Abstract
Aims and Background
The treatment of inoperable malignant pleural mesothelioma is a challenge for the oncologist. Available chemotherapy regimens achieve poor results, therefore new agents or combinations are needed. In a phase I study, the combination of oxaliplatin and raltitrexed was shown to be active against malignant pleural mesothelioma. We herein report the results of a pilot study about the treatment of this disease.
Methods
From April 1999 to June 2000, we enrolled 11 chemotherapy-naïve patients with inoperable malignant pleural mesothelioma suitable to receive the following combination chemotherapy: raltitrexed, 3 mg/m2 iv, and oxaliplatin, 130 mg/m2, as a 2-hr infusion every 3 weeks.
Results
Four partial responses, 1 regression of disease (objective response rate, 45%; 95% Cl, 15.6-74.4%), 4 stable diseases and 2 progressions of disease were observed. An improvement in disease-related symptoms was recorded in all responders and in 2 patients with stable disease. Toxicity was mild, with no toxic-related death and only 1 episode of grade 4 neurotoxicity.
Conclusions
We consider the combination promising and worthy of further studies.
