Stereotactic External-Beam radiation Therapy, sometimes called SBRT is now being used to treat Small Cell Lung Cancer, and Sarcomas that have metastasized to the lungs. The high doses used in thoracic SBRT can sometimes cause adverse effects ranging from mild rib fatigue and transient esophagitis , to fatal events such as pneumonitis or hemorrhage.
Substrate reduction therapy offers an approach to treatment of certain metabolic disorders, especially glycogen storage diseases and lysosomal storage disorders. In a storage disorder, a critical failure in a metabolic pathway prevents cellular breakdown and disposal of some large molecule. If residual breakdown through other pathways is ...
Side effects of radiation therapy might occur after a few weeks into treatment. Both types of radiation therapy may cause diarrhea and mild rectal bleeding due to radiation proctitis, as well as potential urinary incontinence and impotence. Symptoms tend to improve over time except for erections which typically worsen as time progresses.
Margin "recipes" are being developed that will create linear equations and algorithms that account for "normal" variations. These rules are created from a normal population, and are applied to the treatment plan off-line. Possible side effects include random errors from uniqueness of the target
Androgen deprivation therapy (ADT), also called androgen ablation therapy or androgen suppression therapy, is an antihormone therapy whose main use is in treating prostate cancer. Prostate cancer cells usually require androgen hormones , such as testosterone , to grow.
Stereotactic surgery is a minimally invasive form of surgical intervention that makes use of a three-dimensional coordinate system to locate small targets inside the body and to perform on them some action such as ablation, biopsy, lesion, injection, stimulation, implantation, radiosurgery (SRS), etc.
[2] [6] [4] Treatment may include restarting the medication and slowly decreasing the dose. [2] People may also be switched to the long-acting antidepressant fluoxetine which can then be gradually decreased. [6] Approximately 15–50% of people who suddenly stop an antidepressant develop antidepressant discontinuation syndrome.
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 ...
