Endometrioid Endometrium Kanserinde Lenfovasküler İnvazyon ve Lenf Nodu Metastazı İçin Sistemik İnflamatuvar ve Nutrisyonel İndekslerin Prognostik Değeri

Öz

Amaç: Bu çalışma, endometrioid tip endometrium kanserli hastalarda preoperatif dönemde değerlendirilen inflamatuvar parametreler olan nötrofil-lenfosit oranı (NLR), trombosit-lenfosit oranı (PLR), monosit-lenfosit oranı (MLR), sistemik immün-inflamasyon indeksi (SII) ve C-reaktif protein (CRP) ile nutrisyonel göstergeler olan prognostik nutrisyonel indeks (PNI) ve albüminin, lenfovasküler invazyon (LVSI) ve lenf nodu metastazı (LNM) ile ilişkisini değerlendirmeyi amaçlamıştır. Gereç ve Yöntemler: Kasım 2023 ile Mayıs 2025 tarihleri arasında cerrahi uygulanan toplam 186 endometrioid endometrium kanserli hasta retrospektif olarak analiz edildi. Preoperatif kan parametreleri kullanılarak NLR, PLR, MLR, SII ve PNI hesaplandı. Hastalar LVSI ve LNM varlığına göre gruplandırıldı ve karşılaştırıldı. Her bir parametrenin ayırt edici gücünü değerlendirmek için alıcı işletim karakteristik (ROC) analizi yapıldı. Bulgular: LVSI saptanan 39 hastada PNI anlamlı derecede düşük, NLR, PLR, MLR, SII ve CRP ise anlamlı derecede yüksekti (tümü p<0,05). ROC analizinde, LVSI’yi öngörmede en yüksek AUC değeri NLR için bulundu (0,778). LNM saptanan 24 hastada NLR ve SII anlamlı derecede yüksek, lenfosit sayısı ise anlamlı derecede düşüktü (tümü p<0,05). PNI’nin LNM ile anlamlı bir ilişkisi bulunmadı. Sonuç: Preoperatif inflamatuvar indeksler, özellikle NLR ve SII, LVSI ve LNM riskinin öngörülmesinde klinik açıdan değerli biyobelirteçlerdir. PNI, LVSI pozitif hastalarda anlamlı derecede düşük bulunmasına rağmen ROC analizi prediktif performansının sınırlı olduğunu ortaya koymuştur. Bu nedenle PNI’nin, tek başına kullanıldığında zayıf kalan öngörü gücünün, diğer inflamatuvar indekslerle birlikte değerlendirildiğinde preoperatif risk sınıflamasına daha anlamlı katkı sağlayabileceği düşünülmektedir.

Prognostic Value of Systemic Inflammatory and Nutritional Indices for Lymphovascular Space Invasion and Lymph Node Metastasis in Endometrioid Endometrial Cancer

Abstract

Objective: This study aimed to evaluate the relationship between preoperative inflammatory parameters including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), systemic immune-inflammation index (SII), and C-reactive protein (CRP), as well as nutritional markers such as prognostic nutritional index (PNI) and albumin, with lymphovascular space invasion (LVSI) and lymph node metastasis (LNM) in patients with endometrioid endometrial cancer. Materials and Methods: A total of 186 patients with endometrioid endometrial cancer who underwent surgery between November 2023 and May 2025 were retrospectively analyzed. Preoperative blood parameters were used to calculate NLR, PLR, MLR, SII, and PNI. Patients were stratified according to the presence of LVSI and LNM, and compared accordingly. Receiver operating characteristic (ROC) analysis was performed to assess the discriminatory ability of each parameter. Results: In 39 patients with LVSI, PNI was significantly lower, whereas NLR, PLR, MLR, SII, and CRP were significantly higher (all p<0.05). ROC analysis showed that NLR had the highest AUC for predicting LVSI (0.778), indicating moderate discrimination. Among 24 patients with LNM, NLR and SII were significantly higher, and lymphocyte count was significantly lower (all p<0.05). PNI showed no significant association with LNM. Conclusion: Preoperative inflammatory indices, particularly NLR and SII, appear to be valuable biomarkers for predicting the risk of LVSI and LNM. Although PNI was significantly lower in patients with LVSI, ROC analysis demonstrated limited predictive performance. Therefore, the prognostic utility of PNI may be more meaningful when assessed in conjunction with other inflammatory indices, contributing more effectively to preoperative risk stratification.
