Prognosis of colorectal cancer?

[TIMIR]

A 72-year-old woman with metastatic colorectal cancer presented with a 2-month history of bloating and abdominal discomfort. Her last colonoscopy was about 2 years ago and was negative, and she also had some unintentional weight loss. With regard to her past medical history, it’s significant only because of a hysterectomy done about 12 years ago and high blood pressure, which is controlled with lisinopril. During the clinic work-up, the patient was found to be anemic with an elevated CEA [carcinoembryonic antigen] of 6 ng/mL. The colonoscopy revealed a 9-cm mass in the ascending colon; biopsy of this showed a poorly differentiated adenocarcinoma. The molecular profiling showed a microsatellite stable tumor. CT scan showed widespread lesions spread across the liver. The patient was diagnosed with stage IV colorectal cancer. What is the prognosis of this disease?

@timir Survival rates can give you an idea of what percentage of people with the same type and stage of cancer are still alive a certain amount of time (usually 5 years) after they were diagnosed. They can’t tell you how long you will live, but they may help give you a better understanding of how likely it is that your treatment will be successful. A relative survival rate compares people with the same type and stage of cancer to people in the overall population. For example, if the 5-year relative survival rate for a specific stage of colon or rectal cancer is 80%, it means that people who have that cancer are, on average, about 80% as likely as people who don’t have that cancer to live for at least 5 years after being diagnosed.
