Obesity and cancer

Q: Obese patients tend to have poor outcomes from chemotherapy?

A) True
B) False

Answer: A

The objective of the above question is to highlight one of the predictors which lead to poor outcomes in obese oncology patients. Most obese patients receive underdosing of anticancer agents. This is either due to the use of ideal or adjusted body weight or capping of the anti-cancer agent's dose. This issue has become more prevalent as the incidence of obesity has increased exponentially in society. With poor response more obese oncology patients tend to get admitted to ICU.
