Due to the difficulty of follow-up for long periods, information about the survival rates of malignant salivary gland tumors is deficient in the global scientific literature. This study was aimed at investigating the epidemiological profile and prognostic factors that might affect survival in patients with primary malignant salivary gland tumors in Brazil. Patients were investigated regarding histopathological subtypes, age, gender, anatomic localization, smoking and alcohol intake, tumor size, clinical stage, histological grade, recurrence, metastasis, and treatment on clinicopathological outcomes. Survival curves were generated using the Kaplan-Meier method, and both univariate and multivariate analyses were performed using the log rank test and Cox regression, respectively. A total of 63 cases were analyzed, females beingslightly predominant (50.8%), with ages ranging from 13 to 87 years. The most common diagnosis was adenoid cystic carcinoma and the most affected anatomical location was the parotid. Tumors were predominantly classified as stage I and high-grade at the diagnosis. The 5- and 10-year overall survival rates were 84.6% and 74.7%, respectively. Disease-free survival (DFS) rates were 71.6% (5 years) and 56.6% (10 years). Univariate analysis showed significant effects of tumor size and clinical stage on the DFS (P < 0.0001 for both)...

Oral squamous cell carcinoma (OSCC) accounts for more than 95% of all malignant neoplasms in the oral cavity. Although several studies have shown the epidemiology of this cancer in Brazil, there do not seem to be any studies that describe the prognostic factors related to OSCC in the Amazon region. Therefore, the aim of this study was to determine the survival rate and prognostic significance of different factors in patients from this region affected by OSCC. Data from 85 patients with histologically confirmed squamous cell carcinoma of the tongue and floor of the mouth identified from the Ofir Loyola Hospital archives were collected and analyzed using univariate (log-rank test) and multivariate (Cox proportional hazard model) tests. The overall 5-year survival rate was found to be 27%. Univariate analysis showed that the 5-year survival rate was significantly higher for younger (<= 45 y) female patients, patients with T1-2 tumors and clinically clear neck nodes (N0), patients with early stage cancers (AJCC stage I-II), and patients treated with surgical procedures. However, multivariate analysis showed that the 5-year survival rate was significantly higher only in the younger patients and those who underwent surgical treatment. The age of the patient at the moment of diagnosis and treatment with surgical procedures were the only independent prognostic factors that affected the 5-year survival rate of the patients in this region.

Hantavirus pulmonary syndrome (HPS) was described for the first time in Brazil in 1993 and has occurred endemically throughout the country. This study analysed clinical and laboratory aspects as well as death-related factors for HPS cases in Brazil from 1993 to 2006. The investigation comprised a descriptive and exploratory study of the history of cases as well as an analytical retrospective cohort survey to identify prognostic factors for death due to HPS. A total of 855 Brazilian HPS cases were assessed. The majority of cases occurred during spring (33.5%) and winter (27.6%), mainly among young male adults working in rural areas. The global case fatality rate was 39.3%. The mean interval between the onset of symptoms and hospitalisation was 4 days and that between hospitalisation and death was 1 day. In the multiple regression analysis, adult respiratory distress syndrome and mechanical respiratory support were associated with risk of death; when these two variables were excluded from the model, dyspnoea and haemoconcentration were associated with a higher risk of death.

A extensão anatômica do tumor é o fator mais importante na avaliação do prognóstico e planejamento do tratamento dos carcinomas epidermóides da cabeça e do pescoço. Além do TNM, outros parâmetros relacionados ao paciente e ao tumor auxiliam na avaliação do prognóstico. Este estudo tem por objetivo identificar fatores prognósticos demográficos, clínicos, tumorais e histopatológicos, associados à sobrevida e resposta ao tratamento no carcinoma da orofaringe. Trata-se de uma análise de 361 pacientes, submetidos à radioterapia exclusiva ou associada à quimioterapia, de 1990 a 2001, no Hospital A. C. Camargo (São Paulo) e Hospital Erasto Gaertner (Curitiba, Paraná). Entre as variáveis estudadas, encontra-se a gravidade dos sintomas, avaliada conforme o modelo de Piccirillo e Pugliano. Foram analisados os sistemas de estadiamento de Berg, TANIS 3, TANIS 4, Hart, Kiricuta e Hall, que são modificações do TNM feitas a partir do reagrupando das categorias T e N, com a finalidade de melhorar a avaliação do prognóstico. A análise estatística utilizou o método de Kaplan-Meier e o modelo de riscos proporcionais de Cox. Os principais resultados foram que a maioria dos tumores era da tonsila (47%) ou base da língua (28%)...

