When Is The Epi Procolon Test Used
The Epi proColon test is indicated for CRC screening in adults ages 50 and older who are at an average risk level. However, it isnt meant to replace standard CRC screening tests, like a colonoscopy.
The manufacturer of the test states that typical CRC screening tests should be offered and declined prior to using the Epi proColon test. Further, they note that a diagnostic colonoscopy is still necessary after a positive Epi proColon result.
Colorectal Cancer Screening Tests
A colonoscopy is one of several screening tests for colorectal cancer. Talk to your doctor about which test is right for you.
The U.S. Preventive Services Task Force recommendsexternal icon that adults age 45 to 75 be screened for colorectal cancer. The decision to be screened between ages 76 and 85 should be made on an individual basis. If you are older than 75, talk to your doctor about screening. People at an increased risk of getting colorectal cancer should talk to their doctor about when to begin screening, which test is right for them, and how often to get tested.
Several screening tests can be used to find polyps or colorectal cancer. The Task Force outlines the following colorectal cancer screening strategies. It is important to know that if your test result is positive or abnormal on some screening tests , a colonoscopy test is needed to complete the screening process. Talk to your doctor about which test is right for you.
Significance And Possible Application
Discoveries like this are pivotal because they allow for earlier detection and treatment. When it comes to most types of cancer, early detection is the key to treating it successfully.
Patients diagnosed with a localized stage colon cancer have a 90% chance of survival within five years . That drops to 71% after cancer has spread to neighboring organs and systems. It drops to 14% once it spreads to farther parts of the body.
With technology this accurate, doctors can gain a better insight into the development of colon cancer. More importantly, colon cancer mortality rates will drop significantly in the future, thanks to the possibility of early detection.
For patients, this translates to more affordable and comfortable methods of screening. As lead author doctor Wen-Sy Tsai notes, There is still some reticence among patients to use stool-based tests or have an invasive exam like colonoscopy to detect colorectal cancer. Our results may point to a solution.

Scans Plus Tumor Markers Detect Recurrences Earlier Than Either Alone In Colorectal Cancer Patients
According to an article recently published in the British Journal of Cancer, levels of tumor markers plus results from computed tomography scans predicted cancer recurrences earlier than either method alone among patients with colorectal cancer who had liver metastasis that had been surgically removed.
The liver is a very common site for colorectal cancer to spread-a condition referred to as liver metastasis. The surgical removal of liver metastasis provides the greatest hope for a cure among these patients however, long-term survival still remains unfavorable as a large majority of these patients will experience a recurrence of their cancer.
Generally, outcomes for cancer recurrences that are detected and treated in their earliest possible stages are better than outcomes for those treated at later stages. Therefore, the most accurate monitoring for recurrences among patients who have had liver metastasis surgically removed may ultimately result in optimal outcomes for these patients.
Researchers from London conducted a clinical trial to evaluate the effectiveness of CEA plus CA 19-9 and CT scans in monitoring for recurrences among patients with colorectal cancer. This trial included 76 patients who had liver metastasis surgically removed. The patients underwent CEA, CA 19-9 testing, and CT scans every three months following surgery for two years and every six months thereafter.

Plasma Insulin Blood Glucose And Insulin Resistance
In the MDC-CC all the blood and plasma samples were collected at the MDC-CC baseline by a trained nurse in the morning after 12 h of fasting, and plasma was separated and immediately frozen at 20 °C until analysed. Analyses were performed according to the clinical routines of the Department of Clinical Chemistry. Blood glucose was analysed using a routine hexokinase method. Insulin levels were measured in mIU/ml by a radioimmunoassay. The lowest limit for detection was 3 mlU/ml.
HOMA2-IR was calculated with the use of a HOMA2-IR calculator . In the analysis of HOMA2-IR, extreme values of blood glucose were excluded, as were extreme values of plasma insulin , thus leaving 4451 individuals for analysis of HOMA2-IR. From the remaining individuals 135 cases of CRC, 76 cases colon cancer, and 59 cases of rectal cancer were found.

