Why do you think the loss of sensation in the breast after mastectomy hasn’t gotten that much attention until now?
Sensation is not something we talk about enough. Breasts are an intimate part of the body. Women have been hesitant to talk about it too much, or to talk about it in a public setting. It’s hard to talk about breast surgery without pointing to your breasts or calling attention to them, and this isn’t something a lot of women are comfortable with. I want to make this a comfortable and acceptable conversation for women to share and not be embarrassed. I also think there is a little bit of guilt for some women too. They feel they should be grateful that they no longer have cancer. I want women to feel they have the opportunity to choose whether reconstruction is the right option for their life and to have the possibility to potentially return to feeling normal. A lot of women never tell their surgeon that they are unhappy with the loss of sensation. Some surgeons aren’t aware that the loss of feeling is a significant issue for their patients and they are not aware that breast nerve restoration is a possibility. So, the loss of sensation is something that women talk about only in the privacy of their home, or with family and friends.
How was ReSensation developed?
For every challenge, there are medical pioneers who recognize a patient problem and work tirelessly to solve it. Breast sensation following breast reconstruction is no different. AxoGen worked with a group of leading experts in breast reconstruction – pioneering surgeons who believed there was a real opportunity to make a fundamental shift in what a woman should potentially expect when she has autologous breast reconstruction surgery. We combined their surgical expertise with our deep knowledge of nerves and nerve regeneration to develop the ReSensation technique.
Reconstruction has traditionally focused on appearance. How does the AxoGen procedure change that paradigm?
Breast reconstruction has come a long way. The outcomes in terms of how breasts look are very reliable. In many women, it’s hard to tell they had surgery at all. It’s hard to see the scars. Surgeons do such a beautiful job in giving the women the look and shape of a breast. But the whole concept of sensation has been downplayed. Breast reconstruction up until now has been more about aesthetics, which is outward-focused and involves the way other people see you. ReSensation is inward-focused. It is about the woman. This is a major shift that offers women the possibility of getting the outcomes they desire. We believe that regaining sensation is going to have a major impact on women’s quality of life.
How much sensation may be returned?
We’re working with some major universities on gathering that data. We currently have over 1,400 nerve repair procedures enrolled in our RANGER® registry to measure outcomes for a wide variety of applications for peripheral nerve repair. In addition, other published data that utilizes our allograft nerve tissue
for supporting return of sensation tells us we can get meaningful outcomes in 86% to 92% of the nerves that are repaired. Sensation-NOW™ (Neurotization Outcomes for Women) is an arm of the RANGER registry focused on measuring outcomes for breast neurotization specifically. We will measure the psychological impact, the quality of life impact and the physical impact of breast neurotization. After mastectomy, women can also be at risk of pain in the area where the nerves were damaged. We are also evaluating if breast nerve repair can help with pain. The academic centers are very supportive about gathering this information and building a repository of data that aims to change the standard of care. That’s how you change medicine. You provide surgeons good evidence to make better decisions. And I think Sensation-NOW will do that.
If a woman is interested in the possibility of restoring sensation after a mastectomy, what questions should she ask her surgeons?
A woman has a lot of choices to make from the time she is diagnosed with cancer and decides to have a mastectomy, or from the time she decides to prophylactically have a mastectomy. She needs to decide who’s going to be the breast surgeon to manage the removal of the tissue. Then she needs to decide if she is going to have a reconstruction, what type of reconstruction, whether she wants an immediate or delayed reconstruction and who will be her plastic surgeon
to do the reconstruction. Women can choose between breast implants and an autologous reconstruction
, also known as free flap reconstruction. In free flap reconstruction, tissue is taken typically from the abdomen or another part of the body to form a breast mound. There are trade-offs between these two techniques. The pros and cons of each are something for women to carefully consider. Breast neurotization with ReSensation can only be done with autologous reconstruction. Reconstruction surgery with ReSensation can be done right after a mastectomy or after some time has passed. The technique uses allograft nerve tissue to connect the nerves of the autologous tissue with the nerves in the chest. Over time, the nerve fibers regenerate across the allograft, then continue to grow to the skin. If a woman is interested in exploring the possibility of restoring sensation, she needs to look for surgeons who are performing the procedure. She needs to let her surgeon know that breast neurotization and a return of sensation is important to her. There are approximately 20 to 25 hospitals in the United States that will specialize in breast neurotization and the ReSensation technique. In choosing who we work with, we wanted to make sure that there was reasonable access for all women across geographic areas. We also wanted to be sure we were working with surgeons who are passionate about this new advancement in breast reconstruction.
What makes you the most proud about the work the team at AxoGen is doing?
I am enormously proud of the team at AxoGen. They wake up every day and think about what they can do to make patients’ lives better. And they stay unwaveringly committed to that. It’s hard work, but they do it in partnership with these wonderful pioneering surgeons who are equally passionate about it, and I think each group feeds off the other to make new options in care possible. We all see the potential to dramatically change breast reconstruction surgery, and that carries us through the effort.
Should all women seek ReSensation after mastectomy?
It’s a very personal choice. Some women don’t want reconstruction. They might wear a prosthetic or they might just go without breasts. That’s what’s right for them. Some women will want to go through reconstruction and explore options for restoring sensation. I think each woman has to find the right thing for her life to give her the greatest happiness and outcomes.
