Upper GI endoscopy to look for signs of cancer. If any lesion is found, the tissue sample is collected for pathology evaluation (biopsy). Determining the extent (stage) of stomach cancer helps the doctor decide on the appropriate course of treatment.
CT– It is a diagnostic imaging procedure that uses x-rays to build cross-sectional images of the stomach. Intravenous contrast is injected to further characterise the gastric tumour and to look for its extent.
PET-CT– It is a tool used to provide more information in diagnosing primary gastric cancer and to look for any metastases to other organs, which helps in further management.
Blood Test – Tumour markers – Elevated levels of CEA (carcinoembryonic antigen) and CA 19-9 (cancer antigen) are associated with stomach cancer.
Pathology- The collected tissue sample is sent to the lab for further pathology evaluations such as Histopathological evaluation (HPE), Cytology and Immunohistochemistry (IHC).
