Abstract
Cancer antigen 125 (CA125) is pivotal as a tumor marker in early ovarian cancer prevention and diagnosis. In this work, we introduced an ultrasensitive label-free electrochemical immunosensor tailored for CA125 detection, leveraging nanogold-functionalized copper-cobalt oxide nanosheets (CuCo-ONSs@AuNPs) as nanocomposites. For the inaugural application, copper-cobalt oxide nanosheets delivered the requisite DPV electrochemical response for the immunosensors. Their large specific surface area and commendable electrical conductivity amplify electron transfer and enable significant gold nanoparticle loading. Concurrently, AuNPs offer a plethora of active sites, facilitating easy immobilization of biomolecules via the bond between amino groups and AuNPs. We employed scanning electron microscopy, transmission electron microscopy, and x-ray photoelectron spectroscopy to characterize the nanomaterials' surface morphology and elemental composition. The electrochemical sensor response signals were ascertained using differential pulse voltammetry. Under optimal conditions, the immunosensor exhibited a linear detection range from 1×10-7 U/mL to 1×10-3 U/mL and a detection limit of 3.9×10-8 U/mL (S/N=3). The proposed label-free electrochemical immunosensor furnishes a straightforward, dependable, and sensitive approach for CA125 quantification and stands as a promising method for clinical detection of other tumor markers.

Abstract
BACKGROUND CA125 is a widely used serum marker for epithelial ovarian cancer which levels may also rise in benign conditions involving peritoneal irritation. We aimed to determine if serum CA125 levels can predict disease severity in patients presenting with acute diverticulitis. METHODS We conducted a single-center prospective observational study, analyzing CA125 serum levels in patients who presented to the emergency department with computerized tomography-proven acute left-sided colonic diverticulitis. Univariate, multivariate, and receiver operating characteristic (ROC) analyses were used to correlate CA125 serum levels at time of initial presentation with the primary outcome (complicated diverticulitis) and secondary clinical outcomes (need for urgent intervention, length of hospital stay (LOS) and readmission rates). RESULTS One hundred and fifty-one patients were enrolled between January 2018 and July 2020 (66.9% females, median age 61 years). Twenty-five patients (16.5%) presented with complicated diverticulitis. CA125 levels were significantly higher among patients with complicated (median: 16 (7-159) u/ml) vs. uncomplicated (8 (3-39) u/ml) diverticulitis (p < 0.001) and also correlated with the Hinchey severity class (p < 0.001). Higher CA125 levels upon admission were associated with a longer LOS and a greater chance to undergo invasive procedure during the hospitalization. In patients with a measurable intra-abdominal abscess (n = 24), CA125 levels were correlated with the size of the abscess (Spearman's r = 0.46, p = 0.02). On ROC analysis to predict complicated diverticulitis, the area under the curve (AUC) for CA125 (AUC = 0.82) was bigger than for the leukocyte count (AUC = 0.53), body temperature (AUC = 0.59), and neutrophil-lymphocyte ratio (AUC = 0.70) - all p values < 0.05. On multivariate analysis of factors available at presentation, CA125 was found to be the only independent predictor of complicated diverticulitis (OR 1.12 (95% CI 1.06-1.19), p < 0.001). CONCLUSIONS The results from this feasibility study suggest that CA125 may accurately discriminate between simple and complicated diverticulitis, meriting further prospective investigation.

Abstract
A simple label-free electrochemical immunosensor for ovarian cancer (OC) detection was developed using a hierarchical microporous carbon material fabricated from waste coffee grounds (WCG). The analysis method exploited near-field communication (NFC) and a smartphone-based potentiostat. Waste coffee grounds were pyrolyzed with potassium hydroxide and used to modify a screen-printed electrode. The modified screen-printed electrode was decorated with gold nanoparticles (AuNPs) to capture a specific antibody. The modification and immobilization processes were characterized by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The sensor had an effective dynamic range of 0.5 to 50.0 U mL-1 of cancer antigen 125 (CA125) tumor marker with a correlation coefficient of 0.9995. The limit of detection (LOD) was 0.4 U mL-1. A comparison of the results obtained from human serum analysis with the proposed immunosensor and the results obtained from the clinical method confirmed the accuracy and precision of the proposed immunosensor.

