Incidence and disease prevalence for hematologic neoplasms in Poland (2009–2015) as determined on the analysis of the National Health Fund data used in the project ‘Maps of healthcare needs — database of systemic and implementation analyses’
Abstract
In Poland, there is a shortage of statistical data regarding neoplasia of hematopoietic system. There is an unmet demand for epidemiological data concerning such cancers stemming from both scientific and health care management reasons. As all medical services for patients with these disorders are reported to the National Health Fund (NFZ) the aim of this study was to use NFZ data for determining incidence and prevalence of neoplasia of myelopoietic part of hematopoietic system in Poland, as well as defining the overall survival (OS) in affected patients. This work was performed under the project ‘Map of healthcare needs — database of systemic and implementation analyses’ co-funded by the European Union Social Fund from the Operational Programme for the Development of Knowledge and Education. The incidence rate in 2014 for acute myeloid leukaemia (AML) was 4.1/100,000 whilst the registered disease prevalence rate was 10.9/100,000. The median OS during 2009–2015 for AML — reported patients was 6 months and the 3- and 5-year OS was estimated as respectively being 26.5% and 23.4%. For chronic myelogenous leukemia (CML) the incidence and disease prevalence rates were 1.0/100,000 and 7.2/100,000 respectively, and those for Philadelphia-negative myeloproliferative neoplasms (MPN Ph–) were 8.9/100,000 and 55.9/100,000 respectively, whilst those for myelodysplastic syndromes (MDS) were 3.8/100,000 and 11.5/100,000 respectively. In patients reported as having CML, the 3- and 5-year OS was 76.2% and 68.1% respectively. In patients reported as having MPN Ph(–), the 3- and 5-year OS was 86.6% and 78.6% respectively. The median OS for patients reported as having MDS was 30 months and the probability of patients achieving 3- and 5-year OS was 45.8% and 36.1% respectively. Data reported to the NFZ for reimbursement of medical services provided seem to be the most reliable concerning such large patient population. Yet, there are still prone to errors arising from the mis-coding of cancers and to limited compatibility of the ICD-10th Revision (International Classification of Diseases) to current World Health Organization classification, Nevertheless, our data are similar to the European and USA registers regarding AML and MDS. However, in the case of MPNs (CML excluding) they require further verification.
