RESUMO

BACKGROUND: Patients with gestational trophoblastic neoplasia who have an International Federation of Gynaecology and Obstetrics (FIGO) risk score of 5 or 6 usually receive non-toxic single-agent chemotherapy as a first-line treatment. Previous studies suggest that only a third of patients have complete remission, with the remaining patients requiring toxic multiagent chemotherapy to attain remission. As stratification factors are unknown, some centres offer multiagent therapy upfront, resulting in overtreatment of many patients. We aimed to identify predictive factors for resistance to single-agent therapy to inform clinicians on which patients presenting with a FIGO score of 5 or 6 are likely to benefit from upfront multiagent chemotherapy. METHODS: We did a multicentre, retrospective, cohort study of patients with gestational trophoblastic neoplasia presenting with a FIGO score of 5 or 6, who received treatment at three gestational trophoblastic neoplasia reference centres in the UK, Brazil, and the USA between Jan 1, 1964, and Dec 31, 2018. All patients who had been followed up for at least 12 months after remission were included. Patients were excluded if they had received a non-standard single-agent treatment (eg, etoposide); had been given a previously established first-line multiagent chemotherapy regimen; or had incomplete data for our analyses. Patient data were retrieved from medical records. The primary outcome was the incidence of chemoresistance after first-line or second-line single-agent chemotherapy. Variables associated with chemoresistance to single-agent therapies were identified by logistic regression analysis. In patient subgroups defined by choriocarcinoma histology and metastatic disease status, we did bootstrap modelling to define thresholds of pretreatment human chorionic gonadotropin concentrations and identify groups of patients with a greater than 80% risk (ie, a positive predictive value [PPV] of 0·8) of resistance to single-agent chemotherapy. FINDINGS: Of 5025 patients with low-risk gestational trophoblastic neoplasia, we identified 431 patients with gestational trophoblastic neoplasia presenting with a FIGO risk score of 5 or 6. All patients were followed up for a minimum of 2 years. 141 (40%) of 351 patients developed resistance to single-agent treatments and required multiagent chemotherapy to achieve remission. Univariable and multivariable logistic regression revealed metastatic disease status (multivariable logistic regression analysis, odds ratio [OR] 1·9 [95% CI 1·1-3·2], p=0·018), choriocarcinoma histology (3·7 [1·9-7·4], p=0·0002), and pretreatment human chorionic gonadotropin concentration (2·8 [1·9-4·1], p<0·0001) as significant predictors of resistance to single-agent therapies. In patients with no metastatic disease and without choriocarcinoma, a pretreatment human chorionic gonadotropin concentration of 411 000 IU/L or higher yielded a PPV of 0·8, whereas in patients with either metastases or choriocarcinoma, a pretreatment human chorionic gonadotropin concentration of 149 000 IU/L or higher yielded the same PPV for resistance to single-agent therapy. INTERPRETATION: Approximately 60% of women with gestational trophoblastic neoplasia presenting with a FIGO risk score of 5 or 6 achieve remission with single-agent therapy; almost all remaining patients have complete remission with subsequent multiagent chemotherapy. Primary multiagent chemotherapy should only be given to patients with metastatic disease and choriocarcinoma, regardless of pretreatment human chorionic gonadotropin concentration, or to those defined by our new predictors.