O avanço tecnológico nas unidades de terapia intensiva pediátricas (UTIPs) tornou-as aptas ao atendimento de casos de alta complexidade e elevado custo. Porém, a tecnologia disponível nem sempre tem conseguido melhorar a qualidade de atendimento aos pacientes e a própria capacidade de prolongar o tempo de vida torna-se um instrumento que potencializa a dor e o sofrimento. Sendo assim, tornou-se necessário caracterizar o estágio de gravidade da doença, que reflete a magnitude das comorbidades e distúrbios fisiológicos, no momento da internação. Esse procedimento pode ser realizado através dos escores prognósticos de mortalidade que quantificam a gravidade da doença, estimando a probabilidade de óbito de acordo com seu estágio clínico. Atualmente os escores prognósticos fazem parte das metodologias de controle de qualidade e de pesquisa. O Pediatric Risk of Mortality escore (PRISM) é um dos escores mais utilizados na unidade de terapia intensiva pediátrica (UTIP). O objetivo desse estudo foi avaliar a utilização do PRISM quanto a sua capacidade de discriminação entre sobreviventes e não-sobreviventes e determinar os fatores de prognóstico para óbito em uma UTIP terciária. Foi realizado um estudo retrospectivo na UTIP do Instituto da Criança do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo...

Introdução: A lombalgia gera altos custos, em todo o mundo, com tratamentos e perda de produtividade. Embora hoje existam vários tratamentos para lombalgia, não ocorrem estudos demonstrando a superioridade de um programa específico de reabilitação e o número de pacientes que recidiva da dor é alto, sobrecarregando os serviços públicos de saúde. Questionamos se uma lista de fatores prognósticos elaborada, em 2007, pelo Multinational Musculoskeletal Inception Cohort Study, poderiam servir também para identificar fatores prognósticos da resposta terapêutica à fisioterapia convencional, em pacientes com lombalgia crônica já estabelecida. Objetivos: Identificar fatores prognósticos para resposta ao tratamento fisioterápico em uma população de pacientes com lombalgia crônica. Materiais e métodos: Foram selecionados 130 pacientes com lombalgia mecânica comum crônica no Ambulatório de Doenças da Coluna da Reumatologia. Estes pacientes foram avaliados inicialmente, após realização de dez sessões de fisioterapia e três meses após a da última sessão. Os pacientes foram classificados como respondedores ao apresentarem melhora na escala numérica de dor (END) e redução no questionário de Roland Morris (QRM). Resultado: A ausência de dor extra- espinhal e medo evitação-trabalho aumentam a chance de melhora na END ao final do tratamento. Já a melhora pelo QRM...

O câncer de laringe é uma das neoplasias mais comuns das vias aéreas superiores. No Brasil a maioria dos casos são diagnosticados nos estádios clínicos III ou IV. Nos tumores T4a os resultados terapêuticos são discordantes na literatura. Alguns estudos referem melhores taxas de sobrevida global com o tratamento cirúrgico e outros demonstraram taxas de sobrevida global semelhantes entre pacientes submetidos a laringectomia total e os submetidos a quimioradioterapia. Concomitante ao surgimento destas novas modalidades terapêuticas, descritas nas últimas décadas, observou-se nos Estados Unidos queda nas taxas de sobrevida dos pacientes com tumores de laringe. O objetivo deste estudo foi avaliar fatores prognósticos em pacientes portadores de carcinoma epidermóide de laringe cT4aN0-3M0 tratados em quatro instituições - em três diferentes países - de acordo com variáveis demográficas, clínicas, terapêuticas e anatomopatológicas. Em relação as variáveis clínicas, foram observadas piores taxas de sobrevida global nos pacientes com mais de 65 anos, nos classificados como ASA III ou IV, nos casos com tumores com extensão para base de língua. Dentre os pacientes submetidos ao tratamento cirúrgico as piores taxas de sobrevida global foram observados nos casos com margens de ressecção comprometidas...

