Recurrence of the disease, obviously, represents the major problem in patients who undergo "curative" resection for rectal cancer, with published rate ranging from 3 to 50%. Most relapses occur within the first two years of follow-up [1-4].
Depending on the site of the recurrence, it can be local or distant. It also can be solitary or diffuse. In terms of potential surgical cure, the best results are achieved with solitary, localised metastases.
The most common sites of the solitary metastases are pelvis, liver and lung, with a fairly even distribution among these three sites . Other sites of localised metastases can be peritoneum, lymph nodes, brain, bone, abdominal wall, ureter and kidney. These sites are less common, but not as amenable to resection.
