ABSTRACT
Objective:To compare the adjuvant chemotherapy project and survival prognosis of patients with stage Ⅱ/Ⅲ colon cancer in different age groups.Methods:In this retrospective study, the clinical data of 770 colon cancer patients undergoing radical resection were collected in the First Affiliated Hospital of Soochow University from Jan 2013 to Dec 2017. Patients were categorized into 3 groups based on age at onset of colon cancer: young group (18-49 years old, 112 cases), middle-aged group (50-64 years old, 351 cases) and older group (65-75 years old, 307 cases).Results:The young group had fewer complications, and the probability of cancer deposit, vascular tumor thrombus and nerve invasion was lower than the middle-aged and older group (12.5% vs. 15.4% vs. 14.3%; 7.1% vs. 9.4% vs. 8.5%; 2.7% vs .8.8% vs. 5.5%), but the probability of signet-ring cell carcinoma and mucinous adenocarcinoma was higher (5.4% vs. 1.4% vs. 1.6%; 14.3% vs. 11.4% vs. 13.4%), the proportion of patients with stage Ⅲ was greater (49.1% vs. 45.0% vs. 47.2%), and they were more willing to receive postoperative chemotherapy (83.9% vs. 81.8% vs. 60.3%). Among patients with stage Ⅱ and Ⅲ colon cancer, the young group and the middle-aged group were 3-4 times more likely to receive adjuvant chemotherapy than the elderly group [ OR=4.153 (95% CI:1.964-8.785), 2.906 (95% CI:1.845-4.579), 3.120 (95% CI:1.310-7.429), 3.588 (95% CI: 1.964-6.556)]. Of those patients who received chemotherapy, young and middle-aged patients had a higher percentage of multiagent regimen use than older patients [ OR=2.050 (95% CI:0.937-4.488), 2.750 (95% CI:1.536-4.923)]. Among patients treated with surgery alone, no significant differences were observed in survival among age groups. Among patients who received surgery and adjuvant chemotherapy, a significantly better survival was observed for young and middle-aged patients with stage Ⅲ [ HR=0.284 (95% CI:0.127-0.632), 0.521 (95% CI:0.333-0.816)] than their older counterparts. Conclusions:Among patients with stage Ⅱ/Ⅲ colon cancer, young and middle-aged patients are more likely to undergo adjuvant chemotherapy and use more radical chemotherapy regimen. Young and middle-aged patients with stage Ⅱ colon cancer had overuse of chemotherapy, but did not result in expected survival improvement.
