RESUMO

Genetic testing for cancer predisposition has been curtailed by the cost of sequencing, and testing has been restricted by eligibility criteria. As the cost of sequencing decreases, the question of expanding multi-gene cancer panels to a broader population arises. We evaluated how many additional actionable genetic variants are returned by unrestricted panel testing in the private sector compared to those which would be returned by adhering to current NHS eligibility criteria. We reviewed 152 patients referred for multi-gene cancer panels in the private sector between 2014 and 2016. Genetic counselling and disclosure of all results was standard of care provided by the Consultant. Every panel conducted was compared to current eligibility criteria. A germline pathogenic / likely pathogenic variant (P/LP), in a gene relevant to the personal or family history of cancer, was detected in 15 patients (detection rate of 10%). 46.7% of those found to have the P/LP variants (7 of 15), or 4.6% of the entire set (7 of 152), did not fulfil NHS eligibility criteria. 46.7% of P/LP variants in this study would have been missed by national testing guidelines, all of which were actionable. However, patients who do not fulfil eligibility criteria have a higher Variant of Uncertain Significance (VUS) burden. We demonstrated that the current England NHS threshold for genetic testing is missing pathogenic variants which would alter management in 4.6%, nearly 1 in 20 individuals. However, the clinical service burden that would ensue is a detection of VUS of 34%.

RESUMO

PURPOSE: Germline testing (GT) for prostate cancer (PCA) is now central to treatment and hereditary cancer assessment. With rising demand for and shortage of genetic counseling (GC), tools to deliver pretest informed consent across practice settings are needed to improve access to GT and precision care. Here, we report on Evaluation and Management for Prostate Oncology, Wellness, and Risk (EMPOWER), a patient-choice study for pretest video-based genetic education (VBGE) versus GC to inform urgent practice needs. PATIENTS AND METHODS: Men with PCA or at risk for PCA (family history of PCA) were eligible and could choose pretest VBGE or GC. Outcomes included decisional conflict for GT, change in genetics knowledge, satisfaction, and intention to share results with family and/or providers. Descriptive statistics summarized results with counts and percentages for categorical variables and mean ± standard deviation for continuous variables. Data were compared with Fisher's exact, chi-squared, or Wilcoxon two-sample tests. Mean change in genetics knowledge was compared with t tests. The significance level was set a priori at .05. RESULTS: Data on the first 127 participants were analyzed. Characteristics were White (85.8%), bachelor's degree (66.9%), and PCA diagnosis (90.6%). The majority chose VBGE (71%) versus GC (29%; P < .001). No differences were observed in decisional conflict for GT or satisfaction. Cancer genetics knowledge improved in both groups without significant difference (+0.9 VBGE, +1.8 GC, P = .056). Men who chose VBGE had higher intention to share GT results (96.4% VBGE v 86.4% GC, P = .02). Both groups had high rates of GT uptake (VBGE 94.4%, GC 92%). CONCLUSION: A substantial proportion of men opted for pretest VBGE, with comparable patient-reported outcomes and uptake of GT. The results support the use of pretest video to address the critical GC shortage in the precision era.

RESUMO

BACKGROUND: An important number of breast and ovarian cancer cases is due to a strong genetic predisposition. The main tool for identifying individuals at risk is recognizing a suggestive family history of cancer. We present a prospective study on applying three selected clinical guidelines to a cohort of 1000 Slovenian women to determine the prevalence of at-risk women according to each of the guidelines and analyze the differences amongst the guidelines. METHODS: Personal and family history of cancer was collected for 1000 Slovenian women. Guidelines by three organizations: National Comprehensive Cancer Network (NCCN), American College of Medical Genetics in cooperation with National Society of Genetic Counselors (ACMG/NSGC), and Society of Gynecologic Oncology (SGO) were applied to the cohort. The number of women identified, the characteristics of the high-risk population, and the agreement between the guidelines were explored. RESULTS: NCCN guidelines identify 13.2% of women, ACMG/NSGC guidelines identify 7.1% of women, and SGO guidelines identify 7.0% of women from the Slovenian population, while 6.2% of women are identified by all three guidelines as having high-risk for hereditary breast and ovarian cancer. CONCLUSIONS: We identified 13.7% of women from the Slovenian population as being at an increased risk for breast and ovarian cancer based on their personal and family history of cancer using all of the guidelines. There are important differences between the guidelines. NCCN guidelines are the most inclusive, identifying nearly twice the amount of women as high-risk for hereditary breast and ovarian cancer as compared to the AGMG/NSCG and SGO guidelines in the Slovenian population.

