Preoperative differentiation of benign and malignant non-epithelial ovarian tumors: clinical features and tumor markers / Diferenciação pré-operatória de tumores ovarianos não epiteliais benignos e malignos: características clínicas e marcadores tumorais

Abstract Objective To evaluate the role of clinical features and preoperativemeasurement of cancer antigen 125 (CA125), human epididymis protein(HE4), and carcinoembryonic antigen (CEA) serum levels in women with benign and malignant non-epithelial ovarian tumors. Methods One hundred and nineteen consecutive women with germ cell, sex cordstromal, and ovarian leiomyomas were included in this study. The preoperative levels of biomarkers were measured, and then surgery and histopathological analysis were performed. Information about the treatment and disease recurrence were obtained from the medical files of patients. Results Our sample included 71 women with germ cell tumors (64 benign and 7 malignant), 46 with sex cord-stromal tumors (32 benign and 14 malignant), and 2 with ovarian leiomyomas. Among benign germ cell tumors, 63 were mature teratomas, and, amongmalignant, fourwere immatureteratomas. Themost common tumors in the sex cordstromal group were fibromas (benign) and granulosa cell tumor (malignant). The biomarker serum levels were not different among benign andmalignant non-epithelial ovarian tumors. Fertility-sparing surgeries were performed in 5 (71.4%) women with malignant germ cell tumor. Eleven (78.6%) patients with malignant sex cord-stromal tumors were treated with fertility-sparing surgeries. Five women (71.4%) with germ cell tumors and only 1 (7.1%) with sex cord-stromal tumor were treated with chemotherapy. One woman with germ cell tumor recurred and died of the disease and one woman with sex cord-stromal tumor recurred. Conclusion Non-epithelial ovarian tumors were benign in the majority of cases, and the malignant caseswere diagnosed at initial stages with good prognosis. Themeasurements of CA125, HE4, and CEA serum levels were not useful in the preoperative diagnosis of these tumors.

Métodos Cento e dezenovemulheres consecutivas comtumores ovarianos de células germinativas, do cordão sexual-estroma, e miomas ovarianos foram incluídas neste estudo. Os níveis pré-operatórios dos biomarcadores foram medidos, a cirurgia e a análise histopatológica foram realizadas. Informações sobre tratamento e recorrência da doença foram obtidas dos prontuários médicos das pacientes. Resultados Nossa amostra incluiu 71 mulheres com tumores de células germinativas (64 benignos e 7 malignos), 46 com tumores do cordão sexual-estroma (32 benignos e 14 malignos), e 2 com leiomiomas ovarianos. Entre os tumores benignos de células germinativas, 63 eram teratomas maduros, e, entre os malignos, quatro eram teratomas imaturos. Os tumores mais comuns do grupo do cordão sexual-estroma foram fibromas (benignos) e tumores de células da granulosa (malignos). Os níveis séricos dos biomarcadores não diferiram entre os tumores de ovário não epiteliais benignos e malignos. A cirurgia preservadora de fertilidade foi realizada em 5 (71,4%) mulheres com tumores malignos de células germinativas. Onze (78,6%) mulheres com tumores do cordão sexual-estromamalignos foram tratadas comcirurgia preservadora de fertilidade. Cinco (71,4%)mulheres com células germinativas e apenas 1 (7,1%) com tumor do cordão sexual-estroma foram tratadas com quimioterapia. Uma mulher com tumor de células germinativas recidivou e morreu da doença. Uma mulher com tumor do cordão sexual-estroma recidivou. Conclusão Os tumores de ovário não epiteliais foram benignos namaioria dos casos e os malignos foram diagnosticados em estágios iniciais, com bom prognóstico. A medida dos níveis séricos de CA125, HE4, e CEA não foram úteis no diagnóstico préoperatório desses tumores.

Laboratory predictors of survival in ovarian cancer

SUMMARY OBJECTIVE To relate disease-free survival and overall survival with type I and type II ovarian cancer and preoperative laboratory parameters biomarkers. METHODS A retrospective study was carried out based on the collection of data from medical records of patients with ovarian tumors. Kaplan-Mayer curves were drawn based on the statistical analysis of the data and were compared using the Log-rank test. RESULTS Disease-free survival in type I ovarian cancer was significantly higher than in type II (p=0.0013), as well as in those with normal levels of CA-125 (p=0.0243) and with a platelet-lymphocyte ratio (PLR) lower than 200 (p=0.0038). The overall survival of patients with type I ovarian cancer was significantly higher than in patients with type II, as well as in patients with normal CA-125 serum levels (p=0.0039) and those with a preoperative fasting glucose of less than 100 mg/dL. CONCLUSION CA-125 levels may predict greater overall and disease-free survival. PLR < 200 may suggest greater disease-free survival, whereas normal fasting glucose may suggest greater overall survival.

