Feasibility of HISA During TURBT for NMIBC

8. September 2026 aktualisiert von: 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

Studienübersicht

Detaillierte Beschreibung

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.

Waffen und Interventionen

Teilnehmergruppe / Arm
Intervention / Behandlung
Kein Eingriff: No HISA
The control arm (no HISA) will consist of standard intraoperative care including bladder irrigation with normothermic saline during TURBT.
Experimental: 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.

Zeitfenster
Patient Recruitment
Zeitfenster: 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
Zeitfenster: 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.

Overall Cancer-related Quality of Life and General Treatment Effects

Quality of life will be assessed at the preoperative visit and follow-up visits at 2-weeks, 3 months, and 6 months using the EORTC QLQ Core Questionnaire (EORTC QLQ-C30, version 3.0).
From TURBT to 6 months after TURBT
Recurrence of NMIBC
Zeitfenster: 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
Zeitfenster: 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.
