How effective is genomic tumour profiling for ovarian cancer?

Testing examines tumour DNA or related features to look for changes that may affect treatment choices. Some results suggest a targeted option or a trial; others are uncertain or do not currently change care. Tumour testing is different from inherited genetic testing. If the report raises the possibility of an inherited change, your clinician may offer genetic counselling and a separate germline test because that information can matter to relatives as well as to your own care.

Ask whether the sample is adequate and whether testing should happen before a treatment decision. Bring the report to the oncology appointment and ask which findings are clinically meaningful rather than merely listed. Discuss how a proposed treatment fits your cancer’s stage, previous medicines, symptoms, and general health. Keep a record of the test date and sample source, since a later biopsy may be considered if the cancer changes.

Seek urgent medical advice for severe abdominal swelling or pain, repeated vomiting, fainting, new breathlessness, or inability to pass urine or stool. These symptoms need clinical assessment and should not wait for a profiling report. During treatment, follow your oncology service’s instructions for fever, sudden weakness, or other rapidly worsening symptoms.

Could this test change my next treatment? Does the result suggest inherited testing? Which findings are actionable now, and how will we check whether a chosen treatment is helping?
