Gastric Type Endocervical Adenocarcinoma With Concurrent High-Grade Squamous Intraepithelial Lesion: A Clinicopathologic Study of Three Patients.

We investigate gastric-type endocervical adenocarcinoma (ECA), a prominent HPV-independent adenocarcinoma, and its coexistence with high-grade squamous intraepithelial lesion (HSIL) through the examination of three such tumors. In this study, we conducted an in-depth review of three patients with gastric-type ECA, each associated with high-risk HPV infection as detected on Pap smears. We detailed the clinical and pathological features of each patient and utilized RNAscope for high-risk HPV testing to ascertain HPV status in both gastric-type ECA and HSIL components. Immunohistochemistry with p16, p53, and other biomarkers was also applied. The gastric-type ECA component, characterized by well-differentiated glands with abundant, clear to eosinophilic cytoplasm, distinct cellular borders, and pale nuclei with conspicuous nucleoli, tested negative for both p16 and high-risk HPV, unlike the concurrent HSIL components which were positive. Additionally, two tumors showed aberrant p53 protein expression in the gastric-type ECA areas, and elevated carbohydrate antigen19-9 levels were noted in two patients. Treatment consisted of total abdominal hysterectomy and bilateral salpingo-oophorectomy, supplemented by chemotherapy and/or radiation, with disease-free intervals of 24, 12, and 40 months post-treatment, respectively. This study highlights the critical need for meticulous diagnostic protocols that combine morphological examination, immunohistochemistry, and HPV RNA in situ hybridization. The rarity of gastric-type ECA coexisting with HPV infection underscores the necessity for continuous research and vigilant monitoring in the field of gynecological oncology.

CA125 Kinetics as a Potential Biomarker for Peritoneal Metastasis Progression following Taxane-Plus-Ramucirumab Administration in Patients with Advanced Gastric Cancer.

Currently, no established marker exists for predicting peritoneal metastasis progression during chemotherapy, although they are major interruptive factors in sequential chemotherapy in patients with advanced gastric cancer (AGC). This multicenter retrospective study was conducted from June 2015 to July 2019, analyzing 73 patients with AGC who underwent taxane-plus-ramucirumab (TAX/RAM) therapy and had their serum carbohydrate antigen 125 (CA125) concentrations measured. Of 31 patients with elevated CA125 levels above a cutoff of 35 U/mL, 25 (80.6%) had peritoneal metastasis. The CA125 concentrations before TAX/RAM treatment were associated with ascites burden. The overall survival was significantly shorter in the CA125-elevated group. CA125 kinetics, measured at a median of 28 days after chemotherapy, were associated with the ascites response (complete or partial response: -1.86%/day; stable disease: 0.28%/day; progressive disease: 2.33%/day). Progression-free survival in the CA125-increased group, defined by an increase of 0.0067%/day using receiver operating characteristic curve analysis, was significantly poorer among patients with peritoneal metastases. In conclusion, this study highlights that CA125 kinetics can serve as an early predictor for the progression of peritoneal metastasis during TAX/RAM treatment.

The Effect of Diabetic Ketoacidosis and Hyperosmolar Hyperglycemic on the Metabolic Tumor Markers: A Real-World Retrospective Study.

Serum tumor markers have been discovered to be elevated in individuals with diabetes mellitus (DM); however, their significance in diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemia (HHS) is unknown. We evaluated these indicators in the patients with DKA and HHS. We retrospectively collected the laboratory data of 565 diabetic patients from Shanghai Pudong Hospital between Jan, 2019 and May, 2023, including 300 patients with type 2 diabetes mellitus (T2DM), 206 with DKA, and 59 with HHS. Serum tumor biomarkers and further clinical laboratory tests were compared among the three groups. Patients with conspicuous tumor evidence were excluded from the study. We found significantly higher levels of carbohydrate antigen 199 (CA199) in DKA (p<0.01), carcinoembryonic antigen (CEA), complex prostate specific antigen (CPSA) (p<0.01), prostate specific antigen (PSA) (p<0.05) in HHS, as well as the plasma lipid profile, iron, and electrolytes, in addition to decreased thyroid function, hepatic and renal function, and cardiac function (p<0.05). A Spearman correlational study revealed that osmolar levels were significantly positively correlated with myoglobin (MYO) and cardiac troponin I (cTNI), whereas serum iron concentration (r=0.520) was positively correlated with CEA levels in HHS. pH was negatively correlated with CA199 (r=-0.195), while HbA1c (r=0.22), globin (r=0.341), and total cholesterol (TC) (r=0.191) were positively correlated with elevated CA199 levels. Moreover, the multilinear regression investigation identified osmolarity as a significant determinant for CEA, as well as other parameters, and all proved to be proper predictors for CEA in HHS via ROC curve establishment. Elevated CA199 levels in DKA were associated with acidosis, whereas HHS with elevated CEA levels may be related to iron homeostasis and could be predicted via the osmolar degree and other predictors.

