A greater percentage of thyroid cancers can be detected by ultrasound-guided fine-needle aspiration biopsy (UG-FNAB) than by ordinary FNAB. A group of 678 patients were selected sequentially as having been diagnosed with benign nodules by the conventional FNAB method. We reexamined these patients by UG-FNAB and investigated the types of thyroid cancer that were missed by the conventional FNAB. Of the 678 patients diagnosed with benign nodules (using conventional FNAB), 571 (84.2%) demonstrated the same diagnosis when UG-FNAB was used. The remaining 107 patients (15.8%) studied were suspected of having a malignancy after UG-FNAB had been performed. Surgical specimen histology proved thyroid cancer in 99 of the 107 patients: 93 had papillary carcinoma, 4 had follicular carcinoma, 1 had medullary carcinoma and 1 had anaplastic carcinoma. Two drawbacks were noted when conventional FNAB was used: (1) cancer lesions difficult to palpate (: n = 55) (e.g., small cancers with or without benign lesions or cancers associated with Hashimoto's thyroiditis or Graves' disease); and (2) palpable cancers with insufficient cell material for analysis ( n = 44) (e.g., cystic carcinoma and cancers with calcified lesions. UG-FNAB is a powerful technique for detecting microcancers, cystic carcinomas, cancers associated with benign nodules, Hashimoto's thyroiditis, or coarse calcifications. 1996 by the Société Internationale de Chir, ugie Yokozawa Tamotsu Kuma Hospital, 8-2-35 Shimoyamate Dori, Chuo-ku, Kobe 650, Japan, JP aut Fukata Shuji Kuma Hospital, 8-2-35 Shimoyamate Dori, Chuo-ku, Kobe 650, Japan, JP aut Kuma Kanji Kuma Hospital, 8-2-35 Shimoyamate Dori, Chuo-ku, Kobe 650, Japan, JP aut Matsuzuka Fumio Kuma Hospital, 8-2-35 Shimoyamate Dori, Chuo-ku, Kobe 650, Japan, JP aut Kobayashi Akira Kuma Hospital, 8-2-35 Shimoyamate Dori, Chuo-ku, Kobe 650, Japan, JP aut Hirai Keisuke Kuma Hospital, 8-2-35 Shimoyamate Dori, Chuo-ku, Kobe 650, Japan, JP aut Miyauchi Akira Second Department of Surgery, Kagawa Medical School, Kagawa, Japan, JP aut Sugawara Masahiro Medical and Research Services, West Los Angeles Veterans Affairs Medical Center and University of California Los Angeles, School of Medicine, Los Angeles, California, 90073, U.S.A., US aut https://doi.org/10.1007/s002689900129 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1007/s002689900129 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Yokozawa Tamotsu Kuma Hospital, 8-2-35 Shimoyamate Dori, Chuo-ku, Kobe 650, Japan, JP aut NATIONALLICENCE 700 1- Fukata Shuji Kuma Hospital, 8-2-35 Shimoyamate Dori, Chuo-ku, Kobe 650, Japan, JP aut NATIONALLICENCE 700 1- Kuma Kanji Kuma Hospital, 8-2-35 Shimoyamate Dori, Chuo-ku, Kobe 650, Japan, JP aut NATIONALLICENCE 700 1- Matsuzuka Fumio Kuma Hospital, 8-2-35 Shimoyamate Dori, Chuo-ku, Kobe 650, Japan, JP aut NATIONALLICENCE 700 1- Kobayashi Akira Kuma Hospital, 8-2-35 Shimoyamate Dori, Chuo-ku, Kobe 650, Japan, JP aut NATIONALLICENCE 700 1- Hirai Keisuke Kuma Hospital, 8-2-35 Shimoyamate Dori, Chuo-ku, Kobe 650, Japan, JP aut NATIONALLICENCE 700 1- Miyauchi Akira Second Department of Surgery, Kagawa Medical School, Kagawa, Japan, JP aut NATIONALLICENCE 700 1- Sugawara Masahiro Medical and Research Services, West Los Angeles Veterans Affairs Medical Center and University of California Los Angeles, School of Medicine, Los Angeles, California, 90073, U.S.A., US aut Metadata rights reserved Springer special CC-BY-NC licence nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-springer
