Abstract PO-005: Geospatial hotspot analysis of cervical cancer among Asian American Native Hawaiian Pacific Islander (AANHPI) population in Los Angeles County

Abstract

Abstract Background: Higher cervical cancer incidence rates among subgroups of Asian American Native Hawaiian Pacific Islander (AANHPI) women are often overlooked in studies that aggregate this extremely heterogeneous population. There is a need to geographically target ethnic subgroup communities with the highest needs with culturally responsive services for cancer prevention. We analyzed the distribution of cervical cancer clusters among the ethnic subgroups of AANHPI women in Los Angeles County. Methods: We included data for first primary cancer cases with any stage of cervical cancer (only malignant tumors) diagnosed from 2000 to 2018 among AANHPI from the Los Angeles County Cancer Surveillance Program. We performed hotspot analyses using the Getis-Ord GI*statistic in ArcGIS to compare the distribution of statistically significant clusters of cervical cancer cases in Los Angeles County using a fixed band. Hot and cold spots with less than 11 cases were suppressed to protect patient confidentiality. Results: Among 8,708 cases of cervical cancer, AANHPI population accounted for 1332 cases (15%). Among the AANHPI population, the three most prevalent ethnic groups were Filipino (n=364, 28%), Chinese (n=314, 24%), and Korean (n=232, 18%) Americans. The hotspots varied by ethnic subgroups and emerged in areas with high proportions of Filipino (Glendale/Carson), Chinese (Arcadia/El Monte), and Korean (Hollywood Hills) American residents, respectively. Discussion: Our findings geospatially disaggregate the cervical cancer prevalence among AANHPI population in Los Angeles County by ethnic subgroups. Specifically, the cervical cancer hotspots contextualize potential geographic- and area-level factors that affect access to preventive services for these vulnerable populations and can facilitate allocating resources for culturally responsive services to increase uptake of HPV vaccination and screening.
