Primary Liver Carcinoma Complicating Pregnancy

EDITORIAL COMMENT": We accepted this case report because the Australian population now has many women who are hepatitis B surface antigen positive. This case will remind readers that primary carcinoma of the liver can occur in such women and that effective management is now available by spectacular major surgery. Ideally all women (and men) who are hepatitis B surface antigen positive should have regular (every 1–2 years) serum alpha fetoprotein estimations to facilitate early diagnosis of primary hepatocellular carcinoma.
Summary: Primary hepatic carcinoma complicating pregnancy has been sporadically reported in the literature. Its association with grossly raised serum alphafetoprotein values is of particular interest to obstetricians who perform routine maternal alphafetoprotein screening in the second trimester. A case with favourable maternal and fetal outcome is presented.

Elevated Serum Alpha Fetoprotein and Normal Liquor Alpha Fetoprotein Values in Association with an Abdominal Pregnancy

Summary: A case report is described in which abdominal pregnancy was misdiagnosed by ultrasound scanning as a pregnancy within a horn of a bicornuate uterus. Two serum alpha fetoprotein (SAFP) results were greatly elevated and an amniocentesis was performed, the liquor alpha fetoprotein (LAFP) and karyotype were normal. Elective Caesarean section was performed at 38 weeks for a persistent transverse lie and an abdominal pregnancy was found. The outcome was excellent for both the mother and child.
This is the first reported case of amniocentesis and measurement of LAFP in an abdominal pregnancy and confirms abdominal pregnancy as a rare cause of an elevated SAFP.     

Alpha fetoprotein (AFP) in the management of pregnancy

Alpha fetoprotein (AFP) is the most important specifically fetal serum protein. This protein disappears after the birth. Therefore it is important to detect it in adults as it is almost inevitably a sign of appearance of a primitive liver carcinoma. The dosage of alpha fetoprotein in the amniotic fluid is important as its increase reveals an abnormality of the fetal neural tube. It is possible to establish a dosage of AFP in the amniotic fluid with quantitative immunochemical methods or with quantitative immuno-electrophoeresis. Recent radio-immunochemical methods allow to test the serum variations of AFP in normal adults, particularly during pregnancy. Quantitative studies of AFP in the maternal serum and the dosage of the amniotic fluid allow to detect signs of fetal malformations. Correlations between AFP in the amniotic fluid and AFP in the maternal serum give information on the age of the pregnancy, fetal maturity and normal or pathological development of the pregnancy.     

Prediction of fetal outcome in threatened abortion by maternal serum placental lactogen and alpha fetoprotein.

Abnormally low human placental lactogen (HPL) or high alpha fetoprotein (AFP) levels in maternal serum are unfavorable prognostic signs in women with threatened abortion but normal levels cannot be used to discriminate between viable and nonviable pregnancies. Out of 112 women with threatened abortion, 69 aborted; of these, 36 had a low HPL level and they all aborted. Five women had an increased AFP concentration. Four of these aborted and the remaining case was a twin pregnancy in which one fetus died and the other survived. HPL and AFP levels provide complementary information as to the fetal outcome in threatened abortion. This was indicated by a normal HPL level in all of the five cases with raised maternal AFP, and by a normal AFP level in 35 of the 36 women with low maternal HPL.     

Maternal serum alpha-fetoprotein screening: a report of the Forsyth County project

A pilot screening program for the prenatal detection of neural tube defects has been conducted in Forsyth County, North Carolina. During the first 2 years of the program, 3,476 women were screened by quantitating levels of maternal serum alpha fetoprotein. Three neural tube defects and one case of multiple congenital anomalies with severe gastroschisis were detected as a result of the screening program. Outcome of pregnancy has been monitored in this group of women and no false negatives have been reported. No false positive amniotic fluid alpha-fetoprotein values were observed and no normal fetuses were aborted. Data gathered from this screening program again document the validity of maternal serum screening. The method of implementing a program for the prenatal decision of neural tube defects in urban areas is discussed.     

Disseminated peritoneal tuberculosis mimicking advanced-stage endodermal sinus tumor: a case report