RESUMO OBJETIVO Relacionar a sobrevida livre de doença e sobrevida global com câncer de ovário tipos I e II, assim como com parâmetros laboratoriais pré-operatórios biomarcadores. MÉTODOS Estudo retrospectivo realizado com base na coleta de dados de prontuários de pacientes com tumor ovariano. As curvas de Kaplan-Mayer foram realizadas em relação à análise estatística dos dados, sendo comparadas pelo teste de Log-rank. RESULTADOS A sobrevida livre de doença nas pacientes com câncer de ovário tipo I foi significativamente maior do que nas pacientes com câncer de ovário tipo II (p = 0,0013), bem como maior naquelas com níveis normais de CA-125 (p = 0,0243) e com relação plaquetas-linfócitos (RPL) inferior a 200 (p = 0,0038). A sobrevida global de pacientes com câncer de ovário tipo I foi significativamente maior do que em pacientes com tipo II, maior em pacientes com níveis séricos normais de CA-125 (p = 0,0039) e naquelas com glicemia de jejum pré-operatória menor que 100 mg / dL. CONCLUSÃO Os níveis de CA-125 podem predizer uma sobrevida global e livre de doença. A RPL < 200 pode sugerir uma maior sobrevida livre de doença, enquanto uma glicemia normal de jejum, uma maior sobrevida global.

Mature Cystic Teratoma of Ovary with Abnormally High Levels of Ca19-9: A Case Report / Teratoma maduro cístico do ovário com níveis aberrantes de Ca19-9: caso clínico

Abstract Mature cystic teratomas, or dermoid tumors, are the most common benign ovarian neoplasms in young women. Malignant transformation is rare, and occurs in less than 2% of the cases. The heterogeneous histological composition of these tumors may be responsible for the occasional elevation of various tumor markers, such as Ca19-9 and Ca125. We describe one case of mature cystic teratoma in a 50-year old woman with the second highest level of Ca19-9 (8922.76 UI/mL) described in the literature. We concluded that abnormal levels of Ca19-9 are not necessarily associated with ovarian malignancy, and may lead to unnecessary medical intervention and patient anxiety. Therefore, the clinical features, imaging studies and antigen testing should be interpreted carefully, and should not limit the surgical approach.

Resumo Os teratomas maduros císticos do ovário, ou tumores dermoides, são as neoplasias benignas mais frequentes em mulheres jovens. A sua transformação maligna é rara, e ocorre emmenos de 2% dos casos. A composição histológica heterogénea destes tumores pode ser responsável pela ocasional elevação de marcadores tumorais, como o Ca19-9 e o Ca125. Descrevemos umcaso de teratoma maduro cístico do ovário numa paciente de 50 anos com o segundo valor mais elevado de Ca19-9 (8922,76 UI/mL) descrito na literatura. Concluímos que níveis anormalmente elevados de Ca19-9 não estão necessariamente associados a tumores malignos, e podem conduzir a intervenções médicas desnecessárias e contribuir para o aumento da ansiedade da paciente. Portanto, as características clínicas, os estudos imagiológicos e os marcadores tumorais devem ser interpretados cuidadosamente, e não devem limitar o tipo de conduta cirúrgica.

Comparison of survival outcomes after recurrence detected by cancer antigen 125 elevation versus imaging study in epithelial ovarian cancer / 부인종양

