ABSTRACT
OBJECTIVE@#To evaluate the diagnostic value of the serum tumor markers carcinoembryonic antigen (CEA), cytokeratin-19-fragment (CYFRA21-1), squamous cell carcinoma associated antigen (SCCAg), neuron-specificenolase (NSE) and pro-gastrin-releasing peptide (ProGRP) for lung cancers of different pathological types.@*METHODS@#This study was conducted among patients with established diagnoses of lung adenocarcinoma (LADC, n=137), lung squamous cell carcinoma (LSCC, n=82), small cell lung carcinoma (SCLC, n=59), and benign chest disease (BCD, n=102). The serum tumor markers were detected for all the patients for comparison of the positivity rates and their serum levels. ROC curve was used for analysis of the diagnostic efficacy of these tumor markers either alone or in different combinations.@*RESULTS@#In patients with LADC, the positivity rate and serum level of CEA were significantly higher than those in the other groups (P < 0.05); the patients with LSCC had the highest positivity rate and serum level of SCCAg among the 4 groups (P < 0.05). The positivity rates and serum levels of ProGRP and NSE were significantly higher in SCLC group than in the other groups (P < 0.05). CYFRA21-1 showed the highest positivity rate and serum level in LADC group and LSCC group. With the patients with BCD as control, CEA showed a diagnostic sensitivity of 62.8% and a specificity of 93.1% for LADC, and the sensitivity and specificity of SCCAg for diagnosing LSCC were 64.6% and 91.2%, respectively. CYFRA21-1 had the highest diagnostic sensitivity for LADC and LSCC. The diagnostic sensitivity and specificity of ProGRP for SCLC were 83.1% and 98.0%, respectively. When combined, CYFRA21-1 and CEA showed a high sensitivity (78.8%) and specificity (86.3%) for diagnosing LADC with an AUC of 0.891; CYFRA21-1 and SCCAg had a high sensitivity (84.1%) and specificity (87.3%) for diagnosing LSCC with an AUC of 0.912. NSE combined with ProGRP was highly sensitive (88.1%) and specific (98.0%) for diagnosis of SCLC, with an AUC of 0.952. For lung cancers of different pathological types, the combination of all the 5 tumor markers showed no significant differences in the diagnostic power from a combined detection with any two of the markers (P>0.05).@*CONCLUSION@#CEA, CYFRA21-1, SCCAg, NSE and ProGRP are all related to the pathological type of lung cancers and can be used in different combinations as useful diagnostic indicators for lung cancers.

Objective To analyze the clinical characteristics and changes of serum tumor markers in lung cancer patients with different smoking status in Hanzhong area. Methods A retrospective analysis was performed on 642 hospitalized lung cancer patients in Hanzhong area from March 2017 to March 2019. According to their smoking status, they were divided into observation group (smoking history, n=404) and control group (no smoking history, n=238). Age, sex, place of residence, basic information of the disease including pathological stage, pathological type, short-term efficacy, survival and serum tumor marker level were analyzed retrospectively. Results The proportion of male in observation group (67.08%) was significantly higher(57.56%) (χ2=5.855,P2=4.824 , P2=2.110 , P2=15.291, P 2=10.817,P2=2.051, P>0.05). The 1-year survival rate of the observation group (64.85%) was significantly lower than that of the control group (73.95%) (χ2=5.255, P<0.05). Conclusion Middle-aged and elderly male smokers in Hanzhong area have a high incidence of lung cancer, multiple stage Ⅲ squamous cell carcinoma, and the level of tumor markers in serum is higher than that of non-smokers. The prognosis is not good, so we should encourage patients to quit smoking, which can improve the survival rate of patients.
