Introduction:
We report the oncological outcome after laparoscopic radical cystectomy (LRC) and standard laparoscopic pelvic lymph node dissection (PLND) without neoadjuvant or adjuvant therapy in the treatment of bladder cancer with a median follow-up of 32 months.
Materials And Methods:
From September 2006 to January 2011, 40 consecutive patients underwent an LRC and standard laparoscopic PLND, and were included in this prospective observational cohort study. No patient received neoadjuvant or adjuvant therapy. Demographic, perioperative, complication, histopathologic and survival data were collected and analyzed.
Results:
The 2002 TNM staging for the tumors were: pT0, 4 cases; pTis, 5 cases; pT1, 4 cases; pT2, 7 cases; pT3, 13 cases; pT4, 7 cases. Positive surgical margins were reported in 3 patients (7.5%) and lymph node involvement in 9 patients (23.7%). No patient was lost to follow-up. The overall, cancer-specific and recurrence-free survival rates were 53, 73 and 70% with a median follow-up of 32 months. Eleven patients (27.5%) died of metastatic disease or local recurrence. Nonorgan-confined disease (≥pT3) and primary lymph node involvement (pN+) were significantly associated with worse overall, cancer-specific and recurrence-free survival rates.
Conclusion:
We report acceptable mid-term and promising long-term oncological outcome after LRC and standard laparoscopic PLND without neoadjuvant or adjuvant therapy.
