ABSTRACT

Objective To investigate the value of detecting peripheral blood epidermal growth factor receptor (EGFR) gene in predicting the therapeutic efficacy of advanced non-small cell lung cancer. Methods A total of 150 patients with stage ⅢA-Ⅳ non-small cell lung cancer diagnosed in Shanxi Provincial Cancer Hospital from October 2013 to February 2015 were collected. The peripheral blood EGFR gene was detected by amplification refractory mutation system (ARMS). The relationship between the mutation rate and the clinicopathological features of patients was observed, and 80 patients were selected into the follow-up treatment according to the inclusion criteria. Forty patients (all 19 or 21 exon mutations) in group A with EGFR gene mutation were treated with gefitinib orally. Forty patients with wild type EGFR gene in group B underwent 4 cycles of NP regimen. Efficacy and progression-free survival were evaluated in both groups. Results The mutation rate of EGFR gene was 33.3 % (50 cases), of which 29 were exon 19, 18 were exon 21 and 3 were exon 18 and 20. The mutation rate of EGFR gene was higher in female, adenocarcinoma and non-smoker (all P<0.05). Among the 80 patients who received follow-up treatment, the effective rate [67.5%(27/40) vs. 32.5 % (13/40)] and disease control rate [85.0 % (34/40) vs. 65.0 % (26/40)] in group A were significantly higher than those in group B, and the median PFS was prolonged (9.00 months vs. 4.25 months),the differences were statistically significant (χ2=9.800, P=0.002;χ2=4.267, P=0.039;χ2= 15.792, P<0.001). Conclusion The detection of peripheral blood EGFR mutation can be used to predict the efficacy of tyrosine kinase inhibitors in non-small cell lung cancer.

ABSTRACT

Objective To investigate the value of magnetic resonance diffusion-weighted imaging (DWI) in combination with peripheral serum tumor markers in the diagnosis and therapeutic evaluation of small cell lung cancer (SCLC) brain metastases.Methods Retrospective analysis of 368 SCLC cases diagnosed by histopathology or cytology from February 2009 to February 2012 in Shanxi Provincial Cancer Hospital was made.All patients underwent pathological examination of progastrin-releasing peptide (ProGRP),neuron-specific enolase (NSE) and brain DWI,and measured the apparent diffusion coefficient (ADC) of DWI sequences of brain metastases.The difference between the positive rates of ProGRP and NSE in patients with or without brain metastases was compared by the X2 test,and the diagnostic efficiency of ProGRP,NSE,DWI and combined detection for brain metastases were analyzed.The Kruskal-Wallis H test was used to compare the changes of ADC value,ProGRP and NSE before and after brain irradiation therapy in brain metastases of SCLC.Pearson correlation analysis was made to evaluate the correlation between the changes of ADC value and the levels of ProGRP and NSE in SCLC patients with brain metastases before and after treatment.Results The median expression of serum ProGRP in 169 SCLC patients was 2 664.7 pg/ml (98.4-4 876.8 pg/ml),with a positive rate of 98.2 % (166/169).The median expression of NSE was 41.9 μg/L (9.4-264.3 μg/L),with a positive rate of 70.4 % (119/169).The median expression of serum ProGRP level was 514.3 pg/ml (3.9-2 899.3 pg/ml) in 199 SCLC patients without brain metastasis,the positive rate was 89.4 % (178/199).The median expression of NSE was 40.4 μg/L (0.3-176.1 μ,g/L),with a positive rate of 64.8 % (129/199).The difference of ProGRP level between the two groups was statistically significant (u =121.47,P < 0.001),but there was no significant difference in NSE level (u =1.35,P =0.12).The sensitivities of ProGRP,NSE,DWI,ProGRP+DWI and NSE+DWI were 68.4 %,41.2 %,66.7 %,92.2 %,and 82.4 %,and the specificities were 52.9 %,35.3 %,76.5 %,94.1%,and 88.2 %.The sensitivity and specificity of ProGRP+DWI and NSE+DWI were higher than those of single test,and the differences were statistically significant (all P < 0.001).One hundred and fifty-six SCLC patients with brain metastases were treated with whole brain radiotherapy.Pearson correlation analysis showed that ADC values were negatively correlated with ProGRP and NSE levels (r =-0.945,P < 0.001;r =-0.995,P < 0.001).Conclusion DWI combined with ProGRP and NSE can provide objective evidence and clinical guidance for the diagnosis of SCLC brain metastases and the evaluation of whole brain radiotherapy.

