Doença trofoblástica gestacional: correlação ßhCG sérico quantitativo, ultrassonografia e anatomopatologia em serviço de obstetrícia do Ceará / Gestational trophoblastic disease: ßhCG quantitative serum correlation, ultrasonography and pathology in obstetrics service in Ceará

Doença trofoblástica gestacional (DTG) é uma anomalia que engloba formas clínicas benignas (mola hidatiforme completa e parcial) e malignas (mola invasora, coriocarcinoma, tumor trofoblástico do sítio placentário e tumor trofoblástico epitelioide). O objetivo deste estudo é realizar levantamento epidemiológico retrospectivo de prontuários de 40 pacientes internadas entre abril de 2014 e fevereiro de 2016 com hipótese diagnóstica de DTG atendidas no Hospital Regional Norte/ Centro de Apoio à Saúde Reprodutiva da Mulher em Sobral, no Ceará, traçando o perfil de cada paciente (idade, paridade), além de fazer correlação dos parâmetros clínicos, laboratoriais e anatomopatológico. Entre as pacientes que obtiveram o diagnóstico de DTG, observou-se que em torno de 93,33% possuíam exame ultrassonográfico evidenciando possível mola hidatiforme; o anatomopatológico confirmou doença trofoblástica em aproximadamente 52,5% da população estudada. Este estudo é inédito, por ser o primeiro a realizar um levantamento de dados em pacientes com DTG na cidade de Sobral.(AU)

Gestational trophoblastic disease (GTD) is an anomaly that encompasses benign clinical forms (complete and partial hydatidiform mole) and malignant (invasive mole, choriocarcinoma, placental site trophoblastic tumor and epithelioid trophoblastic tumor). The objective of this study was to carry out a retrospective epidemiological survey of medical records of 40 hospitalized patients between April 2014 and February 2016 with diagnostic hypothesis of GTD attended at the Regional Hospital Norte/Center for Support to Women's Reproductive Health in Sobral, Ceará, drawing the profile of each patient (age, parity), in addition to correlating the clinical, laboratory and anatomopathological parameters. Among the patients who had the diagnosis of GTD, it was observed that about 93.33% had ultrasonographic examination evidencing a possible hydatidiform mole; the anatomopathological confirmed trophoblastic disease in about 52.5% of the study population. This study is unprecedented because it is the first to perform a data collection in patients with GTD in the city of Sobral.(AU)

Mola hidatiforme parcial del segundo trimestre / Second trimester partial hydatidiform mole

La mola hidatiforme coexistente con un feto vivo es una entidad infrecuente que se caracteriza por la degeneración hidrópica de las vellosidades coriales, hiperplasia del trofoblasto y evidencia macroscópica de un feto. El objetivo del trabajo fue describir el caso clínico de una paciente con diagnóstico de mola parcial y edad gestacional de 23 semanas. Presentamos una paciente de 31 años remitida de consulta de perinatología con 22,5 semanas de gestación, tensión arterial elevada, signo de más y ecografía con 20 semanas que describe placenta con lagos venosos; con antecedentes de alfafetoproteína elevada. En el hospital empeoró su estado con una preeclampsia agravada, y con ecografía evolutiva que describe placenta de 71 mm, con múltiples lagos venosos. Se plantea posible enfermedad trofoblástica y se discute para interrupción del embarazo. Se realizó microcesárea, se obtiene feto muerto femenino de 600 gramos, con placenta de 400 gramos con múltiples vesículas que recuerdan la mola parcial, diagnóstico que se confirma posteriormente con estudio histopatológico. En la mola parcial, el embrión rara vez sobrevive hasta el segundo trimestre. Si no se realizan pruebas citogenéticas, posiblemente no se diagnostiquen porque los cambios histológicos suelen ser sutiles. La clínica, la fracción beta de la gonadotropina coriónica y el estudio de la placenta, el feto o ambos, son los que permitirán realizar el diagnóstico definitivo para determinar el seguimiento y disminuir las complicaciones(AU)

