Day late and dollar short! Delayed recurrence of recto-sigmoid cancer involving sacrum and long term surveillance

Patients with colorectal cancer will develop recurrence of the disease with greater than 90% having it in the first 5 years following surgery. If detected early, may be amenable to potentially curative surgical resection. This provides the rationale for a follow-up strategy in patients with resected colorectal cancer. We report a case of a 68-year-old female who had a loco regional recurrence after 13 years of primary surgery involving the middle part of sacrum, raising the question regarding the long term surveillance.
