Comprehensive Colorectal Cancer Panel + MSI Test Cost & Procedure

Overview:

22 genes linked to a higher risk of hereditary colorectal cancer are examined by the Colorectal Cancer Comprehensive Panel (colon cancer). Both candidate genes with weak evidence of a relationship with colorectal cancer and genes with confirmed colorectal cancer susceptibility are included in this assay.

Adenomatous polyps, which are tiny, noncancerous (benign) clusters of cells, are the precursors to the majority of colorectal cancer cases. Some of these polyps could eventually develop into cancer. Polyps and colon cancer can be seen during a colonoscopy.

Hereditary colorectal cancer may be suspected if symptoms appear before age 50, a person develops more than one primary malignancy, or if numerous family members are affected. Both individuals with polyposis and those without polyposis of the colon should undergo this test. This testing may be suitable for some pediatric patients after taking into account a patient's clinical and family history. This test is intended to identify people who have a germline pathogenic variation, and it has not been proven to identify mosaicism below a 20% level. On tumor tissue, it shouldn't be requested.

These testing can be classified into two types:

Tests that examine the stool (or feces) look for indications of malignancy. These tests require more frequent administration despite being less intrusive and easier to perform.

Visual (structural) examinations: These tests look at the colon and rectum's structure to look for any abnormal spots. Both a scope—a tube-like tool with a light and tiny video camera on the end

The most prevalent hereditary colon candisorderseris Colorectal Cancer with Inherited non-polyposis (HNPCC).

Colon cancer and other malignancies are more likely to develop in people with HNPCC, also known as Lynch syndrome. Colon cancer is more likely to occur in HNPCC patients before age 50. family history of adenomatous polyposis (FAP)

Untreated FAP patients are at a significantly higher risk of having colon cancer before the age of 40.

Signs and indications

Colorectal cancer signs can incorporate the following.

Alters in bowel habits, like as chronic constipation or diarrhea, a sense that the intestines aren't emptying, a need to go, or a change in the consistency of the stools ( long, thin "pencil stools")

• Dark streaks of blood in the feces or leaking from the genitalia
• stomach pain, bloating, cramps, or any persistent abdominal discomfort
• unexplained exhaustion, weakness, appetite loss, or weight loss
• Pelvic pain, which manifests in the disease's latter stages.

Diagnosis

Hemogram of blood to screen for anemia.

As colon cancer frequently spreads to the liver, liver enzymes can be tested.

If the symptoms are very suggestive, a colonoscopy is typically utilized to make the diagnosis of colorectal cancer.

Any questionable area is sampled for biopsy tissue during colonoscopy.