CA125-Associated Activated Partial Thromboplastin Time and Thrombin Time Decrease in Patients with Adenomyosis.

Adenomyosis patients are in a hypercoagulable state, and studies have shown that carbohydrate antigen125 (CA125) may relate to the hypercoagulability and thrombosis of patients with adenomyosis, but there is still a lack of clarity regarding the changes in CA125-related coagulation indicators. This study was to explore the changes and influencing factors of CA125-related coagulation parameters in patients with adenomyosis. Retrospective observational study conducted on 200 patients with adenomyosis (AM group), 240 patients with uterine leiomyoma (LM group) and 81 patients with cervical intraepithelial neoplasia (CIN)-III (control group), of which the coagulation parameters were detected by clinical blood sample collection and statistical method analysis and informed consent was obtained. The level of CA125 in the AM group was significantly higher than that in the LM group and control group. However, thrombin time (TT) shortened in the AM group when compared with the LM and control group. Activated partial thromboplastin time (APTT) in the AM group was shorter than in the control group. Multivariate logistic regression analysis found that adenomyosis was associated with CA125 level (OR=323.860, 95% CI 90.424-1159.924, P<0.001), APTT (OR=1.295, 95% CI 1.050-1.598, P=0.016), TT (OR=0.642, 95% CI 0.439-0.938, P=0.022), menorrhagia (OR=7.363, 95% CI 2.544-21.315, P<0.001), dysmenorrhea (OR=22.590, 95% CI 8.185-62.347, P<0.001). Correlation analysis revealed that APTT (r= -0.207) and TT (r = -0.174) were negatively correlated with the level of CA125. The shortening of CA125-related APTT and TT indicates that it is meaningful to detect coagulation parameters of patients with elevated CA125 levels early, dysmenorrhea and menorrhagia, and maybe further discover the hypercoagulability and prevent the occurrence of thrombus in adenomyosis.

The Clinical Implications of Serum Carbohydrate Antigen 19-9 Levels in Patients with Nontuberculous Mycobacteria Pulmonary Disease.

Serum carbohydrate antigen 19-9 (CA19-9) levels can increase in nontuberculous mycobacteria pulmonary disease (NTM-PD), and the levels correlate with disease activity. We compared the clinical characteristics of NTM-PD patients with and without elevated CA19-9 levels and evaluated its association with antibiotic response in a retrospective study of NTM-PD patients diagnosed between January 1994 and December 2020. We analyzed 1112 patients who had serum CA19-9 measured: 322 with elevated CA19-9 and 790 with normal CA19-9. The erythrocyte sedimentation rate and C-reactive protein levels were significantly higher in the elevated CA19-9 group (p < 0.001 and p = 0.029, respectively). The 1-year culture conversion rate after antibiotics did not differ between the elevated (n = 206) and normal (n = 377) CA19-9 groups (80% vs. 72%, p = 0.055). Analysis of a subset of 434 patients revealed that current smoking, bronchiectasis, acid-fast bacilli smear positivity, and the M. abscessus strain significantly reduced microbiological cure rates. Serum CA 19-9 levels did not have a significant association with microbiological cure in a multivariate analysis. These findings suggest that the role of serum CA19-9 in predicting antibiotic treatment outcomes is limited, and that elevated CA19-9 does not necessarily indicate a poor outcome.

Differentiating mass-forming intrahepatic cholangiocarcinoma from atypical hepatocellular carcinoma using Gd-EOB-DTPA-enhanced magnetic resonance imaging combined with serum markers in at-risk patients with hepatitis B virus.