ABSTRACT

Objective To understand the status and influencing factors of thyroid disease in breast cancer patients, and to identify the high-risk people with thyroid disease. Methods Breast cancer patients were continually collected from Jan 2016 to Mar 2016 in Shanxi Cancer Hospital. Age, surgery time, the state of thyroid disease, medical record, the general condition, immunohistochemistry and pathological findings, thyroid B-mode ultrasonography were investigated respectively. All cases were divided into two groups according to whether to suffer from thyroid disease or not. The influencing factors for thyroid disease in patients with breast cancer were screened. Logistic regression was used for univariate and multivariate analysis. Results A total of 293 cases (69.3 %) suffered from thyroid disease in 423 breast cancer patients. The univariate analysis showed that prevalence rate of thyroid disease had statistical differences in age [<50 years old:49.5%(145/293) vs. 76.1%(99/130); ≥50 years old:50.5%(148/293) vs. 23.9%(31/130);χ2=24.297, P<0.001], body mass index [18.5-23.9 kg/m2:41.0%(120/293) vs. 52.3%(68/130);24.0-27.9 kg/m2:45.4%(133/293) vs. 40.8 % (53/130); ≥28.0 kg/m2: 13.7 % (40/293) vs. 6.9 % (9/130); χ2= 6.395, P=0.041], menopausal state [not: 59.7%(175/293) vs. 77.7%(101/130); yes: 40.3%(118/293) vs. 22.3%(29/130);χ2=12.443, P<0.001], estrogen receptor (ER) [ER--ER+: 44.0%(129/293) vs. 56.9%(74/130);ER++ - ER+++: 56.0 % (164/293) vs. 43.1 % (56/130); χ2 = 5.951, P= 0.015]. There were no significant differences in the times of pregnancy and production, history of abortion, progesterone receptor (PR), human epidermal growth factor receptor-2 (HER-2), triple negative breast cancer, T stage, N stage, histological grade and TNM stage (P> 0.05). Multivariate analysis showed that the risk factors were age (OR= 3.928, 95 %CI=1.819-8.482, P<0.001) and ER++-ER+++(OR= 1.696, 95 %CI= 1.094-2.628, P= 0.018). Conclusion Age≥50 and ER++-ER+++are the major influencing factors of thyroid disease for patients with breast cancer.

ABSTRACT

Objective To investigate the expression of insulin-like growth factor 1 (IGF-1), insulin growth factor receptor 1(IGF-1R)and insulin growth factor receptor 2(IGF-2R)in colorectal cancer, and their relationship with the relevant clinicopathological factors. Methods Immunohistochemical SP method was used to detect the expression of IGF-1,IGF-1R and IGF-2R in 154 cases of colorectal cancer tissues,58 cases of benign disease tissues (colorectal adenoma, polyps) and 90 normal tissues. Results The positive rate of IGF-1 and IGF-1R expression in colorectal cancer tissues [93.5%(144/154), 70.1%(108/154)] was higher than that in benign diseases [51.7%(30/58), 51.7%(30/58)] and adjacent normal tissues [18.9%(17/90), 35.6%(32/90)] (P=0.001). The positive expression rate of IGF-1 and IGF-1R in colorectal cancer tissue, benign disease tissue and adjacent normal tissues decreased gradually, and there was significant difference between any two groups (P<0.05). The positive expression rate of IGF-2R had no significant difference between any two groups (P>0.05). IGF-2R was significantly different between any two groups (P<0.05). The expression of IGF-1R and IGF-2R in colorectal cancer tissues were not significantly correlated with gender, location, tumor size, family history, depth of tumor invasion and local lymph node metastasis (all P>0.05).IGF-1 was positively correlated with the body mass index(r=0.169,P=0.036).IGF-2R was negatively correlated with age (r=-0.196, P=0.015), and positively correlated with TNM staging in patients with colorectal cancer (r=0.227, P=0.005). The expression of IGF-1 was positively correlated with IGF-1R (r=0.281, P=0.000 1). There was no significant correlation between IGF-1 and IGF-2R in cancer tissues (P>0.05). Conclusion IGF-1 and IGF-1R may promote the occurrence of colorectal cancer, and IGF-2R may be associated with the progress of colorectal cancer,and obesity is a risk factor for incidence of colorectal cancer.

ABSTRACT

Objective To investigate the application value of human papillomavirus (HPV) combined with thinprep cytology test (TCT) detection in screening of cervical cancer. Methods 276 patients were enrolled to have HPV and TCT tests at Department of Gynecology, Shanxi Cancer Hospital from January to December in 2014. Pathological examine was applied to the patients with abnormal results of HPV and TCT. The diagnostic value of HPV, TCT and their combinations was evaluated by the diagnostic sensitivity and the rate of coincidence with the pathological examine results. Results The sensitivity of HPV and its coincidence with the pathological examine results were 81.52 % (225/276) and 79.56 % (179/225), respectively, while those of TCT were 87.68%(242/276) and 76.86%(186/242), respectively. The coincidence rate between the combination method and the pathological examination was higher (94.71%, 197/208) than the individual test. Conclusion HPV combined with TCT detection can reduce the misdiagnosis rate and improve the diagnostic accuracy rate, indicating that this method is of great value in the cervical cancer screening.