Blood Test For Colon Cancer
A personalized blood test can detect colon cancer recurrence sooner than scans.
A personalized liquid biopsy test that detects circulating tumor DNA in the blood can help identify colorectal cancer patients who are likely to relapse after surgery, researchers reported at the ASCO Gastrointestinal Cancers Symposium. Around 25% of people with colorectal cancer will relapse, and spotting recurrence earlier can help doctors tailor treatment.
In a study of more than 200 people who underwent surgery for Stage I to III colorectal cancer, the patients tumor DNA was sequenced to identify mutations, and a Signatera customized ctDNA test was designed to track tumor-specific mutations in their blood samples over time.
Among 218 people who were tested before starting adjuvant, or post-surgery, chemotherapy, the ctDNA test found that 20 had molecular residual disease , or evidence of remaining cancer. Within this subgroup, 15 people relapsed. In contrast, just 14% of the 198 patients who tested MRD negative experienced recurrence. People with detectable ctDNA immediately after surgery had a particularly high risk of recurrence. Whats more, the Signatera test was better at detecting residual disease than a commonly used tumor biomarker test.

Lab Tests Of Biopsy Samples
Biopsy samples are sent to the lab where they are looked at closely. If cancer is found, other lab tests may also be done on the biopsy samples to help better classify the cancer and possibly find specific treatment options.
Gene tests: If the cancer has spread , doctors will probably look for specific gene changes in the cancer cells that might help determine which drugs will be more helpful in treatment than others. For example, doctors now typically test the cancer cells for changes in the KRAS,NRAS, and BRAF genes. Patients whose cancers have mutations in these genes typically do not benefit from treatment with certain targeted therapy drugs. In the case of tumors that have the BRAF V600E mutation, they are not only less likely to respond to certain targeted drugs, but may need a different type of targeted drug added for treatment to work.
MSI and MMR testing: Colorectal cancer cells are typically tested to see if they show high levels of gene changes called microsatellite instability . Testing might also be done to see if the cancer cells have changes in any of the mismatch repair genes . EPCAM, another gene related to MSH2, is also routinely checked with the 4 MMR genes.
Changes in MSI or in MMR genes are often seen in people with Lynch syndrome . Most colorectal cancers do not have high levels of MSI or changes in MMR genes. But most colorectal cancers that are linked to Lynch syndrome do.
Stool Tests For Colorectal Cancer
These tests include:
Stool DNA test: This test requires a prescription and is sold under the brand name Cologuard®. It is approved by the U.S. Food and Drug Administration to detect mutated DNA in the stool. The stool sample is collected at home and mailed to a laboratory. The test does not require special preparation or medication restrictions. A stool DNA test may be an acceptable alternative to a colonoscopy for some low-risk patients, but is not recommended for patients who have had polyps, a family history of colorectal cancer or other risk factors.
Fecal immunochemical test : This analysis uses antibodies to detect blood in the stool. This test may also be performed at home. Test kits include a brush or stick used to wipe the stool sample onto a test card. Some test kits offer results in minutes others are mailed to a lab. The FIT test does not require special preparation or medication restrictions.
Fecal occult blood test : This test uses the chemical guaiac to detect blood in the stool. Like the FIT test, a sample is wiped onto a test card. Results may be provided immediately or after the samples are sent to a lab. This test may also be performed at home and may require some dietary and medication restrictions.
All test results should be discussed with a doctor to determine the next steps in the diagnostic or staging process or to discuss whether treatment is required.