The precise differentiation of intrahepatic cholangiocarcinoma (ICC) from atypical hepatocellular carcinoma (HCC) is vital for treatment strategy and prognostic prediction. In clinical practice, nearly 40% of HCCs demonstrate atypical manifestations, particularly HCCs with rim arterial phase hyperenhancement (APHE), which is challenging to differentiate from mass-forming ICC. Thus, we aimed to develop a diagnostic regimen of gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA) contrast-enhanced magnetic resonance imaging (MRI) combined with serum tumor markers in differentiating mass-forming ICC from atypical HCC in at-risk patients with the hepatitis B virus (HBV). This study enrolled 129 patients with pathologically proven mass-forming ICCs (n=53) and atypical HCCs (n=76) who had undergone preoperative Gd-EOB-DTPA contrast-enhanced MRI. The clinical data and imaging findings were analyzed. Univariate and multivariate logistic analyses were performed to identify the independent predictors for differentiating mass-forming ICCs from atypical HCCs. The diagnostic performance was evaluated using receiver operating characteristic (ROC) curves, and DeLong test was used to compare the areas under curves of all independent predictors. Univariate logistic regression analysis revealed normal alpha fetoprotein (AFP), elevated carbohydrate antigen 19-9 (CA19-9) level, elevated carcinoma embryonic antigen (CEA) level, central hyperintensity on T2-weighted imaging (T2WI), central hypointensity on T2WI, and targetoid sign on hepatobiliary phase (HBP) and targetoid restriction on diffusion-weighted imaging (DWI) were more likely to be significant predictors favoring mass-forming ICCs (all P values <0.05). In contrast, multifocal hyperintensity on T2WI and capsule sign were more frequently seen in patients with atypical HCC (all P values <0.05). Multivariate analysis revealed normal AFP, elevated CA19-9 level, targetoid sign on HBP, and targetoid restriction on DWI (all P=0.001) were independent predictors for differentiating mass-forming ICCs from atypical HCCs; DeLong test showed that the area under curve (AUC) increased to 0.949 when the above predictors were combined (all P values <0.05), and the sensitivity, specificity, and accuracy of the combined independent predictors were 88.7%, 93.4%, and 91.5%, respectively. A diagnostic regimen integrating tumor markers (AFP, CA19-9) and imaging biomarkers (targetoid restriction on DWI and/or targetoid sign on HBP) using Gd-EOB-DTPA-enhanced MRI could help to differentiate mass-forming ICCs from atypical HCCs and achieve high diagnostic performance of mass-forming ICCs in at-risk patients with the HBV. Mass-forming intrahepatic cholangiocarcinoma (mass-forming ICC); atypical hepatocellular carcinoma (atypical HCC); magnetic resonance imaging (MRI); gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA); hepatobiliary phase (HBP).

Preoperative serum CA125 level is a good prognostic predictor in patients with intrahepatic cholangiocarcinoma after hepatectomy: A single-center retrospective study.

Serum carbohydrate antigen 125 (CA125) is associated with the prognosis of various malignancies, including ovarian and pancreatic cancer. The relationship between preoperative serum CA125 level and the survival of patients with intrahepatic cholangiocarcinoma (ICC) has not been fully studied. The aim of this study was to explore the prognostic value of CA125 in ICC after hepatectomy. We retrospectively reviewed the clinicopathological data of 178 ICC patients who underwent hepatic resection. Receiver operating characteristic analyses were performed to estimate the relationships of serum CA125, α-fetoprotein, carcinoembryonic antigen (CEA), and carbohydrate antigen 19-9 with the prognosis of ICC. The predictive value of CA125 for the prognosis of ICC patients was demonstrated by univariate analyses and Cox proportional hazards models. CA125 was correlated with tumor size, differentiation, capsulation, tumor node-metastasis stage, recurrence, and CEA. Univariate analysis indicated that CA125, sex, tumor number, tumor size, differentiation, surgical resection margin, tumor node metastasis stage, and CEA were risk factors for both the overall survival and the disease-free survival of ICC patients. Cox proportional hazards models showed that preoperative elevated CA125, a tumor size > 5 cm, and an R1 surgical resection margin were independent prognostic predictors of overall survival and disease-free survival. CA125 also had strong predictive value for the prognosis of different ICC subgroups, including patients without lymph node metastasis and with elevated carbohydrate antigen 19-9 levels. Preoperative elevated serum CA125 level is a noninvasive, simple, and reliable indicator of the prognosis of ICC patients after hepatectomy.

Prognostic significance of carbohydrate antigen 125 in stage D heart failure

BackgroundThe predictive value of carbohydrate antigen 125 (CA125) has not been examined in stage D heart failure (HF) patients, regardless of left ventricular ejection fraction (LVEF). We sought to quantify the prognostic usefulness in predicting death and HF readmission in this cohort.MethodsAccording to CA125 levels above and below the median (65.7 U/ml), 176 stage D HF patients including more than half (50.6%) had LVEF > 40% were divided into 2 groups.ResultsA total of 106 (60.2%) deaths and 102 deaths due to the cardiovascular disease were identified. All-cause death/HF readmission and MACE occurred in 157 patients (89.2%) during 18 months (16–20) of follow-up. By the Kaplan–Meier method, subjects with CA125 ≥ 65.7 U/ml exhibited higher 1-year mortality rate (59.3% vs. 31.0%, P < 0.001) and 1-year death/HF rehospitalization rate (94.2% vs. 80.6%, P < 0.001). In univariate Cox analysis, CA125 (categorized) was a significant prognostic factor for all-cause death, cardiovascular mortality, death/HF readmission and MACE. Based on multivariate Cox analysis, elevated CA125 was still significant for all-cause death, cardiovascular mortality, death/HF readmission and MACE.ConclusionsIn stage D HF patients, elevated CA125 levels were highly predictive of all-cause death, cardiovascular mortality, all-cause death/HF readmission and MACE, which can be used for better risk stratification.

