Aim: Currently, the primary method for assessing the prognostic differences among patients is the tumor-node-metastasis (TNM) staging system developed by the American Joint Committee on Cancer (AJCC). Our aim was to evaluate the incidence of the presence of pericolonic tumor deposits in patients operated on for colorectal cancer, and to demonstrate its relation with tumor stages. Materials and Methods: The pathological findings of a total number of 190 patients who underwent surgical resections for colorectal cancer were evaluated retrospectively. Staging was carried out according to the 7th edition of the AJCC staging manual. Results: Among all 190 colorectal cancer patients, a total of 30 (15.8%) patients were detected to harbor pericolonic tumor deposits. In the final pathology reports, 66.6% of the patients were reported as T3, and 46.6% were reported as N1c. Thus, 56.6% of the patients were reported as Stage IIIB. Discussion and Conclusion: In the absence of other evidence of lymph node involvement, the presence of pericolonic tumor deposits results in the reclassification of the disease from StageII to Stage III. The fact that Stage III disease necessitates adjuvant treatment puts forth an emphasis on the importance of upstaging due to the presence of tumor deposits.
