Abstract
Purpose
The type of surgery or surgical approach for transverse colon cancer treatment largely depends on the tumor location or surgeon’s preference. However, extensive lymphadenectomy appears to improve the long-term outcomes of locally advanced colon cancers. This study was designed to compare the short- and long-term outcomes after surgery via the laparoscopic or open approach with radical D3 lymph node dissection in patients with stage II and III transverse colon cancer.
Methods
Patients were treated for stage II and III transverse colon cancer between May 2006 and December 2014. This retrospective study evaluated data collected prospectively at a tertiary teaching hospital. Radical D3 lymphadenectomy included the principal middle colic artery nodes.
Results
The study included 144 patients among whom 118 (81.9%) underwent laparoscopic surgery. Significantly more patients in the laparoscopic group underwent extended right hemicolectomy compared with the open group (90.7 vs. 65.4%, p = 0.005). The operative time was longer in the laparoscopic group (151.3 vs. 131.2 min, p = 0.021), and the open group had a greater estimated blood loss volume (160.8 vs. 289.3 ml, p = 0.011). Although the groups differed in terms of tumor size (5.8 vs 7.9 cm, p = 0.007), other pathologic outcomes did not differ. The groups did not differ regarding postoperative parameters or disease-free, overall, and cancer-specific survivals.
Conclusion
Despite differences in surgical methods and related factors, no long-term differences in outcomes were observed between laparoscopic and open approaches to radical D3 lymphadenectomy in patients with stage II and III transverse colon cancer.
