The clinical outcome and prognostic factors after multi-visceral resection for advanced colon cancer

AimThe value of multi-visceral resection (MVR) for treating primary advanced colon cancer infiltrating into the neighboring organs had been debated because of the high mortality.MethodsWe reviewed 1288 patients who underwent curative resection for pT3–4 colon cancer without distant metastasis from 1994 to 2004.ResultsEighty four patients (6.5%) with colon cancer infiltrating into the neighboring organs (cT4) underwent MVR. The accuracy of the intra-operative decision for true invasion (pT4) was 35.7%. Major surgical morbidity occurred in 11 patients of the standard resection group (0.9%) and in 2 patients of the MVR group (2.3%) (p = 0.206). Most of the recurrence was distant metastasis (20 patients, 23.8%). Local recurrence was occurred in five patients (6.0%). The prognostic factors for recurrence and survival were pathologic tumor invasion (p = 0.033 and p = 0.016, respectively) and lymph node metastasis (p = 0.010 and p < 0.001, respectively).ConclusionMulti-visceral resection was a safe and curative procedure as compared with standard resection for patients with advanced colon cancer. The cause of a poor prognosis in MVR was not local recurrence but distant metastasis. Pathologic tumor invasion and lymph node metastasis were the potential prognostic factors.
