Pólipo endometrial metaplásico: hallazgo histeroscópico de enfermedad premaligna en mujeres jóvenes. Reporte de tres casos / Endometrial metaplastic polyps: findings of premalignant disease on histeroscopy in young women, a report of 3 cases

ANTECEDENTES: Los pólipos endometriales son sobrecrecimientos de la mucosa endometrial, una de las causas más comunes de hemorragia uterina anormal, pueden estar asociados con lesiones premalignas y malignas del endometrio. Existen características histeroscópicas que ayudan a diferenciar una lesión benigna o maligna. El pólipo metaplásico es un hallazgo histeroscópico caracterizado por superficies laminares e hiperqueratosis, con zonas blancas e hiperrefringentes. CASOS CLÍNICOS: Tres casos clínicos de pacientes menores de 40 años, con hemorragia uterina anormal donde el hallazgo histeroscópico común fue el pólipo metaplásico, hallazgo premaligno que se confirmó mediante el análisis patológico y la positividad del marcador de inmunohistoquímica p63. Caso 1. Paciente de 28 años, nulípara, obesa, con antecedente de síndrome de ovario poliquístico, con engrosamiento endometrial e histeroscopia, con pólipo con superficie hiperqueratósica, a manera de láminas irregulares, con excrecencias y lesiones exofíticas. Caso 2. Paciente de 25 años, con endometrio irregular engrosado e histeroscopia con hallazgo de pólipos transparentes, con cambios vasculares leves y superficie con zonas hiperrefringentes blanquecinas. Caso 3. Paciente de 38 años, con antecedente de síndrome de ovario poliquístico y obesidad. En la histeroscopia el endometrio se encontró hiperplásico, irregular, con cambios vasculares y pólipos con zonas superficiales hiperrefringentes, sólidas y blancas. CONCLUSIONES: En pacientes jóvenes, con hallazgo histeroscópico de pólipo metaplásico debe considerarse y descartar la enfermedad premaligna y maligna endometrial. El estudio debe completarse con marcadores de inmunohistoquímica (p63), específicos de la metaplasia escamosa.

Abstract BACKGROUND: Endometrial polyps are overgrowths of the endometrial mucosa, one of the most common causes of abnormal uterine bleeding and may be associated with premalignant and malignant endometrial lesions. There are hysteroscopic features that help differentiate a benign or malignant lesion. Metaplastic polyp is a hysteroscopic finding characterized by lamellar surfaces and hyperkeratosis, with white and hyperreflective areas. CLINICAL CASES: Three clinical cases of patients under 40 years of age, with abnormal uterine bleeding where the common hysteroscopic finding was metaplastic polyp, a premalignant finding that was confirmed by pathological analysis and positivity of the immunohistochemistry marker p63. Case 1. 28-year-old female, nulliparous, obese, with a history of polycystic ovary syndrome, with endometrial thickening and hysteroscopy, with polyp with hyperkeratotic surface, in the form of irregular sheets, with excrescences and exophytic lesions. Case 2. 25-year-old patient, with irregular thickened endometrium and hysteroscopy with finding of transparent polyps, with mild vascular changes and surface with whitish hyperrefringent areas. Case 3. 38-year-old patient with a history of polycystic ovary syndrome and obesity. At hysteroscopy the endometrium was found to be irregularly hyperplastic, with vascular changes and polyps with hyper-refringent, solid, white superficial areas. CONCLUSIONS: In young patients, with hysteroscopic finding of metaplastic polyp should be considered and premalignant and malignant endometrial disease should be ruled out. The study should be completed with immunohistochemical markers (p63), specific for squamous metaplasia.

