Comparison of clinical utility of Cancer Ratio, CEA, Malignant Cytology in diagnosis of suspected malignant pleural effusion

Introduction: Pleural effusion is one of the manifestation of a malignant disease which may be malignant pleural effusion with demonstrable malignant cells in the fluid or para-malignant pleural effusion which is reactive response or due obstruction of lymphatic drainage rather than invasion of pleural cavity. Various modalities are there to investigate this condition including routine microscopy, cytology, biopsy etc. Objective: To understand and compare the utility of cancer ratio, tumor markers, malignant cytology in cases of suspected malignant pleural effusion. Material and Methods: This Case Control Cross sectional study was conducted among patients attending respiratory OPD at Sir Sunder Lal Hospital, BHU, Varanasi, diagnosed with malignant pleural effusion and non-malignant pleural effusion. Results: Significant association was found between Cancer Ratio-Carcinoembryonic Antigen, CEA (p = 0.0069), CEA-Cytology (p = <0.01801)

Carcinoembryonic antigen (CEA) and other surrogate inflammatory biomarkers in COVID-19

It has been two years since the global outbreak of the highly contagious and deadly corona virus disease (COVID-19) caused by SARS-CoV-2 first emerged in China. Since then, various diagnostic, prognostic and treatment strategies undertaken to address the pandemic have been dynamically evolving. Predictive and prognostic role of various biomarkers in COVID-19 has been a subject of intense exploration. We aimed to determine the association of Carcinoembryonic antigen (CEA) and various surrogate inflammatory biomarkers with the severity of COVID-19 disease. This retrospective cohort study was carried out on 98 patients admitted in Jaypee Hospital, Noida with COVID-19 disease. Information regarding demographics, laboratory parameters and clinical history was collected from Hospital Information System. Serum levels of CEA and other biomarkers such as Neutrophil-lymphocyte ratio (NLR), C-reactive protein (CRP), Interleukin-6 (IL-6), Ferritin, and Procalcitonin (PCT) were assessed. Correlation analyses were performed between the parameters and acute respiratory distress syndrome (ARDS) stages. Logistic regression and ROC curve analysis were performed to assess the various parameters for distinguishing COVID-19 patients requiring ICU admission. Mean hospital stay, NLR, CEA, IL-6, CRP, Ferritin (P< 0.0001) and PCT (P =0.01) were significantly higher in ICU patients when compared to general ward patients. NLR, median serum CEA, IL-6, and CRP levels were significantly higher in non-survivor compared to the survivors (P< 0.0001, 0.0341 and 0.0092). CEA correlated well with disease severity based upon ARDS classification and was a better marker to differentiate patient according to ARDS stages (ARDS 0 vs 2 P= 0.0006; 0 vs 3 P< 0.0001; ARDS 1 vs 2 P= 0.0183; 1 vs 3 P=0.0006). The area under the Receiver operating characteristic (ROC) curve for CEA was 0.7467 (95% CI- 0.64885- 0.84459) which revealed the potential of CEA as a biomarker to distinguish COVID-19 patients requiring ICU admission. CEA can be used to predict the severity of COVID-19 associated ARDS as well as patients requiring ICU admission. Along with routine inflammatory biomarkers (NLR, CRP, IL-6, PCT, and ferritin), CEA should be used for early identification of critical COVID-19 positive patients and for assessing prognosis.

