BACKGROUND: Cancer is a leading cause of death in the world and the fourth leading cause in Malaysia. A widening disparity in cancer burden has emerged between high and low-middle income countries. A similar disparity due to differential access to cancer care between affluent and deprived groups is likely to exist within developing country too. We assess this inequality by estimating the number of deaths due to cancer that would be avoidable if all patients had access to the best available care in Malaysia, a high middle income country.
METHODS: The number of avoidable deaths is the difference between the number of deaths estimated by GLOBOCAN12 for Malaysia (which is consistent with published estimates on cancer survival), and the expected number of deaths if all patients with Breast Cancer (BC) had experienced the age-ethnic-stage specific survival outcomes observed in a leading private cancer centre in Malaysia. Data on age-ethnic-stage composition of the general BC population were from local cancer registry and public hospitals providing safety net cancer services.
FINDINGS: Of the 2312 excess deaths due to BC, 2048 (88%) were avoidable. Of these avoidable deaths, 1167 (57%) were attributable to late stage presentation while 881 (43%) were due to lack of access to optimal treatment. Sensitivity analyses however show that the 88% avoidable deaths may be as low as 50%, taking into account differences in socio-economic status, over-diagnosis and lack of very long term survival data.
INTERPRETATION: The huge number of avoidable deaths highlights the high cancer mortality rate among the deprived and the vast disparity in access to cancer care between the rich and poor within Malaysia, which mirrors the global cancer divide between rich and poor countries.
Cancer care system that deliver such disastrous and inequitable outcomes is clearly under-performing. It is in urgent need of reform.