RESUMO

Changing practice guidelines and recommendations have important implications for cancer survivors. This study investigated genetic testing patterns and outcomes and reported family history of pancreatic cancer (FHPC) in a large registry population of breast cancer (BC) patients. Variables including clinical and demographic characteristics, FHPC in a first or second-degree relative, and genetic testing outcomes were analyzed for BC patients diagnosed between 2010 and 2018 in the NYU Langone Health Breast Cancer Database. Among 3334 BC patients, 232 (7%) had a positive FHPC. BC patients with FHPC were 1.68 times more likely to have undergone genetic testing (p < 0.001), but 33% had testing for BRCA1/2 only and 44% had no genetic testing. Pathogenic germline variants (PGV) were identified in 15/129 (11.6%) BC patients with FHPC, and in 145/1315 (11.0%) BC patients without FHPC. Across both groups, updates in genetic testing criteria and recommendations could impact up to 80% of this cohort. Within a contemporary cohort of BC patients, 7% had a positive FHPC. The majority of these patients (56%) had no genetic testing, or incomplete testing by current standards, suggesting under-diagnosis of PC risk. This study supports recommendations for survivorship care that incorporate ongoing genetic risk assessment and counseling.

RESUMO

BACKGROUND: Integration of genetic testing into routine oncology care could improve access to testing. This systematic review investigated interventions and the tailored implementation strategies aimed at increasing access to genetic counselling and testing and identifying hereditary cancer in oncology. METHODS: The search strategy results were reported using the PRISMA statement and four electronic databases were searched. Eligible studies included routine genetic testing for breast and ovarian cancer or uptake after universal tumour screening for colorectal or endometrial cancer. The titles and abstracts were reviewed and the full text articles screened for eligibility. Data extraction was preformed using a designed template and study appraisal was assessed using an adapted Newcastle Ottawa Scale. Extracted data were mapped to Proctor's et al outcomes and the Consolidated Framework for Implementation Research and qualitatively synthesised. RESULTS: Twenty-seven studies, published up to May 2020, met the inclusion criteria. Twenty-five studies ranged from poor (72%), fair to good (28%) quality. Most interventions identified were complex (multiple components) such as; patient or health professional education, interdisciplinary practice and a documentation or system change. Forty-eight percent of studies with complex interventions demonstrated on average a 35% increase in access to genetic counselling and a 15% increase in testing completion. Mapping of study outcomes showed that 70% and 32% of the studies aligned with either the service and client or the implementation level outcome and 96% to the process or inner setting domains of the Consolidated Framework for Implementation Research. CONCLUSION: Existing evidence suggests that complex interventions have a potentially positive effect towards genetic counselling and testing completion rates in oncology services. Studies of sound methodological quality that explore a greater breadth of pre and post implementation outcomes and informed by theory are needed. Such research could inform future service delivery models for the integration of genetics into oncology services.

