Immediate Chemotherapy Following Resection for High-Risk Non-Muscle-Invasive Bladder Cancer (HIGCrecur)

March 16, 2025 updated by: Shuxiong Zeng, Changhai Hospital

Impact of Immediate Cisplatin/Gemcitabine Chemotherapy Following Resection for High-Risk Non-Muscle-Invasive Bladder Cancer: an Open-label, Single-arm, Prospective Trial

Residual tumors after transurethral resection of bladder tumors (TURBT) range from 17-70%, and floating tumor cells from traditional segmental resection may lead to recurrence if they re-implant in the bladder wall. Immediate systemic chemotherapy post-surgery aims to eliminate microlesions promptly and minimize recurrence risk, yet its safety and efficacy require further exploration. This prospective, single-arm study delves into evaluating the efficacy and safety of immediate postoperative systemic chemotherapy in patients with suspected high-risk non-muscle-invasive bladder cancer.

Detailed Description

Bladder cancer ranks as the ninth most prevalent cancer globally, with urothelial carcinoma being the primary form, leading to over 220,000 deaths annually. While 70-75% of bladder cancer cases initially present as non-muscle invasive bladder cancer (NMIBC) with favorable prognoses, the recurrence rate can reach 78% within five years post-standard treatment. The primary objective of transurethral resection of bladder tumors (TURBT) is to accurately diagnose and completely eliminate all visible lesions, as the quality of resection significantly impacts prognosis. However, a systematic review reveals a notable risk of residual tumor post-initial resection. For individuals with high-risk non-muscle invasive bladder cancer (NMIBC), EAU guidelines recommend a follow-up resection 2-6 weeks later. Clinical trials have demonstrated that administering a single chemotherapy session within 24 hours of the initial resection can lower recurrence rates. This approach may work by eradicating floating tumor cells, ablating residual tumor cells, and addressing overlooked small tumors. Gemcitabine and cisplatin (GC) have good efficacy and tolerance in patients with bladder cancer and have become the most commonly used regimen in the neoadjuvant treatment of bladder cancer. There is currently a lack of strong evidence that GC chemotherapy 24 hours after surgery can safely and effectively reduce the risk of recurrence in suspected high-risk NMIBC cases. Our goal is to conduct a prospective clinical trial to investigate the feasibility of this treatment method by evaluating the incidence of adverse events and recurrence-free survival in this group of patients by administering systemic chemotherapy 24 hours after TURBT for patients with suspected high-recurrence bladder cancer.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Experimental: Immediate GC chemotherapy infusion
For enrolled patients receiving immediate cisplatin/gemcitabine chemotherapy via intravenous infusion within 24 hours post transurethral resection of bladder tumor (TURBT), fluid samples were collected before and after TURBT, as well as post-chemotherapy, for UroCAD testing to assess chromosomal instability status and evaluate postoperative tumor residual changes. Subsequently, following EAU guidelines, patients were administered 1 year of intravesical Bacillus Calmette-Guérin (BCG) induction and maintenance therapy, with regular imaging studies and cystoscopic examinations for follow-up to assess the patients' pathological response status.
Procedure: Immediate postoperative chemotherapy
Systemic chemotherapy with cisplatin/gemcitabine intravenous infusion within 24 hours after TURBT
