Following high response rates to systemic therapies like EV Pembro, using radiation for bladder preservation is now questioned. It may constitute overtreatment by radiating a now cancer-free organ, while providing no benefit for the systemic micrometastases that are the primary driver of mortality.

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.

With highly active agents yielding 30% complete response rates, the immediate goal should be to cure more patients by exploring potent combinations upfront. While sequencing minimizes toxicity, an ambitious combination strategy, such as ADC doublets, offers the best chance to eradicate disease and should be prioritized in clinical trials.

In adjuvant bladder cancer trials, ctDNA status is both prognostic and predictive. Patients with positive ctDNA after surgery are at high risk of relapse but benefit from immune checkpoint inhibitors. Conversely, ctDNA-negative patients have a lower risk and derive no benefit, making ctDNA a critical tool to avoid unnecessary, toxic therapy.

With highly effective neoadjuvant therapies now available, the surgeon's role in muscle-invasive bladder cancer is evolving. They are moving from being the primary decider and treater to being a key manager of a 'perioperative bundle,' where their first goal is often to get patients to medical oncology for systemic treatment.

Perioperative enfortumab vedotin-pembrolizumab (EV-Pembro) is surprisingly well-tolerated on a per-cycle basis compared to the traditional GEMSYS chemotherapy regimen. This challenges preconceived notions about the toxicity of this powerful combination, though cumulative toxicity over longer durations remains a key factor.

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.

Expert consensus shows a major paradigm shift: perioperative systemic therapy (like EV-Pembro, scoring 2.9) is the undisputed standard for muscle-invasive bladder cancer. Approaches starting with cystectomy alone now score below 1.8, formally branding them as inferior options.