Os objetivos deste trabalho foram: Analisar prospectivamente a eficácia da correlação entre parâmetros clínicos, histológicos, e marcadores de proliferação celular buscando melhores indicadores de prognóstico em casos de mastocitoma canino; Testar o uso de nova ferramenta diagnóstica e prognóstica para mastocitomas caninos: a termografia. Para isso, um total de 20 cães com diagnóstico citológico e histopatológico de mastocitoma tiveram suas formações excisadas e foram utilizados para estudo clínico e imunohistoquímico e dentre estes, 15 também para estudo termográfico. As avaliações imunohistoquímicas incluíram quantificação de AgNORs, PCNA, VEGF, localização de KIT. Os estudos termográficos incluíram análise e correlação das temperaturas no ponto central da formação (SpT), e na área da formação (AT) e em ponto de pele sadia (SpNT) e área equivalente, em pele sadia (ANT). Estatisticamente pode-se demonstrar uma correlação positiva significativa entre a classificação proposta determinada pela presença dos fatores prognósticos e o estadiamento proposto pela WHO. Não foi observada correlação estatística entre tempo livre de doença (óbito, novas formações, recidiva ou metástase) e o estadiamento ou fatores prognósticos. 95% (19/20) dos cães teve suas formações classificadas como Grau II e 5% (1/20) Grau I...

Objective: To identify potential prognostic factors for pulmonary thromboembolism (PTE), establishing a mathematical model to predict the risk for fatal PTE and nonfatal PTE.Method: the reports on 4,813 consecutive autopsies performed from 1979 to 1998 in a Brazilian tertiary referral medical school were reviewed for a retrospective study. From the medical records and autopsy reports of the 512 patients found with macroscopically and/or microscopically,documented PTE, data on demographics, underlying diseases, and probable PTE site of origin were gathered and studied by multiple logistic regression. Thereafter, the jackknife method, a statistical cross-validation technique that uses the original study patients to validate a clinical prediction rule, was performed.Results: the autopsy rate was 50.2%, and PTE prevalence was 10.6%. In 212 cases, PTE was the main cause of death (fatal PTE). The independent variables selected by the regression significance criteria that were more likely to be associated with fatal PTE were age (odds ratio [OR], 1.02; 95% confidence interval [CI], 1.00 to 1.03), trauma (OR, 8.5; 95% CI, 2.20 to 32.81), right-sided cardiac thrombi (OR, 1.96; 95% CI, 1.02 to 3.77), pelvic vein thrombi (OR, 3.46; 95% CI, 1.19 to 10.05); those most likely to be associated with nonfatal PTE were systemic arterial hypertension (OR...

Objective The purpose of this study was to identify the clinical factors associated with time to hCG remission among women with low-risk postmolar GTN. Methods This study included a non-concurrent cohort of 328 patients diagnosed with low-risk postmolar GTN according to FIGO 2002 criteria. Associations of time to hCG remission with history of prior mole, molar histology, time to persistence, use of D&C at persistence, presence of metastatic disease, FIGO score, hCG values at persistence, type of first line therapy and use of multiagent chemotherapy were investigated with both univariate and multivariate analyses. Results Overall median time to remission was 46 days. Ten percent of the patients required multi-agent chemotherapy to achieve hCG remission. Multivariate analysis incorporating the variables significant on univariate analysis confirmed that complete molar histology (HR 1.45), metastatic disease (HR 1.66), use of multi-agent therapy (HR 2.00) and FIGO score (HR 1.82) were associated with longer time to remission. There was a linear relationship between FIGO score and time to hCG remission. Each 1-point increment in FIGO score was associated with an average 17-day increase in hCG remission time (95% CI: 12.5-21.6). Conclusions Complete mole histology prior to GTN...