RESUMO

BACKGROUND: South America has a higher incidence of gestational trophoblastic disease than North America or Europe, but whether this impacts chemotherapy outcomes is unclear. The purpose of this study was to evaluate outcomes among women with high-risk gestational trophoblastic neoplasia (GTN) treated at trophoblastic disease centers in developing South American countries. METHODS: This retrospective cohort study included patients with high-risk GTN treated in three trophoblastic disease centers in South America (Botucatu and Rio de Janeiro, Brazil, and Buenos Aires, Argentina) from January 1990 to December 2014. Data evaluated included demographics, clinical presentation, FIGO stage, WHO prognostic risk score, and treatment-related information. The primary treatment outcome was complete sustained remission by 18 months following completion of therapy or death. RESULTS: Among 1264 patients with GTN, 191 (15.1%) patients had high-risk GTN and 147 were eligible for the study. Complete sustained remission was ultimately achieved in 87.1% of cases overall, including 68.4% of ultra high-risk GTN (score ≥12). Early death (within 4 weeks of initiating therapy) was significantly associated with ultra high-risk GTN, occurring in 13.8% of these patients (p=0.003). By Cox's proportional hazards regression, factors most strongly related to death were non-molar antecedent pregnancy (RR 4.35, 95% CI 1.71 to 11.05), presence of liver, brain, or kidney metastases (RR 4.99, 95% CI 1.96 to 12.71), FIGO stage (RR 3.14, 95% CI 1.52 to 6.53), and an ultra-high-risk prognostic risk score (RR 7.86, 95% CI 2.99 to 20.71). Median follow-up after completion of chemotherapy was 4 years. Among patients followed to that timepoint, the probability of survival was 90% for patients with high-risk GTN (score 7-11) and 60% for patients with ultra-high-risk GTN (score ≥12). CONCLUSION: Trophoblastic disease centers in developing South American countries have achieved high remission rates in high-risk GTN, but early deaths remain an important problem, particularly in ultra-high-risk GTN.

RESUMO

OBJECTIVE: The aim of the study was to evaluate potential changes in the clinical, diagnostic, and therapeutic parameters of complete hydatidiform mole in the last 25 years in Brazil. METHODS: A retrospective cohort study was conducted involving the analysis of 2163 medical records of patients diagnosed with complete hydatidiform mole who received treatment at the Rio de Janeiro Reference Center for Gestational Trophoblastic Disease between January 1988 and December 2012. For the statistical analysis of the natural history of the patients with complete molar pregnancies, time series were evaluated using the Cox-Stuart test and adjusted by linear regression models. RESULTS: A downward linear temporal trend was observed for gestational age of complete hydatidiform mole at diagnosis, which is also reflected in the reduced occurrence of vaginal bleeding, hyperemesis and pre-eclampsia. We also observed an increase in the use of uterine vacuum aspiration to treat molar pregnancy. Although the duration of postmolar follow-up was found to decline, this was not accompanied by any alteration in the time to remission of the disease or its progression to gestational trophoblastic neoplasia. CONCLUSIONS: Early diagnosis of complete hydatidiform mole has altered the natural history of molar pregnancy, especially with a reduction in classical clinical symptoms. However, early diagnosis has not resulted in a reduction in the development of gestational trophoblastic neoplasia, a dilemma that still challenges professionals working with gestational trophoblastic disease.

RESUMO

OBJECTIVE: Understand and explore the childbirth experiences of pregnant women living with HIV (PWLWHIV). With the advent of several measures to decrease the intrapartum HIV infection and a strong emphasis on the humanization of childbirth, there is a growing focus on providing positive childbirth experiences for pregnant women. Indeed, a positive childbirth experience is even more important in the group of pregnant women living with HIV (PWLWHIV) as it plays a pivotal role in enhancing the mother's adherence to her postpartum treatment and the newborn's engagement in Infectious Disease services. METHODOLOGY: A scoping review was conducted. Searches were performed on databases, such as MEDLINE, PUBMED, WEB OF SCIENCE and Cochrane Library, using the following keywords: childbirth, birth, parturition, HIV, humaniz*, perceived safety, experience, maternal satisfaction, healthcare professional and midwi*. Articles meeting pre-established criteria were selected within the timeframe of 2013 to 2023 for inclusion in the review. RESULTS: Out of a total of 2,340,391 articles, 4 were chosen based on our defined criteria. Three primary themes emerged from the selected articles: the assessment of childbirth experience quality, vulnerability and autonomy. CONCLUSIONS: The four studies identified had a small sample size and were not adequately conducted with a specific focus on studying the childbirth experience of pregnant women living with HIV (PWLWHIV). This scoping review revealed a gap in the existing literature, indicating a need for further research and clarification in the identified area.

