Trial summary

A radical cystectomy + extended pelvic lymph node dissection is considered to be the treatment of choice for patients with muscle invasive bladder cancer (MIBC). Despite this aggressive treatment the outcome is poor and ultimately, 30% of the patients with ≥pT3 tumors develop a pelvic recurrence. Read more about this study

About this study

Official title: Adjuvant Radiotherapy After Cystectomy for Patients With Muscle Invasive Bladder Cancer: a Phase II Trial.

A radical cystectomy + extended pelvic lymph node dissection is considered to be the treatment of choice for patients with muscle invasive bladder cancer (MIBC). Despite this aggressive treatment the outcome is poor and ultimately, 30% of the patients with ≥pT3 tumors develop a pelvic recurrence. One- and 2-years survival for patients developing a local recurrence after cystectomy is only 8% and 3% respectively, with a median survival of <4 months. For patients with lymph node recurrence prognosis is somewhat better, but nevertheless still disappointing with reported 1- and 2 years survival of 42% and 11% respectively. The investigators hypothesize that an earlier implementation of external beam radiotherapy (EBRT) i.e. in the adjuvant setting, will prevent local and lymph node recurrence and improve disease free- and overall survival as local recurrence is linked to the development of distant metastasis. Adjuvant EBRT was tested in a prospective randomized trial and resulted in a 20% increase in 5-year disease free survival. Despite those impressive results, severe intestinal toxicity rates hampered the enthusiasm to use adjuvant EBRT, till now. In the last decade, great technological advancements in EBRT planning, such as intensity modulated arc therapy (IMAT), and positioning have been realised. This has resulted in a better coverage of the target volume while sparing normal tissue (mainly small bowel) and in a more precise delivery of the EBRT. Therefore, it is desirable to reconsider the use of adjuvant EBRT in selected MIBC patients.

Read the detailed description

The investigators plan to perform a prospective phase 2 study including 76 patients.

Radiation up to a median dose of 50 Gy in 25 fractions will be delivered with IMAT to the pelvic lymph node regions. If there is a positive surgical margin, the operative bladder bed will be included in the radiation field. A simultaneous integrated boost to 64 Gy to the positive lymph nodes will be delivered. Pathological evaluation on cystectomy specimen includes: tumor stage and grade, area of necrosis (absolute and relative), micro vessel density, epidermal growth factor receptor.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. change from baseline in acute Radiation Therapy Oncology Group (RTOG) toxicity

    Measured: last day of radiotherapy, 1 month and 3 months after last day of EBRT

Secondary outcomes (4)
  1. change from baseline in late RTOG toxicity

    Measured: at 6,9, 12, 18 and 24months after last day of EBRT

  2. change from baseline in local control

    Measured: at 6,9, 12, 18 and 24months after last day of EBRT

  3. disease free survival

    Measured: at 6,9, 12, 18 and 24months after last day of EBRT

  4. overall survival

    Measured: at 6,9, 12, 18 and 24months after last day of EBRT

Questions about this trial

What is this clinical trial studying?

A study testing Adjuvant EBRT in people with Toxicity, run by University Hospital, Ghent at 1 site in Belgium.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 23 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Belgium. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

change from baseline in acute Radiation Therapy Oncology Group (RTOG) toxicity (time frame: last day of radiotherapy, 1 month and 3 months after last day of EBRT). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02397434, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Oct 2023.
