Objective: The study aimed to explore the efficacy of pharmacokinetic-based 5-fluorouracil dose management by plasma concentration test in advanced colorectal cancer treatment.

Methods: 153 samples of advanced colorectal cancer patients were enrolled and randomly assigned to a control group and an experimental group. All patients received double-week chemotherapy with 5- fluorouracil (four weeks were used as one period), and chemotherapy duration ranged from 2 to 6 periods. In the first period, all patients were administered with the classic strategy of body surface area (BSA).

Results: In the subsequent periods, the control group (77 samples) continued with BSA guided chemotherapy, while the experimental group (76 samples) received pharmacokinetic AUC-based chemotherapy. The efficacy and toxic side effects were assessed during chemotherapy, and survival was recorded in a follow-up. In the AUC experimental group, the rate of diarrhea significantly decreased (37.50% vs. 70.00%, P=0.010), and incidence of oral mucositis reduced (54.17% vs. 82.50%, P=0.014). Compared with the control group, the clinical benefit rate of experimental group was much higher (90.79% vs. 79.22%, P=0.046).

Conclusion: There was no significant difference in other 5-fluorouracil related toxic side effect events (nausea, vomiting, hand-foot syndrome) and progression-free survival between the two groups. Pharmacokinetic- based dose management of 5-Fluorouracil reduces the toxicity of chemotherapy and improves long-term efficacy of chemotherapy for advanced colorectal cancer patients.
