieve long-term control, while dynamic molecular profiling at progression is essential for identifying resistance mechanisms. Sequential targeted therapy guided by NGS remains a cornerstone for precision management in this complex molecular subtype.

Standardized molecular testing strategies will be key to enable the integration of more consistent and comparable genomic datasets across studies. Further, by elucidating the prognostic relevance of individual genomic alterations, our insights carry significant implications for interpreting single-arm clinical trials within genomically stratified patient cohorts and underscore the importance of randomized studies to delineate the benefit of targeted therapies.

The combined data indicate that ErbB2, perhaps by driving micronuclei formation, has immunogenic properties that manifest in the form of increased T-cell infiltration and expansion, which can be exploited therapeutically by combining PD1-directed checkpoint blockade with ErbB2-targeted therapy.

Combining PD-1 or PD-L1 inhibitors with chemotherapy compared to chemotherapy alone before breast cancer surgery improves pathological response, EFS, and OS in early TNBC. In contrast, the combination of PD-1/PD-L1 inhibitors with chemotherapy after breast cancer surgery may have little to no effect on EFS and OS in early-stage TNBC when compared with chemotherapy alone. The addition of PD-1 or PD-L1 inhibitors probably increases immune-related SAEs.

Postoperatively, the patient received 4 cycles of docetaxel and epirubicin (TE) chemotherapy and is currently taking tamoxifen with no recurrence or metastasis during follow-up. Its rare mixed histological phenotype enriches MBC case literature and provides a reference for the diagnosis and treatment of special subtypes. It also calls for enhanced public education on male breast health, development of gender-specific precise diagnostic and therapeutic strategies, and clinicians' attention to patients' stigma with targeted psychological counseling to reduce diagnostic delays.
