P3.09-009 - Fourteen Cases Study of 5 Year Survivors of Malignant Pleural Mesothelioma Following Extrapleural Pneumonectomy (ID 9917)

- Abstract
Background:
We performed extrapleural pneumonectomy (EPP) as curative intent surgery for malignant pleural mesothelioma (MPM) from 2004 to 2012. We investigated that factors associated with long term survival in our current cases.
Method:
We retrospectively reviewed some factors concerning the patients underwent EPP from April 2004 to march 2017 and past more than 5 years after operation. We analyzed age, sex, epidemiology, side, clinical stage, measurements of pleural thickness, the value of SUV max of PET-CT, pathological stage, length from EPP to recurrence and end results.
Result:
A total of 54 patients were enrolled to this study. Six patients who had exploratory thoracotomy and three patients who had not macroscopic complete resection were excluded. Overall, 14 patients (31%) survived at least 5 years (Group S), and 31 patients (68%) survived less than 5 years (Group N). All patients had EPP. In Group S, 10 males (71%) and 4 females (29%); age when they had operation ranged from 37 to 69 years with a median age of 57.5 years. All of them, histological subtypes were epithelial type. By the comparison between Group S and Group N, there were significant differences among the value of SUV max of PET-CT validation of pre and post neoadjvant chemotherapy(＜3.0 vs ≧3.0, p=0.03), length from EPP to radiotherapy (＜60 days vs ≧60 days, p=0.02), length from EPP to recurrence (＜1 year vs ≧1 year, p=0.0001).
Conclusion:
More than 30% patients survived at least 5 years in this study. One patient survived more than 10 years. Another patient survived more than 8 years without recurrence. This case suggest that cancer of the patient possibly cured radically. In the future, we need comparison the prognosis, complication, quality of life (QOL) between the patients who underwent EPP and the patients who underwent pleurectomy/decortications (P/D).
