Abstract
BackgroundIn this retrospective study, we discuss our experience as a large tertiary referral center in Egypt in the management and follow-up of borderline tumorsPatients and methodsThis is a retrospective cohort study where all patients diagnosed with a borderline ovarian tumor at Oncology Center Mansoura University from November 2014 to June 2020 were included. Demographics, preoperative, operative, postoperative, pathologic, and oncologic follow-up data were retrieved from a prospectively maintained electronic database. The included patients were followed until April 2022.ResultsWe included 27 patients with borderline ovarian tumors. The mean age of the study patients was 47.67 ± 16.39 years. The median CA 125 was 33 (6–304 U/ml). Frozen section examination was utilized in 13 patients (48.14%), where a diagnosis of borderline ovarian tumors was revealed in 8 patients. Recurrence was reported in one patient with serous type after approximately 26 months. The most common pathological type in our cohort was the mucinous borderline type reported in 14 patients (51.9%), followed by the serous type reported in 11 patients (40.7%), and the seromucinous type in 1 patient only. Patients with mucinous borderline type were significantly younger (40.083 ± 18.47 vs. 53.73 ± 11.91 years, p = 0.028). Interestingly, Cancer Antigen 125 levels were significantly higher in mucinous than serous and seromucinous types [67(16–304) vs. 20(6–294.6) U/ml, p = 0.027]. On the other hand, the radiological tumor size of serous and seromucinous types was larger than that of the mucinous type [23(19–31) cm vs. 8(5–20) cm, p = 0.001]. Over a median follow-up period of 58.66 (54.16–63.16) months, only one postoperative mortality was reported, while only one recurrence was reported.ConclusionBorderline ovarian tumors still represent a dilemma either in diagnosis or management. A frozen section examination could help to reach a preliminary diagnosis. Total abdominal hysterectomy and bilateral salpingo-oophorectomy are the cornerstone of surgical management; however, fertility-sparing surgery could be a valid option for women desiring fertility.

Abstract
PURPOSE To characterize and investigate PET/CT findings in the omentum in the differentiation of tuberculous peritonitis (TBP) and peritoneal carcinoma (PC). METHODS Thirty-nine patients with TBP and 113 patients with PC who underwent PET/CT were retrospectively enrolled. The omental uptake intensity, distribution characteristics, contracture, size and boundary of soft-tissue lesions, and CT patterns were reviewed. RESULTS Absent and focal FDG uptake in the lesser omentum was more common in the PC patients (P = 0.034 and P = 0.017, respectively), and diffuse FDG uptake in the lesser omentum was more common in the TBP patients (P < 0.001). An apron-like pattern in the greater omentum commonly occurred in the TBP patients (P = 0.004). Micronodules (< 5 mm) were more common in the TBP patients (P < 0.001), and masses (> 3 cm) were more common in the PC patients (P = 0.001). Smudged and nodular patterns occurred more frequently in the TBP patients than in the PC patients (P < 0.001 and P = 0.003, respectively), and the caked pattern occurred more frequently in the PC patients (P < 0.001). There was no significant difference in the FDG uptake intensity and the boundary of soft-tissue lesions between the TBP and PC patients (P = 0.191 and P = 0.061, respectively). CONCLUSION Diffuse FDG uptake, an apron-like pattern, micronodules, and a smudged and nodular pattern might be significant differential features of TBP. Absent and/or focal FDG uptake, mass, and a caked pattern might be significant differential features of PC.

Abstract
Current biomarkers did not overcome the limitations of clinical application due to the heterogeneity of ovarian tumors. The role of nuclear factor of activated T cells (NFAT) in the prognosis of different histological subtypes of ovarian cancer remains unclear. NFAT expression was analyzed in 302 ovarian tumors from The Cancer Genome Atlas (TCGA) dataset and was further confirmed by 88 ovarian tumor specimens, including 30 clear-cell carcinoma, 34 serous carcinoma, and 24 papillary serous cystadenocarcinoma. The correlations between NFAT expression, cancer biomarkers, and clinical characteristics in different subtypes of ovarian tumors were analyzed. ALGGEN PROMO, reporter assay, and NFAT overexpression and knockdown were used to identify chondroadherin (CHAD) as the downstream target of NFAT. NFAT was significantly upregulated only in late-stage clear-cell carcinoma, but not in other two subtypes. NFAT levels were correlated with CA72-4 levels and poor overall survival and disease-free survival (P < 0.05), suggesting that NFAT together with CA72-4 were specific prognostic markers for clear-cell carcinoma. Pathological stage and lymph node metastasis were the prognostic factors affecting serous carcinoma (P < 0.05), while CA-125 was the prognostic factor affecting papillary serous cystadenocarcinoma (P < 0.05). PROMO and reporter assay indicated that CHAD was the downstream target of NFAT. In addition, NFAT overexpression and silencing increased and reduced CHAD expression, respectively. NFAT together with CA72-4 were specific tumor markers for risk assessment of unique clear-cell subtype of ovarian tumors. CHAD was identified as the downstream target gene of NAFT and was associated with poor survival of ovarian cancer.

