Background
The efficacy of neoadjuvant chemotherapy (NAC) for muscle-invasive bladder cancer (BCa) was established primarily with methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC), with complete response rates (pT0) as high as 38%. However, because of the comparable efficacy with better tolerability of gemcitabine and cisplatin (GC) in patients with metastatic disease, GC has become the most commonly used regimen in the neoadjuvant setting.
Objective
We aimed to assess real-world pathologic response rates to NAC with different regimens in a large, multicenter cohort.
Design, setting, and participants
Data were collected retrospectively at 19 centers on patients with clinical cT2–4aN0M0 urothelial carcinoma of the bladder who received at least three cycles of NAC, followed by radical cystectomy (RC), between 2000 and 2013.
Intervention
NAC and RC
Outcome measurements and statistical analysis
The primary outcome was pathologic stage at cystectomy. Univariable and multivariable analyses were used to determine factors predictive of pT0N0 and ≤pT1N0 stages.
Results and limitations
Data were collected on 935 patients who met inclusion criteria. GC was used in the majority of the patients (n = 602; 64.4%), followed by MVAC (n = 183; 19.6%) and other regimens (n = 144; 15.4%). The rates of pT0N0 and ≤pT1N0 pathologic response were 22.7% and 40.8%, respectively. The rate of pT0N0 disease for patients receiving GC was 23.9%, compared with 24.5% for MVAC (p = 0.2). There was no difference between MVAC and GC in pT0N0 on multivariable analysis (odds ratio: 0.89 [95% confidence interval, 0.61–1.34]; p = 0.6).
Conclusions
Response rates to NAC were lower than those reported in prospective randomized trials, and we did not discern a difference between MVAC and GC. Without any evidence from randomized prospective trials, the best NAC regimen for invasive BCa remains to be determined.
Patient summary
There was no apparent difference in the response rates to the two most common presurgical chemotherapy regimens for patients with bladder cancer.
A significant proportion of men suffer side effects and are acknowledged to have unmet physical, functional and psychological needs after prostate cancer treatment. A nurse-led survivorship programme was implemented at Newcastle upon Tyne Hospitals NHS Foundation Trust for men with prostate cancer. This article describes implementation of the model and presents the results of an early evaluation to assess its impact. In the first 6 months 169 men (90% of those invited) engaged in the survivorship programme. Holistic needs assessments in particular were found to be invaluable for addressing individual men's needs and signposting them to relevant services. Collaboration between existing organisations and initiatives across primary and secondary care resulted in the establishment of a comprehensive network of services available to men on the programme. The nurse-led Newcastle survivorship model has been able to deliver individualised survivorship care with a high satisfaction rating within routine NHS practice.
pTa/Tis/T1N0 and pT0N0 stage on the final cystectomy specimen are strong predictors of survival in patients treated with neoadjuvant chemotherapy and radical cystectomy. We did not discern a statistically significant difference in overall survival when comparing these 2 end points.
