Urachal tumor is extremely rare, since it is responsible for about 0.01% of all neoplasms already repeated in the history of clinical oncology, with the adenocarcinoma subtype being the most prevalent. Thus, the present work aims to report a case of a 55-year-old patient diagnosed with urachal tumor, relating the clinical presentation of the case according to current literary data. It was possible to show that such a diagnosis, as well as the institution of a standard treatment, is still a clinical challenge in modern medical practice.

6632 Background: Brazilian data for cancer survival are scarce. Therefore, we aimed to describe the 5-year overall survival (OS) of individuals with public and private insurance from Rio Grande do Sul/RS (Brazil) diagnosed with the 17 most incident tumors in the country. Methods: Data from 19 of the 27 hospital-based cancer registries from RS were integrated with the Brazilian Information System data. Individuals with confirmed cancer diagnoses between 2005-2017 were included. Passive follow-up time was calculated as the difference between diagnosis and death (from any cause) or censure date. Survival was estimated by Kaplan-Meier method. Comparison between the survival of individuals assisted by public or private insurance was evaluated using hazard ratios (HR) estimated by multivariate Frailty and Cox regression models with adjustments for age, sex, and economic status. Results: 5-year OS was higher for patients with private health insurance for 13 of the 17 cancers studied. Conclusions: The survival trends among cancer patients assisted by public and private health insurance systems reveal vast differences that may be likely attributable to differences in access to early diagnosis and optimum treatment. We hope our results will help government officials understand that ongoing cancer survival surveillance is an indispensable source of information and a key policy tool for public health decisions.

Pancreatic neoplasm is represented by the subtype Adenocarcinoma in 90% to 95% of cases, characterized by the high lethality rate of its presentations; however, cases of progression in the brain site are manifested in only 0.1% to 0.3% of all the cases. The present study aims to report a rare case of a patient undergoing treatment for pancreatic cancer, which had a median overall survival significantly higher than the median time related to such neoplasm, and during the final evolution of the disease progression, an unusual associated with symptomatic brain metastatic activity, was evidenced, thus we correlated the current medical literary data to the events presented by the reported patient. Thus, the reported case becomes of extreme clinical relevance for the study of modern clinical oncology.

Inflammatory myofibroblastic tumor (IMT), a benign and rare neoplasm, of mesenchymal origin, pseudoarcomatous, is responsible for about 0.7% of all neoplastic presentations in the pulmonary region, being the most frequent cause of pulmonary nodules in pediatric patients, approximately 50% of the presentations. Thus, the present study aims to report a rare case of IMT in the lung site in a 31-year-old patient undergoing treatment for breast cancer, according to a literary review, relating the data according to the clinical presentation. Due to scarce documentation in the medical literature, no cases were found similar to the one described in relation to the reported oncological primary condition of the patient, making the present case a clinical challenge in modern medical practice.

Os Gliomas são os tumores cerebrais mais prevalentes e representam 33% de todos os casos de tumores cerebrais já descritos, são diferenciados conforme localização, histologia, genética e agressividade. Os gliomas de alto grau possuem um potencial de agressividade elevado e prognóstico extremamente reservado, sendo as histologias raras e atípicas ainda mais agressivas e sombrias. O presente trabalho, visa relatar uma série de casos acerca dos tumores cerebrais mais prevalentes, designados gliomas, em especial os relacionados as apresentações de alto grau, levando em considerações a apresentação clínica, fisiopatologia, métodos diagnósticos e tratamentos relacionados ao tema abordado.
