Study summary

This study is

  • to analyze whether more changes in melanocytic nevi (MN) occur in women during and after pregnancy compared to non-pregnant women of the same age
  • and to analyze psychological effects of total body mapping and dermoscopic examination assisted by artificial intelligence during pregnancy.
Read the detailed description

Melanocytic nevi (MN) are believed to undergo macroscopic and dermoscopic alterations during pregnancy. Possible changing features previously observed include color, pigment network, size, vascularization and the emerging of dots and globules. Recent studies have reported of melanoma being associated with increased mortality in pregnant women when compared to non-pregnant women. The new FotoFinder® ATBM master device provides the combination of total body mapping with deep learning-driven body scan algorithm which identifies all pigmented skin lesions of the body surface by pattern recognition software and supplies a risk assessment score (0.0-1.0; 0 indicating no suspicion for melanoma, 1 indicating a high suspicion for melanoma).

This study is

  • to analyze whether more changes in melanocytic nevi (MN) occur in women during and after pregnancy compared to non-pregnant women of the same age
  • and to analyze psychological effects of total body mapping and dermoscopic examination assisted by artificial intelligence during pregnancy.

Interventions

  • Otherstandard-of-care clinical skin examination

    inspection of melanocytic nevi by dermatologist

  • Diagnostic testskin assessment with the 2D FotoFinder ATBM master system

    The FotoFinder® ATBM master device provides the combination of total body mapping with deep learning-driven body scan algorithm which identifies all pigmented skin lesions of the body surface by pattern recognition software and supplies a risk assessment score (0.0-1.0; 0 indicating no suspicion for melanoma, 1 indicating a high suspicion for melanoma).The integrated software analyzer scores regarding malignancy probability of the moles (FotoFinder® score: 0.0-1.0) will be collected.

  • Otherdata collection by participant questionnaire

    At baseline, the participants will complete a questionnaire concerning their previous exposure to sun, their current sun-related protective behaviours, their history of skin check frequency and skin cancer at baseline. Additionally, in each consultation newly-created study-specific questions concerning the participants' examination experience, the sun-related protective behaviours and worries about skin cancer throughout the study will be investigated.

What researchers measure

Primary outcomes

  1. Change in macroscopic aspect of melanocytic nevi

    Change in macroscopic aspect of melanocytic nevi

    Time frame: for pregnant women: Visit 1 (between the 12th and 16th week of pregnancy), Visit 2 (between the 29th and 33rd week of pregnancy), Visit 3 (between 8 to 12 weeks after delivery). Non- pregnant women: Visit 1, Visit 2 (17 to 21 weeks after Visit 1)

  2. Change in mole analyzer score with the 2D FotoFinder ATBM master system

    mole analyzer score (0.0-1.0; 0 indicating no suspicion for melanoma, 1 indicating a high suspicion for melanoma)

    Time frame: for pregnant women: Visit 1 (between the 12th and 16th week of pregnancy), Visit 2 (between the 29th and 33rd week of pregnancy), Visit 3 (between 8 to 12 weeks after delivery). Non- pregnant women: Visit 1, Visit 2 (17 to 21 weeks after Visit 1)

Secondary outcomes

  1. Change in number of new malignant melanoma

    Change in number of new malignant melanoma

    Time frame: for pregnant women: Visit 1 (between the 12th and 16th week of pregnancy), Visit 2 (between the 29th and 33rd week of pregnancy), Visit 3 (between 8 to 12 weeks after delivery). Non- pregnant women: Visit 1, Visit 2 (17 to 21 weeks after Visit 1)

  2. Change in psychological impact of skin cancer screening by descriptive analyzes of participants questionnaire

    Change in psychological impact of skin cancer screening by descriptive analyzes of participants questionnaire (investigating the subjective examination experience, the impact on skin cancer worries and the participants' sun protection and self-inspection behaviour).

    Time frame: for pregnant women: Visit 1 (between the 12th and 16th week of pregnancy), Visit 2 (between the 29th and 33rd week of pregnancy), Visit 3 (between 8 to 12 weeks after delivery). Non- pregnant women: Visit 1, Visit 2 (17 to 21 weeks after Visit 1)

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 May 18, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
