SurvivorNet Fact Checking and Medical Review Standards:  

The SurvivorNet News Team creates high quality medical information that complies with our industry leading standards for factual accuracy and sourcing from leading experts at academic medical institutions. Every news article is thoroughly fact-checked by our physician collaborators. We vet each piece of work for factual integrity, impartiality, and clearly label any professional conflicts.

All SurvivorNet articles adhere to the following standards:

  1. All studies and research papers cited are from reputable academic medical institutions or peer-reviewed journals.
  2. When we use data, statistics, or quotes these references link to the original source.
  3. All content related to new treatments, drugs, procedures, and so on must clearly describe availability, side effects, treatment target (such as triple negative breast cancer)
  4. All medical information on SurvivorNet is sourced from respected medical professionals with verified medical credentials and links are provided to these sources.
  5. We strive to give the reader relevant background information and include, clearly-sourced contextual health information in all articles. Readers are clearly alerted to any conflicts of interest from a medical source or the authors of a cited study.

Disparities in Cancer Research

  • Early research on ovarian cancer didn’t include cell and tissue samples from minority women
  • One new initiative is collecting tumor and blood samples from Black women to create more diverse ovarian cancer models
  • The goal is to understand how this and other cancers act differently in Black women, and work to improve their outcomes
 
Although white women are more likely to get ovarian cancer, Black women don’t survive as long with the disease. Socioeconomic factors and access to health care may play roles in this disparity, but it’s been difficult for researchers to know for sure, given the limited number of studies that have been conducted in minority populations. To better understand how this disease uniquely affects women of different races, and improve the care doctors deliver to women of color, scientists are now trying to gather more ethnically diverse data.

"One really exciting initiative that we are very passionate about is called the Human Cancer Models Initiative, or HCMI, that is led by the National Cancer Institute (NCI)," says Dr. Stefanie Avril, gynecologic pathologist at Case Western Reserve University in Cleveland. "Our laboratory is one of four centers across the U.S. that’s participating in this initiative and contributing tumor samples and specimens."

What is the HCMI?

Many of the cancer cell lines that researchers use to study ovarian cancer were gathered many years ago, and they didn’t include diverse racial and ethnic groups. The HCMI is an international collaboration focused on collecting data and developing new cancer models that include people of all ethnic backgrounds. "The goal of the Human Cancer Models Initiative is to create new generations of cancer models that better represent the diversity of our cancer patients," says Dr. Avril.

These models and data will allow the research community to better study how ovarian cancer develops and progresses in women of different races. Using new techniques to grow cells, scientists can make models that better resemble the tissue architecture and complexity of human tumors, which will hopefully lead to more individualized treatments for minority women.

More Inclusive Research

"A lot of the current cancer models and cancer cell lines that are commercially available to researchers have been derived from white or European-American women," says Dr. Avril. "And a lot of cancer patients from racial or ethnic minorities are largely underrepresented in the research models that we have to study their diseases. We know that there are differences."

Dr. Avril and her team are collecting tumor and normal tissue and blood samples from Black women with gynecologic cancers, and in particular, ovarian cancer, to improve their outcomes. "Ultimately this will lead to creating better models and more diverse models that really reflect all of the cancer patients we are seeing in our community," she adds.

Cancer Disparities

Her work is part of a larger effort at the Case Comprehensive Cancer Center that's looking at cancer disparities. That includes cancers that occur in higher numbers, or that have a higher mortality rate in certain populations, specifically racial or ethnic minorities.

Ensuring that cancer patients from different backgrounds are equally and adequately represented in research studies is paramount in delivering the highest quality care. By understanding how ovarian cancer differs in women of different races, scientists can eventually develop more individualized treatment options that will hopefully work more effectively in specific populations.

Though it may take time to see the results, the work that’s being done today in labs like Dr. Avril’s could have long-term implications. "What we always explain to the women who are excited to participate in our research is that, while it will not benefit them directly in their care, this research will benefit women in the future," says Dr. Avril. "It will help us better understand how some of these cancers act differently in Black versus white women."
