Fine-needle aspiration biopsy in the diagnosis of recurrent and metastatic intraabdominal malignancies.
To evaluate the efficacy of directed percutaneous fine-needle aspiration (FNA) biopsy in the diagnosis of recurrent and metastatic intraabdominal malignancies, we reviewed our experience from 1981 to 1988. Seventy-three aspirations were performed in 73 patients. Forty-six patients with a previously treated malignancy had aspiration to diagnose either locally recurrent or metastatic disease. The remaining 27 patients had liver aspiration to rule out metastases from suspected or unknown primary sites. Computed tomography and ultrasonography were equally effective in providing diagnostic material, which was obtained from 68 of 73 aspirates. No serious morbidity occurred. Fifty-seven patients had a metastatic or recurrent malignancy, and 3 had primary hepatocellular carcinoma. Fine-needle aspiration biopsy correctly identified 51 (85 percent) of these 60 cases. There were no false-positive results and five false-negative results. Aspiration results obviated the need for a diagnostic laparotomy in 49 of the 60 patients with malignancy (82 percent). We conclude that directed percutaneous FNA biopsy is a safe and accurate method of diagnosing recurrent and metastatic intraabdominal malignancies.
