Millions of breast cancer patients could avoid chemotherapy with new genome test

TL;DR · WeSearch summary

A new genomic test could allow millions of breast cancer patients to avoid chemotherapy. The test identifies which patients are unlikely to benefit from chemotherapy, thus sparing them from its side effects. Clinical trials have shown that patients who do not receive chemotherapy have similar outcomes to those who do.

Key facts

▪The genomic test, called Prosigna, measures gene activity related to breast cancer growth.
▪In a trial, over 4,400 participants were assessed to determine their need for chemotherapy after surgery.
▪Results indicated that 94.8% of patients receiving chemotherapy were alive and free from recurrence, compared to 93.6% of those who did not receive it.
