[Extended lymphadenectomy in carcinoma of the right colon]

The Authors report on a retrospective study concerning 49 patients treated for a modified Dukes' stage B, C or D right colon cancer. A potentially curative right hemicolectomy with extended lymphadenectomy was performed. Locally advanced disease was treated by "en bloc" resection. Two (4.1%) patients died after surgery, in other 2 (4.1%) cases major postoperative complications were registered. Microscopic examination of the surgical specimens showed lymph node metastases in 44.9% of the cases: in this subgroup a metastatic involvement of the main (III level) nodal groups was detected in 22.7% of the patients. The Authors conclude that extended lymph node dissection does not increase postoperative complications and may play a role in the treatment of right colon cancer. A not negligible group of patients may be understaged or receive inadequate surgical treatment when submitted to traditional right colectomy.