OBJECTIVE: The aim of this study was to compare survival outcomes in two groups of patients with recurrent epithelial ovarian cancer (EOC) with initial recurrence detection by cancer antigen 125 (CA-125) elevation or imaging, and underwent secondary cytoreductive surgery (SCS). METHODS: A retrospective review of the medical records was performed on 99 recurrent EOC patients who underwent SCS at the Samsung Medical Center between January 2002 and December 2013. For follow-up after primary treatment, patients were routinely assessed by CA-125 levels every 3 months and computed tomography (CT) scan (or magnetic resonance imaging [MRI]) every 6 months for first 3 years, and by CA-125 every 6 months and CT scan (or MRI) every 12 months thereafter. RESULTS: The first recurrence was initially identified by either CA-125 elevation (n=41, 41.4%) or by imaging study (n=58, 58.6%). None of the patients showed the symptoms as initial sign of recurrence. There were higher percentages of extra-pelvic recurrence (87.8%) and multiple recurrences (78.0%) in the group diagnosed by CA-125 elevation. The proportion of no residual disease after SCS was comparably lower in the CA-125 group (22.0% vs. 72.4%). There were 19 cancer-associated deaths (19.2%) within a median follow-up period of 67 months. The group diagnosed by imaging had better overall survival from initial diagnosis (OS1), overall survival after SCS (OS2), progression-free survival after the initial treatment (PFS1) and progression-free survival after SCS compared to those of the CA-125 group (PFS2). CONCLUSION: EOC patients with recurrence initially detected by imaging study showed better survival outcomes than patients diagnosed by CA-125 elevation.

Clinical Significance of CA125 Level after the First Cycle of Chemotherapy on Survival of Patients with Advanced Ovarian Cancer

PURPOSE: To determine the most powerful cancer antigen 125 (CA125)-related prognostic factor for advanced epithelial ovarian cancer (EOC) and to identify cut-off values that distinguish patients with a poor prognosis from those with a good prognosis. MATERIALS AND METHODS: We included 223 patients who received staging laparotomy and were diagnosed with stage IIC-IV serous EOC. Cox regression analysis was used to determine the most significant prognostic factor among the following variables: serum CA125 before surgery and after the first, second, and sixth cycles of chemotherapy; the nadir CA125 value; the relative percentage change in CA125 levels after the first and second cycles of chemotherapy compared to baseline CA125; CA125 half-life; time to nadir; and time to normalization of the CA125 level. RESULTS: The CA125 level after the first chemotherapy cycle was the most significant independent prognostic factor for overall survival (OS). Time to normalization (p=0.028) and relative percentage change between CA125 levels at baseline and after the first chemotherapy cycle (p=0.021) were additional independent prognostic factors in terms of OS. The CA125 level after the first chemotherapy cycle (p=0.001) and time to normalization (p<0.001) were identified as independent prognostic factors for progression free survival (PFS). CONCLUSION: Among well-established CA125-related prognostic factors, serum CA125 levels after the first cycle of chemotherapy and time to normalization were the most significant prognostic factors for both OS and PFS.

Evaluation of oral-motor movements and facial mimic in patients with head and neck burns by a public service in Brazil

OBJECTIVES: The purpose of this study was to analyze the characteristics of oral-motor movements and facial mimic in patients with head and neck burns. METHODS: An observational descriptive cross-sectional study was conducted with patients who suffered burns to the head and neck and who were referred to the Division of Orofacial Myology of a public hospital for assessment and rehabilitation. Only patients presenting deep partial-thickness and full-thickness burns to areas of the face and neck were included in the study. Patients underwent clinical assessment that involved an oral-motor evaluation, mandibular range of movement assessment, and facial mimic assessment. Patients were divided into two groups: G1 - patients with deep partial-thickness burns; G2 - patients with full-thickness burns. RESULTS: Our final study sample comprised 40 patients: G1 with 19 individuals and G2 with 21 individuals. The overall scores obtained in the clinical assessment of oral-motor organs indicated that patients with both second- and third-degree burns presented deficits related to posture, position and mobility of the oral-motor organs. Considering facial mimic, groups significantly differed when performing voluntary facial movements. Patients also presented limited maximal incisor opening. Deficits were greater for individuals in G2 in all assessments. CONCLUSION: Patients with head and neck burns present significant deficits related to posture, position and mobility of the oral myofunctional structures, including facial movements. .