Abstract
BACKGROUND Tumor markers are useful for detection and preoperative evaluation of ovarian tumors. We evaluated the clinical usefulness of cancer antigen (CA) 125, human epididymis 4 (HE4), and CA72-4 levels and Risk of Ovarian Malignancy Algorithm (ROMA) values for differential diagnosis of malignant and borderline tumors among suspected ovarian tumors, and the effects of endometriosis on these tumor markers. METHODS In a total of 266 patients (213, 14, and 39 with benign, borderline and malignant tumors, respectively), CA125, HE4, and CA72-4 levels were measured, and ROMA values were calculated. Medians of each marker were compared among the three groups. The area under the ROC curve (AUC), sensitivity, and specificity were calculated to analyze the diagnostic performance of each marker. RESULTS All markers were significantly higher in the malignant group than in the benign group. HE4 levels and ROMA values were significantly higher in the malignant group than in the borderline group. ROMA value had the highest AUC for distinguishing the malignant and borderline groups from the benign group in premenopausal (0.773) and postmenopausal (0.927) patients. CA125 level was significantly higher in patients with endometriosis than in those without (P<0.001), whereas HE4 and CA72-4 levels were not affected by endometriosis (P=0.128 and 0.271, respectively). CONCLUSIONS ROMA value is the best marker to distinguish malignant and borderline tumors from benign tumors in pre- and postmenopausal patients. HE4 and CA72-4 levels provide information on possible CA125 elevation due to endometriosis.

Abstract
OBJECTIVES To evaluate the diagnostic value of serum biomarkers in the management strategy of borderline ovarian tumours (BOT) to make management recommendations. METHODS English and French review of literature from 1990 to 2019 based on publications from Pubmed, Medline, Cochrane, with keywords: borderline ovarian tumors, tumour markers, CA125, CA19 9, ACE, CA72 4, TAG72, HE4, ROMA, mucinous, serous, mucinous, endometrioid ovarian tumours, peritoneal implants, recurrence, overall survival, follow-up. Among 1000 references, 400 were selected and only 30 were screened for this work. RESULTS Literature review: there is low evidence in literature concerning the discriminating value of serum tumour biomarkers (CA125, CA19-9, CEA, CA72-4, HE4) and specific score between presumed benign ovarian tumour/BOT/ovarian cancer (LE4). Serum CA125 antigen is higher in case of serous borderline ovarian tumour (LE4), increase with the tumor height, the FIGO stage, notably in case of serous borderline ovarian tumor. However, a normal value rate of serum CA125 antigen does not rule out a BOT (LE4). The preoperative positivity rate of CA19 9 in case of TFO is relatively lower than that of CA125 and is higher in mucinous TFO. The preoperative rate of serum CA19 9 antigen increases with the tumour height and the FIGO stage (LE4) and are higher in case of mucinous BOT (LE4). Preoperative rates of serum HE4 are not different between histologic type of BOT. A high level of serum biomarkers (CA125) is a predictive factor of peritoneal implants (LE4) and an independent predictive factor of recurrence (CA125) (LE4). RECOMMENDATIONS no recommendation can be made about the use of serum tumour biomarkers (CA125, CA19-9, CEA, CA72-4, HE4) or specific score in order to distinguish benign ovarian tumor/borderline ovarian tumor/ovarian cancer in case of indeterminate mass. In case of suspicion of mucinous ovarian tumour on imaging, the systematic dosage of serum CA19-9 antigen can be proposed (grade C). In case of an ovarian indeterminate mass on imaging; dosage of serum HE4 and C125 is recommended. If preoperative dosage of serum tumor biomarkers is normal, their systematic dosage is not recommended in the follow-up of BOT (grade C). If preoperative dosage of CA125 is high, the systematic dosage of CA125 is recommended in the follow-up of BOT with no precisions about the rhythm and the duration of the follow-up (grade B).

Abstract
OBJECTIVE To provide clinical practice guidelines from the French college of obstetrics and gynecology (CNGOF) based on the best evidence available, concerning epidemiology of recurrence, the risk or relapse and the follow-up in case of borderline ovarian tumor after primary management, and evaluation of completion surgery after fertility sparing surgery. MATERIAL AND METHODS English and French review of literature from 2000 to 2019 based on publications from PubMed, Medline, Cochrane, with keywords borderline ovarian tumor, low malignant potential, recurrence, relapse, follow-up, completion surgery. From 2000 up to this day, 448 references have been found, from which only 175 were screened for this work. RESULTS AND CONCLUSION Overall risk of recurrence with Borderline Ovarian Tumour (BOT) may vary from 2 to 24% with a 10-years overall survival>94% and risk of invasive recurrence between 0.5 to 3.8%. Age<40 years (level of evidence 3), advanced initial FIGO stage (LE3), fertility sparing surgery (LE2), residual disease after initial surgery for serous BOT (LE2), implants (invasive or not) (LE2) are risk factors of recurrence. In case of conservative treatment, serous BOT had a higher risk of relapse than mucinous BOT (LE2). Lymphatic involvement (LE3) and use of mini invasive surgery (LE2) are not associated with a higher risk of recurrence. Scores or Nomograms could be useful to assess the risk of recurrence and then to inform patients about this risk (gradeC). In case of serous BOT, completion surgery is not recommended, after conservative treatment and fulfillment of parental project (grade B). It isn't possible to suggest a recommendation about completion surgery for mucinous BOT. There is not any data to advise a frequency of follow-up and use of paraclinic tools in general case of BOT. Follow-up of treated BOT must be achieved beyond 5 years (grade B). A systematic clinical examination is recommended during follow-up (grade B), after treatment of BOT. In case of elevation of CA-125 at diagnosis use of CA-125 serum level is recommended during follow-up of treated BOT (grade B). When a conservative treatment (preservation of ovarian pieces and uterus) of BOT is performed, endovaginal and transabdominal ultrasonography is recommended during follow-up (grade B). There isn't any sufficient data to advise a frequency of these examinations (clinical examination, ultrasound and CA-125) in case of treated BOT. CONCLUSION Risk of relapse after surgical treatment of BOT depends on patients' characteristics, type of BOT (histological features) and modalities of initial treatment. Scores and nomogram are useful tools to assess risk of relapse. Follow-up must be performed beyond 5 years and in case of peculiar situations, use of paraclinic evaluations is recommended.