Abstract
BACKGROUND The mortality rate of ovarian cancer ranks first among three common gynecological malignant tumors due to insidious onset and lack of effective early diagnosis methods. Borderline epithelial ovarian tumor (BEOT) is a type of low malignant potential tumor that is typically associated with better outcomes than ovarian cancer. However, BEOTs are easily confused with benign and malignant epithelial ovarian tumors (EOTs) due to similar clinical symptoms and lack of specific tumor biomarkers and imaging examinations. Notably, a small subset of BEOTs will transform into low-grade serous ovarian carcinoma with a poor prognosis. Therefore, searching for potential biomarkers that can be easily obtained and accurately identify malignant epithelial ovarian tumors (MEOTs) as well as BEOTs is essential for the clinician. Cancer antigen 125 (CA125) is a commonly used biomarker for the diagnosis of EOTs in the preoperative scenario but has low sensitivity and specificity. Nowadays, inflammatory biomarkers including inflammatory cell counts and derived ratios such as neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR) have been proved to be associated with tumor progression and poor prognosis, and were considered to be the most economically potential surrogate biomarkers for various malignancies. The purpose of this study was to find appropriate combinations of inflammatory and tumor biomarkers to improve the diagnostic efficiency of EOTs, especially the BEOTs. RESULTS CA125, NLR and PLR increased steadily among benign, borderline and malignant EOTs and tended to be higher in advanced (stage III-IV) and lymph node metastasis MEOT groups than in early stage (stage I-II) and non-lymph node metastasis MEOT groups. CA125, NLR and PLR could be used separately in the differentiation of EOTs but could not take into account both sensitivity and specificity. The combined use of CA125, NLR and PLR was evaluated to be more efficient, especially in the identification of BEOTs, with both high sensitivity and high specificity. CONCLUSIONS The levels of CA125, NLR and PLR were closely related to the nature of EOTs and malignant progression of MEOTs. The combination of CA125, NLR and PLR was more accurate in identifying the nature of EOTs than either alone or double combination, especially for BEOTs.

Abstract
Ovarian cancer is the most lethal gynecologic malignancy, mostly diagnosed in the advanced stage with multiple sites of metastases. Routes of spread are direct through exfoliation, lymphatic channels, and less commonly hematogenous spread. Skin metastasis in ovarian malignancy is a rare occurence, its incidence range from 1.9% to 5.1% and the most common sites are the abdominal wall and chest wall. The incidence of metastasis to breast and/or axillary lymph nodes is very rare, ranging from 0.03% to 0.6%. We report the case of a 60-year-old female with stage IV B undifferentiated ovarian carcinoma with multiple cutaneous metastases involving the skin over the left breast, scalp, and mediastinal lymph nodes, which are rare sites of metastases. The incidence of cutaneous metastasis in ovarian cancer is 1.9%-5.1% and the overall survival after diagnosis ranges from 2 to 65 months.

Abstract
INTRODUCTION Light-chain (AL) cardiorenal amyloidosis has been characterized as type 5 cardiorenal syndrome with fluid overload and poor prognosis. Cancer antigen 125 (CA125) has the potential for its use in evaluating fluid load and prognosis for heart failure. However, less details for CA125 in AL cardiorenal amyloidosis have been reported. METHODS Sixty patients diagnosed with AL cardiorenal amyloidosis were enrolled in this retrospective study. Patients were divided into two groups according to the cutoff point of CA125 level (35 U/mL). Logistic regression was used to screen variables associated with CA125. Cox regression analyses were utilized to verify the prognostic potential of CA125. RESULTS The mean age was 61 ± 8 years, and 68% of the participants were male. Compared to patients with normal CA125 levels (≤35 U/mL), patients with high levels of CA125 (>35 U/mL) had a higher proportion of New York Heart Association class >II, pericardial effusion, and edema, as well as a lower level of albumin and left ventricular longitudinal strain (LVLS). Logistic regression showed age, albumin, and LVLS to be independently associated with CA125. Seventeen (28%) patients died during the follow-up. Multivariate model including CA125, estimated glomerular filtration rate, E/e', and left ventricular ejection fraction showed acceptable prognostic potential (C-index = 0.829, 95% CI: 0.749-0.909). CA125 remained an independent prognostic factor (HR = 1.018, 95% CI: 1.005-1.031, p = 0.008, per 10 U/mL increase) after adjusting for the remaining three variates and provided a significant incremental effect to the risk determined from them (C-index 0.829 vs. 0.784, p = 0.037). CONCLUSION Serum CA125 level was associated with long-term prognosis of AL cardiorenal amyloidosis.

Abstract
BACKGROUND MUC16, encoding cancer antigen 125, is a frequently mutated gene in gastric cancer. In addition, MUC16 mutations seem to result in a better prognosis in gastric cancer. However, the mechanisms that lead to a better prognosis by MUC16 mutations have not yet been clarified.
AIM To delve deeper into the underlying mechanisms that explain why MUC16 mutations signal a better prognosis in gastric cancer.
METHODS We used multi-omics data, including mRNA, simple nucleotide variation, copy number variation and methylation data from The Cancer Genome Atlas, to explore the relationship between MUC16 mutations and prognosis. Cox regression and random survival forest algorithms were applied to search for hub genes. Gene set enrichment analysis was used to elucidate the molecular mechanisms. Single-sample gene set enrichment analysis and “EpiDISH” were used to assess immune cells infiltration, and “ESTIMATE” for analysis of the tumor microenvironment.
RESULTS Our study found that compared to the wild-type group, the mutation group had a better prognosis. Additional analysis indicated that the MUC16 mutations appear to activate the DNA repair and p53 pathways to act as an anti-tumor agent. We also identified a key gene, NPY1R (neuropeptide Y receptor Y1), which was significantly more highly expressed in the MUC16 mutations group than in the MUC16 wild-type group. The high expression of NPY1R predicted a poorer prognosis, which was also confirmed in a separate Gene Expression Omnibus cohort. Further susceptibility analysis revealed that NPY1R might be a potential drug target for gastric cancer. Furthermore, in the analysis of the tumor microenvironment, we found that immune cells in the mutation group exhibited higher anti-tumor effects. In addition, the tumor mutation burden and cancer stem cells index were also higher in the mutation group than in the wild-type group.
CONCLUSION We speculated that the MUC16 mutations might activate the p53 pathway and DNA repair pathway: alternatively, the tumor microenvironment may be involved.

