Brachytherapy

This phase I/II trial tests the safety and effectiveness of receiving external beam radiation therapy (EBRT) and brachytherapy along with chemotherapy, consisting of cisplatin and paclitaxel, and immunotherapy, consisting of bevacizumab and pembrolizumab, for the treatment of patients with stage IVB cervical cancer. EBRT is type of radiation therapy that uses a machine to aim high-energy rays at the cancer from outside of the body. Brachytherapy, also known as internal radiation therapy, uses radioactive material placed directly into or near a tumor to kill tumor cells. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of tumor cells. Paclitaxel is in a class of medications called antimicrotubule agents. It stops tumor cells from growing and dividing and may kill them. Bevacizumab is in a class of medications called antiangiogenic agents. It works by stopping the formation of blood vessels that bring oxygen and nutrients to tumor. This may slow the growth and spread of tumor. A monoclonal antibody, such as pembrolizumab, is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Giving EBRT and brachytherapy along with chemotherapy and immunotherapy may be a safe and effective way to treat patients with stage IVB cervical cancer.

The purpose of the study is to explore the best ways of giving radiation therapy to balance cancer control and treatment side effects.

This phase III trial compares the addition of induction chemotherapy, with carboplatin, paclitaxel and pembrolizumab, to chemotherapy and radiation, with cisplatin and pembrolizumab followed by pembrolizumab maintenance for the treatment of patients with cervical cancer that has spread to nearby tissue or lymph nodes (locally advanced). Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of cancer cells. Paclitaxel is in a class of medications called antimicrotubule agents. It stops cancer cells from growing and dividing and may kill them. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of cancer cells. Adding induction chemotherapy to the usual treatment of chemotherapy and radiation followed by maintenance may be more effective in treating patients with high risk, locally advanced cervical cancer.
