Abstract

Aims: We aimed to investigate the pre-treatment prognostic significance of lymphocyte/C-Reactive protein ratio (LCR), one of the inflammatory factors, in patients with extensive-stage small cell lung cancer (SCLC).
Methods: Medical records of 514 patients who were diagnosed with extensive-stage SCLC between 2010 and 2020 were examined retrospectively. LCR was calculated using the blood test results prior to chemotherapy.
Results: The mean survival time for extensive-stage SCLC is 6 months (5.3-6.7). A statistically significant difference exists between limited and extensive stages in terms of median overall survival (OS) (p<0.001). The baseline LCR value of the patients was determined as 0.5 (0-311). LCR exerts a statistically significant effect on overall survival (0.025). Every 1 unit increase in LCR reduces death by 1.004 times.
Conclusion: Pre-treatment LCR value can be used as an independent prognostic parameter associated with mean survival in extensive SCLC.

Yaygın evre küçük hücreli akciğer kanserinde lenfosit/C-reaktif protein oranının prognostik önemi

Abstract

Amaç: Yaygın evre küçük hücreli akciğer kanseri (KHAK) hastalarında inflamatuar faktörlerden lenfosit/C-Reaktif protein oranının (LCR) tedavi öncesi prognostik önemini araştırmayı amaçladık.
Araçlar ve Yöntem: Retrospektif olarak 2010-2020 tarihleri arasında KHAK tanısı almış ve yaygın evrede olan 514 hastanın tıbbi kayıtları incelendi. Kemoterapi öncesi alınan kan tetkiklerinden LCR hesaplandı.
Bulgular: Yaygın evre KHAK’nin ortalama sağkalım süresi 6 aydır (5,3-6,7). Sınırlı ve yaygın hastalık arasında medyan genel sağkalım (OS) açısından istatistiksel anlamlı farklılık vardır (p<0.001). Hastaların başlangıç LCR değeri 0,5 (0-311) olarak saptandı. LCR’nin genel sağkalım üzerinde istatistiksel anlamlı etkisi vardır (0,025). LCR’deki 1 birimlik artış ölümü 1,004 kat azaltmaktadır
Sonuç: Tedavi öncesi LCR, yaygın evre KHAK’de ortalama sağkalımı gösteren bağımsız bir prognostik parametre olarak kullanılabilir.