The hydatidiform mole coexisting with a living fetus is a rare entity that is characterized by hydropic degeneration of the chorionic villi, hyperplasia of the trophoblast and macroscopic evidence of a fetus. The objective of the study was to describe the clinical case of a patient with a diagnosis of partial mole and gestational age of 23 weeks. We present a 31-year-old patient referred for perinatology consultation with 22.5 weeks of gestation, high blood pressure, plus sign and ultrasound with 20 weeks describing placenta with venous lakes; and history of high alpha-fetoprotein. In the hospital, her condition worsened with aggravated preeclampsia, and with an evolving ultrasound, that describes a 71 mm placenta with multiple venous lakes. Possible trophoblastic disease arises and is discussed for termination of pregnancy. Micro-cesarean surgery was performed, a female fetus weighing 600 grams was obtained, a placenta of 400 grams with multiple vesicles that resemble partial mole. This diagnosis is later confirmed with histopathological study. In partial mole, the embryo rarely survives until the second trimester. If cytogenetic tests are not performed, they may not be diagnosed because the histological changes are usually subtle. The clinic, the beta fraction of the chorionic gonadotropin and the study of the placenta, the fetus or both, are the ones that will make the definitive diagnosis to determine the follow-up and decrease the complications(AU)

Mola invasiva / Invasive mole

La mola invasiva es poco frecuente y se caracteriza por la excesiva proliferación trofoblástica y penetración del trofoblasto dentro del miometrio, pero sin tendencia hacia la diseminación metastásica. El objetivo del trabajo es presentar un caso diagnosticado de neoplasia trofoblástica gestacional, tipo mola invasiva. Se realizaron estudios complementarios como: ecografía transabdominal, determinaciones de la fracción beta de la gonadotropina coriónica humana y una biopsia endometrial por legrado uterino. El resultado fue embarazo molar. Al ingreso le fue administrado metotrexato sistémico 25 mg intramuscular y ácido folínico un ámpula intramuscular de 15 mg diariamente, ambos durante cinco días. Posteriormente, a los 20 días se realizó histerectomía total abdominal sin anexectomía. La evolución clínica fue por consulta externa. Además, se realizó: radiografía de tórax, ultrasonografía de pelvis, dosificación de gonadotropina coriónica humana en su fracción beta, hemograma completo, tiempo de coagulación, sangramiento y transaminasa glutámico pirúvica evolutivas. En el manejo de la mola invasiva el tratamiento médico combinado con el quirúrgico fue efectivo y bien tolerado por la paciente.

Invasive mole is an infrequent condition characterized by excessive trophoblastic proliferation and trophoblast penetration into the myometrium, without a tendency to metastatic dissemination. The purpose of the study is to present a case diagnosed with gestational trophoblastic neoplasia of the invasive mole type. The following complementary tests were performed: transabdominal echography, human chorionic gonadotropin beta subunit determinations, and endometrial biopsy by uterine curettage. The result was molar pregnancy. Upon admission the patient was administered systemic methotrexate 25 mg intramuscularly, as well as an intramuscular ampoule of folinic acid 15 mg daily, both during five days. Total abdominal hysterectomy without anexectomy was performed 20 days later. Clinical evolution was followed up on an outpatient basis. The following tests were also performed: chest radiography, pelvic ultrasonography, human chorionic gonadotropin beta dosage, complete blood count, clotting time, bleeding and evolutive glutamic-pyruvic transaminase. During management of the invasive mole, the combination of clinical and surgical treatments proved effective and was well assimilated by the patient.