Diagnostic Value of cfDNA in Pancreatic Cancer / 肿瘤防治研究

Objective To explore the diagnostic value of cfDNA in pancreatic cancer. Methods A total of 467 patients with pancreatic cancer and 129 healthy controls were enrolled. cfDNA concentration was detected using the QuantiDNA Direct cfDNA Test (DiaCarta) kit. Mann-Whitney U test was used to compare cfDNA concentration between different groups, and Chi-square test was used to analyze the relationship between cfDNA and pathological data of pancreatic cancer. Diagnostic efficacy was evaluated by ROC analysis. Results The cfDNA level of patients with pancreatic cancer was significantly higher than that of healthy controls (20.85 vs. 15.15 ng/ml, P=0.0027). The positive rate of cfDNA in pancreatic cancer was higher than that in healthy controls (77.73% vs. 59.68%). The sensitivity levels of cfDNA, CEA, and CA19-9 as diagnostic markers were 62.65%, 64.04%, and 60.32%, and their specificity levels were 61.05%, 70.53%, and 87.37%, respectively. The sensitivity and specificity of the combined detection were 77.26% and 53.58% respectively. The areas under the curve of cfDNA, CEA, CA199, and combined detection were 0.62, 0.67, 0.74, and 0.67, respectively. Conclusion cfDNA is elevated in patients with pancreatic cancer and may serve as an effective marker for its diagnosis.

Clinical Value of Platelet and Its Parameters Combined with Tumor Markers in Preoperative Differentiation of Hepatocellular Carcinoma and Intrahepatic Cholangiocarcinoma / 肿瘤防治研究

Objective To evaluate the value of PLT and its parameters combined with AFP, CA199, CA125 and CEA on the preoperative differential diagnosis of hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC). Methods We analyzed retrospectively 274 patients with liver cancer who underwent surgery in the Second Hospital of Lanzhou University. They were divided into 229 cases in HCC group and 45 cases in ICC group according to postoperative pathological results. The differences of PLT, its parameters and tumor markers between the two groups were compared. ROC curve was used to evaluate the differential diagnosis effect on HCC and ICC by significantly different indicators in single and combined forms. The best scheme was verified in the patients with determined and undetermined preoperative diagnosis. Results Compared with HCC group, the levels of PLT, PCT, CA199 and CA125 in ICC group were higher (P < 0.05) and the level of AFP was lower (P < 0.05). The diagnostic analysis results of ROC curve showed that in single test, the AUC of AFP for HCC diagnosis was the largest (0.827). The AUC of the combined groups was higher than the single groups of tumor markers; the AUC of the PCT+AFP+CA199+CA125 group was the highest in all combination groups, and AUC was 0.891. The verification of the best combination group showed that the AUC was 0.924 in the preoperative determined diagnosis group and 0.854 in the undetermined diagnosis group. Conclusion Tumor markers in combination with PLT and PCT can increase the preoperative differential diagnosis efficacy of HCC and ICC. The combination of PCT, AFP, CA199 and CA125 before operation is helpful to further determine the diagnosis and plan the operation scheme.

Methods A total of 2 268 healthy people aged 45 ~ 60 years old living in Chengdu area from May 2019 to August 2020 were selected. Levels of serum tumor markers CA-724, CA-153, CA-125, CA-199 and CEA were detected by electrochemiluminescence. Positive rates of different tumor markers and confirmed diagnosis of malignant tumors were statistically analyzed. People with positive and negative tumor markers were respectively included in the positive group and the negative group, and their serum tumor markers were compared. The screening results of tumor markers in the health examination population of different gender and age, and the diagnostic efficiency of each tumor marker for malignant tumors were analyzed. Results Among the 2 268 healthy people, the positive rates of CA-724, CA-153, CA-125, CA-199 and CEA were 10.05%, 4.98%, 1.10%, 7.01% and 4.76%, respectively. A total of 72 cases were positive for tumor marker detection, with a total positive rate of 3.17% (72/2,268). Among them, 12 cases were diagnosed as early or mid-term tumors by pathology, imaging and other examinations, with a total tumor detection rate of 0.53% (12/2,268), including 8 cases of malignant tumors, with a detection rate of 0.35% (8/2,268). The levels of CA-724, CA-153, CA-125, CA-199 and CEA in the tumor markers positive group were higher than those in the negative group (P<0.05). The CA-125 and CA-199 positive rates in males were lower than those in females, while CEA positive rate was higher in males than in females (P<0.05). Positive rates of CA-153, CA-199 and CEA in different age groups showed statistically significant differences (P<0.05). Positive expression of CA-153 and CA-199 mainly occurred in the 51~60 years old group, and positive expression of CEA mainly occurred in the 45~50 years old group. ROC curve analysis showed that combined detection of CA-724, CA-153, CA-125, CA-199 and CEA had the highest sensitivity, specificity and accuracy in predicting malignant tumors, and the area under the curve was the largest (0.865). Conclusion Tumor markers CA-724, CA-153, CA-125, CA-199 and CEA are highly expressed in the 45 ~ 60-year-old health examination population in Chengdu area, and positive rate of CA-724 is the highest. Levels of tumor markers in people of different gender and age are also different. Joint detection of various tumor markers is conducive to early detection and treatment of the disease, and reduction of deterioration risk.