Abstract
In women presenting with an abdominal mass and ascites, the first diagnosis to consider is ovarian cancer. However, clinicians should always consider alternative differentials, namely, peritoneal tuberculosis, especially in the presence of respiratory symptoms and with the increasing prevalence of extrapulmonary tuberculosis. Peritoneal tuberculosis can mimic the clinical presentation of ovarian cancer, and on imaging, it can show similar features of peritoneal carcinomatosis and nodules. Tumor markers can also be elevated in the absence of malignancy. We present the case of a 44-year-old woman with abdominal distension and ascites. Imaging with CT scan, MRI, and PET scan were inconclusive, showing peritoneal nodules. Cytology of ascites was negative. Laparoscopy was done showing Koch bacilli followed by pulmonary sampling showing Mycobacterium tuberculosis. The patient was treated with quadritherapy with resolution of symptoms.

Abstract
BACKGROUND The role of calcineurin/NFAT signaling in ovarian cancer has been unknown. NFAT was significantly overexpressed in ovarian cancer tissues and that overexpression of NFAT was significantly associated with metastasis and poor prognosis on clinical tissue level. To investigate whether NFAT upstream protein, calcineurin (CN), affects the prognosis in various histological subtype of ovarian cancer (OC). METHODS The association between CN and clinical features was analyzed in 50 OC patients treated from 2007 to 2012. CN expression was examined using immunohistochemistry. We observed the association of CN expression with the prognosis in these patients. RESULTS CN expression was significantly increased in later-stage tumor tissue of serous carcinoma compared with those with early-stage. The expression of CN positively correlated with the serum cancer antigen 125 (CA125) level in ovarian clear-cell carcinoma and the serum alpha-fetoprotein (AFP) level in papillary serous cystadenocarcinoma. Particularly, higher CN expression in tumor tissues significantly correlated with reduced overall survival among patients with serous carcinoma. In addition, the serum cancer antigen 72-4 (CA72-4) level, serum carcinoembryonic antigen (CEA) levels, pathological stage, lymph node metastasis, and chemotherapeutic resistance were identified as significant prognostic factors in ovarian clear-cell carcinoma, serous carcinoma, or papillary serous cystadenocarcinoma. CONCLUSIONS CN is upregulated in ovarian cancer tissues with later-stage and that the expression of CN, CA72-4, and CEA was remarkably associated with poor prognosis in unique subtype of ovarian cancer. CN levels may be investigated for use as a prognostic biomarker for risk assessment in unique subtype of OC patients.

Abstract
CA724 is a clinically used serum biomarker used for cancer diagnosis, which includes digestive tract cancers (esophageal, gastric, and colorectal carcinomas), ovarian cancer, and nonsmall cell lung cancer. In general, the serum CA724 level is lower than 6U/mL in healthy controls and significantly higher in cancer patients. It has been further established that serum CA724 level is related to the pathological stage and prognosis of cancers. However, CA724 is not only expressed in tumor tissues but also in normal tissues such as the secretory endometrium and transitional colonic mucosa, which indicates that CA724 is not a unique product of cancer cells. Currently, the serum CA724 levels in patients suffering cancer or nonneoplasm diseases have not been systematically measured and compared. In our study, a total of 38,526 clinical lab test results of serum CA724 levels from healthy controls and patients suffering 34 different types of diseases including cancers and nonneoplasm illnesses during the past 3 years (2015-2018) were collected and analyzed. We found that the mean values of serum CA724 levels were significantly higher in patients suffering gout (23.7U/mL) and gouty arthritis (31.45U/mL) than that of cancer patients (Mann-Whitney test, p<0.0001). The summarized mean and median values of serum CA724 data for healthy controls vs patients suffering 34 different types of diseases indicated that the abnormal serum CA724 levels might be a systemic malfunction indicator rather than a cancer cell-secreted product; the log10p values showed that CA724 is not only a cancer biomarker but also a potential biomarker for patients suffering gout.

