简要总结
This pilot phase 0 trial studies accelerated hypofractionated radiation therapy immediately before surgery in treating patients with malignant pleural mesothelioma (cancer in the thin layer of tissue that covers the lungs and lines the interior wall of the chest cavity). Radiation therapy uses high-energy x-rays to kill tumor cells and shrink tumors. Hypofractionated radiation therapy is a type of radiation therapy in which the total prescribed dose of radiation is divided into fewer but larger doses as compared to conventional radiation therapy. Giving accelerated hypofractionated radiation therapy immediately before surgery may improve survival, and may also reduce side effects experienced by patients with pleural mesothelioma.
详细描述
PRIMARY OBJECTIVES:
I. To determine the feasibility and toxicity (both acute and chronic) of accelerated hypofractionated neoadjuvant helical intensity modulated radiation therapy prior to pleurectomy/decortication for malignant pleural mesothelioma.
SECONDARY OBJECTIVES:
I. To determine the pathologic complete response rate (pCR). II. To determine the tumor local control rate (LC). III. To determine the malignant pleural mesothelioma disease specific survival (DSS).
IV. To determine the overall survival (OS). V. To assess transforming growth factor beta (TGF-B), interleukin (IL)-1, and IL-6 levels as predictive biomarkers for treatment induced tissue injury.
