本文报道了纪念医院从1960——1977年对448例肺转移瘤病人手术切除的经验;总结了手术适应症和效果;并提出随着化疗效果的增加,肺转移瘤的外科手术作用在改变。对已知原发肿瘤在肺外的病人中,孤立的肺病灶的发现,有三个可能性:(1)可能是原发癌;(2)一个良性病变;(3)转移瘤。对肺上孤立性病变,作者对性质的判断经验是:(1)如已知患的恶性肿瘤为肉瘤或恶性黑色色素瘤时,可能为转移瘤;(2)若来源于头颈部、乳腺时,可能是新的原发瘤;(3)如已知原发瘤源于胃肠道或泌尿道时,它可能是 This article reports the experience of surgical resection of 448 patients with lung metastases from the Memorial Hospital from 1960 to 1977; summarizes the surgical indications and effects; and proposes that with the increase in the effect of chemotherapy, the surgical role of lung metastases is changing.