Ykl-40 and cancer antigen 72-4 as new and promising diagnostic and prognostic markers for endometrial cancer. Turk J Obstet Gynecol 2019; 15:235-242. [PMID: 30693139 PMCID: PMC6334238 DOI: 10.4274/tjod.77906] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2018] [Accepted: 09/03/2018] [Indexed: 12/14/2022] Open
Abstract
Objective: To determine the predictive role of serum levels of YKL-40 and cancer antigen (CA) 72-4 in the diagnosis of endometrial cancer (EC). Materials and Methods: Forty-one patients with EC and 21 women with uterine polyps were evaluated between January and December 2015 in a prospective study. Results: Age, body mass index, preoperative serum YKL-40 and CA 72-4 levels were significantly higher in the malignant group compared with the control group. Serum YKL-40 levels were significantly higher in patients with superficial myometrial invasion and no lymph node involvement (p=0.042; p=0.004). No relationship between clinicopathologic factors and serum CA 72-4 levels was found. Conclusion: Serum CA 72-4 and YKL-40 levels are increased in women with EC compared with uterine polyps. Preoperative serum YKL-40 levels may be associated with favorable prognostic factors. The determination of YKL-40 before surgery may be helpful in the evaluation of the regional lymph nodes.

J Dig Dis 2018; 19:685-692.

Abstract
OBJECTIVE Over the past decades, carbohydrate antigen 72-4 (CA72-4) was thought to be a tumor marker that was elevated in healthy individuals and patients with malignancies, including gastrointestinal (GI), ovarian, endometrial and lung malignancies. Furthermore, studies found that elevated serum CA72-4 might predict digestive tumors, especially gastric tumors, although there was still neither a sensitive nor specific tumor biomarker for gastric cancer (GC). This study aimed to evaluate the diagnostic accuracy of CA72-4 in predicting malignancies, especially GC. METHODS Altogether 403 patients underwent a CA72-4 test after admission to the Department of Gastroenterology in Changhai Hospital, the Second Military Medical University, from 1 June 2015 to 31 October 2015. Their age and sex, main symptoms, and final diagnoses were summarized. RESULTS The positive predictive value, negative predictive value, positive likelihood ratio and negative likelihood ratio of CA72-4 for diagnosing GC were 31.58%, 79.17%, 1.70, and 0.97, respectively. In the receiver operating characteristic (ROC) curve analysis, the area under the ROC curve for discriminating between patients with GC and those without was 0.62. CONCLUSION Performing a CA72-4 test on its own is of little use for predicting malignances, especially GC, in patients with GI diseases.

Abstract
Gynecological tumors, including endometrial, cervical and ovarian cancer, have increased in incidence over time. The widespread introduction of screening programs and advances in diagnostic imaging methods has lead to a progressive increase in gynecological cancer detection. Accurate diagnosis and proper monitoring of disease remain the primary target for a successful treatment. In the last years, knowledge about cancer biomarkers has considerably increased providing great opportunities for improving cancer detection and treatment. In addition, in the last few years there has been an important development of imaging techniques. Nowadays, a multimodal approach including the evaluation of serum tumor biomarkers combined with imaging techniques, seems to be the best strategy for assessing tumor presence, spread, recurrence, and/or the response to treatment in female cancer patients In this review we provide an overview of the application of biomarkers combined with novel imaging methods and highlight their roles in female cancer diagnosis and follow-up.

Abstract
Blood-based protein biomarkers have recently shown as simpler diagnostic modalities for colorectal cancer, while their association with clinical pathological characteristics is largely unknown. In this study, we not only examined the sensitivity and reliability of single/multiple serum markers for diagnosis, but also assessed their connection with pathological parameters from a total of 279 colorectal cancer patients. Our study shown that glycoprotein carcinoembryonic antigen (CEA) owns the highest sensitivity among single marker in the order of CEA > cancer antigen 72-4 (CA72-4) > cancer antigen 19-9 9 (CA19-9) > ferritin > cancer antigen 125 (CA125), while the most sensitive combined-markers for two to five were: CEA + CA72-4; CEA + CA72-4 + CA125; CEA + CA19-9 + CA72-4 + CA125; and CEA + CA19-9 + CA72-4 + CA125 + ferritin, respectively. We also demonstrated that patients who had positive preoperative serum CEA, CA19-9, or CA72-4 were more likely with lymph node invasion, positive CA125 were prone to have vascular invasion, and positive CEA or CA125 were correlated with perineural invasion. In addition, positive CA19-9, CA72-4, or CA125 was associated with poorly differentiated tumor, while CEA, CA19-9, CA72-4, CA125 levels were positively correlated with pathological tumor-node-metastasis stages. We here conclude that combined serum markers can be used to not only diagnose colorectal cancer, but also appraise the tumor status for guiding treatment, evaluation of curative effect, and prognosis of patients.

