Brief summary

The purpose of this study is to evaluate the safety, efficacy, and side effects of the CryoSpray Ablation(TM) System (CSA(TM) System) to treat neoplastic lesions on the parietal pleural surface.

Detailed description

The proposed study is a pilot study consisting of an estimated 10 subjects with biopsy-proven metastatic cancer in the parietal pleural surface treated with CryoSpray at dye marked metastatic foci. Initial treatment dosimetry will be up to 3 cycles of 10-40 second sprays. If necessary, dosimetry changes may occur after 3 subjects are treated and observed. It is unknown if dosimetry will need to be increased to enhance effectiveness. The PI may increase dosimetry by 1 cycle after each subject is treated and observed as a conservative approach to efficacy determination. If disease exists bilaterally, only one side will be sprayed.

Interventions

DEVICECryoSpray Ablation (TM) System

Subjects will be treated with spray cryotherapy using the CryoSpray Ablation (TM) System at Day 0 using up to 3 cycles of 10-40 second sprays as the studied dosimetry and will cover the affected area, including the tumor and the parietal pleural surface. If disease exists bilaterally, only one side will be sprayed. Subjects will be assessed 2-5 days from the initial treatment (Day 0) to check for mucosal sloughing, to reassess tumor burden and for additional CSA therapy as needed.
