Socioeconomic disparities in cancer survival: Relation to stage at diagnosis, treatment, and centralization of patients to accredited hospitals, 2005-2014, Japan.

ABSTRACT:

Background

Cancer survival varies by socioeconomic status in Japan. We examined the extent to which survival disparities are explained by factors relevant to cancer control measures (promoting early-stage detection, standardizing treatment, and centralizing patients to government-accredited cancer hospitals [ACHs]).

Methods

From the Osaka Cancer Registry, patients diagnosed with solid malignant tumors during 2005-2014 and aged 15-84 years (N = 376,077) were classified into quartiles using the Area Deprivation Index (ADI). Trends in inequalities were assessed for potentially associated factors: early-stage detection, treatment modality, and utilization of ACH (for first contact/diagnosis/treatment). 3-year all-cause survival was computed by the ADI quartile.
