Rapid diagnosis of liver cancer by ultrasound-guided fine-needle aspiration biopsy.
Because of the relatively favorable prognosis to the patient with early detected hepatocarcinoma followed by surgical treatment if resection is possible, it is important to differentiate quickly between primary and secondary liver cancer. Ultrasound-guided percutaneous fine needle aspiration biopsy (US-FNAB) was used as a first diagnostic measure in patients with sonographic evidence of liver tumors. Biopsies were done under sonographic control and antiseptic conditions from the center and the border zone of solid tumors of the liver, and the aspirated cell material was air dried on glass slides and Giemsa stained. The cytologic diagnosis was proved by clinical course and in most cases by surgical or autoptic histology. Cytologic evaluation lead in 15 cases to the diagnosis of definitive or suspicious malignant liver disease; the sensitivity was 93% and the specificity was 87%. One case classified as suspicious for malignancy by cytologic examination could be identified as cirrhotic nodule by further investigations. In none of the patients did we find complications from the biopsy procedure. From these data it is concluded that US-FNAB can serve as a rapid, inexpensive, safe, and highly accurate first diagnostic step in patients with solid lesions of the liver.
