ABSTRACT

SUMMARY OBJECTIVES: The aim of this study was to evaluate CD56 immunostaining in the stroma of benign and malignant ovarian epithelial neoplasms and associate the CD56 immunostaining with prognostic factors and survival in ovarian cancer. METHODS: Patients with ovarian epithelial neoplasia (n=77) were studied with a prospective cohort. The CD56 immunostaining was evaluated in the peritumoral stroma. Two groups were evaluated: benign ovarian neoplasms (n=40) and malignant ovarian neoplasms (n=37). Data were recorded for histological type and grade, International Federation of Gynecology and Obstetrics staging, molecular subtype, and lymph node metastases. Fisher's exact test and Kaplan-Meier survival curves were used, with a significance level of ≤0.05. RESULTS: We found greater CD56 stromal immunostaining in malignant neoplasms when compared to the group of benign neoplasms (p=0.00001). There was no significant difference in relation to the prognostic factors and survival. CONCLUSION: Malignant ovarian neoplasms showed higher stromal CD56 immunostaining. As the prognostic value of natural killer in ovarian cancer is controversial, knowing the specific function of each cell present both in the tumor tissue and systemically may help guide successful immunotherapies in the near future.

ABSTRACT

Abstract Objective To evaluate the antitumoral role of γδ TDC cells and αβ TDC cells in an experimental model of breast cancer. Methods Thirty female Balb/c mice were divided into 2 groups: control group (n=15) and induced-4T1 group (n=15), in which the mice received 2 x 105 4T1 mammary tumor cell line. Following the 28-day experimental period, immune cells were collected from the spleen and analyzed by flow cytometry for comparison of αβ TDC (TCRαβ+ CD11c+MHCII+) and γδ TDC (TCRγδ+CD11c+MHCII+) cells regarding surface markers (CD4+ and C8+) and cytokines (IFN-γ, TNF-α, IL-12 and IL-17). Results A total of 26.53% of γδ TDC- control group (p<0.0001) - the proportion of αβ TDC was lower in splenic cells than γδ TDC; however, these 2 cell types were reduced in tumor conditions (p<0.0001), and the proportion of IFN-γ, TNF-α, IL-12 and IL-17 cytokines produced by γδ TDC was higher than those produced by αβ TDC, but it decreased under conditions of tumor-related immune system response (p<0.0001). Conclusion Healthy mice engrafted with malignant cells 4T1 breast tumor presented TDC with γδ TCR repertoire. These cells express cytotoxic molecules of lymphocytes T, producing anti-tumor proinflammatory cytokines.


Resumo Objetivo Esclarecer o possível papel antitumoral das células TDC γδ e TDC αβ em um modelo experimental de câncer de mama. Métodos Trinta baços de camundongos Balb/c analisados por citometria de fluxo, separados entre grupo controle (n=15) e o grupo tumoral induzido por 4T1 (n=15). Resultados Presença de 26,53% de TDC γδ nos camundongos do grupo controle (p<0,0001), proporção de TDC αβ menor em células esplênicas do que TDC γδ; no entanto, estes dois tipos de células são reduzidos emcondições tumorais (p<0,0001), e a proporção de citocinas IFN-γ, TNF-α, IL-12 e IL-17 produzidas pelas célula TDC γδ foi maior do que as produzidas pelas células TDC αβ, mas foram diminuídas sob condições de resposta ao sistema imunológico relacionada ao tumor (p<0,0001). Conclusão Camundongos saudáveis induzidos ao tumor de mama 4T1 apresentaram TDC com repertório TCR γδ. Estas células expressam moléculas citotóxicas de linfócitos T, produzindo citocinas proinflamatórias anti-tumor.

ABSTRACT

SUMMARY OBJECTIVE To relate disease-free survival and overall survival with type I and type II ovarian cancer and preoperative laboratory parameters biomarkers. METHODS A retrospective study was carried out based on the collection of data from medical records of patients with ovarian tumors. Kaplan-Mayer curves were drawn based on the statistical analysis of the data and were compared using the Log-rank test. RESULTS Disease-free survival in type I ovarian cancer was significantly higher than in type II (p=0.0013), as well as in those with normal levels of CA-125 (p=0.0243) and with a platelet-lymphocyte ratio (PLR) lower than 200 (p=0.0038). The overall survival of patients with type I ovarian cancer was significantly higher than in patients with type II, as well as in patients with normal CA-125 serum levels (p=0.0039) and those with a preoperative fasting glucose of less than 100 mg/dL. CONCLUSION CA-125 levels may predict greater overall and disease-free survival. PLR < 200 may suggest greater disease-free survival, whereas normal fasting glucose may suggest greater overall survival.


