Understanding Vaginoperitoneal Radiation Therapy for Gynecological Cancers

Vaginoperitoneal (VP) is a type of pelvic radiation therapy that uses a combination of radiation beams to treat cancer in the vagina and pelvis. It is typically used to treat gynecological cancers, such as cervical, endometrial, or vulvar cancer, as well as other types of cancer that have spread to the pelvis.

During VP radiation therapy, beams of radiation are directed at the tumor site from both the vagina and the peritoneum (the lining of the abdominal cavity). This allows the radiation oncologist to target the tumor more precisely and deliver a higher dose of radiation to the cancer cells while minimizing damage to surrounding healthy tissue.

VP radiation therapy is usually given in conjunction with other treatments, such as chemotherapy or surgery, and may be delivered through a variety of techniques, including external beam radiation therapy (EBRT) or brachytherapy (the placement of a radioactive source inside the body). The specific treatment plan will depend on the type and stage of cancer, as well as other individual factors.