Incidencia, mortalidad y supervivencia por cáncer de endometrio en Manizales, Colombia 2003-2017 / Incidence, mortality and survival of endometrial cancer in Manizales, Colombia 2003-2017

RESUMEN Objetivo. Estimar la incidencia, mortalidad y supervivencia a cinco años por carcinoma endometrial en Manizales, para el periodo 2003-2017. Materiales y métodos. Estudio observacional, retrospectivo, de base poblacional, con alcance descriptivo. Se ajustaron tasas de incidencia y mortalidad mediante el método directo usando la población mundial Segi como referencia. Se realizó seguimiento pasivo y activo de los casos hasta completar 60 meses o hasta la fecha de cierre de seguimiento. La supervivencia fue estimada mediante funciones de Kaplan-Meier y modelos de regresión de Cox. Resultados. Se observaron 210 casos incidentes en una población de 214 928 mujeres. La edad promedio al diagnóstico fue de 61 años. El tipo histológico más frecuente fue el endometrioide, bien diferenciado. La mayoría de las pacientes estaban afiliadas al régimen contributivo y pertenecían al nivel socioeconómico medio. La tasa de incidencia ajustada por edad fue de 5,7 casos nuevos por cada 100 000 mujeres-año. Se identificaron 75 defunciones con mayor mortalidad entre los 64 y los 79 años. La supervivencia global fue de 95,1% a los 12 meses y de 83,8% a los 60 meses. Se encontraron diferencias estadísticamente significativas en la supervivencia a favor de la histología epitelial, los estadios tempranos al momento del diagnóstico y la edad al diagnóstico menor a 60 años. Conclusiones. La mortalidad es similar a la reportada en otros países de la región. En Manizales, la sobrevida al cáncer de endometrio fue mayor en pacientes con diagnóstico temprano, con edad menor de 60 años y con histología endometrioide.

ABSTRACT Objective. To estimate the incidence, mortality and five-year survival of endometrial carcinoma in Manizales for the period 2003-2017. Materials and methods. Observational, retrospective, population-based study, descriptive in scope. Incidence and mortality rates were adjusted by the direct method using the Segi world population as reference. Passive and active follow-up of the cases was carried out until completing 60 months or until the follow-up closing date. Survival was estimated using Kaplan-Meier functions and Cox models. Results. 210 incident cases were observed in a population of 214.928 women. The average age at diagnosis was 61 years. The most frequent histological type was endometrioid, well differentiated. Most of the patients were affiliated to the contributory health insurance scheme and belonged to the middle socioeconomic level. The age-adjusted incidence rate was 5.7 new cases per 100,000 woman-years. Seventy-five deaths were identified, with greater mortality between 65-69 and 75-79 age groups. Overall survival was 95.1% at 12 months and 83.8% at 60 months. Statistically significant differences were found in survival in favor of epithelial histology, early stages at the time of diagnosis, and age at diagnosis less than 60 years. Conclusions. Manizales follows the global pattern of rise in the age-adjusted incidence rate. Mortality is like that reported in other countries in the region. In Manizales, endometrial cancer survival was higher in patients with early diagnosis, less than 60 years of age, and with endometrioid histology.

Carcinomas de ovário associados à endometriose: expressão de marcadores proteicos de terapia alvo e prognóstico / Endometriosis-associated ovarian carcinomas: expression of protein biomarkers associated to target therapies and prognosis

