What are the chances of recurrence for a patient with the following
history.

In July 2000 she had surgery to remove a tumour in the small intestine.
It was a Stage III adenocarcinoma and had spread to regional lymph
nodes which were also removed. No adjuvant chemo after surgery. 5.5
years later she seems fit and healthy and there has been no sign of
recurrence. Followup consists of regular CT and CEA tests. She still
worries a lot about recurrence even after having 5 good years.

Thanks for any information.
