Colon and Rectal Cancer Follow-Up Care

WHY SHOULD THERE BE A POSTOPERATIVE FOLLOW-UP PROGRAM?

Surgery is the most effective treatment for colorectal cancer. Even when all visible cancer has been removed, it is possible for cancer cells to be present in other areas of the body. These cancer deposits, when very small, are undetectable at the time of surgery, but they can begin to grow at a later time. The chance of recurrence depends on the characteristics of the original cancer and the effectiveness of chemotherapy, if needed, or other follow up treatment. Patients with recurrent cancers - if diagnosed early - may benefit, or be cured, by further surgery or other treatment.

Another good reason for postoperative follow up is to look for new colon or rectal polyps. Approximately one in five patients who has had colon cancer will develop a new polyp at a later time in life. It is important to detect and remove these polyps before they become cancerous.

HOW LONG WILL MY FOLLOW-UP PROGRAM LAST?

Most recurrent cancers are detected within the first two years after surgery. Therefore, follow up is most frequent during this period of time. After five years, nearly all cancers that are going to recur will have done so. Follow up after five years is primarily to detect new polyps, and can, therefore, be less frequent but advisable for life.

WHAT MIGHT I EXPECT AT MY FOLLOW-UP VISIT?

Your doctor will examine you approximately every two or three months for the first two years, and discuss your progress. A CEA blood test can be done, as a method of trying to detect recurrence of cancer. Because this test is not totally reliable, other follow up examinations may be advised. These examinations may include flexible sigmoidoscopy (an examination of the rectum and lower colon with a flexible, lighted instrument), colonoscopy (examination of the entire colon with a long flexible instrument), chest x-rays, and sometimes CT scans or ultrasound tests.

WHAT ABOUT MY FAMILY?

Close relatives of patients with colon and rectal cancer (parents, brothers, sisters, children) are at increased risk for the disease. Because of this risk, periodic colonoscopy is advised to detect small polyps. Prompt detection and removal of polyps reduces the risk of developing cancer. Your colon and rectal surgeon can further advise you and your family members on colonoscopy. Other factors which increase the risk of developing polyps or cancer include cancer occurring at an early age, and a personal history of breast or female genital cancer. 

WHAT IS A COLON AND RECTAL SURGEON?

Colon and rectal surgeons are experts in the surgical and non-surgical treatment of diseases of the colon, rectum, and anus. They have completed advanced surgical training in the treatment of these diseases as well as full general surgical training. Board-certified colon and rectal surgeons complete residencies in general surgery and colon and rectal surgery, and pass intensive examinations conducted by the American Board of Surgery and the American Board of Colon and Rectal Surgery. They are well-versed in the treatment of both benign and malignant diseases of the colon, rectum and anus and are able to perform routine screening examinations and surgically treat conditions if indicated to do so.
