For the reduction and control of the adverse effects, Dental Care Protocol is applied to patients with oral cancer by dental surgeon team before, during and after radiotherapy and chemotherapy. Objective: The aim of this study was to investigate the adhesion of patients with oral cancer to a Dental Care Protocol and its Impact in the interruption and survival. Patients and methods: In this study 133 cases of oral cancer undergoing radiotherapy were selected. The patients were classified according to the period of dental adhesion: no adhesion (group I), adhesion less than or equal to 6 months (group II) and adhesion higher than 6 months (group III). Clinic and pathological aspects, occurrence of interruption of radiotherapy, disease-free survival and overall survival were investigated. Results: The incidence of radiotherapy interruption due to symptoms was statistically significant in group III compared to group I (p = 0.01). The frequency and duration of interruption due to symptoms were not statistically significant between groups. The conclusion of radiotherapy rate was statistically significant in the group that exceeded 6 months of dental adhesion (p = 0.02). Patient’s survival was higher in group III (p = 0.01) when compared to the other groups. Conclusion: The adhesion to a dental care protocol did not have any impact on the radiotherapy interruption due to the occurrence of symptoms, however, patients who had higher adhesion to the Dental Care Protocol showed a higher rate of disease-free survival and overall survival. / Modalidades de tratamentos para o câncer de cavidade oral resultam em efeitos adversos locais que podem gerar interrupções da radioterapia e consequentemente influenciar na sobrevida do paciente. Para a redução e controle dos efeitos adversos, protocolos de preparo do paciente oncológico são estabelecidos por equipes odontológicas antes, durante e pós-tratamento radioterápico e quimioterápico. Objetivo: Verificar a adesão dos pacientes portadores de câncer de cavidade oral ao protocolo preventivo odontológico e seu impacto na interrupção da radioterapia e sobrevida do paciente. Pacientes e método: Neste estudo foram selecionados 133 casos de câncer de cavidade oral submetidos à radioterapia. Os pacientes foram classificados de acordo com o tempo de adesão odontológica: sem adesão (grupo I), adesão inferior ou igual a 6 meses (grupo II) e adesão superior a 6 meses (grupo III). Foram investigadas as características clínico-patológicas, ocorrência de interrupção da radioterapia, sobrevida livre de doença e sobrevida global. Resultados: A ocorrência de interrupção por sintomas foi estatisticamente significante no grupo III quando comparado ao grupo I (p=0,01). A frequência e a duração de interrupção por sintomas não foram estatisticamente significante entre os grupos. A conclusão da radioterapia foi estatisticamente significante no grupo com adesão superior a 6 meses (p=0,02). A sobrevida dos pacientes foi maior no grupo III (p=0,01) quando comparado aos demais grupos. Conclusão: A adesão ao protocolo não teve impacto sobre interrupção da radioterapia devido ocorrência da interrupção por sintomas, no entanto, pacientes que tiveram adesão ao protocolo preventivo odontológico apresentaram um melhor índice de sobrevida livre de doença e de sobrevida global.

A escolha do sistema de estadiamento dos carcinomas bem diferenciados da tireóide continua um desafio aos clínicos que atuam no tratamento das doenças da tireóide. Em nosso meio, faltam estudos que nos proporcionem tais modelos prognósticos ou que validem os previamente publicados. Este estudo retrospectivo visa avaliar o grau de aplicabilidade destes sistemas já descritos em pacientes de nossas instituições. Foram analisados 556 pacientes de dois grandes centros de tratamento oncológico no Brasil. O seguimento médio destes pacientes foi de 7,6 anos. Foram incluídos somente pacientes que obtiveram tratamento inicial cirúrgico no período de 1980 a 2000. A análise estatística foi feita utilizando o pacote estatístico SPSS for Windows 15.0. Analisados os pacientes do estudo, 81,2% eram do sexo feminino e 59,4% com idade inferior a 45 anos. O carcinoma papilífero e seus subtipos estiveram presentes em 83,3% da amostra. A análise multivariada de nossa população evidenciou como fatores de risco independentes a idade, o