Abstract
BACKGROUND In rare instances, primary liver cancer can be associated with intraocular metastasis (IOM).
AIM To investigate the correlation between a diverse range of clinical characteristics and IOM in diabetic patients with primary liver cancer, and to determine potential risk factors in predicting IOM.
METHODS We recruited a total of 722 diabetic patients with primary liver cancer. The differences between the IOM and non-intraocular metastasis (NIOM) groups in these patients were assessed using the chi-squared test and Student’s t-test. Binary logistic regression analysis was subsequently used to determine risk factors. Finally, the diagnostic value of IOM in this cohort with primary liver cancer was analyzed by receiver operating characteristic (ROC) curve analysis.
RESULTS In all, 13 patients had IOM. There were no remarkable intergroup differences with respect to age, sex, histopathological sub-types, or blood biochemical parameters. However, the IOM group had significantly higher alpha-fetoprotein (AFP) and cancer antigen 125 (CA125) values than the NIOM group. Binary logistic regression identified AFP and CA125 to be significant risk factors for IOM in diabetic patients with primary liver cancer. ROC curve analysis showed that the area under the curve values for AFP and CA125 were 0.727 and 0.796, with the cut-off values of 994.20 ng/mL and 120.23 U/mL, respectively. The sensitivity and specificity for AFP were 92.3% and 59.9%, while those for CA125 were 84.6% and 70.1%, respectively.
CONCLUSION Elevated AFP and CA125 represent significant risk factors for IOM in diabetic patients with primary liver cancer.

Abstract
Cancer antigen 125 (CA - 125) is an important biomarker for the diagnosis of ovarian cancer. In this paper, oligonucleotide 5'-GACAGGCCCGAAGGAATAGATAATACGACTCACTATAGGGAGACAAGAATAAACGCTCAA-3' (oligo 1) contains an aptamer of CA - 125, and was designed partly complementary to oligonucleotide 5'-CTCTCTCTCCACCTTCTTCTTTGAGCGTTTATTCTTGTCT-3' (oligo 2). Oligo 1 · oligo 2 was extended with the Klenow fragment (exo-) polymerase for further polymerase chain reaction (PCR) processes in the presence of two primers: deoxyribose nucleoside triphosphate and Taq polymerase. Single-stranded DNA was produced at two sides of the PCR product by introducing a C18 spacer into the two primers, which could hybridize with AuNPs-DNA probes, investigated by dynamic light scattering and fluorescence. The addition of CA - 125 can interrupt the hybridization between oligo 1 and oligo 2, causing the average diameter of AuNPs-DNA probes to decrease with the increase of CA-125 within the range of 5 fg mL-1 - 50 ng mL-1. The linear regression equation of this relationship was D = 430.48-49.60 log10C, with a detection limit of 1.1 fg mL-1. Fluorescein molecules were modified at the end of the forward primer. The fluorescence intensity of the PCR product can be measured simultaneously, with the fluorescence intensity increasing linearly with the logarithm of CA-125 concentration within a linear range from 10 fg mL-1 to 50 ng mL-1, with a detection limit of 1.5 fg mL-1.

Abstract
BACKGROUND Preoperative evaluations aiming to assess high-risk features in clinical stage 1 endometrial cancer patients are crucial to refer these patients to gynecologic oncologists. Cancer antigen 125 (CA125) and human epididymis protein 4 (HE4) have been reported in endometrial cancer patients with poor prognostic factors.
AIM To evaluate the association between preoperative levels of CA125 and HE4 and high-risk features and establish optimal cut-off values in clinical stage 1 endometrial cancer.
METHODS A retrospective study was conducted in clinical stage 1 endometrial cancer patients who underwent primary surgery between January 2013 and December 2018. A total of 128 patients had preoperative serum CA125 and HE4 measurements. High-risk features included grade 3 tumors, large tumor sizes (more than 2 cm), deep myometrial invasion (more than 50%), lymphovascular space invasion (LVSI), cervical involvement, extrauterine involvement and node metastasis. Receiver operating characteristic (ROC) curves were generated to analyze the optimal cut-off values.
RESULTS The mean age of the patients was 57.4 years, and 69.5% of them were postmenopausal. Most patients presented with stage I disease (67.2%) and had the endometrioid subtype (97.7%). The median CA125 and HE4 levels in all patients were 22.1 U/mL and 104.7 pmol/L, respectively. CA125 and HE4 levels were significantly elevated in those with large tumor sizes, deep myometrial invasion, LVSI, extrauterine metastasis, and advanced stage, but node metastasis was associated with elevated CA125 only. According to the ROC curve, both serum markers had statistical significance for the prediction of high-risk features only in postmenopausal patients, with an optimal cut-off value of 20 U/mL for CA125 [area under the concentration-time curve (AUC) = 0.72, P = 0.002] and 113 pmol/L for HE4 (AUC = 0.70, P = 0.006). The combination of both serum markers had 80% sensitivity and 64.4% positive predictive value. Significantly worse 5-year disease-free survival was observed in patients with high levels of CA125 and HE4 (78.4% and 100%, respectively; P = 0.01).
CONCLUSION Preoperative CA125 levels greater than 20 U/mL or HE4 levels greater than 113 pmol/L are associated with an increased risk of having high-risk features and present as prognostic factors in clinical stage 1 postmenopausal endometrial cancer patients. This information is helpful for general gynecologists to refer high-risk patients to gynecologic oncologists to perform complete surgical staging.

