About this study

Official title: Surgery Combined With IMRT-IGRT in Locally-advanced Prostate Cancers

Standard treatment of locally-advanced prostate cancers consists in the association of radiotherapy of prostate and seminal vesicles (SV) and androgen deprivation (AD) for 3 years. This treatment is usually preceded by pelvic lymphadenectomy to assess the possible extension to lymph nodes of prostatic cancer and to avoid irradiating the pelvis in case of no lymph node involvement. However, radiotherapy leads usually to about 30% of grade ≥2 risk of bladder and/or rectal toxicity. This risk particularly depends on the radiation volume. In the aim of lowering the toxicity, the treatment in this study will associate:

  • pelvic lymph node dissection and resection of seminal vesicles, allowing decreasing the radiation target volume to the prostate only (and not to irradiate the SV);
  • a high-precision radiotherapy technique combining Intensity Modulated Radiation Therapy (IMRT) and Image-Guided Radiation Therapy (IGRT).
Read the detailed description

This study targets non metastatic prostatic locally-advanced adenocarcinomas which are at high risk of both local progression and metastases. The standard treatment of these tumours associates external beam radiation therapy (EBRT) and 3 years of androgen deprivation (AD) with LH-RH analogue. In the absence of AD and mainly when prostate specific antigen (PSA) is >10 ng/ml, several randomized studies have shown that high doses of EBRT increase biochemical control. Nevertheless, escalating the doses of radiation significantly increases the risk of rectal and/or urinary toxicities. In order to lower the toxicity of irradiation in locally-advanced prostate cancers, and to improve the quality of life of patients, this study aims at decreasing the volume of irradiated healthy tissues. To carry out this objective, we will use a double strategy:

  • Limiting the target volume to prostate only by removing seminal vesicles at the time of lymph node dissection,
  • Using a technique of high-precision radiation combining Intensity Modulated Radiation Therapy (IMRT) and Image-Guided Radiation Therapy (IGRT).

Based on the literature, we may assume a toxicity rate of 30% during the three years of hormonotherapy with standard treatment (i.e. without removing seminal vesicles). We make the hypothesis of a 20% absolute reduction of toxicity with our protocol.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Surgery combined with IMRT-IGRTProcedure or surgery

    Patients will have surgery consisting in extensive pelvic dissection and ablation of seminal vesicles. Surgery will be followed by prolonged hormonotherapy (3 years) associated, after 2 months, with prostatic only irradiation.

    Measured: 3 years

  3. Erectile troubles

    Assessed with erectile troubles questionnaire (IIEF-5)

    Measured: 3 years

  4. Onset of biological signs evocating a recidive

    Assessed with PSA levels

    Measured: 3 years

  5. Onset of clinical signs evocating a recidive

    Measured: 3 years

  6. Specific and global survival

    Measured: 3 years

  7. Rate of bladder and/or rectal grade ≥2 toxicity (CTCAE V4.0) (early toxicity)

    Rate of late bladder and/or rectal grade ≥2 toxicity (CTCAE V4.0) observed 6 months after the beginning of the radiotherapy.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Surgery combined with IMRT-IGRT in people with Prostate Cancer and Prostate Adenocarcinoma, run by Rennes University Hospital at 2 sites in France.

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 16 inclusion and 3 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: finished, as of the sponsor's last update on 19 Dec 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in France. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Rate of bladder and/or rectal grade ≥2 toxicity (late toxicity) (time frame: between 6 months and 3 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 19 Dec 2018.
