Objectives To analyze the epidemiological aspects of primary and metastatic tumors of the central nervous system (CNS) among patients operated on by a single surgeon dedicated to neuro-oncology at Hospital Regional do Oeste, in Chapecó (Santa Catarina, Brazil), between 2013 and 2016. Methods Cross-sectional, retrospective, and observational analysis of 347 patients undergoing surgery due to intracranial tumors. The patients' data were obtained from the hospital registry, medical records, and pathology reports. Results Primary CNS tumors comprised 72.1% of the sample. There was a predominance of females (52.7%), and the mean age was 49.3 years, with a peak of incidence between the ages of 25 and 64 years. Gliomas were the most common primary brain tumors (23.7%), followed by meningiomas (17.0%). Lung cancer (15.3%), breast cancer (4.9%), and melanoma (3.5%) were, in descending order, the most frequent primary sites of metastases, which were recorded in 97 cases (27.9%). Conclusion The lack of standardization in the process of notification of tumor diseases imposes challenges in the establishment of estimates close to the real ones, preventing improvement of public health care policies to protect patients with neuro-oncological conditions. Based on the current model, regionalization of the data seems to be the best option in the management of this subgroup of patients.
Objetivo: determinar a epidemiologia e as características clínicas do melanoma cutâneo (MC) na região Oeste do estado de Santa Catarina, Brasil. Métodos: este estudo transversal e descritivo avaliou o comportamento clínico e o perfil epidemiológico do MC em pacientes de 78 municípios do Oeste do Estado de Santa Catarina, Brasil, no período de 2002 a 2016, tratados no Sistema Único de Saúde. Para a análise dos dados foi utilizado o teste do Qui-quadrado. Para elaborar as curvas de sobrevida, foi considerado um período de 10 anos (teste Log Rank). Resultados: dados de 1.146 pacientes foram avaliados, e houve uma média de 20 casos/100.000 habitantes/ano. Encontravam-se nos estágios I e II 63,5% dos pacientes. A sobrevida global em 10 anos de acompanhamento foi de 89%(IC95% 87,7% - 91,5%). Pacientes do sexo feminino apresentaram maior sobrevida (94,5%; IC95% 92,7% - 96,4% vs. 82,6%; IC95% 78,9% - 86,3%; p < 0,001) e variáveis de melhor prognóstico. Conclusões: o Oeste do estado de Santa Catarina apresentou uma alta prevalência de MC. As características clínicas e epidemiológicas encontradas concordam com as descritas nas populações que residem em regiões geográficas equivalentes; mas diferem de outras regiões do Brasil. Essas diferenças, associadas à organização do sistema público de saúde de referência e contra-referência, podem explicar aos resultados de sobrevida encontrados.