RESUMO

Background: Knowledge regarding the risks associated with Zika virus (ZIKV) infections in pregnancy has relied on individual studies with relatively small sample sizes and variable risk estimates of adverse outcomes, or on surveillance or routinely collected data. Using data from the Zika Brazilian Cohorts Consortium, this study aims, to estimate the risk of adverse outcomes among offspring of women with RT-PCR-confirmed ZIKV infection during pregnancy and to explore heterogeneity between studies. Methods: We performed an individual participant data meta-analysis of the offspring of 1548 pregnant women from 13 studies, using one and two-stage meta-analyses to estimate the absolute risks. Findings: Of the 1548 ZIKV-exposed pregnancies, the risk of miscarriage was 0.9%, while the risk of stillbirth was 0.3%. Among the pregnancies with liveborn children, the risk of prematurity was 10,5%, the risk of low birth weight was 7.7, and the risk of small for gestational age (SGA) was 16.2%. For other abnormalities, the absolute risks were: 2.6% for microcephaly at birth or first evaluation, 4.0% for microcephaly at any time during follow-up, 7.9% for neuroimaging abnormalities, 18.7% for functional neurological abnormalities, 4.0% for ophthalmic abnormalities, 6.4% for auditory abnormalities, 0.6% for arthrogryposis, and 1.5% for dysphagia. This risk was similar in all sites studied and in different socioeconomic conditions, indicating that there are not likely to be other factors modifying this association. Interpretation: This study based on prospectively collected data generates the most robust evidence to date on the risks of congenital ZIKV infections over the early life course. Overall, approximately one-third of liveborn children with prenatal ZIKV exposure presented with at least one abnormality compatible with congenital infection, while the risk to present with at least two abnormalities in combination was less than 1.0%.

RESUMO

OBJECTIVE: To relate preevacuation platelet count and leukogram findings, especially neutrophil/lymphocyte ratios (NLR) and platelet/lymphocyte ratios with the occurrence of gestational trophoblastic neoplasia (GTN) after complete hydatidiform mole (CHM) among Brazilian women. METHODS: Retrospective cohort study of patients with CHM followed at Rio de Janeiro Federal University, from January/2015-December/2020. Before molar evacuation, all patients underwent a medical evaluation, complete blood count and hCG measurement, in addition to other routine preoperative tests. The primary outcome was the occurrence of postmolar GTN. RESULTS: From 827 cases of CHM treated initially at the Reference Center, 696 (84.15%) had spontaneous remission and 131 (15.85%) developed postmolar GTN. Using optimal cut-offs from receiver operating characteristic curves and multivariable logistic regression adjusted for the possible confounding variables of age and preevacuation hCG level (already known to be associated with the development of GTN) we found that ≥2 medical complications at presentation (aOR: 1.96, CI 95%: 1.29-2.98, p<0.001) and preevacuation hCG ≥100,000 IU/L (aOR: 2.16, CI 95%: 1.32-3.52, p<0.001) were significantly associated with postmolar GTN after CHM. However, no blood count profile findings were able to predict progression from CHM to GTN. CONCLUSION: Although blood count is a widely available test, being a low-cost test and mandatory before molar evacuation, and prognostic for outcome in other neoplasms, its findings were not able to predict the occurrence of GTN after CHM. In contrast, the occurrence of medical complications at presentation and higher preevacuation hCG levels were significantly associated with postmolar GTN and may be useful to guide individualized clinical decisions in post-molar follow-up and treatment of these patients.

RESUMO

The PIPA Project is a prospective birth cohort study based in Rio de Janeiro, Brazil, whose pilot study was carried out between October 2017 and August 2018. Arsenic (As), cadmium (Cd), lead (Pb), and mercury (Hg) concentrations were determined in maternal (n = 49) and umbilical cord blood (n = 46). The Denver Developmental Screening Test II (DDST-II) was applied in 50 six-month-old infants. Metals were detected in 100% of the mother and newborn samples above the limits of detection. Maternal blood lead concentrations were higher in premature newborns (GM: 5.72 µg/dL; p = 0.05). One-third of the infants (n = 17-35.4%) exhibited at least one fail in the neurodevelopment evaluation (fail group). Maternal blood arsenic concentrations were significantly (p = 0.03) higher in the "fail group" (GM: 11.85 µg/L) compared to infants who did not fail (not fail group) (GM: 8.47 µg/L). Maternal and umbilical cord blood arsenic concentrations were higher in all Denver Test's domains in the "fail group", albeit non-statistically significant, showing a tendency for the gross motor domain and maternal blood (p = 0.07). These findings indicate the need to further investigate the toxic effects of prenatal exposure to metals on infant neurodevelopment.