The Indicative Value of Serum Tumor Markers for Metastasis and Stage of Non-Small Cell Lung Cancer.

Simple SummaryThis study recruited 3272 non-small cell lung cancer (NSCLC) cases to analyze the predictive abilities of serum tumor markers (CEA, SCC-Ag, CYFRA 21-1, NSE, ProGRP, TPSA and CA199) for metastasis and clinical stage, and found that tumor marker levels may be indicative of tumor metastasis (intrapulmonary, lymphatic and distant metastasis) and stage. Increased CEA and CA199 provided an accurate prediction of intrapulmonary and distant metastasis. Increased CEA, CYFRA 21-1 and CA199 provided an accurate prediction of lymphatic metastasis and higher tumor stage. Combined detection of serum tumor markers can indicate tumor metastasis and stage in NSCLC patients.Objective: This study aimed to explore the roles of serum tumor markers for metastasis and stage of non-small cell lung cancer (NSCLC). Methods: This study recruited 3272 NSCLC patients admitted to the Tianjin Union Medical Center and the Tianjin Medical University Cancer Institute and Hospital. The predictive abilities of some serum tumor markers (carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCC-Ag), cytokeratin-19 fragment (CYFRA 21-1), neuron-specific enolase (NSE), pro-gastrin-releasing peptide (ProGRP), total prostate-specific antigen (TPSA) and carbohydrate antigen 199 (CA199)) for NSCLC metastasis (intrapulmonary, lymphatic and distant metastasis) and clinical stage were analyzed. Results: Tumor markers exhibited different numerical and proportional distributions in NSCLC patients. Elevated CEA, CYFRA 21-1 and CA199 levels were indicative of tumor metastasis and stage. Increased CEA and CA199 provided an accurate prediction of intrapulmonary and distant metastasis with the area under the receiver operator characteristic curve (AUC) of 0.69 both (p < 0.001); Increased CEA, CYFRA 21-1 and CA199 provided an accurate prediction of lymphatic metastasis with the AUC of 0.62 (p < 0.001). Conclusion: Combined detection of serum tumor markers can indicate tumor metastasis and stage in NSCLC patients.

Importance of triple tumor markers as biomarkers in patients with pancreatic ductal adenocarcinoma.

There is an urgent need to establish biomarkers for the treatment of pancreatic ductal adenocarcinoma (PDAC). The aim of this study was to investigate the usefulness of the combined assessment of carbohydrate antigen 19-9 (CA19-9), carcinoembryonic antigen (CEA), and duke pancreatic monoclonal antigen type 2 (DUPAN-2) in PDAC. We retrospectively investigated the impact of three tumor markers on overall survival (OS) and recurrence-free survival (RFS). Patients were classified into two groups: upfront surgery (US) and neoadjuvant chemoradiation (NACRT) groups. In total, 310 patients were evaluated. In the US group, patients who had all three elevated markers showed a significantly worse prognosis than the others (median: 16.4months, P=.005). In the NACRT group, patients who had elevated CA 19-9 and CEA levels after NACRT had significantly worse prognosis than the others (median: 26.2months, P < .001). The elevated DUPAN-2 levels before NACRT were associated with significantly worse prognosis than normal levels (median: 44.0 vs 59.2 months, P=.030). Patients who had elevated DUPAN-2 levels before NACRT with elevated CA 19-9 and CEA levels after NACRT showed extremely poor RFS (median: 5.9months). Multivariate analysis revealed that a modified triple-positive tumor marker indicating elevated DUPAN-2 levels before NACRT and elevated CA19-9 and CEA levels after NACRT was an independent prognostic factor of OS (hazard ratio: 2.49, P=.007) and RFS (hazard ration: 2.47, P=.007). The combined evaluation of three tumor markers may provide useful information for the treatment of patients with PDAC.

Prognostic Role of Carcinoembryonic Antigen and Carbohydrate Antigen 19-9 in Stage IV Colorectal Cancer.

