Is this trial a fit for you?

Likely a good fit

Ideal candidates are genetically female adults 18–65 years old undergoing primary or revision breast augmentation or reconstruction with Luna implants and willing to adhere to follow-up visits.

Probably not a fit

Patients who are not likely to benefit include those outside the age range, with BMI over 35, or who are not receiving Luna implants or not completing follow-up.

What this trial studies

This is an observational, non-comparative study tracking the durability of Eurosilicone Luna mammary implants over a 10-year period. It aims to measure the frequency of implant rupture and Baker III-IV capsular contracture in women undergoing primary or revision augmentation or reconstruction. Participants will be female between 18 and 65 years old who receive the Luna implants and agree to long-term follow-up. Data will be collected from surgical procedures and follow-up visits to assess implant performance and safety. No randomized or comparative interventions are performed beyond standard surgical care.

Why it matters

Potential benefit: If successful, the study could help define long-term safety and durability of Luna implants for patients and surgeons considering reconstruction or augmentation.

How similar studies have gone: Previous studies in silicone breast implants have reported variable long-term outcomes; this study adds real-world, post-market data for Luna implants.

Inclusion Criteria:

* The target population includes subjects undergoing augmentation or reconstructive breast implant surgery in which the Eurosilicone Luna mammary implant is recommended.

Inclusion criteria are:

1. Genetic female subjects aged between 18 and 65 years old.
2. Subjects who underwent single or bilateral breast implantation with the study device for one of the following reasons:

i. Primary breast reconstruction following mastectomy (both for one-stage or two-stage surgeries, including patients with previous radiotherapy and who have ADMs (synthetic or natural).

ii. Primary breast augmentation (cosmetic surgery) with or without mastopexy iii. Breast revision surgery with or without mastopexy c) Subjects who have received a Eurosilicone Luna implant. d) Subjects who have provided informed consent and can adhere to the requirements of follow-up appointments as per the study protocol.

Exclusion criteria are:

1. Subjects with a BMI \>35.
2. Subjects with autoimmune disease, lung fibrocystic disease, conditions that interfere with wound healing and blood clotting, a weakened immune system, reduced blood supply to the breast tissue or any other condition for which breast implants are contraindicated.
3. Subjects who have participated in a clinical study which involve chemical or drug study within 3 months prior to surgery, with the exception of subjects who are participating in breast cancer-related clinical studies.
4. Subjects with insufficient tissue covering due to either radiation damage on the chest wall, tight thoracic skin grafts or radical resection of the pectoralis major muscle.
5. Subjects who, in the Investigator's clinical opinion, have existing local or metastatic carcinoma of the breast that is unlikely to be fully excised at the time of insertion of the breast implant.
6. Subjects with known previous history of a sensitivity to silicone who, in the opinion of the Investigator, are unsuitable for surgery.
7. Subjects with an active infection who are unsuitable for surgery unless, in the opinion of the investigator, they are treated and cleared by the investigator.
8. Subjects with a history of abscesses anywhere in the body who, in the opinion of the Investigator, are unsuitable for surgery.
9. Subjects with a known history of compromised wound healing.
10. Subjects who, in the opinion of the Investigator, have an existing condition that would compromise their participation and follow-up in this study.
11. Women who are pregnant and/or current breast feeders who do not stop breast feeding within 3 months of getting breast implants.
12. Patients who have local recurrence or metastatic carcinoma at the time of insertion of breast implant.
