Abstract

Objectives: To investigate the tumor-infiltrating lymphocytes in invasive margins and the correlation with pathologic features in patients with colorectal cancer. Methods: A cross-sectional descriptive study was conducted on 131 patients diagnosed with colorectal cancer and surgically resected at Military Hospital 103. The tumor samples were processed according to standardized pathological procedures. TILs in the invasive margin were assessed on tumor slides, and their correlation with pathologic features was evaluated. Results: The mean percentage of TILs was 14.96% with a standard deviation of 17.5% and a median of 5%, the higher percentage of TILs was significantly associated with good prognosis pathological factors including tumors with lower tumor stages, low grades, early TNM stages, and non-perineural invasion. Conclusion: The tumor-infiltrating lymphocytes could play a significant prognostic role in patients with colorectal carcinoma.
