[Synchronous tumors of the colon]

Although rare, synchronous tumors of the colon represent an important clinical manifestation of cancer of the colon. The paper reports a study carried out in 437 patients with the aim of evaluating the incidence of synchronous tumours and identifying the most useful diagnostic tools for diagnosis. On the basis of the results obtained the authors conclude that the incidence of synchronous tumours of the colon ranges between 1-3% and that in comparison to other methods pancolonoscopy enables a complete diagnosis for a prophylactic approach to multiple tumours.