ABSTRACT
Background: Germ cell tumors are found primarily in children and young adults usually arising from gonads and rarely from extragonadal sites like mediastinum, retroperitoneum, pineal gland and sacrococcygeal region. Involvement of lymphnodes or bodycavities (pleural/peritoneal cavity) is usually associated with metastatic disease.Methods: This is a retrospective analysis of 96 cases of germ cell tumor for which a primary diagnosis of germ cell tumor was given by cytology from primary and metastatic sites. The study period is from January 1993- December 2013. Pap stained and Romanowsky stained smears and cell block sections (10cases) were studied. Serum tumor markers (LDH, BetaHCG and AFP) were correlated in all cases along with histopathology in available cases.Results: Among 96 cases 34 were diagnosed as seminoma/dysgerminoma,10 as embryonal carcinoma,9 as yolk sac tumor,6 as teratoma and 2 as mixed germ ell tumor. In 25 cases the cytology report was suggestive of germ cell tumor and in 10 cases malignant cells favouring germ cell tumor. Among the 10 cases the serum markers were high in six of the cases and the clinician after discussing with the pathologist treated them as germ cell tumors. 47 cases had histopathology and it correlated with cytology except in 14 cases which showed no residual neoplasm after chemotherapy. 15 cases expired immediately after the diagnosis or during the course of treatment 12cases were lost to follow up. Rest of the cases have completed the treatment. In our study the serum tumor markers showed a sensitivity of 92.75% and positive predictive value was 71.11%.Conclusions: The study highlights the importance of picking up the diagnosis of germ cell tumors by fine needle aspiration cytology so that patient can get an early diagnosis, effective treatment and a multidisciplinary approach is essential in diagnosing a difficult case of germ cell tumor. Previous history, radiology, clinical features and serum tumor markers all aid in the cytological diagnosis of germ cell tumor.
ABSTRACT
Objective: To investigate the effect of modified Renseng Yangrong Tang combined with chemotherapy on serum tumor markers and Th1/Th2 type cytokines expression in cervical cancer patients. Method: A total of 114 patients with cervical cancer admitted in our hospital from December 2014 to December 2017 were selected as the study subjects. According to the random number table method, the patients were divided into two groups. The control group (57 cases) was treated with conventional chemotherapy. The treatment group (57 cases) was treated with modified Renseng Yangrong Tang in addition to the conventional chemotherapy. Traditional Chinese medicine (TCM) symptom scores, serum tumor markers[carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCCA), carbohydrate antigen 125 (CA125)]and Th1/Th2 type cytokine[interferon gamma-interferon (IFN-γ), interleukin-4 (IL-4), interleukin-2 (IL-2), interleukin-6 (IL-6) levels], clinical efficacy after treatment 3 months, and adverse reaction rate of two groups were observed. Result: There was no significant difference in TCM symptom scores, serum tumor markers and Th1/Th2 cytokines between the two groups before treatment. After treatment, the TCM symptom scores, CEA, SCCA, CA125, IL-6, and IL-4 levels in the treatment group were lower than those in control group and before treatment (Pγ were higher than those in the control group and before treatment (PPχ2=4.524, 4.150, PConclusion: Modified Renseng Yangrong Tang can significantly relieve clinical symptoms, reduce the level of serum tumor markers, improve cellular immunity, improve the recent therapeutic effect, and reduce adverse reactions in patients with cervical cancer chemotherapy.
ABSTRACT
Objective:To detect the expression of six miRNAs for miR-146a,miR-224,miR-34c,miR-200a,miR-148b,miR-375 level in primary hepatocellular carcinoma patients tissues and serum,and to explore the correlation between the expression of miRNA and inflammatory factors,in the hope of verification whether circulating miRNA could be used as an ideal blood borne biomarker for early detection of primary liver cancer.Methods:Venous blood samples were collected from patients with primary liver cancer,hepatitis,cirrhosis and healthy controls,cancer tissues and para cancerous tissues were collected from patients with cancer.After the total RNA was extracted,the relative expression levels of miRNA were detected by real-time quantitative PCR,and the relationship between the expression level of miRNA and the expression of serum tumor markers AFP,CEA,CA19-9 and CA125 was detected.The correlation between the expression level of miRNAs and the expression of HBsAg,anti-HBs,HBeAg,anti-HBe,anti-HBc and inflammatory factors IL-12,IL-4,IL-6,IL-10,IFN-γ,TNF-α was detected as well.Results:Compared with the healthy group,the expression of miR-34c,miR-224 and miR-146a in serum and tissues of PHC group was significantly up-regulated,and the expression of miR-200a,miR-148b and miR-375 in serum and tissues of PHC group was significantly down regulated.The difference was statistically significant.There was a regression relationship between HBsAg and serum miR-375 and miR-146a,and miR-375 decreased with the increase of HBsAg expression,while miR-146a increased with the increase of HBsAg.There was a regression relationship between IFN-γ and miR-146a,miR-146a increased with the decrease of IFN-γ expression.The diagnostic ability of miR-375 and miR-146a was greater than that of CA19-9 and AFP.Conclusion:MiR-146a,miR-224,miR-34c,miR-200a,miR-148b,miR-375 in serum and tissue of primary hepatocellular carcinoma are differentially express,among them,the diagnostic ability of miR-375 and miR-146a is better than that of AFP and CA19-9,and serum miR-375 and miR-146a may be the new markers for early diagnosis of PHC.
