Testis kanserinde lenf nodu metastazını göstermede preoperatif nötrofil lenfosit oranının etkinliği

Amaç: Testis kanseri 20-35 yaş arası genç erkeklerde en sık görülen solid tümördür ve uygun tedavi ile çok iyi klinik sonuçlara sahiptir. Nötrofil-lenfosit oranının (NLR), farklı solid tümörlerde prognoz ve nüks ile ilişkili olduğu gösterilmiştir. Testis kanserinde lenf nodu metastazını varlığını göstermede NLR ile ilişkisini araştırmayı amaçladık. Gereç ve Yöntem: Çalışmaya toplam 72 testis kanseri hastası alındı. Tüm veriler geriye dönük olarak toplandı. NLR, nötrofil sayısının lenfosit sayısına bölünmesiyle hesaplandı. Tüm hastaların toraks ve batın bilgisayarlı tomografi (BT) taramaları metastaz açısından değerlendirildi. Bulgular: Ortalama yaş 32.18±8.89 idi. Patolojik sınıflama hastaların %43'ünde seminom ve %57'sinde nonseminom şeklindeydi. 72 hastanın 32'sinde (%44,4) lenf nodu pozitif, 40'ında (%55,6) lenf nodu negatifti. Hastaların ortalama NLO değeri 2,63±1,79 idi. Ortalama NLO, lenf nodu negatif hastalığı olan hastalarda anlamlı olarak daha düşüktü (lenf nodu pozitif hastalık için 3.19±2.32 ve lenf nodu negatif hastalık için 2.25±1.06). ROC analizinde, lenf nodu durumunu değerlendirmek için NLR için cut-off değeri olarak 2.5 belirlendi. Sonuç: Çalışma verilerimiz, NLR'nin testiküler GHT'lerde lenf nodu metastazlarını belirlemede kullanılabilecek düşük maliyetli ve hazır bir indeks olduğunu göstermektedir.

Efficacy of preoperative neutrophil-to-lymphocyte ratio in determining lymph node metastases in testicular cancer

Purpose: Testicular cancer is the most common solid tumor in young men between the ages of 20-35 and has excellent clinical outcomes with appropriate treatment. Neutrophil-to-lymphocyte-ratio (NLR) is related with prognosis and relapse in different solid tumors. We aimed to investigate the relation of presence and size of regional lymph node metastasis with NLR in testicular cancer. Materials and Methods: A total of 72 testicular cancer patients were included in the study. All medical records were retrospectively collected. NLR was calculated as the count of neutrophil divided by the count of lymphocyte. Chest and abdomen computed tomograpy (CT) scans of all patients were evaluated for metastases. Results: The mean age was 32.18±8.89 years. The pathologic classification was seminoma in 43% and nonseminoma in 57% of patients. Of 72 patients, 32 (44.4%) had lymph node positivity and 40 (55.6%) hadnot. The mean NLR value was 2.63±1.79 for all cohort. The mean NLR was significantly lower in patients with lymph node negative disease (for lymph node positive and negative disease 3.19±2.32 and 2.25±1.06, respectively.). In the ROC analysis, 2.5 was determined as the cut-off value for NLR to assess lymph node status. Conclusion NLR is a cheap and readily available index that can be used to determine lymph node metastases in testicular GCTs.
