The purpose of this study was to evaluate the effect of immunotherapy combined with spatial fractionation radiotherapy and low dose radiotherapy on the prognosis of patients with advanced lung cancer under specific dose regimens (spatial fractionation radiotherapy: high dose region: 800-1200cGy × 3f, low dose region: 100-300cGy × 5f; low dose radiotherapy area: 100-300cGy × 5f). Through the phase II clinical trial, to determine the efficacy and safety of the combined treatment model in advanced lung cancer and its effect on the immune microenvironment of patients, so as to provide scientific basis for the optimization of treatment regimen for advanced lung cancer.

A phase II clinical trial of stereotactic radiosurgery versus radiofrequency ablation in the treatment of inoperable primary liver cancer in specific sites

The goal of this clinical trial is to learn the evidence-based medical value of 3D visualization techniques to improve tumor control, preservation of renal function, and perioperative safety in robot-assisted nephron sparing surgery for complex renal tumors. The main question it aims to answer is:
Is 3D visualization techniques more effective in improving robot-assisted nephron sparing surgery for complex renal tumors in terms of tumor control, renal function preservation, and perioperative safety.
The researchers will randomize participants into a 3D trial group and a conventional group for comparison.
Participants will:
Complete Blood routine, liver and kidney function tests on the first and third day after operation.
Have Renography at 3 and 12 months after the operation. Cooperate with follow-up visits.
