Abstract

BACKGROUND:

Extrapleural pneumonectomy (EPP) has been used as a treatment option for selected patients with malignant pleural mesothelioma (MPM). The primary end-point of this study was disease-free survival (DFS). Prognostic indicators for local and overall DFS were statistically analyzed.

METHODS:

Between October 1994 to April 2008, 59 patients who had complete macroscopic cytoreduction after EPP formed the basis of this report. In recent years, selected patients received adjuvant radiotherapy and pemetrexed combined with cisplatin or carboplatin. The clinicopathologic data of all patients were prospectively collected in a computerized database. Statistical analysis was performed by using Kaplan-Meier method and compared using the log-rank test. Cox-regression model was used for multivariate analysis.

RESULTS:

The mean age at the time of EPP was 59 (S.D. = 8) years. Nineteen patients (32%) experienced perioperative complications. The median survival was 21 months (range 2 to 104). The local disease recurrence rate was 51%. The median local DFS was 22 months (0 to 73). The overall disease recurrence rate was 64%. The median overall DFS was 18 months (range 0 to 73). In multivariate analysis, epithelial subtype (p = 0.026) and adjuvant radiotherapy (p = 0.023) were independently associated with an improved local DFS. Adjuvant radiotherapy (p = 0.011) was also independently associated with an improved overall DFS.

CONCLUSIONS:

This study demonstrated that that local disease failure was still a considerable clinical problem following complete EPP. The data also showed that patients with epithelial histology and receiving adjuvant radiotherapy were associated with an improved disease control.
