BACKGROUND: Pleural mesothelioma (PM) is a cancer with a usually dismal prognosis. However, long-term survivors do exist. Herein, we analyzed long-term survivors (>5 years after surgery) from high-volume centers around the world.
METHODS: This is a multicenter retrospective descriptive analysis of long-term survivors (overall survival ≥5 years from surgery) treated within a multimodality therapy approach, including macroscopic complete resection. Overall survival was calculated with Kaplan-Meier analysis, and patients were matched by center and surgery year and compared with a control group of short-term survivors (<2 years) in a conditional logistic regression analysis.
RESULTS: There were 276 long-term survivors (166 men [63%]), with a median age of 59 years (range 21-83 years) at the time of diagnosis. The histology was epithelioid for 246 patients and nonepithelioid for 30 patients. The disease was on the right side in 58% of the patients. As of this analysis, 148 patients had died, 104 were alive, and 10 were lost to follow-up. Pathologic tumor stages were: pT1 (n = 50), pT2 (n = 63), pT3 (n = 90), or pT4 (n = 16) and pN0 (n = 150), pN1 (n = 20), and pN2 (n = 39). The matched control data set included 333 patients, 95 cases and 238 controls. Comparing short- with long-term survivors, we found moderate evidence that a low white blood cell count before surgery was more often observed in long-term survivors.
CONCLUSIONS: The data show that long-term survival in PM is possible in a subgroup of surgically treated patients. Histologic subtype and white blood cell count seem to be prognosticators for longer survival.
