Although a rare and challenging condition, cancer during pregnancy should promptly be identified and treated. Not only standards of care guidelines for the underlying disease are taken into account, but also fetal safety might be weighted for clinical decisions. Frequent lack of experience and knowledge about this condition could lead to late diagnosis, imprecise management, suboptimal treatment and fetal and maternal harm. Therefore, this review aims to summarize the current evidence regarding the epidemiology, clinical presentation, diagnostic workup, staging and treatment, including novel treatment modalities for patients diagnosed with cancer during pregnancy.
OBJECTIVES:Hospitalized patients with cancer are at high risk of developing venous thromboembolism, and the risk increases with pregnancy. The aim of this study was to apply a thromboprophylaxis protocol with a venous thromboembolism risk score for hospitalized pregnant women with cancer and to evaluate the effects on maternal morbidity and mortality.METHODS:A longitudinal and prospective study was conducted from December 2014 to July 2016. The venous thromboembolism risk score was modified from the guidelines of the Royal College of Obstetricians and Gynaecologists. Patients were classified as low (score <3) or high risk (score ≥3). The high-risk group received thromboprophylaxis with low-molecular-weight heparin, unless the patient had a contraindication for anticoagulation. One patient could have undergone more than one evaluation.RESULTS:Fifty-two ratings were descriptively analyzed: 34 (65.4%) were classified as high risk, and 28/34 (82.3%) received low-molecular-weight heparin, 1 received unfractionated heparin, and 5 did not receive intervention. Most patients (23/52; 44.2%) had breast cancer. The main risk factors for venous thromboembolism in the high-risk group were chemotherapy (within 6 months; 22/34; 64.7%). No patient exhibited venous thromboembolism, adverse effects of anticoagulation or death up to three months after hospitalization.CONCLUSIONS:Most pregnant women with cancer had a high risk for venous thromboembolism at the time of hospitalization. Breast cancer was the most prevalent cancer, and recent chemotherapy was the main risk factor for anticoagulation. The application of a thromboprophylaxis protocol and determination of a venous thromboembolism risk score for these patients was useful for the prevention of maternal morbidity and mortality due to venous thromboembolism.
Doppler ultrasound is a non-invasive method for evaluating vascularization and is widely used in clinical practice. Gestational trophoblastic neoplasia includes a group of highly vascularized malignancies derived from placental cells. This review summarizes data found in the literature regarding the applications of Doppler ultrasound in managing patients with gestational trophoblastic neoplasia.The PubMed/Medline, Web of Science, Cochrane and LILACS databases were searched for articles published in English until 2014 using the following keywords: “Gestational trophoblastic disease AND Ultrasonography, Doppler.”Twenty-eight articles met the inclusion criteria and were separated into the 4 following groups according to the aim of the study. 1 Doppler ultrasound does not seem to be capable of differentiating partial from complete moles, but it might be useful when evaluating pregnancies in which a complete mole coexists with a normal fetus. 2 There is controversy in the role of uterine artery Doppler velocimetry in the prediction of development of gestational trophoblastic neoplasia. 3 Doppler ultrasound is a useful tool in the diagnosis of gestational trophoblastic neoplasia because abnormal myometrial vascularization and lower uterine artery Doppler indices seem to be correlated with invasive disease. 4 Lower uterine artery Doppler indices in the diagnosis of gestational trophoblastic neoplasia are associated with methotrexate resistance and might play a role in prognosis.CONCLUSION:Several studies support the importance of Doppler ultrasound in the management of patients with gestational trophoblastic neoplasia, particularly the role of Doppler velocimetry in the prediction of trophoblastic neoplasia and the chemoresistance of trophoblastic tumors. Doppler findings should be used as ancillary tools, along with human chorionic gonadotropin assessment, in the diagnosis of gestational trophoblastic neoplasia.
The management of pregnancy of unknown location (PUL) can be a challenging situation, since it can present as several different conditions. Here we describe a rare case of gestational choriocarcinoma arising in the fallopian tube after ovarian induction in an infertile patient. The patient received clomiphene for ovarian induction and had rising levels of human chorionic gonadotropin (hCG) over nine months without sign of pregnancy. After referral to our center, the patient was diagnosed with a paraovarian tumor, which revealed a gestational choriocarcinoma arising in the fallopian tube; the final diagnosis was supported by pathological and cytogenomic analysis. Malignancies, such as gestational trophoblastic disease, should be in the differential diagnosis of PUL; the early recognition of these conditions is key for the proper treatment and favorable outcome.
Este estudo tem como propósito esclarecer o efeito da obesidade nas complicações pós-operatórias e na sobrevida da cirurgia do câncer gástrico. Foram estudados 293 pacientes submetidos a gastrectomia subtotal com linfadenectomia D2 por câncer gástrico no período entre 1990 e 1997.Formaram-se três grupos de acordo com o índice de massa corpórea (IMC Este é um estudo de grande importância para a medicina e para a área de saúde. Primeiro, ele apresenta evidências contundentes sobre a relevância da capacidade física no prognóstico de vida de indivíduos portadores ou não de doença cardiovascular. Segundo, a capacidade física mostrou-se mais importante que alguns fatores de risco que reconhecidamente predispõem à doença cardiovascular. Terceiro, a relação entre a capacidade física e a chance de sobrevivência se mantém mesmo na presença de outros fatores de risco de doença cardiovascular, tais como, hipertensão, doença pulmonar obstrutiva crônica, diabetes, fumo, obesidade e nível total de colesterol.Como todo estudo, ele apresenta alguns aspectos que merecem ressalvas. Por exemplo, foram estudados apenas homens, o que pode limitar os resultados alcançados ao sexo masculino. O estudo inclui apenas americanos; sabe-se que a população americana apresenta algumas peculiaridades que a diferenciam de outras populações. Isto pode restringir os resultados do presente estudo à população americana. A capacidade física foi estimada pela velocidade e inclinação da esteira, método que, apesar de muito utilizado para este fim, não apresentam a mesma especificidade e repro-dutibilidade da ergo-espirometria, que possibilita avaliar diretamente o consumo de oxigênio de pico, considerado o parâmetro mais aceito para medida de capacidade física de pico, tanto em indivíduos saudáveis, como em pacientes com doença cardiovascular.
The incidence of ovarian cancer during pregnancy is low. Most adnexal tumors removed during pregnancy are benign, with ovarian carcinomas found in approximately 1: 10,000–1: 50,000 pregnancies. Literature on this disease is scarce and consists mostly of retrospective studies and case reports. We report the case of a pregnant patient who presented with a primary intestinal-type mucinous adenocarcinoma of the ovary and underwent unilateral salpingo-oophorectomy, with no additional surgical or chemotherapy treatment after the histological diagnosis, despite an infiltrative stromal invasion pattern. To the best of our knowledge, no such case has been previously reported. Conservative treatment in this case of early ovarian carcinoma is possible during pregnancy and should be performed in the Department of Gynecological Oncology and Obstetrics of a tertiary referral hospital. Given the possibility of disease recurrence, such patients require strict clinical oncological surveillance, specialized prenatal care, and assistance from a multidisciplinary team to improve the maternal and perinatal outcomes.
