Additionally, the proportion of deficient mismatch repair that developed into microsatellite instability-high was observed to be lower in the left-sided CRC compared to the right-sided, indicating divergent DNA damage repair systems between laterality subtypes that contribute to differential immunotherapy efficacy. This integrated proteogenomic study provides a comprehensive and nuanced understanding of the molecular heterogeneity between left- and right-sided CRC, offering opportunities for optimizing these patients' treatment outcomes through tailored therapeutic strategies.

Integrated profiling of TETs reveals distinct genomic, transcriptomic, and immune features across subtypes of TETs and identifies potentially actionable therapeutic targets that may inform future treatment strategies.

Minimal microsatellite shift is commonly detected in MSI-H cases, and some cases are difficult to interpret due to their classification within the equivocal range. Increasing the number of microsatellite loci, combined with visualization graph comparison and integration of mismatch repair protein immunophenotype and histological features, can effectively improve the accuracy of MSI-H interpretation.

ICI rechallenge in GC should be regarded as a biomarker-informed investigational strategy rather than a standard of care. Prospective trials, standardized definitions, validated biomarkers, and careful toxicity monitoring are needed.

YORC presents more often with symptoms and advanced disease (M+, N+, EMVI+), yet short-term survival in non-metastatic patients tended to parallel that of older individuals. These findings underscore the need for earlier diagnosis, tailored management, and increased clinical awareness.

Colorectal cancer treatment is increasingly evolving into a precision oncology approach. Integration of molecular biomarkers enables tailored therapy decisions and opens new options, particularly in adjuvant and metastatic settings.

BRAF and RAS mutation occurred in 60% and 14% of the patients with available molecular data, respectively. No patients harbored HER2 amplification, suggesting that the co-occurrence of HER2 amplification and dMMR/MSI is essentially anecdotal, making therefore HER2 testing in this subgroup less compelling.

Molecular classification provides clinically meaningful information beyond traditional histopathologic factors and is closely associated with the risk of lymph-node metastasis in endometrial cancer. The consistently low nodal involvement observed in POLEmut and the high risk observed in p53abn support a more tailored approach to surgical staging.