RESUMO

The demand for genetic testing of hereditary breast cancer genes such as BRCA1 and BRCA2 has continued to increase with the lowering costs of testing, raised awareness in the general public, and implications for breast cancer treatment when a patient is identified as having a germline pathogenic variant. Historically within Australia, patients affected by high genetic risk breast cancers have been referred to a familial cancer centre (FCC) for assessment and testing, resulting in wait times for an appointment for pre- and post-test genetic counselling and an increased demand on the public-funded FCC. To improve patient access and pace of genetic testing, as well as refocus FCC resources, a mainstream clinical genetic testing program was rolled out in September 2017 through the Parkville FCC (PFCC) in Australia at 10 hospital sites. This program enables specialist doctors of eligible patients affected by breast cancer to arrange genetic testing directly at an oncology/surgical appointment and follow up the results as part of the patients' routine clinical care. In this model, the specialist doctor is responsible for any treatment implications of the genetic test result, and the PFCC is responsible for result interpretation, future cancer risk, family cascade testing and segregation testing where warranted. To date the program has had successful uptake, a notable pathogenic variant detection rate, reduced the burden on the PFCC enabling a reallocation of resources and has streamlined the process of genetic testing for eligible patients. Investigation into the patient and clinician experiences of the mainstream program is required.

RESUMO

Introducción: El asesoramiento genético constituye el proceso central en el manejo de trastornos de causa genética, de ahí la importancia de evaluar su efectividad. Objetivo: Evaluar la efectividad y aspectos éticos del asesoramiento genético en Cuba. Métodos: Se realizó un estudio observacional - descriptivo - retrospectivo de 2003 a 2013, que consistió en la realización de entrevistas, basadas en instrumentos diseñados y validados, a familias atendidas en los servicios de asesoramiento genético y a otros ciudadanos, la muestra quedó constituida por 13 142 individuos. Resultados: El nivel de conocimientos adquiridos fue bueno en 71,1 por ciento de los participantes; predominaron las decisiones muy racionales (68,4 por ciento); en 74,9 por ciento de las familias se logró un buen ajuste en relación con la situación particular. Existe en la población una elevada satisfacción con los servicios de asesoramiento genético (89,8 por ciento). La mayoría considera la prevención secundaria de enfermedades el objetivo más prioritario de la genética médica (81,3 por ciento), 93 por ciento está de acuerdo con el aborto selectivo como opción reproductiva ante el diagnóstico de enfermedades genéticas graves y de inicio precoz, y 76,5 por ciento prefiere el enfoque no directivo del asesoramiento genético. Conclusiones: El asesoramiento genético que se ofrece en los servicios de genética médica de Cuba es efectivo, satisface las expectativas de la población y cumple con principios éticos universalmente aceptados. La metodología diseñada y aplicada, basada en la organización de los servicios de genética en Cuba, permite la evaluación sistemática del asesoramiento genético, lo que propicia su mejoramiento y la posibilidad de trazar estrategias locales para aumentar su eficacia y alcanzar su excelencia(AU)


Introduction: Genetic counseling is the central process in the management of genetic disorders, hence the importance of assessing its effectiveness. Objective: Assess the effectiveness and ethical aspects of genetic counseling in Cuba. Methods: An observational - descriptive - retrospective study was conducted from 2003 to 2013, which consisted of conducting interviews based on instruments designed and validated with families assisted in genetic counseling services and other citizens; the sample consisted of 13 142 individuals. Results: The level of knowledge acquired was good in 71.1 percent of the participants; very rational decisions predominated (68.4 percent); in 74.9 percent of the families a good adjustment was achieved in relation to the particular situation. The population is highly satisfied with the genetic counselling services (89.8 percent). Most consider secondary diseases prevention to be the top priority for medical genetics (81.3 percent), 93 percent agree with selective abortion as a reproductive option after a diagnosis of serious and early-onset genetic diseases, and 76.5 percent prefer the non-directive approach to genetic counseling. Conclusions: The genetic counseling offered in the medical genetics services of Cuba is effective, satisfies the expectations of the population and complies with universally accepted ethical principles. The methodology designed and applied, based on the organization of genetic services in Cuba, allows the systematic assessment of genetic counseling, which males possible their improvement and the chance of devising local strategies to increase their effectiveness and achieve excellence in the service(AU)

