Her breast cancer diagnosis was grim; a second opinion saved her life

July 15, 2014 | by

At 29, Kommah McDowell was a successful young professional engaged to be married to her best friend. She worked in the financial services sector and kick-boxed to keep in shape and to relax. Then came the diagnosis of triple-negative inflammatory breast cancer, a rare and very aggressive form of breast cancer. She was told she had a 5 percent chance of living two years. Here’s her story …

breast cancer

Kommah McDowell, a breast cancer survivor, serves as a mentor for black women who recently completed breast cancer treatment and are transitioning into the follow-up stage of their care.

For seven months, McDowell had been visiting her primary care doctor every other week complaining of pain, tenderness, swelling and a lump in her right breast. She was assured it was only a benign cyst that would go away – she was too young to have cancer. Finally, at McDowell’s insistence, the “cyst” was removed. During that surgery, the doctor found cancer.

“Unbelievably, the medical staff was not familiar with the type of cancer,” McDowell said. “They just knew it was cancer and the best course of action was to remove it immediately. Fortunately, I was able to go to City of Hope for a second opinion and treatment.” » Continue Reading

Using neural stem cells to sneak up on breast cancer metastases

May 3, 2013 | by
A City of Hope researcher was awarded a grant to continue collaboration on research using neural stem cells, which naturally home to cancer cells, to deliver cancer-fighting drugs.

A City of Hope researcher has been awarded a grant to use neural stem cells, which naturally home in on cancer cells (shown here), to deliver cancer-fighting drugs.

Triple-negative breast cancer is both aggressive and tough to fight with existing therapies, a combination that often results in the disease’s spread; in fact, most deaths related to this form of cancer occur due to metastases. New City of Hope research is targeting these metastases specifically.

Building on a platform developed at City of Hope by Karen Aboody, M.D., Rachael Mooney, Ph.D., a postdoctoral CIRM Scholar and a fellow in Aboody’s laboratory, hopes to use stem cells to deliver tiny packages of chemotherapy to breast cancer-related metastases.

Aboody’s platform involves neural stem cells that naturally home in on cancer sites in the body.  These cells are modified to secrete an enzyme that activates a prodrug – a benign substance – to become a powerful cancer-killing agent locally at the tumor sites. » Continue Reading

Scientists work across disciplines to fight breast, ovarian cancers

March 10, 2013 | by

The Women’s Cancers Program at City of Hope unites scientists from across disciplines who aim to prevent cancer, seek out better treatments and help survivors live whole, healthy lives. Led by Joanne Mortimer, M.D., the program strives to bring hope and healing to women fighting cancer. Here’s a snapshot of the current research efforts:

Among the research into women’s cancers at City of Hope is a study by Susan L. Neuhausen of how gene mutations affect a woman’s risk of ovarian cancer and her response to treatment. Shown here: DNA strands.

Predicting risk for cancer

Susan L. Neuhausen, Ph.D., the Morris & Horowitz Families Professor in Cancer Etiology and Outcomes Research, has been studying women with breast and ovarian cancers since 1992 and was part of the team that discovered the BRCA1 and BRCA2 gene mutations. Now, Neuhausen and her team are collaborating with gynecologic surgeons and medical oncologists at City of Hope to investigate mutations in genes involved in the response to DNA damage.

They seek to understand how these mutations impact a woman’s risk for developing ovarian cancer and her response to treatment. Information gathered from this study will be used to develop preventive strategies and design more targeted treatments to reduce the risk of ovarian cancer recurrence.

Assessing cancer risk in underserved populations

In Hispanic women, breast cancer is the most commonly diagnosed cancer, and the leading cause of cancer death. Jeffrey N. Weitzel, M.D., director of the Division of Clinical Cancer Genetics, and a team of researchers seek to understand genetic predisposition in this population. » Continue Reading

Nanotechnology may turn stem cells into breast-cancer smart bombs

stem cell research

Karen Aboody, M.D., turns neural stem cells into targeted drugs that track down and kill cancer cells.

Triple-negative breast cancer is, in a way, the outlier in breast cancer research. Increasingly effective targeted treatments are now used against other breast cancers, but with no vulnerable gene target, no response to hormone therapy and a resistance to most available standard treatments, triple-negative breast cancer can be a monstrous mountain to overcome.

City of Hope researchers Karen Aboody, M.D., and Jacob Berlin, Ph.D., are collaborating to develop new therapies using neural stem cells and nanoparticles. Ultimately, such treatments may offer more options and improved treatments for women with triple-negative breast cancer — so-called because it isn’t fueled by the hormones estrogen or progesterone or by too many HER2 receptors.

‘My cancer diagnosis: What I wish I’d known’ – Stephanie Hosford

During three turbulent days in 2007, Stephanie Hosford, then 37, learned that she was pregnant with her long-awaited second child – and that she had triple-negative breast cancer.

Not long after the diagnosis, Stephanie also discovered that she and her husband, Grant, had been approved to adopt a little girl from China.  They proceeded with both plans to expand their family.  » Continue Reading

Super foods: A palatable way to defend against breast cancer

October 31, 2012 | by

Science is proving that a trio of popular and tasty super foods could offer an effective way to prevent breast cancer. The findings are hard evidence that some foods can work against cancer.

City of Hope’s Shiuan Chen, Ph.D., professor and chair of the Department of Cancer Biology, has studied the cancer-fighting potential of foods for decades. His early work began with mushrooms. In the years since, he’s added blueberries and pomegranates to the list.

Chen has found these foods have natural chemicals that can put the brakes on breast cancer.

Most breast cancers need estrogen to live. Breast cancer cells use the enzyme aromatase to make lots of estrogen. Chen found that mushrooms and pomegranates make compounds that block aromatase.

And blueberries may prove to be even more important. They make a chemical that can combat so-calledtriple-negative breast cancers, one of the toughest forms to treat. These tumors don’t need estrogen to grow. Worse, they remain unaffected by some of the most current and effective breast cancer drugs.

Using a concentrated extract of blueberries, Chen and his colleagues showed that triple-negative tumors could be stopped in laboratory models.

Chen recently told NBC Los Angeles about his work.

Researchers tackle cancer stem cells to counter triple-negative breast cancer

November 1, 2011 | by

Nearly one out of five breast cancer patients has triple-negative breast cancer — an aggressive type of tumor that often returns despite treatment. This cancer can defy conventional therapy, and breast cancer stem cells may be to blame, explains City of Hope’s George Somlo, M.D., F.A.C.P.  in this video.

Somlo, co-director of City of Hope’s Breast Cancer Program, says that successful, modern therapies like Herceptin target receptors found on the surface of most breast cancer cells. But triple-negative breast cancers have none of those receptors. They can resist other drug treatments, too, because their cells appear to act like cancer stem cells. Cancer stem cells can survive chemotherapy and radiation and then spread to other parts of the body.

But Somlo has joined with researchers at Stanford University to go after these stem cells. With major funding from the National Institutes of Health, the scientists are looking at triple-negative breast cancers in different ethnic groups and studying the characteristics of these cells. By understanding how the cells are different from other cancer cells and healthy breast cells, they hope to find pathways that are critical to the cells’ survival. Once they find those pathways, they can test drugs to block them.
