Abstract

Aims: To identify the clinical characteristics, the laboratory characteristics, the result of adjuvant chemotherapy with capecitabine for stage II colon cancer. Patients and methods: Retrospective longitudinal follow-up descriptive study. Patients aged 18-75 years diagnosed with stage II colon cancer who underwent radical surgery from January 2017 to June 2019 at K hospital received adjuvant chemotherapy with capecitabine. Results: 69 patients were initially eligible for the study.The medium age was 62. Sex ratio: 1/1. The main presenting symptom was abdominal pain (74,5%), hemorrhagia (58%). Common locations of tumor were sigmoid colon (46,4%) and right colon (23,2%). Major histological grades were grade 2 and grade 1 (94,2%). Stage IIA, IIB, and IIC were 30,4%, 62,2% and 4,3%. 5-year overall survival (OS) and 5-year disease-free survival (DFS) were 91.2% and 89.1%, respectively. The high-risk and low-risk groups had different 5-year DFS (86,5% và 87,5%, p= 0,002). Conclusion: Patients with Stage II colon cancer generally have an excellent prognosis. Adjuvant therapy with Capecitabine has improved both OS and DFS in this stage. However, the benefits of adjuvant chemotherapy in Stage II disease remains unclear, “high-risk” factors for recurrence play an important role in adjuvant chemotherapy decision-making in Stage II colon cancer.
