Brachytherapy is a form of treatment that is carried out by bringing radioactive sources (radiation source) into the immediate vicinity of the tumor. It is frequently used in the treatment of gynecological cancers (uterus, cervix, vagina), lung cancer, skin cancers.
Nowadays, brachytherapy, computed tomography and magnetic resonance imaging can be applied in 3D with imaging methods based on the section anatomy. The spread of 3-dimensional brachytherapy increases the success and decreases the side effects.
Brachytherapy is Applied in 3 ways
- Intracavitary brachytherapy (intracavitary brachytherapy): It is performed with the help of applicators placed inside the patient's natural cavities (uterus, cervix, bronchus, etc.).
- Interstitial brachytherapy (intraabdominal brachytherapy): It can be performed with the help of radioactive sources sent through the applicators or needles placed inside the tissues of the patient or as a permanent implantation of the radioactive sources (permanent prostate uLDR brachytherapy).
- Contact brachytherapy: It is the application of radioactive source / radiation source by removal of other organs during operation such as superficial tissues such as the skin or superficial intraoperative radiotherapy (IORT).
3D Brachytherapy in Gynecological TumorsIn the treatment of gynecologic cancers by physicians in different disciplines, the application of radioactive sources to the region to be irradiated has a very important role. The most common use of brachytherapy in the world is gynecologic cancers. Brachytherapy can be used as a single treatment method in patients with uterine cancers (endometryium), cervical cancers and vaginal cancers with external irradiation in postoperative or non-operative patients.
Especially in recent years, brachytherapy applications are developing from 2D methods to 3D methods. Based on the information from computed tomography and MRI, 3D brachytherapy applications can contribute to the successful treatment of gynecologic cancers, while maintaining the proper protection of the surrounding healthy tissues (such as the bladder, rectum, sigmoid). This means treatment with less side effects.