We investigated the association of the levels of serum carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) with prognosis in patients with stage IV colorectal cancer at diagnosis. In this multicenter retrospective cohort study, patients with serum CEA and CA19-9 measured at diagnosis of stage IV colorectal cancer were included. The cutoff values were 5 ng/ml for CEA and 37 U/ml for CA19-9. Patients were categorized into four groups: those with normal levels for both CEA and CA19-9; those with only an elevated CEA level; those with only an elevated CA19-9 level; and those with elevated levels of both. A total of 825 patients were included. Among them, 132 (16.0%) had normal levels for both markers, 258 (31.3%) had an elevated CEA level only, 33 (4.0%) had an elevated CA19-9 level only, and 402 (48.7%) had elevated levels of both CEA and CA19-9. Compared with patients with normal levels for both CEA and CA19-9, the multivariate hazard ratio for overall survival was 1.24 (95% confidence interval=0.95-1.62, p=0.12) for those with elevated CEA only, 2.04 (95% confidence interval=1.31-3.17, p=0.002) for those with elevated CA19-9 only, and 1.82 (95% confidence interval=1.41-2.32, p<0.001) in those with elevation of both CEA and CA19-9. Elevation of CEA alone was not prognostic. Elevation of only CA19-9 at diagnosis was associated with a worse prognosis in patients with stage IV colorectal cancer. The combined measurement of CEA and CA19-9 can be helpful as a predictive tool for the prognosis of stage IV colorectal cancer.

Elevated preoperative CA125 is associated with poor survival in patients with metastatic colorectal cancer undergoing primary tumor resection: a retrospective cohort study.

BackgroundThe impact of the preoperative carbohydrate antigen 125 (CA125) level on the survival of metastatic colorectal cancer (CRC) patients undergoing primary tumor resection (PTR) remains uncertain. The aim of this study was to assess the prognostic value in overall survival (OS) and cancer-specific survival (CSS) between patients with and without an elevated preoperative CA125 level.MethodsAll metastatic CRC patients receiving PTR between 2007 and 2017 at the Sixth Affiliated Hospital of Sun Yat-sen University (Guangzhou, China) were retrospectively included. OS and CSS rates were compared between patients with and without elevated preoperative CA125 levels.ResultsAmong 326 patients examined, 46 (14.1%) exhibited elevated preoperative CA125 levels and the remaining 280 (85.9%) had normal preoperative CA125 levels. Patients with elevated preoperative CA125 levels had lower body mass index, lower preoperative albumin level, lower proportion of preoperative chemotherapy, higher carcinoembryonic antigen and carbohydrate antigen 19–9 (CA19–9) levels, poorer differentiation, and more malignant histopathological type than patients with normal preoperative CA125 levels. In addition, patients with elevated preoperative CA125 levels exhibited more advanced pathological T and N stages, more peritoneal metastasis, and more vessel invasion than patients with normal preoperative CA125 levels. Moreover, the primary tumor was more likely to be located at the colon rather than at the rectum in patients with elevated CA125 levels. Both OS and CSS rates in patients with elevated preoperative CA125 levels were significantly lower than those in patients with normal preoperative CA125 levels. Multivariate Cox regression analysis revealed that an elevated preoperative CA125 level was significantly associated with poor prognosis in metastatic CRC patients undergoing PTR. The hazard ratio (HR) in OS was 2.36 (95% confidence interval [CI], 1.67–3.33, P < 0.001) and the HR in CSS was 2.50 (95% CI, 1.77–3.55, P < 0.001). The survival analysis stratified by peritoneal metastasis also demonstrated that patients with elevated preoperative CA125 levels had lower OS and CSS rates regardless of peritoneal metastasis.ConclusionBased on an analysis of metastatic CRC patients undergoing PTR, an elevated preoperative CA125 level was associated with poor prognosis, which should be taken into consideration in clinical practice.

Ratio of CA19-9 Level to Total Tumor Volume as a Prognostic Predictor of Pancreatic Carcinoma After Curative Resection.

Background: Pancreatic ductal adenocarcinoma (PDAC) is known to have a poor prognosis, early local invasion, and distant metastasis. Surgical resection is the most effective treatment, and tumor recurrence can be the key factor affecting the surgical outcome. Serum carbohydrate antigen 19-9 (CA19-9) is a tumor marker with high sensitivity to pancreatic cancer; elevated CA19-9 levels often indicate poor biological behavior. Tumor size is also a crucial factor that affects the prognosis. Therefore, we developed a program to evaluate the effect of the ratio of CA19-9 to total tumor volume (CA19-9/TTV) as a prognostic marker on tumor recurrence and long-term survival in patients with PDAC following pancreaticoduodenectomy (PD). Methods: Data from 200 patients who underwent PD for PDAC were retrospectively analyzed. CA19-9/TTV was calculated according to preoperative CA19-9 and TTV, and patients were divided into two groups according to the optimal cut-off value. Univariate and multivariate analyses were performed on the clinicopathological data to screen the risk factors affecting postoperative recurrence and long-term prognosis of patients with PDAC undergoing PD. Results: The receiver operating characteristic curve showed that the best cut-off value was 5.62 (area under curve [AUC], 0.633; 95% CI: 0.548-0.718). Multivariate analysis showed that tumor differentiation and CA19-9/TTV were independent risk factors for the long-term prognosis of PDAC (P = 0.004, P = 0.007), as well as for tumor recurrence (P = 0.008, P = 0.008). Conclusion: CA19-9/TTV is an independent risk factor for the prognosis of PDAC and may be a new marker for lower survival benefits.

