对302例肝脏占位性病变应用超声引导针吸细胞学诊断原发性肝癌,继发性肝癌,可疑癌及肝良性病变。原发性肝癌按细胞学形态、胞浆着色程度,细胞核大小,核、浆比例,核仁大小及细胞分布形态分Ⅳ级。经手术、病理、CT、动脉造影,同位素扫描及临床随访,原发性肝癌及继发性肝癌均无假阳性。并说明高分化肝细胞癌与非典型增生肝细胞单纯从细胞形态难以区别。本文说明超声引导针吸细胞学对肝脏良、恶性病变的诊断有较高临床价值。
The application of ultrasound-guided aspiration cytology to 302 cases of hepatic space-occupying lesions was used to diagnose primary liver cancer, secondary liver cancer, suspicious cancer and hepatic benign lesions. Primary liver cancer was divided into grade IV according to cytological morphology, degree of cytoplasm staining, size of nucleus, proportion of nucleus, pulp, nucleolar size and cell distribution. After surgery, pathology, CT, arteriography, isotope scan and clinical follow-up, there was no false positive for primary liver cancer and secondary liver cancer. It also shows that highly differentiated hepatocellular carcinoma and atypical hyperplasia hepatocytes are indistinguishable from cell morphology alone. This article shows that ultrasound-guided needle aspiration cytology has a high clinical value in the diagnosis of liver benign and malignant lesions.
