Abstract:
Objective:To investigate the clinical manifestations, endoscopic characteristics, and prognostic factors of patients with colorectal extranodal NK/T cell lymphoma.Methods:The clinical data of 52 patients with colorectal extranodal NK/T cell lymphoma admitted to the First Affiliated Hospital of Zhengzhou University from January 2013 to January 2023 were retrospectively analyzed. Their clinical manifestations and endoscopic characteristics were summarized, and the prognostic factors were analyzed by Cox regression model.Results:Among the 52 patients with colorectal extranodal NK/T cell lymphoma, there were 35 males and 17 females, with a male-to-female ratio of 2.06∶1. Among the general symptoms, abdominal pain was the most common (39 cases), and B symptoms occurred in 47 patients, among which fever was the most common lymphoma B symptom (42 cases), and gastrointestinal perforation was the most common complication (18 cases). Forty-three patients underwent colonoscopy, and the main manifestations under endoscopy were the ulceration type (24 cases). The ulcers were irregular at the edges and often covered with moss at the bottom. The median survival time was 4.3 months. Multivariate Cox regression analysis showed that hemocytic syndrome ( HR=8.50,95% CI: 1.679-8.328, P=0.001), serum albumin ( HR=3.59,95% CI: 1.017-6.551, P=0.048), and with or without chemotherapy ( HR=0.31, 95% CI: 0.246-1.061, P=0.025) were independent factors influencing the overall survival of patients with colorectal extranodal NK/T cell lymphoma. Conclusions:Colorectal extranodal NK/T cell lymphoma is a rare disease with a very poor prognosis. When patients present with abdominal pain and lymphoma B symptoms, and when ulcers with irregular edges and moss covering the bottom are found under endoscopy, the disease should be considered, and endoscopic biopsy should be taken in time for pathological diagnosis. The prognosis of patients with hemophagocytic syndrome and hypoproteinemia is poor. This disease should be treated with chemotherapy and surgery, and on this basis, hemophagocytic syndrome and hypoproteinemia should be treated to improve the prognosis of patients.
