Novel inflammatory markers and prognostic importance of platinum-sensitive ovarian carcinoma relapse

Abstract

Introduction/Objective. Ovarian carcinomas are the deadliest gynecological tumors. Despite advances in treatment options, survival rates are still not at the desired level. Since clinical signs are not typical in early-stage disease, two-thirds of patients are diagnosed late. Carbohydrate Antigen 125 (CA125) does not have sufficient sensitivity and specificity in early-stage disease and early post-relapse progression. There is a need for a simple and cost-effective marker that correlates with CA125. For this purpose, we aimed to evaluate the potential of systemic inflammatory markers? as diagnostic aids. Methods. Patients with platinum-sensitive recurrent ovarian carcinomas were preferred because the treatment options were more diverse than the resistant group. Using retrospective data collection, 105 patients with platinum-sensitive recurrent ovarian carcinoma, admitted in the last four years were included in the study. Complete blood count data was recorded based on recurrence and progression periods. Results. When the systemic immune inflammatory index (SII) values were evaluated in combination with CA125 in terms of progression during the control visits after platinum-sensitive disease recurrence treatment, progression detection proportions increased to 97.5%, which was 82.9% when only CA125 was used. On the other hand, false positivity, which was 18.5% for CA125 alone, decreased to 2.5% when combined with SII. Furthermore, neutrophil lymphocyte ratio, white blood cells, and neutrophil values showed correlations with high CA125 values. Conclusion. The SII value could be used together with CA125 because it is easy to use, accessible, and has low cost in clinical practice, as well as to increase the accuracy rate and make precise corrections in the false positivity rate.
