本文采用 CT 扫描来评价65例胸片隐蔽的肺癌病灶。其中,周围型为75%(49/65)。全经病理学或细胞学证实.作者等认为 CT 对发现隐蔽的肺癌病灶比胸片更有优越性:(1)CT 有助于在隐蔽部位寻找有否原发灶,转移灶或多发灶。(2)隐蔽的肺癌病灶主要分布于10个区域但以椎旁沟处多见。(3)<3cm 的较小病灶57例(占88%),其中腺癌为41例(63%)。Ⅰ期肺癌15例(23%)。(4)探明放疗或化疗后有否残留灶。(5)可发现被胸腔渗液遮盏的肺部原发灶(19/20例,占95%)。作者等对 CT 何以能发现胸片隐蔽的肺癌病灶的原因作了讨论.
This article uses CT scans to evaluate 65 cases of hidden lung cancer lesions. Among them, the peripheral type is 75% (49/65). Fully confirmed by pathology or cytology. The authors believe that CT is more superior to the chest radiograph in detecting subtle lung cancer lesions: (1) CT can help find whether there is a primary lesion, a metastatic lesion, or multiple lesions in a hidden location. (2) Concealed lung cancer lesions are mainly distributed in 10 regions but are more common in paravertebral sulcus. (3) There were 57 cases (88%) of smaller lesions <3cm, and 41 cases (63%) of adenocarcinomas. Stage I lung cancer in 15 cases (23%). (4) To determine whether there are residual lesions after radiotherapy or chemotherapy. (5) Primary lung lesions (19/20 cases, 95%) can be found concealed by thoracic fluid. The authors discussed the reasons why CT could find hidden breast cancer lesions on chest radiographs.
