What Is Stomach (Gastric) Cancer Screening?

Stomach cancer screening is a medical procedure that is aimed at detecting stomach cancer at an early stage or in individuals at higher risk of developing stomach cancer, before the onset of symptoms. In Singapore, stomach cancer is the 7th and 9th most common cancer and is common among older men. The primary purpose of stomach cancer screening is to identify any abnormal changes or cancerous growths in the stomach lining as early as possible, when the disease may be more treatable.

There are various methods used for stomach cancer screening including GASTROClear, a biomarker blood test, tumour marker blood tests such as Carcinoembryonic Antigen (CEA) and CA 19-9, and gastroscopy. Gastroscopy is the gold standard for gastric cancer detection that detects and diagnoses abnormalities in the food pipe, stomach and upper part of the small intestine.

GASTROClear™ Stomach Cancer Blood Test By MiRXES

GASTROClear™ by Singapore biotech firm MiRXES, is a biomarker blood test that makes it easy and convenient for people to get screened for the risk of stomach cancer. Minimally invasive and less time-consuming, it is a biomarker blood test that measures the levels of 12 microRNAs (genetic materials) in the blood that are associated with stomach cancer. The result from the GASTROClear test will tell whether the patient is at low risk, moderate risk or high risk of getting stomach cancer.

If the result shows that the patient has a low risk, he / she can get the test repeated yearly. However, if the result shows the patient is at moderate level, he / she can either repeat the test every 6 months or go straight to a gastroenterologist. If the test result shows high risk, a gastroenterologist should be consulted on doing a gastroscopy.

Who Should Take A GASTROClear Test?

According to Mirxes, the test may be taken by people of either sex, aged 40 years or older. They should be of “average risk” of getting stomach cancer (i.e. without symptoms of stomach cancer), but have one or more risk factors.

Gastroscopy Screening

A gastroscopy is an endoscopic procedure for detecting and diagnosing abnormalities in the food pipe, stomach and upper part of the small intestine. Gastroscopy is useful as it can help doctors to identify conditions that have yet to present any symptoms. Such conditions if left untreated could progress and become more difficult to treat. For instance, a H.Pylori infection could possibly lead to chronic inflammation in the stomach lining and result in cancer in the longer term.

Who Should Consider A Gastroscopy?

Individuals considering a gastroscopy should first consult a doctor. Some conditions that may indicate a need for the procedure include:

  • Aged 40 years and above with a family history of cancer or stomach ailments.
  • Experiencing upper abdominal pain.
  • Chronic heartburn or acid reflux.
  • Upper abdominal area pain or discomfort.
  • Unexplained weight loss.
  • Blood in the stool.
  • Iron deficiency anemia.
  • Experiencing pain when swallowing.

What Is Colorectal Cancer Screening?

In Singapore, colorectal cancer is the top killer cancer. Colorectal cancer screening aims for early detection and prevention of colorectal cancer, which includes cancers of the colon and rectum. Screening methods are employed to identify precancerous growths (polyps) or cancer at its earliest stages, often when it is more treatable or curable. 

Some of the common colorectal cancer screening methods include Fecal Immunochemical Test (FIT), tumour marker (CEA) and colonoscopy, the gold standard for colorectal cancer screening.

Colorectal Cancer Or Colon Cancer

Fecal Immunochemical Test (FIT)

FIT is considered a “preliminary” screening for colorectal cancer. It can detect the presence of small amounts of blood in faeces and can be nearly 80% accurate in detecting colorectal cancer. If the results are positive, the patient should follow up with further investigations to confirm the cause of the results. It is a simple, non-invasive test to undertake, and should be done annually.

Colonoscopy Screening

Colonoscopy screening for colorectal cancer is (to date) the best screening method as it enables the doctor to detect and remove the polyp before it becomes cancer.

Colonoscopy is a minimally invasive procedure for examining the inside of the colon. During colonoscopy, a colonoscope is inserted into the patient through the rectum. The colonoscope is a long, soft and flexible tube about 1 cm in width, with a small video camera located at the end. With this, the doctor can see the inside of the colon and diagnose any abnormality. The procedure may take about 20 – 30 minutes.

Polyps and other types of abnormal tissues that are discovered during a colonoscopy may be removed using the colonoscope during the procedure.

Who Should Screen For Colorectal Cancer?

The following table is based on MOH guidelines for colorectal cancer screening using colonoscopy in Singapore:

In some cases, both gastroscopy and colonoscopy may be ordered by a medical professional. It is often known as a “combined endoscopy” or “upper and lower endoscopy.”
