    New Trends in Pre-Surgery Treatments for Breast Cancer

    Emma Shtivelman, PhD

    Non-metastatic breast cancers are most often treated with surgery, but if the tumors are fairly large, or involve nearby lymph nodes, neoadjuvant (pre-operative) treatments with chemotherapy (NAC) are done first. NAC often reduces the tumor size and kills cancer cells in lymph nodes, if present, prior to surgery, improving the outcome. The best possible result of neoadjuvant treatment is pCR (pathologic compete response), when… Read more »

    ASCO 2017: Breast Cancer Treatment News

    Emma Shtivelman, PhD

    Last month, the annual American Society of Clinical Oncology (ASCO) meeting took place in Chicago. Thousands of oncologists, patients, and journalists gathered to learn about the most recent developments in cancer research and treatment. Here are some breast cancer highlights from the meeting: Triple negative breast cancer (TNBC) is considered more responsive to treatment with immune checkpoint drugs than any other type of breast cancer.… Read more »

    Putting Immune Checkpoint Blockade to the Test in Breast Cancer

    Emma Shtivelman, PhD

    About 10 months ago, we asked: is there a future for immunotherapy in breast cancer? Now, we can answer this question with a qualified “yes.” The data show why.

    To PD-L1 or Not to PD-L1: That Is the Question

    Emma Shtivelman, PhD

    These days, it seems that I write mostly about immune checkpoint blockade drugs, or some other new immunotherapy treatment for cancer. This post is no different—it covers PD-L1, a protein that is at the center of clinical decisions for selecting patients who are likely to benefit from treatment with an anti-PD-1 or anti-PD-L1 drug.

    What Determines Whether a Melanoma Patient Will Respond to Checkpoint Blockade Drugs?

    Emma Shtivelman, PhD

    Of all cancer types, melanoma is the most investigated in terms of its potential to be treated through immune system-based approaches. More immunotherapy drugs are approved for melanoma than for any other type of cancer, and more are in development. Recent additions to the immunotherapy arsenal are the ‘anti-PD-1’ immune checkpoint blockade drugs pembrolizumab (Keytruda) and nivolumab (Opdivo).

    Melanoma at ASCO 2015: Immunotherapy Continues to Make Headlines

    Emma Shtivelman, PhD

    The biggest news in melanoma treatment from the 2015 American Society of Clinical Oncology (ASCO) annual meeting was undoubtedly the report from a large, phase III, randomized clinical trial that compared a combination of two ‘checkpoint inhibitor’ drugs—nivolumab (Opdivo) and ipilimumab (Yervoy)—with the same drugs given alone. In the CheckMate-067 trial, 945 previously untreated patients with unresectable stage III or IV melanoma were assigned… Read more »

    ‘Immune Checkpoint’ Drugs Show New Promise for Treating Non-Small Cell Lung Cancer

    Emma Shtivelman, PhD

    It has become routine practice to prescribe targeted drugs to patients with metastatic non-small cell lung cancer (NSCLC), whose tumors harbor molecular alterations in EGFR, ALK, and ROS. However, the majority of patients with NSCLC have no targetable mutations and lack good treatment options. Enter immunotherapy drugs, specifically ‘immune checkpoint blockade antibodies,’ to which many refer simply as ‘anti-PD-1 drugs,’ or simply ‘PD-1 drugs.’… Read more »

    Immune Checkpoint Inhibitors in Melanoma: New Directions

    Emma Shtivelman, PhD

    The drugs pembrolizumab (Keytruda) and nivolumab (Opdivo) were approved by the U.S. Food and Drug Administration (FDA) in 2014 and 2015, respectively. These two competing blockbuster drugs are already changing the outlook in metastatic melanoma, previously considered to be a fatal disease. Known as ‘immune checkpoint inhibitors,’ they work by releasing ‘brakes’ on a patient’s own immune system, freeing it to attack tumors. In the wake of their success, researchers are now taking immune checkpoint inhibition in new directions.