RESUMO

OBJECTIVE: The aim of this study was to collect and analyze data from different sources to have a general overview of COVID-19-related maternal deaths in Brazil, as well as to compare data with worldwide reports. STUDY DESIGN: We systematically searched data about COVID-19 maternal deaths from the Brazilian Ministry of Health surveillance system, State Departments of Health epidemiological reports, and media coverage. Data about timing of symptom onset and death (pregnancy or postpartum), gestational age, mode of birth, maternal age, comorbidities and/or risk factors, date of death, and place of death were retrieved when available. RESULTS: We identified 20 COVID-19-related maternal deaths, age range 20-43 years. Symptoms onset was reported as on pregnancy for 12 cases, postpartum for 3 cases, and during the cesarean section for 1 case (missing data for 4). In 16 cases, death occurred in the postpartum period. At least one comorbidity or risk factor was present in 11 cases (missing data for 4). Asthma was the most common risk factor (5/11). Ten cases occurred in the Northeast region, and nine cases occurred in the Southeast region (5 of them in São Paulo, the first epicenter of COVID-19 in the country). CONCLUSIONS: To the best of our knowledge, this is the largest available series of maternal deaths due to COVID-19. Barriers to access healthcare, differences in pandemic containment measures in the country and high prevalence of concomitant risk factors for COVID-19 severe disease may play a role in the observed disparity compared to worldwide reports on maternal outcomes.

RESUMO

Group B Streptococcus (GBS) is a leading cause of neonatal infections. The genitourinary and gastrointestinal tract of pregnant women are the main source of transmission to newborns. This work investigated the prevalence and characterized GBS from pregnant women in Rio de Janeiro, Brazil, comparing the periods before (January 2019 to March 2020; 521) and during (May 2020 to March 2021; 285) the COVID-19 pandemic. GBS was detected in 10.8% of anovaginal samples. Considering scenarios before and during the pandemic, GBS colonization rate significantly decreased (13.8% vs. 5.3%; p = 0.0001). No clinical and sociodemographic aspect was associated with GBS carriage (p > 0.05). A total of 80%, 13.8% and 4.6% GBS strains were non-susceptible to tetracycline, erythromycin and clindamycin, respectively. Serotype Ia was the most frequent (47.7%), followed by V (23.1%), II (18.4%), III (7.7%) and Ib (3.1%). An increasing trend of serotypes Ib and V, as well as of antimicrobial resistance rates, and a decreasing trend of serotypes II and III, were observed after the pandemic onset, albeit not statistically significant (p > 0.05). The reduction in GBS colonization rates and alterations in GBS serotypes and resistance profiles during the pandemic were not due to changes in the sociodemographic profile of the population. Considering that control and preventive measures related to the COVID-19 pandemic onset have impacted other infectious diseases, these results shed light on the need for the continuous surveillance of GBS among pregnant women in the post-pandemic era.

RESUMO

OBJECTIVE: Evaluate the prevalence and the regression rate of cytological alteration in pregnant patients below the recommended age by the Brazilian Guidelines for the Screening of Uterine Cervical Cancer Guideline in the prenatal service of Maternidade Escola da Universidade Federal do Rio de Janeiro. STUDY DESIGN: We included the cytopathological exams of all pregnant patients that attended on the outpatient from January 2010 to May 2016. For the identification of the pregnant women, the Management and Integrated System and the Uterine Cervical Cancer Information System of the institution were used. We performed X2 test. The level of significance was 0.05. RESULTS: The study totaled 5825 cytopathological exams, of which 1822 were from pregnant patients ≤ 24 years of age. Only 4.06 % (74/1822) of altered results were found (p < 0.05). The most frequent change was low-grade squamous intraepithelial lesion with a prevalence of 1.92 % (35/1822) whereas high-grade squamous intraepithelial lesion had 0.16 % (3/1822). The regression rate in pregnant patients ≤24 years of age was 34,32 %. CONCLUSION: There was a low prevalence of cytological abnormalities in pregnant patients ≤ 24 years, low frequency of high-grade squamous intraepithelial lesion among the altered cytologies and a high spontaneous regression rate, therefore screening is not recommended before the age determined by the Brazilian Guideline.

