Abstract

In the present study, the diagnostic value of voided urine cytology (VUC) and the bladder tumor antigen stat (BTA® stat) test were compared in transitional cell carcinoma (TCC) of the bladder. One hundred-seventeen patient with histologically confirmed TCC, 94 with benign genitourinary disease (GUD) and 21 healthy volunteers (HV) were enrolled in this study. Sensitivity and specificity were determined for the BTA® stat test and VUC by tumor grade and stage. The overall sensitivity of the BTA® stat test and VUC was 80.3% (95%CI=72.9-87.7%) and 28.2% (95%CI=20.0-36.4%), respectively (p<0.005). For tumor grades I and II, the sensitivities of the BTA® stat test and VUC were 52%, 88% and 6%, 24%, respectively. For grade III these figures were 93% and 49%. All HV were negative. However, 36 false positive results were found in benign GUD group by the BTA® stat test, resulting in specificities of 100% (95%CI= 98.2-100%) for VUC and 72.3% (95%CI=63.5-79.6%) for the BTA® stat test. The sensitivity of the BTA® stat test is significantly better compared to VUC in all grades, and this test can even detect low-grade tumors. The low sensitivity of VUC is confirmed. VUC, on the other hand, has a higher specificity compared to the BTA® stat test. It is concluded that this test could be used in the diagnosis and especially follow up of bladder cancer patients with some limitations.

Özet

Bu çalışmada, mesanenin değişici hücreli kanserinde (DHK) idrar sitolojisi ve BTA® (Bladder tumor antigen) stat testinin tanısal değeri karşılaştırıldı. Çalışmaya histolojik olarak DHK tanısı konmuş 117 hasta, benin genitoüriner hastalığı (BGH) olan 94 hasta ve 21 sağlıklı gönüllü (SG) dahil edildi. BTA® stat ve idrar sitolojisi için tümör grade ve evresine göre duyarlılık ve özgüllük değerleri tespit edildi. DKH olan hastalarda BTA® stat testi ve idrar sitolojisi için genel duyarlılık, sırasıyla %80.3 (95%CI=72.9-87.7%) ve %28.2 (95%CI=20.0-36.4%), (p<0.005) idi. Grade I ve II tümörlerde, BTA® stat testi ve idrar sitolojisi için duyarlılık ise sırasıyla, %52, %88 ve %6, %24 idi. Grade III tümörlerde bu değerler %93 ve %49 idi. Hem BTA® stat hem de sitoloji SG'lerin hepsinde negatif bulunurken, BGH grubunda BTA® stat testi ile 36 yanlış pozitiflik saptandı. Özgüllük ise idrar sitolcjisi için %100 (95%CI= 98.2-100%) ve BTA® stat testi için %72.3 (95%CI=63.5-79.6%) olarak sonuçlandı. BTA® stat testi duyarlılığı, grade dikkate alınmadan tüm DHK için idrar sitolojisine oranla çok daha iyi idi ve bu test ile düşük dereceli tümörler de tespit edilebildi. İdrar sitolojisinin duyarlılığı BTA® stat testine göre yetersizdi. Ancak, idrar sitolojisi BTA® stat testi ile kıyaslandığında çok daha yüksek özgüllüğe sahipti. BTA® stat testin bazı sınırlamalarla birlikte mesane kanserinin tanısında ve takibinde kullanılabileceğini düşünüyoruz.
