Validation of a low-cost and high throughput assay for Lynch syndrome screening in patients with cutaneous sebaceous tumours

Lynch syndrome is the commonest cause of cancer running in families, particularly cancers of the bowel and womb as well as a rare type of skin tumour of the sebaceous glands. People who have Lynch syndrome benefit from life-saving cancer prevention and routine cancer surveillance, but less than 10% have a diagnosis.

The NESRF award is supporting my research into the application of a novel diagnostic test for sebaceous tumours to screen for Lynch syndrome. This test, the Newcastle MSI-Plus Assay, was initially developed for automatable, low cost, and high-throughput analysis of bowel cancers and is currently used by the NHS to test over 5000 bowel cancers each year. Showing it can also be used in sebaceous tumours will allow streamlining of clinical practice by incorporating sebaceous tumour testing into established diagnostic pipelines, ultimately leading to increased Lynch syndrome diagnoses.

This project feeds into a broader campaign to improve Lynch syndrome screening of patients with sebaceous tumours as well as my ongoing and future research to improve the detection and care of mismatch repair deficiency-related cancer syndromes.
