Abstract:

Objective ·To explore the prognosis effects of tumor-stroma ratio(TSR), perineural invasion (PNI) and lymphovascular invasion (LVI) on patients with colorectal cancer (CRC). Methods ·Data of 948 patients diagnosed with CRC in Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine from January 2014 to December 2018 were retrospectively analyzed, and according to pathological risk factors TSR, PNI and LVI, patients were divided into high risk group (n=81) and low risk group (n=867). After 1∶1 matching with SPSS software, 67 patients of the high risk group and 67 patients of the low risk group were obtained. The overall survival (OS) time was compared between patients in the high risk group and low risk group. The results were validated by using tissue microarray (TMA) dataset of 106 CRC patients from our research group. The clinical characteristics of the high risk group and low risk group were compared. Kaplan-Meier curve was used for survival analysis, and COX regression model was used to analyze the prognosis factors. Results ·Patients in the high risk group had a worse prognosis with a short median OS (27.7 months) than patients in the low risk group (31.1 months, P=0.000). The worse OS in patients with high risk group was validated in matched data and TMA dataset. Conclusion ·CRC with positive perineural lymphovascular invasion combined with high TSR is a type of CRC with poor prognosis, which can effectively make up for the defect of tumor-node-metastasis (TNM) stage in prognosis and can be used to predict postoperative disease development of CRC patients and guide treatment.
