neoadjuvant toripalimab combined with chemotherapy in the treatment of malignant pleural mesothelioma

Conditions: Malignant Pleural Mesothelioma

Summary: this is a single-arm, open, ii phase study to evaluate the safety and efficacy of toripalimab, pemetrexed and carboplatin in the treatment of locally advanced malignant mpm in 15 newly diagnosed patients with locally advanced malignant mpm.
