Spontaneous regression of malignant pleural mesothelioma: A case report

摘要

Abstract Malignant pleural mesothelioma (MPM) is a rare pleural disease with a poor prognosis. Currently treatment options are limited and the outcome is generally quite poor. We report the case of a 76-year-old man diagnosed with locally advanced {MPM} who had partial spontaneous response for 2 years and remained asymptomatic for more than 3 years. The patient was taking specific herbal and vegetable diet during the course of response. In our review of literature, a number of prognostic factors predict for better survival and response. However our patients did not have any of these factors. There have been reports of immune-induced responses in the literature. Our patient did indeed use some herbal products that might interfere with the immune system and explain his tumour regression and long period of disease stability. Further analyses and studies are needed in this setting to explore and identify specific immune pathways and targets to develop more effective treatment for MPM.