Abstract
BACKGROUND There is overlap in imaging features between borderline and benign ovarian tumors. PURPOSE To analyze diagnostic performance of magnetic resonance imaging (MRI) combined with tumor markers for differentiating borderline from benign ovarian tumor. MATERIAL AND METHODS Ninety-nine patient with MRI and surgically confirmed ovarian tumors 5 cm or larger (borderline, n = 37; benign, n = 62) were included. On MRI, tumor size, septal number (0; 1-4; 5 or more), and presence of solid portion such as papillary projection or septal thickening 0.5 cm or larger were investigated. Serum tumor markers (carbohydrate antigen 125 [CA 125] and CA 19-9) were recorded. Multivariate analysis was conducted for assessing whether combined MRI with tumor markers could differentiate borderline from benign tumor. The diagnostic performance was also analyzed. RESULTS Incidence of solid portion was 67.6% (25/37) in borderline and 3.2% (2/62) in benign tumors (P < 0.05). In all patients, without combined analysis of MRI with tumor markers, multivariate analysis revealed solid portion (P < 0.001) and CA 125 (P = 0.039) were significant for predicting borderline tumors. When combined analysis of MRI with CA 125 ((i) the presence of solid portion or (ii) CA 125 > 44.1 U/mL with septal number ≥5 for borderline tumor) is incorporated to multivariate analysis, it was only significant (P = 0.001). The sensitivity, specificity, PPV, NPV, and accuracy of combined analysis of MRI with CA 125 were 89.1%, 91.9%, 86.8%, 93.4, and 90.9%, respectively. CONCLUSION Combined analysis of MRI with CA 125 may allow better differentiation between borderline and benign ovarian tumor compared with MRI alone.

Abstract
Carbohydrate antigen 72-4 (CA72-4) is a human tumor-associated glycoprotein, commonly used as a tumor marker for diagnosing and predicting outcome in gastric and ovarian cancers. However, the relationship between serum CA72-4 levels and prognosis of pancreatic adenocarcinoma has not been fully elucidated. A total of 113 consecutive locally advanced pancreatic adenocarcinoma patients who underwent intensity-modulated radiation therapy (IMRT) with or without chemotherapy were enrolled in this study. Serum CA72-4 levels were analyzed using immunoenzymometric assays. The association between serum CA72-4 levels and prognosis was evaluated. Serum CA72-4 levels was related with lymph node metastasis (P<0.001). The median overall survival time was 14.0 months for patients with serum CA72-4 normal levels and 10.0 months for the elevated levels (P<0.001). Multivariate analysis identified that Serum CA72-4 concentration was a significant prognostic factor (P<0.001). The hazard ratio (HR) of elevated serum CA72-4 levels compared with normal serum CA72-4 levels was 2.34 (95% confidence interval [CI]: 1.46-3.73), after adjusted for gender and age. Based on this finding, Serum CA72-4 is a potential marker to predict lymph node metastasis and prognosis in pancreatic adenocarcinoma.

Abstract
Ovarian masses, a common finding among pre- and post-menopausal women, can be benign or malignant. Ovarian cancer is the leading cause of death from gynecologic malignancy among women living in industrialized countries. According to the current guidelines, measurement of CA125 tumor marker remains the gold standard in the management of ovarian cancer. Recently, HE4 has been proposed as emerging biomarker in the differential diagnosis of adnexal masses and in the early diagnosis of ovarian cancer. Discrimination of benign and malignant ovarian tumors is very important for correct patient referral to institutions specialized in care and management of ovarian cancer. Tumor markers CA125 and HE4 are currently incorporated into the "Risk of Ovarian Malignancy Algorithm" (ROMA) with menopausal status for discerning malignant from benign pelvic masses. The availability of a good biomarker such as HE4, closely associated with the differential and early diagnosis of ovarian cancer, could reduce medical costs related to more expensive diagnostic procedures. Finally, it is important to note that HE4 identifies platinum non-responders thus enabling a switch to second line chemotherapy and improved survival.

Abstract
Borderline ovarian tumours are low malignant potential tumours. They represent 10-15% of all epithelial ovarian malignancies. Patients with this type of tumour are younger at the time of diagnosis than patients with invasive ovarian cancer. Most of them are diagnosed in the early stages and have an excellent prognosis. It has been quite clearly established that the majority of borderline ovarian tumours should be managed with surgery alone. Because a high proportion of women with this malignancy are young and the prognosis is excellent, the preservation of fertility is an important issue in the management of these tumours. In this systemic review of the literature, we have evaluated in-depth oncological safety and reproductive outcomes in women with borderline ovarian tumours treated with fertility-sparing surgery, reviewing the indications, benefits, and disadvantages of each type of conservative surgery, as well as new alternative options to surgery to preserve fertility.

Abstract
OBJECTIVES To assess the preoperative serum levels of CA 125 with its diagnostic role and to evaluate the p53 expression in patients of primary ovarian neoplasms. We also wished to judge their relationship with other parameters like clinical staging and histopathologic tumor type. MATERIALS AND METHODS The present study was conducted on 86 patients during the study period of 2.5 years. Preoperative CA 125 levels were evaluated by an automated immunoassay analyzer. p53 expression was judged immunohistochemically with pre-diluted monoclonal antibody. An objective scoring was done depending on distinct nuclear immunopositivity. RESULTS Median value of preoperative CA 125 levels was 32 U/mL in benign surface epithelial-stromal tumors (BSEST), 53 U/mL in borderline surface epithelial-stromal tumors (BOT), 346 U/mL in malignant surface epithelial-stromal tumors (MSEST) and 560 U/mL in serous adenocarcinomas (SAC). Most of ovarian tumors were in the FIGO stage I (64 cases, 74.4%), but higher stages (II, III, IV) were observed mostly in MSESTs. SACs displayed the maximum p53 expression. Considering the cut-off value of more than 35 U/mL in CA 125 levels, the sensitivity to diagnose MSESTs was 94.7%. Preoperative CA 125 levels strongly and positively correlated with FIGO staging and p53 expression. Similarly p53 expression strongly and positively correlated with FIGO staging and histopathological categories. CONCLUSION Higher values of preoperative CA 125 levels and higher expression p53 are associated with MSESTs and BOTs especially of serous type. They strongly correlate with each other and with tumor stage. But there is no serum CA 125 concentration that can clearly differentiate benign and malignant ovarian masses.