RESUMO

Gestational trophoblastic neoplasia (GTN) is a rare tumor that originates from pregnancy that includes invasive mole, choriocarcinoma (CCA), placental site trophoblastic tumor and epithelioid trophoblastic tumor (PSTT/ETT). GTN presents different degrees of proliferation, invasion and dissemination, but, if treated in reference centers, has high cure rates, even in multi-metastatic cases. The diagnosis of GTN following a hydatidiform molar pregnancy is made according to the International Federation of Gynecology and Obstetrics (FIGO) 2000 criteria: four or more plateaued human chorionic gonadotropin (hCG) concentrations over three weeks; rise in hCG for three consecutive weekly measurements over at least a period of 2 weeks or more; and an elevated but falling hCG concentrations six or more months after molar evacuation. However, the latter reason for treatment is no longer used by many centers. In addition, GTN is diagnosed with a pathological diagnosis of CCA or PSTT/ETT. For staging after a molar pregnancy, FIGO recommends pelvic-transvaginal Doppler ultrasound and chest X-ray. In cases of pulmonary metastases with more than 1 cm, the screening should be complemented with chest computed tomography and brain magnetic resonance image. Single agent chemotherapy, usually Methotrexate (MTX) or Actinomycin-D (Act-D), can cure about 70% of patients with FIGO/World Health Organization (WHO) prognosis risk score ≤ 6 (low risk), reserving multiple agent chemotherapy, such as EMA/CO (Etoposide, MTX, Act-D, Cyclophosphamide and Oncovin) for cases with FIGO/WHO prognosis risk score ≥ 7 (high risk) that is often metastatic. Best overall cure rates for low and high risk disease is close to 100% and > 95%, respectively. The management of PSTT/ETT differs and cure rates tend to be a bit lower. The early diagnosis of this disease and the appropriate treatment avoid maternal death, allow the healing and maintenance of the reproductive potential of these women.

RESUMO

OBJECTIVE: To evaluate uterine evacuation of patients with molar pregnancy, comparing manual with electric vacuum aspiration. METHODS: This is a retrospective cohort study of patients with molar pregnancy followed at the Rio de Janeiro Trophoblastic Disease Center from January 2007 to December 2016. The individual primary study outcomes were incomplete uterine evacuation, uterine perforation, development of uterine synechia, and development of postmolar gestational trophoblastic neoplasia. Secondary endpoints were other features of the perioperative outcomes (operative time, rate of transfusion, hemoglobin change, length of stay) and the clinical course of neoplasia (Prognostic Risk Score, presence of metastases, time to remission, and need for multiagent chemotherapy). RESULTS: Among 1,727 patients with molar pregnancy, 1,206 underwent electric vacuum aspiration and 521 underwent manual vacuum aspiration. After human chorionic gonadotropin normalization, patients with benign molar pregnancy were followed for 6 months and patients treated for gestational trophoblastic neoplasia were followed for 12 months. Baseline risk factors for gestational trophoblastic neoplasia and demographic features were similar between the treatment groups. Uterine synechia developed less frequently after manual vacuum aspiration than after electric vacuum aspiration, 6 of 521 vs 63 of 1,206 (adjusted odds ratio [OR] 0.21, 95% CI 0.09-0.49), despite no differences in the occurrence of incomplete uterine evacuation, 65 of 521 vs 161 of 1,206 (adjusted OR 0.93, 95% CI 0.69-1.27), development of postmolar gestational trophoblastic neoplasia, 90 of 521 vs 171 of 1,206 (adjusted OR 1.26, 95% CI 0.96-1.67), or the need for multiagent chemotherapy, 22 of 521 vs 41 of 1,206 (adjusted OR 0.81, 95% CI 0.73-1.28). CONCLUSION: Manual vacuum aspiration appears to be similar to electric vacuum aspiration for treatment of molar pregnancy and may be associated with less development of uterine synechia.

