Predictive importance of systemic inflammation response index in de novo brain metastatic small cell lung cancer patients

Abstract

Aims: The subtype of lung cancer, known as small cell lung cancer (SCLC), tends to have a highly fatal course, especially in advanced stages. In particular, the overall survival durations further decrease in cases of brain metastases in SCLC. There is increasing evidence for the role of systemic inflammation parameters in predicting cancer prognosis, and they appear likely to become potential target markers for clinical treatments in the future. We aimed to evaluate the systemic inflammation response index (SIRI), a novel inflammatory laboratory marker that could predict long-term survival and serve as a potential target marker for clinical treatment, in patients with de novo brain metastatic small cell lung carcinoma (DNBM SCLC)."
 Methods: Clinicopathological features of adult patients diagnosed with DNBM SCLC were recorded from the patient registry of the hospital. Patients without medical records were not included in the study. Investigations were carried out to assess the prognostic effect of the SIRI parameter in predicting the 12-month overall survival (OS12) in DNBM SCLC patients, by determining a cut-off value and conducting appropriate statistical analyses, considering p-values (
