Combination chemotherapy with docetaxel and cisplatin for locally advanced and metastatic gastric cancer.

BACKGROUND

Poor treatment results obtained with palliative chemotherapy for advanced gastric cancer indicate the need for new effective and well-tolerated regimens.

PATIENTS AND METHODS

Forty-three patients with locally advanced or metastatic gastric cancer were enrolled in a phase II study to evaluate the efficacy and safety of combination chemotherapy with doxetacel 75 mg/m2 and cisplatin 75 mg/m2 given every three weeks.

RESULTS

Thirty-nine patients were evaluable for response. Four achieved a complete response and twelve a partial response, for an overall response rate of 37.2% (16 of 43 patients; 95% confidence interval (CI): 22.98-53.72). Median time to progression was 6.1 months and median overall survival 10.4 months. Forty-two percent of all patients were still alive at one year and twelve percent at two years. The major toxicity was leukopenia which reached grade 3-4 in 18.6% (n = 8) of the patients. However, no febrile neutropenia occurred. Non-haematological toxicities were usually mild to moderate. Grade 3 toxicities included diarrhea (9% of the patients), nausea and vomiting (7%), and alopecia (7%). Severe ototoxicity with or without peripheral neuropathy developed after completion of chemotherapy in two patients.

CONCLUSIONS

These results suggest that the combination of docetaxel and cisplatin has moderate toxicity and is an effective regimen for the treatment of advanced gastric cancer, both with regard to response rate and survival.
