Underserved Pacific Islanders With Locally Advanced Cervical Cancer Receive Higher Rates of Standard-of-Care Radiation Treatment Through the Pacific Island Health Care Project and Military Health System Compared to the Average U.S. Population.

Brachytherapy, with external beam radiation, increases survival in the treatment of locally advanced cervical cancer (LACC). In 2016, Robin et al. reported only 44% of patients received standard-of-care (SOC) brachytherapy in the USA. The Pacific Island Health Care Project has provided humanitarian medical care to women from the U.S. Associated Pacific Islands (USAPI) for three decades at Tripler Army Medical Center (TAMC), a military health care system (MHS) facility. We evaluated whether this underserved and understudied patient population received SOC treatment for LACC at TAMC. The TAMC tumor registry was searched for all cervical cancer cases from 1997 to 2019. Subjects were excluded if they did not have stage IB2-IVA disease and were not from USAPI. The primary outcome was the overall utilization of brachytherapy, and statistical analysis was performed using the chi-square test. We identified 214 women with cervical cancer treated at TAMC, of which 67 met the study criteria. Ninety-two percent had squamous cell carcinoma on histology. Of the patients identified, 48 (71.6%, P < .001) were treated with brachytherapy. Fifteen (22.4%) patients received external radiation alone, and four (6.0%) received chemoradiation without brachytherapy. A post-hoc power analysis was conducted with a power of 91.3%. Women with cervical cancer from USAPI in the PIHCP program treated at TAMC received significantly higher rates of SOC radiation treatment than the U.S. population on average. This highlights the ability of PIHCP, through the MHS, to deliver SOC treatment for cervical cancer to an otherwise underserved patient population.
