1 Cavity Wall Thickness in Solitary Cavitary Lung Adenocarcinomas Is a Prognostic Indicator 
Yukio Watanabe, MD, Masahiko Kusumoto, MD, Akihiko Yoshida, MD, Kouya Shiraishi, MD, Kenji Suzuki, MD, Shun-ichi Watanabe, MD, Koji Tsuta, MD  The Annals of Thoracic Surgery  Volume 102, Issue 6, Pages (December 2016) DOI: /j.athoracsur Copyright © 2016 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 Pathologic findings of large-vessel invasion in thick-walled cavitary adenocarcinoma as revealed by (A) hematoxylin and eosin staining (original magnification ×100) and (B) Elastica van Gieson staining (×100). Each black bar represents 1,000 μm. The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur ) Copyright © 2016 The Society of Thoracic Surgeons Terms and Conditions

3 Fig 2 The lining of the inner cavity wall. (A) The cancer cell lining type was marked by cancer cells proliferating along the inner wall of the cavity (hematoxylin and eosin; ×12.5). (B) The combined type was characterized by an inner wall composed of both cancer cells and dilated bronchi (hematoxylin and eosin; ×40). (C) The ectatic type was indicated by the inner wall being completely lined by dilated bronchi (hematoxylin and eosin; ×40). (D) An extensive area of collapsed fibrosis surrounds the dilated bronchi in the case depicted in panel (C) (Elastica van Gieson; ×40).

4 Fig 3 Histologic findings of cancer cells lining the inner wall of the cavity. (A, B) The inner wall of the thin-walled cavity was lined by papillary adenocarcinoma (hematoxylin and eosin; ×10 and ×100, respectively). (C, D) The inner wall of the thick-walled cavity was lined by solid predominant adenocarcinoma (hematoxylin and eosin; ×10 and ×100, respectively).

7 Fig 6 Overall specific survival curves for patients with thin-walled (solid lines) and thick-walled (broken lines) cavitary adenocarcinoma with (A) stage I disease (p < 0.01), (B) stage II disease (p < 0.07), and (C) stage III disease (p < 0.96).

8 Fig 7 Recurrence-free specific survival curves for patients with thin-walled (solid lines) and thick-walled (broken lines) cavitary adenocarcinoma with (A) stage I disease (p < 0.01), (B) stage II disease (p < 0.12), and (C) stage III disease (p < 0.42).
