Every woman diagnosed with early-stage breast cancer faces a decision about what type of surgery to have. Together with her doctors, she will have to choose between breast-conserving surgery (BCS), also called lumpectomy, and mastectomy. BCS preserves the breast, removing the tumor and a rim of surrounding tissue, whereas mastectomy removes the entire breast. Patients with early-stage disease (with the… Read more »

Androgen deprivation therapy (ADT) has long been a mainstay in the management of prostate cancer. Indeed, the vast majority of prostate cancers depend on androgens (hormones like testosterone) for their growth. Lowering testosterone levels with ADT is a reasonable approach. But it comes with two sets of problems.

In recent years, many people with non-small cell lung cancer (NSCLC) have been successfully treated with drugs called EGFR inhibitors. But over time, most patients develop resistance to these drugs, and the drugs stop working. Researchers are hard at work developing new drugs to help patients who can no longer be treated with EGFR inhibitors.

Pertuzumab (Perjeta) is a relatively new drug that targets HER2, a protein found at higher-than-normal levels in about 15% to 20% of all breast cancers. Too much HER2 leads to tumor growth. Currently, all newly diagnosed breast cancer patients have their tumors’ HER2 levels tested. Knowing whether a patient’s HER2 levels are abnormally high (HER2-positive) or normal (HER2-negative) is a major factor in choosing a treatment, thanks to the availability of trastuzumab (Herceptin) and, now, other HER2-targeted drugs such as Perjeta, T-DM1 (Kadcyla), and lapatinib (Tykerb). These drugs are all used to treat HER2-positive patients.
