부임암진단에 있어서 초음파 및 전산화단층촬영 유도에 의한 세침흡인세포검사의 임상적 효용성 = Clinical efficacy of ultrasonography or Computed Tomography Guide fine needle aspiration cytology with gynecologic malignancies

다국어 초록 (Multilingual Abstract)

From January 1991 to December 1992, 47 ultrasonography(USG) or computed tomography(CT) guided fine needle aspirations (FNAs) were performed on 4 patients with gynecologic malignancies at Korea Cancer Center Hospital. The primary aspiration sites were pelvic solid mass(16), pelvic cystic mass(12), pelvic lymph node(9), paraaortic lymph node (6), lever(3), splenic hilum(1). There were 17 positive (36.2%) 23 negateive (48.9%), 5 suspicious (10.6%) and 2 inadequate (4.3%) specimens for interpretation. Excluding suspicious and inadequate specimens, the results of the evaluable aspirations were confirmed by surgical biopsy or subsequent clinical findings. As as results, USG or CT guided FNA cytology has a specificity of 100%, a sensitivity of 73.9% and a diagnostic accuracy of 85.0%. The predictive value of positive test was 100% and that of negateive test was 73.9%. The significance of clinicopathologic factors studied included the size of target lesion, the aspiration site, the primary diagnosis, the disease status, the treatment modalities, the type of radiologic guidance the initial clinical stage, the interval between diagnosis and FNAs and the histologic type. The aspiration site and the disease status were statistically significant only. These data supported that FNA is a reliable procedure in the management of gynecologic malignancies byt in negateive results , repeated FNA amy be neccessary because those results are influenced by aspiration site and disease status.
