Around the Web

Just when I start to think most of my anger toward cancer has dissipated, a dear friend sends me an email about her colleague's wife who just learned that her early-stage cancer is now metastatic. Meaning, it has spread to bones or vital organs. It is incurable. I don't know this woman's health history, but I do know her cancer was first diagnosed in 2007. So, more than SEVEN years later, after I'm sure she figured she was done with this disease, barely a speck in her rearview mirror any longer, it rears its hideous head again.

Then I learned of another woman, a mom to two young children, who died this weekend after battling triple negative breast cancer for a little over a year. One year. If you want to contribute to her family as they try to navigate through life in the absence of their wife, mom, daughter, best friend, the link to do so is here.

And if you've ever been tempted to say (as I was and did, when I was first diagnosed) that, well, everyone beats breast cancer, please think again. As the first article in this week's round-up reminds us, we still have so much work to do. Also, if you find anything you think I should include here, please shoot me an email. I'd love to hear from you.

Pretty in Pink? A Reminder That We Still Have Work to Do in the Fight Against Metastatic Breast Cancer

(Full disclosure: I'm quoted a couple of times in this article.)

"According to the American Cancer Society, the 5-year survival rates for stages I, II and III breast cancer are 100 percent, 93 percent and 72 percent respectively, and not all early stage breast cancers will advance to stage IV....

In contrast, 75 percent of people diagnosed with metastatic breast cancer will die of the disease within five years."

But There's Reason (in the form of Personalized Medicine) for Hope

"Even more tailored treatment is on the horizon. In the next few years, patients with breast cancer can expect increasingly detailed diagnostic tests, tests that may predict side effects of treatments like chemotherapy or radiation, and better guidance in choosing the drug, or drugs, most likely to eradicate their disease. Genomic discoveries may also help patients with advanced, aggressive cancers, a group for whom even the latest treatments often fail. In these ways and many others, breast cancer prevention, treatment, and care are a microcosm of the slow but inevitable shift in healthcare....

'We are at the beginning of a revolution,' says the American Cancer Society’s Lichtenfeld. 'Breast cancer, as with many others — lung, melanoma, etc. — has a number of therapies in the pipeline, and that number is increasing dramatically. What does the future hold? Some successes, some failures. Will it lead to a cure? I can’t say that. Will it lead to control of breast cancer? That’s a real possibility.'"

A "Novel Platform" for the Treatment of Pancreatic and Breast Cancers

"Scientists from the Florida campus of The Scripps Research Institute (TSRI) have identified a novel synthetic compound that sharply inhibits the activity of a protein that plays an important role in in the progression of breast and pancreatic cancers.

In the new study, to be published in the February 2015 print edition of the journal Molecular Pharmacology, the scientists showed that the compound, known as SR1848, reduces the activity and expression of the cancer-related protein called "liver receptor homolog-1" or LRH-1.

In fact, the study showed that levels of LHR-1 in a cell's nucleus began to diminish four hours after treatment with SR1848, and the compound repressed specific target genes as early as two hours after administration."

Rates of Diagnosis and Survival Vary by Race

"A new study published in JAMA finds that among women in the US, the chance of being diagnosed with breast cancer in the early stages of the disease and the likelihood of surviving after such a diagnosis may be influenced by race and ethnicity, and this may be down to biological differences."

Around the Web

Call me naive, but I didn't know it would be quite this hard to introduce our cat to our dog. The cat has spent the better part of the last week holed up in a closet in one of our bedrooms. But Luna-Dune, as we've all started calling her, is fitting in with our family nicely. Most importantly, she appears to have sated my urge to have/adopt/somehow acquire another child. This is exhausting enough, thank-you-very-much.

(But look how cute she is...)


When I wasn't busy Instagramming photos of my dog, here's what caught my attention on the internet this week.

Breast Cancer Vaccine Shows Promise (but Phase II Trial Will Exclude Advanced-Stage Patients)

This makes me both hopeful and terribly sad that metastatic patients won't be included in the next phase of research.

"If we give the vaccine to patients at the beginning of treatment, the immune systems should not be compromised like in patients with metastatic disease," Gillanders said. "We also will be able to do more informative immune monitoring than we did in this preliminary trial. Now that we have good evidence that the vaccine is safe, we think testing it in newly diagnosed patients will give us a better idea of the effectiveness of the therapy."

Did You Hear What Melissa Etheridge Said About Breast Cancer?

That her words "stirred debate" is a bit of an understatement, at least in the breast cancer community.

"Singer Melissa Etheridge's comments that breast-cancer genes can be turned on or off by diet are being challenged by doctors and others, who say they are hurtful and could mislead millions of people."

And Speaking of Genetic Screening...

"Most patients with triple-negative breast cancer should undergo genetic testing for mutations in known breast cancer predisposition genes, including BRCA1 and BRCA2, a Mayo Clinic-led study has found. The findings come from the largest analysis to date of genetic mutations in this aggressive form of breast cancer. The results of the research appear in the Journal of Clinical Oncology."

And Speaking of Triple Negative Breast Cancer...

"Scientists at A*STAR's Genome Institute of Singapore (GIS), in collaboration with local clinicians and colleagues in the USA, have identified a biomarker which is strongly associated with triple negative breast cancer (TNBC), a highly aggressive carcinoma that often has early relapse and metastasis following chemotherapy. The newly identified biomarker, a gene called RASAL2, provides a target for developing new therapeutics designed to treat this often deadly disease."

Saying Good-Bye Far Too Young

Another mother gone too soon because of metastatic, triple negative breast cancer.

"And who are the brave ones in the country's breast cancer conversation? They're so quiet as to be all but ignored. They're the women with metastatic disease, especially the young women I get chemo alongside at Dana-Farber Cancer Institute in Boston, the ones who really may not see their children graduate from kindergarten, let alone high school."

Another Reason I'm Lucky: Where I Live

"In the United States, 9 out of 10 kids diagnosed with acute lymphoblastic leukemia will live. In Jordan, the survival rate is 16 percent.

And while cervical cancer patients have a five-year survival rate of over 70 percent in countries like Mauritius and Norway, the rate in Libya is under 40 percent.

That's the sobering news from the largest cancer study ever published. It surveyed more than 25.7 million patients and reveals a huge gulf in cancer survival worldwide."

3D Mammography Improves Cancer Detection in "Dense" Breasts

"Our findings are extremely promising, showing an overall relative increase in the cancer detection rate of about 30 percent," Dr. Skaane said. "Stratifying the results on invasive cancers only, the relative increase in cancer detection was about 40 percent."

Getting Off the Couch Could Save Your Life

"Women with breast cancer who engage in physical activity, even if at moderate level, have a lower risk of death, cancer-specific or not; according to new research presented yesterday at the 2014 World Cancer Congress in Melbourne, Australia."