Comparison of HE4, CA125, and Risk of Ovarian Malignancy Algorithm in the Prediction of Ovarian Cancer in Korean Women

This study is a multi-center clinical study, which aimed to compare CA125, HE4, and risk of ovarian malignancy algorithm (ROMA) in predicting epithelial ovarian cancer of Korean women with a pelvic mass. Prospectively, serum from 90 Korean women with ovarian mass was obtained prior to surgery. For control group, serum from 79 normal populations without ovarian mass was also obtained. The HE4 and CA125 data were registered and evaluated separately and ROMA was calculated for each sample. Total 67 benign tumors and 23 ovarian cancers were evaluated. Median serum levels of HE4 and CA125, and ROMA score were significantly higher in patients with ovarian cancer than those with benign ovarian tumor and normal population (P < 0.001). In ROC curve analysis for women with a pelvic mass, area under the curve (AUC) for HE4 and ROMA was higher than CA125. Statistical differences in each study compared to CA125 were marginal (P compared to CA125; 0.082 for HE4 and 0.069 for ROMA). Sub-analysis revealed that AUC for HE4 and ROMA was higher than AUC for CA125 in post-menopausal women with a pelvic mass, but there were no statistically significant differences (P compared to CA125; 0.160 for HE4 and 0.127 for ROMA). Our data suggested that both HE4 and ROMA score showed better performance than CA125 for the detection of ovarian cancer in women with a pelvic mass. HE4 and ROMA can be a useful independent diagnostic marker for epithelial ovarian cancer in Korean women.

Ginandroblastoma multiloculado, negativo para CD99 en una niña de 12 años: caso clínico / A twelve-years-old girl with multiloculated gynandroblastoma CD99 negative. Case report

Los ginandroblastomas son tumores del ovario extremadamente raros, los cuales comparten componentes de células de la granulosa y de células de Sertoli/Leydig. Se describe un caso de una niña de 12 años, quien presenta hemorragia uterina anormal y sensación de masa intraabdominal de crecimiento progresivo asociado a menorragia, niveles de CA-125 en 60,4 UI/mL y estudios de extensión que reportan masa quística en ovario izquierdo, manejada con ooforectomía. El estudio anatomopatológico muestra un tumor multiloculado lleno de material seroso, abundantes cuerpos de Call-Exner y 45% de células de Sertoli/Leydig. La inmunohistoquímica reveló inmunorreactividad para inhibina, calretinina y pCK, mientras que los marcadores CD99 y AE1/AE3 fueron negativos. Se trata del primer reporte de caso sobre un ginandroblastoma multiloculado, negativo para CD99 en una niña de 12 años, estudio que plantea un abordaje sistemático para los tumores de las células de los cordones sexuales.

The ginandroblastoma is an extremely rare ovarian tumor which shows components of granulosa cells and Sertoli/Leydig cells. We describe a case of a twelve-years-old girl who presented abnormal uterine bleeding and progressively growing intra- abdominal mass associated with menorrhagia, CA-125 60.4 UI/mL and extension studies reporting cystic mass in the left ovary. She underwent oophorectomy. Pathological study shows a multilocular tumor filled with serous material. Many Call-Exner bodies were observed in the histopathological analysis, 45% of Sertoli/Leydig cells. Immunohistochemistry was reactive for inhibin, calretinin and pCK while AE1/AE3 and CD99 markers were negative. This is the first case report about a multiloculated gynandroblastoma, negative for CD99 in a 12-years-old girl. Thus, the study of this clinical case represents a systematic approach for tumors of the sex cord cells.

Ovarian Leydig cell tumor in a post-menopausal patient with severe hyperandrogenism / Tumor ovariano de células de Leydig em paciente em pós-menopausa com hiperandrogenismo grave

Leydig cell tumors are rare ovarian steroid cell neoplasms. More than 75% of patients show signs of virilization due to overproduction of testosterone. We report a case of an 8-year-old woman with progressive signs of virilization, and presenting vaginal bleeding. Clinical analyses revealed high levels of serum testosterone, delta 4-androstenedione and estradiol, and also inappropriate low levels of gonadotrophins for a post-menopausal woman. Transvaginal ultrasound showed no evidence of ovarian tumor, but pelvic and abdominal computerized axial tomography imaging revealed a left ovarian solid nodule, and no evidence of alteration in the adrenal glands. Total hysterectomy and bilateral salpingoophorectomy were performed. Histopathology and immunohistochemistry confirmed the diagnosis of Leydig cell tumor. After surgery, androgen levels returned to normal, and there was regression of the signs of virilization.

