Answer

Pseudomesotheliomatous adenocarcinoma has a poor prognosis, with a mean survival of approximately 7 months. In the study of Koss et al, the one-year survival was 39%, and the 18-month survival was 13%. [4] The prognosis of pseudomesotheliomatous lung adenocarcinoma is similar to that of diffuse epithelioid malignant mesothelioma. [46] Extrapleural pneumonectomy or therapeutic regimens of chemotherapy and/or radiation therapy have been used but are generally ineffective for this advanced form of lung adenocarcinoma. [4, 46]
