Sarcomatoid malignant pleural mesothelioma: a case of long-term recurrence-free survival following curative intent surgery alone

Abstract

BackgroundCurative intent surgery may be indicated for some patients with resectable early stage malignant pleural mesothelioma (MPM). However, sarcomatoid MPM is a highly aggressive subtype for which curative intent surgery is generally not recommended.Case presentationWe present the case of a 63-year-old man who presented with dyspnea and chest tightness. Computed tomography revealed pleural thickening and nodular lesions. A pleural biopsy confirmed lymphohistiocytoid MPM (cT1N0M0, stage IA), prompting surgical intervention. The patient underwent left extrapleural pneumonectomy (EPP), and the final diagnosis was sarcomatoid MPM (pT2N0M0, stage IB). Although post-operative chemotherapy was planned, the patient refused additional treatment, because of the introduction of home oxygen therapy, and has remained recurrence-free for 10 years after the surgery.ConclusionsThis case presents a noteworthy instance of achieving long-term recurrence-free survival solely through curative intent surgery for sarcomatoid MPM. It highlights the potential efficacy of surgical intervention in managing this aggressive subtype, offering a glimmer of hope for improved outcomes. Further research is warranted to better define the role of surgery in the treatment of sarcomatoid MPM.