Resumo: Introdução: endometriose é uma doença benigna, capaz de progredir extensamente e gerar clones atípicos. Considerada precursora dos carcinomas de células claras (CCOC) e endometrióide (EOC) de ovário, atualmente chamados carcinomas de ovário associados à endometriose (EAOC). Objetivos: comparar o perfil epidemiológico, a associação com endometriose e a expressão de marcadores imuno-histoquímicos para ARID1A, VEGF, PD-L1 e PARP-1 em mulheres com CCOC e EOC, e sua correlação com a sobrevida livre de progressão (SLP) e sobrevida global (SG). Métodos: estudo de coorte reconstituída, com 50 casos incluídos de CCOC e EOC tratados no CAISM-UNICAMP entre 1995 até 2016, acompanhados até 02/2017. Microarranjos de tecido com amostras de CCOC, EOC e endometriose foram corados com anticorpos monoclonais contra ARID1A, e para os biomarcadores proteicos VEGF, PD-L1, PARP-1 através de imuno-histoquímica. A expressão de ARID1A foi classificada (0 a 100) conforme a porcentagem de células não coradas. A expressão de VEGF, PD-L1 e PARP-1 foi classificada (0 a 300) conforme a multiplicação da porcentagem de células coradas por um fator da intensidade de expressão (ausente=0; fraco=1; moderado=2; forte=3). Idade ao diagnóstico; menopausa; índice de massa corpórea (IMC); CA-125; diagnóstico de endometriose; datas do diagnóstico, da progressão, do óbito e da última consulta foram recuperados dos prontuários. Comparação entre grupos foi realizada através de testes T e de ?2. A SLP (diferença de tempo entre o diagnóstico e a data de progressão) e a SG (diferença de tempo entre o diagnóstico e o óbito ou data da última data de consulta) foi avaliada através de curvas de Kaplan-Meyer e teste de Log-Rank ou regressão de COX. Resultados: 23 mulheres com CCOC (46%), e 27 com EOC (54%) foram incluídas; 80% tinham endometriose associada, 42% eram nulíparas, 42% eram pré-menopausa e CA125 foi elevado em todos estádios (FIGO I-II= média 614.7Ui/mL; FIGO III-IV= media 2361.2Ui/mL). A média de idade ao diagnóstico foi 7 anos menor em mulheres com EOC do que naquelas com CCOC. O CCOC foi mais diagnosticado em estágios iniciais quando associado à endometriose (p=0,03). O prognóstico dos EOC e CCOC em estádios iniciais foi semelhante (p=0,96). Os CCOC não associado à endometriose tiveram menor SG (p=0,04). A expressão de todos os biomarcadores esteve presente nos EAOC e na endometriose. O aumento da expressão de VEGF entre endometriose e câncer foi significativo (p=0,0002). A hiperexpressão de PARP-1 correlacionou-se negativamente com a SLP (p=0,03) e SG (p=0,01) em estádios iniciais. Conclusão: Os CCOC e EOC são comumente diagnosticados em estádios iniciais (FIGO I-II= 68%) e estão frequentemente associados à endometriose (80% dos casos). Quando associados à endometriose, os CCOC foram mais diagnosticados em estádios iniciais e tiveram SG maior. Houve elevada porcentagem de células com ARID1A mutado nos EAOC (>40%). VEGF se expressou mais intensamente nos CCOC e EOC que na endometriose, já a expressão de PD-L1 e de PARP-1 foi similar. Apenas a hiperexpressão de PARP-1 reduziu significativamente a SLP e a SG nos CCOC e EOC nos estádios iniciais(AU)

Abstract: Introduction: Endometriosis is a benign disease, able to progress widely and generate atypical clones. It is a precursor of clear cell ovarian carcinomas (CCOC) and endometrioid ovarian carcinomas (EOCs), now called endometriosis-associated ovarian carcinomas (EAOC). Objectives: To compare the epidemiological profile, association with endometriosis and the expression of immunohistochemical markers for ARID1A, VEGF, PD-L1 and PARP-1 in women with CCOC and EOC, and its correlation with progression-free survival (PFS) and overall survival (OS). Methods: A reconstituted cohort study with 50 cases of CCOC and EOC included. Cases were treated at CAISM-UNICAMP between 1995 and 2016, followed up until 02/2017. Tissue microarrays with CCOC, EOC and endometriosis samples were stained with monoclonal antibodies against ARID1A, and for VEGF, PD-L1, PARP-1 biomarkers by immunohistochemistry. The expression of ARID1A was classified (0 to 100) according to the percentage of unstained cells. The expression of VEGF, PD-L1 and PARP-1 was classified (0 to 300) multiplying the percentage of stained cells by an intensity of expression factor (absent=0, weak=1, moderate=2, strong=3). Age at diagnosis; menopause; BMI (body mass index); CA-125 levels; diagnosis of endometriosis; date of diagnosis, date of progression, date of death and date of last consultation were retrieved from the medical records. Comparison between groups was performed through T and ?2 tests. The PFS (difference in time between diagnosis and progression date) and OS (difference in time between diagnosis and death or the last date of consultation) was assessed using Kaplan-Meyer curves and Log-Rank test or COX multivariate models. Results: twenty-three women with CCOC (46%), and 27 with EOC (54%) were included; 80% had associated endometriosis, 42% were nulliparous, 42% were premenopausal, and CA125 was elevated at all stages (FIGO I-II = mean 614.7Ui / mL; FIGO III-IV = mean 2361.2Ui / mL). The mean age at diagnosis was 7 years lower in women with EOC than in those with CCOC. CCOC when associated with endometriosis were more diagnosed at early stages (p=0.03). The prognosis of EOC and CCOC at early stages was similar (p=0.96). CCOCs not associated with endometriosis had shorter OS (p=0.04). Expression of all biomarkers was present in the EAOC and endometriosis. The increase in VEGF expression between endometriosis and cancer was significant (p=0.0002). The overexpression of PARP-1 correlated negatively with PFS (p=0.03) and OS (p=0.01) at FIGO I-II stages. Conclusion: The diagnosis of women with EOC was made earlier than in those with CCOC. CCOC and EOC are commonly diagnosed in early stages (FIGO I-II - 68%) and were associated with endometriosis (80% of cases). When associated with endometriosis, clear cell carcinomas are more likely diagnosed at early stages, and the association of endometriosis with CCOC improves OS. There was a high percentage of cells with mutated ARID1A gene in EAOC (> 40%). VEGF was expressed more intensely in CCOC and EOC than in endometriosis, whereas expression of PD-L1 and PARP-1 was similar. Only the overexpression of PARP-1 significantly reduced PFS and OS in CCOC and EOC at early stages(AU)

