Abstract

Abstract : Outcome in cancer may be improved by early diagnosis and prompt treatment. The objectives of this study were to determine the prediagnostic intervals (lag time) in childhood cancer and the factors that influence them at the University College Hospital (UCH), Ibadan. The study was prospective and observational and involved children diagnosed with cancer from July 2012 to June 2014 at UCH, Ibadan, Nigeria. A history of the illness was obtained and physical examination performed on each patient. Information obtained and analyzed included sociodemographic data, cancer diagnosis and stage, time intervals between onset of symptoms and diagnosis, and the reasons for delayed diagnosis. A total of 91 children were studied, comprising 46 males and 45 females. Their ages ranged from 1 month to 15.0 years, with a median of 4.0 years. Median parent lag time was 2.0 weeks, median health system or physician lag time 8.0 weeks, and median overall lag time 15.5 weeks. Overall lag time had a negative correlation with age of child at diagnosis, a positive correlation with the number of health facilities visited before diagnosis, and was shorter in mothers younger than 40 years of age. Lag time was significantly different among the diagnostic tumor categories, with Burkitt lymphoma having short times and retinoblastoma with long times. Delayed diagnosis of childhood cancer is a significant problem in Ibadan. Education of parents and health workers on early presentation and accurate diagnosis are recommended.