Abstract.   Dursun P, Ersoz S, Gultekin M, Aksan G, Yüce K, Ayhan A. Disseminated peritoneal tuberculosis mimicking advanced-stage endodermal sinus tumor: a case report. Int J Gynecol Cancer 2006; 16(Suppl. 1): 303–307.
It is well known that peritoneal tuberculosis may mimic advanced-stage epithelial ovarian carcinoma because of similar clinical, radiologic, and laboratory findings. However, disseminated peritoneal tuberculosis mimicking advanced-stage endodermal sinus tumor (ESS) has not been reported previously. An 18-year-old nulliparous woman came with the complaint of pelvic pain and weight loss. Imaging studies demonstrated that she had multiple peritoneal implants and left adnexial mass. Also, laboratory studies showed elevated CA125 and alpha fetoprotein levels suggesting an initial diagnosis of ESS. However, intraoperative frozen section examination showed caseous necrosis, and she was diagnosed as having disseminated peritoneal tuberculosis. Two months after the initial exploration, the patient required liver transplantation because of hepatic failure due to widespread hepatic involvement of the tuberculosis. Concomitant peritoneal and hepatic involvement of tuberculosis may cause false elevation of multiple tumor markers of gynecological cancers and may lead to misdiagnosis and mismanagement of patients. Elevation of these markers should be carefully investigated especially in premenopausal women. To our knowledge, this is the first reported case of peritoneal tuberculosis misdiagnosed as endodermal sinus tumor.     

Prospective prenatal serum screening for Down syndrome in Venezuela

OBJECTIVE: To assess the usefulness of triple-marker screening for Down syndrome in Venezuela. METHOD: Maternal serum concentrations of alpha fetoprotein (AFP), beta human chorionic gonadotropin (beta-hCG), and unconjugated estriol (uE3) were measured weekly in 3895 women from the 15th to the 20th week of pregnancy. Population-specific likelihood ratios were determined and used to calculate the risk of fetal Down syndrome for each pregnancy. RESULTS: The median multiple of the median values for AFP, beta-hCG, and uE3 concentrations were 0.69, 2.10, and 0.67 for the affected pregnancies. The likelihood ratio for a positive result was 1:19. The detection and false-positive rates were 69.23% and 5.8%. CONCLUSION: These findings were consistent with reported data and therefore confirmed triple-marker serum screening as effective and suitable for prenatal care in Venezuela. Latin American governments and Health Agencies should recommend offering this screening method to all pregnant women.     

Hepatoid carcinoma of the ovary: immunohistochemical finding of one case and literature review

Hepatoid carcinoma is a rare ovarian tumor and is thought to be a histopathologic subtype different from hepatoid type yolk sac tumor based on its pathologic features. A 63-year-old woman who had postmenopausal bleeding and lower abdominal pain was found to have right ovarian mass on pelvic examination and computed tomography. She had high serum levels of alpha fetoprotein (AFP) and CA125. Histologically, the tumor resembled hepatocellular carcinoma by architectural and cytologic features. Immunohistochemically tumor cells were immunoreactive for AFP, alpha 1 antitrypsin, and carcinoembryonic antigens.     

Unexplained elevated midtrimester maternal serum levels of alpha fetoprotein, human chorionic gonadotropin, or low unconjugated estriol: recurrence risk and association with adverse perinatal outcome

OBJECTIVE: To determine if women experiencing an unexplained elevated maternal serum alpha fetoprotein (MSAFP; > or =2.0 MoM) or human chorionic gonadotropin (hCG; > or =2.0 MoM), or low unconjugated estriol (E3; < or =0.5 MoM) in one pregnancy are at increased risk for similar results in a subsequent pregnancy, and to determine if recurrence of these analyte extremes is associated with adverse perinatal outcome. METHODS: We identified all women delivering two consecutive singleton pregnancies at one hospital between 1992-1997 for whom second trimester trisomy 21 serum screen was performed in each pregnancy. All screens were performed in a single laboratory. Each pregnancy delivered after 20 weeks and had gestational age confirmed by ultrasound prior to 24 weeks. Subjects were excluded if a fetal anomaly or aneuploidy was present. Adverse outcomes included abruption, oligohydramnios, preeclampsia, preterm membrane rupture, preterm delivery, stillbirth, birthweight <10th centile, and admission to neonatal intensive care unit (NICU). RESULTS: A total of 538 women had 1,076 pregnancies meeting inclusion criteria; 12/515 (2.3%) of women with a normal MSAFP, 28/470 (6.0%) with a normal hCG, and 11/504 (2.2%) with a normal E3 in the first pregnancy had an anomalous result for the respective analyte in the second pregnancy. In contrast, only 4/23 (17.4%) patients with an elevated MSAFP (P = 0.003), 14/44 (31.8%) with an elevated hCG (P < 0.001), and 2/10 (20.0%) with a low E3 (P < 0.025) in the first pregnancy had the same analyte anomaly recur in the second pregnancy. The odds ratios for recurrent elevated MSAFP, hCG, and low E3 were 7.5, 5.3, and 9.2, respectively. Adverse perinatal outcomes occurred with similar frequency, regardless of MSAFP, hCG, or E3 results in consecutive pregnancies, using women with normal MSAFP, hCG, and E3 results in one or both pregnancies as controls. CONCLUSIONS: Women experiencing an anomalous serum analyte in one pregnancy are at significant risk to experience the same analyte result in a subsequent pregnancy.     