Tumores ovarianos de células de Leydig são neoplasias raras de células ovarianas esteroidogênicas. Mais de 75% dos pacientes apresentam sinais de virilização devido à produção excessiva de testosterona. Relatamos aqui o caso de uma mulher de 81 anos de idade com sinais progressivos de virilização e ocorrência de sangramento vaginal. As análises clínicas mostraram altos níveis de testosterona sérica, delta 4-androstenediona e estradiol, além de níveis inadequadamente baixos de gonadotrofinas para uma mulher em pós-menopausa. O ultrassom transvaginal não apresentou evidências de tumor ovariano, mas a tomografia axial computadorizada da região pélvico-abdominal mostrou um nódulo sólido no ovário esquerdo e nenhuma evidência de alteração nas adrenais. Foi feita uma histerectomia total e salpingooforectomia bilateral. Os exames histopatológicos e a imuno-histoquímica confirmaram o diagnóstico de tumor de células de Leydig. Após a cirurgia, os níveis de androgênios voltaram ao normal, e os sinais de virilização regrediram.

El sistema lewis hoy. nuevos enfoques / The lewis system today. new approaches

La expresión de antígenos (Ags) Lewis depende de alelos heredados en loci independientes, el gen Secretor (SE) que codifica la fucosiltransferasa 2 (FUT2) y el gen Lewis (LE) que codifica la fucosiltransferasa 3 (FUT3). El gen Se codifica una glicosiltransferasa que adiciona una fucosa en la cadena precursora de tipo 1 formando el Ag H en secreciones y fluidos. Como los azúcares inmunodominantes del Ag A y B pueden ser agregados a la cadena H de tipo 1, la FUT2 también controla la expresión de Ag A y B en las secreciones. El gen se es un alelo no funcional. El gen Le codifica una transferasa diferente que adiciona una fucosa en el 2do carbono en el precursor de tipo 1. El alelo le no es funcional. Las FUT2 y FUT3 interactúan para la formación de Ags Lewis en secreciones y fluídos. Los Ags Lewis en los eritrocitos no son en realidad parte integral de la membrana, están adsorbidos sobre la superficie en forma pasiva a partir del plasma. Están ampliamente distribuidos en tejidos humanos, eritrocitos, endotelio, riñón, tracto genitourinario, epitelio gastrointestinal y son receptores para algunos patógenos. Los anticuerpos (Acs) anti-Lewis en general no son clínicamente significativos, aunque se han publicado algunos casos de reacciones transfusionales hemolíticas, enfermedad hemolítica fetoneonatal y rechazo de transplante renal. Este trabajo es una revisión sobre los Ags del Sistema Lewis enfocada hacia sus diferentes funciones biológicas y su importancia en campos variados fuera del Banco de Sangre y la Inmunohematología tradicional.

The expression of Lewis blood group antigens depends on the alleles inherited at independent loci, FUT2 Secretor gene (SE) and FUT3 Lewis gene (LE). The Se and Le alleles encode separate fucosyltransferases that interact to form Lewis antigens in secretions and fluids. The Lewis antigens on red blood cells are not integral to the membrane but are passively adsorbed from the plasma. The allele Se encodes a transferase that adds fucose to type 1 precursor chains in secretions and fluids to form type 1 H antigen. Because A and B terminal sugars may be added to type 1 H chains, FUT2 also controls A and B expression in secretions. The FUT2 allele se gen is a nonfunctional allele. The FUT3 allele Le encodes a transferase that adds a fucose in other position in type 1 H precursor. The FUT3 allele le gen is a nonfunctional allele. The Le antigens are widely distributed in human tissues and fluids and are receptors for some pathogenic organisms. Lewis antibodies are rare and clinically no significant, although there are some reports of hemolytic transfusion reactions, hemolytic disease of the newborn and renal transplant rejection. This review focuses on different biological functions of Lewis antigens and their importance in some fields other than Blood Banks and traditional.

Role of 18F-fluorodeoxy glucose PET-CT in asymptomatic epithelial ovarian cancer with rising serum CA-125: A pilot study.

