A 6 microRNA Tool for Stratifying Stage II Colon Cancer of Receiving Adjuvant Chemotherapy

June 8, 2015 updated by: Wu Song, First Affiliated Hospital, Sun Yat-Sen University

A Multi-site, Open, Perspective Study of Prognostic Value and Benefit From Chemotherapy of Stage II Colon Cancer Based on a 6 microRNA Stratified Tool

Whether patients with stage II colon cancer should receive adjuvant chemotherapy or not is still on debate.MicroRNA(miRNA) is a promising tool. Investigators invented a tool consisting of 6 miRNA(miR-21、miR-20a-5p、miR-103a-3p、miR-106b-5p、miR-143-5p and miR-215) that was effective to identify one should accept adjuvant chemotherapy or not. Here investigators randomly assign patients to be assessed by classical pathological features or the miRNA tool of determining who should accept chemotherapy. Disease free survival and overall survival are the end points of observation.

Detailed Description

Investigators randomly assign patients to be assessed by classical pathological features(control group) or the miRNA tool(experimental group). Pathological features include poorly differentiated histology(exclusive of those cancers that are MSI-H),lymphatic/vascular invasion,bowel obstruction and <12 lymph nodes examined.MicroRNA tool contains miRNA of miR-21、miR-20a-5p、miR-103a-3p、miR-106b-5p、miR-143-5p and miR-215. Investigators evaluate these miRNA status of surgical specimens using qRT-PCR and calculate their risk score(risk score =(0.108×status of miR-21-5p)+(0.086×status of miR-20a-5p)+(0.240×status of miR-103a-3p)+(0.095×status of miR-106b-5p)-(0.238×status of miR-143-5p)-(0.237×status of miR-215),low expression status equals 0 and high expression status equals 1). Investigators defined high risk patient if had any pathological features in control group or the score larger than 1 in the experimental group ,the others as low risk patient.The high risk group should receive adjuvant chemotherapy while the low risk group deserve observation. Primary endpoint is the disease free survival and overall survival.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: An experimental group
A 6 microRNA stratified tool is applied in this group.Investigators defined high risk patient and low risk patient according to the microRNA stratified tool.The high risk group should receive adjuvant chemotherapy while the low risk group observation.
Other: A 6 microRNA stratified tool
Investigators randomly assign patients to be assessed by a 6 microRNA stratified tool. MicroRNA(miRNA) tool contains miRNA of miR-21、miR-20a-5p、miR-103a-3p、miR-106b-5p、miR-143-5p and miR-215. Investigators evaluate these miRNA status of surgical specimens using qRT-PCR and calculate their risk score(risk score =(0.108×status of miRNA-21-5p)+(0.086×status of miRNA-20a-5p)+(0.240×status of miRNA-103a-3p)+(0.095×status of miRNA-106b-5p)-(0.238×status of miRNA-143-5p)-(0.237×status of miRNA-215),low expression status equals 0 and high expression status equals 1). Investigators defined high risk patient if their score larger than 1, the others as low risk patient.The high risk group should receive adjuvant chemotherapy while the low risk group deserve observation.
Other: A control group
A classic stratified tool is applied in this group. Investigators defined high risk and low risk patient according to classical pathological features.The high risk group should receive adjuvant chemotherapy while the low risk group observation.
Other: A classic stratified tool
Investigators randomly assign patients to be assessed by by classical pathological features. Pathological features include poorly differentiated histology(exclusive of those cancers that are MSI-H),lymphatic/vascular invasion,bowel obstruction and <12 lymph nodes examined. Investigators defined high risk patient if they had any pathological features, the others as low risk patient. The high risk group should receive adjuvant chemotherapy while the low risk group deserve observation.