The CYP2D6 enzyme is crucial for the metabolism of tamoxifen. The CYP2D6 gene is highly polymorphic, and individuals can be extensive, intermediate, or poor tamoxifen metabolizers. The aim of this study was to determine the frequencies of the CYP2D6 *3, *4, and *10 alleles in women with breast cancer who were treated with tamoxifen and analyze the association of enzyme activity with prognostic factors and disease-free survival. We observed a high frequency of CYP2D6 *10, with an allelic frequency of 0.14 (14.4%). The *3 allele was not present in the studied population, and *4 had an allelic frequency of 0.13 (13.8%). We conclude that patients with reduced CYP2D6 activity did not present worse tumor characteristics or decreased disease-free survival than women with normal enzyme activity, as the difference was not statistically significant. We also observed a high frequency of CYP2D6 *10, which had not been previously described in this specific population. This study is the first in north-northeastern Brazil that aimed to contribute to the knowledge of the Brazilian regional profile for CYP2D6 polymorphisms and their phenotypes. These findings add to the knowledge of the distribution of different polymorphic CYP2D6 alleles and the potential role of CYP2D6 genotyping in clinical practice prior to choosing therapeutic protocols.

Pulmonary metastases are among the most common sites for the spread of cancer, particularly with mesenchymal tumors. Despite improvements in cancer therapy, the prognosis remains poor, except for the highly selective group of patients who are considered eligible for surgical treatment and those with chemosensitive tumors. The main objective of this study was to evaluate survival results of 291 patients who underwent thoractomy due to pulmonary metastases between 1953 and 1986. The number of metastases ranged from a minimum of 1 to as many as 30. The type of resection depended on site, size, and number of pulmonary lesions: 154 wedge resections, 49 lobectomies, and 9 pneumectomies. The tumor was not resectable in the remaining 79 patients. Of the prognostic factors analyzed, only type of pulmonary resection (wedge vs. lobectomy vs. pneumectomy vs. unresectable) and disease free interval (DFI) between primary treatment and pulmonary metastases diagnosis ( <=6 months vs. 7-12 months vs. >12 months) were selected as independent predictors of the risk of death in multivariate analysis. A reduced model for bone tumors included disease free interval, sex and histology.

Introduction: Renal cell carcinoma (RCC) is an aggressive disease worldwide. Objective: Study traditional prognostic factors associated with pathological reports and the novel markers survivin and B7-H1 by immunohistochemistry. Methods: In a reference hospital of Porto Alegre, Brazil, we conducted a cross-sectional study of RCC in patients who underwent radical nephrectomy between 2006 and 2009. We selected those who were diagnosed with the most common histologic subtypes: clear cell and papillary RCC. We retrospectively reviewed pathological data to determine traditional prognostic factors, like size, presence of coagulative necrosis, Fuhrman grade and tumor-node metastasis (TNM) system. Besides, we performed an immunohistochemistry (IHC) study with survivin and B7-H1. Results: Our sample had 98 cases, 90% of the cases were composed by clear cell histologic subtype, 73% were tumors classified as T1 and T2 in the TNM system, most were Fuhrman nuclear grade 2 or 3, and 70% were positive for necrosis. In relation to the new prognostic markers, we found 50 cases positive to survivin and 38 to B7-H1. In this investigation of traditional prognostic markers and new markers we observed that only necrosis was associated with positive results of biomarkers. < 0.001). Conclusion: This finding confirms previous studies that necrosis is an important factor to consider in the prognosis of RCC.

Squamous cell carcinoma (SCC) is a cutaneous malignant neoplasm commonly observed in dog and cat. Especially in our country, the SCC represents a serious problem, since chronic exposure to ultraviolet radiation is one of the important factors for the development of the disease. In this way, the objective of this study was establish histomorphological markers as prognostic factors and determine the time and the estimated survival of dogs and cats carriers of SCCs. A survey of cases of SCCs in dog and cat diagnosed at the Regional Diagnostic Laboratory from the Federal University of Pelotas, was performed during the period of 1999 to 2009. Fifty samples were obtained from biopsies and/or necropsies. From the studied cases, 24 animals with the disease were followed for a period of one year. In this study, we used the histological grade and survival time of animals as a criterion to prognostic evaluation. The histological parameters evaluated as peritumoral lymphoplasmacytic infiltration, tissue eosinophilia associated with tumor, mitotic index, arrangement, invasion to adjacent tissues, emboli vascular blood and/or lymphatic, desmoplastic reaction and quantification of AgNORs were confronted with the histological grade and the survival time of affected animals. When the histological parameters were compared with survival...