gênero, o tamanho do tumor e a presença de metástase à distância. O método da proporção da variação explicada (PVE) mostrou que os melhores sistemas de estadiamento/escore prognóstico para carcinoma bem diferenciado da tireóide foram TNM, EORTC, OSU e AMES. No caso dos portadores de carcinoma papilífero, foram os sistemas Ankara, MACIS e UAB & MDA os melhores preditores do desfecho da amostra. Dentre os modelos estudados, a maioria - exceto os sistemas de Murcia e Noguchi para homens - foi capaz de prever o desfecho de nossa amostra em menor ou maior grau. O sistema TNM (UICC/AJCC) esteve entre os melhores sistemas de estadiamento/escores prognósticos pela classificação do PVE. Foi capaz de predizer melhor o desfecho da nossa amostra e da população de outros estudos, incluindo os realizados entre a população européia, asiática e norte-americana. Isto sugere que este sistema deva ser mais amplamente utilizado para descrever o estadiamento e inferir o prognóstico nas publicações sobre carcinoma bem diferenciado da tireóide mundialmente / Background: Choosing the best well-differentiated thyroid carcinoma (WDTC) prognostic score remains a challenge for physicians. No studies have been done with Latin American populations to validate previous results from other continents. This retrospective study evaluates the goodness of fit of staging systems/prognostic scores published in our patient institutions and investigates a staging system that can provide a better WDTC prognosis. Methods: This study includes patients submitted to surgical resection for WDTC, from 1980 to 2000, in two Latin American cancer centers. A total of 556 patients were reviewed and analyzed. Thirteen well-known and published staging systems/prognostic scores were tested in this patient population. Results: Of the 556 patients, 81.2% were female and 59.4% were aged under 45 years. Papillary carcinoma (PTC) and its subtypes were present in 83.3% of the cases. The multivariate analysis showed age, gender, tumor size and distant metastasis as independent risk factors for these patients. The proportion of variance explained (PVE) method showed that the best validated staging systems/prognostic scores for WDTC patients were TNM, EORTC, OSU and AMES. In the case of PTC patients, Ankara, MACIS, and UAB & MDA were the best predictor of patient outcome. Conclusions: Except for Murcia e Noguchi for male systems, all the other prognostic scores were validated for our sample. We found that TNM (UICC/AJCC system) was consistently among the top four in the ranking of staging systems/prognostic scores that mostly predicted the prognosis of our patient population and others, including European, Asian and North-American populations suggesting that this system should be used more widely to report prognostic results in WDTC publications worldwide

The treatment of clinically locally advanced prostate carcinoma (stage cT3) remains controversial. One of the main reasons for this controversy results from the substantial staging error attached to the clinical diagnosis cT3 with overstaged T2 tumors and understaged node-positive cases. Treatment options in this situation include radical prostatectomy, external beam radiotherapy, immediate or delayed androgen deprivation treatment and the so-called ‘watchful waiting’. Acceptable and often surprisingly good tumor-specific survival rates have been reported for radical prostatectomy in pT3 series – based on good clinical case selection – approaching those of pT2 series. In lymph node-positive pT3 cases, adjuvant hormone deprivation seems to prolong survival which it does not in lymph node-negative pT3 disease. A benefit of adjuvant external beam radiotherapy after radical prostatectomy for pT3 cases in prolonging overall survival has not been shown, despite the fact that it can prevent or delay biochemical and local recurrence. External beam radiotherapy as the only treatment for cT3 disease results in unfavorable tumor-specific survival rates, which can be significantly improved with adjuvant hormonal treatment with LHRH agonists. If, in case of advanced age and/or significant comorbidity, primary hormonal treatment is chosen, early hormonal deprivation therapy seems to offer marginal benefits in survival compared to delayed treatment. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.