ABSTRACT

Objective To explore the clinical significance of combination detection of serum squamous cell carcinoma antigen (SCC-Ag) and carcino-embryonic antigen (CEA) for the diagnosis,effect evaluation,monitoring and prognosis in cervical carcinoma.Methods Four hundred and twenty-four cases of cervical carcinoma patients diagnosed by pathology and 400 binign gynaecology patients were selected to detect levels of SCC-Ag and CEA by ELISA.Besides,the pelvic color ultrasound results of cervical carcinoma patients were collected and analyzed.Results The positive rates of serum SCC-Ag,CEA and combined detection of cervical carcinoma patients were 55.9 %(237/424),26.4 %(112/424),61.8 %(262/424),which were higher than those of binign gynaecology patients [12.0 %(48/400),12.5 %(50/400),14.5 %(58/400)],and the differences were statistical significance (all P< 0.05).The sensitivity of combined detection of SCC-Ag and CEA for diagnosing cervical carcinoma (61.8 %) was better than that of detection of alone SCC-Ag or CEA (55.9 %,26.4 %),and the difference was statistical significance (P < 0.05).The differences of pretreatment serum SCC-Ag and CEA levels in the cervical carcinoma patients who were dependent on clinical stage,pathological type,depth of invasion,lymph node metastasis were statistically significant (all P < 0.05).The combined detection of SCC-Ag and CEA in patients with stage Ⅰ and Ⅱ had higher positive rates [45.5 % (71/156),73.2 %(139/190)] than those of the ultrasound examination [33.3 %(52/156),51.1%(97/150)] (P< 0.05).After surgery or concurrent chemoradiotherapy or surgery combined radiation and chemotherapy,SCCAg levels of patients in post-treatment (median 0.34,0.51,0.33 ng/ml) were much lower than those of pretreatment (median 0.48,3.44,1.29 ng/ml),and CEA levels of post-treatment (median 0.75,0.81,0.71 ng/ml)were also lower than those of pre-treatment (median 1.22,1.53,1.50 ng/ml) (P < 0.05).After treatment,cervical cancer patients with the raised or not decreased to the normal range levels of SCC-Ag and CEA had recurrences or metastasis rates of 33.3 %(6/18),56.5 %(13/23) and 46.1%(35/76).Survival rate of the patients with positive SCC-Ag was significantly lower than that of patients with negative (P < 0.05),while the survival rate of patients with positive or negative CEA had no difference (P > 0.05).Conclusions Combined detection of SCC-Ag and CEA can be used as an important indicator to estimate clinical stage,pathological type,depth of invasion,lymph node metastasis,curative effect and prognosis of cervical carcinoma.Combined detection of SCC-Ag and CEA had higher positive rates than pelvic color ultrasound examination for cervical carcinoma patients in stage Ⅰ and Ⅱ.

ABSTRACT

Objective Toevaluatethediagnosticvalueofhumanepididymisprotein4(HE4)andcar-bohydrate antigen 1 25 (CA1 25 )for distinguishing between benign and malignant ovarian neoplasms.Methods 1 1 09 patients with ovarian neoplasms were enrolled in this study,serum concentration of HE4 and CA1 25 was assayed using ELISA technique.And the markers were evaluated for significance separately and in combination. Results 1SerumlevelsofHE4andCA125weresignificantlyhigherinpost-menopausalwomenthanthosein pre-menopausal women(t=8.40,P<0.05;t=7.02,P<0.05).In addition,the more children the patients born,the higher serum levels of these two markers were(F=1 5.36,P<0.05;F=1 3.00,P<0.05).2 Serum HE4 levels were significantly higher in the ovarian cancer patients compared with those seen in patients with benign or borderline tumor(t=1 3.68,P<0.05;t=1 4.94,P<0.05).Serum CA1 25 levels were significantly higher in the ovarian cancer patients compared with those seen in patients with benign or borderline tumor(t=1 4.1 6,P<0.05;t=1 7.27,P<0.05).Morever,it also appared in the ovarian cancer patients with ascites and vascular embolism.Morever,the levels of HE4 were significantly higher in the ovarian cancer with ascites and vascular embolism than without it(t=7.08,P<0.05;t=4.41,P<0.05),the levels of CA125 were signifi-cantly higher in the ovarian cancer with ascites and vascular embolism than without it(t=9.67,P<0.05;t=4.75,P<0.05).3 During follow-up,serum HE4 and CA1 25 levels significantly decreased at 3 months after operation(t=9.86,P<0.05;t=5.12,P<0.05).4 Receiver operating characteristic curve,ROC)analysis revealed that no difference was observed in AUC values for HE4,CA1 25 and risk of ovarian malignancy algo-rithm(ROMA).5 Compared to CA1 25 ,HE4 had significantly higher specificity and lower sensitivity.Howev-er,sensitivity were increased when the two markers were combined with each other.However,the sensitivity of combination with two markers was higher than single detection and ROMA,but the specificity was lower in com-bination with two markers than single detection and ROMA.If we divide the ROMA by a woman′s menopausal status,ROMA has a higher sensitivity (73.84%,84.1 9%) and lower specificity (66.06%,66.67%). Conclusions ThelevelsofCA125hasahighsensitivity,andthelevelsofHE4isahighspecificity.CA125 combined with HE4 can provide a more sensitivity and accurate predictor of ovarian cancer than either alone.

