Recent research has highlighted significant disparities in ovarian cancer survival rates within AANHPI communities, with Hawaiian and Pacific Islanders experiencing the poorest outcomes.

These disparities are critical, revealing important patterns in how ovarian cancer affects different ethnic groups and raising questions about the underlying causes.

Dr. Alice W. Lee, a researcher at California State University in Fullerton, examined these disparities in her research on ovarian cancer patients within the AANHPI population, Science Direct reports.

While Asian Americans overall have been observed to have the highest ovarian cancer survival rates among other racial groups in the U.S., Lee’s recent findings emphasize that this generalization masks significant disparities between the various ethnic subgroups.

Lee’s study, which dissected ovarian cancer survival by ethnic subgroup, reveals that while some Asian American subgroups, such as Indian and Pakistani populations, have better survival rates, others, particularly Hawaiian and Pacific Islanders, face worse outcomes.

By analyzing data on ovarian cancer cases diagnosed between 2006 and 2020, Lee’s research unveiled ethnic-specific disparities that were previously overlooked.

Hawaiian and Pacific Islanders were the only Asian subgroups to demonstrate a lower five-year survival rate than Non-Hispanic White groups, with survival rates of 44.99% and 47.9%, respectively. In contrast, Indian and Pakistani patients demonstrated the highest survival rate at 56.12%.

Data trends suggested that Native Hawaiians and Pacific Islander’s poor survival outcomes could be related to higher rates of smoking and body mass index (BMI).

However, Lee acknowledges the complexity of ovarian cancer survival. In her research, she notes that survival is not determined by a single factor but rather by a combination of many, some of which remain unidentified.

Lee’s findings align with similar studies that call for the disaggregation of Asian American health data. Aggregating health data across such a diverse population can obscure important disparities, as shown in a 2020 study examining epithelial ovarian cancer cases, which also found that Hawaiian and Pacific Islanders had the poorest outcomes.

These disparities are often attributed to a combination of factors, including differences in healthcare access, genetics and lifestyle factors. Nevertheless, disaggregating data by ethnic subgroup, as Lee has done, helps clarify these disparities and provides a more accurate picture of health outcomes.

A 2012 study on Asian American health data reinforced the dangers of aggregating health information. According to the study, many health studies group together or examine just one subgroup, neglecting the considerable diversity within this population.

To address these issues, experts recommend that future research recognizes and interprets the diversity among these groups. This ideology is echoed in Lee’s work, as she emphasizes how disaggregated health data reveal disparities among ovarian cancer cases that would otherwise remain hidden.

Dr. Lee calls for continued research to uncover all the variables that contribute to these survivable differences and to disaggregate data to more accurately represent Native Hawaiian and Pacific Islander populations.
