Results of treatment in patients with urinary bladder cancer metastasizing to regional lymph nodes

Abstract

The data of 668 radical cystectomies were used to study the results of treatment in 151 (22,6%) patients with urinary bladder cancer (UBC) metastasizing to the regional lymph nodes and to evaluate the impact of lymphodissection extent on the detection rate of metastases and on survival.

In UBC, routine lymphodissection significantly increases the detection rate of regional metastases as compared with limited lymphodissection from 17,8 to 24,8% (p = 0,04). Expanded lymphodissection in patients with UBC with regional metastases could significantly increase overall 5-year survival (p = 0,006).

In patients with UBC metastasizing to the regional lymph nodes, the survival rates found after cystectomy using the currently available urine derivation techniques suggest that orthotopic urine derivation may be used in this group of patients after radical operation. Among all factors influencing survival in such patients, the degree of involvement of regional lymph nodes (p = 0,04) and the extent of lymphodissection (p = 0,02) are of independent prognostic value.
