Abstract Objective: To explore the relationship between the expression of GST-π, Ki-67, BMI and the clinical biological characteristics of rectal cancer patients and its clinical significance. Methods: A retrospective collection of 308 patients with rectal cancer who underwent surgery in the Second Affiliated Hospital of Wenzhou Medical University from January 2010 to January 2013 was completed and followed up for 5 years. We analyzed the association of body mass index (BMI) and the expression of tumor markers (Ki-67, GST-π) with clinical features and pathological features of rectal cancer, as well as the correlation between BMI and Ki-67, GST-π expression and its clinical significance in rectal cancer. The relationship between the 5-year survival rate of Ki-67 high-positive patients and BMI was also analyzed. Results: The high positive expression of Ki-67 in rectal cancer is closely related to the depth of infiltration of rectal cancer, TNM staging and poor 5-year survival rate (P<0.05). Compared with the normal BMI group, the high positive expression of Ki-67 and the weight loss group had a lower 5-year survival rate for rectal cancer after surgery (P<0.05) .The positive expression of GST-π in rectal cancer tissue was significantly correlated with weight loss, lymph node metastasis, lower rectal cancer, and higher TNM staging(P<0.05). Conclusion: The combined analysis of the correlation between BMI and GST-π and Ki-67 expression level plays an important role in the clinical evalvation of the malignancy of colorectal cancer and its prognosis.
