Radiation therapy is commonly used in prostate cancer treatment. It may be used instead of surgery or after surgery in early-stage prostate cancer (adjuvant radiotherapy). Radiation treatments also can be combined with hormonal therapy for intermediate risk disease, when surgery or radiation therapy alone is less likely to cure the cancer.
Since its introduction in the mid-1980s, prostate brachytherapy has become a well-established treatment option for patients with early, localised disease. In the US, over 50,000 eligible prostate cancer patients a year are treated using this method. [12] Brachytherapy is now in widespread use across the world.
It is distinct from acute radiation syndrome, in that it occurs at dose rates low enough to permit natural repair mechanisms to compete with the radiation damage during the exposure period. Dose rates high enough to cause the acute form (> ~0.1 Gy/h) are fatal long before onset of the chronic form.
Body sites in which brachytherapy can be used to treat cancer. Brachytherapy is commonly used to treat cancers of the cervix, prostate, breast, and skin. [1]Brachytherapy can also be used in the treatment of tumours of the brain, eye, head and neck region (lip, floor of mouth, tongue, nasopharynx and oropharynx), [10] respiratory tract (trachea and bronchi), digestive tract (oesophagus, gall ...
Prostate cancer is the most diagnosed cancer in men in over half of the world's countries, and the leading cause of cancer death in men in around a quarter of countries. [91] Prostate cancer is rare in those under 40 years old, [92] and most cases occur in those over 60 years, [2] with the average person diagnosed at 67. [93]
Radiation therapy treatments to the head and neck regions for soft tissue, palate or bone cancer can cause chronic sinus tract draining and fistulae from the bone. [5] Lymphedema Lymphedema, a condition of localized fluid retention and tissue swelling, can result from damage to the lymphatic system sustained during radiation therapy.
Treatments tend to be 40 minutes or longer, resulting in greater OR time, more anesthesia and greater blood loss when compared to electron IORT. There are about 10 to 20 active centers using HDR-IORT for locally advanced and recurrent disease, and approximately 2000 patients have received this treatment, mostly for colorectal cancer, head and ...
Intraoperative electron radiation therapy is the application of electron radiation directly to the residual tumor or tumor bed during cancer surgery. [1] [2] Electron beams are useful for intraoperative radiation treatment because, depending on the electron energy, the dose falls off rapidly behind the target site, therefore sparing underlying healthy tissue.
