Computerized Tomography: An Unreliable Method for Accurate Staging of Bladder Tumors in Patients who are Candidates for Radical Cystectomy

Abstract: A total of 164 patients with bladder tumors underwent preoperative staging by computerized tomography. All patients were previously untreated, or had undergone only transurethral biopsy or resection of the tumor before computerized tomography. The post-cystectomy histological stage was compared to the preoperative computerized tomography stage. Computerized tomography accuracy according to the tumor, nodes and metastasis classification was only 32.3%, whereas overstaging was found in 39.6% and understaging in … Show more

“…However, the correlation between CT findings and tumor extent in cystectomy specimens is relatively limited, ranging from 65 to 80% [5,8] . Paik et al [5] reported that CT understaged extravesical tumor spread in 20.7% of the cases, and Voges et al [9] reported that CT was unable to detect 69% of tumors that actually extended beyond the bladder wall. In our study, sensitivity, specificity and accuracy of CT in the diagnosis of extravesical tumor extension was 85.4, 62.7 and 72%, respectively.…”

“…4 Thereby, the sensitivity of CT for assessment of perivesical extension has been reported to be within the range of 60% to 96%. 5,[9][10][11] Conversely, the sensitivity of MRI and transrectal ultrasonography for preoperative staging of bladder cancer was calculated to be 88% for each in a previous study by Ruether et al 12 In general, the reported accuracy rates for overall staging were of a moderate degree at most for both CT and MRI, being within the ranges of 55% to 92% 13 for the former and 62% to 96% 6,13 for the latter. Transurethral ultrasonography (TUUS) has also been reported to be a diagnostic option in bladder cancer staging despite having technical limitations such as acoustic shadows produced by tumor interface calcification and absorption of ultrasound by large tumors.…”

“…Algunos estudios afirman que la TAC ha demostrado su capacidad para determinar afectación perivesical, aunque bastantes de estos trabajos están escrito por radiólogos 2,9,10 , mientras que desde el punto de vista del urólogo el tema sugiere no pocas incógnitas 1,3,4,5,6,8 , habiendo autores que llegan a afirmar en las conclusiones de sus trabajos que la TAC, no aporta más datos que la resección transuretral del tumor 4 . Uno de los aspectos más controvertidos en cuanto a la utilidad de esta técnica en el estadiaje prequirúrgico del carcinoma vesical infiltrante es, hasta que punto haría cambiar la actitud operatoria de cara a decidirnos por una u otra cirugía, o incluso tomar la determinación de no operar, administrar quimioterapia, etc.…”