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
In the current study, we report on the design and development of a novel electrochemical immunosensor for the detection of cancer antigen 125 (CA125) oncomarker. Polyamidoamine/gold nanoparticles (PAMAM/AuNPs) were used to increase the conductivity and enhance the number of antibodies (Abs) immobilized on the electrode surface. Three-dimensional reduced graphene oxide-multiwall carbon nanotubes (3DrGO-MWCNTs) were used to modify the glassy carbon electrode to improve the electrode conductivity and specific surface area. Ab and toluidine blue attached to O-succinyl-chitosan-magnetic nanoparticles (Suc-CS@MNPs) as a tracer. The poor solubility of chitosan (CS) was improved by succinic anhydride using a novel modification method. Under optimum condition, the developed immunosensor exhibited a wide linear range (0.0005-75 U/mL) and an excellent limit of detection around 6 μU/mL. The reliability of the engineered immunosensor in detecting CA125 was verified by standard addition recovery method, which was further compared to enzyme-linked immunosorbent assay (ELISA). The proposed immunosensor exhibited excellent stability, high selectivity and sensitivity, and good reproducibility. Based on the great performance of the engineered immunosensor, it is proposed as a robust and reliable diagnostic tool for the detection of CA125 in the clinic.

Abstract
OBJECTIVE To assess the utility of hematologic, inflammatory, and immunologic biomarkers for differentiating between ovarian cancer and endometriosis. METHODS Data were retrospectively reviewed from women diagnosed with ovarian cancer and endometriosis after ovarian cyst surgery in Zhejiang, China, 2014-2016. Serologic and hematologic biomarkers, including white blood cell count, lymphocyte count, neutrophil count, red blood cell count, hemoglobin, platelets, and D-dimer, albumin, globulin, cancer antigen 125 (CA125) and CA199 serum levels recorded pre-operatively were assessed by ROC curve and logistic regression analysis. RESULTS Overall, 49 women were diagnosed with ovarian cancer and 192 with endometriosis. For predicting ovarian cancer, the area under the curve (AUC) was 0.96 (95% confidence interval [CI], 0.94-0.99); sensitivity, 93.2%; specificity, 87.5%) for log(D-dimer), 0.95 (95% CI, 0.91-0.98; sensitivity, 81.3%; specificity, 96.3%) for log(CA125), and 0.92 (95% CI, 0.86-0.98; sensitivity, 92.6%; specificity, 79.2%) for neutrophil-to-lymphocyte ratio (NLR). The AUC for the combination of D-dimer, NLR, and CA125 was 0.96 (95% CI, 0.94-0.99; sensitivity, 91.6%; specificity, 89.6%). CONCLUSION Serum D-dimer, NLR, and CA125 were found to be potential diagnostic factors for ovarian cancer. Combined measurement of D-dimer, NLR, and CA125 might offer a convenient screening method.

Abstract
A novel, simple, sensitive, and precise spectrofluorometric assay of cancer antigen [CA 125] is described. This modality is based on monitoring the quenching of the luminescence intensity at 790 nm of the phthalocyanine fluorophore, in a nanocomposite comprising the fluorophore and cationic polystyrene, which results from interaction with CA 125. The remarkable quenching of the luminescence intensity of the Ni-phthalocyanine complex doped in PS matrix by various concentrations of CA 125 was successfully utilized as an optical sensor for the determination of CA 125 in different serum samples of ovarian disease. The performance of the designed biosensor is determined through monitoring the quenching of the luminescence intensity at 790 nm by cancer antigen 125 after excitation at 685 nm, pH 7.3 in water. The calibration plot was achieved over the concentration range 1.0 × 10-2 - 127 U mL-1 CA-125 with a correlation coefficient of 0.99 and detection limit of 1.0 × 10-4 U mL-1. The mechanism of the interaction between the nano thin film nickel(II)phthalocyanine and CA-125 was discussed. A significant correlation between the proposed method for the assessment of CA 125 and the standard method was applied to patients and controls.

