1787 – Immunohistochemistry testing of solid tumour tissue to determine folate receptor alpha (FRɑ) expression status in adults with platinum-resistant ovarian cancer, to determine eligibility for treatment with PBS subsidised mirvetuximab soravtansine

Page last updated: 27 September 2024

Application Detail

Description of Medical Service

Folate receptor alpha (FRɑ) is a protein that is expressed in nearly all ovarian cancers and can be overexpressed in ovarian cancer solid tumours while being minimally expressed in normal tissue. The FRɑ-positive expression status may be determined using a validated immunohistochemistry (IHC) assay to detect the percentage of viable tumour cells with membrane staining for FRɑ. The test is used to determine eligibility for a potential new PBS subsidised treatment, mirvetuximab soravtansine.

Description of Medical Condition

The proposed treatment is intended for adults with epithelial ovarian, fallopian tube, or primary peritoneal cancer whose tumours are FRɑ-positive and are resistant to treatment with a platinum- containing chemotherapy regimen. Epithelial ovarian cancer is the most common type of ovarian cancer accounting for 90% of ovarian cancer cases.
