Study summary

The incidence of breast cancer and its mortality are reduced thanks in particular to early detection.

Often performed after a screening test, stereotactic macrobiopsies are used to characterize abnormalities detected on mammography. This anxiety-inducing and painful examination leads to significant physiological and psychological modifications for these women who logically apprehend the realization of this act.

Faced with this observation, investigators wondered what could be done to improve the experience of the patients during this examination.

Investigators were interested in hypnosis because its effectiveness as a complementary practice has been validated by numerous studies with benefits on pain and stress management.

However, today, there are no convincing results confirming which hypnosis method would be the best to manage patients' anxiety and pain during this examination.

What researchers measure

Primary outcomes

  1. change in anxiety score

    Score (from 20 to 80) measured on the State-Trait Anxiety Inventory for state anxiety (STAI-Y1), how respondent feels right now, at this moment. Total scores can be categorized into five levels: 1. \> 65 (very high), 2. from 56 to 65 (high), 3. from 46 to 55 (medium), 4. from 36 to 45 (low), 5. \< 35 (very low). Higher scores mean a worse outcome.

    Time frame: baseline (pre-intervention, during the intervention, immediatly after the intervetion) and at 8 days

Secondary outcomes

  1. change in anxiety score

    measured on anxiety visual analog scale from 0 (not at all anxious) to 8 (extremely anxious)

    Time frame: baseline (pre-intervention, during the intervention, immediatly after the intervetion) and at 8 days

  2. change in pain score

    measured on pain visual analog scale from 0 (no pain) to 10 (worst pain)

    Time frame: baseline (pre-intervention, during the intervention, immediatly after the intervetion) and at 8 days

  3. patient examination experience

    measured on satisfaction visual analog scale from 0 (poor experience quality) to 10 (very good experience quality)

    Time frame: baseline (immediately after the intervention)

  4. staff examination experience

    measured on satisfaction visual analog scale from 0 (poor experience quality) to 10 (very good experience quality)

    Time frame: baseline (immediately after the intervention)

  5. anxiety score

    STAI-Y2 (score from 20 to 80 measured on the STAI for trait anxiety), how respondent generally feel Total scores can be categorized into five levels: 1. \> 65 (very high), 2. from 56 to 65 (high), 3. from 46 to 55 (medium), 4. from 36 to 45 (low), 5. \< 35 (very low). Higher scores mean a worse outcome.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Oct 2022 (actual). Primary completion is estimated for Dec 2024, 26 months after the start.

Of 2,662 non-industry interventional studies with no phase under Breast Neoplasms, half reached primary completion within 33 months of starting (the median), counting those still running; a quarter within 16 and three quarters within 66. This study's planned 26 months is below that.

Counting every sponsor, half of 2,772 studies reached it within 33 months; a quarter within 15 and three quarters within 66.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 19, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
