Sacituzumab Govitecan Demonstrates Durable Responses in Metastatic TNBC

Excerpt:

“Sacituzumab govitecan (IMMU-132) was well tolerated and demonstrated early and durable responses in heavily pretreated patients with metastatic triple-negative breast cancer (mTNBC), according to the results of a recent phase I/II study published in the Journal of Clinical Oncology.

“Sacituzumab govitecan is an antibody–drug conjugate that targets Trop-2, which is expressed in more than 90% of TNBCs, by selectively delivering SN-38, the active metabolite of irinotecan. It was granted a breakthrough therapy designation by the FDA in February 2016 for the treatment of patients with mTNBC, following at least 2 treatments for metastatic disease.”

Neoadjuvant T-DM1 Improves pCR in HER2+/HR+ Early Breast Cancer

Excerpt:

“Twelve weeks of neoadjuvant T-DM1 (ado-trastuzumab emtansine; Kadcyla) with or without endocrine therapy induced superior pathologic complete response (pCR) compared with trastuzumab (Herceptin) plus endocrine therapy in patients with HER2-positive/HR-positive early breast cancer, according to findings recently published online in theJournal of Clinical Oncology.

“In the prospective, neoadjuvant phase II ADAPT trial conducted by the West German Study Group, pCR was 41.0% for patients assigned to T-DM1 alone and 41.5% for those who received T-DM1 and endocrine therapy. In contrast, 15.1% of patients assigned to trastuzumab and endocrine therapy had a pCR (P<.001).”

Young Breast Cancer Patients Undergoing Breast Conserving Surgery See Improved Prognosis

Excerpt:

“A new analysis indicates that breast cancer prognoses have improved over time in young women treated with breast conserving surgery. The analysis included 1331 patients younger than 40 years treated with breast conserving surgery and whole breast radiotherapy in a single cancer centre in Italy between 1997 and 2010.

“Breast cancer recurrences and deaths significantly decreased over time. A dramatic improvement in prognosis was observed after 2005, when the use of several new diagnostic and  were implemented in routine clinical practice.”

Using Alternative Medicine Only for Cancer Linked to Lower Survival Rate

Excerpt:

“Patients who choose to receive alternative therapy as treatment for curable cancers instead of conventional cancer treatment have a higher risk of death, according to researchers from the Cancer Outcomes, Public Policy and Effectiveness Research (COPPER) Center at Yale School of Medicine and Yale Cancer Center. The findings were reported online by the Journal of the National Cancer Institute.

“There is increasing interest by  and families in pursuing alternative medicine as opposed to conventional  treatment. This trend has created a difficult situation for patients and providers. Although it is widely believed that conventional cancer treatment will provide the greatest chance at cure, there is limited research evaluating the effectiveness of alternative medicine for cancer.”

Anti-Inflammatory, Anti-Stress Drugs Taken Before Surgery May Reduce Metastatic Recurrence

Excerpt:

“Most cancer-related deaths are the result of post-surgical metastatic recurrence. In metastasis, cells of primary tumors travel to other parts of the body, where they often proliferate into inoperable, ultimately fatal growths.

“A new Tel Aviv University study finds that a specific drug regimen administered prior to and after surgery significantly reduces the risk of post-surgical cancer recurrence. These medications, a combination of a beta blocker (which relieves stress and high blood pressure) and an anti-inflammatory, may also improve the long-term survival rates of patients. The treatment is safe, inexpensive—two medications similar in price to aspirin—and easily administered to patients without contraindications.”

Testing for Immune ‘Hotspots’ Can Predict Risk That Breast Cancer Will Return

Excerpt:

“Scientists have developed a new test that can pick out women at high risk of relapsing from breast cancer within 10 years of diagnosis.

“Their study looked for immune cell ‘hotspots’ in and around tumours, and found that women who had a high number of hotspots were more likely to relapse than those with lower numbers.

“The new test could help more accurately assess the risk of cancer returning in individual patients, and offer them monitoring or preventative treatment.”

Targeted Radiotherapy Limits Side Effects of Breast Cancer Treatment

Excerpt:

“Breast cancer patients who have radiotherapy targeted at the original tumour site experience fewer side effects five years after treatment than those who have whole breast radiotherapy, and their cancer is just as unlikely to return, according to trial results published* in The Lancet (link is external) today (Wednesday).

“The Cancer Research UK-funded IMPORT LOW trial** revealed that five years after treatment, almost all patients were disease free.***

“The researchers at 30 radiotherapy centres across the UK, led by The Institute of Cancer Research, London(link is external), and the Cancer Research UK Cambridge Centre(link is external), studied more than 2,000 women aged 50 or over who had early stage breast cancer that was at a low risk of coming back.”

New Online Navigator Helps Patients and Doctors Access Experimental Treatments

Excerpt:

“When approved therapies don’t work, or stop working, for people with serious or life-threatening illnesses, it puts them in a difficult position. Some turn to clinical trials that are testing experimental treatments. But many can’t do that because they are too sick, don’t meet the requirements of the trial, or can’t afford to travel to the site of a trial. That doesn’t mean they are out of options.”

Immune Checkpoint Agents Advance in Breast Cancer

Excerpt:

“With the prospect of phase III data that could confirm their efficacy, checkpoint inhibitors against PD-1 and PD-L1 have shown promise, both as monotherapies and in combination with chemotherapy for patients with triple-negative breast cancer (TNBC), Sylvia Adams, MD, said during a presentation at the 16th Annual International Congress on the Future of Breast Cancer East.

” ‘We think there is definitely value for immune checkpoint blockade in triple-negative disease. When you look at the metastatic trials, while the response rates are relatively low, most of the responses are durable,’ said Adams, from the NYU Langone Medical Center. ‘For patient selection, it is important to consider the line of therapy. The earlier the better.’ ”