Elevated CA125 is Related to Stroke Due to Cancer- Associated Hypercoagulation

BackgroundCancer-associated hypercoagulation is one of the major pathophysiological mechanisms of stroke in cancer patients. Carcinomatous mucins are considered to play an important role in cancer-associated hypercoagulation. Therefore, carbohydrate antigen-125 (CA125), which is a typical mucin molecule and mucin-producing tumor marker, may be related to stroke due to cancer-associated hypercoagulation. AimsWe aimed to clarify the association of CA125 with a hypercoagulable state in acute stroke patients with active cancer. MethodsWe studied 77 acute ischemic stroke patients with active cancer who had undergone CA125 measurement. The study patients were categorized into hypercoagulation or non-hypercoagulation groups. The hypercoagulation group was defined as stroke patients with a D-dimer value exceeding 3 µg/mL and multiple vascular territory infarcts. Elevation of tumor markers was defined as values more than twice the upper limit of the normal range. ResultsForty-five (58%) and 32 (42%) patients were classified into hypercoagulation and non-hypercoagulation groups, respectively. The hypercoagulation group showed elevated CA125 and CEA levels, no history of hypertension, and pancreatic cancer more frequently, and higher CRP values, lower hemoglobin values, longer prothrombin time and lower platelet counts than the non-hypercoagulation group. In multivariable analysis, only elevation of CA125 was independently associated with the hypercoagulation group (adjusted odds ratio: 5.59 [95% confidence interval]: 1.33-26.41). ConclusionsCA125, a tumor marker for mucin-producing tumors, was related to stroke due to cancer- associated hypercoagulation. CA125 may be a potential biomarker for cancer-associated hypercoagulation.

Propofol-Based Total Intravenous Anesthesia is Associated with Better Survival than Desflurane Anesthesia in Epithelial Ovarian Cancer Surgery: A Retrospective Cohort Study.

Background: Previous studies have shown that anesthetic techniques can affect outcomes of cancer surgery. We investigated the association between anesthetic techniques and patient outcomes after elective epithelial ovarian cancer surgery. Methods: This was a retrospective cohort study of patients who received elective open surgery for epithelial ovarian cancer between January 2009 and December 2014. Patients were grouped according to the administration of propofol or desflurane anesthesia. Kaplan–Meier analysis was performed, and survival curves were constructed from the date of surgery to death. Univariate and multivariate Cox regression models were used to compare hazard ratios for death after propensity matching. Subgroup analyses were performed for age, body mass index, preoperative carbohydrate antigen-125 level, International Federation of Gynecology and Obstetrics staging, and operation and anesthesia time. Results: In total, 165 patients (76 deaths, 46.1%) who received desflurane anesthesia and 119 (30 deaths, 25.2%) who received propofol anesthesia were eligible for analysis. After propensity matching, 104 patients were included in each group. In the matched analysis, patients who received propofol anesthesia had better survival with a hazard ratio of 0.52 (95% confidence interval, 0.33–0.81; p = 0.005). Subgroup analyses also showed significantly better survival with old age, high body mass index, elevated carbohydrate antigen-125 level, advanced International Federation of Gynecology and Obstetrics stage, and prolonged operation and anesthesia time in the matched propofol group. In addition, patients administered with propofol anesthesia had less postoperative recurrence and metastasis than those administered with desflurane anesthesia in the matched analysis. Conclusion: Propofol anesthesia was associated with better survival in patients who underwent elective epithelial ovarian cancer open surgery. Prospective studies are warranted to evaluate the effects of propofol anesthesia on oncological outcomes in patients with epithelial ovarian cancer.

