Abstract

Introduction: Most of bladder tumors are urothelial cell carcinomas. Sarcomatoid carcinoma is a rare tumor of the urinary bladder and accounts for approximately 0.3% of all bladder malignancies. In these tumors, histogenesis and biological behavior remain controversial. Herein, we report five cases of sarcomatoid carcinoma of the urinary bladder. Materials and Methods: Between January 1998 and January 2003 a total of 5 patients with sarcomatoid carcinoma of the bladder were evaluated retrospectively. Preoperatively all patients evaluated with physical examination, routine hematologic analysis, urinary ultrasonography and computerized tomography. Results: Radical cystectomy was performed in 159 invasive bladder cancer patients in our department and of these, 5 (0.031%) were sarcomatoid carcinoma of the bladder. The mean age and mean follow-up period were 67.8 (range: 59-79) years and 13.4 (range: 6-19) months, respectively. At the time of diagnosis the tumors were staged as T3b in 3 cases, T3a in one case and T2 in one case. Primary therapy consisted of radical cystectomy in all cases. Four of 5 the tumors were macroscopically polypoid. Remaining one patient had a solitary tumor. All patients died of progressive primary disease. Conclusion: Our study shows that sarcomatoid carcinoma of the urinary bladder is aggressive and the overall prognosis of this tumor is very poor. Early diagnosis and radical surgery are the only options available to increase life expectancy for these patients. But poor prognosis and short survival time of these patients should be kept in mind despite radical surgical approaches.

Özet

Mesane kanserlerinin büyük bir kısmı (%95-98) ürotelyal hücreli kanserdir. Sarkomatoid mesane tümörleri oldukça ender olup tüm mesane kanserlerinin yaklaşık %0.3’ünü oluşturmaktadırlar. Bu tümörlerdeki etiyoloji ve klinik davranışlar tam olarak bilinmemektedir. Bu çalışmada mesanenin sarkomatoid kanseri tanısı ile izlenen beş hasta ile ilgili sonuçlar sunulmaktadır. Ocak 1998 ve Ocak 2003 tarihleri arasında invaziv mesane kanseri nedeni ile radikal sistektomi ameliyatı yapılan 159 hasta içinde mesanenin sarkomatoid kanseri tanısı konulan 5 (%0.031) hasta retrospektif olarak incelendi. Hastalar ameliyat öncesi ayrıntılı öykü, fiziksel inceleme, rutin biyokimyasal ve hematolojik tetkikler, üriner ultrasonografi, abdominopelvik tomografi, akciğer grafileri ve sistoskopi ile değerlendirildiler. Hastaların ortalama yaşı ve ortalama takip süreleri sırası ile 67.8 (59-79) yıl ve 13.4 (6- 19) ay olarak saptandı. Hastaların tamamında ilk yakınma makroskobik hematüri olarak görüldü. Tanı sırasında 3 hastada evre T3b tümör saptanırken bir hastada evre T3a tümör ve bir hastada da evre T2 tümör vardı. Dört hastada tümör polipoid görünümde iken bir hastada soliter yapıdaydı. Bütün hastalar radikal sistektomi ameliyatı geçirdi. Hastaların tamamında tümörler yüksek dereceli idi. Ortalama 13. 4 aylık takip sonunda olguların tamamının hastalık seyrine ve metastazlara bağlı olarak kaybedildiği görüldü. Bu çalışma, mesanenin sarkomatoid kanserlerinin son derece agresif seyrettiğini göstermektedir. Tanı sırasında bu tümörler çoğu zaman ileri evrededirler. Radikal cerrahi tedaviye karşın bu tür tümörlerin erken nüks ve progresyon göstereceği takipler sırasında göz önünde bulundurularak yakından takip edilmelidirler.
