    Inflammatory Biomarkers from Blood Counts as Prognostic Tools in Metastatic Esophageal Cancer
    (Int Scientific Information, Inc, 2025) Urun, Yonca Yilmaz; Beypinar, Ismail
    Background: Globally, esophageal cancer ranks as the sixth leading cause of cancer-related mortality. This retrospective study from a single center in Turkey aimed to evaluate hematological inflammatory biomarkers in complete blood count (CBC) data and outcomes in 113 patients with advanced esophageal carcinomas. Material/Methods: We conducted a retrospective analysis of 113 patients with metastatic esophageal cancer composed of squamous (92), adenocarcinoma (18), and small cell (3) histology. We investigated neutrophil-to-lymphocyte ratio tory response index (SIRI), and aggregate index of systemic inflammation (AISI) in terms of prognosis. Results: The initial treatment for 25.7% of patients consisted of a carboplatin-paclitaxel combination. In response to the initial round of chemotherapy, 52.2% of patients showed improvement (15% complete, 37.2% partial), while 18.6% experienced disease progression. Neutropenia was observed as the most prevalent severe (grades 3-4) adverse reaction, affecting 19.8% of patients. Higher NLR, PLR, SII, NLPR, SIRI, and AISI values were associated with worse survival (P=0.016, P=0.008, P=0.011, P=0.028, P=0.014, P=0.001, respectively), whereas higher LMR was correlated with better survival (P=0.001). The NMR analysis showed no significant association (P=0.46). Multivariate analysis identified independent prognostic factors except histology, PLR, and NLPR. Conclusions: Research indicates that inflammatory indicators obtained from complete blood count analyses possess prognostic significance for individuals with metastatic esophageal cancer. These biomarkers demonstrate diverse capacities in forecasting the course of the disease. These simple and inexpensive markers need further confirmation to guide individualized treatment planning.
