When calculating the dose of chemotherapy in the presence of amputation, many physicians borrow the rule of nines from burn medicine as a way to estimate BSA. The calculator will determine the non-amputated weight based on the amputated weight and the extend of the amputations.

    In the adjuvant disease setting, 23 (12.7%) use ideal rather than actual body weight (BW) to calculate BSA, or choose whichever is less. Various Body Surface Area formulas have been developed over the years, originally by Dr.s Du Bois & Du Bois, followed by Gehan and George, Haycock, Boyd and Mosteller. Lately, we have had many opportunities for international collaborations, which make it necessary to review these BSA formulae, and the BSA-based dosing method. When you see the m, then you know you have to use the BSA to determine this dose. This Body Surface Area (BSA) Calculator helps you estimate the body surface area based on body weight and height. Body surface area is used to obtain the most accurate medication dosage on a patient based on the square meters of body surface area.

If you want to calculate the dose of a medication, you need to use the following equation: dose = weight * dosage. [] proposed using flat-fixed dosing regimens rather than body surface area (BSA)-based dosing for anticancer drugs because it does not seem worse than using BSA-based dosing with regard to pharmacokinetic variability.We feel that this statement, together with other recent publications arguing against BSA-based dosing, BSA became profitable within the last five years. That would generally be considered a positive, so we are surprised to see the share price is down. Other metrics may better explain the share price move.
