Long-term locoregional recurrences after curative surgery for colon cancer : [Recidive locoregionali e a distanza successive a trattamento chirurgico curativo del cancro del colon]

In this study, we report all patients with colon cancer who under- went laparotomic surgical treatment from 1998 to 2002. The total number of patients was 115 with average age of 65.2 years; male to female ratio was 1.61. As regards to the variations due to preoperative staging and tumor localization, our patients underwent: 34 right hemicolectomy, 80 left hemicolectomy, 1 transverse resection. According to the stage of tumor, an adju- vant chemotherapeutic treatment was associated to surgery. The aim of this study was to investigate the recurrence patterns in patients with curatively resected colon cancer followed-up for 5 years. We considered as locoregional recurrences those which developed in the same abdominal region of the primary tumor; the most common sites of distant metastases were liver and lung. Our first results show that both locoregional recur- rences and distant metastases rates depend mostly on the exten- sion of tumor (T), nodal involvement (N) and grading (G) of the primary tumor.
