简要总结
This is a single-site, randomized, double-blinded trial to assess whether neurotization following autologous breast reconstruction in patients with breast cancer increases quality of life and sensation in the breast compared to breast reconstruction without neurotization. 50 participants will be enrolled and can expect to be on study for up to 18 months after reconstruction surgery.
详细描述
In 2019, nearly one third of cancers diagnosed in the United States were breast cancers. Per the Plastic Surgery procedural statistics from the American Society of Plastic Surgery database, that same year approximately 107,000 patients decided to pursue either alloplastic (ex. Tissue expander or implant based) or autologous (ex. Transverse Rectus Abdominis Muscle (TRAM), Deep Inferior Epigastric Perforator (DIEP) flaps) breast reconstruction, an increase of 5% from 2018. Over the past few decades, as surgical techniques have continued to improve, postoperative concerns have transitioned towards the patient's aesthetic outcome and satisfaction. While the appropriate size, shape, and symmetry of the breast are crucial goals to achieve, another issue facing patients is that without sensation the reconstructed breast does not feel like their own. In most patients there is diminished, if not absent, sensation in the reconstructed breast. The lack of sensation can not only put patients at risk of injury, but also can impact their lives sexually and socially.
The goal of this randomized, double-blinded study is to prospectively evaluate the impact of neurotization on breast-specific quality of life in patients who have undergone autologous reconstruction. Secondary objectives are to also look at additional health-related quality of life outcomes using validated surveys (e.g. PROMIS and NIH Toolbox). These NIH-funded surveys will be analyzed to assess factors important to surgical impact on physical function, mental function, social function, pain, and sexual function. Finally, investigators will objectively measure differences in sensation. Investigators hypothesize that breast neurotization will improve both breast- and health-related patient quality of life outcomes as well as objective sensation. The duration of this study is expected to be approximately 48 months in order to recruit an appropriate number of patients and have adequate postoperative follow up.

结局指标
主要结局
Breast-Q® score in participants who have undergone autologous reconstruction with TRAM/DIEP flaps with and without neurotization
时间窗: approximately 12 months after reconstruction
Self-reported, breast-specific health-related QoL(Quality of life) via use of the Breast-Q® in participant with breast cancer who have undergone autologous reconstruction with TRAM/DIEP flaps with and without neurotization. This score represents questionnaires about different domains and each question has four possible dimensions. The values of these dimensions varies from 1 to 4 (Likert Scale). The sum of each domain raw score scale will be plotted in the Breast Q Conversion Table to convert the summed domain score to a Equivalent Rasch Transformed Score with values ranging from 0 (worst) to 100 (best).
次要结局
- Change in PROMIS Psychosocial Illness Impact-Positive SF8a score in participants who have undergone autologous reconstruction with TRAM/DIEP flaps with and without neurotization(Baseline(pre-operative), approximately 1-3 weeks, 6 weeks, 3 months, 6 months, 12 months, and 18 months after the reconstruction)
- Change in mean monofilament value in participants who have undergone autologous reconstruction with TRAM/DIEP flaps with and without neurotization(Baseline(pre-operative), approximately 1-3 weeks, 6 weeks, 3 months, 6 months, 12 months, and 18 months after the reconstruction)
- Change in number of touch sensitive breast locations in participants who have undergone autologous reconstruction with TRAM/DIEP flaps with and without neurotization(Baseline(pre-operative), approximately 1-3 weeks, 6 weeks, 3 months, 6 months, 12 months, and 18 months after the reconstruction)
- Change in Breast-Q® score in participants who have undergone autologous reconstruction with TRAM/DIEP flaps with and without neurotization(Baseline(pre-operative), approximately 1-3 weeks, 6 weeks, 3 months, 6 months, 12 months, and 18 months after the reconstruction)
- Change in Ability to Participate in Social Roles and Activities assessed by the PROMIS SF8a score in participants who have undergone autologous reconstruction with TRAM/DIEP flaps with and without neurotization(Baseline(pre-operative), approximately 1-3 weeks, 6 weeks, 3 months, 6 months, 12 months, and 18 months after the reconstruction)
- Change in PROMIS Psychosocial Illness Impact-Negative SF8a score in participants who have undergone autologous reconstruction with TRAM/DIEP flaps with and without neurotization(Baseline(pre-operative), approximately 1-3 weeks, 6 weeks, 3 months, 6 months, 12 months, and 18 months after the reconstruction)
- Change in Pain Interference assessed by PROMIS SF8a score in participants who have undergone autologous reconstruction with TRAM/DIEP flaps with and without neurotization(Baseline(pre-operative), approximately 1-3 weeks, 6 weeks, 3 months, 6 months, 12 months, and 18 months after the reconstruction)
- Change in Pressure-Specified Sensory Device (PSSD) score in participants who have undergone autologous reconstruction with TRAM/DIEP flaps with and without neurotization(Baseline(pre-operative), approximately 1-3 weeks, 6 weeks, 3 months, 6 months, 12 months, and 18 months after the reconstruction)
