A Prospective and Randomized Control Study on Effects of Thymalfasin for Injection on Perioperative Immune Function and Long-term Prognosis of Patients with Colorectal Cancer

The objective of this study is to explore the effects of thymalfasin for injection on perioperative immune function and long-term prognosis of patients with colorectal cancer (CRC). In total, 400 patients who entered the groups from February 2019 to January 2021 and underwent radical resection of CRC in the Fourth Hospital of Hebei Medical University were the study subjects. They were separated into experimental group (0-199, XELOX chemotherapy and thymalfasin for injection) and control group (200-400, XELOX chemotherapy) by random number table, and the experimental group was randomly divided into conventional-dose group (n = 100, 1.6 mg of thymalfasin for injection, twice a week) and high-dose group (n = 100, 1.6 mg of thymalfasin for injection, thrice a week) according to a ratio of 1:1, to analyze the effects of different treatment schemes on perioperative immune function and long-term prognosis of CRC patients. Compared with control group, the conventional-dose group and high-dose group had notably lower incidences of perioperative infection (P < 0.05), with no significant difference in both groups (P > 0.05). The experimental group had significantly lower overall incidence of early and late postoperative complications, local recurrence rate and the incidence of distant metastasis, and higher perioperative immune function indexes and median disease free survival (DFS) (P < 0.05).         The conventional-dose and high-dose thymalfasin for injection effectively improves the perioperative immune function of CRC patients and reduces the incidence of postoperative complications, as an effective treatment for such patients, which can benefit patients.