Gold nanorods-mediated efficient synergistic immunotherapy for detection and inhibition of postoperative tumor recurrence

Tumor recurrence after surgery is the main cause of treatment failure. However, the initial stage of recurrence is not easy to detect, and it is difficult to cure in the late stage. In order to improve the life quality of postoperative patients, an efficient synergistic immunotherapy was developed to achieve early diagnosis and treatment of post-surgical tumor recurrence, simultaneously. In this paper, two kinds of theranostic agents based on gold nanorods (AuNRs) platform were prepared. AuNRs and quantum dots (QDs) in one agent was used for the detection of carcinoembryonic antigen (CEA), using fluorescence resonance energy transfer (FRET) technology to indicate the occurrence of

Utility of triple tumor markers CA19-9, CA125 and CEA in predicting advanced stage of carcinoma gallbladder: a retrospective study

Background: A combination of serum tumor markers are used in the evaluation and prognosis of carcinoma gallbladder (GBC). Aim of the study was to find the significance of combined use of CA19-9, CA125 and CEA in advanced stage of GBC and to find the cut-off value of each of these tumor markers in metastatic GBC.   Methods: This was a retrospective observational cohort study over 1 year, which was carried out in 42 cases of advanced GBC. The patients were grouped in to locally advanced and metastatic stage on the basis of CECT scan findings. CA19-9, CA125 and CEA were assayed in all patients. These tumor markers were analysed with these two groups of GBCs. Statistical analysis was performed using R statistical software v3.6.2.Results: Out of 42 cases CA19-9 was elevated in 18 (78%), CA125 in 16 (70%) and CEA in 9 (39%) patients with metastatic disease.

Results from multivariate logistic regression analysis showed that the positive levels of CEA and CA19-9 were risk factors in the TNM staging of colorectal cancer. The ORs and 95%CI were 1.790 (1.163-2.755)and 3.476(1.790-6.749), respectively. Conclusion The positive serum concentrations of CEA and CA19-9 showed significant associations with TNM staging. Preoperative serum concentrations of CEA and CA 19-9 could be auxiliary diagnostic indicators to assess the condition of colorectal cancer.

Expression of HOPX in cervical cancer tissues and blood serum and its correlation to CEAand CA125 / 中国肿瘤生物治疗杂志

@# Objective: To investigate the expression of HOPX gene in cervical cancer tissues and blood serum as well as its effect on cervical cancer HeLa cells, and to analyze its correlation to tumor maker CEAand CA125. Methods: 50 pairs of cervical cancer tissues and para-cancerous tissues as well as the peripheral blood samples from patients with cervical cancer, who were treated at Tianjin Binhai People’s Hospital and Tianjin Wuqing People’s Hospital from June 2015 to December 2017, were collected for this study; in addition, 50 samples of blood serum from healthy people were used as control. Real-time quantitative PCR (qRT-PCR) and immumohistochemical staining (IHC) were used to detect mRNA and protein expressions of HOPX in tissue and serum samples, NCBI-GEO data base and TCGA data base were used to collect the information on HOPX gene and patients’prognosis, and the correlation between HOPX expression and patients’prognosis was analyzed. Vectors over-expressing HOPX or control vectors were transfected into HeLa cells; MTT assay and colony formation assay were used to examine the proliferation ability of HeLa cells, Tranwell assay was used to detect the migration and invasion of HeLa cells, and Western blotting was used to detect the expression of EMT-related proteins. Results: Both sample examination and data base information showed that the expression level of HOPX was down-regulated in tissue and serum samples of cervical cancer patients and was positively related with the survival of patients (r=0.736， P<0.05); while it’s expression was negatively related to the level of CEAand CA125 in cervical cancer tissues and serum (r=-0.678, P<0.05). HOPX over-expression inhibited cell proliferation, migration and invasion, promoted the expression of E-cadherin but inhibited the expression of Vimentin and ICAM1 (all P<0.05 or P<0.001). Conclusion: HOPX is low expressed in cervical cancer tissues and blood samples, and negatively correlated with CEA and CA125, but positively correlated with the survival of patients. Thus, combination of HOPX and CEA/CA125 may improve the early diagnosis rate of cervical cancer and provide a new strategy for precision treatment of cervical cancer in future.

