18 Clinical Trials for Various Conditions
Patients with a germline pathogenic variant (GPV) in high-penetrance breast cancer susceptibility genes who are considering risk reducing mastectomy (RRM) often strongly desire to keep their nipple areola complex but inquire as to whether it is safe to do so. Relative to traditional or skin sparing mastectomy (SSM) techniques, nipple sparing mastectomy (NSM) is associated with improved psychosocial and sexual well-being and is significantly better for body image and reducing feelings of disfigurement. Despite this, guidelines have yet to endorse the use of NSM over other RRM techniques, stating that more data and longer follow-up are needed to confirm it as a safe and effective strategy in GPV carriers. As NSM was not routinely adopted in high-risk patient populations undergoing RRM before 2010, there has been little data to inform the long-term oncologic safety of NSM. Well-designed studies have reported low to negligible rates of subsequent breast cancer in BRCA1/2 carriers following NSM, but have been limited by short median follow-up of less than 3 years. The current study is designed to confirm, with longer follow-up, prior findings on the oncologic safety of NSM in unaffected BRCA1/2 carriers. The investigators will also expand data to other high-penetrance GPV carriers, including PALB2, CDH1, PTEN, and TP53, for whom there is little-to-no data on outcomes following RRM.
This phase II trial tests the willingness of patients undergoing nipple sparing mastectomy (NSM) to enroll in a randomized study of NSM with or without neurotization of the nipple areolar complex (NAC). This trial also compares patient reported outcomes, including quality of life and breast and NAC sexual functionality, for patients undergoing NSM with or without neurotization of the NAC. NSM is a standard practice option for patients undergoing preventative mastectomy, but many report dissatisfaction with decreased nipple sensation. Neurotization is a surgical technique using a nerve graft in an attempt to restore NAC sensation. Neurotization during NSM and reconstruction may restore NAC sensation and improve quality of life in breast cancer patients.
This is a single arm, single-center, prospective clinical trial designed to track the peri, post-operative and oncologic outcomes when utilizing the da-Vinci single port (SP) robotic platform to perform robotic nipple sparing mastectomy (rNSM) and immediate breast reconstruction with tissue expanders/implants and acellular dermal matrix (ADM - Alloderm), for patients with breast cancer as well as those with a high risk for breast cancer. Safety and feasibility measures will be measured as primary outcome measures. Oncological and patient satisfaction outcome measures will be measured. Our hypothesis is that SPr-NSM is equal to open NSM in terms of safety, feasibility and oncological outcomes with improved patient satisfaction as measured by nipple sensation and patient reported outcomes.
This is a prospective registry trial to determine the outcomes of single port robot-assisted nipple sparing mastectomy (SPrNSM) utilitzing the SP da Vinci surgical system.
This novel study will assess the feasibility and outcomes of same-day discharge following mastectomy with implant-based pre-pectoral reconstruction. This contrasts the current standard practice of admitting patients to the hospital as an inpatient for at least one night postoperatively. With the advent of pre-pectoral implant-based reconstructive techniques as opposed to the historical retro-pectoral breast reconstruction, patients experience significantly less post-operative pain, shorter recovery time, and improved mobility all of which support that patients lacking comorbidities are likely to meet discharge criteria the same day as surgery. Furthermore, advances in opioid sparing anesthesia and the Enhanced Recovery After Anesthesia protocol, has dramatically reduced pain scores and narcotic requirements after surgery at our institution. "Same day discharge" may reduce healthcare costs, decreases the risk of hospital-acquired infections and can increase patient satisfaction. Potential risks associated with same day discharge include readmissions, infections, limitations to pain management and other complications. The study will be conducted at MedStar System Hospitals and the population will be patients receiving pre-pectoral breast reconstruction following mastectomy that consent to the study. The project will be conducted as a prospective study where a carefully selected group of women without comorbidities undergoing mastectomy and pre-pectoral implant-based reconstruction will be offered same day discharge, educated about postoperative care preoperatively, be evaluated in the PACU and if they meet discharge criteria, will go home the same day as surgery. Those women who do not meet discharge criteria will stay overnight and be followed for outcomes, as well, as a comparison group. The primary endpoint for this study is patient satisfaction. Secondary outcomes include pain, complications including infection, hematomas, return to emergency room or urgent care, opiate equivalent use, and whether a patient would recommend same day discharge to others. Statistical analysis using means, 95% CI, frequency counts, descriptive statistics, fisher exact test and independent t-tests will evaluate differences between the same day discharge and admitted groups. Please see section 6 in the IRB protocol for more detail. We hypothesize that same day discharge provides acceptable patient satisfaction, pain control, complication rates with similar opiate equivalent use in comparison with overnight admission. Overall, we think this group will demonstrate positive outcomes on its own in these categories. We also believe that this study will demonstrate patients with same day discharge will recommend it to other women undergoing mastectomy.
