Bezpečnost a proveditelnost robotické SP bradavky šetřící mastektomie
Bezpečnost a proveditelnost robotické jednoportové (SP) bradavky šetřící mastektomie: Pilotní zkouška s jednou rukou v jedné instituci
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.

Detailní popis
rNSM using the multi-port robotic platform followed by standard of care open breast reconstruction has been done successfully at multiple institutions worldwide with comparable, if not superior outcomes to an open surgical approach. This study explores this procedure with the Da Vinci SP robot with pre-pectoral reconstruction with acellular dermal matrix. The patients will be evaluated per standard of care post-operative visits at 2 weeks, 1 month, and every 6 months for five years post operatively for subjective patient satisfaction and objectively for post-operative nipple sensation. The patients will be monitored longitudinally for oncologic outcomes including the presence of a new breast cancer and/or breast cancer recurrence. Patients will be monitored for any complications related to rNSM and the use of ADM in expander and implant-based breast reconstruction.
Investigational Device:
The da Vinci SP Surgical System, Model SP1098 is a software-controlled, electro- mechanical system designed for surgeons to perform single port minimally invasive surgery. The Model SP1098 Surgical System consists of a Surgeon Console, a Patient Cart, and a Vision Cart, and is used with a Camera Instrument, EndoWrist SP Instruments, and Accessories.
Indications for Use:
The da Vinci SP Surgical System, Model SP1098 is cleared for use in urologic surgical procedures that are appropriate for a single-port approach and transoral otolaryngology procedures restricted to T1 and T2 tumors. This investigational study will evaluate device usage in nipple sparing mastectomy (NSM) procedures.

Incidence of perioperative complications
Časové okno: 30 days following surgery

Perioperative complications will be described using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTACAE) v. 4.03 criteria. Complications will refer to any medical occurrence directly attributed to the surgical procedure during and within the first 30 days following use of the SP robotic platform and ADM. Grade 3, 4, or 5 complication or adverse event will constitute an event. Perioperative complication rates will be compared to historical complication rates. |

Patient satisfaction as measured by BREAST-Q reconstruction tool
Časové okno: Baseline, postoperatively at 2 weeks, every 6 months for 5 years
|
Patient satisfaction is measured by BREAST-Q reconstruction tool at baseline, postoperatively at 2 weeks, and every 6 months for 5 years. BREAST-Q reconstruction module and Breast implant illness survey for patients. Questions about self-confidence, comfort, acceptance of new appearance, feeling of implants, breast pain. The score represents questionnaires about different domains and each question has four possible dimensions. The values of these dimensions varies from 1 (minimum score- worst outcome) to 4 or 5 (maximum score- best outcome) (Likert Scale) depending on part of the questionnaire . |

Patient satisfaction as measured by BREAST-Q sensation tool
Časové okno: Baseline, postoperatively at 2 weeks, every 6 months for 5 years
|
Patient satisfaction is measured by BREAST-Q sensation tool at baseline, postoperatively at 2 weeks, and every 6 months for 5 years and it is another tool to help quantify breast sensation both pre-operatively and post-operatively. The Breast-Q is comprised of 2 domains - i) Satisfaction domains and ii) Well-being domains, which are further divided into sub-domains. We will be using 3 satisfaction sub-domains: i) Satisfaction with breasts ii) Satisfaction with Nipple iii) Satisfaction with outcome and 3 well-being sub-domains: i) Psychosocial well-being ii) Sexual well-being and iii) Physical well-being. The values range from 1 (minimum score- worst outcome) to 4 or 5 (maximum score- best outcome) (Likert Scale) depending on part of the questionnaire. |
