ABSTRACT Objective To understand the feasibility of FGFR3 tests in the Brazilian public health context, and to sample the mutational burden of this receptor in high-grade muscle invasive bladder cancer. Methods A total of 31 patients with high-grade muscle-invasive bladder cancer were included in the present study. Either transurethral resection of bladder tumor or radical cystectomy specimens were analyzed. Formalin-fixed paraffin-embedded tissue blocks were sectioned, hematoxylin and eosin stained, and histologic sections were reviewed. Total RNA was extracted using the RNeasy DSP formalin-fixed paraffin-embedded kit. Qualitative results were displayed in Rotor-Gene AssayManager software. Results Six patients were excluded. From the samples analyzed, four (16.7%) were considered inadequate and could not have their RNA extracted. Two patients presented FGFR3 mutations, accounting for 9.5% of material available for adequate analysis. The two mutations detected included a Y373C mutation in a male patient and a S249C mutation in a female patient. Conclusion FGFR3 mutations could be analyzed in 84% of our cohort and occurred in 9.5% of patients with high-grade muscle invasive bladder cancer in this Brazilian population. FGFR3 gene mutations are targets for therapeutic drugs in muscle-invasive bladder cancer. For this reason, know the frequency of these mutations can have a significant impact on public health policies and costs provisioning.

SUMMARY INTRODUCTION: Drug interaction is an important cause of global morbidity. It is of particular importance in cancer patients since they are often in use of polypharmacy, related to interactions between the drugs and the chemotherapeutics used. OBJECTIVE: To evaluate the drug interaction between chemotherapy and other drugs in cancer patients. METHODS: a cross-sectional study carried out in the outpatient oncology department of a public tertiary hospital. Two hundred thirty-five patients were included, and the drugs they were using were identified. Using the MedScape and Epocrates database, we evaluated the interactions between medications and chemotherapy by defining their frequency and dividing their severity from interaction into mild, close monitoring necessity and severe. RESULTS: 161 patients had some drug interaction. We identified 9 types of mild interactions, 23 types of interactions with close monitoring necessity, and 2 types of serious interactions. The most frequent interactions were between fluorouracil and leucovorin (32 cases) and cyclophosphamide and doxorubicin (19 cases). Serious interactions were between aspirin and pemetrexed; and leucovorin and Bactrim. CONCLUSION: In the present study, drug interactions were frequent, including serious interactions with a potential increase in morbidity and mortality. Thus, it is necessary for oncologists to draw up a therapeutic plan considering potential interactions between prescribed chemotherapy and current medications in use by patients.

RESUMO INTRODUÇÃO: Interação medicamentosa é uma importante causa de morbidade mundial. Apresenta especial importância em pacientes oncológicos, pois esses frequentemente estão em uso de polifarmácia, podendo haver interações entre os medicamentos e os quimioterápicos utilizados. OBJETIVO: Avaliar a interação medicamentosa entre a quimioterapia e outros medicamentos em pacientes oncológicos. MÉTODOS: Estudo transversal realizado em serviço ambulatorial de oncologia de um hospital público terciário. Foram incluídos 235 pacientes, identificando-se quais medicamentos eram utilizados por eles. Por meio do auxílio do banco de dados do MedScape e Epocrates, avaliaram-se as interações entre as medicações e os quimioterápicos, definindo sua frequência e dividindo sua gravidade da interação em leve, monitorização próxima e grave. RESULTADOS: Do total estudado, 161 pacientes apresentavam alguma interação medicamentosa, sendo nove tipos de interações leves, 23 tipos de interações com necessidade de monitorização próxima e dois tipos de interações graves. As interações mais frequentes foram entre fluoracil e leucovorin (32 casos) e ciclofosfamida e doxorrubicina (19 casos). As interações sérias foram entre aspirina e pemetrexed; e leucovorim e bactrim. CONCLUSÃO: No presente trabalho, interações medicamentosas foram frequentes, incluindo interações graves com potencial aumento de morbimortalidade. Assim, faz-se necessário que oncologistas tracem um plano terapêutico levando em consideração as possíveis interações medicamentosas entre a quimioterapia prescrita e demais medicações em uso pelos pacientes.

SUMMARY INTRODUCTION Structural disparities between different Brazilian regions in public health system cause patients to migrate in search of better conditions to treat their diseases. Besides patient's discomfort, there is a concentration of care in large centres, causing overload to current capacity. OBJECTIVE To evaluate migratory flow and associated factors in a reference service in oncology. METHODS Cross-sectional study conducted at a referral oncology service in Great ABC region of São Paulo. Patients were interviewed, and clinical and demographic data collected. RESULTS Between March-July 2016, 217 patients were included. Analysis showed a divergence between the postal code registered in the medical record and that recorded during the interview in approximately 10% of cases. Of these, 42.9% were residents of other states. Search for treatment motivated most patients to seek service outside their city. CONCLUSION Results reflect the informal search for medical care outside the home area. Besides the direct impact on patients' quality of life, migratory flow has an economic-social impact because these patients place a burden and impose costs on services of cities where they do not perform their responsibilities as citizens. Confirmation of the existence of a significant migratory flow demonstrates the need to discuss restructuring public health policies.

RESUMO INTRODUÇÃO As disparidades estruturais entre diferentes regiões brasileiras no sistema de saúde pública fazem com que os pacientes migrem em busca de melhores condições para tratar suas doenças. Além do desconforto do paciente, há uma concentração de cuidados em grandes centros, causando sobrecarga da capacidade atual. OBJETIVO Avaliar o fluxo migratório e fatores associados em um serviço de referência em oncologia. MÉTODOS Estudo transversal realizado em um serviço de oncologia de referência na região do Grande ABC, em São Paulo. Os pacientes foram entrevistados e dados clínicos e demográficos coletados. RESULTADOS Entre março e julho de 2016 foram incluídos 217 pacientes. A análise mostrou uma divergência entre o código de endereçamento postal registrado no prontuário médico e o registrado durante a entrevista em aproximadamente 10% dos casos. Desses, 42,9% eram residentes de outros estados. A busca de tratamento motivou a maioria dos pacientes a buscar serviços fora de sua cidade. CONCLUSÃO Os resultados refletem a busca informal de cuidados médicos fora da área de residência. Além do impacto direto na qualidade de vida dos pacientes, o fluxo migratório tem um impacto econômico-social porque esses pacientes colocam um fardo e impõem custos aos serviços das cidades onde não executam suas responsabilidades como cidadãos. A confirmação da existência de um fluxo migratório significativo demonstra a necessidade de discutir a reestruturação das políticas de saúde pública.