Abstract
Background To investigate diffusion-weighted magnetic imaging (DWI) and diffusion kurtosis magnetic imaging (DKI) for the early detection of the response to docetaxel (DTX) chemotherapy in rat epithelial ovarian cancer (EOC). Methods 7,12-Dimethylbenz[A]anthracene was applied to induce orthotopic EOC in Sprague–Dawley rats. Rats with EOC were treated with DTX on day 0 (treatment group) or were left untreated (control group). DWI and DKI were performed on days 0, 3, 7, 14 and 21 after treatment. On day 21, the tumors were categorized into the sensitive and insensitive groups according to the size change. The cutoff values of the DWI and DKI parameters for the early response were determined. The experiment was repeated, and the treatment group was divided into the sensitive and insensitive groups according to the initially obtained cutoff values. The DWI and DKI parameters were correlated with tumor size, proliferation, apoptosis and tumor necrosis. Results In the sensitive vs. insensitive or control group, significant differences were found in the Δ% of the DWI and DKI parameters (ADC, D and K) from day 3 and in tumor size from day 14. Early on day 7, the Δ% of K had an AUC of 1 and sensitivity and specificity values of 100% and 100%, respectively, to detect the response to DTX using a cutoff value of 19.03% reduction in K. From day 7, significant differences were found in the Δ% of Ki-67 and CA125 in the sensitive vs. control group and from day 14 in the sensitive vs. insensitive group. From day 14, there were significant differences in the Δ% of Bcl-2, apoptosis and tumor necrosis in the sensitive vs. control or insensitive group. The Δ% values of ADC and D were negatively correlated with the Δ% values of tumor size, Ki-67, CA125 and Bcl-2 and were positively correlated with the Δ% values of apoptosis and tumor necrosis. The Δ% of K was positively correlated with the Δ% values of tumor size, Ki-67, CA125 and Bcl-2 and was negatively correlated with the Δ% values of apoptosis and tumor necrosis. Conclusions DWI and DKI parameters, especially K, are superior for imaging tumor size for the early detection of the response to DTX chemotherapy in induced rat EOC.

Abstract
Background Cancer antigen (CA) 125 (CA-125) is used in ovarian cancer detection and monitoring, whose serum level has a positive correlation with tumor stage. The aim of this study was to obtain a prediction metastasis equation in a group of patients with ovarian cancer based on Ca-125. Methods A 2-group comparative observational study was conducted at a single oncologic institution (SOLCA) in Cuenca-Ecuador. All patients who were diagnosed with ovarian cancer between January 1996 and December 2016 were included in the current study. Group 1 (G1) patients with the I and II International Federation of Gynecology and Obstetrics (FIGO) stage and Metastasis Group (MG), with III and IV stage, were subdivided. A logistic regression equation was performed to predict metastasis based on Logarithm of serum Ca-125 levels. Results We included 85 cases in G1 and 64 patients in MG, with 47.8 ± 15 years (G1) and 57.5 ± 13.6 years (MG) of age (P < 0.001). Mortality in G1 was 2 cases (3.1%) and 53 cases (62.4%) in MG (P < 0.001). The CA-125 serum level was 163.5 ± 236 in G1 and 1220.9 ± 1940 u / ml in MG (P < 0.001). The equation to predict metastasis = (Age*0.053) + [(Logarithm Ca-125 value) * 1.078] − 8.163 with an OR 2.940 (CI 95% 2.046–4.223) P < 0.001. The sensitivity of the equation was 82.4% and the specificity was 79.7%. Conclusions It is possible to predict the presence of metastasis in a group of patients with ovarian cancer based on Ca-125.

Abstract
BACKGROUND Cancer is widely believed to result from chronic inflammation, and red cell distribution width (RDW) and mean platelet volume (MPV) are considered as inflammatory markers for cancer. We investigated the values of RDW, MPV, and cancer antigen 125 (CA125), alone or in combination, for distinguishing between ovarian cancer and benign ovarian tumors. METHODS The study included 326 patients with ovarian cancer, 290 patients with benign ovarian tumors, and 162 control subjects. Hematologic tests were performed at initial diagnosis. RESULTS RDW was increased and MPV was decreased in the ovarian cancer group compared with the control and benign ovarian tumor groups. RDW was positively correlated and MPV was negatively correlated with cancer stage. Area under the curve (AUC) analysis for ovarian cancer versus benign ovarian tumors revealed that the specificity and sensitivity were increased for the combination of MPV and CA125 compared with either marker alone, and the specificity was increased for the combination of RDW and CA125, compared with either alone. The AUCs for RDW plus CA125 and MPV plus CA125 were significantly larger than for any of the markers alone. CONCLUSIONS In conclusion, combinations of the markers RDW, MPV, and CA125 may improve the differential diagnosis of ovarian cancer and benign ovarian tumors.