Plasma carbohydrate antigen-125 for prediction of atrial fibrillation recurrence after radiofrequency catheter ablation

BackgroundElevated plasma carbohydrate antigen-125 (CA-125) levels are strongly associated with new-onset atrial fibrillation (AF) and heart failure, but the relationship between plasma CA-125 level and AF recurrence following radiofrequency catheter ablation (RFCA) remains poorly investigated. We aimed to assess whether elevated CA-125 levels are related to long-term AF recurrence following RFCA.MethodsPreoperative CA-125 levels were determined in AF patients undergoing initial RFCA. Multivariate-adjusted Cox models were constructed to determine the relationship between CA-125 levels and AF recurrence. Multivariate logistic regression analyses were performed to determine predictors of AF recurrence.ResultsOf the 353 enrolled patients, 85 patients (24.1%) had AF recurrence at the 12-month follow-up. These patients had significantly higher baseline CA-125 levels than those without AF recurrence [(18.71 ± 12.63) vs. (11.27 ± 5.40) U/mL, P < 0.001]. The incidence of AF recurrence across quartiles 1–4 of CA-125 was 11.5%, 13.3%, 21.6% and 50.0%, respectively (P-trend < 0.001). The adjusted hazard ratios (aHRs) for AF recurrence across quartiles 1–4 of CA-125 were 1.00 (reference), 1.085 (95% CI, 0.468–2.520), 1.866 (95% CI, 0.867–4.019), and 4.246 (95% CI, 2.113–8.533), respectively (P-trend < 0.001). A similar effect was obtained when CA-125 was studied as continuous data (aHR per unit increase in LnCA-125, 3.225, 95% CI, 2.258–4.606; P < 0.001). When a predefined CA-125 cut-off of 13.75 U/mL was established, patients with CA-125 ≥ 13.75 U/mL had a higher risk of recurrent AF than those with CA-125 < 13.75 U/mL (aHR, 3.540, 95% CI, 2.268–5.525, P < 0.001). Multivariate analysis revealed CA-125, high-sensitivity C-reactive protein, and left atrium anteroposterior diameter as independent risk factors for AF recurrence.ConclusionsElevated preoperative CA-125 levels are related to a higher risk of AF recurrence and can independently predict AF recurrence following RFCA.

Elevated preoperative CA125 levels predicts poor prognosis of hilar cholangiocarcinoma receiving radical surgery

BackgroundPreoperative serum carbohydrate antigen 125 (CA125) is used to judge the diagnosis and prognosis of various tumors. However, the relationship between preoperative serum CA125 and prognosis of hilar cholangiocarcinoma (HCCA) has not been proven. This study aims to evaluate preoperative serum CA125 in predicting the prognosis of HCCA after resection. MethodsA total of 233 patients after radical resection of HCCA were included. The associations between the levels of preoperative serum CA125 and the clinicopathological characteristics of patients were analyzed. Survival curves were calculated using the Kaplan–Meier method. Univariate and multivariate Cox regression models were used to identify independent risk factors associated with recurrence-free survival (RFS) and overall survival (OS). ResultsAmong 233 patients, 198 (84.97%) with normal CA125 levels (≤35 U/mL) had better OS and RFS than 35 (15.02%) patients with higher CA125 levels (>35 U/mL). Preoperative serum CA125 was significantly correlated with tumor size, Bismuth–Corlette classification, microvascular invasion and carcinoembryonic antigen (CEA) (p < 0.001, p = 0.040, p = 0.019 and p = 0.042, respectively). The results of multivariable Cox regression showed that preoperative serum CA125 >35 U/mL (p = 0.002, HR = 1.910 for OS; p = 0.006, HR = 1.755 for RFS), tumor classification (p < 0.001, HR = 2.110 for OS; p = 0.006, HR = 1.730 for RFS), lymph node metastasis (p < 0.001, HR = 1.795 for OS; p < 0.001, HR = 1.842 for RFS) and major vascular invasion (p = 0.002, HR = 1.639 for OS; p = 0.005, HR = 1.547 for RFS) were independent risk factors for both OS and RFS. ConclusionsPreoperative serum CA125 is a good tumor marker for predicting prognosis after radical surgery for HCCA.

Effectiveness of Adjuvant Therapy in Patients with Pancreatic Cancer Who Underwent Neoadjuvant Therapy.

Neoadjuvant therapy (NAT) is used to treat not only advanced pancreatic cancer but also resectable lesions. The present study investigated the effectiveness of postoperative adjuvant chemotherapy for patients with pancreatic cancer who underwent surgical resection after NAT. Patients who underwent macroscopically curative resection after NAT for pancreatic cancer were enrolled. Adjuvant chemotherapy was defined as at least 1 cycle of planned chemotherapy within 3 months after the date of surgery and included S-1, gemcitabine, or both. We retrospectively examined the effect of adjuvant chemotherapy on overall survival (OS) and recurrence-free survival (RFS) as a function of patients' clinicopathological factors. Ninety-seven patients were included in the study, of which 68 (70.1%) underwent adjuvant chemotherapy. Administration of adjuvant chemotherapy was significantly associated with prolonged OS and RFS in patients whose elevated levels of carbohydrate antigen 19-9 or duke pancreatic monoclonal antigen type-2 did not normalize after NAT. In patients with pathological lymph node metastasis, the administration of adjuvant chemotherapy was significantly associated with longer OS but did not improve PFS. Postoperative adjuvant chemotherapy was associated with prolonged postoperative survival in patients with pancreatic cancer who did not sufficiently respond to NAT as judged by tumor marker expression.

