Background and Aim: Due to the high prevalence of axillary nodules in mammograms, and the importance of hyloum and cortex dimensions in suspicion to be pathological as well as the role of obesity as a risk factor in breast cancer and prognosis of patients with breast canister, determining the relationship between body mass index (BMI) and the size of the lymph nodes in the exile can affect the approach to the importance of the size of the lymph nodes. The current study was carried out to investigate the correlation between obesity and the size of lymph nodes in angiography in screening mammograms.
Materials and Methods: In a descriptive study (from October 1996 to September 1997), we examined 204 patients who referred to Mahdieh Educational, Research, and Medical Center for mammography screening. The length and width of the observed axillary nodules were measured. The HCR criterion (hilo-cortical ratio) was calculated. Using independent sample t-test and Fisher's exact test, the association between lymph node and hyloma dimensions, Brest, and Sen density with BMI was investigated. Multivariable linear regression was used to assess the independent association of lymph node dimensions with BMI after adjusting age and brest density. Pearson correlation coefficient was also used to evaluate the inter-rater reliability between the two mammographic commentators.
Results: A strong and significant correlation was observed between BMI and length of lymph node R2 = 0.626), lymph node width R2 = 0.508), helium length (R2 = 0.558), helium width 64 /.= £ and HCR 35 /.= £ all of which are independent of breast age and density. No association was observed between BMI increase and Cortex lymph node thickness. Also, a strong correlation was observed between the increase in helium length and the increase in lymph node length ((R2 = 0.95). Similarly, a strong relationship was found between increase in helium width and lymph node width. Moreover, a significant correlation was found between HCR and BMI (R2 = 0/34).
Conclusion: It seems that the increase in the size of the lymph node is not related to the thickness of the cortex. Lymph nodes may be used in screening mammograms as an obesity biomarker and related pathologies; there is an excellent correlation between the dimensions of lymph node and obesity