Freshwater mussels (Unionidae) in the United States have experienced dramatic declines, and 25% species are listed as federally endangered. Hence, recovery plans for endangered species proposed a strategy of propagation of young mussels for release to natal rivers to augment declining populations. In this study, I conducted laboratory experiments, assessed site suitability for mussel restoration, and evaluated survival and growth rates of released mussels to meet the requirements of recovery plan. I conducted multiple experiments to develop an improved protocol for juvenile mussel propagation and culture. Significantly greater survival and growth rates were found in newly metamorphosed juveniles of the rainbow mussel (Villosa iris) reared in a substrate of fine sediment and one-month-old juveniles of wavy-rayed lampmussel (Lampsilis fasciola) fed on natural food in pond water. Bio-filter media greatly increased water quality by reducing the concentration of ammonia and nitrite. The negative impacts of flatworm predation and filamentous algae in juvenile culture were controlled, and juvenile escapement was prevented. Juvenile mussels were successfully produced and cultured to stockable size (>15 mm) for release. I released laboratory-propagated mussels at three historically important sites in Clinch and Powell rivers for the assessment of site suitability. Use of cages was the most effective method to determine site suitability because the free-released mussels (untagged, tagged) had low catchability. Mussels released at Horton Ford, Clinch River, exhibited significantly faster growth. Horton Ford is the most suitable site, while environmental conditions at Fugate Ford, Powell River, are deemed unsuitable for mussel restoration and recovery. To facilitate the detection of released mussels, I applied Passive Integrated Transponder tags to laboratory-produced juveniles of the endangered Cumberlandian combshell (Epioblasma brevidens) and released them near Brooks Bridge, Powell River. The detection probability increased above 98%. I developed a set of hierarchical Bayesian models incorporating individual variations, seasonal variations, periodic growth stages and growth cessation to estimate survival, detection probability and growth of released mussels in a changing environment. Mussels of E. brevidens exhibited great survival (> 99% per month) and growth, indicating suitable conditions for recovery of this endangered species at this site. / Ph. D.

Sotalia guianensis is listed as “Data Deficient” by the IUCN and as “Vulnerable” in Colombia. This study aimed to advance understanding of the ecology of this species and its habitats, and to provide information to conservation management in the southern Gulf of Morrosquillo, Colombia. Systematic boat-based surveys were conducted during 395 days in 2002-2006 and 2009-2010, following established routes. Total survey effort was 15,199 km in an area covering ~ 310km². Fine scale habitat use and behavioural modelling, photo-identification and mark-recapture techniques were used to analyze the ecological patterns for this species. The most recent abundance estimate of dolphins using the study area during dry and rainy seasons, varied from 225 (CV = 0.34; 95% CI: 118-426) to 232 (CV = 0.32; 95% CI: 127-246). Annual survival rate is estimated at 0.948 (95% CI = 0.876-0.980). Overall density was 0.74/km². Dolphins were present year-round in the whole study area. Results indicate that they do not use the study area uniformly and that the use of particular zones is related to eco-geographic variables. Dolphins showed a preference for waters greater than 3m in depth with a slightly increased preference for waters about 5m and 15-25m deep. The average group size was nine individuals. Some individuals show long-term high site fidelity to some zones within the study site boundaries. Even though the site fidelity to feeding areas varied individually, all the individuals focused primarily on one specific area. Foraging was among one of the most predominant behaviours observed. The individual movements show that some dolphins use both bay and gulf waters. Dolphins show a range of surface cooperative foraging and feeding strategies. These cooperative behaviours were influenced by zone, group size and prey type. Based on these results an area of special management for the species will be created in Colombia.