Benign Ovarian Cysts with Raised CA-125 Levels: Do We Need to Evaluate the Fallopian Tubes?

Objectives It is not clearly known whether some benign (simple) ovarian cysts can convert into cancerous cysts. Size of cyst and wall abnormalities do predict the potentiality of malignancy. Not many studies have been done to explore the malignant potential of large-sized (> 5 cm) unilocular ovarian cysts without wall abnormalities. This study evaluated the correlation between ultrasonographic size of benign ovarian cysts and carbohydrate antigen 125 (CA-125) levels. Methodology Sixty (60) premenopausal women were recruited for the study preoperatively, based on transvaginal ultrasound (TVUS) findings present in the case record sheet received along with the CA-125 sample in the biochemistry laboratories. Those cases with elevated CA-125 levels were selected, where patients had unilocular ovarian cysts without wall abnormalities. CA-125 was done using ECLIA methodology (Cobas e411, Germany). Statistical correlation was calculated between the ovarian cyst size and CA-125 levels using Spearman’s Rho coefficient. Results Mean age group of subjects were 29.7 ± 7.3 years and mean value of CA-125 (normal < 35 IU/mL) was found to be increased: 118.0 ± 147.1 IU/mL so was the mean diameter of cysts (cut off ≤ 5 cm): 48.6 ± 59.8 cm. No correlation was found between CA-125 levels and volume of ovarian cyst ( r = 0.005, p = 0.680) for all subjects. Conclusions The lack of correlation between size of ovarian cysts and CA-125 levels provides a hint that the ovarian cyst epithelium does not directly express CA-125 and it may come from sites like the fallopian tube. Thus, raised level of CA-125 in benign ovarian cyst should be followed-up more closely, demanding assessment of fallopian tubes for early diagnosis of ovarian cancer. Also, algorithms can be explored to include size of ovarian cyst and CA 125 levels to predict ovarian cancer.

It's not all about the size-characteristics and risk factors for malignancy of mucinous cystic neoplasms of the pancreas.

BackgroundMucinous cystic neoplasms (MCN) of the pancreas are rare mucin-producing cystic tumors. As they harbor malignant potential, surgical resection is frequently performed. Current guidelines recommend surgery in asymptomatic patients only for MCN exceeding 4 cm. The aim of this study was to identify radiological and clinical risk factors for malignancy in a single-center cohort of MCN.MethodsAll resected MCN from a single high-volume center between 2004 and 2019 were retrospectively analyzed. Patient characteristics, preoperative findings, histopathological results, and data on the postoperative course were recorded. Variables associated with malignancy were evaluated using χ2 and Mann-Whitney U test. Receiver operating characteristic (ROC) curves were used to model predictive capabilities of preoperative tumor marker levels. Furthermore uni- and multivariate logistic regression analysis were performed for binary variables. Survival time was plotted as Kaplan-Meier curves and evaluated by log-rank test.ResultsA total of 63 patients were included. Median age was 62 years; 51 (81.0%) of them were women; median tumor size was 3.5 cm (range, 0.5–18.5); 16 (25.4%) of tumors harbored invasive carcinoma and 13 presented intraepithelial dysplasia (20.6%); 7 (43.8%) invasive carcinomas were smaller than 4 cm. All malignant MCN were radiologically suspected of malignancy (calcifications, mural nodules, or wall thickness) preoperatively. Elevated levels of carbohydrate antigen 19-9 (CA19-9) and carcinoembryonic antigen (CEA) were strongly associated with malignancy (odd’s ratio 33.600; 7.000–161.270); P<0.001 and odd’s ratio 19.250; 3.370–109.970; P<0.001). Other factors associated with malignancy were preoperative weight loss (P=0.015) and higher age (P=0.048). Tumor size, abdominal or back pain or jaundice showed no significant correlation to malignancy in our cohort.ConclusionsMalignant potential of MCN should not be underestimated and a close clinical and radiological follow-up is mandatory in all suspected cases. This is especially important for small lesions. Risk assessment should not rely only on tumor size but consider all clinical, radiological and laboratory findings of each case. Follow-up should be performed by experienced surgeons and radiologists in high volume centers for pancreatic surgery. Surgery should be performed in all cases in which malignancy is suspected.