Abstract
Background: Ovarian cancer is the most common fatal malignancy of the gynecology tract. The purpose of this study was to compare serum levels of tumor markers cancer antigen 125 (CA125) and human epididymis protein 4 (HE4) in both healthy groups and patients with ovarian cancer. Materials and Methods: this case–control study was performed on Seyed Al-Shohada Hospital in Isfahan. Research on the treatment of 44 patients with ovarian cancer and 44 healthy controls was performed. CA125 and HE4 were measured in serum by sandwich ELISA method. Results: Average CA125 in ovarian cancer patients (83.30 ± 43.99 μ/ml) was significantly higher than in healthy controls (12.39 ± 5.50 μ/ml) (P < 0.001). Average HE4 in ovarian cancer patients (295.41 ± 133.33 PM) was significantly higher than in healthy controls (114.64 ± 17.31 PM) (P < 0.001). Conclusions: HE4 test is complementary of CA125 test in women with epithelial ovarian cancer. It is also used to study the disease process.

Abstract
Background To investigate dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) for assessing histopathological and molecular biological features in induced rat epithelial ovarian carcinomas (EOCs). Methods 7,12-dimethylbenz[A]anthracene (DMBA) was applied to induce EOCs in situ in 46 SD rats. Conventional MRI and DCE-MRI were performed to evaluate the morphology and perfusion features of the tumors, including the time-signal intensity curve (TIC), volume transfer constant (Ktrans), rate constant (Kep), extravascular extracellular space volume ratio (Ve) and initial area under the curve (IAUC). DCE-MRI parameters were correlated with histological grade, microvascular density (MVD), vascular endothelial growth factor (VEGF) and fraction of Ki67-positive cells and the serum level of cancer antigen 125 (CA125). Results Thirty-five of the 46 rats developed EOCs. DCE-MRI showed type III TIC more frequently than type II (29/35 vs. 6/35, p < 0.001) in EOCs. The two types of TIC of tumors had significant differences in the histological grade, MVD, expression of VEGF and Ki67, and the serum level of CA125 (all p < 0.01). Ktrans, Kep and IAUC values showed significant differences in different histological grades in overall and pairwise comparisons except for IAUC in grade 2 vs. grade 3 (all p < 0.01). There was no significant difference in Ve values among the three grade groups (p > 0.05). Ktrans, Kep and IAUC values were positively correlated with MVD, VEGF and Ki67 expression (all p < 0.01). Ve was not significantly correlated with MVD, VEGF expression, Ki67 expression and the CA125 level (all p > 0.05). Conclusions TIC types and perfusion parameters of DCE-MRI can reflect tumor grade, angiogenesis and cell proliferation to some extent, thereby helping treatment planning and predicting prognosis.

Abstract
Objective: To investigate the clinical significance of human epididymal secretory protein E4 (HE4) in combination with cancer antigen 125 (CA125) in the diagnosis of endometrial cancer. Methods: One hundred and fifty patients with endometrial cancer who were admitted to Binzhou People’s Hospital, Shandong, China, between June 2013 and July 2014, were enrolled and set as an endometrial cancer group; another one hundred patients with benign uterine diseases and one hundred healthy females were also enrolled. The serum was collected from the subjects for the detection of HE4 level. The level of CA125 was detected using electrochemiluminescence assay (ELISA). Receiver Operating Characteristic (ROC) curve was drawn to analyze the cutoff points of HE4 and CA125 levels for the diagnosis of endometrial cancer. The diagnostic efficacy based on the detection of the two indexes separately and jointly was evaluated. Results: The area under curve (AUC) for diagnosis of endometrial cancer based on HE4 was superior to that based on CA125 (0.819 vs 0.757). The optimal diagnosis cutoff point of HE4 and CA125 on the ROC curves was 92.21 pmol/L and 31.32KU/L, respectively. The sensitivity, Youden index, coincidence rate and negative predicted value of diagnosing endometrial cancer with HE4 in combination with CA125 (73.2%, 0.641, 83.5% and 83.4%) were significantly higher than those of diagnosing endometrial cancer with the two indexes separately. The ROC-AUC value of serum HE4 and CA125 was 0.749 and 0.528 respectively, much lower than that of HE4 in combination with CA125 (0.794; P<0.05). Conclusion: Serum HE4 and CA125 are the ideal marker combination for the diagnosis of endometrial cancer. HE4 combined with CA125 is beneficial to the diagnosis of endometrial cancer; hence it is worth promotion in clinical practice.

Abstract
OBJECTIVE To investigate the clinicopathological characteristics, treatment, survival, and prognosis of endometrial cancer in women aged ≤40 years. METHODS Women who underwent surgery for endometrial cancer at a single high-volume cancer center between January 1995 and December 2014 were retrospectively reviewed. Women aged >40, patients with missing data, and those who did not undergo surgical staging were excluded. Univariate and multivariate regression models were used to identify the risk factors for overall survival and progression-free survival. RESULTS A total of 40 patients with endometrial cancer were assessed. The median age at diagnosis was 38 (range, 21-40) years, and most of the uterine tumors found were early-stage (85%), low-grade (67.5%), and endometrioid carcinomas (97.5%). The median serum cancer antigen 125 level was 10.9 IU/mL (range, 3-1284 IU/mL). Optimal cytoreductive surgery was achieved in 35 patients (87.5%). All patients underwent total abdominal hysterectomy, and 97.5% of the patients underwent hysterectomy plus bilateral salpingo-oophorectomy. Among the total group of 40 patients, 21 (52.5%) underwent pelvic and para-aortic lymph node dissection, and 15 (37.5%) underwent only pelvic lymph node dissection. Multivariate analysis confirmed that a cancer antigen 125 level ≥35 was the only independent prognostic factor for both progression-free survival (hazard ratio, 22.997; 95% confidence interval, 1.783-296.536; p = 0.016) and overall survival (hazard ratio, 22.541; 95% confidence interval, 1.75-290.364; p = 0,017). CONCLUSIONS Our study demonstrated that a cancer antigen 125 level ≥ 35 is the only independent prognostic factor for both progression-free survival and overall survival in patients aged ≤40 years with endometrial cancer.

