ABSTRACT
Objetivo: Determinar asociaciones entre cáncer de mama específico por edades con tipo histológico y perfil inmunohistoquímico en pacientes de un hospital de nivel III Chiclayo-Perú, durante el periodo 2012-2015. Material y Métodos: Estudio retrospectivo transversal realizado en 271 pacientes diagnosticadas con carcinoma de mama a lo largo 4 años consecutivos. Se obtuvo información, trabajando con dos grupos etáreos (<55; >55) y aplicando una ficha de recolección de datos, partiendo de resultados de Anatomía patológica, en la cual se utilizaron criterios de inclusión/exclusión. Resultados: La edad promedio de las pacientes fue de 56,19 años, siendo la máxima 95 años, y la mínima 28. La edad promedio para el grupo menor a 55 años fue 44,77 años y para el grupo mayor a 55 años: 67,07; Ambos grupos mostraron características similares para su asociación para tipos histológicos (p = 0,353), como para perfiles Inmunohistoquímicos (p=0.757). Se obtuvo que el grupo etáreo <55 años, incluyo 123 casos (93,18%) con CDI (carcinoma ductal infiltrante), 3 (2,27%) con CLI (Carcinoma Lobulillar infiltrante), y tuvieron al subtipo molecular Luminal A como Luminal B con 63 (50,4%) y 23 (18,4%) respectivamente, para el grupo mayor a 55 años: CDI 123 (88,49%), CLI 8 (5,76%), Luminal A 73 (53,3%) y Luminal B 24 (17,5%). La frecuencia general mostró una tendencia bimodal así como los subtipos Luminal A, Luminal B, y Basal. Conclusiones: El carcinoma de mama más frecuente se dio en pacientes mayores a 55 años, con el tipo histológico de Carcinoma ductal Invasivo y el subtipo inmunohistoquímico Luminal A.
Objetive. The purpose of this study was to determine relationship between aged-specific histological types and immunohistochemical profiles in patients with breast carcinoma from a level III Hospital in Chiclayo- Peru, from 2012-2015. Material and Methods: A cross-sectional retrospective study was carried out in 271 patients diagnosed with breast carcinoma. Information was gathered, according two age-specific groups (<55; >55) and by applying a data collection sheet, based on clinical records from the Pathological Anatomy Service. Results: The average age was 56.19 years, maximum age was 95 years and minimum age was 28. The average age for the first group (<55 years) was 44.7 years and the second group (>55years) was 67 years. The two groups showed similar characteristics for their association of histological types (p = 0,353), as well as for immunohistochemical profiles (p=0.757; p =0.576). Patients under 55 years included 123 with IDC (93.18%), 3 with ILC (2.27%), 63 with molecular subtype Luminal A(50.4%) and 23 with Luminal B (18.4%). For the group over 55 years: 123 with IDC (88.49%), 8 with ILC (5.76%), 73 with Luminal A(53.3%) and 24 with Luminal B (17.5%). The overall frequency showed a bimodal trend as well as the molecular subtypes: Luminal A, Luminal B,and Basal-like. Conclusions: Older patients presented a higher frequency of breast carcinoma than young patients, with CDI tumor type and Luminal Amolecular subtype.
ABSTRACT
Oral cancer is a disease of high impact globally. It ranks as the sixth more frequent one among all types of cancer. In spite of being a widely known pathology and easy access to the diagnosis, the lack of epidemiological data reported in the last 10 years in Chile called attention to. At the global level, the World Health Organization (WHO) has developed a project called GLOBOCAN in order to collect epidemiological data of the global cancer, between its data, highlights the high incidence and high rate of mortality in the male sex, parameter that shows tendency to replicate in both America and Chile. In consequence to these data, a narrative review of the literature concerning the epidemiological profile of the different forms of oral cancer in the past 15 years was done. The diagnosis of oral cancer crosses transversely the Dental Science, forcing us to establish triads of work between oral and maxillofacial surgeons, pathologists and dentists of the various specialties, so as to allow a timely research, appropriate biopsies and histopathological studies finishes with the purpose of, on the one hand, obtain timely and accurate diagnostics, in addition, maintaining the epidemiological indicators...
El cáncer oral es una patología de alto impacto a nivel mundial, ocupando el sexto lugar más frecuente entre todos los tipos de cáncer. A pesar de unapatología ampliamente conocida y de fácil acceso al diagnóstico, llama la atención la falta de datos epidemiológicos reportados en los últimos 10 años en Chile. A nivelmundial, la Organización Mundial de Salud (OMS) ha desarrollado un proyecto denominado GLOBOCANcon el fin de recolectar datos epidemiológicos mundiales del cáncer, entre sus datos, destaca la gran incidencia y elevada tasa de mortalidad en el sexo masculino, parámetro que muestra tendencia a replicarse en tanto América como en Chile. En consecuencia a estos datos, se realizóuna revisión narrativa de la literatura, referente al perfil epidemiológico de las diferentes formas de cáncer oral enlos últimos 15 años. El diagnóstico del cáncer oral cruza de manera transversal a la Odontología, obligándonos a establecer triadas de trabajo entre cirujanos orales y maxilofaciales,patólogos y odontólogos de las diversas especialidades, para permitir así una oportuna pesquisa, biopsias adecuadas y estudios histopatológicos acabados con la finalidad de, por una parte, obtener diagnósticos oportunos y certeros, además, mantener actualizados los indicadores epidemiológicos...

