To estimate the effect and toxicity of bimonthly low-dose leucovorin (LV) and fluorouracil (5-FU) bolus plus continuous infusion(LV5FU2) with docetaxel combination chemotheraphy in patients with inoperable or postoperative relapsed gastric cancer.
Total 27 patients are enrolled in this study. LV 20 mg/m2 (bolus), 5FU 400 mg/m2 (bolus), 5-FU 600 mg/m2 (24-hour continuous infusion) on day 1, 2, 15, and 16, docetaxel 60 mg/m2 (1-hour infusion) on day 15 every 4 weeks.
Total of 141 cycles were administered and response rate were 36.8% with 2 complete response (10.5%) and 5 partial response (26.3%) in 19 evaluable patients. The median response duration is 8.1 months (95% CI, 4.0~12.1). The median progression-free survival time is 6.7 months (95% CI, 5.0~8.5) and the median overall survival time is 11.9 months (95% CI, 4.8~19.1). The grade 3-4 toxcity of neutropenia (24.8%) and anemia (11.3%), neutropenic fever (2.8%) is observed. The grade 1 toxcity of injection site reaction is observed all patients and the grade 1-2 toxcity of alopecia is observed 60%.
LV5FU2 with docetaxel combination chemotheraphy is effective and tolerable in patients with inoperable or postoperative relapsed gastric cancer.

We conducted a phase II study of docetaxel and ifosfamide chemotherapy for patients with platinum-resistant or refractory non-small-cell lung cancer (NSCLC) to evaluate the response and toxicity profiles as a salvage treatment.
Between July 2000 and July 2004, 40 patients who had previously received platinum-based regimen as the first-line or second-line therapy were enrolled in this study. The treatment consisted of a docetaxel 75 mg/m2 intravenous infusion on day 1 and intravenous ifosfamide 3 g/m2 with Mesna® uroprotectione on day 1 through 3. This regimen was repeated every 3 weeks.
One hundred thirty cycles of treatment were given, with a median of 3 cycles (range: 2~6 cycles). All the patients were evaluable for the response rate and toxicity profile. The major toxicity was myelosuppression. Grade 3~4 neutropenia occurred in 30 patients (75%) during treatment. Febrile neutropenia occurred in 16 patients (40%). Five of 40 patients (12.5%) had a partial response (95% confidence interval, 3.3~21.7%). The median time to disease progression was 2.65 months (range: 2.02~3.20 months), and the median survival was 5.24 months (range: 2.99~7.49 months).
Salvage chemotherapy with docetaxel and ifosfamide showed a low efficacy and a high proportion of severe neutropenia in patients with platinum-resistant or refractory advanced NSCLC.
