Abstract

Introduction: Serum albumin, albumin-globulin ratio (AGR), neutrophil/lymphocyte (N / L) levels in patients with gastric carcinoma were investigated on survival impact. Methods: This study was planned as a pilot study. Biochemical parameters of 46 patients were obtained from archive retrospectively. AGR levels were calculated by AGR =albumin/Total Protein- Albumin formula. They were sorted by descending, AGR was evaualted with lower and upper by using ROC. Albumin and N/L were divided similarly.Results: AGR cut-off value was 1.295 with ROC, in ROC: 0.543 (62.5% sensitivity, 50% specificity). The mean overall survival's (OS) detected 20 months in lower AGR group, 28 ± 21 months in upper AGR group. A longer OS was detected in upper AGR group by Kaplan-Meier (p = 0.706, 95% CI: 0.295-0.791). According to ROC of level albumin's cut-off value was 4.05 mg/dL in the ROC: 0.545, (50% sensitivity, 58.5% specificity). The OS was detected 22 ± 21 months, in lower albumin group, 30 ± 26 months in upper albumin group. A longer OS was detected in upper albumin group by Kaplan-Meier (p=0.524, 95% CI:0.195-0.660). According to ROC, cut-off value of N/L was 2.445 in ROC:0.495, (50% sensitivity, 60.5% specificity). The OS was detected 32 ± 29 months in upper N/L group, 23 ±19 months in lower N/L group. A longer OS was determined in upper N/L group by Kaplan-Meier (p=0.965, 95% CI:0.247-0.748). There were no statistical significant differences regarding prediction of survival, mortality for patient's AGR, N/L, albumin levels by logistic regression analysis.Discussion: AGR, N/L, albumin levels may be not alone sufficient for prediction of survival, and mortality parameters in gastric cancer. It can be obtained more accurate results by increasing the number of cases.

Özet

Amaç: Serum albumin, albumin-globulin oranı (AGR), nötrofil/lenfosit (N/L) değerlerinin mide kanseri hastalarında sağkalım üzerine etkileri araştırıldı.Gereç ve Yöntem: Ön çalışma niteliğindeki bu çalışmaya kemoterapi değerlendirmesindeki 46 hastanın biyokimyasal parametreleri retrospektif olarak arşiv kayıtlarından alındı. AGR=Albumin/Total Protein-Albumin formülüyle AGR değerleri hesaplandı. Büyükten küçüğe doğru sıralanıp, (Receiver Operating Characteristic) ROC analiziyle AGR düşük-yüksek olarak değerlendirildi. Albumin ve N/L oranları da benzer şekilde gruplandırıldı.Bulgular: AGR' nin ROC analiziyle tespit edilen cut-off değeri; 1.295 (% 62.5 duyarlılık, % 50 özgüllük) idi. Kaplan-Meier metoduyla yüksek AGR grubunda düşük AGR grubuna göre daha uzun ortalama genel sağkalım (OS) tespit edildi. Sırasıyla (27 ± 21 aya karşı 26 ± 26 ay), (p: 0.706, % 95 CI: 0.295-0.791). ROC analiziyle albumin için cut-off değeri; 4.05 mg/dl (% 50 duyarlılık, % 58.5 özgüllük) idi. Kaplan-Meier metoduyla düşük albumin seviyeli olan grupda yüksek albumin seviyeli olan grupa göre daha uzun OS tespit edildi. OS; (30 ± 26 aya karşı 22 ± 21 ay), (p: 0.524, % 95 CI:0.195-0.660) dı, sırasıyla. ROC analizine göre N/L' nin cut-off değeri: 2.445 (% 50 duyarlılık, % 60.5 özgüllük) idi. Kaplan-Meier metoduyla OS' si yüksek olan N/L grubunda düşük olan gruba göre daha uzun olarak tespit edildi (32 ± 29 aya karşı 23 ± 19 ay), (p:0.965, % 95 CI: 0.247-0.748) idi. Logistic regression analizi ile AGR, N/L, albumin düzeyleri ile mortalite ve OS arasında istatitiki anlamlı ilişki tespit edilmemiştir.Sonuç: AGR, N/L, albumin düzeyleri mide kanserli hastalardaki mortaliteyi, sağkalımı öngörmede tek başlarına yeterli parametreler olmayabilirler. Vaka sayılarının arttırılmasıyla daha net sonuçlar elde edilebilinir.
