Despite excellent responses to systemic therapy in very locally advanced bladder cancer, some experts still advocate for surgery. They argue that even with a complete radiological response, a surgical intervention might represent the only "window of opportunity for cure" by eradicating residual microscopic disease and should remain a key discussion point.
For patients with locally advanced bladder cancer achieving a complete response to potent systemic therapies, experts increasingly argue against consolidative surgery. They believe such effective treatments, a stark contrast to older options, may make the risks of a major operation an unnecessary "overkill" for achieving long-term control.
Achieving a pathologic complete response (path CR) in the bladder after neoadjuvant therapy is a marker of drug efficacy, not a signal to stop treatment. Because patients die from metastatic, not local, disease, a path CR should be seen as a reason to "double down" on the effective systemic therapy to eradicate micrometastases.
For bladder cancer patients with micrometastatic disease, the standard cystectomy requires a significant delay for the operation and recovery. This window may allow unseen metastases to progress, suggesting that upfront, effective systemic therapy is more critical for survival than immediate major surgery.
Despite strong data favoring pre-surgical systemic therapy, a surgeon argues that many patients will continue to undergo surgery first. This is due to real-world factors like surgeons being the point of diagnosis, urgent symptoms requiring rapid intervention, and patient preferences to have the tumor removed immediately.
Contrary to assumption, persistent ctDNA after neoadjuvant therapy does not always mean incurable systemic disease. Surgery alone can clear the ctDNA in roughly half of these patients, suggesting the ctDNA source is often the resectable primary tumor, making cystectomy a potentially curative intervention.
While bladder preservation is a key goal, there is an unavoidable risk. Forgoing definitive local treatment like surgery means a subset of patients will not be cured by systemic therapy alone and will miss their opportunity for a potentially curative operation, a crucial ethical consideration.
As oncology moves toward bladder-sparing approaches, even highly effective systemic therapies won't be enough. To prevent local relapse and truly avoid cystectomy, a bladder-directed component, such as an intravesical therapy, will be a necessary part of the long-term treatment strategy.
High relapse rates (~70%) in surgery-alone arms of recent trials suggest most patients with muscle-invasive bladder cancer (MIBC) already have micrometastatic disease. This reframes the disease, prioritizing early systemic therapy over immediate surgery to achieve control and potential cure.
With therapies like Enfortumab Vedotin + Pembrolizumab (EVPembro) inducing a pathological complete response (PathCR) in 60% of patients, many undergo radical cystectomies only to find no residual cancer. This success rate is driving trials for bladder-sparing approaches like active surveillance.
The success of new treatments like immunotherapy and ADCs leads to more patients achieving a deep response. This high efficacy makes patients question the necessity of a radical cystectomy, a life-altering surgery, creating an urgent need for data-driven, bladder-sparing protocols.
