Purpose:
Salvage cystectomy is required for some patients with intravesical recurrence after trimodality therapy. We compared postoperative outcomes between salvage cystectomy post-trimodality therapy, primary cystectomy and primary cystectomy with prior history of nontrimodality therapy abdominal or pelvic radiotherapy.
Materials And Methods:
We included 265 patients who underwent radical cystectomy at Massachusetts General Hospital for cT1-T4 bladder cancer between 2003 and 2013. Patients were grouped as salvage cystectomy post-trimodality therapy, primary cystectomy or primary cystectomy with prior history of nontrimodality therapy abdominal or pelvic radiotherapy. Early (≤90 days) and late (>90 days) complications were compared. Disease-specific survival and overall survival were calculated using a Cox regression model, and adjusted survival curves were generated.
Results:
The median followup from the time of cystectomy was 65.5 months. There was no difference in intraoperative and early complications between the groups. The detection of late complications was higher in salvage cystectomy post-trimodality therapy compared to primary cystectomy and primary cystectomy with prior history of nontrimodality therapy abdominal or pelvic radiotherapy (p=0.03). In multivariable Cox regression analysis, salvage cystectomy post-trimodality therapy was associated with a higher incidence of any late (HR 2.3, p=0.02) and major late complications (HR 2.1, p <0.05). There was no difference in disease-specific survival (p=0.8) or overall survival (p=0.9) between the groups.
Conclusions:
Salvage cystectomy post-trimodality therapy for intravesical recurrence post-trimodality therapy has an intraoperative and early complication rate comparable to primary cystectomy and primary cystectomy with prior history of nontrimodality therapy abdominal or pelvic radiotherapy. Salvage cystectomy post-trimodality therapy is associated with a higher risk of overall and major late complications than primary cystectomy. The disease-specific survival and overall survival of patients who require salvage cystectomy post-trimodality therapy are comparable to both groups.
