作者复习了1980～1989年间临床可疑肺癌而行针吸活检的196例肺内孤立性肿块的病人,年龄40～85岁,男性130例。评价了针吸活检(NB)阴性对治疗的影响。NB由透视导向进行,个别由CT导向。使用18G普通抽吸针或20G Westcott活检针。针通常通过2次,取得材料要行细胞学检查。取得小块组织时,要行组织学及细菌学检查。活检诊断为肺癌148例,其中仅2例手术证实为良性。48例未发现癌细胞,10例活检诊断为感染,余38例中19例行开胸术,其中13例为恶性,6例为良性;9例行第二次NB,7例发现癌细胞,9例中
The authors reviewed 196 patients with isolated solitary masses in the lungs who underwent needle aspiration biopsy between 1980 and 1989, aged 40 to 85 years and 130 men. The effect of negative needle aspiration biopsy (NB) on treatment was evaluated. NB is guided by perspective and individually guided by CT. Use an 18G conventional aspiration needle or a 20G Westcott biopsy needle. The needle is usually passed twice and the material is taken for cytological examination. Histological and bacteriological examinations are performed when obtaining small pieces of tissue. Biopsy diagnosed 148 cases of lung cancer, of which only 2 cases proved to be benign. No cancer cells were found in 48 cases, 10 cases were diagnosed as biopsy by infection, and 19 cases underwent thoracotomy in the remaining 38 cases, of which 13 cases were malignant and 6 cases were benign; 9 cases were treated with NB for the second time and 7 cases were found with cancer. 9 cases
