Abstract

Nowadays more and more people are facing the health issue “obesity”. Usually, people would consider obesity as a risk factor to health. However, scientists found that obesity improved the survival of patients with cancer, which is called “obesity paradox”. This is a mutrual component in cardio-metabolic literature, but less in oncology. To identify the association between BMI and the treatment effect of Small Molecule Inhibitors (SMI) in gastrointestinal cancer, lung cancer, and renal cell carcinoma. We conducted a single center, retrospective study at Winship Center. We found that overall survival of patients are worse for low-weight patients compared with patients with high BMI during later period of these diseases, gastrointestinal cancer, lung cancer, and renal cell carcinoma. Overall survival of patients had adverse events were significantly shorter than patients had no adverse events.