RESUMO

OBJECTIVES: Genetic testing (GT) companies have developed patient education videos to supplement or replace pre-test genetic counseling (GC) by certified genetic counselors (CGC). The aim of this study was to assess the quality of these videos compared to the standard of care (SOC). METHODS: Videos from four major GT companies were selected from an internet search identifying pre-test patient education videos. A scoring rubric with 22 questions and 36 total points was devised to assess quality metrics, as described by the National Cancer Institute and National Society of Genetic Counselors. Twenty-two individuals with varying genetics expertise (3 gynecologic oncologists, 3 academic generalists, 4 CGC, a genetics community health worker, 3 cancer care navigators, and 8 medical students) scored each video. Scorers were blinded to others' assessments. RESULTS: Invitae had the highest median score (26/36), followed by Myriad (22/36), Ambry (17.5/36), and Color (15/36). All videos scored highly in explaining DNA basics, cancer development, and hereditary cancer predisposition. All addressed benefits of GT but failed to address potential disadvantages. All scored poorly in explaining medical terms and different GT options. There was variability in addressing patient concerns including cost, privacy, and procedure. CONCLUSIONS: There is significant variation in the content of pre-test patient education videos between GT companies. None of the videos met the SOC for pre-test GC, and none addressed disadvantages of GT, possibly due to a conflict of interest. With improvement in content, accessibility, and use of interactive platforms, these videos may serve as an adjunct to in-person pre-test GC.

RESUMO

Predictive BRCA testing is offered to asymptomatic individuals to predict future risk where a variant has been identified in a relative. It is uncertain whether all eligible relatives access testing, and whether this is related to health care inequalities. Our aim was to analyse trends and inequalities in uptake of testing, and identify predictors of testing and time-to-receipt of testing. A database from April 2010 to March 2017 was collated. Multivariate analysis explored individual associations with testing. Predictor variables included gender, BRCA test type, cancer history, Index of Multiple Deprivation (IMD) and education status. To evaluate factors associated with time-to-testing, a Cox proportional-hazards (CP) model was used. Of 779 tests undertaken, 336 (43.1%) were identified with a BRCA variant. A total of 537 (68.9%) were female and in 83.4% (387/464) of probands, predictive testing was received by relatives. Analysis identified inequalities since decreased testing was found when the proband was unaffected by cancer (OR 0.14, 95% CI 0.06-0.33). Median time-to-testing was 390 days (range, 0-7090 days) and the CP model also identified inequalities in the hazard ratio (HR) for testing for people aged >40 was higher than for aged <40 (HR 1.41, 95% CI 1.20-1.67) and BRCA2 testing was higher than for BRCA1 testing (HR 1.39, 95% CI 1.18-1.64). Reduced testing was found when probands were unaffected by cancer and time-to-testing was found to vary by age and BRCA1/2 test. Given limited study sample size, further research is recommended to examine inequalities in predictive BRCA testing.

RESUMO

As demand for germline genetic testing for cancer patients increases, novel methods of genetic counseling are required. One such method is the mainstream consent pathway, whereby a member of the oncology team (rather than a genetic specialist) is responsible for counseling, consenting, and arranging genetic testing for cancer patients. We systematically reviewed the literature for evidence evaluating mainstream pathways for patients with breast, ovarian, colorectal, and prostate cancer. Medline, EMBASE, and Cochrane Library were searched for studies that met inclusion and exclusion criteria. Article references were checked for additional studies. Trial databases were searched for ongoing studies. Of the 13 papers that met inclusion criteria, 11 individual study groups were identified (two study groups had two publications each). Ten of the 11 studies evaluated the acceptability, feasibility, and impact of BRCA testing for patients and/or clinicians in different clinical settings in breast and ovarian cancer, while the final study explored the attitudes of colorectal specialists toward genetic testing for colorectal cancer. None involved prostate cancer. Overall, mainstream pathways were acceptable and feasible. Medical oncologist- and nurse-driven pathways were particularly successful, with both patients and clinicians satisfied with this process. Although the content of pretest counseling was less consistent compared with counseling via the traditional model, patients were largely satisfied with the education they received. Further research is required to evaluate the mainstream pathway for men with prostate cancer.