RESUMO OBJETIVO Relacionar a sobrevida livre de doença e sobrevida global com câncer de ovário tipos I e II, assim como com parâmetros laboratoriais pré-operatórios biomarcadores. MÉTODOS Estudo retrospectivo realizado com base na coleta de dados de prontuários de pacientes com tumor ovariano. As curvas de Kaplan-Mayer foram realizadas em relação à análise estatística dos dados, sendo comparadas pelo teste de Log-rank. RESULTADOS A sobrevida livre de doença nas pacientes com câncer de ovário tipo I foi significativamente maior do que nas pacientes com câncer de ovário tipo II (p = 0,0013), bem como maior naquelas com níveis normais de CA-125 (p = 0,0243) e com relação plaquetas-linfócitos (RPL) inferior a 200 (p = 0,0038). A sobrevida global de pacientes com câncer de ovário tipo I foi significativamente maior do que em pacientes com tipo II, maior em pacientes com níveis séricos normais de CA-125 (p = 0,0039) e naquelas com glicemia de jejum pré-operatória menor que 100 mg / dL. CONCLUSÃO Os níveis de CA-125 podem predizer uma sobrevida global e livre de doença. A RPL < 200 pode sugerir uma maior sobrevida livre de doença, enquanto uma glicemia normal de jejum, uma maior sobrevida global.

ABSTRACT

Abstract Ovarian cancer is the leading cause of death among gynecologic tumors because in most of the cases (75%), the disease is diagnosed in advanced stages. Screening methods are not available since the disease is rare, and the tested methods, such as ultrasound and CA125, were not able to decrease the mortality rate for this type of cancer. This article discusses the main risk factors for ovarian cancer, and the potential clinical and surgical strategies for the prevention of this disease.


Resumo O câncer de ovário é a principal causa de morte entre os tumores ginecológicos, já que na maioria dos casos (75%) o diagnóstico ocorre em estádios avançados. Métodos de rastreamento não estão disponíveis, já que a doença é rara, e osmétodos diagnósticos, como ultrassonografia e CA 125, não são capazes de reduzir a taxa de mortalidade desse câncer. Este artigo discute os principais fatores de risco para o câncer de ovário e as possíveis estratégias clínicas e cirúrgicas para a prevenção dessa doença.

ABSTRACT

Avaliar a flexibilidade da cadeia muscular posterior, utilizando o método proposto por Wells e Dillon, antes e após cada sessão de hidroterapia. Foi verificada a flexibilidade de três crianças com Paralisia Cerebral (PC) diparéticas, com idades entre sete a dez anos. Os valores de flexibilidade foram aferidos, utilizando o Flexômetro de Wells. Houve aumento significativo da flexibilidade da cadeia muscular posterior dos pacientes após cada sessão de hidroterapia, tanto na avaliação em grupo quanto individual, assim como antes da primeira sessão de hidroterapia quando comparada com a última. O estudo sugere que a hidroterapia promove melhora da flexibilidade em relação à cadeia muscular posterior de crianças com PC diparéticas, pelo relaxamento global e consequente diminuição do tônus muscular, quando associada a exercícios de alongamentos passivos.


To evaluate the flexibility of the posterior muscle chain using the method proposed by Wells and Dillon, before and after each hydrotherapy session. The study verified the flexibility of three children with diplegic cerebral palsy (CP), aged 7 to 10. The values of flexibility were measured using the Wells? Flexometer. There was a significant increase in the flexibility of posterior muscle chain of the patients after each session of hydrotherapy, both in the individual evaluation and in the group, as well as before the first session of hydrotherapy compared to the last. The study suggests that hydrotherapy promotes the improvement of flexibility, by relaxation of muscle tone of children with diplegic CP, in relation to the posterior muscle chain, when combined with passive stretching exercises.

ABSTRACT

The objective of this study was to investigate whether malnourished autopsied adults would present higher frequency of pneumonitis than non-malnourished ones would. All of the autopsied adults (n = 175; age > 18 years) with complete records, including weight and height data, were included. Pneumonitis was observed more frequently in malnourished individuals (59.1 percent) than in non-malnourished individuals (41.3 percent). This study showed that the percentage of pneumonitis among autopsied adults was high, in addition to an increased risk of pneumonitis among these individuals.


O objetivo deste estudo foi verificar se adultos subnutridos autopsiados teriam maior freqüência de pneumonite que adultos não-subnutridos. Todos os adultos autopsiados ((nº = 175); idade > 18 anos) com dados completos, incluindo peso e estatura, foram incluídos. Pneumonite foi observada com maior frequência em subnutridos (59,1 por cento) do que em não-subnutridos (41,3 por cento). Este estudo mostrou uma alta porcentagem de pneumonite entre os adultos autopsiados, além do aumento do risco de pneumonite entre estes.