INTRODUÇÃO: O melanoma cutâneo constitui cerca de 3% de todos os tumores da pele. Atinge indivíduos jovens com média de idade de aparecimento entre 50 e 58 anos. Em torno de 20% dos doentes apresentarão doença avançada e morrerão antes de completar cinco anos de sobrevida. CASUÍSTICA E MÉTODOS: Neste estudo retrospectivo de 364 casos acompanhados de maio de 1993 a janeiro de 2006 descreveram-se as variáveis: sexo, idade, cor, localização da lesão primária, tipo de crescimento, espessura de Breslow, nível de Clark, presença de ulceração, estadiamento e suas correlações. RESULTADOS: Predominou o sexo feminino (58,8%) resultando em uma proporção de 1,4 mulheres para cada homem. A média das idades dos pacientes foi de 58,9 anos e a mediana de 61,0 anos. Pacientes não-brancos constituíram 13,7% da amostra. Para homens e mulheres o melanoma cutâneo localizou-se, predominantemente no tronco (24,3-38,0%) e pés (21,4-23,9%). O melanoma acrolentiginoso representou 22,3% de toda amostra. Os padrões melanoma expansivo superficial e melanoma nodular (p < 0,001) e lesões no tronco (52,8%) predominaram nos indivíduos brancos. O melanoma acrolentiginoso (64%) e a localização nos pés (68,2%)prevaleceram nos pacientes não-brancos. Observou-se minoria de casos com lesão primária in situ (14,6%- EC 0) e alto percentual de melanoma cutâneo espesso (39,7% > 4,0 mm). Presença de ulceração foi observada em 13,4% para tumores finos (= 1,0 mm). Homens apresentaram lesões mais espessas (p = 0,011) e ulceradas (p < 0,001) em relação às mulheres, assim como idosos em relação à não idosos (p = 0,021 para a espessura e p = 0,015 para ulceração). A sobrevida média para os pacientes com doença localizada foi de 97,8 meses e a taxa de sobrevida específica para melanoma cutâneo foi de 85,1% em três anos. CONCLUSÕES: Esta amostra constituiu-se de pacientes com tumores espessos e ulcerados denotando diagnóstico tardio do melanoma cutâneo e pior prognóstico. Caracterizou-se por apresentar predomínio de mulheres, de pacientes não-brancos, de lesões nas extremidades e de melanoma acrolentiginoso. / INTRODUCTION: Cutaneous melanoma represents around 3% of all skin tumors. Affecting young patients, with mean age between 50 and 58 years old. About 20% of the patients will have advanced disease and will die before five years of survival. CASUISTIC AND METHODS: In this retrospective study of 364 cases recorded from May 1993 to January 2006 at the Melanoma Unit of Santa Casa de São Paulo the following variables were described: sex, age, skin color, tumor site, growth pattern, tumor thickness, Clark level, ulceration, staging and their correlations. RESULTS: Female (58,8%) prevailed resulting in 1,4 women for each man. The mean age of the patients was 58,9 years old and the median, 61,0 years old. Non-white patients were 13,7% of the sample. The anatomic site of cutaneous melanoma on men and women prevailed at trunk (24,3 – 38,0%) and feet (21,4 – 23,9%). Acral entiginous melanoma represented 22,3% of the cohort. Superficial expansive melanoma and nodular melanoma patterns (p<0,001) and trunk lesions (52,8%) predominated on white patients. Acral lentiginous melanoma (64%) and feet anatomic site 68,2%) prevailed on non-white patients. In situ primary lesions were observed in few cases (14,6% - EC 0) and there was high percentage of thick cutaneous melanoma (39,7% > 4,0 mm). In thin tumors (=1,0 mm) were found 13,4% of ulceration. Thickener (p = 0,011) and ulcerated lesions (p < 0,001) were found more in male and in elderly patients (p = 0,021 for thickeness and p = 0,015 for ulceration). The mean survival of patients with local disease was 97,8 months and the three-year survival rate for cutaneous melanoma was 85,1%. CONCLUSIONS: The cohort consisted mostly of thick and ulcerated tumors, which meant late diagnosis and bad prognosis. Also distinguished by considerable prevalence of female, non-white patients, limb lesions and acral lentiginous melanoma.

Sepse é a resposta inflamatória sistêmica decorrente de infecção grave, com alto índice de mortalidade, tornando-se um grave problema de saúde pública. Apesar dos inúmeros estudos realizados em busca de alternativas terapêuticas, o entendimento acerca dos mecanismos envolvidos na doença permanece restrito. A interação entre o metabolismo lipídico e a resposta inflamatória tem sido intensamente investigada. Neste estudo, avaliou-se a influência da proteína de transferência de colesterol esterificado (CETP) - glicoproteína plasmática que promove a transferência de lípides entre lipoproteínas - na resposta inflamatória. Inicialmente, foram comparados camundongos transgênicos para CETP humana (CETP) e controles irmãos não transgênicos (WT) submetidos ao modelo de sepse polimicrobiana de ligadura e perfuração do ceco (CLP), avaliando a taxa de sobrevida e o perfil inflamatório entre os grupos. Em seguida, a resposta inflamatória em macrófagos de peritônio de camundongos estimulados com LPS na ausência ou presença da CETP exógena (CETP humana recombinante) e endógena (macrófagos de animais CETP) foi analisada. Verificou-se que camundongos CETP apresentaram maior taxa de sobrevida, maior migração de linfócitos para o foco infeccioso, menores concentrações plasmáticas de IL-6 e menor expressão proteica do receptor Toll-like 4 (TLR4) e da enzima aciloxiacilo hidrolase (AOAH) no fígado, comparados aos WT. Nos macrófagos, observou-se que a presença da CETP recombinante foi capaz de se ligar ao LPS, pela análise da microscopia confocal, e, em cultura, reduziu de forma dose dependente a captação de LPS, a expressão de TLR4, a ativação do NF-kB (p65) e a secreção de IL-6 para o sobrenadante do