Background. We evaluated the role of 18F-fluorodeoxy glucose (FDG) PET-CT scan in the diagnosis of early relapse in patients with epithelial ovarian cancer (EOC) who were asymptomatic but had a rising serum CA-125 level. Methods. Between May 2006 and July 2008, 16 patients with advanced EOC (stages III and IV) who had achieved complete response after cytoreductive surgery and platinumbased chemotherapy were included. These patients were asymptomatic but had a rising serum CA-125 level with normal physical examination and contrast-enhanced CT scan of the abdomen and pelvis. Patients were evaluated with 18F-FDG PET-CT scan. Written informed consent was taken. Patients with a positive PET-CT scan were advised ultrasoundguided fine-needle aspiration cytology (FNAC) from the area showing increased uptake. Patients in whom FNAC was negative or inconclusive or those with negative PET-CT scan were followed up closely for the next 6 months with repeat clinical evaluation and CT scan. Results. Fifteen patients (15/16) had a positive PET-CT scan. In 9 patients the positive PET lesion was confirmed on FNAC, while in 5 patients this was confirmed on follow-up CT scan after 6 months. One patient who had a single positive lesion in the pelvis on PET-CT was initially considered falsepositive because a follow-up CT scan at 6 months did not show the lesion. However, on regular follow-up after 2 years, she was detected to have an isolated lesion in the PET-positive area which was confirmed on secondary cytoreduction. This patient was considered as true-positive in the current analysis. One patient, who had a negative PET-CT scan and a negative CT scan at 6 months’ follow-up was considered true-negative. The sensitivity and specificity of PET-CT scan was 100%. We could confirm positivity on histopathology/FNAC in 10 of the 15 (66.7%) true-positive cases. Conclusion. 18F-FDG PET-CT scan is a sensitive and specific technique for early diagnosis of relapse in asymptomatic EOC patients with rising CA-125. However, its role in the management of recurrent ovarian cancers needs further evaluation.

Tumor estromal esclerosante de ovário associado à síndrome de Meigs e gestação: relato de caso / Sclerosing stromal tumor of the ovary associated with a Meigs' syndrome and pregnancy: a case report

O tumor estromal esclerosante de ovário é uma neoplasia benigna extremamente rara, mais frequente em mulheres jovens e sem sintomas específicos na maioria dos casos. Menos de 150 casos foram descritos, dos quais 8 diagnosticados durante a gestação. Neste relato, documentamos a associação entre tumor estromal esclerosante de ovário, síndrome de Meigs e elevação dos níveis de CA-125 em gravidez a termo.

The sclerosing stromal tumor of the ovary is an extremely rare benign tumor more common in young women and without specific symptoms in most cases. Less than 150 cases have been described, of which 8 were diagnosed during pregnancy. In this report, we describe the association between sclerosing stromal tumor of the ovary, Meigs' syndrome and elevated levels of CA-125 in term pregnancy.

Potencial herramienta en la personalización del tratamiento oncológico: Casos clínicos / In vitro cell response to chemotherapeutic agents, to personalize ovarian cancer treatment: Report of two cases

Our laboratory has implemented an in vitro assay to estimate the response to chemotherapy in ovarian cancer cells pertaining to individual patients. In two selected patients, we determined the correlation between an in vitro assay of cells from suspected ovarian cancer ascites, with the clinical chemotherapy response. Cancer cells isolated from peritoneal fluid with suspected ovarian cancer were tested for cytotoxicity with corresponding chemotherapy regimens. Circulating Cal25 levels and attending physician consultation determined clinical course and response to chemotherapy. The in vitro assay result correlated with Cal25 levels, progression free survival and attending physician evaluation. The assay predicted correctly the failure of two successive chemotherapy regimes in the first patient, while predicting a favorable clinical response in the second subject.

Preoperative Serum Anti-Mullerian Hormone Level in Women with Ovarian Endometrioma and Mature Cystic Teratoma

PURPOSE: To investigate whether preoperative serum anti-mullerian hormone (AMH) levels are lower in women with ovarian endometrioma and in women with mature cystic teratoma of the ovaries. MATERIALS AND METHODS: In a tertiary university hospital, a retrospective case-control study was performed. Serum AMH levels between an advanced (stage III and IV) endometrioma group (n=102) and an age- and body mass index (BMI)-matched control group were compared. Serum AMH levels between an ovarian mature cystic teratoma group (n=48) and age- and BMI-matched controls were also compared. RESULTS: Absolute serum AMH and multiples of the median for AMH (AMH-MoM) relevant to Korean standards were lower in the endometrioma group than controls, but this was not statistically significant (mean+/-SEM, 2.9+/-0.3 ng/mL vs. 3.3+/-0.3 ng/mL, p=0.28 and 1.3+/-0.1 vs. 1.6+/-0.1, p=0.29, respectively). Specifically, the stage IV endometriosis group (n=51) exhibited significantly lower serum AMH and AMH-MoM (2.1+/-0.3 vs. 3.1+/-0.4 ng/mL, p=0.02 and 1.1+/-0.1 vs. 1.7+/-0.2, p=0.03, respectively). Serum AMH and AMH-MoM levels were similar between stage III endometriosis and controls (3.7+/-0.5 vs. 3.4+/-0.5 ng/mL and 1.6+/-0.2 vs. 1.5+/-0.2, respectively), as well as between the mature cystic teratoma group and controls (4.0+/-0.5 ng/mL vs. 4.0+/-0.5 ng/mL and 1.6+/-0.2 vs. 1.6+/-0.3, respectively). Interestingly, AMH-MoM level was negatively correlated with endometriosis score with statistical significance (r2=0.13, p<0.01). CONCLUSION: In women with advanced ovarian endometrioma, preoperative serum AMH values tended to be lower than those for age and BMI-matched controls. Notably, stage IV endometrioma appeared to be closely associated with decreased ovarian reserve, even before operation. Clinicians should keep this information in mind before undertaking surgery of ovarian endometrioma.