alpha 2-Antiplasmin and alpha 2-macroglobulin--the main inhibitors of fibrinolysis--during the menstrual cycle, pregnancy, delivery, and treatment with oral contraceptives

alpha 2-Antiplasmin and alpha 2-macroglobulin have been studied during the menstrual cycle, pregnancy and parturition in healthy women, and during use of various types of contraception in both healthy and diabetic women, and compared with a reference group of healthy men and women. alpha 2-Antiplasmin showed a slight sex difference, with higher values in women. The luteal phase of the menstrual cycle showed slightly higher values than the other phases. alpha 2-Antiplasmin increased during pregnancy, decreased (probably due to consumption) during labor and increased again in the puerperium. Treatment with neither combined contraceptive pills nor low dose progestogen pills gave any changes in alpha 2-antiplasmin. alpha 2-Macroglobulin showed low values during menstruation. The increase during pregnancy and treatment with combined contraceptive pills is in accordance with earlier findings. It is concluded that synthesis and metabolism of alpha 2-antiplasmin are under hormonal influence. The role of alpha 2-antiplasmin in the decreased fibrinolysis in pregnancy is discussed.     

Fibrolamellar hepatocellular carcinoma arising in a background of focal nodular hyperplasia: a report of 2 cases

BACKGROUND: Fibrolamellar carcinoma, a rare variant of hepatocellular carcinoma, and focal nodular hyperplasia, a benign lesion, are rare hepatic lesions that are known to occur in young women with noncirrhotic livers. Some have suggested that fibrolamellar carcinoma might be the malignant counterpart of focal nodular hyperplasia. The coexistence of the 2 lesions is very rare. CASES: Two cases of fibrolamellar hepatocellular carcinoma arising in a background of focal nodular hyperplasia followed long-term oral contraception, and 1 of the 2 occurred during pregnancy. CONCLUSION: Distinguishing fibrolamellar carcinoma from focal nodular hyperplasia has important implications for treatment and prognosis. One should be aware of such conditions, especially in patients with a long history of oral contraception.     

Spontaneous Rupture of the Liver during Pregnancy: A Case Report

Hepatic congestion resulting in hepatic rupture during pregnancy is a rare yet catastrophic event carrying a 60 to 70% maternal mortality rate. With preeclampsia and associated epigastric pain continuing to be a major problem confronting pregnant women, hepatic congestion may be more prevalent than believed. Current etiology, treatment, and characteristics of women who experience hepatic rupture are examined. A case report and nursing protocol are presented.     

Using a logistic model to identify women with first-trimester spontaneous abortion suitable for expectant management

Objective To design a method to identify women with first trimester spontaneous abortion suitable for expectant management.
Design A stepwise logistic regression analysis based on retrospective analysis of clinical and biochemical variables.
Setting Department of Obstetrics and Gynaecology, Sahlgrenska University Hospital, Gothenburg, Sweden.
Participants One hundred and three women with inevitable or incomplete spontaneous abortion at < 13 weeks of gestation were chosen for expectant management. Eighty-one women with complete spontaneous abortion (i.e. complete expulsion and/or resolution of pregnancy products within three days of expectant management) were compared with those (   n = 22  ) who underwent surgical evacuation of the uterus, most commonly owing to retained products of conception after three days.
Results Employing a stepwise logistic regression procedure, five diagnostic variables possessing prognostic power were identified: serum progesterone, daily serum hCG change, serum CA125, serum alpha fetoprotein and intrauterine diameter. The logistic regression analysis was also applied to three diagnostic variables chosen for routine clinical use: serum progesterone, serum hCG and intrauterine diameter. The probability of complete spontaneous abortion within three days of expectant management in each woman could be calculated.
Conclusion We have used a logistic model to calculate the probability of complete spontaneous abortion within three days in women with first trimester miscarriages. Such information may be of clinical use in caring for women, as well as for development of management guidelines for those with miscarriages.     

Amniotic fluid alpha1fetoprotein in the diagnosis of neural tract malformations.

Amniotic fluid alpha1fetoprotein levels were determined in 400 pregnancies. The normal range for alpha1fetoprotein in amniotic fluid was defined by 350 samples from normal pregnancies. Elevated levels of alpha1fetoprotein were detected in 17 out of 18 pregnancies which gave rise to infants with neural tract abnormalities. The significance of this test in the antenatal diagnosis of neural tract abnormalities is discussed together with the possible reasons for "false negative" and "false positive" results. There were no complications in an individual series of 105 consecutive amniocenteses.     