cultivo celular. Os dados obtidos com os macrófagos de animais CETP corroboraram, em parte, os encontrados com a utilização da CETP exógena. Houve redução da captação de LPS e da ativação do NF-kB (p65), sem alteração na expressão de TLR4 e secreção de IL-6. Entretanto, apresentaram redução das concentrações de TNF-alfa celular e no sobrenadante de cultura. Dessa maneira, foi possível concluir que a CETP atua como agente modulador da resposta inflamatória induzida pela CLP e em macrófagos estimulados pelo LPS. Esses achados devem ser considerados nas doenças inflamatórias e nos futuros estudos relacionados à inibição da CETP, além de estabelecer novas perspectivas de tratamento da sepse / Sepsis is a systemic inflammatory response due to serious infection with high mortality rate, which has become a serious problem for public health. Despite numerous studies seeking for therapeutic alternatives, the understanding of the mechanisms involved in this disease remains limited. The interaction between lipid metabolism and inflammatory response has been intensively investigated. In the present study it was evaluated the influence of CETP (cholesteryl ester transfer protein) - plasma glycoprotein that promotes the transfer of lipids between lipoprotein - in the inflammatory response. Initially transgenic mice for human CETP (CETP) were compared to non transgenic control mice (WT) after polymicrobial sepsis induced by cecal ligation and puncture (CLP), to determine survival rate and the inflammatory profile between groups. Then, macrophages isolated from peritoneal cavity stimulated with LPS in the presence or absence of exogenous CETP (recombinant human CETP) and endogenous CETP (macrophages from CETP mice) were analyzed. It was found that CETP mice showed a higher survival rate, a greater lymphocyte migration to infectious focus, a lower IL-6 plasma concentration and a decrease in Toll-like receptor 4 (TLR4) and acyloxyacyl hydrolase enzyme (AOAH) protein expression in the liver in comparison to WT mice. In macrophages, recombinant CETP was able to bind to LPS, by confocal microscopy analysis and in cell culture, it was observed that in the presence of the recombinant CETP macrophages presented decreased in LPS uptake, TLR4 expression, NF-kB activation (p65) and IL-6 secretion into the cell culture medium. Furthermore, the results with macrophages from animals CETP corroborate partly with what was found in the exogenous experiments. LPS uptake and NF-kB activation (p65) were reduced, but no difference regarding the expression of TLR4, nor the IL-6 secretion to the cell culture medium. However, the CETP group also showed reduced levels of TNF-alfa both in macrophages and in the culture supernatant. Thus, we conclude that CETP acts as modulator of the inflammatory response induced by CLP and in the macrophages stimulated by LPS. In addition, new therapeutic perspectives could be established

No. of bitstreams: 0 Previous issue date: 2010-10-28 / Em 2002, o Estado de Mato Grosso aderiu à segunda fase de intensificação Programa Nacional de Controle do Câncer do Colo do Útero (PNCCU) como medida de enfrentamento das altas taxas da doença e de morte por neoplasia cervical. Com o objetivo de analisar os principais resultados do PNCCU, foi feito um estudo em duas partes. A primeira parte teve como objetivo levantar o perfil da doença e a cobertura do exame rastreamento pelo PNCCU no Estado. Os objetivos da segunda parte foram: analisar o seguimento clínico da população rastreada, analisar as diferentes características evolutivas da doença associadas aos fatores sócio-demográficos e clínicos, bem como analisar o risco de óbito e a taxa de sobrevida estratificada pelas variáveis sócio-demográficas e clínicas das mulheres que apresentaram carcinoma invasivo. Na primeira parte, foi utilizado estudo do tipo transversal e na segunda parte, foi realizado um estudo de coorte. O período do estudo compreendeu de 2002 a 2007 e abrangeu todos os municípios do Estado de Mato Grosso. A população estudada na primeira fase do estudo correspondeu todas as mulheres que fizeram o exame de rastreamento no ano de 2002. Na segunda parte do estudo, a população correspondeu a uma amostra aleatória representativa das mulheres que apresentaram alterações citológicas na primeira fase do estudo, totalizando 323 mulheres. A fonte de dados utilizada foi o sistema de informação oficial de saúde, dentre eles o SISCOLO, SIM, APAC, além de dados oficiais da Secretaria Estadual de Saúde/MT (SES/MT), dados disponíveis no site do INCA e do DATASUS e prontuários clínicos. Para análise estatística dos dados foram utilizadas técnicas descritivas e inferenciais. Na parte descritiva foram utilizados tabelas, gráficos e medidas de posição e de dispersão. Para avaliar a o risco de adoecer por carcinoma cervical invasor foi utilizado regressão logística univariada e multivariada. Para analisar a taxa de sobrevida global foi utilizado o estimador de Kaplan-Meier e para analisar os fatores prognósticos, foi utilizado o