Abstract
OBJECTIVES CA 72-4 is not approved as a tumor marker but has been used as an adjunct marker in gynecological practice. The study aims to evaluate the menstrual cycle variability of CA 72-4 in a population of healthy women. DESIGN AND METHODS Forty apparently healthy regularly menstruating subjects were included in the cross-sectional study designed in the University Obstetrics and Gynecology outpatient clinic. Venous blood samples from each participant were collected twice: first at the follicular phase (2nd-5th days of the menstrual cycle) for FSH, estradiol, CA 125, CA 72-4 and the other at the luteal phase (21st-24th days of the menstrual cycle) for progesterone, CA 125 and CA 72-4 levels. RESULTS CA 72-4 values were similar in follicular and luteal phase of the menstrual cycle in apparently healthy regularly menstruating subjects (1.15U/mL (0.2-5.4) vs 1.15 U/mL (0.56-6.3); p=0.326 respectively). Ovulatory or smoking status did not have an effect on CA 72-4 values (p>0.05). CONCLUSION This first clinical study about the menstrual cycle variability of CA 72-4 revealed that the menstrual cycle does not have a significant impact on CA 72-4 values and that it can be measured at any time during the menstrual period.

Abstract
Background. Surgical excision of ovarian endometriomas in patients desiring pregnancy has recently been criticized because of the risk of damage to healthy ovarian tissue and consequent reduction of ovarian reserve. A correct diagnosis in cases not scheduled for surgery is therefore mandatory in order to avoid unexpected ovarian cancer misdiagnosis. Endometriosis is often associated with high levels of CA125. This marker is therefore not useful for discriminating ovarian endometrioma from ovarian malignancy. The aim of this study was to establish if the serum marker CA72-4 could be helpful in the differential diagnosis between ovarian endometriosis and epithelial ovarian cancer. Methods. Serums CA125 and CA72-4 were measured in 72 patients with ovarian endometriomas and 55 patients with ovarian cancer. Results. High CA125 concentrations were observed in patients with ovarian endometriosis and in those with ovarian cancer. A marked difference in CA72-4 values was observed between women with ovarian cancer (71.0%) and patients with endometriosis (13.8%) (P < 0.0001). Conclusions. This study suggests that CA72-4 determination can be useful to confirm the benign nature of ovarian endometriomas in women with high CA125 levels.

Abstract
Background Endometriosis is frequently associated with high levels of CA125. This marker is therefore not useful for discriminating ovarian endometrioma from ovarian malignancy. The aim of this study was to establish a panel of complementary biomarkers that could be helpful in the differential diagnosis between ovarian endometriosis or other ovarian benign masses and ovarian cancer. Methods Blood samples from 50 healthy women, 17 patients with benign ovarian tumors, 57 patients with ovarian endometrioma and 39 patients with ovarian cancer were analyzed and serum values were measured for the following biomarkers: CA125, HE4 and CA72-4. Results Serum CA125 concentration was elevated in both patients with ovarian endometriosis and ovarian cancer but not in patients with other benign ovarian masses. HE4 was never increased in patients with endometriosis or benign masses whereas it was significantly higher in all patients with ovarian cancer (p < 0.05). A marked difference in CA72-4 values was observed between women with ovarian cancer (67%) and those with endometriosis (p < 0.05). Conclusions The results of the study suggest that HE4 and CA72-4 determination is the best approach to confirm the benign nature of ovarian endometrioma in women with high CA125 levels.

Abstract
BACKGROUND Borderline ovarian tumors (BOTs) are a subset of epithelial ovarian tumors with low malignant potential but significant risk of relapse (10% to 30%). Unfortunately, surgical prognostic factors for BOT relapse have not been clearly identified, probably due to the use of heterogeneous surgical definitions and limited follow-up. The aim of this study was to assess potential relapse risk factors using standard surgical definitions and long follow-up. METHODS All patients diagnosed with BOT for a period of more than 10 years in a single institution were included in the analysis. Complete surgical staging was defined as the set of procedures that follow standard guidelines for staging surgery (except lymphadenectomy), performed either with one or two interventions. Fertility-sparing surgeries that preserved one ovary and the uterus but included all the remaining procedures were classified as complete staging. The relationship between potential risk factors and time to BOT relapse was assessed by log-rank tests corrected for multiple comparisons and Cox regression. RESULTS Forty-six patients with a median follow-up of 5.4 years were included, of whom 91.3% had been diagnosed as FIGO stage I disease and 45.7% had received complete staging surgery. Five relapses were detected (10.9%), all of them in women who had been diagnosed with stage I disease and had received incomplete staging surgery. Log-rank tests confirmed the association between incomplete staging surgery and shorter time to BOT relapse. CONCLUSIONS Complete staging surgery should be considered a cornerstone of BOT treatment in order to minimize the risk of relapse.