What Is Colorectal Cancer
Colorectal cancer is a disease in which abnormal cells in the colon or rectum divide uncontrollably, ultimately forming a malignanttumor.
Most colorectal cancers begin as a growth, or lesion, in the tissue that lines the inner surface of the colon or rectum. Lesions may appear as raised polyps, or, less commonly, they may appear flat or slightly indented. Raised polyps may be attached to the inner surface of the colon or rectum with a stalk , or they may grow along the surface without a stalk .
Colorectal polyps are common in people older than 50 years of age, and most do not become cancer. However, a certain type of polyp known as an adenoma is more likely to become a cancer.
Colorectal cancer is the third most common type of non-skin cancer in both men and women . It is the second leading cause of cancer death in the United States after lung cancer. In 2021, an estimated 149,500 people in the United States will be diagnosed with colorectal cancer and 52,980 people will die from it .
The Link Between Diabetes And Colon Cancer
Not counting skin cancer, colorectal cancer is thethird most common form of cancer and the third leading cause of cancer-related deaths in Americans. Colon cancer affects your large intestine, the last stage of the digestive tract. Colorectal cancer starts as small polyps that form inside your colon and can become cancerous with time.
Regular colonoscopies identify polyps in their early stages so they can be removed before they turn into cancer. People with Type 2 diabetes are at particular risk of developing cancerous polyps and should not skip their regular screenings.
At GastroDoxs in Houston, Texas, board-certified gastroenterologist Bharat Pothuri, MD is aware of the extra risk that people with diabetes face when it comes to colon cancer. Were available to help you optimize your lifestyle so you reduce your risk of colon cancer. We also provide screenings to catch it early and offer expert management if you should receive a diagnosis.
Weve pulled together this information about the unique relationship between diabetes and colon cancer.

Tests To Look For Blood In Your Stool
If you are seeing the doctor because of anemia or symptoms you are having , a stool test might be recommended to check for blood that isnt visible to the naked eye , which might be a sign of cancer. These types of tests a fecal occult blood test or fecal immunochemical test are done at home, and require you to collect 1 to 3 samples of stool from a bowel movement. For more on how these tests are done, see Colorectal Cancer Screening Tests.
Gallbladder Or Liver Enlargement
If the cancer blocks the bile duct, bile can build up in the gallbladder, making it larger. Sometimes a doctor can feel this during a physical exam. It can also be seen on imaging tests.
Pancreatic cancer can also sometimes enlarge the liver, especially if the cancer has spread there. The doctor might be able to feel the edge of the liver below the right ribcage on an exam, or the large liver might be seen on imaging tests.

Your Blood Can Tell If You Have Colon Cancer
Colon cancer is the third most common cancer in the United States. The American Cancer Society predicts the cancer will cause 51,020 deaths in 2019 alone. However, the overall death rate is starting to drop, thanks to more advanced treatments developed over the last decade.
Detecting colon cancer with blood alone may have been an impossibility just a few years ago, but new developments are starting to suggest otherwise. Can blood tests diagnose colon cancer? A new discovery suggests that it may be possible by identifying circulating tumor cells in the blood.
Overall, colon cancer is still a difficult disease to identify, let alone treat. Multiple testing is often required to reach a conclusive diagnosis. But with a proactive attitude towards screening and testing, there are ways to significantly reduce the risk of developing colon cancer.
Dont Wait Until You Are 45 To Talk To Your Doctor About Screening
Reasons to get screened for colon cancer also include:
- If you are experiencing symptoms.
- If you have been diagnosed with inflammatory bowel disease .
- If your parents or immediate family members have had polyps, talk to your doctor about starting screening at an age 10 years before their polyps were discovered.
- If you have a family history of colon cancer or a genetic syndrome like Lynch syndrome or FAP .
Important! If you feel your concerns are being ignored by your current physician, dont be afraid to seek a second opinion and continue to request screening. You are your own best advocate and should feel empowered to take control of your health.
More information about screening options is available from the CDC.

Can A Blood Test Detect Colon Cancer
Colon cancer cant be directly identified from your blood alone. Blood tests are usually supplementary tests performed by doctors to understand your overall health. Trace elements from carcinogens can appear in your blood test results, which inform doctors about abnormalities in your body.
The common blood tests performed to detect colon cancer are:
Fecal occult blood test . Occult blood is blood that is invisible to the naked eye. A sample of your stool is studied to check for problems in the digestive tract. Positive results dont necessarily mean colon cancer benign tumors, ulcers, and other conditions concerning the digestive tract may also cause results to come back positive.
Carcinoembryonic antigen . The CEA is less of a test and more of a trace element. Cancerous cells sometimes produce this chemical in the blood. Doctors usually track the level of CEA in a patients body over a long period of time. This helps them understand how colon cancer is progressing in the body. Treatment efficacy is also based on long-term CEA levels.