modelo de riscos proporcionais de Cox. Dentre os principais resultados, destaca-se que no período estudado, Mato Grosso apresentou taxas de incidência elevadas, acima da média nacional. Os dados do seguimento clínico mostraram os diferentes desfechos, dentre eles, destaca-se que: entre as 323 mulheres, 18 (6,2%) foram a óbito tendo o câncer do colo do útero como causa básica da morte. Foi analisado o risco de a doença evoluir para o carcinoma invasor, segundo as variáveis sócio-demográficas e clínicas, sendo que as variáveis: faixa etária, estado civil, tabagismo, menarca e município foram as que apresentaram forte associação com a doença na fase invasora. Já na análise de sobrevivência, a taxa de sobrevida global em 60 meses, estimada pelo método de Kaplan-Meier, foi de 66,7%. No modelo final de risco proporcional de Cox, as variáveis com maior risco de óbito foi o estágio avançado da doença e a raça/cor. Estes dados levam a concluir que a doença no Estado de Mato Grosso tem uma determinação social muito grande, considerando a dificuldade de acesso aos serviços de saúde da população desfavorecida pelas condições raciais, sócio-econômicas, e chegam aos serviços com a doença em fase adiantada, quando a chance de sobrevivência é muito pequena. Conclui-se que para o efetivo combate a doença são necessárias políticas governamentais, como o PNCCU, que garantam a universalidade da assistência, principalmente da população desfavorecida socialmente. / In 2002, the State joined the second phase of intensification of the National Program for the Control of Cervical Cancer (PNCCU) as a measure to deal with the high rates of the disease and of death by cervical neoplasia. With the aim of analyzing the main PNCCU results, a two-stage study was carried out. The first phase aimed at presenting the disease profile and the coverage of the screening exam by the PNCCU in the State. The aims of the second phase were to analyze the clinical follow-up of the population that was screened, analyze the different evolutionary characteristics of the disease associated to socio-demographic and clinic factors, as well as analyze the factors associated to death risk and the stratified survival rate by the socio-demographic and clinical variables of women that presented invasive carcinoma. In the first part, the cross-sectional study was used and a cohort study was used in the second phase. The period of study was from 2002 to 2007 and comprised all the municipalities of the State of Mato Grosso. The population studied in the first phase of the study was all the women who had undergone the screening test in 2002. The population used in the second phase of the study was a representative random sample of those that presented cytological alterations in the first phase of the study, a total of 323 women. The source of data used was the official health information system, among them the SISCOLO, SIM, APAC, and also the official data of the State Health Department/MT (SES/MT), data available in the INCA and DATASUS sites and medical records. For the statistical analysis of the data, descriptive and inferential techniques were used. In the descriptive part, tables, graphics and position and dispersion measures were used. In order to evaluate the risk of being sick due to invasive cervical carcinoma, the univariate and multivariate logistic regression analysis was used. The Kaplan-Meier estimator was used to analyze the survival rate and to analyze the prognostic factors, the Cox proportional hazards model was used. Among the main results it is highlighted that in 2002, Mato Grosso presented high incidence rates, above the national average. The data of the clinical follow up showed the different clinical outcomes, among the 323 women, 18 (6,2%) died having as the basic cause of death the cervical cancer. The risk of the disease developing into the invasive carcinoma was analyzed according to the socio-demographic and clinical variables, and the variables: age group, marital status, smoking history, menopause and municipality were those that presented a strong association with the disease in the invasive phase. However, in the survival analysis, the global survival rate in 60 months, estimated by the Kaplan-Meier method, was of 66,7%. In the final Cox proportional hazards model, the variables with higher death risk was the advanced stage of the disease and the race/color. These data lead to a conclusion that the disease in the State of Mato Grosso has a very large social determination, considering the difficulties in the access to the health services by the population affected by racial, socio-economic conditions that arrive in the health services with the disease in an advanced stage, when the survival probability is very small. The conclusion is that for the effective fight against the disease governmental policies such as the PNCCU are necessary, and that the universality of the assistance be guaranteed, mainly to the socially disadvantaged population. / TEDE / BV UNIFESP: Teses e dissertações
