P2-283 Breast cancer data quality at the population-based cancer registry of Sao Paulo: implications for public health surveillance and planning

Abstract

11e15 years (51.0%), followed by 16 years and older (31.1%). The most common hearing complaint was hearing loss (27.4%), followed by otalgy (17.9%) and tinnitus (16.0%). The occurrence of suppurative otitis media was related by 12.3% of patients and 18.9% presented tympanic membrane perforation at the time of hearing evaluation. Patients with hearing loss had higher prevalence of hearing complaints than those with normal hearing: otorrhoea (92.9%37.1%; p<0.001), tinnitus (76.5%323,5%; p<0.001), otalgy (68.4%331.6%; p¼0.001) and sensation of fullness in the ear (61.5%338.5%; p¼0.039). There was no difference according to dizziness (36.4%363.6%; p¼0.970). Conclusion It is extremely important to precociously detect, evaluate and observe any hearing complaints that these patients may present. These are important signs that if detected and treated early, can avoid serious consequences like hearing loss. Cancer affects millions of people each year worldwide and represents a major challenge for healthcare systems. Information based on populational data, such as Cancer Registries, are essential to endorse health planning and provision of cancer care services. This paper aims to present a data quality evaluation of breast cancer incidence data from the Population Based Cancer Registry of the Municipality of São Paulo, Brazil. The study included 46 311 new breast cancer cases recorded during a two 5-year periods (1997e2001 and 2002e2006). Data analysis was focused on variables such as: date and age at diagnosis, clinical stage, topographic distribution and tumour morphology. For women aged between 40 and 69 years, the most common diagnosis was the malignant neoplasm of breast, unspecified (ICD-10 C50.9), (87,6% of all cases), which does not specify clearly the topography and extent of disease. Problems of information completeness for important variables such as clinical and pathological staging were identified on time-series analysis. Hence, data quality of cancer registries are crucial for breast cancer survival analysis as well as for planning cancer control policies, enhancements on data collection are required. P2-283
