Introduction: Gynecologic malignancies are estimated to affect 110,070 women and will be the cause of death in approximately 32,120 in 2018. Endometrial cancer is among the most prevalent with 63,320 estimated new cases and approximately 11,350 deaths, followed by ovarian cancer with an estimate of 22,000 new cases and 14,000 deaths annually. Obesity is one of the most modifiable risk factors. Providers should engage in a multifaceted approach to patient education and healthcare to decrease the projected cases of obesity-related cancers.
Background: The literature demonstrates a significant link between obesity and the development of certain malignancies such as endometrial, pancreatic, and renal cancer. Specific mechanisms found to play a role in the development of these malignancies include alterations of the metabolic pathway attributed to lipid accumulation as well as a chronic inflammatory process. Obesity also predisposes patients to other medical comorbidities as well as a poorer prognosis once a diagnosis of cancer is established. Factors contributing to poorer prognosis include challenges with treatment planning, specifically pertaining to inappropriate chemotherapy dosing and delivery of radiation therapy. Surgical approach and perioperative management are similarly challenging in obese patients and are associated with increased risk of complications.
Conclusion: Obesity is a modifiable factor which is associated with an increased risk of cancer and poorer outcomes. Providers should educate patients on all health hazards of obesity, including increased risk of cancer, and encourage them to participate in a structured weight loss plan.
