The diminished reactivity limits protein-carboplatin complexes, which are excreted. The lower excretion rate of carboplatin means that more is retained in the body, and hence its effects are longer lasting (a retention half-life of 30 hours for carboplatin, compared to 1.5-3.6 hours in the case of cisplatin).
Because they have different dose-limiting adverse effects, they can be given together at full doses in chemotherapy regimens. [1] The first successful combination chemotherapy was MOPP, introduced in 1963 for lymphomas. The term "induction regimen" refers to a chemotherapy regimen used for the initial treatment of a disease.
Dosage of chemotherapy can be difficult: If the dose is too low, it will be ineffective against the tumor, whereas, at excessive doses, the toxicity (side-effects) will be intolerable to the person receiving it. [4] The standard method of determining chemotherapy dosage is based on calculated body surface area (BSA).
Second, the drug dose the patient received, and if its amount is commensurate with developing CIPN, must be considered. [1] The immunomodulatory drug bortezomib, for example, is more likely to cause neurotoxicity in a cumulative dose of 20 grams. Finally, the characteristics and the duration of a patient's symptoms should be analyzed.
A dose–response curve is a coordinate graph relating the magnitude of a dose (stimulus) to the response of a biological system. A number of effects (or endpoints) can be studied. The applied dose is generally plotted on the X axis and the response is plotted on the Y axis. In some cases, it is the logarithm of the dose that is plotted on the ...
For a structure receiving a very homogeneous dose (100% of the volume receiving exactly 10 Gy, for example) the cumulative DVH will appear as a horizontal line at the top of the graph, at 100% volume as plotted vertically, with a vertical drop at 10 Gy on the horizontal axis. A cumulative DVH from a radiotherapy plan.
Diagram of a catalytic reaction, showing the energy level as a function of the reaction coordinate. For a catalyzed reaction, the activation energy is lower.. In chemistry, a reaction coordinate [1] is an abstract one-dimensional coordinate chosen to represent progress along a reaction pathway.
In the clinic, a maximum recommended cumulative dose is set for anthracyclines to prevent the development of congestive heart failure. [35] As an example, the incidence of congestive heart failure is 4.7%, 26% and 48% respectively when patients received doxorubicin at 400 mg/m 2 , 550 mg/m 2 and 700 mg/m 2 . [ 4 ]