RESUMO

Abstract Objective To evaluate the efficacy of immunotherapy for GTN treatment after methotrexate-resistance or in cases of multiresistant disease, through a systematic review, as well as to present the first 4 Brazilian cases of immunotherapy for GTN treatment. Methods Three independent researchers searched five electronic databases (EMBASE, LILACS, Medline, CENTRAL and Web of Science), for relevant articles up to February/2023 (PROSPERO CRD42023401453). The quality assessment was performed using the Newcastle Ottawa scale for case series and case reports. The primary outcome of this study was the occurrence of complete remission. The presentation of the case reports was approved by the Institutional Review Board. Results Of the 4 cases presented, the first was a low-risk GTN with methotrexate resistance unsuccessfully treated with avelumab, which achieved remission with sequential multiagent chemotherapy. The remaining 3 cases were high-risk multiagent-resistant GTN that were successfully treated with pembrolizumab, among which there were two subsequent gestations, one of them with normal pregnancy and healthy conceptus. Regarding the systematic review, 12 studies were included, only one of them on avelumab, showing a 46.7% complete remission rate. The remaining 11 studies were on pembrolizumab, showing an 86.7% complete remission rate, regardless of tumor histology. Both immunotherapies showed good tolerability, with two healthy pregnancies being recorded: one after avelumb and another after pembrolizumab. Conclusion Immunotherapy showed effectiveness for GTN treatment and may be especially useful in cases of high-risk disease, where pembrolizumab achieves a high therapeutic response, regardless of the histological type, and despite prior chemoresistance to multiple lines of treatment.

RESUMO

OBJECTIVES:: Doppler ultrasonography can be used to assess neoangiogenesis, a characteristic feature of postmolar gestational trophoblastic neoplasia. However, there is limited information on whether uterine artery Doppler flow velocimetry parameters can predict gestational trophoblastic neoplasia following a complete hydatidiform mole. The purpose of this study was as follows: 1) to compare uterine blood flow before and after complete mole evacuation between women who developed postmolar gestational trophoblastic neoplasia and those who achieved spontaneous remission, 2) to assess the usefulness of uterine Doppler parameters as predictors of postmolar gestational trophoblastic neoplasia and to determine the best parameters and cutoff values for predicting postmolar gestational trophoblastic neoplasia. METHODS:: This prospective cohort study included 246 patients with a complete mole who were treated at three different trophoblastic diseases centers between 2013 and 2014. The pulsatility index, resistivity index, and systolic/diastolic ratio were measured by Doppler flow velocimetry before and 4-6 weeks after molar evacuation. Statistical analysis was performed using Wilcoxon's test, logistic regression, and ROC analysis. RESULTS:: No differences in pre- and post-evacuation Doppler measurements were observed in patients who developed postmolar gestational trophoblastic neoplasia. In those with spontaneous remission, the pulsatility index and systolic/diastolic ratio were increased after evacuation. The pre- and post-evacuation pulsatility indices were significantly lower in patients with gestational trophoblastic neoplasia (odds ratio of 13.9-30.5). A pre-evacuation pulsatility index ≤1.38 (77% sensitivity and 82% specificity) and post-evacuation pulsatility index ≤1.77 (79% sensitivity and 86% specificity) were significantly predictive of gestational trophoblastic neoplasia. CONCLUSIONS:: Uterine Doppler flow velocimetry measurements, particularly pre- and post-molar evacuation pulsatility indices, can be useful for predicting postmolar gestational trophoblastic neoplasia.

