Despite unstinting interventions such as chemotherapy and surgical tumor removal, approximately 40% of patients with stage I-III triple-negative breast cancer (TNBC) will experience tumor recurrence. Fortunately, not all hope is lost. The advent of immune checkpoint blockade (ICB) immunotherapy—a type of therapy that uses one’s own immune cells to kill the cancer—has shown great promise for the treatment of TNBC. However, as Dr. Azra Raza says in her book, The First Cell: And the Human Costs of Pursuing Cancer to the Last, these “immune approaches are not universally curative and, at present, help very few patients.”

Sensing tension in the brain tumor microenvironment
According to Azra Raza, a Professor of Medicine at Columbia University in New York, high-grade brain cancer called glioblastoma is “one of the most aggressive, ruthless killers known to mankind”. Indeed, despite recent advances in cancer therapies, glioblastoma remains incurable with a median survival of 15 months which has not improved substantially in the last 20 years. This poor prognosis is, in part, due to the highly immunosuppressive microenvironment that allows tumors to evade anti-tumor immune response and promotes resistance to immunotherapy – a kind of therapy that uses your body’s own immune system to find and eliminate tumor cells.

What if scientists could treat cancer without the extreme side effects of chemotherapy? Could scientists create a tiny way to cure a giant health crisis? Nanoparticle drug delivery systems could be the answer to our prayers.
