RESUMO
OBJECTIVE: To evaluate the effectiveness of transvaginal ultrasound (TVU) and serum CA-125 measurement in women at different risk of developing ovarian cancer/fallopian tube cancer (OC/FTC) and the incidence of primary peritoneal cancer (PPC) after risk-reducing salpingo-oophorectomy (RRSO). METHODS: Between 2002 and 2014, 661 women at different risk of OC/FTC/PPC due to a family history or BRCA1/2 gene mutation were offered TVU and CA-125 measurement or RRSO as prevention strategies. The detection rate of OC/FTC/PPC was evaluated, and the sensitivity and specificity for CA-125 measurement and TVU were calculated. Survival and event analysis was performed for diagnosed patients. RESULTS: After a median follow-up of 112 months, 12 OC/FTC/PPC cases were detected (2.6/1,000 persons/year). The screening sensitivity was 70%, with 73% for BRCA carriers. Six (50%) of 12 cancers were stage I or II. Among 41 women who underwent RRSO, 2 BRCA1 carriers developed a PPC (4.9%). At 61-month follow-up, overall and event-free survival were 75 and 64%, respectively. CONCLUSIONS: The cancer detection rate in women with BRCA mutation or a strong family history supports the effectiveness of our surveillance program for early diagnosis. Screening for women at lower risk of OC/FTC is not recommended. A residual risk of PPC after RRSO remains for BRCA1 carriers.

Molar degeneration of the trophoblast is a rare, yet possible, complication of pregnancies. Complete hydatidiform mole is the most common histological type among all trophoblastic tumors and it is the result of the fertilization of an empty oocyte from two sperms or by one sperm that then duplicates. Complete mole is characterized by hydropic degeneration of abnormal chorionic villi, diffused trophoblast hyperplasia and the absence of identifiable embryonic or fetal tissue; the hyperplastic trophoblast justifies the common finding of high serum beta HCG levels. Twin molar pregnancy is an uncommon obstetric event, and even less frequent are triplet/quadruplet molar pregnancies. We hereby report a case of a complete hydatidiform mole with two coexistent fetuses in a triplet pregnancy after in vitro fertilization procedure; the pregnancy ended with a therapeutic abortion. During the follow-up, the serum beta human chorionic gonadotropin concentration started to rise, and the diagnosis of post-molar gestational trophoblastic neoplasia was made and consequently methotrexate treatment was started. Due to the rarity of this condition, there are no specific guidelines for the management of multiple pregnancies complicated by complete hydatidiform mole. We therefore performed a review of the literature including all reported cases of triplets/quadruplets pregnancies complicated by complete mole of a fetus focusing on ultrasound diagnosis, treatment and outcomes of this rare and life-threatening condition.

PURPOSE: To establish the accuracy of ultrasound in detecting fetal anomalies looking at the concordance between prenatal and postnatal diagnosis. MATERIALS AND METHODS: Retrospective analysis of concordance between prenatal and postnatal/autoptic diagnosis of fetuses with congenital abnormalities. Data are from a single center (Policlinico di Modena); all fetuses included were born between 2017 and 2018 and with a follow-up of at least 6 months. We included all deliveries (including perinatal deaths) and termination of pregnancy (TOP) for fetal indication. We calculated sensibility, sensitivity, Positive and Negative Likelihood Ratio, positive and negative predictive value of ultrasound. RESULTS: During the study period 5920 deliveries, including perinatal deaths, and 28 TOP for fetal indication were registered at our center. The prevalence of congenital malformations was 2.6% (153/5920). At least one ultrasound was performed in our center in 1250 women delivering in our unit. All 28 TOP had the anomaly scan performed in our center. Among the total 1278 women scanned in our unit, there were 128 (10%) suspicious scans. In 5/128 (3.9%) cases we diagnosed a false alarm; in 8/128 (6.2%) cases an evolutive malformation with in-utero regression. The prenatal diagnosis was confirmed in 77 (60.2%) cases at birth and in 28/128 (21.9%) at postmortem analysis while there were 10/128 false positive (7.8%). Among the 153 congenital malformations diagnosed at birth, the anomaly scan was performed in our Prenatal Medicine Unit in 92 (60.1%) fetuses. Among these, there were 15 false negatives (9.8%) while in 77/92 (83.7%) the malformation at birth agreed with the sonographic diagnosis. Sensitivity and specificity of ultrasound were 87.5% (IC95 80.2-92.8%) and 99.1% (IC95 98.4-99.6%) respectively with a Positive Likelihood Ratio and Negative Likelihood Ratio of 101.3 (IC95 54.5-188.5) and 0.13 (IC95 0.08-0.2); Positive Predictive Value and Negative Predictive Value were 91.3% (IC95 85-95.1%) and 98.7(IC95 98-99.2%). CONCLUSION: Anomaly scan in pregnancy allows the diagnosis of congenital malformations with a sensibility of 87.5% and specificity of 99.1%. The main limitations of this study are its retrospective design and that it was conducted in a single referral center.

