Carolinas HealthCare System’s Levine Cancer Institute was featured in the New England Journal of Medicine for its prominent role in research that advances the treatment of advanced-stage lung cancer. Daniel Haggstrom, MD, is a medical oncologist at the Institute and co-author of the study, which demonstrated the efficacy of a molecular-targeted therapy, AZD9291, in patients with advanced-stage lung cancer.

Non-small cell lung cancer (NSCLC) is the leading cause of cancer mortality in the United States. Historically, treatments were limited to chemotherapy or radiation therapy if surgery cannot be performed. With advances in molecular testing and through clinical trials, oncologists are finding new targeted therapies that work very well for some patients with much less toxicity. The drug, AZD9291, targets a specific gene mutation, which makes the preferred first line therapy for this subset of patients ineffective.

Of the patients enrolled in the study who had developed a resistance to previous medication and were instructed to take the pill, AZD9291, once a day, 80 percent experienced tumor shrinkage or stability with manageable side effects.

“We are seeing amazing results with this treatment. Patients are living longer, with an improved quality of life compared to traditional chemotherapy, and the side effects of AZD9291 are very manageable,” said Dr. Haggstrom, principal investigator of the study at Levine Cancer Institute. “It is an exciting time in cancer care and, in particular, lung cancer. Through research and clinical trials, we are tailoring our therapies to improve outcomes and limit adverse side effects.”

EGFR, or epidermal growth factor receptor, is a protein that exists on the surface of both cancer cells and normal cells. In some cancer cells this receptor develops a mutation, yielding constant activation of EGFR and uncontrolled cell division and growth of cancer. In lung cancer patients whose tumors possess EGFR mutations (approximately 10 to 15 percent of patients in the US) molecularly targeted oral therapy is a preferred first treatment option.

Unfortunately, these patients with EGFR- driven lung cancer eventually develop resistance to first line treatment, which previously meant revisiting non-targeted therapies, such as chemotherapy and radiation therapy. In nearly half of the patients who develop this resistance, a specific genetic mutation, T790m, is responsible. AZD9291 directly targets this pathway resulting in a reduction in the size and growth of the non-small cell lung cancer, and secondary to its efficacy in this population received “breakthrough” status by the FDA for extending progression-free survival.

“Identifying genetic mutations specific to a patient’s individualized tumor and giving the appropriate treatment is the future,” said Edward Kim, MD, Chair of Solid Tumor Oncology at Levine Cancer Institute.

Diagnosed with only months to live, Edwina was enrolled in a study that analyzed the genetics of her tumor and then took aim at a specific mutation. A year later, Edwina’s cancer is shrinking and she’s literally back on her feet.