Caracterización clínica de la enfermedad trofoblástica gestacional, Hospital Ginecobstétrico Ramón González Coro (2008-2012) / Clinical characterization of gestational trophoblastic disease in Ramón González Coro obstetric and gynaecological hospital in the 2008-2012 period

Introducción: numerosas investigaciones han estudiado la enfermedad trofoblástica gestacional, haciendo énfasis en la importancia de su diagnóstico y tratamiento precoz. Se indaga en sus características para disminuir las tasas de incidencia, recaídas y/o complicaciones. Objetivo: se propone determinar el comportamiento clínico de pacientes con Enfermedad trofoblástica gestacional. Métodos: se efectuó un estudio observacional descriptivo transversal, en el Hospital Ginecobstétrico Ramón González Coro. Se trabajó una muestra de 18 historias clínicas de pacientes diagnosticadas o con sospecha de la enfermedad trofoblástica gestacional, de cualquier edad y color de piel, dentro del universo de todas las pacientes atendidas en el periodo 2008-2012. Resultados: predominó como motivo de ingreso el sangramiento vaginal, y al examen físico el principal signo fue la salida de sangre por el orificio cervical externo. La mayoría de los casos obtenidos el 83,4 por ciento fueron pacientes con más de 24 años. Casi el total de la muestra un 94 por ciento presentó un útero aumentado de tamaño. En este estudio más de la mitad de los casos el 83 por ciento fueron por mola hidatiforme parcial. Conclusiones: este estudio caracteriza el comportamiento clínico de pacientes con Trofoblástica gestacional. Los resultados coinciden con lo observado en otros estudios analizados como apoyo para la valoración y discusión de los resultados. Esta dolencia se caracteriza por presentarse en mujeres mayores de 24 años, sin distinción en cuanto al color de la piel; los signos más significativos al examen ginecológico son el sangramiento vaginal y la salida de sangre por el orificio cervical externo(AU)

Introduction: numerous research works have studied gestational trophoblastic disease; making emphasis on the importance of early diagnosis and treatment and have dealt with its characteristics in order to reduce incidence, relapse and/or complication rates Objective: to determine the clinical behavior of patients with gestational trophoblastic disease. Methods: observational descriptive and cross-sectional study was conducted in Ramón González Coro in obstetric and gynecological hospital. The sample was made up of 18 medical records of patients diagnosed with or suspected of gestational trophoblastic disease, regardless of their age and race, within the universe of all patients seen in the period of 2008 through 2012. Results: the main reasons for admission to hospital were vaginal bleeding, and the main sign in physical examination was blood outflow through the external cervical orifice. Most cases (83.4 percent) were over 24 years-old. Almost all the patients (94 percent) presented with augmented uterus. In this study, 83 percent of cases were caused byr partial hydatid form mole. Conclusions: this study characterizes the clinical behavior of patients with gestational trophoblastic disease. The results are consistent with those observed in other studies as a support for evaluation and discussion of the results. This condition is characterized by occurring in women over 24 years of age, regardless of race, and its most significant signs on gynecological examination are vaginal bleeding and blood outflow from the external os(AU)

Gestational trophoblastic disease in 2005.

Gestational trophoblastic diseases are still problematic in our practice. Event the incidence is in generally decreasing. And the development of Medicine in this decade can elucidate some parts of pathophysiology at cellular and molecular levels. However, malignant changes still can not be prevented. Approximately 20% of patients will develop malignant sequelae requiring administration of chemotherapy after evacuation of hydatidiform moles. Most patients with postmolar gestational trophoblastic disease will have non-metastatic molar proliferation or invasive moles, but gestational choriocarcinomas and metastatic disease can develop in this setting. Gestational choriocarcinoma occurs approximately 50% after term pregnancies, 25% after molar pregnancies, and the remainder after other gestational events. Although much rarer than hydatidiform moles or gestational choriocarcinomas, placental site trophoblastic tumors can develop after any type of pregnancy. For optimal management, practicing obstetrician-gynecologists should be able to diagnose and manage primary molar pregnancies, diagnose and stage malignant gestational trophoblastic neoplasia, and assess risk in women with malignant gestational trophoblastic neoplasia. This chapter views some points which may be useful for evidence-based practice in modern Medicine.