Abstract
Borderline ovarian tumors (BOTs) represent approximately 10% of ovarian neoplasms and are a heterogeneous group of tumors with variable biological behaviour. The majority present with disease confined to the ovary and have an excellent prognosis after surgical removal. A small proportion subsequently has recurrent disease or progression to invasive cancer. Tumor recurrence can occur up to 20 years after surgical resection. There are no robust clinical, histological or molecular markers that distinguish high risk cases and no satisfactory treatment for patients with progressive disease. This results in great variability in management in different centres. We conducted a national survey on the management of borderline ovarian tumors in cancer centres representing different regions in the United Kingdom. In this article we review the literature for the current concepts in diagnosis, treatment and follow up of BOTs and we report the results of the survey of current practice in the United Kingdom. On that basis we provide recommendations for the management of patients with BOTs.

Abstract
The aim of this study was to investigate the role of biomarkers CA125, HE4, and CA72.4 at diagnosis and throughout the follow-up in patients with epithelial ovarian cancer (EOC). Thirty-nine patients with EOC were deemed eligible, and 20 were followed up. CA125, HE4, and CA72.4 serum levels were determined for all patients at initial diagnosis of EOC. Among these patients, the number of cases with an elevated level of each individual marker was CA125 77 %, HE4 85 %, and CA72.4 72 %. A statistically significant difference was observed between the level of HE4 when compared to CA72.4 (p < 0.02). In the follow-up phase, we observed tumor marker levels fluctuating according to response to chemotherapy. When combining two out of the three biomarkers together, we observed increased values of CA125 and CA72.4 in 55 % of the patients, increased values of CA125 and HE4 in 65 % of the patients, and finally increased HE4 and CA72.4 in 75 % of the patients. A statistically significant difference was observed when combining HE4 and CA72.4, but not CA125 and CA 72.4 (p < 0.002). In conclusion, our study demonstrates that the association of three biomarkers CA125, HE4, and CA72.4 provides a valuable contribution in the follow-up of EOC patients.

Prognostic value of elevated preoperative serum CA125 in ovarian tumors of low malignant potential: a multinational collaborative study (ANZGOG0801). Gynecol Oncol 2012; 126:36-40. [PMID: 22370601 DOI: 10.1016/j.ygyno.2012.02.031] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2011] [Revised: 02/20/2012] [Accepted: 02/20/2012] [Indexed: 10/28/2022]
Abstract
OBJECTIVE Previous studies on prognostic factors in ovarian tumors of low malignant potential (LMP) were too small for robust conclusions. We examined the prognostic impact of preoperative serum CA125 ≥ 50 U/ml levels in patients diagnosed with ovarian LMP tumors in a large multinational cohort. METHODS This retrospective study included 940 patients with ovarian LMP tumors diagnosed between 1985 and 2008 at six gynecologic cancer centers. Patients either had radical treatment (bilateral salpingo-oophorectomy with or without hysterectomy) or conservative, fertility-sparing treatment. Multivariate Cox proportional hazard models were used to determine independent prognostic factors for disease-free (DFS) and overall survival (OS). Based on receiver operating characteristic curve (ROC), a preoperative serum CA125 level ≥ 50 U/ml was considered "elevated". RESULTS CA125 was more often elevated in serous than in mucinous tumors and in advanced FIGO stages (2 to 4) compared to stage 1. DFS at 5 years was 89% and 95% in patients with elevated and normal CA125 levels (p<0.05). Similarly, the 5-year OS was 90% among patients with elevated CA125 compared to 95% among patients with normal levels (p<0.05). For both DFS and OS elevated CA125 levels and advanced stages of the disease were independent prognostic factors. Analysis of subgroups revealed that CA125 was only prognostic in serous LMP tumors. CONCLUSIONS In the context of serous ovarian LMP tumors, elevated preoperative serum CA125 represents a biomarker independently associated with impaired disease-free and overall survival. CA125 is available in most centers and could inform surgeons about the risk of treatment failure.

Abstract
BACKGROUND Cancer antigen 125 (CA125) is the best known single tumor marker for ovarian cancer (OC). We investigated whether the additional information of the human epididymis protein 4 (HE4) improves diagnostic accuracy. METHODS We retrospectively analyzed preoperative sera of 109 healthy women, 285 patients with benign ovarian masses (cystadenoma: n=78, leimyoma: n=66, endometriosis: n=52, functional ovarian cysts: n=79, other: n=10), 16 low malignant potential (LMP) ovarian tumors and 125 OC (stage I: 22, II: 15, III: 78, IV: 10). CA125 was analyzed using the ARCHITECT system, HE4 using the ARCHITECT(a) system and EIA(e) technology additionally. RESULTS The lowest concentrations of CA125 and HE4 were observed in healthy individuals, followed by patients with benign adnexal masses and patients with LMP tumors and OC. The area under the curve (AUC) for the differential diagnosis of adnexal masses of CA125 alone was not significantly different to HE4 alone in premenopausal (CA125: 86.7, HE4(a): 82.6, HE4(e): 81.6% p>0.05) but significantly different in postmenopausal [CA125: 93.4 vs. HE4(a): 88.3 p=0.023 and vs. HE4(e): 87.8% p=0.012] patients. For stage I OC, HE4 as a single marker was superior to CA125, which was the best single marker in stage II-IV. The combination of CA125 and HE4 using risk of malignancy algorithm (ROMA) gained the highest sensitivity at 95% specificity for the differential diagnosis of adnexal masses [CA125: 70.9, HE4(a): 67.4, HE4(e): 66.0, ROMA(a): 76.6 and ROMA(e): 74.5%], especially in stage I OC [CA125: 27.3, HE4(a): 40.9, HE4(e): 40.9, ROMA(a): 45.5 and ROMA(e): 45.5%]. CONCLUSIONS CA125 is still the best single marker in the diagnosis of OC. HE4 alone and even more the combined analysis of CA125 and HE4 using ROMA improve the diagnostic accuracy of adnexal masses, especially in early OC.

