Abstract

Krishna PrasadBackground Development of treatment-induced hyperglycemia/diabetes is a considerable problem in women undergoing chemotherapy for breast cancer. In this study, baseline levels of blood cell-associated inflammatory indices (BCAII) were analyzed to understand their role in the development of treatment-induced hyperglycemia and diabetogenesis. Materials and Methods This was a retrospective study, and information on women who were normoglycemic and nondiabetic and of women who were diabetic at the beginning of the treatment were collected from files. Demographic, pathology-related details, and complete blood profile were noted. Neutrophil-to-lymphocyte ratio (NLR), derived neutrophil-to-lymphocyte ratio (dNLR), platelet-to-lymphocyte ratio (PLR), and systemic inflammatory index (SII) which indicate BCAII were calculated. Demographic details were subjected to frequency and percentage, while blood parameters were subjected to one-way analysis of variance followed by post hoc Bonferroni's multiple comparison tests. A p -value of <0.05 was considered significant. Results The results indicated that a significant difference in levels of total count ( p < 0.035), neutrophil, lymphocyte, and platelets ( p < 0.001) were observed. Regarding BCAII, when compared with women who were normoglycemic at the end of treatment, NLR, dNLR, PLR, and SII were significantly high for people who were known diabetics at the beginning of treatment ( p < 0.001). The dNLR ( p = 0.0008), PLR ( p < 0.001), and SII ( p < 0.001) were significant for people who developed secondary hyperglycemia/diabetes, while only dNLR was significant for people who progressed from normal to prediabetes stage ( p = 0.049) Conclusion To the best of the authors' knowledge, this is the first study that indicates difference in baseline BCAII and development of treatment-induced hyperglycemia/diabetes indicating that underlying low levels of inflammation may contribute to diabetogenesis in women affected with breast cancer.
