Brachytherapy is a form of radiation therapy where a sealed radiation source is placed inside or next to the area requiring treatment. Brachy is Greek for short. 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. [1]
LDR brachytherapy is the one most commonly used to treat prostate cancer. It may be referred to as 'seed implantation' or it may be called 'pinhole surgery'. [1] In LDR brachytherapy, tiny radioactive particles the size of a grain of rice (Figure 1) are implanted directly into, or very close to, the tumour. These particles are known as 'seeds ...
The differences relate to the position of the radiation source; external is outside the body, brachytherapy uses sealed radioactive sources placed precisely in the area under treatment, and systemic radioisotopes are given by infusion or oral ingestion. Brachytherapy can use temporary or permanent placement of radioactive sources.
Management of prostate cancer. Treatment for prostate cancer may involve active surveillance, surgery, radiation therapy – including brachytherapy (prostate brachytherapy) and external-beam radiation therapy, proton therapy, high-intensity focused ultrasound (HIFU), cryosurgery, hormonal therapy, chemotherapy, or some combination.
Selective internal radiation therapy (SIRT), also known as transarterial radioembolization (TARE), radioembolization or intra-arterial micro brachytherapy is a form of radionuclide therapy used in interventional radiology to treat cancer. It is generally for selected patients with surgically unresectable cancers, especially hepatocellular ...
Radiation-induced lumbar plexopathy (RILP) or radiation-induced lumbosacral plexopathy (RILSP) is nerve damage in the pelvis and lower spine area caused by therapeutic radiation treatments. RILP is a rare side effect of external beam radiation therapy [1][2][3] and both interstitial and intracavity brachytherapy radiation implants. [4][5]
Iodine-125. Iodine-125 (125 I) is a radioisotope of iodine which has uses in biological assays, nuclear medicine imaging and in radiation therapy as brachytherapy to treat a number of conditions, including prostate cancer, uveal melanomas, and brain tumors. It is the second longest-lived radioisotope of iodine, after iodine-129. Its half-life ...
Prostate cancer is the uncontrolled growth of cells in the prostate, a gland in the male reproductive system below the bladder. Abnormal growth of prostate tissue is usually detected through screening tests, typically blood tests that check for prostate-specific antigen (PSA) levels. Those with high levels of PSA in their blood are at increased ...
