Quantitative Assessment of Autologous Fat Transfer

Summary

This is a single-arm, prospective pilot study that will objectively assess outcomes in patients electively undergoing Autologous Fat Transfer (AFT) for breast or chest wall reconstruction. Patients planning to undergo autologous fat transfer for breast or chest wall reconstruction will be enrolled prospectively. Participants will undergo standard photographs (2-D imaging) of their chest wall and torso, including the breasts, and complete a validated questionnaire (BREAST-QTM) to evaluate patient satisfaction, and quality of life, all standard of care. The 3D photographs, Magnetic resonance imaging (MRI), and Ultrasound (US) are routinely used in practice but will be performed for research purposes in this study. All imaging procedures and questionnaires will be obtained at baseline and follow-up visits 3-6.

Interventions

• Procedure
  2-Dimensional (2-D) Photographs (Visit 1/ Follow up Visit 3-6)

  The study participant will be requested to stand upright with hands comfortably behind their back and turn 45 degrees and 90 degrees in either direction for standard anteroposterior (AP), oblique and lateral photos. Standardized photographic poses will be utilized so that only the participant's neck and torso will be visible and all jewelry on the neck and arms will be removed to eliminate potential identifiers. The photographs will be acquired using a commercially available camera or study iPad device.

• Procedure
  3-Dimensional (3-D) Photographs (Visit 1- 6)

  3-Dimensional surface scans of the participant's torso will be acquired using a commercially available handheld camera scanning device that offers texture, geometry, and color acquisition from any complex surface using white light technology, which is safe for exposure to skin and eyes. Prior to imaging, a pattern of lines and dots will be marked on the patient's breasts using a washable marker. The study participant will be requested to sit upright on the exam room table with hands comfortably behind their back while the research staff member moves around their torso with the handheld scanner. The exam room table will then be reclined to a lay-flat position such that the patient is laying supine, and breast imaging will be repeated. Standardized photographic poses will be utilized so that only the participant's neck and torso will be visible and all jewelry on the neck and arms will be removed to eliminate potential identifiers.

• Procedure
  Ultrasound Soft Tissue Assessment (Visit 1/ Follow up Visit 4-6)

  The images will be acquired using a commercially available handheld ultrasound scanning device. The study participant will be requested to sit upright on the exam room table with hands comfortably behind their back while the research staff member obtains images of the specific area of the breast of chest wall to be grafted (V1) and that which was grafted (V4-6). Images usually take 5-10 minutes to acquire depending on the number of areas grafted.
