Retraction Notice: Adenocarcinoma of the lung with scattered consolidation: Radiological–pathological correlation and prognosis

a b s t r a c t Purpose: To investigate the clinicopathological features and prognosis in patients with adenocarcinoma of the lung with scattered consolidation (ALSC). Materials and methods: Between January 2006 and March 2010, 139 consecutive patients with lung adenocarcinoma of ≤3 cm, who underwent pulmonary resection for lung cancer, were investigated ret- rospectively. Radiologic classification was based on the findings of thin-section CT such as the presence of consolidation or ground-glass opacity (GGO). Type I (n = 15) and Type II (n = 14), showed a pure GGO and a mixed GGO with consolidation <50%, respectively. Type IV (n = 38) and Type V (n = 52) showed a mixed GGO with consolidation ≥50% and a pure consolidation, respectively. Type III (n = 20) was the adenocarcinoma of the lung with scattered consolidation (ALSC). The clinicopathological features and prognosis of ALSC was investigated with comparative analysis and survival analysis. Results: Because of the similar recurrence rate for Type I and Type II (P = 1.000), Type IV and Type V (P = 0.343), we merged Type I and Type II as Type I + II, Type IV and Type V as Type IV + V, respectively. In the 20 (14.4%) patients with ALSC, lymph node metastasis was not observed, and it was rare in lymphatic invasion and vascular invasion. On the basis of IASLC/ATS/ERS 2011 classification, 80% of the ALSC were preinvasive lesions. In Noguchi classification, there was no significant difference between Type I + II and ALSC (P = 0.260). The prognosis of ALSC was similar to Type I + II (P = 0.408), but better than Type IV + V (P = 0.040). Conclusion: Adenocarcinoma of the lung with scattered consolidation (ALSC) on thin-section CT was a relatively favorable prognostic factor. © 2013 Elsevier Ireland Ltd. All rights reserved.