Preoperative serum levels of cancer antigen 125 and carcinoembryonic antigen ratio can improve differentiation between mucinous ovarian carcinoma and other epithelial ovarian carcinomas

OBJECTIVE: The main aim of this study was to evaluate cancer antigen 125 (CA125)/carcinoembryonic antigen (CEA) ratio (CCR), as a reliable marker to differentiate ovarian mucinous carcinoma from other epithelial ovarian carcinomas (EOCs), namely serous, clear cell, and endometrioid carcinomas. METHODS: Female patients suffering from different kinds of EOCs whom were subjected to elective surgery at the Gangnam Severance Hospital between January 2008 and December 2016, were included in this study. The serum levels of CA125 and CEA were assayed using commercially available kits per the manufacturer's instructions. RESULTS: The CCR in mucinous carcinoma (mean 32.1) was significantly lower than that of clear cell (mean 235.0) and endometrioid carcinoma (mean 427.0) in stage I (all P < 0.05). In stage II–IV, CCR in mucinous carcinoma (mean 37.6) was significantly lower than that of serous carcinoma (mean 148.0) (P < 0.01). The sensitivity and specificity of CCR in detecting mucinous carcinoma from other types of EOC was 75.0% and 77.5%, respectively in stage I and 100.0% and 84.4%, respectively in stage II–IV (both cut-off value < 90.7). CONCLUSION: The present results suggest that pretreatment CCR might provide higher specificity and clinically relevant information as a criterion for the differentiation between ovarian mucinous carcinoma and other types of EOC.

Porocarcinoma Ecrino / Ecrine Porocarcinoma

Resumen:El porocarcinoma ecrino es un tipo muy poco frecuente de cáncer de piel, originado en la porción epidérmica de las glándulas sudoríparas ecrinas. Representa no más del 0.01% de los tumores cutáneos. El 20% de los porocarcinomas ecrinos son recurrentes y el 20% producen metástasis a ganglios linfáticos. Se ha reportado escasos casos de metástasis a distancia. Tiene un índice de mortalidad del 67% de los pacientes con metástasis.El diagnóstico es basado en los hallazgos histopatológicos y los estudios complementarios de inmunohistoquímica, a veces necesarios para el diagnóstico diferencial con otros tipos más frecuentes de cáncer de piel.No existen pruebas de que este tipo de carcinoma responda a la quimioterapia ni la radioterapia. Se considera que el manejo principal debe ser la resección quirúrgica y la electroquimioterapia.

Abstract:Eccrine porocarcinoma is a rare type of skin cáncer arising from the intraepidermal portion of eccrine sweat glands, representing no more tan 0.01% of all cutaneous tumors. 20% of the Eccrine porocarcinoma will recur and 20% will metastasize to regional lymph nodes. Few cases of distant metastases has been reported . There is a mortality rate of 67% in patients with metastases. The diagnosis is primarily based on histopathologic findings and complementary immunohistochemistry for differential diagnosis mainly with more frequent skin cáncer.Neither chemotherapy nor radiation therapy has been proven to be of clinical benefit in treating this type of carcinoma. It is considered that the management should be based on surgical resection and electrochemotherapy.
