Abstract

Introduction: Nuclear Matrix Protein is a tumor marker using for early diagnosis and follow up of bladder cancer. This study was designed to determine the effectiveness of NMP 22 and cytology for early detection and follow up of bladder cancer. Material and Methods: Sixty-eight patients who were included hi this study were divided in three groups. The first group comprised 46 patients with hematuria and lower urinary tract symptoms, who had no previous history of bladder cancer. Seventeen patients were included in the second group who treated by transurethral resection of bladder tumor, partial cystectomy or intracaviter chemotherapy. The third group consisted of 5 patients with bladder tumor previously. They refused any kind of treatment. A reference value of 15 U/ml was utilized for NMP 22 in urine. A positive outcome was a tumor seen in cystoscopic examination, which was later histopathologically confirmed as malignant A negative outcome was tumor free cystoscopy, or benign histopathology of the suspected biopsy specimens. Urine cytology results were considered "malign" (severe dysplasia, malign and transitional cell carcinoma) and "benign" (metaplasia, inflamatory cells, dysplasia ). Results: Eighteen patients of the first group had bladder cancer, whereas NMP 22 was (+) in 29 patients in this group. However, NMP was (+) in 14 of the 18 patients with bladder tumor. The sensitivity and specificity of NMP 22 in group 1 were 77.7% and 46.6%, and that of cytology were 83.3% and 89.2% respectively. When all of the patients were evaluated together, the sensitivity and specificity of NMP 22 were 80.7% and 64.2%, and that of cytology were 88.4% and 90.4% respectively. Conclusion: In conclusion, this study indicates that NMP 22 reduces the necessity of cystoscopy, and it can be used as a screening test in combination with cytology.

Özet

Mesane tümörünün erken tanı ve izleminde kullanılan tümör belirleyicilerinden birisi nükleer matriks proteinidir. Bu çalışmada NMP 22'nin mesane tümörünün erken tanı ve izlemdeki yeri sitolojiyle karşılaştırmalı olarak araştırıldı. Çalışmaya alınan 68 hasta üç gruba ayrıldı. Tümör öyküsü olmayan, hematüri ve alt üriner sistem yakınmaları olan 46 hasta I. grupta, transüretral rezeksiyon, parsiyel sistektomi veya intrakaviter kemoterapi uygulanmış 17 hasta II. grupta, önceden tümör tanısı konulan fakat tedaviyi kabullenmeyen 5 hasta da III. grupta yer aldı. İdrarda bakılan NMP 22 için 15 U/ml, taban değeri olarak belirlendi. Sistoskopide tümör görülmemesi veya şüpheli olgularda yapılan biyopside tümör saptanmaması tümör (-), tümör görülmesi ve tümörün biyopsi ile doğrulanması tümör (+) olarak kabul edildi. Sitoloji için, ağır displazi, malin ve değişici epitel hücreli kanser tanısı olanlar malin, buna karşılık metaplazi, displazi ve iltihabi hücre değişiklikleri benin olarak kabul edildi. Birinci gruptan 29 hastada NMP 22 (+) bulunmasına karşın, 18 hastada mesane tümörü saptandı. On sekiz hastanın 14'ünde NMP 22 (+) idi. Bu grupta NMP 22 duyarlılığı %77.7, özgüllüğü %46.4 bulundu. Onsekiz olgunun 15'inde sitoloji (+) idi. Sitoloji duyarlılığı ve özgüllüğü %83.3 ve %89.2 bulundu. Atmış sekiz hastanın tamamında NMP 22 duyarlılığı %80.7, özgüllüğü %64.2 olurken, sitoloji duyarlılığı % 88.4, özgüllüğü %90.4 olarak belirlendi. Sonuç olarak, NMP 22'nin mesane tümörü izleminde sistoskopiye olan gereksinimi azaltacağı, tarama testi olarak ise sitoloji ile birlikte kullanılabileceği kanaatine varıldı.
