Oxaliplatin, Fluorouracil and Leucovorin （FOLFOX） as First-line Chemotherapy for Metastatic or Recurrent Colorectal Cancer Patients

OBJECTIVE To investigate the efficiency and safety of the oxaliplatin, fluorouracil(5-FU)and leucovorin regimen(FOLFOX)in previously untreated patients with metastatic or recurrent colorectal cancer. METHODS Previously untreated patients with metastatic or recurrent colorectal cancer received 100 mg/m2 of oxaliplatin intravenously(IV)over 2 h on day 1,and IV 400 mg/m2 of leucovorin over 2 h followed by a bolus of 400 mg/m2 of 5-FU.Then 2,600~3,000 mg/m2 of 5-FU was administered by continuous infusion over 46 h. RESULTS An evaluated response rate was determined for 97 of 105 treated patients.The overal response rate was 35.1%,9 patients(9.3%) had a complete response and 25 patients(25.8%)a partial response.Thirty-two patients(33.0%)developed stable disease and 32.0%of the patients progressed.The median time to progression(TTP)was 7.7 months and the median overal survival 20.5 months.One and 2-year survival rates were 68%and 32%.Toxic effects based on the National Cancer Institute-Common Toxicity Criteria(NCI-CTC),reaching grade 3/4 were:neutropenia 12.3%, anemia 11.3%,vomiting 4.1%and diarrhea 7.2%.Grade 3 neuropathy was 5.1%.The overall survival rate of patients who had received a radical resection was superior to the patients who had not received a operation,or had received a pal iative resection(P=0.0658).The serum levels of CEA,ALP and LDH had no relationship with survival(P>0.05). CONCLUSION The FOLFOX regimen containing oxaliplatin,5-FU plus leucovorin was an efficacious regimen with good tolerability in previously untreated metastatic or recurrent colorectal cancer patients.     

HCPT联合L-OHP方案治疗进展期结直肠癌的近期临床疗效

Objective： Although 5-fluarouracil-based chemotherapy has become a standard regimen for treatment of advanced colorectal cancer, the efficacy, as second line therapy, is not high. It is necessary to find a new regimen as a substitute for these patients. The study was to evaluate the short-time effects and toxicity of combination of HCPT plus L-OHP regimen in treatment of advanced colorectal cancer. Methods： Forty-seven patients with pathological evidence of advanced colorectal cancer were enrolled and were treated with HCPT plus L-OHP regimen for 86 cycles. All patients were treated with L-OHP 130 mg/m^2 day 1 and HCPT 6 mg/m^2day 1-4, the chemotherapy was repeated every 3 weeks as a cycle. The Short-time efficats and side effects were evaluated after 2 cycles for each patient. Results： 38 cases can be evaluated to short-time effects and achieved the overall response rate （CR＋PR） was 36.8%. KPS improved in 20 cases （52.6%）. In the total 86 cycles, the leucopenia occurred in 59 cycles （68.6%）,18 cycles （30.5%） in grade Ⅲ and Ⅳ and the diarrhea occurred in 48 cycles （55.8%）, 18 cycles （37.5%） in grade Ⅲ and Ⅳ. Conclusion： A satisfied response rate was obtained in advanced colorectal cancer patients treated by HCPT plus L-OHP regimen, especially who were the failure of first-line chemotherapy with 5-FU. The limited-dose toxicity was leucopenia and diarrhea.
