Stomach cancer is a common cancer globally, and early detection is essential for better treatment outcomes. In Singapore, it is the sixth cause of cancer deaths in men and the seventh in women. Understanding the various stomach cancer tests available is crucial for taking proactive steps towards early diagnosis. In this article, we will explore the different stomach cancer tests including GastroClear, a blood test that is gaining attention in the medical community.
Why Stomach Cancer Screening Is Important
Stomach cancer, also known as gastric cancer, often develops slowly over many years. The early stages typically present no symptoms, making it difficult to detect until the disease has advanced. Regular screening, especially for those at higher risk, can lead to early diagnosis and significantly better treatment outcomes.
Understanding The Risk Factors
Before discussing the tests, it is important to understand the risk factors associated with stomach cancer. Key risk factors include:
- Family history of gastric cancer.
- Personal history of Helicobacter pylori infection.
- Chronic gastritis.
- High consumption of fried foods, smoked foods, salted fish, processed meats, and pickled foods.
- Consumption of foods containing nitrites and nitrates, commonly found in cured meats.
- Low consumption of fruits and vegetables.
If you fall into one or more of these categories, it is advisable to consult a doctor about regular stomach cancer screening.
Common Stomach Cancer Tests In Singapore
Several diagnostic tests are available in Singapore to detect stomach cancer. Here are some of the most commonly used:
1. GastroClearâ„¢
GASTROClear by MiRXES is a stomach cancer blood test – the first of its kind in the world designed to detect stomach cancer in individuals who may not yet be experiencing any symptoms. GASTROClear is the result of an international collaboration led by the Singapore Gastric Cancer Consortium (SGCC) and involved researchers and clinicians from Singapore and South Korea. Unlike traditional methods that are invasive, GastroClear offers a non-invasive, easy-to-administer option.
How GastroClear Works
Diseases such as cancer, often result in abnormal levels of certain associated biomaterials called microRNAs in the blood. GASTROClear measures the levels of 12 microRNAs in the serum that are produced by stomach cancer cells. By using GASTROClear, doctors can assess a patient’s risk of stomach cancer even before symptoms become apparent.
Advantages Of GastroClear
- Non-Invasive – Unlike endoscopy, GastroClear only requires a blood sample.
- High Accuracy – GASTROClear has been validated to exhibit a sensitivity of 82% and a specificity of 88% in detecting stomach cancer among asymptomatic, average-risk individuals in Chinese and South Korean populations. In a symptomatic, high-risk population in Singapore, GASTROClear demonstrated sensitivities of 87.5% for stage I and 89.5% for stage II stomach cancer, while maintaining a specificity of 68.4%.
- Convenience – The test can be done at clinics and hospitals in Singapore without the need for hospitalisation.
Who Should Consider GastroClear?
GastroClear is particularly suitable for individuals who are at higher risk of stomach cancer, such as those with a family history or chronic H. pylori infection. It is also ideal for those who prefer a non-invasive test or are unable to undergo an endoscopy for medical reasons.

2. Endoscopy
An endoscopy involves inserting a thin, flexible tube with a camera down the throat to examine the stomach. It allows doctors to see the stomach lining and take biopsies of any suspicious areas. This is the gold standard for diagnosing stomach cancer.
3. Biopsy
During an endoscopy, if any abnormalities are found, a biopsy may be taken. This involves removing a small piece of tissue to be examined under a microscope for cancer cells.
4. Barium Swallow
A barium swallow test involves swallowing a liquid that coats the stomach lining, making it easier to see abnormalities on X-rays. However, it is less commonly used now compared to endoscopy.
5. CT Scan
Computed Tomography (CT) scans provide detailed images of the stomach and can show the extent of cancer spread. It is often used in conjunction with other tests.