Clinical Significance of Serum CA-125 in Korean Females with Ascites

PURPOSE: Mycobacterium tuberculosis is endemic in Korea. Because tuberculous peritonitis is characterized by ascites, abdominal pain, abdominal mass and elevation of serum CA-125, it can be confused with ovarian malignancies. The aim of this study was to evaluate the significance of serum CA-125 level in the differential diagnosis of tuberculous peritonitis and ovarian malignancy in a Mycobacterium tuberculosis-endemic area. MATERIALS AND METHODS: The medical records of patients diagnosed with tuberculous peritonitis (n=48) or epithelial ovarian malignancy (n=370) at Samsung Medical Center from January 2000 to October 2009 were retrospectively reviewed. RESULTS: Median serum CA-125 level in the epithelial ovarian cancer group was significantly higher than that in the tuberculous peritonitis group (p< or =0.01). Only one patient (2.1%) in the tuberculous peritonitis group had a serum CA-125 level over 2000 U/mL. However, 109 patients (29.5%) in the epithelial ovarian cancer group had a serum CA-125 level over 2000 U/mL. At the CA-125 ranges of 400 to 599 and 600 to 799, the proportions of those with tuberculous peritonitis were 24% and 21.9%, respectively. At a serum CA-125 level over 1000 U/mL, however, the proportion of tuberculous peritonitis was much lower (2.1%). CONCLUSION: Tuberculous peritonitis should be considered in the evaluation of female patients with ascites and high serum CA-125.

Serum ca-125 versus ultrasound examination in differentiating between benign and malignant ovarian masses

To differentiate between benign and malignant ovarian masses by using serum CA125 versus ultrasound examination. This descriptive study was conducted at Department of Obstetrics and Gyneecology, Hayatabad Medical Complex from 1[st] January 2010 to 31[st] December 2010. Women fulfilling inclusion criteria were admitted. They underwent transabdominal gray-scale ultrasound examinations by an experienced examiner before surgery. Pattern recognition was used to classify a mass as benign or malignant. These women also had blood withdrawn preoperatively for measurement of serum CA-125 with cut off value of < 35 IU as normal. Results from both radiological finding and serum CA125 were then compared with histopathological findings which was used as gold standard. Pattern recognition by ultrasound correctly classified 69.64% of the tumors as benign or malignant. Serum CA-125 correctly classified at best 74.14% of the masses. Combining both parameters the diagnostic accuracy increased to 86.75% with sensitivity 80.36%, specificity 100%, positive predictive value 100% and negative predictive value of 71.05%. Pattern recognition alone was inferior to serum CA-125. Combining both parameters for differentiating between benign and malignant ovarian masses further increased the diagnostic accuracy

The Serum CA-125 Concentration Data Assists in Evaluating CT Imaging Information When Used to Differentiate Borderline Ovarian Tumor from Malignant Epithelial Ovarian Tumors

