Lidocaine was applied in the operation of colorectal tumor patients, and the effect on the postoperative microenvironment and micrometastasis of the patients was observed by detecting the stress, immunity, vascular tumor regeneration, inflammation, etc. of the patients.
Colorectal cancer (CRC) is one of the most common malignant tumors in the world. Surgical resection is the main treatment option for colorectal cancer patients. Surgery may enhance or accelerate tumor recurrence and metastasis. Multiple factors in the tumor microenvironment play important roles in tumor recurrence and metastasis, and modulating the tumor microenvironment can inhibit disease progression. Lidocaine has been found to inhibit tumor growth in animal experiments.