Abstract
BACKGROUND The CA-125 tumor marker has limitations when used to distinguish between benign and malignant ovarian masses. We therefore establish likelihood curves of six subgroups of ovarian pathology based on CA-125 and menopausal status. METHODS This cross-sectional study conducted by the International Ovarian Tumor Analysis group involved 3,511 patients presenting with a persistent adnexal mass that underwent surgical intervention. CA-125 distributions for six tumor subgroups (endometriomas and abscesses, other benign tumors, borderline tumors, stage I invasive cancers, stage II-IV invasive cancers, and metastatic tumors) were estimated using kernel density estimation with stratification for menopausal status. Likelihood curves for the tumor subgroups were derived from the distributions. RESULTS Endometriomas and abscesses were the only benign pathologies with median CA-125 levels above 20 U/mL (43 and 45, respectively). Borderline and invasive stage I tumors had relatively low median CA-125 levels (29 and 81 U/mL, respectively). The CA-125 distributions of stage II-IV invasive cancers and benign tumors other than endometriomas or abscesses were well separated; the distributions of the other subgroups overlapped substantially. This held for premenopausal and postmenopausal patients. Likelihood curves and reference tables comprehensibly show how subgroup likelihoods change with CA-125 and menopausal status. CONCLUSIONS AND IMPACT Our results confirm the limited clinical value of CA-125 for preoperative discrimination between benign and malignant ovarian pathology. We have shown that CA-125 may be used in a different way. By using likelihood reference tables, we believe clinicians will be better able to interpret preoperative serum CA-125 results in patients with adnexal masses.

Abstract
BACKGROUND Two commercial immunoassays for HE4 have been compared and the diagnostic accuracy of HE4, CA 125 and the combinatory ROMA algorithm for epithelial ovarian cancer (EOC) has been evaluated. METHODS HE4 and CA125 were measured on sera obtained from 259 women (73 healthy, 90 with benign ovarian or adnexal diseases, 96 with EOC). The ARCHITECT CMIA HE4 assay was compared with the Fujirebio EIA HE4, and the risk for EOC by the combinatory ROMA algorithm (HE4+CA 125) was assessed with both HE4 assays. RESULTS The CMIA HE4 assay showed a good linearity (r>0.9998) and precision (interassay and total CVs <4%). The correlation with EIA HE4 was linear (r=0.994), with an average bias of 0.4%. By ROC curve analysis, the sensitivity for EOC at a fixed specificity of 90%, 95% and 99% was 89.6%, 84.4% and 79.2% by CMIA HE4, 84.4%, 83.3% and 79.2% by EIA HE4, 86.5%, 76.0% and 59.4% by CMIA CA125. The accuracy of the ROMA algorithm determined by CMIA or EIA HE4 was very similar (AUC 87.1% vs. 87.6%; p=n.s.) and greater in menopause. CONCLUSIONS The two HE4 assays showed a good correlation and similar clinical value, with a greater precision for CMIA. HE4 was more specific and accurate than CA125, supporting its use in addition to clinical and imaging criteria for the discrimination of benign from malignant ovarian lesions. The ROMA algorithm showed a good accuracy for discriminating women at high risk for EOC.

Abstract
The endometrial fluid is a noninvasive sample which contains numerous secreted proteins representative of endometrial function and reflects the state of the endometrium. In this study, we describe, for the first time, a comprehensive catalogue of proteins of the endometrial fluid during the secretory phase of the menstrual cycle. To achieve this objective, three different but complementary strategies were used: First, in-solution digestion followed by reverse phase high-performance liquid chromatography coupled with tandem mass spectrometry (HPLC-MS/MS); second, protein separation by denaturing one-dimensional electrophoresis (SDS-PAGE) followed by HPLC-MS/MS analysis. Finally, two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) followed by MALDI-TOF/TOF analysis. The combination of the three strategies led to the successful identification of 803 different proteins in the International Protein Index (IPI) human database (v3.48). An extensive description of the endometrial fluid proteome will help provide the basis for a better understanding of a number of diseases and processes, including endometriosis, endometrial cancer and embryo implantation. We believe that the thorough catalogue of proteins presented here can serve as a valuable reference for the study of embryo implantation and for future biomarker discovery involved in pathologic alterations of endometrial function.
