Evaluation of the Prognostic Value of Obesity, Vitamin D Concentrations, and Systemic Inflammatory Response Indexes (SIRI, SII, PIV) in Patients With Breast Cancer Scheduled for Neoadjuvant Treatment
Introduction: The purpose of this study was to determine the prognostic utility of vitamin D concentrations and BMI (body mass index) values and the systemic immune-inflammation index (SII), the systemic inflammation response index (SIRI) and the pan-immune-inflammation value (PIV) to predict the ac...

| Summary: | Introduction: The purpose of this study was to determine the prognostic utility of vitamin D concentrations and BMI (body mass index) values and the systemic immune-inflammation index (SII), the systemic inflammation response index (SIRI) and the pan-immune-inflammation value (PIV) to predict the achievement of a complete response to neoadjuvant treatment (NAT) in patients with breast cancer. The correlations between systemic inflammatory response indices and vitamin D concentrations and BMI values were also analysed. Material and Methods: The study included 96 patients with breast cancer, prior to the start of NAT, of which 51 patients were diagnosed with triple-negative breast cancer (TNBC) and 45 patients with human epidermal growth factor receptor type 2 (HER2)-positive type. Results: The SIRI and PIV indices were shown to be significantly higher in patients with TNBC ( P = .001; P = .001) than in patients with HER2. There were no statistical differences in SII, SIRI, PIV, BMI, and vitamin D, according to the response to NAT treatment (pCR vs non-pCR). In the HER2+ group without pCR after NAT, there was a positive correlation of the SII coefficient with BMI values ( R = .41; P = .045). Furthermore, in the entire HER2+ group (irrespective of the NAT response), SII values were negatively correlated with vitamin D levels ( R = −0.39; P = .008). Conclusions: In patients with breast cancer, high SIRI and PIV values may indicate the biological subtype of TNBC. In the HER2+ group, higher SII values were associated with low vitamin D concentrations and elevated BMI. |
