28.切除轉移性肺腫瘤，下列敘述何項錯誤？
(A)原發性腫瘤沒有復發情況下，才會進行肺轉移腫瘤切除
(B)內視鏡手術切除轉移肺腫瘤已是標準手術方式
(C)可減少腫瘤負擔（tumor burden）
(D)手術前胸部的MRI不一定需要

B也是對的

Extent of resection and surgical approach — Many standard lung resections, characterized in name by the amount of lung tissue removed (eg, wedge resection, segmentectomy, lobectomy, pneumonectomy), can be used to resect pulmonary metastases using an open thoracotomy incision (anterior thoracotomy, posterior thoracotomy) or minimally invasive techniques . However, in our view (and that of the STS), minimally invasive approaches are preferred; pneumonectomy should be discouraged as it is uncommonly curative in this setting.