ABSTRACT
Objective To explore the value of combined detection of serum tumor markers in the diagnosis of lung cancer.Meth-ods Electrochemiluminescence immunoassay was used to detect 5 kinds of tumor markers in 86 patients with lung cancer,92 pa-tients with benign lung disease and healthy persons,serum levels of neuron specific enolase(NSE),carcinoembryonic antigen (CEA),squamous cell carcinoma antigen(SCCAg),carbohydrate antigen 125(CA125)and cytokeratin fragment 21-1(CYFRA21-1).The difference of tumor markers in different patients and different pathological types of lung cancer and the difference of single and combined detection of tumor markers in the diagnosis of lung cancer were compared.Results The serum levels of NSE,CEA, SCC,CA125 and CYFRA211 in patients with lung cancer were significantly higher than those in benign lung disease group and healthy control group,and the difference was statistically significant(P<0.05).The average level of NSE in the serum of patients with small cell lung cancer was higher,CEA,CA125 levels in the serum of patients with adenocarcinoma was higher,and the levels of SCC and CYFRA211 in the sera of patients with squamous cell carcinoma were higher.The combined detection of serum tumor markers is more sensitive than that of the single detection,and the combined detection of NCE,CEA and CYFRA211 has relatively high specificity and accuracy.The combined detection of 5 serum indexes has the highest sensitivity,but its specificity is low,only 81.53%.Conclusion The single tumor marker has certain limitation whose sensitivity and specificity have great differences for dif-ferential diagnosis of different pathological types of lung cancer,and combined detection of the serum tumor markers can be mutual-ly complementary,which could have high sensitivity and accuracy.
ABSTRACT
Objective To explore the dynamic changes of serum HMGB1, CEA and SCC as well as the value in the evaluation of prognosis of patients with esophageal squamous cell carcinoma resection. Methods The dynamic changes in serum levels of HMGB1, CEA and SCC were measured respectively in 100 patients preopera-tively as well as a month after esophagectomy. The relationships between the changes of serum tumor markers and the clinical efficacy were analyzed. Results The 5-years survival rate of the CEA, SCC and HMGB1 negative peo-ple before operation was significantly higher than that of the positive patients (P < 0.05). The 5-years survival rate of those patients with all three markers negative before operation was significantly higher than that of those patients with the three markers positive (P < 0.01). The Median Survive Time of the patients with the levels of all three markers decreased after operation was longer than those with the levels of all the three markers increased (χ2 =6.584, P=0.01). The Median Survive Time of the patients with levels of the three markers decreased by more than 50%was longer than those with the levels decreased by less than 50% (χ2=5.418, P = 0.02). Conclusions The dynamic and combined detections of serum HMGB1, CEA, SCC in patients with esophageal squamous cell carcino-ma resection can effectively evaluate the therapeutic effect and prognosis.

ABSTRACT
Through its high affinity with membrane receptors, growth factors promote tumor growth, metastasis and an-giogenesis, induce the change of tumor microenvironment and regulate immune response. It has been demonstrated that the serum protein levels of epidermal growth factor and its receptor, transforming growth factors and their receptors, insu-lin-like growth factors, and angiogenesis factors may have predictive value for metastasis and prognosis of breast cancer. Detecting serum levels of growth factors and their receptors which have synergistic effect or interaction with each other may be helpful for predicting the metastasis and progression of breast cancer.
