Cancer Care in Small Pacific Island States

Abstract

Background: Like other LMICs, many Pacific Island countries and territories (PICTs) have fragile and overburdened health systems with which to combat an increasing burden of cancer. Additionally, a combination of small geographically dispersed populations, limited resources, isolation and frequent natural disasters make cancer control in Pacific Islands also significantly different to elsewhere in the world. No prior work has provided a stocktake of current capacity for diagnosis and treatment of cancer across the region to date. Aim: To describe the specialized health services available for cancer control in the Pacific region, and show the complexity associated with accessing cancer care for Pacific Islanders. Methods: A cross-sectional review of medical services and human resources available for cancer control was undertaken for 21 Pacific Community (SPC) member countries and territories in April-May 2018 , specifically diagnosis (pathology and radiology) and treatment (chemotherapy, radiotherapy and surgical modalities and overseas referrals for services not available on-island) by contacting individual countries and territories. Common travel routes were mapped individually for 4 PICTs; Papua New Guinea, Solomon Islands, Kiribati and Tokelau; as examples of the unique challenges faced by rural dwelling Pacific Islanders when accessing the highest level of care available in-country. Results: Capacity for cancer diagnosis and care is extremely limited in the Pacific region. The exceptions are the 2 French territories (French Polynesia and New Caledonia) and Guam where a near full complement of services for diagnosis and treatment are operational. Some pathology services are generally available in the larger PICTs, while specimens are sent to affiliated off island laboratories for the rest. Plain x-ray and ultrasound are available at 1 or more locations in all PICTs. General and gynecologic surgery is the most widespread treatment modality available. Some to full chemotherapy administered in 7 and radiotherapy in 3 (formerly 4) PICTs. Overseas referrals for medical services not available in-country are a common feature to all PICTs health systems. A need to travel long distances to access health care is a challenged faced by Pacific Islanders on outer islands and rural villages. Examples will be presented. Conclusion: Cancer control services are few and far between in the Pacific region, and PICTs will always likely rely on overseas referrals for care not available. Access barriers exist for those on outer islands and in villages, and an unknown number seek treatment late or not at all for these reasons. Governments need to invest into strengthening primary and secondary care services, making them an option that is more easily accessible to remote populations. Collaboration between transport and health sectors to look at ways to improve frequency, regulation and safety of modes of transportation to outer islands to improve current systems.
