Why We Need Tailored Tobacco-control Strategies

Cigarette smoking is linked to 18 different types of cancer. It is the leading preventable cause of cancer in the United States, accounting for 19 percent of the 1,570,978 cancers diagnosed in U.S. adults ages 30 and older in 2014, according to the latest research. Another 0.4 percent of the cancer diagnoses in the U.S. that year were attributable to exposure to secondhand smoke.

That’s why February, which is National Cancer Prevention Month, is a good time to raise awareness of the dangers of cigarette smoking and exposure to secondhand smoke.

Could Genomics Influence Prostate Cancer Treatment?

Prostate cancer is one of the most common cancers diagnosed in the United States. About one-third of men diagnosed with prostate cancer have a tumor that grows very slowly, making it very unlikely that the disease will progress to become a clinical problem. Characterizing new ways to identify these cancers is an area of active research investigation.

Treating DNA Repair-deficient Breast Cancers

Several clinical trials are underway in which PARP inhibitors are being tested in breast cancers, mostly triple-negative breast cancers, because they often harbor BRCA mutations and DNA repair deficiencies. Emerging studies show that the benefit of PARP inhibitors could extend beyond breast cancers with germline BRCA mutations.

Recent Advances in Measuring Response to Immune Checkpoint Inhibitors

In recent years, the U.S. Food and Drug Administration has approved immune checkpoint inhibitors, a class of immunotherapy, to treat 10 different types of cancer, in addition to solid tumors located anywhere in the body that have certain DNA damage and repair-related biomarkers. However, only a small percentage of patients respond to these treatments, and they can have significant side effects. Researchers are looking for biomarkers that can identify patients who are likely to respond to immune checkpoint inhibitors.

Lessons Learned From Combining Anti-OX40 and Anti-PD1 Immunotherapies

A pair of studies published recently in journals of the American Association for Cancer Research bring to our attention the unexpected negative consequences of combining two immunotherapeutics concurrently, and discuss the mechanisms behind improved antitumor effects and survival outcomes with sequential administration of the two drugs.

News from the Cancer Centers: How DCIS Becomes Invasive Breast Cancer

Earlier this year, a study published in Cancer Discovery, a journal of the American Association for Cancer Research (AACR), explored the question of how preinvasive breast tumors become invasive. The study’s lead author, Kornelia Polyak, MD, PhD, discussed the findings in an article published by Inside the Institute, a publication of Dana-Farber Cancer Institute.
