Gastric neoplasia is a heterogeneous and multifactorial disease and its incidence and mortality vary widely based on geographic location. Approximately 60% of the diagnoses of patients from occidental countries were made on the stages III and IV. The best treatment still is to realize a surgical procedure. AIM: Identify the epidemiological aspects of the patients diagnosed with T4b gastric adenocarcinoma. METHODS: The study was observational, transversal and retrospective; it was also based on secondary sources from patients diagnosed with T4b gastric adenocarcinoma, through pathologic stages. A total of 815 charts were analyzed and 27 patients studied. The variables were: demographic aspects, main symptoms, risk factors, access to health system, surgical aspects, morbidity, mortality and survival. RESULTS: Were included 22 men (81,5%) and five woman (18,5%), in the age group between 38 and 87 years old - median age of 58. The time, in months, to access the health system varied from one to 120, average of 12,5 months. The most prevalent signs and symptoms were: weight loss 23 (85,2%), epigastric pain 22 (81,5%), vomit 16 (59,3%) and gastric fullness 12 (44,4%). The frequency of the affected adjacent body structures was: pancreas 8 (29,6%), liver 7 (25,9%), transverse colon 6 (22,2%), small intestine 6 (22,2%), mesocolon 3 (11,1%), spleen 1 (3,7%) and gallbladder 1 (3,7%). Postoperative morbidity occurred in 51, 85% of the patients. There were a significative association between surgical mortality and the occurrence of fistula/ dehiscence, septic shock and bleeding. The survival rate after six months was 63,27%. CONCLUSION: The mean time between onset of symptoms and access to specialized health services was high. More than half of the patients had postoperative morbidities. Patients who had fistula / dehiscence, bleeding and septic shock were significantly associated with surgical mortality. The survival rate after six months was 63.27%.

Imunoexpressão da proteína PTEN em amostras de carcinoma epidermoide bucal e sua correlação com características clínico-patológicas e sobrevida

Oral Squamous Cell Carcinoma (OSCC) is the most common malignant neoplastic that affects the oral cavity, accounting for 90% of all cases diagnosed in this anatomic site. Despite the recent advances in the treatment, the survival rate varies from 30 to 50%. Molecular mechanisms which elucidates the agressive behaviour of these lesions help to identify new chemotherapeutics that might be used in the treatment in order to improve the survival rates. The aim of this study was investigating the imunoexpression of PTEN protein through the immunohistochemical technique (IHC) in CEB samples and relate them with clinicopathological features, histological grades and survival and in addition, evaluate the presence of allelic deletion through the Fluorescent In Situ Hybridization technique (FISH). Our results showed that a total from 119 cases of CEB, 31 cases were negative to expression of protein PTEN and 88 cases were positive for PTEN, from which 15 (17,05%) were well differentiated, 43 (48,86%) moderately differentiated and 30 (34,09%) were poorly differentiated. Considering the clinicophatological features, there were not statistically significant correlations with the IHC expression of PTEN. Regarding the survival rates, it was observed that patients presenting lymph node infiltration (N) = 2 or 3 has 4 times greater risk of dying than those presenting N = 0 or 1. Finally, there was a significant association between expression by IHC negative and the result of FISH technique regarding the deletion, and between the positive PTEN expression and the non-deleted result of FISH technique.

Perfil sociodemográfico, clínico e de sobrevida de pacientes adultos metastáticos
(Universidade Federal do Rio Grande do Sul, 2023) ESTUMANO, Vanessa Kelly Cardoso; SAGICA, Taís dos Passos; ALBUQUERQUE, Gisela Pereira Xavier; COSTA, Marta Solange Camarinha Ramos; PEREIRA, Odenilce Vieira; MELO, Edjane Marcia Linhares; SILVA, Sílvio Éder Dias da; RAMOS, Aline Maria Pereira Cruz
Objective: To characterize the sociodemographic, clinical and survival profile of adult metastatic patients.Method: Retrospective cross-sectional study, with secondary data from an oncology care unit, analyzed using logistic regression, Chi-Square test and Fisher’s exact test, Kaplan-Meier and Log-Rank tests.Results: From the 678 patients, male gender, mean age 59.54 years old and low education level prevailed. The mean time between diagnosis and initiation of treatment was 89.50 days (± 58.87). Increased risk of primary cancer in the digestive tract (OR 1.42). Prevalence of adenocarcinoma (OR 1.53) and metastasis to bone (OR 2.59), lymph nodes (OR 1.75), liver and peritoneum (OR 1.42). The mean overall survival was 4.16 months and a median of 3.0 months.Conclusion: The main primary site was the digestive system, and the identification of metastases was predominantly unifocal liver in both genders. Overall patient survival was reduced by cancer progression.

Sobrevivência e dispersão de células da fração mononuclear da medula óssea transplantadas heterologamente no estriado após isquemia experimental
(Universidade Federal do Pará, 2015-02-27) CARDOSO, Marcelo Marques; SAUNIER, Ghislain; http://lattes.cnpq.br/6254015055212071; LEAL, Walace Gomes; http://lattes.cnpq.br/2085871005197072
The studies show the promising potential of bone marrow mononuclear cells (BMMC) for the treatment of stroke models. It is known that the BMMC are sensitive to environmental changes, like those induced by ischemia, such as events associated with inflammation. However, little is known about the biodistribution and survival of these cells in the post-injury nerve tissue. Aims to investigate whether the survival and spread of BMMC are influenced by the inflammatory response after striatum stroke. Heterologous transplantation (5x105 BMMC) in the striatum of rats clustered among untreated controls (CNT) and sham (SHM) and treated (STBC) perfused at 1, 3, 7 and 28 days. BMMC were impregnated with Qdot nanocrystals for identification by fluorescence microscopy in the host tissue. Staining for cresyl violet, and basic immunohistochemistry (IBA1 and ED1) were applied for histopathological analysis of tissue by light microscopy. Neurobehavioral tests (adhesive removal test and cylinder test) were performed to assess the response of groups for interventions. The results show the effectiveness of the experimental model of ischemic induction to reproduce the injury in the dorsolateral striatum. The cell infiltrate in the CNT group shows the inflammatory response, later confirmed by immunohistochemistry for ED1 and IBA1; the cellular infiltrate in STBM group, shows the BMMC of stay in all studied survival. The loss profile for death of BMMC transplanted into the injury site is similar between STBM and SHM groups, however, shows that inflammatory response of the receptor causes more decay of cell amount in STBM group. More refined or automated cell infusion procedures can improve the sensitivity of behavioral tests to discriminate the evolution between groups. To summarize the change of post-ischemic microenvironment creates conditions that determine the distribution and survival of BMMC. Other immunohistochemical procedures may point to the results presented as microglial profile and the degree of the immunomodulation study of the dynamics of inflammatory cytokines produced.
