NCT05031962

Brief Summary

The general objective of the study is to confirm the medium/long-term safety and clinical performance of the CELLIS Breast membranes used in breast reconstruction and to identify emerging risks in comparison to clinical data related to other treatment modalities. The present study will be a prospective, multicentric, non-randomized and non-controlled trial involving 112 patients followed for 24 months. The study will be conducted in France in 7 investigational centres.

Outcome Measures

Primary Outcomes (1)

  • Rate of adverse events. Main complications of interest: infection, cellulitis, seroma, hematoma, skin flap-nipple necrosis, delayed wound healing, wound dehiscence, red breast syndrome, capsular contracture, implant related

    Percentage

    From the surgical procedure throughout the entire 24-month follow-up period

Secondary Outcomes (6)

  • Patient aesthetic evaluation evaluated by Visual Analog Scale (VAS). The suppleness of the reconstruction will be evaluated (natural-hard): VAS score from 1 to 10 (1=very bad suppleness, breast hard; 10=excellent suppleness-natural breast).

    At the 3, 12 and 24-month follow-up visits

  • Surgeon aesthetic evaluation: satisfaction related to the quality of the reconstruction (very good, good, fair, bad), suppleness (Visual Analog Scale score from 1 to 10 with 10=excellent suppleness) and symmetry (very good, good, fair, bad).

    At the 3, 12 and 24-month follow-up visits

  • Patient-reported pain using a visual analogue scale (VAS) scored from 0 to 10 (0=no pain; 10=worse pain).

    At the 10-day, 30-day, 3-month, 12-month and 24-month follow-up visits

  • Patient analgesics consumption

    At the 10-day, 30-day, 3-month, 12-month and 24-month follow-up visits

  • Quality of life (QoL) by the use of the SF-36 questionnaire.

    At baseline and at 24 month

  • +1 more secondary outcomes

Sampling MethodProbability Sample
Study Population

Constitution and follow-up of a consecutive cohort of patients operated with the CELLIS Breast membranes based on the usual practices, the indication and the inclusion-exclusion criteria.

You may qualify if:

  • Patient aged ≥18 years,
  • Patient with an indication of breast reconstruction after mastectomy (therapeutic or prophylactic),
  • Patient being informed of her participation to the study and of the follow-up visits, and having no objection to the clinical data collection and medical file access,

You may not qualify if:

  • Patient with known hypersensitivity to porcine materials,
  • Patient with an existing infection at the site of implantation,
  • Patient having refused to participate to the study,
  • Patient refusing to return for the follow-up visits,
  • Patient who is pregnant.
