Feasibility of HISA During TURBT for NMIBC

2026年9月8日 更新者:Michael Stencel、CAMC Health System

A Pilot Study Using Hyperthermic Irrigation Followed by Intravesical Chemotherapy in Patients With Low- to Intermediate-Risk Non-Muscle Invasive Bladder Cancer

The goal of this prospective pilot study is to evaluate the safety and feasibility of using heated saline during bladder tumor surgery in patients with non-muscle invasive bladder cancer.

The main questions it aims to answer are:

Can heated saline be given during bladder tumor removal surgery safely?

Does using heated saline keep the bladder tumor from coming back?

Researchers will compare the heated saline to room temperature saline to see if the heated saline works to prevent the bladder tumor from coming back.

Participants will:

  • Have heated saline or room temperature saline during bladder tumor surgery
  • Visit the clinic at 2 weeks, 3 and 6 months after bladder tumor surgery
  • Complete questionnaires about quality of their life and symptoms before and after surgery
  • Provide urine samples to test your urine at each visit before and after surgery
  • To have a cystoscopy to check your bladder for tumors

調査の概要

詳細な説明

Non-muscle invasive bladder cancer (NMIBC) represents 75% of bladder cancer cases and recurs in up to 79% of patients. West Virginia carries disproportionately high bladder cancer incidence due to smoking, aging population, and occupational exposures. High recurrence requires frequent cystoscopy and intravesical therapy, creating a burden for rural Appalachian patients. New strategies to reduce recurrence and treatment are urgently needed.

Hyperthermic intravesical chemotherapy improves drug penetration and tumor cell sensitivity. However, the benefit of applying hyperthermic saline intraoperatively during resection of the bladder tumor is unknown. In this randomized, two-arm study, we will randomize 40 patients with low-risk appearing NMIBC to normothermic and hyperthermic saline irrigation during bladder tumor resection. Hyperthermic irrigation will be delivered at 42 ± 2° Celsius using the Stryker Thermaclear FluidSmart system. All patients will receive standard postoperative gemcitabine instillation. Follow-up visits will occur at 2 weeks, 3 and 6 months. The primary goal is feasibility, defined as 80% protocol adherence to hyperthermic irrigation. Secondary goals include safety, logistics, and patient retention. Additional outcomes include recurrence, adverse events, and patient-reported quality-of-life scores.

武器と介入

参加者グループ / アーム
介入・治療
介入なし:No HISA
The control arm (no HISA) will consist of standard intraoperative care including bladder irrigation with normothermic saline during TURBT.
実験的:HISA
The intervention arm (HISA) will be treated in the same way as the control arm with the addition of administering hyperthermic (42.0 ± 2°C) intravesical saline during the TURBT.
The intervention arm (HISA) will be treated in the same way as the control arm with the addition of administering hyperthermic (42.0 ± 2°C) intravesical saline during the TURBT. Bladder irrigation with 1g of gemcitabine will be delivered in the immediate postoperative setting. The Thermaclear FluidSmart Fluid management system (Stryker, MI) will be used to administer and irrigate the bladder with normothermic or hyperthermic intravesical saline during the TURBT.

主要な結果の測定

結果測定
メジャーの説明
時間枠
Patient Recruitment
時間枠:one year
The primary outcome will be patient recruitment. Patient recruitment will be the number of patients recruited divided by the total number of eligible patients.
one year
Protocol Adherence for HISA Treatment
時間枠:one year
Protocol adherence will be assessed per case. Full adherence is defined as: (1) assigned saline used; (2) temperature maintained at 42.0 ± 2.0°C for ≥80% of intended exposure; (3) delivery of hyperthermic saline occurred during the specified operative window, and (4) postoperative instillation of 1g gemcitabine for 60 minutes.

To assess postoperative complications, adverse events, and readmission rates at 30- and 90-days. Adverse events will be monitored during the study for up to 90 days for each patient, assessed and graded using the Common Terminology Criteria for Adverse Events (CTCAE) version 5.

From TURBT to 6 months after TURBT
Recurrence of NMIBC
時間枠:From time of TURBT to 6 months after TURBT
The proportion of patients with recurrence of NMIBC will be determined. Recurrence will be defined as the percentage of patients with the reappearance of NMIBC tumor(s) within the bladder following transurethral resection of bladder tumor (TURBT). The event will be defined as the earliest date of recurrence as determined using the date of cystoscopy, biopsy, or cytology, whichever occurs first.
From time of TURBT to 6 months after TURBT
Survival of NMIBC Patients
時間枠:From time of TURBT to 6 months after TURBT
Survival will be defined as the percentage of patients who have survived after TURBT without any recurrence or death from any cause. The event will be defined as the length of time until cancer recurrence or death from any cause using the date of cystoscopy, biopsy, or death certificate date whichever occurs first.
