The impact of treatment modality on survival in patients with clinical node-positive bladder cancer: results from a multicenter collaboration.

To assess the impact of perioperative chemotherapy on survival in cN+ BCa patients and analyze it according to the pN status.

A retrospective analysis was conducted on 639 BCa patients with cTanyN1-3M0 BCa treated with radical cystectomy (RC) and bilateral lymph node dissection (LND) with or without perioperative chemotherapy in ten tertiary referral centers from 1990 to 2017. Selected cN+ patients received induction chemotherapy (IC), whereas adjuvant chemotherapy (ACT) was delivered to selected pN+ patients. Univariable and multivariable Cox regression analyses were used to predict overall mortality (OM) after surgery, adjusting for clinicopathological confounders. Kaplan-Meier analyses assessed OM according to the treatment modality.

Overall, 356 (56%) patients were treated with surgery alone, 155 (24%) with IC followed by surgery, and 128 (20%) with ACT following surgery. Over a median follow-up of 25 months, 316 deaths were recorded. At univariable analysis, patients treated with IC and surgery had lower OM both considering cN+ [hazard ratio (HR) 0.65, 95% confidence interval (CI) 0.49-0.87, p = 0.004] and cN+pN- patients (HR 0.61, 95% CI 0.37-0.99, p = 0.05) compared to those treated with surgery alone. cN+pN+ patients treated with ACT experienced lower OM compared to those treated with IC or surgery alone at multivariable analysis (HR 0.40, 95% CI 0.22-0.74, p = 0.003).

Patients with cTany cN+ cM0 BCa benefit more in terms of OS when treated with IC followed by RC + LND compared to RC + LND alone, regardless of LNMs at final histopathology examination. More data are needed to assess the role of ACT in the management of cN+ patients.
