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 ...
The radiation does not affect the back passage (rectum, blue) at all. When LDR prostate brachytherapy (seed or polymer source implantation) is carried out, an ultrasound probe is inserted into the rectum (back passage), and images from this probe are used to assess the size and shape of the prostate gland. This is done so that the doctor can ...
[4] [9] Adverse effects may be class-dependent, and so switching to a biologic of another class may ameliorate those effects. [ 7 ] Potential serious adverse effects include allergic reactions , liver damage, cancer, and serious infections including tuberculosis , pneumonia , staph infection , and fungal infection .
Brachytherapy is commonly used as an effective treatment for cervical, [106] prostate, [107] breast, [108] and skin cancer [109] and can also be used to treat tumors in many other body sites. [110] In brachytherapy, radiation sources are precisely placed directly at the site of the cancerous tumor.
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.
Radiation therapy is used to kill cancer cells; however, normal cells are also damaged in the process. Currently, therapeutic doses of radiation can be targeted to tumors with great accuracy using linear accelerators in radiation oncology; however, when irradiating using external beam radiotherapy, the beam will always need to travel through healthy tissue, and the normal liver tissue is very ...
This may be done by placing a solid source of radiation adjacent to the tumor in the form of a seed, ribbon or capsule (brachytherapy) [1] or by giving the patient a liquid source of radiation that travels through the body and kills cancer cells (system therapy). In this case the radiation is usually given in the form of injections, ingesting a ...
These potentially harmful effects can be avoided by delivering the radiation more precisely to the targeted tissues leading to immediate sterilization of residual tumor cells. Another aspect is that wound fluid has a stimulating effect on tumor cells. IORT was found to inhibit the stimulating effects of wound fluid. [6]
