BACKGROUND: Chemotherapy based on platinum is the standard treatment for unresectable malignant pleural mesothelioma (MPM). Liposomal doxorubicin (LD) consists of pegylated phospholipid vesicles that encapsulate doxorubicin-enhancing liposome deposition in the tumour. We evaluated the toxicity profile and anti-tumour activity of cisplatin plus LD in untreated patients with MPM, as well as Tc-99m-LD distribution in MPM lesions after chemotherapy administration. METHODS: A total of 38 patients with non-resectable MPM received LD 40 mg m(-2) and cisplatin 60 mg m(-2) every 21 days. Gamma camera images of Tc-99m-LD were acquired to evaluate LD accumulation in measurable tumour tissue. The study was registered in Clinical Trials (NCT00886028). RESULTS: In all, 72% of patients were stage III and 28% were stage IV. Eighty four percent and 16% have high and low risk acording EORTC respectively. The median time to progression was 4.6 months (95% confidence interval (95% CI: 3.4-5.9 months), and median overall survival (OS) was 19.6 months (15.2-37.2 months). Patients that responded to chemotherapy treatment had better survival than patients who did not. Functional physical scales, dysnea, cough, and chest/arm pain demonstrated improvement. The accumulation ratio of LD in tumour and soft tissues vs liver was 0.78 +/- 0.16 and 0.29 +/- 0.09, respectively. After 1 h of administration, LD uptake in tumour tissue was higher than in soft tissue (P < 0.001). CONCLUSION: The combination of LD and cisplatin results in an active therapeutic regimen for unresectable MPM, with an acceptable toxicity profile and improvement in quality of life. Tc-99m-LD showed higher levels of tumour uptake as compared with surrounding tissues.