RESUMO

A epilepsia, doença cerebral caracterizada pela predisposição à geração de crises epilépticas, representa a patologia neurológica grave mais frequente na gravidez. Quando não acompanhada corretamente, possui um acentuado nível de morbimortalidade materno-fetal, sendo especialmente relacionada a riscos de convulsão materna na gestação e malformações fetais. Este artigo discute o acompanhamento da gestante epiléptica, trazendo recomendações de cuidados no período pré-concepcional, manejo durante o pré-natal, condução do trabalho de parto, peculiaridades no puerpério e tratamento de crises convulsivas, quando necessário. Serão abordados tanto aspectos de tratamento farmacológico quanto de monitoramento e orientações gerais, com o objetivo de contribuir para um suporte mais abrangente e adequado a esse grupo mais vulnerável de pacientes sob o cuidado do médico ginecologista-obstetra e neurologista.(AU)


Epilepsy, which is a brain disease defined for a greater predisposition for epileptic crisis, represents the most frequent neurological pathology during pregnancy. Without proper monitoring it is related to high morbidity and mortality to both mother and baby, especially due to the risks of mother seizure during pregnancy and fetus malformation. This article discusses about health care giving and follow-up for the epileptic pregnant women, pointing recommendations for preconception care, prenatal management, labor conduct, peculiarities in puerperium and treatment of convulsive crisis when needed. There will be approached pharmacological and non-pharmacological aspects, such as follow up exams and general orientations, having as a goal to contribute to an more abrangent and proper support of this more vulnerable group of patients under the care responsibility of obstetrician-gynecologist ad neurologist doctors.(AU)

RESUMO

Gestational trophoblastic disease is an abnormality of pregnancy that encompasses a group of diseases that differ from each other in their propensity for regression, invasion, metastasis, and recurrence. In the past, it was common for patients with molar pregnancy to present with marked symptoms: copious bleeding; theca lutein cysts; uterus larger than appropriate for gestational age; early preeclampsia; hyperemesis gravidarum; and hyperthyroidism. Currently, with early diagnosis made by ultrasound, most patients are diagnosed while the disease is still in the asymptomatic phase. In cases of progression to trophoblastic neoplasia, staging-typically with Doppler flow studies of the pelvis and chest X-ray, although occasionally with computed tomography or magnetic resonance imaging-is critical to the choice of an appropriate antineoplastic therapy regimen. Because it is an unusual and serious disease that affects women of reproductive age, as well as because its appropriate treatment results in high cure rates, it is crucial that radiologists be familiar with gestational trophoblastic disease, in order to facilitate its early diagnosis and to ensure appropriate follow-up imaging.


Doença trofoblástica gestacional é anomalia da gravidez que engloba um grupo de doenças derivadas do trofoblasto, diferentes entre si na propensão para regressão, invasão, metástase e recidiva. No passado, era comum a paciente portadora de gravidez molar apresentar sintomas exuberantes: hemorragia copiosa, cistos tecaluteínicos, útero aumentado para a idade gestacional, pré-eclâmpsia precoce, hiperêmese e hipertireoidismo. Atualmente, com o diagnóstico precoce feito pela ultrassonografia, a maioria das pacientes é diagnosticada ainda na fase assintomática. Nos casos em que há progressão para neoplasia trofoblástica gestacional, o estadiamento feito com a dopplerfluxometria pélvica e a radiografia de tórax, eventualmente com a tomografia computadorizada e a ressonância magnética, é fundamental na avaliação da escolha do tratamento antineoplásico. Por ser uma doença incomum e grave, que acomete mulheres no menacme, mas cujo tratamento adequado determina elevadas taxas de cura, é fundamental que os radiologistas estejam familiarizados com essa entidade clínica, a fim de auxiliar no diagnóstico precoce e promover seu correto acompanhamento imaginológico.

RESUMO

We report here a case of gestational trophoblastic neoplasia after spontaneous normalization of human chorionic gonadotropin in a patient with a partial hydatidiform mole. This is the second occurrence of this event to be reported and the first one with proven immunohistochemical evidence. Besides showing the treatment for this pregnancy complication, this case report discusses the possibility of reducing the duration of post-molar follow-up, as well as strategies for early recognition of gestational trophoblastic neoplasia after spontaneous remission of molar pregnancy.