OBJECTIVE: To prospectively evaluate the outcome of labor induction in women with oligohydramnios at term. METHODS: This was a prospective case-control study which included 120 consecutive patients with Amniotic Fluid Index (AFI) < or =5 undergoing labor induction. One hundred and sixteen patients with normal amniotic fluid matched for gestational age (+/- 3 days) and Bishop-score served as controls. Inclusion criteria were: requirement of labor induction, singleton pregnancy, nulliparity, Bishop score <5, gestational age > or =266. Preinduction treatment included the use of up to 3 successive doses of dinoprostone intracervical gel (0.5 mg). Vaginal dinoprostone (2 mg) and/or oxytocin were then applied to induction labor, if necessary. RESULTS: The rate of cesarean section in AFI < or = 5 group (38.3%) was not significantly different to that in control group (34.2%). The interval from induction to vaginal delivery was not significantly different for AFI < or =5 group (1499 +/- 895 min.) and control group (1398 +/- 852 min.). The changes in Bishop score evaluated at 6th and 12th hour after dinoprostone were not significantly different in control and AFI< or =5 group. More women in the latter group (11.7% vs 3.3%, Chi Square:4.86, p = 0.027) required the use of drugs in order to manage tachysystole/hyperstimulation allowing a OR = 3.83 (95%C.I. = 1.13-14.27). The length of stay at hospital was 4.2 +/- 1.8 days for AFI < or =5 group and 4.3 +/- 1.3 for control group. CONCLUSIONS: Oligohydranmios at term did not influence the outcome of induction of labour in nulliparous women with unfavorable cervix.

More than one-fifth of ovarian tumors have hereditary susceptibility and, in about 65-85% of these cases, the genetic abnormality is a germline mutation in BRCA genes. Nevertheless, several other suppressor genes and oncogenes have been associated with hereditary ovarian cancers, including the mismatch repair (MMR) genes in Lynch syndrome, the tumor suppressor gene, TP53, in the Li-Fraumeni syndrome, and several other genes involved in the double-strand breaks repair system, such as CHEK2, RAD51, BRIP1, and PALB2. The study of genetic discriminators and deregulated pathways involved in hereditary ovarian syndromes is relevant for the future development of molecular diagnostic strategies and targeted therapeutic approaches. The recent development and implementation of next-generation sequencing technologies have provided the opportunity to simultaneously analyze multiple cancer susceptibility genes, reduce the delay and costs, and optimize the molecular diagnosis of hereditary tumors. Particularly, the identification of mutations in ovarian cancer susceptibility genes in healthy women may result in a more personalized cancer risk management with tailored clinical and radiological surveillance, chemopreventive approaches, and/or prophylactic surgeries. On the other hand, for ovarian cancer patients, the identification of mutations may provide potential targets for biologic agents and guide treatment decision-making.
