Clinical Trial Summary

Tissue Expander/Implant Reconstruction: The purpose of this study is to determine how and when nerve sensation to the breast skin returns after mastectomy.

Autologous Tissue Reconstruction: The purpose of this study is to determine whether the tissue being used to reconstruct your breast can provide sensation by using your own nerves. Typically all sensation is lost immediately after this type of surgery and returns to varying degrees. We are hoping to demonstrate that by connecting the two nerves (one from abdomen and one from the chest wall) together, we can attain meaningful sensation in the transferred tissues thereby improving your quality of life following surgery.


Description:

To determine the timing and distribution of sensation recovery of breast after mastectomy and breast reconstruction, both with autologous and implant-based reconstruction. Also, to determine the role of innervated free tissue transfer in breast reconstruction.

Specific Aims

1. Determine the timing and degree of return of breast in women who underwent mastectomy with autologous tissue or with implant based reconstruction.

2. Determine sensation following neurotized free flap reconstruction

3. Determine whether neurotization has an impact on quality of life measures post operatively

Study Design Patients will be enrolled prospectively in this data collection study in which they will receive the standard of care for breast cancer resection and oncologically safe and accepted means of breast reconstruction with tissue expander and/or prosthetic implants. Patients will receive additional, non-invasive sensory testing, performed at standard follow up intervals in clinic by their reconstructive team. All patients participating in the study will be consented for enrollment at the pre-operative visit by either the surgeon or physician assistant. As this is a prospective study, all women fitting inclusion criteria over a 6-month minimal, but projected goal 12-month period will be included.

Autologous Breast Reconstruction
Patients undergo unilateral or bilateral reconstruction of breasts after nipple sparing mastectomy. Breasts are reconstructed with the patient's own tissue
Neurotization
Nerve will be reconstructed during autologous breast tissue reconstruction

Outcome

Type Measure Description Time frame Safety issue
Primary Composite measure of sensation Differences of at least 20% comparing control to experimental breasts would be clinically meaningful. Composite measure will be calculated by combining the follow binomial factors: detection of temperature difference (feeling hot and cold), detection of sharp versus dull pressure, detection of vibration, discerning point pressure Up to 24 months after surgery
Secondary Quality of Life as measured by a 19-question survey regarding sensation and appearance of breast. A total of 19 Likert scale questions will be given to participants in the pre- and post-Surgical Sensation Questionnaire regarding sensation and appearance of breast before and after reconstruction. Up to 24 months after surgery
