Outcome Measures

Primary Outcomes (3)

  • Conversion rate

    Conversion is defined as conversion of da Vinci Xi robotic-assisted surgery to open surgery

    Assessed during procedure

  • Safety: Adverse event rates

    Incidence of intraoperative and post-operative procedure and device-related adverse events compared to open NSM

    Up to 42 days post-operatively

  • Safety: positive surgical margin rates

    Incidence of positive surgical margins compared to open NSM

    Up to 42 days post-operatively

Secondary Outcomes (6)

  • Oncological Outcomes (for cancer recurrence)

    Up to 5 years

  • Oncological Outcomes (for disease-free survival)

    Up to 5 years

  • Oncological Outcomes (for overall survival)

    Up to 5 years

  • Patient-Report Outcomes (BREAST-Q)

    Up to 5 years

  • Patient-Report Outcomes (NAC Questionnaire)

    Up to 5 years

  • +1 more secondary outcomes
