An early phase II study of etoposide (VP-16) in advanced gastric cancer

Infusional fluorouracil, etoposide, and cisplatin (FEP) in advanced and relapsed gastric cancer

We evaluated the efficacy and tolerability of a combination chemotherapy including infusional fluorouracil (5-FU), etoposide, and cisplatin (FEP) in 89 patients with advanced/relapsed gastric cancer. Primary endpoints were progression-free and overall survival. Secondary endpoints were response rates, response duration, and toxicity. The treatment schedule was as follows: 5-FU 1,000 mg/m2 and etoposide 100 mg/m2 were administered on 3 consecutive days and cisplatin at 80 mg/m2 was administered on day 2, and repeated every 3 weeks. The median times to progression and overall survival were 4 and 8 months, respectively. One-year progression-free and overall survival rates were 10% and 33%, respectively. The overall response rate for 25 eligible patients with measurable disease was 20% (5/25, complete response 2, partial response 3) with median response duration of 7 months. Median actual dose intensities of 5-FU, etoposide, and cisplatin were 700 mg/m2/wk, 70 mg/m2/wk, and 21 mg/m2/wk, respectively. Median relative dose intensities of 5-FU, etoposide, and cisplatin were 0.70, 0.70, and 0.63, respectively. In conclusion, the FEP regimen was found to produce therapeutic results similar to those of other combination chemotherapeutic studies and to have an acceptable toxicity. This regimen could be used as one of the options for advanced gastric cancer chemotherapy in patients unsuitable for doxorubicin-based regimens.

The chemotherapy of metastatic gastric adenocarcinomas with hypersecretion of alpha-fetoprotein or beta-human chorionic gonadotrophin: report of two cases

The chemotherapy of advanced gastric adenocarcinomas (GAs) is based on agents such as cisplatin, 5-fluorouracil and anthracyclins. Reproducible objective response rates are reported as approximately 40%. However, the median survival remains short, not exceeding 10 months. Amongst GA, a subset of tumours with increased plasma alpha-fetoprotein (alphaFP) and/or beta human chorionic gonadotrophin (betaHCG) levels form a well-defined histopathological entity. This subgroup has been associated with poor prognosis, due to the presence of poorly differentiated and rapidly proliferating cells. No specific chemotherapy has been proposed for this particular form of GA. We report two cases of patients with GA and hypersecretion of alphaFP and/or betaHCG. Despite bulky liver metastases and resistance to two standard chemotherapy regimens, both patients exhibited sensitivity to chemotherapy combining bleomycin, oxaliplatin and etoposide. These results suggest that patients with this particular subset of GA may benefit from chemotherapy regimens similar to those given to germ-cell tumour patients.