Blood vascular tumors (hemagioma and hemangiosarcomas) are common neoplasms in dogs and cats, although their frequency of diagnosis is lower than others neoplasms and may reach the skin or organ systems. The hemangioma is a benign, although it can cause organ dysfunction when reaching systemic organs. The hemangiosarcoma represents a serious problem, because their malignant nature is considered one of the soft tissue sarcomas of worse prognosis causing sudden death. In this sense, the objective was to identify the incidence, prognostic parameters and time and survival rate of pets suffering from hemangiomas and hemangiosarcomas. We conducted a survey of cases of hemangiomas and hemangiosarcomas in dogs and cats diagnosed at the Regional Diagnostic Laboratory, Federal University of Pelotas, during the period 1998 to 2010. We retrieved 53 samples from biopsies and/or necropsies. Of the total cases studied, 20 animals with neoplasms were monitored over a period of two years. In this study, we used histopathological parameters, invasion, survival time and location as criteria for assessing prognosis. Histological parameters were evaluated as histological arrangement, cell morphology, mitotic rate, peritumoral lymphoplasmocytic infiltrate...

Diabetische Ulzera stellen eine schwerwiegende Komplikation des Diabetes mellitus dar. In dieser Arbeit wurden prognostische Faktoren (Wundgröße, multiple Ulzerationen, Wundlokalisation, Wunddauer, Infektion, Compliance, Patientenalter, Fußpulse und tcpO2) sowohl im Hinblick auf die Abheilung der Ulzera, als auch auf das Auftreten eines Rezidivs untersucht. Patienten und Methoden: Diese Arbeit umfasste ausschließlich Diabetiker mit abgeheilten Ulzera ohne knöcherne Beteiligung (Wagner II). Jeder Patient wurde mindestens 1 Jahr lang nachuntersucht und mit Hilfe eines modernen Wunddokumentationssystems erfasst. Ergebnisse: Es wurden insgesamt 236 Wunden an 139 Patienten mit abgeheilten diabetischen Ulzera untersucht. Die durchschnittliche Wundgröße betrug 3,34 cm2 (3,34 ± 1,09). Bei 37,4 % der Patienten fanden sich mehrere Wunden. Das durchschnittliche Alter aller Patienten war 68,22 ± 0,90 Jahre. Das Vorhandensein von Fußpulsen oder/und eines tcpO2 > 20 mmHg zeigte nicht nur einen positiven Einfluss auf die Abheilung (p = 0.003 bzw. 0.012), sondern auch niedrigere Rezidivwahrscheinlichkeit (p=0.027 resp. p=0.0013). Während das Patientenalter (<= 60 vs. > 60 Jahre) einen positiven Einfluss auf die Abheilung zeigte, hatte es auf das Auftreten eines Rezidivs keinen Einfluss. Obwohl die Patienten-Compliance (gut vs. schlecht) keinen signifikanten Einfluss auf die Abheilung zeigte (p = 0.16)...

We studied 569 cases of renal cell carcinoma in the file5 of the Department of Pathology of the Nor~vegian Radium Hospital from 1964 to 1974. A nephrectorny had been perfornied in all cases. Clinical information on sex, age, survival time and metastases was traced. The histological slides were examined and turnour growth pattern, cell type, cell shape, nuclear atypia, abnormal nucleoli, nuclear grade, va s c~~l ainrv asion and tumour demarcation mere all evaluated. Besides well-known prognostic factors j ~ ~ cash t uniour stage, presence or absence of metastases and vascular invasion, nuclear grade sas found to be a useful prognostic factor. Younger patients were found to do better than older, and women better than men. Smaller tumours carried a better prognosis than larger and clear cell turnours had a better prognosis than those composed of eosinophilic or basophilic cells. The presence of spindle cells was a bad prognostic omen.

