## How is chemo body surface area calculated?

Cancer Chemother Rep 1970;54:225-35.

- Equation: BSA (m2) = 0.0235 x Height(cm)0.42246 x Weight(kg)0.51456
- Equation: BSA (m2) = 0.024265 x Height(cm)0.3964 x Weight(kg)0.5378
- Equation: BSA (m2) = SQR RT ( [Height(cm) x Weight(kg) ]/ 3600 )

## How do you calculate surface area of a patient?

Body Surface Area (BSA)

- Calculate weight in kilograms: 210 pounds ÷ 2.2 = 95.45 kg.
- Calculate height in centimeters: 6 feet, 3 inches = 75 inches x 2.54 cm/inch = 190.5 cm.
- Multiply height by weight and divide by 3600. (190.5 cm x 95.45 kg) ÷ 3600 = 5.
- Take the square root of 5 = 2.24 m2

**How do you calculate BSA oncology?**

* Recommended by American Society of Clinical Oncology guidelines. ¶ Original formula estimated BSA in cm2; to convert to m2, divide result by 10,000….

Boyd* | BSA (m2) = 0.0003207 x Ht (cm)0.3 x Wt (g)(0.7285 – ( 0.0188 x LOG(Wt (g)))) |
---|---|

Gehan and George* | BSA (m2) = Wt (kg)0.51456 x Ht (cm)0.42246 x 0.0235 |

**What is a good BSA score?**

Average body surface area for adult women: 1.6 m2. Average body surface area for children (9 years): 1.07 m2. Average body surface area for children (10 years): 1.14 m2. Average body surface area for children (12-13 years): 1.33 m2.

### What is a good body surface area?

The “normal” body surface area is generally taken to be 1.7 m2 but, in actual fact, the body surface area depends on more than just height and weight. Other influential factors include the age and gender of the individual.

### What is a normal body surface area?

Average body surface area for adult men: 1.9 m2. Average body surface area for adult women: 1.6 m2. Average body surface area for children (9 years): 1.07 m2.

**How are chemo doses calculated?**

Dosage calculations for the majority of cytotoxic chemotherapeutic cancer drugs are based on the body surface area (BSA) of the patient, where the dosage is reported in milligrams, grams, or units per square meter of BSA. It is calculated for any cancer drug where the dose is based on BSA.

**What is a good body surface area number?**

The “normal” body surface area is generally taken to be 1.7 m2 but, in actual fact, the body surface area depends on more than just height and weight. Other influential factors include the age and gender of the individual. For example: Average body surface area for adult men: 1.9 m2.

#### What is the average body surface area?

The overall mean BSA was 1.79 m2 (95% CI 1.78–1.80) with a mean BSA for men of 1.91 m2 (1.90–1.92) and 1.71 m2 (1.70–1.72) for women. Results were consistent across the three centres.

#### How to calculate the BSA of chemotherapy drugs?

BSA in M2= 0.007184 x (Height in cm)0.725 x (Weight in kilos)0.425 This BSA calculator works as a chemotherapy dose calculator also and will give you the total dose of chemotherapy drug with one single click of the mouse. It also gives appropriate warnings as well.

**How do I calculate the surface area for medication doses?**

Body Surface Area Calculator for medication doses 1 Step 1 . Enter Height & Weight then click “Calculate”. 2 Step 2 . Safety Check. Set Age and Gender , then re-Calculate. 3 Step 3. Optional Medication Dose Calculator.

**How to calculate body surface area (BSA)?**

Step 1. Enter Height & Weight then click “Calculate”. Step 3. Optional Medication Dose Calculator BSA is a measurement used in many medical tasks. 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.

## Is there a software available for calculating dosages for chemotherapy protocols?

This software is provided “AS IS” and is intended for use only by qualified British Columbia healthcare providers familiar with calculating dosages for chemotherapy protocols. Reasonable effort has been made to ensure the accuracy of drug doses; however you should confirm and follow the doses and schedules set out by the drug manufacturers.
