A chemotherapy regimen is a regimen for chemotherapy, defining the drugs to be used, their dosage, the frequency and duration of treatments, and other considerations.In modern oncology, many regimens combine several chemotherapy drugs in combination chemotherapy.
Naturally occurring rhodium (45 Rh) is composed of only one stable isotope, 103 Rh. [4] The most stable radioisotopes are 101 Rh with a half-life of 3.3 years, 102 Rh with a half-life of 207 days, and 99 Rh with a half-life of 16.1 days. Thirty other radioisotopes have been characterized with atomic weights ranging from 88.949 u (89 Rh) to 121. ...
At 3% fission products by weight, one ton of used fuel will contain about 400 grams of rhodium. The longest lived radioisotope of rhodium is 102m Rh with a half-life of 2.9 years, while the ground state (102 Rh) has a half-life of 207 days. [1] Each kilogram of fission rhodium will contain 6.62 ng of 102 Rh and 3.68 ng of 102m Rh.
The commonly used radioisotopes have short half lives and so do not occur in nature in large amounts. They are produced by nuclear reactions. One of the most important processes is absorption of a neutron by an atomic nucleus, in which the mass number of the element concerned increases by 1 for each neutron absorbed. For example, 13 C + n → 14 C
Some α emitting isotopes such as 225 Ac and 213 Bi are only available in limited quantities from 229 Th decay, although cyclotron production is feasible. [9] [10] [11] Among alpha-emitting radiometals according to availability, chelation chemistry, and half-life, 212 Pb is also a promising candidate for targeted alpha-therapy.
Infusion of R,C,H and O components of R-CHOP. Red flask contains doxorubicin (H), the most toxic component. Prednisolone (P) is administered on the next four or five days intravenously or in tablets. [1] CHOP is the acronym for a chemotherapy regimen used in the treatment of non-Hodgkin lymphoma. CHOP consists of:
ICE in the context of chemotherapy is an acronym for one of the chemotherapy regimens, used in salvage treatment of relapsed or refractory non-Hodgkin's lymphoma and Hodgkin lymphoma. In case of CD20-positive B cell lymphoid malignancies the ICE regimen is often combined today with rituximab. This regimen is then called ICE-R or R-ICE or RICE.
A 2024 systematic review of the literature found that chemoradiation with 5-FU and mitomycin C, as used in the Nigro Protocol, improves outcomes like colostomy-free survival in anal cancer patients compared to alternatives like cisplatin. However, it can lead to more severe side effects, especially blood-related toxicity. [7]
