BARRERA E, ALEJANDRO. Curative extended resections for locally advanced colon cancer. Rev Chil Cir [online]. 2007, vol.59, n.1, pp.46-54. ISSN 0718-4026.  http://dx.doi.org/10.4067/S0718-40262007000100009.

Background: Occasionally, colon tumors can involve neighboring organs and during surgery, an extended en bloc resection must be performed. Aim: To report the experience with extended resection of locally advanced colon tumors. Material and methods: Retrospective revision of medical records of patients subjected to an extended curative resection for locally advanced colon cancer. Results: In a ten years period, 187 patients with colon cancer were operated. Excluding patients subjected to palliative resections and with distant metastasis, in 25 (aged 28 to 82 years, 15 females), an involved abdominal structure had to be excised with a curative intention. Left and right colon were excised in 15 and 10 patients, respectively. Abdominal CAT scan diagnosed some type of organ infiltration in 63% of these patients and was concordant with operative findings in 50%. Abdominal ultrasound disclosed the infiltration only in 25% of patients in whom it was performed. The most commonly involved structures were abdominal wall and small bowel. Pathological examination showed malignant infiltration in 12 patients (48%). Twelve patients had a stage II tumor and 13 an stage III tumor. Mean hospital stay was 12 days. Five patients had postoperative complications and two required a new operation. One patient died. In a follow up ranging from 3 to 69 months, survival was 57% for stage III tumors and 100 % for stage II tumors. One surviving patient has a disseminated cancer and the rest are tumor free. Survival among deceased patients, ranged from 5 to 19 months. Conclusions: Extended resection of locally advanced colon cancer is a therapeutic alterative with a low mortality and complications and with a good long term survival
