1 Lobe-specific extent of systematic lymph node dissection for non–small cell lung carcinomas according to a retrospective study of metastasis and prognosis  Hisao Asamura, MD, Haruhiko Nakayama, MD, Haruhiko Kondo, MD, Ryosuke Tsuchiya, MD, Tsuguo Naruke, MD  The Journal of Thoracic and Cardiovascular Surgery  Volume 117, Issue 6, Pages (June 1999) DOI: /S (99) Copyright © 1999 Mosby, Inc.

2 Fig. 1 Survival curve for all 166 patients with lung carcinoma with mediastinal lymph node metastasis. Five-year survival was 35%. Numbers in parentheses indicate number of patients still at risk at every postoperative year. The Journal of Thoracic and Cardiovascular Surgery  , DOI: ( /S (99) ) Copyright © 1999 Mosby, Inc. Terms and Conditions

3 Fig. 2 Survival curves of patients with single-station metastases (MET) and multiple-station metastases. Five-year survivals for patients with single-station metastases and multiple-station metastases were 48% and 18%, respectively. Statistically significant difference between groups was observed (log rank test, P = .0006). Numbers in parentheses indicate number of patients still at risk at every postoperative year.

4 Fig. 3 Survival curves of patients with single-node metastases (MET) and multiple-node metastases. Five-year survivals for patients with single-node metastases and multiple-node metastases were 55% and 20%, respectively. Statistically significant difference between groups was observed (log rank test, P = .0002). Numbers in parentheses indicate number of patients still at risk at every postoperative year.

5 Fig. 4 Survival curves of patients with and without subcarinal node (station 7) metastases among 54 patients with right upper lobe (RUL) tumors. There was no statistically significant difference between groups (log rank test, P = .97). Numbers in parentheses indicate number of patients still at risk at every postoperative year.

6 Fig. 5 Survival curves of patients with and without superior mediastinal node metastasis (from station 1 through station 4) in 41 right lower lobe tumors. Five-year survival for patients with superior mediastinal metastasis was 4.1%. There was no statistically significant difference (log rank test, P = .55). Numbers in parentheses indicate the number of patients still at risk at every 1 year after surgery. The Journal of Thoracic and Cardiovascular Surgery  , DOI: ( /S (99) ) Copyright © 1999 Mosby, Inc.