Características clínico-epidemiológicas y manejo del cáncer endometrial (2010-2013) / Clinical-epidemiological characteristics and management of endometrial cancer (2010-2013)

Introducción: el cáncer de endometrio ha incrementado su incidencia y se asocia a factores de riesgo presentes en muchas mujeres en la perimenopausia. El síntoma más común es el sangramiento y la modalidad de tratamiento más empleada es la cirugía. Objetivo: caracterizar el cáncer endometrial en el Hospital América Arias desde enero de 2010 hasta junio de 2013. Métodos: se realizó un estudio descriptivo en el Hospital América Arias, desde 1ro de enero de 2010 hasta el 30 de junio de 2013. Se incluyó el total las pacientes con sangramiento uterino anormal en la etapa peri y posmenopáusico a partir de 40 años de edad. Las pacientes con diagnóstico histopatológico de cáncer endometrial constituyeron la muestra (n= 49). Resultados: la edad promedio de las pacientes fue de 60,8 ± 9,9 años. Presentaban sobrepeso 30,6 por ciento, y 44,9 por ciento eran obesas. El examen histopatológico posquirúrgico muestra que la lesión estuvo limitada al endometrio en 14,3 por ciento de las pacientes; pero hubo invasión de los dos tercios externos del miometrio en 61,2 por ciento de ellas. La extensión al cuello y a los anejos uterinos fue de 38,8 por ciento y 22,4 por ciento respectivamente. Conclusiones: existe una tendencia a la aparición del adenocarcinoma endometrial en edades cada vez más avanzadas. Se asocia a factores de riesgo como obesidad, infertilidad y el uso de terapia hormonal de remplazo. Además de la cirugía, algunas pacientes requirieron tratamiento oncológico específico(AU)

Introduction: The incidence of endometrial cancer has increased and it is associated with risk factors present in many perimenopausewomen. The most common symptom is bleeding and the most widely used treatment modality is surgery. Objective: Characterize endometrial cancer at America Arias Hospital from January 2010 to June 2013. Methods: A descriptive study was conductedat America Arias Hospital, from 1 January 2010 to 30 June 2013. The total included over 40 year patients with abnormal uterine bleeding in perimenopausal and postmenopausal. Patients with histopathologic diagnosis of endometrial cancer constituted the sample (n= 49). Results: The mean age of patients was 60.8 ± 9.9 years. 30.6 percent were overweight and 44.9 percent were obese. Postoperative histopathologic examination shows that the lesion was limited to the endometrium in 14.3 percent of patients, but there was invasion of the two outer thirds of the myometrium in 61.2 percent. The extension cervix and adnexa was 38.8 percent and 22.4 percent, respectively. Conclusions: There is a tendency to the appearance of endometrial adenocarcinoma at increasingly advanced ages. It is associated with risk factors such as obesity, infertility, and the use of hormone replacement therapy. In addition to surgery, some patients required specific cancer treatment(AU)

