Summary

Can neoadjuvant intrapleural cryotherapy be safely performed in patients with malignant pleural mesothelioma and will it trigger substantial systemic and local pro-inflammatory changes, resulting in the induction of anti-tumor immunity?

PROCEDURE

Cryotherapy

Subjects will have their blood drawn prior to undergoing a staging pleuroscopy. During the pleuroscopy pleural fluid will be collected as well as pleural biopsies (4 to 8 research biopsies). The procedure will involve 2 to 3 applications of cryospray on the location of the disease. After establishing cryofrost over a minimum of a 2 x 2 cm area, cryospray will continue for 15 to 20 seconds, allow a thaw period of 60 seconds followed by one to two repeats in the same location before proceeding onto the next location. We will treat a minimum of 6 x 6 cm area in aggregate. The freezing procedure will be video-recorded and freezing locations and time will be recorded. Approximately, 14 days following the staging pleuroscopy patients will undergo surgical treatment as per standard of care, with repeat blood, pleural fluid and tissue collection.
