Page last updated: 25 July 2024

Application Detail

Description of Medical Service

A test to determine the Claudin (CLDN18.2) status of patients with locally advanced unresectable or metastatic human epidermal growth factor receptor 2 (HER2) negative gastric or gastro-oesophageal junction adenocarcinoma. The test is an assay and will be performed as part of the diagnostic biopsy. The results of the test will determine whether the patient will be eligible for treatment with PBS subsidised zolbetuximab.

Description of Medical Condition

Gastric or gastro-oesophageal junction cancer occurs in the epithelial lining of the stomach and the gastro-oesophageal junction between the stomach and the oesophagus. Tumours in the gastro-oesophageal junction may be classified as either gastro-oesophageal junction cancer or oesophageal cancer, depending on how far from the junction they arise. Cancer is considered HER-2 negative if the cancer cells do not have abnormal levels of HER2 proteins.
