PURPOSE: Lymph node metastasis in patients who undergo radical cystectomy for bladder transitional cell carcinoma is considered a poor prognostic factor. However, patients with minimal lymph node involvement likely have a better outcome than those with extensive disease. We examined outcomes in patients with low volume lymph node metastasis and identified variables associated with disease recurrence. MATERIALS AND METHODS: Our institution maintains a database of 1,600 patients with bladder transitional carcinoma who underwent radical cystectomy from 1971 to 2005 with intent to cure. All patients with low volume lymph node metastasis, defined as 1 or 2 positive lymph nodes, without concomitant distant metastasis were included in study. RESULTS: A total of 181 patients were identified. Median followup was 12.8 years, during which 96 patients experienced recurrence. Estimated 5 and 10-year recurrence-free survival was 43.8% and 40.9%, respectively. Multivariate analysis indicated that pathological stage/subgroup (RR 1.733, p = 0.015), lymph node density (RR 1.935, p = 0.014) and adjuvant chemotherapy (RR 0.538, p = 0.004) were significant independent predictors of recurrence-free survival. CONCLUSIONS: A considerable proportion of patients with low volume lymph node metastasis in our cohort remained free of recurrence during followup. Extravesical tumor extension and lymph node density greater than 4% were associated with a higher recurrence risk and adjuvant chemotherapy was associated with a lower risk. Although some patients with low volume lymph node metastasis may be cured by surgery alone, these data support adjuvant chemotherapy in these patients.
