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, 2/3rd 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,
WBC, 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.