Abstract
OBJECTIVE To determine the efficacy of serum levels of cancer antigen 125 (CA125) and cancer antigen 19-9 (CA19-9), and the neutrophil-to-lymphocyte ratio (NLR) for diagnosis of mature cystic teratoma (MCT) with torsion. METHODS A retrospective medical record review was conducted of data for women who had undergone surgery for ovarian MCT at the First Affiliated Hospital of Wenzhou Medical University, China, between January 1, 2008, and January 1, 2015. Patients with torsion and a control group who underwent surgery on the same days were identified. Clinical characteristics and the serum levels of CA125, CA19-9, and the NLR were assessed. RESULTS The serum levels of CA125, CA19-9, and the NLR were higher in the torsion group (n=68) than in the control group (n=120; P≤0.001 for all). Receiver operating characteristic analysis indicated that the area under the curve for the combined use of CA125, CA19-9, and NLR was 0.978 (95% confidence interval 0.954-1.000; P<0.001). This combination had a diagnostic sensitivity of 93.9% and a specificity of 98.3%. Moreover, levels of these inflammatory markers were significantly increased among patients with large tumor diameters (P<0.01 for all). CONCLUSION The combined measurement of CA125, CA19-9, and the NLR provided an efficient method for the diagnosis of MCT with torsion.

Abstract
OBJECTIVES Ectopic pregnancies are among the leading causes of maternal morbidity and mortality in both developed and emerging nations, but tests for early, accurate, and convenient detection are lacking. STUDY DESIGN Between January 2013 and February 2015, 504 women with tubal pregnancy were prospectively recruited, and their clinical characteristics were recorded. Samples of peritoneal fluid were collected by culdocentesis, and venous blood was drawn from the antecubital vein. In samples from each source, levels of the following biochemical markers were measured: cancer antigen 125 (CA125), human chorionic gonadotropin (hCG), progesterone, vascular endothelial growth factor, and creatine kinase. RESULTS The ratios of biochemical markers in the peritoneal fluid and in the blood (Rp/v) were calculated. The median of Rp/v-CA125 and Rp/v-hCG were significantly lower in the ruptured ectopic pregnancy group than in the unruptured group. The optimal cutoff value to detect ectopic pregnancy rupture was 401.5U/mL as the upper limit for peritoneal CA125, with a sensitivity of 93.5% and specificity of 74.2%. The optimal cutoff value was 18.7 as the upper limit in the peritoneal fluid/blood ratio (Rp/v) of CA125, with a sensitivity of 77.5% and specificity of 68.4%. CONCLUSIONS In countries with poor access to laparoscopy, culdocentesis is useful. In this study, culdocentesis provided additional information for management of abdominal pain when laparoscopy is not available. The authors propose Rp/v cutoff values that can be used conveniently and quickly to diagnose ruptured ectopic pregnancies and bleeding, enabling rapid and appropriate therapeutic responses.

Abstract
Osteopontin (OPN) is currently one of the most studied serum biomarkers of ovarian cancer (OC). This meta-analysis aims to ascertain whether OPN is a useful diagnostic biomarker for OC and determine the overall diagnostic accuracy of OPN measurement when combined with cancer antigen 125 (CA125). A systematic literature search was conducted in Cochrane Library, PubMed, EMBASE, CBM, and China National Knowledge Infrastructure databases. Information was independently extracted by two investigators. The Quality Assessment for Studies of Diagnostic Accuracy tool was applied to examine the quality of eligible studies, and a bivariate model was used to calculate the pooled estimates. We identified 17 and 10 studies that evaluated the role of OPN alone and OPN combined with CA125 in diagnosing ovarian tumor, respectively. The overall diagnostic sensitivity and specificity of OPN in OC were 0.766 (95% CI 0.685-0.831) and 0.897 (95% CI 0.849-0.931), correspondingly. When OPN was combined with CA125, the sensitivity and specificity were 0.871 (95% CI 0.788-0.924) and 0.881 (95% CI 0.837-0.914), respectively. OPN is a useful tumor biomarker in future screening tests of OC and can be a promising adjunct to CA125. Additional studies with multicenter trials and carefully selected controls are needed to further verify the results.