ABSTRACT

Objective The purpose of this study was to discuss the clinical significance of serum levels of Pro-gastrin-releasing peptide (ProGRP) in diagnosis,therapy monitoring and prognosis in patients with small cell lung cancer (SCLC).Methods Clinical diagnostic trial.Serum levels of ProGRP were measured by ELISA assays in 413 SCLC patients,418 NSCLC,120 with benign pulmonary diseases patients and 200 healthy subjects.Patients were recuited by the Shanxi Cancer Hospital from Dec.2005 to Oct.2008.Three hundreds and sixty-eight patients with SCLC were followed up from Dec.2005 to Oct.2011.The receiver operating characteristic curves (ROC) was used to set the cut-off value of ProGRP and the area under ROC (ROC-AUC).The sensitivity and specificity of ProGRP were analyzed for diagnosing SCLC.The survival analysis was performed by the Kaplan-Meier method and Cox's proportional hazards model for multivariate analysis of prognosis.Results Using healthy subjects group as control,the largest Youden index point of ROC was used to set the cut-off values of ProGRP and NSE (45.3 ng/L and 12.4 ng/L).The ROC-AUC of ProGRP was 0.798 (95% CI:0.746-0.850)the sensitivity and specificity were 79.2%,98.1% respectively.The AUC of NSE was 0.786(95% CI:0.726-0.746),the sensitivity and specificity were 71.9%,96.7% respectively; Combing detection of ProGRP and NSE,the sensitivity and specificity were 88.1%,95.8% respectively.Serum levels of ProGRP in healthy subjects,benign pulmonary diseases,NSCLC and SCLC groups were 6.9 (5.3-8.6),36.8 (26.3-43.4),21.3 (18.6-35.2) and 1758.7 (368.4-2967.3) μg/L respectively.The serum levels of ProGRP in SCLC groups were significantly higher than those in the healthy group,benign pulmonary diseases group and NSCLC group (H =103.66,P =0.000).Serum levels of ProGRP in SCLC at stage Ⅰ-],stage m,stage Ⅳ were 543.3 (256.8-843.2),1440.6 (1042.4-2543.3) and 1897.6 (1586.5-3958.7) μg/L,respectively (H =25.974,P =0.000).Serum levels of ProGRP in 165 SCLC patients with complete remission(CR) were significantly declined after treatment (U =11.65,P < 0.01).The levels of ProGRP in 146 SCLC patients with partial remission(PR) slowly decreased (U =9.17,P < 0.01).Thirty-nine cases with progressive disease (PD)and 63 cases with stable disease(SD) presented elevated ProGRP levels (U =3.314,P < 0.001 ; U =2.54,P < 0.01,respectively).By the end of October 31st 2011,a total of 368 cases with SCLC were followedup.Ratio of follow-up was 89.1%.There were 56 deaths in 119 SCLC patients with ProGRP < 1000 μg/L (median time =16.0 months,4-23 months) ; 159 deaths in 249 with ProGRP > 1000 μg/L (median survival time =12.0 months,2-18 months).Median survival time of the two groups showed significant differences(x2 =11.04,P =0.001).Multivariate analysis by Cox's proportional hazards model revealed that ProGRP was independent prognostic factor related to the overall survival (OS) of SCLC patients.Conclusions The serum ProGRP is valuable tumor marker for diagnosis,treat monitoring and prognosis of SCLC.It's important to predict relapses and recurrence of diseases earlier,instruct therapy and prognosis assessment.
