Alternatively, it is based on their body surface area (BSA).

Body surface area calculator . That said, the attempt to administer an exact dose based on a persons BSA may be futile. By correcting for BSA, it was generally assumed that cancer patients would receive a dose of a particular cytotoxic drug associated with an acceptable degree of toxicities without reducing the agent's therapeutic effect.

Step 3. Twelve rules for dose calculation of chemotherapy are given and consideration should be given to using fixed dose guidelines independent of body surface area and based on drug elimination capability, both as a starting dose and for dose adjustment, which may have accuracy, safety and financial advantages. The oncology team involved with chemotherapy treatment planning and administration assumes an active role in preventing such events by obtaining and maintaining competency in dose calculations, having knowledge of dose-limiting toxicities, appropriate ordering of drug regimens, and participation in safety verification processes. Dose = BSA Based Dose * 0.007184 * Height(cm)^0.725 * Weight(kg)^0.425.
