The study aimed to analyze the expression of several genes and proteins related to colorectal cancer in Tibetan patients, specifically SMARCA4, BRAF, P53, PD-1, and PD-L1, to inform targeted and immunotherapy options.
Researchers included 64 colorectal cancer patients from a local hospital, investigating tumor characteristics like location, type, and gene mutations using techniques such as immunohistochemistry and PCR.
Results showed a predominance of adenocarcinomas, with the majority of patients in advanced cancer stages, revealing varied expression levels of key proteins and a notable presence of P53 mutations, while no gene fusions involving NTRK were found.