Abstract
Icodextrin peritoneal dialysis (PD) solution has been shown to increase interleukin-6 (IL-6) levels in PD effluent as well as leukocyte and mesothelial cell count. Mesothelial cells release cancer antigen 125 (CA125), which is used as a marker of mesothelial cell mass. This 1-year prospective study was designed to compare peritoneal effluent cell population, its inflammatory phenotype and biocompatibility biomarkers IL-6 and CA125 between icodextrin (E) and glucose bicarbonate/lactate (P) based PD solutions. Using baseline peritoneal ultrafiltration capacity, 19 stable incident PD patients were allocated either to P only (N = 8) or to P plus E for the overnight dwell (N = 11). Flow cytometry was used to measure white blood cell count and differential and the expression of inflammatory molecules on peritoneal cells isolated from timed overnight peritoneal effluents. Compared to P, E effluent showed higher leukocyte (10.9 vs. 7.9), macrophages (6.1 vs. 2.5) and mesothelial cells (0.3 vs. 0.1)×10(6) /L count, as well as expression of HLA DR on mesothelial cells and IL-6 (320.5 vs. 141.2 pg/min) on mesothelial cells and CA125 appearance rate (159.6 vs. 84.3 IU/min), all P < 0.05. In the E group, correlation between IL-6 and CA125 effluent levels (r = 0.503, P < 0.05) as well as appearance rates (r = 0.774, P < 0.001) was demonstrated. No effect on systemic inflammatory markers or peritoneal permeability was found. Icodextrin PD solution activates local inflammation without systemic consequences so the clinical relevance of this observation remains obscure. Correlation between effluent IL-6 and CA125 suggests that CA125 might be upregulated due to inflammation and thus is not a reliable marker of mesothelial cell mass and/or biocompatibility.

Abstract
UNLABELLED ♦ BACKGROUND AND OBJECTIVES Cancer antigen 125 (CA125) reflects the mesothelial cell mass lining the peritoneal membrane in individual patients. A decline or absence of mesothelial cells can be observed with duration of peritoneal dialysis (PD) therapy. Technique failure due to peritoneal membrane malfunction becomes of greater importance after 2 years of PD therapy in comparison to the initial period. In this study, we aimed to investigate the association between effluent CA125 and technique survival in incident PD patients with a PD therapy period of at least 2 years. ♦ METHODS Within the Netherlands Cooperative Study on the Adequacy of Dialysis (NECOSAD), a Dutch multicenter cohort including 2,000 incident dialysis patients, we identified all PD patients who developed technique failure after 2 years of PD therapy and randomly selected a number of them as cases in a nested case-control study. Controls were PD patients matched on follow-up time without technique failure. Cases and controls were included if they had a dialysate specimen available within 24 ± 6 months of PD therapy for retrospective CA125 determinations. Odds ratios for technique failure related to CA125 were estimated. We used a prospective cohort with incident PD patients from the Academic Medical Center-University of Amsterdam (AMC) for replication of effect estimates. In these patients, absolute risk of technique failure was estimated and related to effluent CA125 levels. ♦ RESULTS A total of 38 PD patients were selected from the NECOSAD cohort. From the AMC cohort as replication cohort, 91 PD patients were included. Incidence rates of PD technique failure per 100 patient-years were 16.3 in the NECOSAD cohort and 12.9 in the AMC cohort. In both study populations CA125 levels below 12 - 14 kU/L were associated with an increased risk for technique failure. Technique survival rates in the AMC were 87% in patients with levels of CA125 above 12.1 kU/L and 65% for those with CA125 levels below this threshold after a maximum 5-year follow-up. ♦ CONCLUSIONS Patients with high CA125 levels after at least 2 years of PD therapy tend to have better technique survival than patients with low CA125 levels. These results support the importance of effluent CA125 as a risk factor for dropout in long-term PD therapy.

Abstract
CONTEXT The sensitivity and specificity of blood microRNA-421 (miR-421) as a gastric cancer (GC) biomarker has not been determined. OBJECTIVE To investigate the diagnostic value of blood miR-421 as GC biomarker. MATERIALS AND METHODS miR-421 in serum and peripheral blood mononuclear cells (PBMCs) of 90 GC patients and 90 controls was detected by quantitative real-time PCR. The correlation of miR-421 to GC clinicopathological features as well as the diagnostic value of miR-421 comparing to carcinoembryonic antigen (CEA) and cancer antigen 125 (CA-125) were analyzed. RESULTS miR-421 increased significantly in GC patients than in controls. miR-421 in either serum or PBMCs had higher sensitivity and specificity than CEA and CA-125 in GC diagnosis. The GC positive prediction rates of miR-421 were also significantly higher than those of CEA and CA-125. DISCUSSION AND CONCLUSIONS miR-421 in serum or PBMCs may be a new potential diagnostic biomarker for GC.

The concentration or appearance rate of cancer antigen 125 (CA125) in peritoneal dialysis (PD) effluent has been used for many years as a biomarker for mesothelial cell mass in patients on PD. However, this marker has limitations, and emerging evidence has raised doubts as to its significance. This review explores our current understanding of CA125, its prominent role in studies of "biocompatible" PD solutions, and the ongoing uncertainty concerning its interpretation as a measure of mesothelial cell health.
