Abstract

Clinical Advantage of Image-Guided Navigation for Locally Advanced Primary and Recurrent Rectal Cancer

Highlights

Patients with such tumors certainly constitute the most challenging group, given that microscopic circumferential resection margin (CRM) tumor involvement has an association with increased rates of local recurrence and decreased survival.[6]
In their study, the authors created 3-dimensional models based on preoperative computed tomography and magnetic resonance imaging along with an intraoperative tracking system linked to the 3-dimensional model to guide the surgical procedure
The historical cohort of the study included 101 patients in whom a primary resection had been undertaken and 41 patients who had undergone a resection for a recurrent rectal cancer

Summary

Introduction

Patients with such tumors certainly constitute the most challenging group, given that microscopic CRM tumor involvement has an association with increased rates of local recurrence and decreased survival.[6]. Kok and colleagues[8] are to be commended for trying to improve on these results by evaluating the use of navigation during resection. In their study, the authors created 3-dimensional models based on preoperative computed tomography and magnetic resonance imaging along with an intraoperative tracking system linked to the 3-dimensional model to guide the surgical procedure.
