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 underwent 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 adjuvant 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 recurrences and distant metastases rates depend mostly on the extension of tumor (T), nodal involvement (N) and grading (G) of the primary tumor.
