A tale of two trials

Marina M.

Marina Moraitis, diagnosed with breast cancer in 2010, has a collection of “bling”—medals she’s won from running road races.  Her collection includes a dog tag from the 2017 Army Run and a medal from the 2012 Ottawa Race Weekend Half-Marathon. There’s one medal however, for a cause very close to her heart.  It’s from the 2010 5km Run for the Cure, which she trained for while undergoing chemotherapy treatment.

The results of Marina’s lumpectomy showed she had infiltrating ductile carcinoma, high grade, stage 2.  She had the BRCA1 gene mutation. Because she was at high risk of her cancer spreading, she had a double mastectomy followed by an oophorectomy to remove her ovaries.

During her treatment Marina joined two clinical trials run through The Ottawa Hospital.  As part of the first trial, she ran three times a week on a treadmill.

“The idea was to see if exercise helps cancer patients during chemo. It was proven as extremely beneficial,” said Marina. “It not only kept me in shape during my treatment, it also helped me focus on training for the 5km Run for the Cure—my goal at the end of the treatment.”

Led by The Ottawa Hospital’s own Dr. Roanne Segal, the treadmill-study results showed that patients with breast cancer who did an hour of cardiovascular exercise three times a week felt the best—Marina fit into that category.

The second trial was Dr. Barb Collins’ that looked at the effects of chemotherapy on a patient’s brain.

Cancer patients have long claimed that chemotherapy was affecting the way they think. It was like they were in a fog, not thinking clearly—an unproven condition dubbed chemo-fog.

“The Ottawa Hospital was key in bringing me back to living life to the fullest.”


The Ottawa Hospital led the way in being one of the first in the world to do a pre/post study of the effects of chemotherapy on the brain and since then, it has become a huge area of research for different kinds of cancer treatment.

Dr. Collins and her colleagues designed a clinical trial to look at patients before, during, and after chemotherapy. Twenty trial participants underwent magnetic resonance imaging (MRI) studies where brain activity was observed while they responded to cognitive questions. 

“In the women who received chemotherapy, you could see differences in the patterns of brain activation in the MRI even when they performed perfectly normally on the test. In simplistic terms, the brain is working harder,” said Dr. Collins. “As a result of studies like this one, championed at The Ottawa Hospital, chemo-fog is now taken more seriously.” 

Staff at the Breast Health Centre introduced Marina to the support group Breast Cancer Action where she met several other breast cancer survivors. Relationships began to blossom and the women often went for coffee after their exercise class, became close friends, and formed a book club which continues to meet once a month.

Marina felt very supported by the programs and staff at The Ottawa Hospital and was inspired to give back, to help future patients have a better chance of survival.

“Without the hospital I would not have this sisterhood today, which is so important to me. I owe so much to The Ottawa Hospital... participating in the clinical trials was my small way of helping future patients through research and treatments and saying thank you. The support I received was immeasurable, psychologically, physically, and emotionally.”

The Ottawa Hospital is raising funds for cancer research. Your ongoing support is needed to purchase equipment and fund research. Innovative cancer research takes more than the best minds – our researchers need the proper tools to do their vital work.
