Radiotherapy in which one or more radioactive sources are placed within a body cavity to irradiate the walls of the body cavity or proximal tissue.
Treatment directed into a body cavity. The advantage to this method is that very high doses of radiation can be delivered directly to a tumor site while sparing surrounding tissue.
Radiotherapy in which applicators holding radioactive sources are placed temporarily into body cavities until the desired radiation dose is delivered.
Treatment directed into a body cavity. In intracavitary radiation, for example, radioactive substances are put directly into body cavities, such as the mouth, chest, vagina, or anus. The advantage to this method is that very high doses of radiation can be delivered directly to a tumor site while sparing surrounding tissue.
Managing a cancerous growth within a hollow organ by introducing a radioactive implant or anticancer medications into the interior of the organ.
Intracavitary radiotherapy falls under the category of brachytherapy, a technique involving the insertion of radioactive wires or particles near the tumor. This approach is primarily employed for treating uterine and cervical cancers. Radioactive materials, often in the form of artificial radioisotopes contained within small tubes, are positioned close to the tumor and remain in place for a duration that varies from hours to days. The specific length of time depends on the type of radioactive substance used and the nature of the tumor being treated.
Intracavitary chemotherapy is employed for addressing a malignant effusion, which is an accumulation of fluid containing cancer cells, occurring in the chest or abdomen. The treatment serves to decelerate the fluid’s re-accumulation after drainage. Furthermore, intracavitary chemotherapy is utilized in managing bladder cancers. The chemotherapy drugs are introduced into the cavity through a flexible catheter and can either remain in situ or be removed after a specified duration.
