    Abstract:
    OBJECTIVE: The presence of lymph node metastasis in bladder cancer is considered to be a sign of poor prognosis. The present study was performed to analyze the influence of the number of positive lymph nodes on survival and the therapeutic value of lymphadenectomy in pN+patients. METHODS: From January, 1983 to January, 1993, 160 patients aged 39 to 77 years (mean 61.8) underwent radical cystectomy and pelvic lymphadenectomy for carcinoma of the bladder. The records of 122 patients were available for review. The UICC 1978 classification system was used. RESULTS: Cancer-specific mortality was 22.8% (16/70) for pNo patients, 44.4% (4/9) for pN1 patients and 88.9% (16/18) for pN2-4 patients. We obtained the following cancer-specific mortality by stratifying according to T category: 5.4% (2/37) for pNoT1-T3a, 42.4% (14/33) for pNoT3b-T4, 0% (0/2) for pNIT1-T3a, 57.1% (4/7) for pNIT3b-T4 and 88.9% (16/18) for pN2-4T3b-T4. CONCLUSION: The presence of only 1 positive regional lymph node (pN1) appears to worsen patient survival, particularly when the primary tumor is T3b or worse. In these cases cancer-specific mortality after patient discharge increased from 42% for the pNo patients to 57% for the pN1 patients (p > 0.05). Radical cystectomy was highly effective and curative in 95% of T1-T3apNo-1 patients (37/39). The presence of multiple positive lymph nodes carries a very poor prognosis, with 89% of the patients dying at a mean of 12 months.