OBJETIVO: Comparar as características clinicopatológicas de mulheres com carcinoma seroso e não seroso de ovário e identificar os fatores associados à sobrevida. MÉTODOS: Foram incluídas, neste estudo de coorte reconstituída, 152 mulheres com carcinoma de ovário, atendidas entre 1993 e 2008 e seguidas até 2010, nas quais o tipo histológico foi claramente estabelecido: 81 pacientes com carcinoma seroso e 71 pacientes com tumores não serosos (17 com carcinoma endometrioide, 44 com carcinoma mucinoso e 10 com carcinoma de células claras). Foram calculados os odds ratios (OR) brutos e os OR ajustados com os respectivos intervalos de confiança (IC95%) para as características clínicas e patológicas, comparando tumores serosos e não serosos. Foram calculados os Hazard Ratios (HR) com os respectivos IC95% em relação à sobrevida geral, para as variáveis clínicas e patológicas. RESULTADOS: Comparando os tipos seroso e não seroso, na análise univariada, os tumores serosos foram mais frequentes na pós-menopausa e eram preponderantemente carcinomas de alto grau histológico (G2 e G3), em estádios avançados, com CA125>250 U/mL e citologia peritoneal positiva. Após regressão múltipla, apenas o alto grau histológico se manteve associado com tumores serosos (OR ajustado 15,1; IC95% 2,9-77,9). Observamos 58 óbitos pela doença. O tipo histológico (seroso ou não seroso) não esteve associado com a sobrevida (HR 0,4; IC95% 0,1-1,1). Mulheres com idade de 50 anos ou menos (HR 0,4; IC95% 0,1-0,9) e aquelas que estavam em menacme (HR 0,3; IC95% 0,1-0,9) tiveram maior sobrevida quando comparadas, respectivamente, àquelas com idade acima de 50 anos e na menopausa. Carcinomas de alto grau histológico (G2 e G3) (p<0,01), estádio II a IV (p<0,008) e citologia peritoneal positiva (p<0,001) estiveram significativamente relacionados com pior prognóstico. O nível sérico de CA125 e a presença de ascite não se relacionaram com a sobrevida. A sobrevida foi menor quando a doença foi diagnosticada em estágios II a IV em comparação àquela das mulheres diagnosticadas no estádio I (log-rank p<0,01) independentemente do tipo histológico (seroso ou não seroso). CONCLUSÕES: A proporção de carcinomas de alto grau histológico (G2 ou G3) foi significativamente maior entre os carcinomas serosos comparados com não serosos. O tipo histológico seroso ou não seroso não esteve associado à sobrevida total.
PURPOSE: To compare the clinical-pathological features of women with serous and non-serous ovarian tumors and to identify the factors associated with survival. METHODS: In this reconstructed cohort study, 152 women with ovarian carcinoma, who attended medical consultations between 1993 and 2008 and who were followed-up until 2010 were included. The histological type was clearly established for all women: 81 serous carcinomas and 71 non-serous tumors (17 endometrioid, 44 mucinous and 10 clear cell carcinomas). The crude and adjusted odds ratios (OR), with the respective 95% confidence intervals (95%CI), were calculated for the clinical and pathological features, comparing serous and non-serous histological types. The Hazard Ratios (HR) with 95%CI was calculated for overall survival, considering the clinical and pathological features. RESULTS: Comparison of serous to non-serous tumor types by univariate analysis revealed that serous tumors were more frequently found in postmenopausal women, and were predominantly high histological grade (G2 and G3), advanced stage, with CA125>250 U/mL, and with positive peritoneal cytology. After multivariate regression, the only association remaining was that of high histological grade with serous tumors (adjusted OR 15.1; 95%CI 2.9-77.9). We observed 58 deaths from the disease. There was no difference in overall survival between women with serous carcinoma and women with non-serous carcinoma (HR 0.4; 95%CI 0.1 - 1.1). It was observed that women aged 50 years or less (HR 0.4; 95%CI 0.1-0.9) and those who were in menacne (HR 0.3; 95%CI 0.1-0.9) had a longer survival compared respectively to those above 50 years of age and menopaused. High histological grade (G2 and G3) (p<0.01), stages II-IV (p<0.008) and positive cytology (p<0.001) were significantly associated with worse prognosis. CA125 and the presence of ascites did not correlate with survival. Survival was poor when the disease was diagnosed in stages II to IV and compared to stage I (log-rank p<0.01) regardless of histological type (serous and non-serous). CONCLUSIONS: The proportion of high histological grade (G2 and G3) was significantly higher among serous than non-serous carcinomas. Serous and non-serous histological types were not related to overall survival.