BACKGROUND: There is controversy regarding the optimal therapy for primary non-Hodgkin gastric lymphoma with some authors defending surgical extirpation either alone or in association with radiotherapy and or chemotherapy, especially in relation to the earlier stages of the disease. AIM: To analyze the clinical-pathological features and the results of management approaches for patients with primary early-stage non-Hodgkin's lymphoma of the stomach operated in Surgical Gastroenterology Department, "Hospital do Servidor Público Estadual", São Paulo, SP, Brazil. The literature is reviewed to highlight the aspects of diagnosis, prognostic factors and role of the various treatment regimens. METHOD: Sixteen patients with primary early-stage gastric lymphoma underwent curative surgical treatment. The variables analyzed were age, sex, location, size, type of surgery, number of lesions, depth of invasion, histological type in accordance with Kiel's classification, involvement of lymph nodes, Ann Arbor stage classification modified by Musshoff and Schmidt-Vollmer, histological grade, margins, adjuvant therapy, clinical course and survival. RESULTS: Ten patients (62.5%) underwent subtotal gastrectomy and six (37.5%) underwent total gastrectomy. The majority (9/56.2%) of the lesions were located in the antrum. Single lesions (10/62.5%) were more frequent than multiple lesions (6/37.5%). Thirteen patients (81.2%) were classified as stage IE and three (18.7%) as stage IIE1. Primary gastric lymphoma classified histologically as low or high grade was presented by 10 (62.5%) and 6 (37.5%) patients...

CONTEXT: In Hodgkin's disease, each clinical or pathologic stage can be related to the extent of the area involved and predicts the next anatomical region at risk for tumor dissemination. OBJECTIVE: To determine the best prognostic factors that could predict survival in non-Hodgkin lymphoma cases. DESIGN: A retrospective study. LOCATION: Department of Hematology and Transfusion Medicine, Universidade Federal de São Paulo - Escola Paulista de Medicina. PARTICIPANTS: 142 patients with non-Hodgkin lymphoma diagnosed between February 1988 and March 1993. MAIN MEASUREMENTS: Histological subset, Sex, Age, Race, B symptoms, Performance status, Stage, Extranodal disease, Bulk disease, Mediastinal disease, CNS involvement, BM infiltration, Level of DHL, Immunophenotype. RESULTS: In the first study (113 patients), the following variables had a worse influence on survival: yellow race (P<0.1); ECOG II, III e IV (P<0.1) and extranodal disease (P<0.1) for high grade lymphomas; constitutional symptoms (P<0.1), ECOG II, III e IV (P<0.1) and involvement of CNS (P<0.1) for intermediate grade and the subtype lymphoplasmocytoid (P=0.0186) for low grade lymphomas. In the second survey (93 patients), when treatment was included...

INTRODUCTION: Knowledge of prognostic factors in end-stage renal disease patients has improved dialysis management and methods for reducing morbidity and mortality, underlining the importance of identification, prevention and control of these factors. OBJECTIVE: Identify factors affecting prognosis (survival or death) in hemodialysis patients at the Medical-Surgical Research Center in Havana over a ten-year period. METHODS: Descriptive, prospective study of 81 end-stage renal disease patients who received hemodialysis at the Medical-Surgical Research Center from 1995 to 2004. Prognostic factors were identified at initiation of and during dialysis treatment, using chi square, t test, McNemar test, Kaplan Meier analysis, log-rank test and Cox regression model, with significance threshold set at p <0.05. RESULTS: Hypertension and diabetes were the leading causes of end-stage renal disease. Six patients were referred late. Mean survival was 4.4 years; with survival of 86.6%, 54.7% and 26.6% at one, three and five years respectively. Factors predictive of decreased survival that were most frequent at initiation of hemodialysis were hypertension and chronic anemia (both present in 95.9% of cases); malnutrition, hypoalbuminemia, cardiovascular disease and chronic liver disease increased during treatment while hypertension decreased. In multivariate analysis...
