Pemetrexed plus carboplatin or cisplatin as neoadjuvant treatment of operable malignant pleural mesothelioma (MPM)

AIM: The objective of this study was the retrospective evaluation of tolerability and activity of pemetrexed with carboplatin (AC) or cisplatin (AP) as neoadjuvant chemotherapy in a consecutive series of patients with malignant pleural mesothelioma (MPM).

PATIENTS AND METHODS: Patients with operable MPM received three cycles of AC or AP followed by surgery and radiotherapy.

RESULTS: Since 2005, 51 patients have been treated with AC (27) and AP (24). We observed higher incidence of grade 3 anaemia, cumulative grade 2-3 asthenia and worsening of performance status in the AP group. Response to AC and AP were; complete: 4% vs. 0%, partial: 18% vs. 17%, stable disease: 74% vs. 79%, progressive disease: 4%; the resection rate was 81% vs. 79%.

CONCLUSION: AC and AP are active and feasible neoadjuvant regimens. Progression-free survival, response, disease control and resection rate were similar in the two treatment groups. The lower tolerability to AP treatment could impair the clinical condition of patients undergoing surgery.
