| Abstract | Colon cancer has a high incidence and mortality. Chemotherapy has been shown to increase response rate and survival. Relative dose intensity (RDI) is an important factor to determine chemotherapy efficacy. This research was aimed to evaluate the median of relative dose intensity (median RDI) in colon cancer patients who received chemotherapy. Methods: A retrospective cohort study was conducted in colon cancer patients who received chemotherapy at Sunpasitthiprasong hospital during January 1st, 2017 โ" December 31st, 2017. Descriptive statistics were applied to report a median RDI. Overall survival rate (OS) among patients who received high relative dose intensity greater than or equal to 80% (high-RDI) versus low relative dose intensity less than 80% (low-RDI) were compared using log-rank test. Simple linear regression was performed to analyze a relationship between RDI and hematologic parameters. SPSS version 26.0 (IBM Corp., Armonk, NY, USA) was used for all statistical analysis and data management. Results: Ninety colon cancer patients were enrolled. Majority of patients were male (56.7%) with mean age at diagnosis of 61.12 ยฑ 12.42 years old. of which 73.4% of patients were at early stage of colon cancer. A median RDI of chemotherapy was 81.32%ยฑ 24.79. Of which 53.33 of patients were at high-RDI group. A significant improvement of 1-year OS was seen in patients who were treated with high-RDI (97.87% vs 78.94%, p<0.001). A relationship between high RDI and hematologic suppression were not detected. Conclusion: This study demonstrated that a median RDI was 81.32% among colon cancer patients being treat at Sunpasitthiprasong hospital. Chemotherapy with high-RDI improved overall survival rate without increasing of hematologic toxicities. |
