Abstract

Aim: To evaluate the effectiveness of intracavitary bacillus Calmette-Guerin therapy in non-muscleinvading bladder tumors applied in patients at risk of relapse. Materials and Methods: Between May 2009-June 2013, 52 patients who were diagnosed or incidentally detected to have superficial bladder transitional cell tumor were evaluated. Initially epithelial transurethral resection was performed to these patients, and the patients proven to have superficial bladder cell tumor histopathologically were included in the study. After the surgery, the patients were divided into two groups such as low risk group and high risk group in terms of progression and relapse. In 30 patients comprising low risk group, intravesical Bacillus Calmette-Guerin Pasteur 81 mg was administered 1 time per week for 6 weeks 3 weeks after the procedure. In 22 patients comprising high risk group, 1 time per month dose of 27 mg Bacillus Calmette-Guerin was administered 3 times in addition to the previous 6 months therapy. In patients with relapse, transurethral resection was repeated and tumor grade, stage, progression and recurrence times were recorded. Results: The mean age of patients diagnosed with bladder cancer was 64.9 years (range: 20-91 years). Of the patients 11 were female, while the number of cases diagnosed under the age of 40 was 4. The youngest patient was 20 years old male. One of the cases was 13 weeks pregnant woman. The patients were followed up for an average of 40 months, and a recurrence rate of 13% (7 of 52 patients) was observed. Two of the 7 patients with recurrence showed some improvement in histopathological tumor grade and stage. Conclusion: Intravesical Bacillus Calmette-Guerin immunotherapy and induction Bacillus CalmetteGuerin therapy is an effective option in preventing tumor recurrence and progression after transurethral resection of non-muscle invasive superficial bladder cancer.

Özet

Amaç: Bu çalışmada, kasa invaze olmayan mesane tümöründe uygulanan intrakaviter Bacillus CalmetteGuerin tedavisinin nüks riski taşıyan olgularda etkinliğinin değerlendirilmesi. Gereç ve Yöntem: Mayıs 2009-Haziran 2013 tarihleri arasında transizyonel epitel hücreli yüzeyel mesane tümörü tanısı ile ya da insidental olarak bu tanıyı alan 52 olgu değerlendirmeye alındı. Bu hastalara başlangıçta transüretral rezeksiyon uygulandı ve ardından patoloji sonucuna göre yüzeyel mesane tümör tanısı alan olgular çalışmaya alındı. Cerrahi sonrası olgular progresyon ve nüks açısından yüksek riskli ve düşük riskli olarak iki sınıfa ayrıldı. Düşük riskli olarak sınıflandırılan 30 hasta işlemden 3 hafta sonra, 6 hafta süreyle haftada 1 kez intravezikal 81 mg Pasteur Bacillus Calmette-Guerin verildi. Yüksek riskli olarak değerlendirilen 22 olguya ise 6 haftalık tedaviye ek olarak ayda 1 kez olmak üzere toplam 3 ay BCG tedavisi uygulandı. Takipte nüks saptanan olgulara transüretral rezeksiyon yapılıp tümörün önceki sonucuna göre grade, evre, progresyon değişiklikleri ve nüks süreleri kaydedildi. Bulgular: Mesane tümörü tanısı alan olguların yaş ortalaması 64.9 (20-91 yıl) olarak belirlendi. Hastaların 11'i kadın, 41' i erkek 4'ü ise 40 yaş altındaydı. Özellik taşıyan hastalardan biri 20 yaşında, diğeri ise 13 haftalık gebe olan bir kadındı. Ortalama 40 ay süreyle takip edilen 52 hastadan 7' sinde (%13) nüks gözlenmiştir. Nüks gözlenen 7 hastanın 2'sinde (%2.8) histopatolojik olarak tümörün grade ve evresinde artış izlendi. Sonuç: Transüretral mesane tümörü rezeksiyonunu takiben orta ve yüksek nüks riski taşıyan, kas invaze olmayan mesane tümörlerinde, intravezikal Bacillus Calmette-Guerin immünoterapisi ve indüksiyon Bacillus Calmette-Guerin tedavisi, tümör nüks ve progresyonunu önlemede oldukça etkili bir seçenek olduğu gözlendi.
