Combined Determination of Serum PG and CEA and its Clinical Application in Distinctive Diagnosis of Benign and Malignant Gastric Ulcer / 中国基层医药

Objective The aim of this study was to evaluate the clinical value and the possibilities of measuring the serum levels of pepsinogen I (PG I ) and careineembryonic antigen (CEA) in 402 patients with gastric ulcer.Methods The patients with gastric ulcer were all confirmed by either operation or gastrofiberscope,and divided into two groups,benign and malignant gastric ulcer.After comparing the relationship between the patients'clinical appearance and the Radioimmunoaasay(RIA) results,(CEA and PG I ).Results There were 73 patients were onfirmed malignant gastric ulee in 402 patients.The positive rate of PG was 52.05% (38/73).The positive rate of CEA was 64.38% (47/73).Both were 30.14% (22/73).Then there were 63(63/73) patients who was positive in the combined determination.Solo determination's positive rate of CEA and PG were significantly different from the combined determination.(P＜0.05 and 0.01) Conclusions Feasibility and the necessity of combined determination were evaluated.Compared with solo determination,for patients with malignant gastric ulcer,it was more sensitive to determine and analysis the serum levels of PG I and CEA sYnthetically.So it is recommended to popularize the combined determination of serum PG I and CEA in clinical distinctive diagnosis of benign and malignant gastric ulcer.

Clinical significance of serum CP2, CA125, salicylic acid and carcinoembryonic antigen in endometrial carcinoma / 中华妇产科杂志

Objective To explore the clinical significance of CP2,CA125,salicylic acid(SA)and carcinoembryonic antigen(CEA)in endometrial carcinoma patients. Methods A retrospective study was carried out on 154 cases of endometrial carcinoma with tumor markers test results who were admitted to our department from Aug 1992 to Nov 2004.Results The patients were followed up for(38±28)months.23.4%,36.8%,19.0%and 30.3%of cases were with abnormal values of CP2,SA,CA125 and CEA.CP2 abnormal level was related with the stage,cell differentiation,adnexa metastasis,positive peritoneal cytology and pelvic lymph node metastasis(P=0.002,P=0.040,P=0.019,P=0.019,P:0.005).SA abnormal level was related with the adnexa metastasis and positive peritoneal eytology(P=0.021,P=0.000). CA125 abnormal level was related with the cell differentiation,cervical metastasis and pelvic lymph node metastasis(P=0.014,P=0.006,P=0.018).The survival was related with CP2,CA125 and CEA (P=0.016,P=0.000,P=0.016),especially CA125. Conclusions Among the commonly used tumor markers,CP2 is related with many clinical pathological parameters.CA125 elevation may strongly suggest worse prognosis.
