目前，肺癌Ⅲ期的手术切除率虽已明显提高，但仍有 １５％～ ３０％需要剖胸探查。若能在术前对原发性肺癌切除的可能性做出正确估价，无疑将更加减少不必要的开胸探查。笔者１９９６～１９９８年开胸探查的肺癌Ⅲ期２４例，结合其ＣＴ表现，探讨其对手术切除的临床意义。 临床 At present, although the surgical resection rate of stage III of lung cancer has been significantly improved, there are still 15% to 30% of cases requiring a thoracotomy exploration. If the correct assessment of the possibility of resection of primary lung cancer before surgery can be made, it will undoubtedly reduce the unnecessary exploration of thoracotomy. The authors opened the chest in 1996 to 1998 to explore the 24 cases of stage III lung cancer, combined with the CT performance, to explore its clinical significance for surgical resection. clinical
