Targeted alpha-particle therapy (or TAT) is an in-development method of targeted radionuclide therapy of various cancers. It employs radioactive substances which undergo alpha decay to treat diseased tissue at close proximity. [1] It has the potential to provide highly targeted treatment, especially to microscopic tumour cells.
Molecular structure of 3,4-diaminopyridine, a commonly used drug treatment for LEMS. If LEMS is caused by an underlying cancer, treatment of the cancer usually leads to resolution of the symptoms. [4] Treatment usually consists of chemotherapy, with radiation therapy in those with limited disease. [3]
Patients and their diseases are profiled in order to identify the most effective treatment for their specific case. Targeted therapy or molecularly targeted therapy is one of the major modalities of medical treatment (pharmacotherapy) for cancer, [1] others being hormonal therapy and cytotoxic chemotherapy.
In medicine, proton therapy, or proton radiotherapy, is a type of particle therapy that uses a beam of protons to irradiate diseased tissue, most often to treat cancer.The chief advantage of proton therapy over other types of external beam radiotherapy is that the dose of protons is deposited over a narrow range of depth; hence in minimal entry, exit, or scattered radiation dose to healthy ...
Most side effects are predictable and expected. Side effects from radiation are usually limited to the area of the patient's body that is under treatment. Side effects are dose-dependent; for example, higher doses of head and neck radiation can be associated with cardiovascular complications, thyroid dysfunction, and pituitary axis dysfunction ...
[5] [6] Radium-223 dichloride is an alpha particle-emitting radiotherapy drug that mimics calcium and forms complexes with hydroxyapatite at areas of increased bone turnover. [7] The principal use of radium-223, as a radiopharmaceutical to treat metastatic cancers in bone , takes advantage of its chemical similarity to calcium , and the short ...
Treatment types can be classified into local therapy (surgery and radiotherapy) and systemic treatment (chemo-, endocrine, and targeted therapies). Local therapy is most efficacious in early stage breast cancer, while systemic therapy is generally justified in advanced and metastatic disease, or in diseases with specific phenotypes .
Various approaches to approve effectiveness and limit side effects are being investigated, including radiosensitising drugs, fractionation regimes and new radionuclides. [16] Alpha emitters, which have much shorter ranges in tissue (limiting the effect on nearby healthy tissue), such as bismuth-213 or actinium-225 labelled DOTATOC are of ...
