Dramatic advances have been made in brachytherapy for cervical cancer. This allows for better delineation and coverage of the tumor, as well as improved avoidance of surrounding organs. Consequently, advanced brachytherapy can achieve very high rates of local control with a reduction in morbidity, compared with historic approaches. This review provides an overview of state-of-the-art gynecologic brachytherapy, with a focus on recent advances and their implications for women with cervical cancer.
Intracavitary Brachytherapy for Gynecologic Malignancies: Applications and Innovations
Radiotherapy uses high energy x-rays to kill cancer cells. Internal radiotherapy means giving radiotherapy to the cancer from inside. A radioactive source is then placed inside the applicator or implant. The treatment gives a high dose of radiation to the cancer but very little to surrounding tissues.
Radiation therapy uses high-energy rays or particles to destroy cancer cells. It is sometimes used to treat cervical cancer. Your healthcare team will consider your personal needs to plan the type and amount of radiation, and when and how it is given.
Brachytherapy is a form of radiotherapy where a sealed radiation source is placed inside or next to the area requiring treatment. Brachytherapy is commonly used as an effective treatment for cervical , prostate , breast , esophageal and skin cancer and can also be used to treat tumours in many other body sites. Brachytherapy contrasts with unsealed source radiotherapy , in which a therapeutic radionuclide radioisotope is injected into the body to chemically localize to the tissue requiring destruction. It also contrasts to EBRT, in which high-energy x-rays or occasionally gamma-rays from a radioisotope like cobalt are directed at the tumour from outside the body. Brachytherapy instead involves the precise placement of short-range radiation-sources radioisotopes, Iodine for instance directly at the site of the cancerous tumour.
