Debate: Neoadjuvant Chemotherapy Prior to Cystectomy | Con Argument – Summary:
Michael S. Cookson, MD, MMHC, argues that neoadjuvant chemotherapy (NAC) is not appropriate or necessary for all patients with muscle invasive bladder cancer (MIBC) prior to cystectomy. Instead, physicians should use a selective approach to NAC to avoid unnecessary harms, toxicities, and delays in local therapy.
This presentation is the “con” or negative installment of a debate over the use of neoadjuvant chemotherapy prior to cystectomy for MIBC. The rebuttal to this argument is “Debate: Neoadjuvant Chemotherapy Prior to Cystectomy | Pro Argument” by Daniel P. Petrylak, MD.
Abstract:
Level 1 evidence from the SWOG 87-10 trial does demonstrate improved survival with NAC in patients with MIBC undergoing cystectomy. The most dramatic improvement in this study was in patients with locally advanced disease.
However, there is no proven benefit to non-cisplatin based NAC in bladder cancer. This means patients who are ineligible, for reasons such as poor performance status, impaired renal function, or comorbidities, or may not tolerate cisplatin must proceed to cystectomy or seek a clinical trial. Physicians must carefully screen patients for cisplatin eligibility based on consensus factors such as glomerular filtration rate (GFR) and Eastern Cooperative Oncology Group (ECOG) Performance Status.
Currently, European Association of Urology (EAU) guidelines recommend platinum-based NAC for invasive tumors. However, they recommend against NAC when there is a contraindication, and to discontinue NAC in cases of progression.
Another drawback of NAC is that not all tumors will respond, as certain molecular subtypes resist platinum altogether, and patients with “secondary,” as opposed to “primary,” MIBC have lower response rates. Furthermore, up to a third of patients undergoing NAC will have Grade 3 and 4 toxicity.
For these reasons, a selective approach to identify patients who will do well with radical cystectomy alone and those who will benefit from NAC is essential. A group from MD Anderson Cancer Center has reported on refining this patient selection process based on clinical risk-factors.
