The cumulative recurrence rate in colon cancer was 100% at 4 years . In rectal cancer, it was 89% at 5 years, 98% at 7 years and 100% at 10 years. The interval until recurrence was longer in rectal cancer (26.0 +/- 24.2 months) than in colon cancer (17.1 +/- 11.0 months) (p = 0.03).
For most people, colorectal cancer doesn't come back, or “recur.” But in about 35% to 40% of people who get surgery with or without chemotherapy, the cancer may come back within 3 to 5 years of treatment . If this happens, it could be in the colon or rectum, or in another part of the body, such as the liver and lungs.
Once a patient has been successfully treated for colon cancer, the follow up appointments may be every 3 months. This is because 60 – 80% of colon cancer recurrence is within 2 years of the original diagnosis/malignancy .
The liver was the most common site of early recurrence (40.5%), whereas late recurrence was more common locally (28.1%), or in the lung (32.8%).
But with survival comes a new risk — that of recurrence. Colorectal cancer recurrence within five years after treatment ends is in the range of 7 to 42 percent , depending on the stage of the cancer. The risk of cancer recurrence is understandably a common source of worry and anxiety for many who have had this cance
“Your risk of recurrent colon cancer changes with time.”
After a first colon cancer, 80% of recurrences happen in the first two to three years . “We check the blood every three to six months so we can check a tumor marker, and we'll do an annual CT scan and periodic colonoscopie
People who have had colon cancer can get any type of second cancer , but they have an increased risk of: A second colon cancer (This is different from the first cancer coming back
Cancer of the colon is a highly treatable and often curable disease when localized to the bowel . Surgery is the primary form of treatment and results in cure in approximately 50% of the patients. Recurrence following surgery is a major problem and is often the ultimate cause of deat
