Review of combination strategies for digestive system tumors including gastric and colorectal cancer

This publication is a review that aims to offer a theoretical foundation and strategic directions to overcome clinical drug resistance and advance precision oncology. It covers a broad scope of digestive system tumors, specifically including gastric cancer, colorectal cancer, and hepatic malignancies. The text explores various intervention approaches such as immunochemotherapy, oncolytic virus, targeting of cancer stem cells, epigenetic modulation, and nanoparticle-based drug delivery systems alongside standard chemotherapy and immune checkpoint inhibitors. No specific sample size, setting, or follow-up duration was reported for these theoretical considerations.

The authors synthesize arguments regarding the potential of these combination strategies but emphasize that the underlying mechanisms remain incompletely understood. Consequently, the review does not provide pooled effect sizes or specific adverse event rates, as these details are not reported in the source material. The discussion focuses on the conceptual landscape of advancing therapeutic options rather than presenting data from a specific clinical trial.

Limitations acknowledged by the authors include the fact that strategies to further enhance the efficacy of combination therapies are still lacking. The review concludes that while these approaches provide a theoretical basis, their practical application requires further investigation. The practice relevance is framed as offering strategic directions rather than establishing new clinical guidelines based on definitive efficacy data.