RESUMO

Background: Ongoing clinical trials are investigating PARP inhibitors to target the DNA damage repair (DDR) pathway in prostate cancer. DDR mutation screening will guide treatment strategy and assess eligibility for clinical trials. Materials & methods: This systematic review estimated the rate of DDR mutation testing or genetic counseling among men with or at risk of prostate cancer. Results: From 6856 records, one study fulfilled the inclusion criteria and described men undiagnosed with prostate cancer with a family history of BRCA1/2 mutation who received DDR mutation testing. Conclusion: With only one study included in this first systematic review of DDR mutation testing or genetic counseling in men with or at risk of prostate cancer, more research is warranted.

RESUMO

Genotype-first approach allows to systematically identify carriers of pathogenic variants in BRCA1/2 genes conferring a high risk of familial breast and ovarian cancer. Participants of the Estonian biobank have expressed support for the disclosure of clinically significant findings. With an Estonian biobank cohort, we applied a genotype-first approach, contacted carriers, and offered return of results with genetic counseling. We evaluated participants' responses to and the clinical utility of the reporting of actionable genetic findings. Twenty-two of 40 contacted carriers of 17 pathogenic BRCA1/2 variants responded and chose to receive results. Eight of these 22 participants qualified for high-risk assessment based on National Comprehensive Cancer Network criteria. Twenty of 21 counseled participants appreciated being contacted. Relatives of 10 participants underwent cascade screening. Five of 16 eligible female BRCA1/2 variant carriers chose to undergo risk-reducing surgery, and 10 adhered to surveillance recommendations over the 30-month follow-up period. We recommend the return of results to population-based biobank participants; this approach could be viewed as a model for population-wide genetic testing. The genotype-first approach permits the identification of individuals at high risk who would not be identified by application of an approach based on personal and family histories only.

RESUMO

OBJECTIVE: Studies have shown that prenatal exome sequencing (PES) improves diagnostic yield in cases of fetal structural malformation. We have retrospectively analysed PES cases from two of the largest fetal medicine centres in the UK to determine the impact of results on management of a pregnancy. DESIGN: A retrospective review of clinical case notes. SETTING: Two tertiary fetal medicine centres. POPULATION: Pregnancies with fetal structural abnormalities referred to clinical genetics via a multidisciplinary team. METHODS: We retrospectively reviewed the notes of all patients who had undergone PES. DNA samples were obtained via chorionic villus sampling or amniocentesis. Variants were filtered using patient-specific panels and interpreted using American College of Medical Genetics guidelines. RESULTS: A molecular diagnosis was made in 42% (18/43) ongoing pregnancies; of this group, there was a significant management implication in 44% (8/18). A positive result contributed to the decision to terminate a pregnancy in 16% (7/43) of cases. A negative result had a significant impact on management in two cases by affirming the decision to continue pregnancy. CONCLUSIONS: We demonstrate that the results of PES can inform pregnancy management. Challenges include variant interpretation with limited phenotype information. These results emphasise the importance of the MDT and collecting phenotype and variant data. As this testing is soon to be widely available, we should look to move beyond diagnostic yield as a measure of the value of PES. TWEETABLE ABSTRACT: Prenatal exome sequencing can aid decision-making in pregnancy management; review ahead of routine implementation in NHS.

RESUMO

Since the advent of preimplantation genetic testing for aneuploidy (PGT-A) in the 1990s, substantial changes in test methodology and technology now allow the detection and reporting of intermediate chromosome copy number (commonly referred to as mosaicism) for aneuploidy in a trophectoderm biopsy sample. Clinicians are grappling with how to interpret such findings and how to counsel patients about embryo transfer decision-making. This document reviews the available literature and outlines the various issues surrounding the reporting of intermediate copy number and consideration of storage or transfer of blastocysts with intermediate copy number results. This document does not endorse, nor does it suggest that PGT-A is appropriate for all cases of in vitro fertilization.

