Clinical Trial Summary

This study will compare the cosmetic scar result from the use of scalpel, electrocautery, and pulsed electron avalanche knife (PEAK) PlasmaBlade (PPB) for the initial skin incision for total mastectomy procedures without immediate breast reconstruction. It is hypothesized that there will be no significant difference in mastectomy scar cosmesis. The purpose and objectives of this study are: 1. To evaluate and compare the cosmetic scar result from the use of scalpel, standard electrocautery, or PEAK PlasmaBlade for initial incision for total mastectomy procedures without immediate breast reconstruction. 2. To inform future equipment choices for breast surgery including potential elimination of scalpels and their attendant risks.

Description:

Scalpel, electrocautery, and PEAK PlasmaBlade (PPB) have all been shown to be safe techniques for surgical incision, but no study has proven the superiority for cosmesis for PPB incision when compared to conventional electrocautery or scalpel. The investigators propose a double blind prospective randomized controlled study of consecutive patients scheduled for total mastectomy +/- axilla staging without immediate breast reconstruction to evaluate the cosmetic scar result from the use of scalpel, standard electrocautery or PEAK PlasmaBlade. Scar cosmesis will be evaluated postoperatively at two-to-four weeks, six months, and twelve months by two independent observers blinded to the equipment used, and patient reported outcomes will be reported using the validated SCAR-Q questionnaire.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Scar cosmesis (SCAR scale)	Mastectomy site scar cosmesis will be evaluated 2-4 weeks post-operatively by two independent observers blinded to the equipment used for the surgery using photo evaluation with the Scar Cosmesis Assessment and Rating (SCAR) scale. The SCAR scale yields scores ranging from a minimum score of 0 (best possible scar) to a maximum score of 15 (worst possible scar).	2-4 weeks post-operatively
Primary	Scar cosmesis (Vancouver Scar Scale)	Mastectomy site scar cosmesis will be evaluated 2-4 weeks post-operatively by the treating surgeon using the Vancouver Scar Scale for physical examination. The Vancouver Scar Scale yields scores ranging from 0 (best) to 13 (worst).	2-4 weeks post-operatively
Primary	Scar cosmesis (SCAR-Q)	Patient reported outcomes will be reported 2-4 weeks post-operatively using the SCAR-Q scale, a comprehensive scar appearance scale with independently functioning domains for scar appearance, scar symptoms and psychosocial impact, which each yield transformed scores ranging from 0 (worst) to 100 (best).	2-4 weeks post-operatively
Primary	Scar cosmesis (SCAR scale)	Mastectomy site scar cosmesis will be evaluated 6 months post-operatively by two independent observers blinded to the equipment used for the surgery using photo evaluation with the Scar Cosmesis Assessment and Rating (SCAR) scale. The SCAR scale yields scores ranging from a minimum score of 0 (best possible scar) to a maximum score of 15 (worst possible scar).	6 months post-operatively
Primary	Scar cosmesis (Vancouver Scar Scale)	Mastectomy site scar cosmesis will be evaluated 6 months post-operatively by the treating surgeon using the Vancouver Scar Scale for physical examination. The Vancouver Scar Scale yields scores ranging from 0 (best) to 13 (worst).	6 months post-operatively
Primary	Scar cosmesis (SCAR-Q)	Patient reported outcomes will be reported 6 months post-operatively using the SCAR-Q scale, a comprehensive scar appearance scale with independently functioning domains for scar appearance, scar symptoms and psychosocial impact, which each yield transformed scores ranging from 0 (worst) to 100 (best).	6 months post-operatively
Primary	Scar cosmesis (SCAR scale)	Mastectomy site scar cosmesis will be evaluated 12 months post-operatively by two independent observers blinded to the equipment used for the surgery using photo evaluation with the Scar Cosmesis Assessment and Rating (SCAR) scale. The SCAR scale yields scores ranging from a minimum score of 0 (best possible scar) to a maximum score of 15 (worst possible scar).	12 months post-operatively
Primary	Scar cosmesis (Vancouver Scar Scale)	Mastectomy site scar cosmesis will be evaluated 12 months post-operatively by the treating surgeon using the Vancouver Scar Scale for physical examination. The Vancouver Scar Scale yields scores ranging from 0 (best) to 13 (worst).	12 months post-operatively
Primary	Scar cosmesis (SCAR-Q)	Patient reported outcomes will be reported 12 months post-operatively using the SCAR-Q scale, a comprehensive scar appearance scale with independently functioning domains for scar appearance, scar symptoms and psychosocial impact, which each yield transformed scores ranging from 0 (worst) to 100 (best).	12 months post-operatively
