Study: A win for some patients with HER2-negative metastatic breast cancer

A drug used to treat HER2-positive breast cancer improved survival in people with metastatic breast cancers that were previously considered HER2-negative. These results change practice guidelines for metastatic breast cancer and reclassify HER2 tumor marker status as “HER2-low” to guide treatment. (Posted 7/18/22)

Update: On 08/05/2022 the FDA approved Enhertu to treat people with metastatic, HER2-low breast cancer who have received prior chemotherapy in the metastatic setting or who developed disease recurrence during or within six months of completing chemotherapy. Enhertu is also approved for treatment of people with metastatic HER2-positive breast cancer who progressed after prior anti-HER2 treatment. Este artículo está disponible en español.

Update: Blood tests called liquid biopsies for cancer screening, monitoring and treatment

Could a simple blood test change cancer detection, treatment and monitoring? Several companies are offering a type of blood test known as a liquid biopsy to detect multiple cancers at their earliest stages, monitor response to treatment and help choose the best treatment. Although progress has been made using liquid biopsies to treat cancer, these tests have not yet been shown to detect cancer early enough to save lives. (posted 9/29/21)

Study: Test score may predict which prostate cancer patients can safely skip combined therapy

This study shows that a test score that estimates the aggressiveness of a person’s prostate cancer may also identify the best treatment for patients. (posted 7/9/21)

Study: Can tumor tests identify more breast cancer patients who can safely skip chemotherapy?

Two studies presented at the December 2020 San Antonio Breast Cancer Symposium looked at how tumor testing can identify patients who may benefit the most and the least from chemotherapy. (3/4/21)

Update: FDA approves new imaging drug for detecting spread of prostate cancer

On December 1, 2020 the FDA approved a new type of imaging technology to confirm the spread of newly diagnosed prostate cancer that is suspected to be metastatic. The approval also includes use for confirming suspected recurrence in men who have rising PSA after treatment. The approval is based on two clinical trials that showed this new technique to be safe and consistent in accurately detecting cancer that has spread beyond the prostate gland. (1/7/21)

THIS INFORMATION HAS BEEN UPDATED on 5/10/2022:  On March 23, 2022 the U.S. Food and Drug Administration (FDA) approved a new drug called Pluvicto to treat patients with metastatic castration-resistant prostate cancer. ON the same day, the FDA also approved a new imaging drug called Locametz (a brand of Gallium 68 PSMA-11) for identification of those patients who would benefit from treatment with Pluvicto. Read about the FDA approval of Pluvicto and Locametz here.

Update: FDA approves the PARP inhibitor olaparib (Lynparza) in combination with bevacizumab (Avastin) as maintenance therapy for some women with advanced ovarian cancer

The FDA has approved the first drug combination to be used as a first-line maintenance therapy for some women with advanced ovarian cancer. (7/7/2020)

Study: Promising research using a PARP inhibitor to treat metastatic breast cancer in people with an inherited PALB2 mutation or a tumor mutation in BRCA1 or BRCA2

Early results of a small study showed that women with metastatic breast cancer and an inherited  mutation in PALB2 or an acquired tumor mutation in BRCA1 or BRCA2 benefitted from the PARP inhibitor olaparib (Lynparza). (6/18/20)

Study: Declining use of chemotherapy for early-stage breast cancer: examining oncologist recommendations

A new study shows that chemotherapy use for early-stage, node-positive and node-negative breast cancers declined from 2013 to 2015. It also reports that oncologists’ recommendations are influenced to differing degrees by patient preferences and tumor test results, despite unchanging health care guidelines. (8/21/18)

Study: Some women with early-stage breast cancer forego chemotherapy

A research study named the “Trial Assigning Individualized Options for Treatment” (TAILORx) asked whether chemotherapy is beneficial for women who have mid-range Oncotype DX tumor recurrence scores. This trial — the largest breast cancer treatment trial ever conducted— showed that endocrine therapy alone was as effective as endocrine therapy plus chemotherapy in women with certain types of early-stage breast cancer. The results of this trial are expected to be immediately practice changing (7/20/18)

Guideline: Can MammaPrint guide treatment decisions?

The American Society of Clinical Oncology (ASCO) updated its guidelines for MammaPrint, a genomic tumor test that guides treatment decisions for patients with early-stage invasive breast cancer. The update was based on results from the MINDACT study (11/16/17).
