1 Optimal distance of malignant negative margin in excision of nonsmall cell lung cancer: a multicenter prospective study  Noriyoshi Sawabata, MD, Mitsunori Ohta, MD, Akihide Matsumura, MD, Katsuhiro Nakagawa, MD, Hiroshi Hirano, MD, Hajime Maeda, MD, Hikaru Matsuda, MD, PhD  The Annals of Thoracic Surgery  Volume 77, Issue 2, Pages (February 2004) DOI: /S (03)01511-X

2 Fig 1 Flow chart of patients. (NSCLC = nonsmall cell lung cancer; UDLT = undiagnosed lung tumor.) The Annals of Thoracic Surgery  , DOI: ( /S (03)01511-X)

3 Fig 2 Margin distance from tumor compared with the maximum tumor diameter according to malignant status at surgical margin of excised tumor. The margin distance from the tumor as compared with the maximum tumor diameter was 0.9 ± 0.6 cm (mean ± standard deviation) in the negative group and 0.3 ± 0.3 cm (mean ± standard deviation) in the positive group (p < ). In every positive case, the sum of the margin distance from the tumor divided by the maximum tumor diameter was less than 1. The Annals of Thoracic Surgery  , DOI: ( /S (03)01511-X)
