Efficacy and Safety of Multimode Thermal Therapy in the Treatment of Early Peripheral Lung Cancer

Обзор

The purpose of the study is to evaluate the efficacy and safety of multimode thermal therapy for early peripheral lung cancer, and to explore the changes of systemic immune microenvironment after multimode thermal therapy.

Подробное описание

This is a single-center, single-arm, exploratory study, and is expected to enroll a total of 10 patients. The enrolled patients were stage IA lung cancer patients with lung lesions found on chest CT, pathologically diagnosed as non-small cell lung cancer, negative for driver gene mutations, and who were considered high-risk or refused surgery by multidisciplinary evaluation. Follow-ups are performed after the multimode thermal therapy. The primary endpoint is complete ablation rate at 6 months after multimode thermal therapy. The secondary endpoints are complete ablation rate at 12 months after multimode thermal therapy, local control rate at 1, 2, 3 years post-procedure, progression-free survival and mmune effects after multimodal thermal therapy.

Вмешательства

• Устройство Multimode thermal therapy
  The multimode thermal therapy procedure consists of a sequential rapid freezing, natural thawing, and radio-frequency (RF) heating of the target tumor tissue.
