ABSTRACT
OBJECTIVE: To assess whether the incidence and aggressiveness of molar pregnancy (MP) and postmolar gestational trophoblastic neoplasia (GTN) changed during the COVID-19 pandemic. DESIGN: Observational study with two separate designs: retrospective multicentre cohort of patients with MP/postmolar GTN and a cross-sectional analysis, with application of a questionnaire. SETTING: Six Brazilian Reference Centres on gestational trophoblastic disease. POPULATION: 2662 patients with MP/postmolar GTN treated from March-December/2015-2020 were retrospectively evaluated and 528 of these patients answered a questionnaire. METHODS: Longitudinal retrospective multicentre study of patients diagnosed with MP/ postmolar GTN at presentation and a cross-sectional analysis, with application of a questionnaire, exclusive to patients treated during the period of study, to assess living and health conditions during the COVID-19 pandemic compared with previous years. MAIN OUTCOME MEASURES: The incidence of MP/postmolar GTN. RESULTS: Compared with the last 5 pre-pandemic years, MP/postmolar GTN incidence remained stable during 2020 (COVID-19 pandemic). Multivariable logistic regression, adjusted for the patient age, showed that during 2020, presentation with MP was more likely to be >10 weeks of gestation (adjusted odds ratio [aOR] 2.50, 95% confidence interval [CI] 1.90-3.29, P < 0.001), have a pre-evacuation hCG level ≥100 000 iu/l (aOR 1.77, 95% CI 1.38-2.28, P < 0.001) and time to the initiation of chemotherapy ≥7 months (aOR 1.86, 95% CI 1.01-3.43, P = 0.047) when compared with 2015-2019. CONCLUSIONS: Although the incidence of MP/postmolar GTN remained stable during the COVID-19 pandemic in Brazil, the pandemic was associated with greater gestational age at MP diagnosis and more protracted delays in initiation of chemotherapy for postmolar GTN.

STUDY OBJECTIVE: To present the first hysteroscopic findings of 2 cases of complete hydatidiform mole (CHM) and partial hydatidiform mole (PHM) within the context of the patients' clinical histories. DESIGN: Presentation of 2 hysteroscopic videos with narration of the intrauterine findings of molar pregnancy (MP) from Rio de Janeiro Gestational Trophoblastic Disease Reference Center. SETTING: MP is characterized by abnormal fertilization that generates 2 clinical syndromes: CHM and PHM [1]. INTERVENTIONS: In the first case, the patient was aged 50 years, and hysteroscopy was indicated to assess abnormal uterine bleeding in the presence of normal serum human chorionic gonadotropin (hCG) and transvaginal ultrassonography showing an endometrial cavity with heterogeneous content. Hysteroscopy found translucent hydropic structures diagnosed as CHM. The negative hCG value was due to the hook effect (hCG after dilution: 2 240 000 IU/L). In the second case, an 18-year-old patient underwent hysteroscopy to assess the endometrial cavity with retained abortion at 7 weeks in which, during conservative management, the hCG level increased over 4 weeks from 25 000 IU/L to 58 000 IU/L. Hysteroscopy visualized the embryo with its umbilical cord and hydatidiform vesicles diagnosed as PHM. CONCLUSION: MP can be an incidental finding during hysteroscopy for abnormal uterine bleeding or retained abortion [2-4]. Knowing its morphology during hysteroscopy is helpful for the correct management of this uncommon clinical situation. Hysteroscopy as an adjunct diagnostic tool (not as first-line treatment for MP) can be of significant benefit in challenging clinical scenarios. Further studies should assess the possible risk of spreading molar cells into the peritoneal cavity owing to hysteroscopic fluid.

This report presents the case of a patient with gestational trophoblastic neoplasia after a partial hydatidiform mole formed in the Fallopian tube. Ectopic molar pregnancy is a rare condition, with an estimated incidence of 1 in every 20,000 to 100,000 pregnancies; less than 300 cases of it have been reported in the Western literature. The present report is important because it presents current diagnostic criteria for this rare condition, which has been incorrectly diagnosed in the past, not only morphologically but also immunohistochemically. It also draws the attention of obstetricians to the occurrence of ectopic molar pregnancy, which tends to progress to Fallopian tube rupture more often than in cases of ectopic non-molar pregnancy. Progression to gestational trophoblastic neoplasia ensures that patients with ectopic molar pregnancy must undergo postmolar monitoring, which must be just as thorough as that of patients with intrauterine hydatidiform moles, even if chemotherapy results in high cure rates.
Esse relato apresenta um caso de neoplasia trofoblástica gestacional após mola hidatiforme parcial ocorrida na tuba uterina. Trata-se de uma associação rara, cuja incidência estima-se de 1 em cada 20.000 a 100.000 gestações, havendo menos de 300 casos apresentados na literatura ocidental. O tema é importante porque apresenta critérios diagnósticos atuais para essa ocorrência incomum, que vinha sendo diagnosticada equivocadamente, não apenas sob o ponto de vista morfológico, como também imunohistoquímico. Da mesma forma, alerta o obstetra para a ocorrência da gravidez molar ectópica, que tende a evoluir com rotura tubária mais frequentemente do que os casos de gravidez ectópica não molar. Por fim, a evolução do caso para neoplasia trofoblástica gestacional impõe às pacientes com gravidez ectópica molar a necessidade de seguimento pós-molar tão rigoroso quanto nos casos de mola hidatiforme intrauterina, ainda que o tratamento quimioterápico determine elevadas taxas de cura.

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.

The Gestational Trophoblastic Disease includes an interrelated group of diseases originating from placental tissue, with distinct behaviors concerning local invasion and metastasis. The high sensitivity of the serial dosages of human chorionic gonadotrophin, combined with advances in chemotherapy treatment, have made gestational trophoblastic neoplasia curable, most often through chemotherapy. However, surgery remains of major importance in the management of patients with gestational trophoblastic disease, improving their prognosis. Surgery is necessary in the control of the disease's complications, such as hemorrhage, and in cases of resistant/relapsed neoplasia. This review discusses the indications and the role of surgical interventions in the management of women with molar pregnancy and gestational trophoblastic neoplasia. RESUMO Doença trofoblástica gestacional inclui um grupo interrelacionado de doenças originadas do tecido placentário, com tendências distintas de invasão local e metástase. A alta sensibilidade das dosagens seriadas de gonadotrofina coriônica humana aliada aos avanços do tratamento quimioterápico tornou a neoplasia trofoblástica gestacional, curável, na maioria das vezes, através da quimioterapia. No entanto, a cirurgia permanece ainda, da maior importância na condução de pacientes com doença trofoblástica gestacional, melhorando seu prognóstico. A cirurgia é necessária no controle de complicações da doença, tais como hemorragia, e em casos de neoplasia resistente/recidivada. Esta revisão discute as indicações e o papel das intervenções cirúrgicas durante o manejo de mulheres com gravidez molar e neoplasia trofoblástica gestacional.
