    Author: Kato Y, Hasegawa Y, Wakita T, Hayashi N.
    Journal: Hinyokika Kiyo; 2005 Nov; 51(11):719-25. PubMed ID: 16363702.
    Abstract:
    A retrospective clinicopathological study was performed on 96 bladder cancer patients who underwent radical cystectomy and pelvic lymphadenectomy at Aichi Cancer Center between April 1994 and July 2004. The follow-up period ranged from 4 to 109 months, with a mean of 39.1 months. The overall cancer-specific survival rates at 3, 5 and 7 years were 81.7%, 71.2% and 71.2%, respectively. The 5-year survival rate according to pathological stage was 97.3% for pT1 or lower, 66.4% for pT2, 47.6% for pT3, and 25.4% for pT4. Univariate analysis demonstrated the prognostic significance of pathological stage (p < 0.001), lymph node metastasis (p = 0.001), venous invasion (p < 0.001), lymphatic invasion (p = 0.010), preoperative creatinine clearance (p = 0.001) and preoperative hydronephrosis (p < 0.001). Multivariate analysis revealed strong independent correlations of venous invasion (p = 0.040) and preoperative hydronephrosis (p = 0.016) with prognosis.
