Özet

Results: A total of 20 patients were included in this study and were divided into the DLBCL (n=5), MM (n=4), MC (n=3), and NET (n=8) groups. The emergency application rate (60%) was the highest in the DLBCL group (P=0.004). The mean age of the patients was above 50 years in all groups, and there was no difference among groups in this regard (P=0.966). The mean tumor diameter values were 8, 6.55, 5.4, and 3.75 cm, respectively (P=0.73) in the groups. Furthermore, the numbers of lymph nodes dissected were 13, 14.5, 19, and 19, respectively (P=0.373), and the numbers of metastatic lymph nodes were determined at 0 ,1.5, 0, and 0.5, respectively (P=0.188). The survival rate was significantly the shortest in the MM group, and the longest survival rate was noted in the NET group (15.625, 8.5, 20, 40.857, respectively; P=0.001).

Methods: A total of 1100 patients were applied for surgical treatment due to colorectal cancer at a general surgical clinic between 2010 and 2020. The selected patients were divided into four groups of Diffuse large B-cell lymphoma (DLBCL), Malignant melanoma (MM), Medullary carcinoma (MC), and Neuroendocrine tumor (NET). Following that, clinicopathological data of patients and their survival periods have been compared in this study.

Background: A majority of colorectal neoplasms are adenocarcinomas; however, there is a small percentage of tumors from other histological cell lines.


Conclusion: Although clinicopathological features and postoperative follow-up results were similar, there were differences in the survival rates among patients. Malignant melanoma histopathological type had a worse prognosis than the other tumors.
