Retrospective survival analysis of 237 consecutive patients with multiple pulmonary metastases from advanced renal cell carcinoma exclusively resected by a 1318-nm laser.

Objectives: Despite the introduction of new target drugs to treat pulmonary metastatic renal cell carcinoma (mRCC), complete surgical resection still generates significantly longer survival. We analysed the survival outcome for patients with pulmonary mRCC after extended laser metastasectomy with up to 110 metastases and systematic lymphadenectomy to assess the utility and value of laser resection in the respective patient groups even with high number of metastases.

Methods: Between 1996 and 2012, 237 patients (150 men, 87 women) underwent curative intended pulmonary laser metastasectomy of mRCC.

Laser resection technique and results of multiple lung metastasectomies using a new 1,318 nm Nd:YAG laser system.

Background And Objectives: Advantages of a new 1,318 nm Nd:YAG laser based on multiple lung metastasectomies are shown.

Study Design/materials And Methods: Ninety-three percent of 328 patients with metastases (8/patient, range 1-124) had precision laser resections (lobectomy-rate reduced to 7%); this laser delivers 20 kW/cm(2) 1,318 nm power densities with 400 microm fibers, and a focussing handpiece. Absorption in water is tenfold higher.
