Study Details

Study Description

Brief Summary

The placement of a small silicone prosthesis in the partial defects generated by conservative breast cancer surgery improves the aesthetic result, compared to the usual surgical technique, in a safe and reproducible way and compatible with adjuvant treatments. It could also potentially improve the quality of life of patients

Condition or Disease Intervention/Treatment Phase
  • Device: Silicone prosthesis
  • Procedure: Usual practice

Detailed Description

Conservative surgery in breast cancer is performed more than 50% of cases, however, aesthetic results are suboptimal, because reconstructive techniques are performed in less than 5% of them. Objective: To demonstrate that the placement of a silicone prosthesis in partial defects generated by breast cancer conservative surgery improves the aesthetic result, compared to the usual surgical technique, safely, reproducibly and compatible with adjuvant treatments.

Methodology: Prospective randomized clinical trial, controlled with blind evaluator. Inclusion criteria: Women with breast cancer candidates for conservative surgery. Intervention: In the cases the study technique will be carried out consisting in the filling of the defect with a silicone prosthesis of size adjusted to it (2-4cm). Controls: usual surgical procedure. Main result variable: aesthetic results (visual analog scale) according to the patient, surgeon and blind external evaluator. Secondary variables: surgical complications, local complications derived from adjuvant treatments, rate of local recurrence, rate of reintervention due to affected margins, behavior in mammographic follow-up, professional satisfaction and impact on quality of life.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Group intervention: Silicone prothesis

Breast cancer conservative surgery will be performed by removing the tumor according to the usual technique and then the defect generated will be filled with a silicone prosthesis of the same size. Said prosthesis will be covered with fat and subcutaneous cellular tissue and then the skin will be closed.

Device: Silicone prosthesis
Silicone prosthesis

Active Comparator: Group control: Usual surgical technique

Breast cancer conservative surgery will be performed according to the usual surgical technique, that is, removing the tumor and covering the defect by mobilizing the breast tissue and then closing the skin.

Procedure: Usual practice
Usual surgery

Outcome Measures

Primary Outcome Measures

  1. Aesthetic result [4 weeks]

    Aesthetic result of the new technique by applying a visual analog scale for measuring patient satisfaction. Scale ranges: minimum score: 0 (no satisfaction - worse outcome), maximum score: 10 (total satisfaction - better outcome)

Secondary Outcome Measures

  1. Surgical complications [4 weeks]

    Incidence of surgical complications.
