Clinical Trial Summary

The purpose of this study is to investigate the efficacy of intravenous lidocaine on THBS2, MMPs and VEGF-C in serum in cervical cancer patients undergoing radical hysterectomy under general anesthesia.

Description:

The surgical stress response to tumour removal causes bloodstream release of a variety of pro-inflammatory cytokines and other molecules which may affect perioperative immune response and other conditions conducive to residual tumour cell survival that could later emerge as clinical recurrences or metastasis. Lidocaine has analgesic and anti-inflammatory effects, and may also have specific anticancer properties.

Blood serum expression of these molecules (metalloproteinases, vascular endothelial growth factor [VEGF], epidermal growth factor）, play a important role in the metastatic process and tumor progression. lidocaine could affect the course and growth of metastatic tumors by changing the cancer cells, the tumor microenvironment, or both.

We tested the hypothesis that women undergoing cervical cancer resection with these techniques (intravenous lidocaine) have reduced postoperative serum expression of metastasis biomarkers, and may change the outcomes of cancer patients.