Immunohistological localization of pregnancy-associated endometrial alpha 2-globulin (alpha 2-PEG) in endometrial adenocarcinoma and effect of medroxyprogesterone acetate

Endometrium from postmenopausal women with endometrial adenocarcinoma was examined immunohistochemically using a monoclonal antibody to pregnancy-associated endometrial alpha 2-globulin (alpha 2-PEG), the major secretory protein of the glandular epithelium during the late luteal phase of the menstrual cycle and early pregnancy. Specimens were obtained at initial diagnostic curettage and at hysterectomy after medroxyprogesterone acetate (MPA) therapy. alpha 2-PEG was not detected in any malignant tissue irrespective of histological differentiation. Non-malignant endometrium obtained in association with malignant tissue was negative for alpha 2-PEG before treatment although after MPA therapy all specimens obtained exhibited marked alpha 2-PEG localization in glands. In four specimens endogenous alkaline phosphatase was observed consistently only in the malignant endometrium. Malignant endometrium does not appear to synthesize alpha 2-PEG nor is its synthesis induced by an oral progestogen, so that it does not represent a useful marker for endometrial carcinoma. Non-malignant endometrium in postmenopausal women appears to be fully capable of alpha 2-PEG production after stimulation with an oral progestogen.     

Prediction and prevention of recurrent stillbirth

Stillbirth is one of the most common adverse pregnancy outcomes in the United States, occurring in one out of every 200 pregnancies. There is a paucity of information on the outcome of pregnancies after stillbirth. Prior stillbirth is associated with a twofold to 10-fold increased risk of stillbirth in the future pregnancy. The risk depends on the etiology of the prior stillbirth, presence of fetal growth restriction, gestational age of the prior stillbirth, and race. Categorization of the cause of the initial stillbirth will allow better estimates of individual recurrence risk and guide management. A history of stillbirth also increases the risk of other adverse pregnancy outcomes in the subsequent pregnancy such as placental abruption, cesarean delivery, preterm delivery, and low birth weight infants. Prospective studies have revealed an increased risk of stillbirth with low pregnancy-associated plasma protein A, elevated maternal serum alpha fetoprotein, abnormal uterine artery Doppler studies, and antiphospholipid antibodies. However, the positive predictive value of these factors individually is poor. Because fetal growth restriction is associated with almost half of all stillbirths, the correct diagnosis of fetal growth restriction is essential. The use of individualized or customized growth standards will improve prediction of adverse pregnancy outcome by distinguishing growth-restricted fetuses from constitutionally small, healthy fetuses. Antepartum fetal surveillance and fetal movement counting are also mainstays of poststillbirth pregnancy management.     

Therapy of endodermal sinus tumor of the ovary.

Endodermal sinus tumor of the ovary can be differentiated histologically and immunohistochemically from ovarian embryonal cell carcinoma. A case report of a patient with endodermal sinus tumor is presented in which a long-term remission was achieved by unilateral adnexectomy and combination chemotherapy. Review of the current literature indicates that tumor removal followed by combination chemotherapy with vincristine, actinomycin D, and cyclophosphamide is the most effective method of therapy for this highly malignant ovarian neoplasm. The addition of hysterectomy with contralateral ovariectomy or radiation therapy does not appear to significantly improve the survival of patients with this tumor. Serial plasma determinations of alpha fetoprotein provide biochemical monitoring of response to therapy and may be useful in predicting occult tumor recurrence.     

Continuous 24-hour secretion of growth hormone during late pregnancy. A regulator of maternal metabolic adjustment?

A dramatic change in growth hormone secretion was demonstrated during the 3rd trimester of human pregnancy, when compared with the non-pregnant state. The pulsatile pattern, with intermittent high peaks, and low or undetectable levels between peaks, characteristic of normal men and non-pregnant women, was completely abolished. All the 10 pregnant women investigated had the same stable basal circulating growth hormone concentration. Values were in the range 6-10 mU/l and there was no evidence of pulsatile activity. Previously, in animal experiments, a continuous secretion of growth hormone has been shown to 'feminize' hepatic steroid metabolism, hepatic prolactin receptors, hepatic sulphatase activity and to stimulate pregnancy protein synthesis. The same biological principle could be valid also during human pregnancy and be related to maternal metabolic adjustment.     

Factors affecting the uptake of screening for neural tube defect

A questionnaire concerning pregnant women's knowledge of, and attitudes to, serum alpha fetoprotein (AFP) screening for spina bifida was sent to all pregnant women receiving a health education leaflet on AFP screening who booked at the Birmingham Maternity Hospital in the first quarter of 1984. The majority said that they would accept the test, and subsequently did so. This suggests that low uptake of the test is not a result of patients' resistance, and the results indicated that the provision of early information about the test is likely to improve uptake and decrease anxiety. With the increasing clinical usefulness of the AFP test, routine screening of pregnant women with an 'opt-out' system is becoming clinically desirable, and the survey suggests that it would be acceptable to the patients.
