Immunotherapy for triple negative breast cancer

Treatments that unleash the immune system against cancer have been a hot topic for the last few years, but they do not appear in our recent feature on breast cancer for Winship Cancer Institute’s magazine.

Partly, that’s because decent avenues for treatment exist for most types of breast cancer, with improvements in survival since the 1980s. Immunotherapy’s successes have been more dramatic for types of cancer against which progress had been otherwise meager, such as lung cancers and metastatic melanoma.

However, for “triple-negative” breast cancer (TNBC) in particular, immunotherapy could be a good match, because of the scarcity of targeted treatments and because TNBC’s genomic instability may be well-suited to immunotherapy.

Winship oncologists Jane Meisel and Keerthi Gogineni inform Lab Land that several early-phase clinical studies open to breast cancer patients, testing “checkpoint inhibitor” agents such as PD-1 inhibitors, are underway. More are pending.

Meisel’s presentation at Winship’s Sea Island retreat says that immunotherapy is “not yet ready for prime time, but a very promising experimental approach for a subset of patients for whom current therapies are not sufficient. We need to better understand which subsets of patients are most likely to benefit, and how we can use other therapies to enhance efficacy in patients who don’t initially respond.”
