Summary of Key Findings on Metabolic Syndrome and Gynaecological Cancers

1. Link Between Metabolic Syndrome (MetS) and Cancer:

   • A systematic review published in the Indian Journal of Medical Research (IJMR) indicates that women with MetS face a significantly higher risk of developing various gynaecological cancers, including ovarian, endometrial, cervical, vaginal, and vulvar cancers.

2. Definitions and Prevalence of MetS:

   • Metabolic Syndrome is characterized by a cluster of metabolic disorders including obesity, hypertension, hyperglycemia, high triglycerides, and low levels of high-density lipoprotein (HDL) cholesterol.
   • The prevalence of MetS increases with age, affecting approximately 13% of young adults (18-29 years) to nearly 50% of individuals by age 50.
   • Prevalence among women is approximately 35%, compared to 26% in men.

3. Odds Ratios for Cancer Risks:

   • Endometrial Cancer: Odds Ratio (OR) of 1.99 (nearly double the risk for women with MetS).
   • Ovarian Cancer: OR of 3.44 (threefold increase in risk).
   • Cervical Cancer: OR of 1.9.
   • Vulvar Cancer: Hazard Ratio (HR) of 1.49 (49% higher risk).
   • Vaginal Cancer: HR of 1.54 (54% higher risk).

4. Research Context and Implications:

   • The review identified a significant gap in Indian studies relating to the comorbidity of MetS and gynaecological cancers, despite the growing burden of MetS and non-communicable diseases in India.
   • Authors emphasized the need for population-specific data to inform actionable health strategies.

5. Public Health Recommendations:

   • MetS management should be integral to strategies aimed at preventing and treating gynaecological cancers.
   • There is a strong call for integrating women with metabolic disorders, including diabetes, into preventive health programs for primary prevention and early detection of cancer.

6. Research Gap:

   • The authors recommend large-scale, prospective cohort studies in India to better understand the implications of MetS on gynaecological cancers.

7. Significant Research Contributors:

   • The research was conducted by a collaboration of scientists from the ICMR–National Institute of Reproductive and Child Health (NIRRCH), M.S. Ramaiah University, and Amrita Institute of Medical Sciences.

This systematic review highlights the critical relationship between Metabolic Syndrome and increased cancer risk in women, urging immediate attention to public health policies and research initiatives targeting these health concerns.
