Prognostic predictivity of the pretreatment platelet-to-lymphocyte ratio, mean platelet volume and platelet distribution width in laryngeal squamous cell carcinoma: Analyses of 594 patients

Abstract

Amaç: Tedavi öncesi trombosit-lenfosit oranı (PLR), ortalama trombosit hacmi (MPV) ve trombosit dağılım genişliğinin (PDW) larenks skuamöz hücreli kanserli (LSCC) hastaların prognozu üzerindeki etkisini değerlendirmektir. Gereç ve Yöntem: Çalışma popülasyonu iki gruba ayrıldı: sağ kalanlar (Grup 1) ve sağ kalmayanlar (Grup 2). Daha sonra, iki grup arasında yaş, cinsiyet, sigara içme durumu, lezyon lokalizasyonu, ön komissür tutulumu, tümör T evresi, N evresi, M evresi, erken/ileri evre ve tümör patolojik derecesi dahil olmak üzere çok sayıda değişken açısından kapsamlı bir karşılaştırma yapıldı. Genel sağkalımı (OS) tahmin etmek için ROC eğrisi analizi gerçekleştirildi. Daha sonra, kesme değerlerine göre gruplar oluşturuldu ve bu gruplar 3 ve 5 yıllık genel sağkalım (OS) oranları açısından karşılaştırıldı. Bulgular: Çalışmaya dahil edilme kriterlerini karşılayan 594 hasta alındı. Sağ kalan grup yaş ortalaması 59.8±9.18 yıl olan 419 (%70.5) hastadan (Grup 1) ve sağ kalmayan grup yaş ortalaması 62.4±11.17 yıl olan 175 (%29.5) hastadan (Grup 2) oluşuyordu. PDW (kesme değeri 16,35 fL) %78,3 duyarlılık ve %52,2 özgüllük ile kanser prognozunu öngörme potansiyeline sahipti. Ayrıca, PLR (kesme değeri 123.64) kanser prognozunu %70.2 duyarlılık ve %51.1 özgüllük ile öngörebildi. Sonuçlar: Tanı anında PDW >16.35 fL ve PLR >%123.64 olan LSCC hastalarının tedavi seçimi ve takibinde daha dikkatli olunmalıdır. Aim: The objective of this study was to assess the impact of pre-treatment platelet-to-lymphocyte ratio (PLR), mean platelet volume (MPV), and platelet distribution width (PDW) on the prognosis of patients with laryngeal squamous cell cancer (LSCC). Material and Method: The study population was divided into two groups: survivors (Group 1) and non-survivors (Group 2). Subsequently, we conducted a comprehensive comparison between the two groups with respect to a multitude of variables, including age, gender, smoking status, lesion localization, anterior commissure involvement, tumor T stage, N stage, M stage, early/advanced stage, and tumor pathological grade. ROC curve analysis was performed to estimate overall survival (OS). Then, groups were formed according to cut-off values and these groups were compared in terms of 3- and 5-year overall survival (OS) rates. Results: The study included 594 patients who met the inclusion criteria. The survivor group consisted of 419 (70.5%) patients with a mean age of 59.8±9.18 years (Group 1) and the non-survivor group consisted of 175 (29.5%) patients with a mean age of 62.4±11.17 years (Group 2). PDW (cut-off value 16.35 fL) had the potential to predict cancer prognosis with a sensitivity of 78.3% and specificity of 52.2%. Furthermore, PLR (cut-off 123.64) could predict cancer prognosis with a sensitivity of 70.2% and specificity of 51.1%. Conclusion: It was suggested that LSCC patients with PDW >16.35 fL and PLR >123.64% at the time of diagnosis should be more careful in treatment selection and follow-up.
