Abstract: Colorectal cancer (CRC) is the third most prevalent and second deadliest cancer worldwide. This prospective cohort study established patient-derived CRC organoids (75% success rate) and tumor-infiltrating lymphocytes (TILs, 87.5% success rate) as preclinical models for therapy prediction. Targeted NGS sequencing revealed TP53, APC, and KRAS as the most frequent mutations; MSI was detected in 11% of patients. Organoid-TIL co-culture enables exploration of the tumor microenvironment and immune evasion mechanisms, supporting personalized immunotherapy strategies.