RESUMO

Objective. Clinicians regularly use panel genetic testing to identify hereditary breast cancer risk, but this practice increases the rate of receiving an ambiguous test result, the variant of uncertain significance (VUS). VUS results are a growing and long-term challenge for providers and have caused negative patient outcomes. The objective of this study was to elicit expert opinions about patients' decision making after receiving a VUS result to provide future guidance for VUS disclosure. Methods. Using an adapted mental models approach, experts (N = 25) completed an online survey and in-depth interview eliciting qualitative judgments of the factors relevant to informed patient decision making after receiving a VUS result. Content analysis of interview transcripts clarified the basis for these judgments. Results. Participants identified 11 decisions facing patients after receiving VUS results grouped into ambiguity management or risk management. The experts also identified 24 factors relevant to each decision, which reflected 2 themes: objective factors (e.g., clinical information, guidelines) and psychosocial factors (e.g., understanding or risk perception). Conclusion. This study presents an adaptation of the mental models approach for communication under conditions of ambiguity. Findings suggest providers who present VUS results from genetic testing for hereditary breast cancer should discuss decisions related to ambiguity management that focus on hope for future reclassification, and be directive when discussing risk management decisions. Objective and psychosocial factors should influence both ambiguity and risk management decisions, but especially risk management decisions.

RESUMO

BACKGROUND: The accurate interpretation of BRCA1/2 variants becomes increasingly important in breast cancer and other related cancers including ovarian cancer, prostate cancer, pancreatic cancer and so forth. In the past decades, especially before year 2015, limitations of techniques and lack of databases and guidelines have led to possible misinterpretation of the clinical significance of sequence variants of BRCA1/2. A published study reported reclassification of some BRCA1/2 variants previously classified as variants of uncertain significance (VUS) to likely pathogenic in breast or ovarian cancer patients from Korea. However, little is known about the situation in Chinese population. METHODS: We retrospectively retrieved 109 publications studying about BRCA1/2 variants of Chinese population from the year 1999 to year 2019 (March). After excluding publications of meta-analysis and publications with missing data, 72 publications were eventually retained for subsequent analysis. In total, 1,351 BRCA variants (673 BRCA1 variants and 678 BRCA2 variants) derived from 42,430 Chinese cancer patients were standardized and reinterpreted using ACMG/AMP 2015 guidelines and China Expert Consensus on BRCA variant interpretation by genetic counselors. RESULTS: Among the 1,351 BRCA variants, the majority of interpretation (91.7%, 1,239/1,351) remained the same as previously published. However, there were 112 (8.3%, 112/1,351) variants (64 BRCA1, 48 BRCA2) reclassified with different categories. CONCLUSIONS: Our results demonstrated that clinical significance of not only VUS, but also pathogenic/likely pathogenic variants varied from time to time in the Chinese population. Precise reinterpretation of BRCA1/2 variants is of crucial importance to genetic counseling or clinical decision-making for risk individuals or patients.

RESUMO

PURPOSE: To develop recommendations concerning the management of male breast cancer. METHODS: ASCO convened an Expert Panel to develop recommendations based on a systematic review and a formal consensus process. RESULTS: Twenty-six descriptive reports or observational studies met eligibility criteria and formed the evidentiary basis for the recommendations. RECOMMENDATIONS: Many of the management approaches used for men with breast cancer are like those used for women. Men with hormone receptor-positive breast cancer who are candidates for adjuvant endocrine therapy should be offered tamoxifen for an initial duration of five years; those with a contraindication to tamoxifen may be offered a gonadotropin-releasing hormone agonist/antagonist plus aromatase inhibitor. Men who have completed five years of tamoxifen, have tolerated therapy, and still have a high risk of recurrence may be offered an additional five years of therapy. Men with early-stage disease should not be treated with bone-modifying agents to prevent recurrence, but could still receive these agents to prevent or treat osteoporosis. Men with advanced or metastatic disease should be offered endocrine therapy as first-line therapy, except in cases of visceral crisis or rapidly progressive disease. Targeted systemic therapy may be used to treat advanced or metastatic cancer using the same indications and combinations offered to women. Ipsilateral annual mammogram should be offered to men with a history of breast cancer treated with lumpectomy regardless of genetic predisposition; contralateral annual mammogram may be offered to men with a history of breast cancer and a genetic predisposing mutation. Breast magnetic resonance imaging is not recommended routinely. Genetic counseling and germline genetic testing of cancer predisposition genes should be offered to all men with breast cancer.