Carcinoma de endometrio: revisión clínico-patológica de 6 años en relación con los factores pronósticos / Endometrial carcinoma: Clinico-pathological revision after 6 years, related to prognostic factors

Los carcinomas de endometrio se dividen en dos categorías mayores (I y II), según los datos clínico-patológicos y las alteraciones genéticas. Los de tipo I se asocian con hiperestimulación estrogénica, obesidad, tratamiento hormonal exógeno y reconocen como lesión precursora a la hiperplasia endometrial con desarrollo de carcinomas endometrioides (CE). Los de tipo II predominan en mujeres postmenopáusicas, de subtipos histológicos más frecuentes serosos y de células claras. El objetivo es realizar una revisión anátomo-clínica de los carcinomas de endometrio, estudiados en nuestra institución entre el periodo comprendido entre 1/01/2005 y 31/12/2010. Se realizó estudio retrospectivo y descriptivo de 234 casos de pacientes con diagnóstico de carcinoma endometrial. La edad promedio de las pacientes fue de 68,6 años. El motivo de la consulta en la mayoría de los casos fue metrorragia de la postmenopausia (91,2 por ciento). El factor de riesgo más frecuente fue hipertensión arterial (22 pacientes). El 67,5 por ciento de las pacientes tenían antecedentes de biopsia previa por videohisteroscopía realizada en nuestra institución, observándose concordancia diagnóstica en un 91 por ciento. Se clasificaron según la OMS en CE (79 por ciento), adenocarcinoma seroso (9 por ciento) y mixtos (12 por ciento). El grado histológico (GH) FIGO fue en el 86 por ciento tipo I (exclusión de carcinomas serosos) y el estadío más frecuente fue el I ( 65 por ciento). La metaplasia (Me) más frecuente observada en estas neoplasias fue la mucinosa (35 por ciento). Las mórulas se presentaron en 2 casos comprobados por IHQ con positividad para CD 10 y CDX-2 y negatividad para p63. Se evidenciaron cambios reactivos en el 26 por ciento. El patrón MELF (glándulas microquísticas, elongadas y fragmentadas), de infiltración en la pared miometrial, se identificó en 3 casos. El CE fue el tipo histológico más frecuente y su presentación (mayoritariamente en estadios tempranos de enfermedad), se asoció en un alto porcentaje con las metaplasias mucinosa y tubaria...

Endometrial carcinomas are divided into two major categories (I and II), according to clinicopathologic and genetic alterations. The type I is associated with estrogen hyperstimulation, obesity, exogenous hormonal treatment, and endometrial hyperplasia is recognized as a precursor lesion, with the consecuent endometroid carcinoma. The type II predominate in post-menopausal women, most common histologic subtypes are serous and clear cell. The aim is to review the anatomical and clinical characteristic of endometrial carcinomas, studied at our institution between 01/01/2005 and 31/12/2010. We performed a retrospective and descriptive study of 34 cases of patients with endometrial carcinoma. The average age was 68.6 years. The reason for consultation in most cases was post-menopausal's metrorrhagia (91.2 percent) Hypertension (22 patients) was the more prevalent risk fctor. 67.5 percent of the patients had a history of prior biopsy (histeroscopy) performed at our institution; diagnostic concordance was observed in 91 percent. Were classified according to the WHO in endometrioid carcinomas (79 percent), serous adenocarcinoma (9 percent) and mixed (12 percent). FIGO histologic grade was 86 percent in type I (excluding serous carcinomas) and stage I was the most frequent (65 percent). Mucinous metaplasia was the most frequently observed (35 percent). The morulae were presented in 2 cases (IHC positive for CDX-2 and CD10, and negative for p63). Reactive changes were in 26 percent. The MELF pattern of myometrial infiltration was identified in 3 cases. Endometrioid carcinoma was the most common histological type and presentation (mostly in early stages of disease). Was associated with a high percentaje of tubal and mucinous metaplasia (this would indicate malignancy attenuated). Not yet known meaning of morulae in carcinomas. While it must be record horns infiltration, the presence or not of the same does not change the treatment.

