RESUMEN

Objective To investigate the clinical value of serum tumor makers CA15-3,19 fragments of cellular keratin antigen(CYFRA21-1)combined with the color Doppler ultrasound and mammography X-ray in diagnosis of early breast cancer.Methods According to the postoperative pathologic diagnosis,collected 106 cases of patients with breast cancer (breast cancer group) and 50 cases of patients with benign breast lesions (control group),the serum tumor makers CA15-3,CYFRA21-1,the color Doppler ultrasound and mammography X-ray were compared with postoperative pathology and statistical analyzed retrospectively.Results The sensitivity of CA15-3 was 63.2%(67/106),specificity was 94.O% (47/50);the sensitivity of CYFRA21-1 was 73.6%(78/106),specificity was 88.0%(44/50);the sensitivity of color Doppler ultrasound was 77.4%(82/106),specificity was 90.0%(45/50);the sensitivity of mammography X-ray was 75.5%(80/106),specificity was 92.0%(46/50);the sensitivity of the four combined detections was 96.2%(102/106),specificity was 80.0%(40/50).The sensitivity of combined detection was higher than any of them individually,there was statistical significance (P<0.05).Conclusions Combined diagnosis is an effective way of early breast cancer detection.It has high positive rate of diagnosis and reliable guidance significance for diagnosis and treatment.

RESUMEN

Objective To study the clinicopathological characteristics of hepatobiliary cystic neoplasms(cystadenoma and cystadenocarcinoma)in order to improve its diagnostic and therapeutic accuracy.Methods A retrospective analysis was done on the clinical materials of 9 cases of cystic biliary tumors hospitalized in the People's Hospital of Rizhao City from May 1993 to May 2007.All cases were confirmed by operation and pathologic biopsy.Results Six cases were biliary cystadenoma with muhilocular cyst.The other three cases were biliary cystadenocarcinoma,two with single cyst and one with multilocular cyst.Of the three cystadenocarcinorna,two cases had mural nodules and one case had papillary excrescences and cystic wall thickening.Irregular thickening of internal sept.was shown in the multilocular cyst cases.Two had calcification.Enhancement of the wall.internal septa and nlasses were seen in all the malignant tumors on CT scans. Metastatic lymph node was found in one cage. Conclusion There were no special clinical characteristics in difierentiation between hiliary cystadenoma and cystadenocarcinoma. Single cyst, mural nodules and papillary excrescences,irregular thickening of cystic wall and internal septa,coarse calcification and metastatic lymph node increase the likelihood of the diagnosis of the malignant tumors.But the diagnostic differentiation between cystadenoma and cystadenocarcinoma depends on pathology.