RESUMO

Data about patient reported outcomes from cancer genetics services (CGS) are lacking but are essential to guide service evaluation and improvements. We measured improvement in empowerment, following genetic counseling in Singapore using a culturally-adapted version of the Genetic Counseling Outcome Scale (GCOS-24); and sought to identify factors associated with change in empowerment. The GCOS-24 was administered to 155 patients of the CGS, at pre- and post-counseling or testing timepoints. Of which, 110 patients underwent genetic testing. Individual pre- and post-counseling responses were subjected to Rasch analysis; the scale was subsequently split into cognitive control (CC) and emotional control (EC) domains. Associations of baseline characteristics with changes in pre- and post-CC and EC scores were assessed using multiple regression analysis. Both CC and EC scores showed significant improvement following genetic counseling and testing. While all items in the CC domain of being showed increases at follow-up, aspects of EC related to alleviating negative emotions (P = .88) and hopelessness (P = .2) did not show significant improvement. Our study revealed significant improvement in empowerment in patients who have received cancer genetic counseling, while revealing a need to cultivate hope and facilitate the alleviation of negative emotions in patients during genetic counseling.

RESUMO

RESUMEN Introducción: Uno de los temas que presenta más interés en los obstetras es el relacionado con la gestación gemelar. Su diagnóstico nos permite clasificarla como una gestación de riesgo, en la cual el estudio ecosonográfico es muy importante al proporcionar datos relacionados con el tipo de placentación. Presentación de caso: Se realiza ecografía prenatal del I trimestre para confirmación de diagnóstico presuntivo de onfalocele, donde se constata embarazo gemelar, monoamniótico, monocorial. Se realiza el diagnóstico de síndrome de perfusión arterial reversa feto a feto. El estado anormal del "corazón" del feto podría identificarse como una holoacardia; pero el grado de malformación que presenta no se ajusta a ninguno de los criterios de esta clasificación. Teniendo en cuenta el hallazgo precoz y la elevada mortalidad que se asocia en estos casos se sugirió la opción de interrumpir el embarazo. Conclusiones: El asesoramiento genético referido a las posibles terapias a emplear estaría limitado en este caso, debido a la alta morbimortalidad perinatal, la falta de experiencia en relación con el tratamiento medicamentoso, y la escasa disponibilidad de técnicas para la intervención fetal(AU)


ABSTRACT Introduction: One of the topics of most interest to obstetricians is related to twin pregnancy. Its diagnosis allows to classify it as a risk gestation, in which the echo-sonographic study is very important because it provides data related to the type of placentation. Case report: First trimester prenatal ultrasound is performed to confirm the presumptive diagnosis of omphalocele, revealing twin, monoamniotic, monochorial pregnancy. The diagnosis of fetus-to-fetus reverse arterial perfusion syndrome is made. The abnormal state of the fetus´s heart could be identified as a holoacardia; but the degree of malformation it presents does not fit any of the criteria of this classification. Taking into account the early finding and the high mortality associated in these cases, the option of interrupting the pregnancy. Conclusions: Genetic counseling regarding possible therapies to be used would be limited in this case, due to the high perinatal morbidity and mortality, the lack of experience in relation to drug treatment, and the limited availability of techniques for fetal intervention(AU)