Adenocarcinoma endometrioide de ovário em parede abdominal / Endometrioid adenocarcinoma of ovary in abdominal wall

Introdução: A transformação maligna da endometriose pode ocorrer em 0,7-1% das pacientes e 78,7% desses casos ocorrem nos ovários. Este trabalho relatou o caso de um adenocarcinoma endometrioide de ovário em parede abdominal após dois partos cesarianos. Relato de caso: Paciente de 52 anos apresentava dor bem localizada em região de hipogástrio com presença de tumoração no mesmo local há 1 ano. A referida dor piorava no período menstrual. Relatou, ainda, aumento do número de ciclos menstruais (duas vezes ao mês). A realização de exames de imagem evidenciou formação nodular heterogênea medindo 45 x 45 mm, subjacente à cicatriz cirúrgica na extremidade direita (pfannestiel), com ausência de linfoadenopatias. Foi realizada a exérese do tumor da parede abdominal, que revelou, após exame anatomopatológico, ser um adenocarcinoma endometrioide de ovário. Discussão: A manipulação cirúrgica da cavidade pélvica pode ser considerada um fator de risco no desenvolvimento da endometriose extragonadal. Além disso, o hiperestrogenismo, seja endógeno, seja exógeno, tem sido considerado como um fator de risco no desenvolvimento do câncer originado da endometriose. A malignização extragonadal da endometriose deve ser considerada como um diagnóstico diferencial em qualquer mulher com massa em parede abdominal, dor pélvica e/ou abdominal, uso de terapia de reposição hormonal, histórico de manipulação cirúrgica da cavidade pélvica e sangramentos vaginais.

Introduction: The malignant transformation of endometriosis can occur in 0.7-1% of the patients and 78.7% of these cases occur in the ovaries. This paper reported a case of endometrioid adenocarcinoma of ovary in the abdominal wall after two cesarean deliveries. Case report: A 52-year patient presented well-localized pain at the hypogastrium region where a tumor has been present for 1 year. The related pain worsened during menstruation. She also related increase in the number of menstrual cycles (twice a month). The performance of imaging tests revealed heterogeneous nodular formation measuring 45 x 45 mm, behind the surgical scar on the right end (pfannestiel), with absence of lymphadenopathies. The excision of the tumor from the abdominal wall was performed and revealed, after anatomopathological examination, to be an endometriod adenocarcinoma of ovary. Discussion: The surgical manipulation of the pelvic cavity can be considered a risk factor in the development of extra-gonadal endometriosis. Moreover, the hyper-estrogenic, either endogenous or exogenous, has been considered a risk factor in cancer development originated from endometriosis. The extra-gonadal malignancy of endometriosis should be considered as a differential diagnostic in any woman with mass in the abdominal wall, with pelvic and/or abdominal pain, hormonal replacement therapy, history of surgical manipulation of the pelvic cavity and vaginal bleeding.

Tumor endometrioide borderline de ovário em adolescente: relato de caso / Borderline ovarian endometrioid tumor in adolescent: case report and review of the literature

Os tumores endometrioides malignos ovarianos são neoplasias epiteliais raras em pacientes jovens. Enquanto os carcinomas endometrioides ovarianos acometem mulheres na quinta e na sexta décadas de vida, os tumores borderline acometem mulheres em uma faixa etária mais ampla (de 22 a 77 anos). Descreveremos a seguir um caso raro de tumor endometrioide borderline ocorrendo em paciente de 16 anos. Desde que tumores do saco vitelino (TSV) e de Sertoli-Leydig (TCSL) podem mimetizar morfologicamente tumor endometrioide, o uso da imuno-histoquímica, além dos aspectos morfológicos, foi fundamental para estabelecer o diagnóstico diferencial entre essas condições.

Malignant endometrioid ovarian tumors are rare epithelial neoplasias among young patients. Whereas endometrioid ovarian carcinomas are more common among women in their fifth and sixth decades of life, borderline endometrioid tumors affect 22 to 77 year-old women. The present study reports a rare case of borderline endometrioid tumor in a 16 year-old patient. Since yolk sac and Sertoli-Leydig cell tumor may morphologically mimic endometrioid tumor, both the use of immunohistochemistry and morphological aspects were essential to establish the differential diagnosis.
