Methods: Ten non-elderly patients (70 years) with advanced/recurrent colorectal cancer were enrolled in this prospective, multicenter cooperative group clinical trial. The mFOLFOX6 regimen was administered for eight cycles with maintenance therapy with oral UFT/LV treatment until progression. In cases with disease progression, mFOLFOX6 was reintroduced. Results: Grade 2 peripheral neuropathy was noted in 30.0% and 25.0% of the elderly and non-elderly patients, respectively. The observed time to treatment failure (TTF) was 6.3 months in the elderly patients and 6.4 months in the non-elderly patients. The disease control rate was 83.3% in each group. Conclusion: Our new stop-and-go strategy using oral UFT/LV is well-tolerated and effective even in elderly patients.展开更多

Methods: From March 2012 to March 2017 a total of 248 patients with advanced esophageal cancer were selected as the study subjects. According to random data table, they were divided into control group (n=123) and observation group (n=125) according to random data table. The control group was treated with cisplatin combined with fluorouracil, leucovorin chemotherapy, and patients in the observation group received oxaliplatin, leucovorin and fluorouracil chemotherapy, all patients were treated for 2 cycles. The changes of serum tumor markers, VEGF, CRP and matrix metalloproteinase levels in the two groups before and after treatment was compared. Results: Before treatment, there was no significant difference of the levels of serum CA125, CA19-9, CEA, VEGF, CRP, MMP-2 and MMP-9 between the control group and the observation group. Compared with the group before treatment, the levels of CA125, CA19-9, CEA, VEGF, CRP, MMP-2 and MMP-9 in the two groups were significantly lower. After treatment, the level of CA125, CA19-9, CEA, VEGF, CRP, MMP-2 and MMP-9 in the observation group was significantly lower than those of the control group. Conclusion:Oxaliplatin, leucovorin and fluorouracil chemotherapy can effectively reduce the levels of serum tumor markers, VEGF, CRP and matrix metalloproteinase in patients with advanced esophageal cancer, it has important clinical value.展开更多

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.展开更多

Methods: 23 patients of advanced colorectal cancer were treated with 5-FU 500 mg/d, civ, d1–d5, d8–d12, leucovorin 100 mg/d, iv gtt, d1, d8, folic acid tablet 60 mg/d, po, d2–d5, d9–d12, and oxaliplatin 65 mg/(m2?d), iv gtt, d1, d8, repeated every 21 days (one cycle).The effect was evaluated after two cycles. Results: Complete response in 2 cases and partial response in 10 cases were observed with an overall response rate of 47.18%. Adverse effects were mainly grade 1–2, including nausea, vomiting, diarrhea, dental ulcer, peripheral neuritis and myelosuppression. Conclusion: L-OHP/5-FU/LV regimen is an effective and better tolerated alterna- tive treatment in advanced colorectal cancer and yields promising clinical application.展开更多

UFT/LV showed antitumor effect against Meth A sarcoma,and the antitumor effect was enhanced when PSK given concomitantly. UFT/LV showed antitumor effect to Lewis lung carcinoma and PSK alone also showed antitumor effect at high dose,but a combination of UFT/LV and PSK resulted in no enhanced antitumor effect. Colon 26 carcinoma was weakly responsive to UFT/LV,and no enhancement of antitumor effect was found even PSK was used in combination. In conclusion,while the effect of PSK varies depending on tumor,combined use of UFT/LV and PSK may be expected to augment the antitumor effect.展开更多