This is a pilot study to determine safety, efficacy, and potential risks of robot assisted nipple sparing mastectomy (RNSM), by utilizing the daVinci surgical system.
This is retrospective, multicenter chart review is to evaluate the complication rates of prophylactic open NSM procedures through 42 days postoperatively
This trial is to investigate whether pre-pectoral Implant-Based Breast Reconstruction (IBBR) provides better Quality of Life (QoL) with respect to long-term (24 months) physical well-being (chest) compared to sub-pectoral IBBR for patients undergoing skin-sparing mastectomy or nipple-sparing mastectomy for prevention or treatment of breast cancer.
This study evaluates the safety and effectiveness of the da Vinci Surgical Systems in prophylactic Nipple Sparing Mastectomy procedures.
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.
Approximately 100 women scheduled for NSM will be consented pre-operatively to participate in the study. US will be performed after induction of general anesthesia, prior to surgery using Sonosite™ portable US, 5-12mHz transducer using doppler mode.
This study will evaluate the effect of OxyGenesys Dissolved Oxygen Dressing in wound complication rates of the nipple areolar complex after a nipple sparing mastectomy.
The purpose of this research study is to see if a participant's nipple and areola can be safely preserved by adding radiation to these areas after a nipple-sparing mastectomy and immediate breast reconstruction.
The purpose of this study is to observe the cosmetic outcomes, patient satisfaction, and complications after skin sparing mastectomy with preservation of the nipple areolar complex.
The overall objective of this proposal is to conduct a randomized-controlled study to determine whether treatment with dehydrated human amnion/chorion membrane (dHACMs) allografts can improve NAC viability in patients undergoing nipple sparing mastectomy (NSM). dHACM allografts are commercially available tissue membranes with biocompatible extracellular matrix and growth factors that have been shown to improve wound healing in patients with chronic and lower extremity wounds. To date, no study has evaluated the impact of dHACMs on NAC preservation following NSM. Investigators hypothesize that subareolar surgical implantation of dHACM allografts at time of NSM will reduce NAC necrosis and improve viability.
This study evaluates the safety and effectiveness of the da Vinci SP Surgical System compared to Open NSM in Nipple Sparing Mastectomy procedures.
The investigators hypothesize that nipple-areola skin sparing mastectomy (NASSM) performed through an inframammary incision has a superior blood supply relative to a lateral oblique incision. Moreover, by minimizing complications and optimizing aesthetic outcomes, the investigators believe it will be associated with significantly higher patient reported outcome scores. The addition of information gained by use of intraoperative laser-assisted fluorescent angiography (measured with the Spy Elite imaging device) will reduce complication rates by directing intraoperative resection of ischemic tissue and limiting the volume of immediate implant placement in instances where real time imaging would suggest compromised perfusion. These quantifiable, objective measures will justify the use of NASSM and immediate implant placement coupled with intraoperative laser-assisted fluorescent angiography in prosthetic based breast reconstruction despite longer operative times.
The goal of this study is to study nipple-areolar complex (NAC) sparing mastectomy as an alternative procedure to the standard skin-sparing mastectomy for women who have breast cancer or are at high-risk for developing breast cancer. You have been asked to take part in this study because your treating surgeon feels you are a candidate for skin-sparing mastectomy and because you want breast reconstruction after surgery. Outcomes that will be measured include how much nipple sensation can be kept after surgery; how satisfied you are with how the breast looks after surgery; complication rates; and your quality-of-life.