OBJECTIVE: We wanted to evaluate the diagnostic value of serum CA-125 concentration, when used in combination with the preoperative contrast-enhanced CT results, to differentiate borderline ovarian tumors (BOTs) from stage I malignant epithelial ovarian tumors (MEOTs). MATERIALS AND METHODS: Ninety-eight masses (46 BOTs and 52 stage I MEOTs) from 87 consecutive patients (49 with BOTs and 38 with stage I MEOTs) who had undergone preoperative contrast-enhanced computed tomography (CT) and surgical staging were evaluated retrospectively and independently by two radiologists. The preoperative serum CA-125 concentration was measured in all patients. The utility of analyzing serum CA-125 concentration in combination with the CT results was evaluated by receiver operating characteristic (ROC) curve analysis. RESULTS: An irregular tumor surface and lymphadenopathy were predictive of a MEOT. ROC analysis showed that the combination of CT data and the serum CA-125 level resulted in a higher diagnostic performance than did using the CT alone for differentiating BOTs from MEOTs. The areas under the curves (AUCs) without and with the use of the serum CA-125 level data were 0.67 (95% confidence interval [CI]: 0.57-0.77) and 0.78 (95% CI: 0.68-0.85), respectively, for reader 1 (p = 0.029) and 0.71 (95% CI: 0.61-0.80) and 0.81 (95% CI: 0.72-0.89), respectively, for reader 2 (p = 0.009). CONCLUSION: The serum CA-125 concentration is of additional diagnostic value when used in conjunction with the CT imaging results for differentiating BOTs from MEOTs.

Serum HER2 level in epithelial ovarian cancer

The proto-oncogene HER2 plays a key role in the control of cellular proliferation. Its overexpression has been reported to be associated with a poor prognosis in cancer, particularly in breast cancer. In the present study, serum HER2 levels were investigated in patients diagnosed with epithelial ovarian cancer. Serum HER2 levels were detected by an ELISA commercial kit in 51 patients and 33 healthy individuals. The mean serum HER2 level was found to be significantly higher in patients than healthy controls [P=0.005]. In 29% of patients, serum HER2 levels were higher than the cut-off value. HER2 serum level was not associated with tumor stage at diagnosis. Elevation of HER2 in a high proportion of patients with epithelial ovarian cancer further strengthens the importance of this molecule in the pathogenesis of ovarian cancer

[Assessment of serum LH, FSH /tumor fluid FSH, LH ratio in ovarian tumors]

As ovarian cancers are prevalent and have a high mortality rate, early diagnosis is important. Markers that detect ovarian malignancies earlier, include the levels of serum and ovarian cyst fluid gonadotropins. This study was performed in Imam Hossein hospital between 2008 and 2010 to determine the diagnostic value of the ratio of serum to ovarian cyst fluid gonadotropins in defining the type of ovarian tumors. This cross-sectional study was performed on patients operated because of ovarian mass. Their serum samples and cyst fluid were collected at the time of laparatomy and the histopathologic diagnosis was established after removal of the tumor. FSH and LH concentration were measured in serum and tumor fluid by Microparticle Enzyme Immunoassay technology in Imam Hossein laboratory and the ratios of serum FSH and LH to the cyst fluid gonadotropins were determined in four pathologic groups [simple cyst, benign, borderline and malignant]; statistical comparison was done with the Kruskal-Wallis and Mann-Whitney U-test. We studied 100 patients with ovarian masses; in 79 patients pathology was reported as epithelial tumors and simple cysts. The most common mass were simple cysts [48.1%], followed by benign tumors [27.8%], malignant tumors [16.5%] and borderline tumors [7.6%]. Serum FSH/ tumor fluid ratios were, 21.1 +/- 53.8 in simple cysts, 50.7 +/- 174.9 in benign tumors, 1.5 +/- 0.7 in borderline tumors and 1.9 +/- 1.9 in malignant tumors [P<0.001]. Serum LH/tumor fluid ratios were 12.1 +/- 26.5 in simple cysts, 20.0 +/- 29.1 in benign tumors, 2.6 +/- 2.3 in borderline tumors and 2.8 +/- 3.7 in malignant tumors [P<0.002]. Our findings suggest that serum/tumor fluid gonadotropins ratio can be used as a tumor marker for identification of ovarian tumors

Ovarian Thecoma with Virilizing Manifestations

A 29-year-old woman presented with secondary amenorrhea, primary infertility, and virilization, which had developed over the past 2 years was suspected to have a virilizing tumor at her left ovary. Her serum testosterone level was markedly elevated (380 ng/dL). Left salpingooophorectomy was performed, and histopathological examination revealed a thecoma of the left ovary. The postoperative serum testosterone level returned to 65 ng/dL. The patient did not have regression of virilism soon. However, the patient had a normal menstruation 29 days after surgery and gave birth to a baby 13 months after surgery.
