Radiographically guided shave margins may reduce lumpectomy re-excision rates

Abstract

Minimizing margin re-excision optimizes patient care by providing appropriate oncologic resection and reducing costs. This study aims to assess margin positivity rate in two groups: shave margin based on gross specimen (control group, CG) vs shave margin based on intraoperative imaging (radiographic group, RG). A total of 182 patients who underwent lumpectomy for stage O-III breast cancer at a single institution from January 2013 to January 2014 were evaluated. There was statistically significant decrease in margin re-excision rate with intraoperative mammography but not with ultrasound. Surgeons are ideally equipped to use intraoperative imaging to guide margin excision, thus, improving care and reducing costs.

Útilidad de la ecografía intraoperatoria en la exéresis de las lesiones no palpables de la mama. Experiencia y revisión de conjunto

“…Otra de las ventajas, y la más importante, es que permite comprobar intraoperatoriamente los márgenes de la lesión y, si es necesario, realizar una ampliación de esos márgenes en ese momento, disminuyendo así el número de reintervenciones por márgenes afectos [36][37][38] . Si, además, asociamos la EIO al estudio de los márgenes ex vivo intraoperatoriamente, tal y como lo realizamos en nuestro hospital, el porcentaje de reintervenciones por márgenes afectos mejora significativamente [39][40] . Ésto conlleva un mejor resultado estético incrementando la satisfacción de los pacientes y su calidad de vida.…”

The application of intraoperative specimen mammography for margin status assessment in breast‐conserving surgery: A single‐center retrospective study

“…SR is a fast, convenient, and cost‐effective method. Several studies demonstrated that intraoperative mammography reduced positive margins 3,4 . No significant difference was found between SR and frozen sectioning 5 .…”
