A phase I study of paclitaxel and 5-fluorouracil in advanced gastric cancer.
No full textThis is a phase I study to determine the maximum tolerated dose (MTD) and toxicity of a combination of paclitaxel and 5-Fluorouracil (5-FU) in advanced gastric cancer patients. The patients, refractory to the PELF regimen (5-FU, leucovorin, cisplatin, epidoxorubicin), received weekly 5-FU at the fixed dose of 500 mg/m2, and escalating doses of paclitaxel every 3 weeks with a starting dose of 150 mg/m2 given as in 3-h infusion. The dose was escalated by 25 mg/m2 every 3 patients. Fifteen patients entered the study. The upper paclitaxel dose (225 mg/m2) was given to 6 patients. Up to this dose, no severe toxicity (grade 3-4) was recorded. Apart from alopecia, grade 1-2 leukopenia occurred in 5 patients and grade 1-2 neurotoxicity in 2 patients. All patients were evaluable for response (at least 2 cycles): 2 patients achieved an objective response (200 and 225 mg/m2). In 6 patients, treatment resulted in notable relief from symptoms. Out-patient paclitaxel given over 3 h and 5-FU may be combined safely for the treatment of patients with advanced gastric cancer. The recommended doses for phase II study are paclitaxel 225 mg/m2 and 5-FU 500 mg/m2

c-erbB-2 and common prognostic factors in breast cancer patients.
No full textWe report data on c-erbB-2, hormone receptors, and Ki-67 proliferation associated antigen in ninety-seven unselected breast carcinoma specimens. Immunohistochemical results and clinical data (age, axillary nodal involvement, menopausal status, tumor size) were compared. Positivity for c-erbB-2 staining was detected in the 46\% of tumors. There was no correlation among c-erbB-2 status and age, menopausal status, tumor size, lymph nodes involvement or Ki-67 index. An inverse relationship of c-erbB-2 and estrogen and progesterone receptor status was detected, although not statistically significant. Increased levels of c-erbB-2 were observed in 40-50\% of all the subsets of patients grouped on the basis of established prognostic factors. These higher levels could lead to the identification of further subsets of patients at higher risk of relapse. However, at present, the role of c-erbB-2 for clinical management of patients with breast cancer remains unclear

The clinical impact of FEM regimen (5-fluorouracil, 4-epidoxorubicin and mitomycin-C) in advanced gastric cancer patients.
No full textThe activity of FEM regimen in metastatic gastric cancer patients was assessed in seventy-seven patients receiving, as palliative treatment, 5FU 600 mg/m2 i.v. on days 1, 8, 29, 36; epiADR 70 mg/m2 i.v. on days 1, 29; MIT-C 10 mg/m2 i.v. on days 1, 29. Cycles were repeated every 58 days. One patient achieved a complete response and 12 a partial response, resulting in an overall response rate of 16\% (95\% CI: 8\% to 24\%). Median remission duration was 6 months. Median survival time for all patients was 8 months. Side-effects were mild and principally in the form of leukopenia (three episodes grade III). Our results support the recent findings about the lack of effectiveness of this regimen. Although it is a safe and well tolerable chemotherapeutic combination, FEM regimen should not be recommended as routinary treatment for gastric cancer patients who are not eligible for clinical trials
