Predictive Value of the International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society Classification of Lung Adenocarcinoma in Tumor Recurrence and Patient Survival

Outcomes of lung adenocarcinoma classified according to the new IASLC/ATS/ERS system were evaluated in this retrospective single-institution study involving 573 pts who underwent surgical treatment.  Histologic patterns were associated with sex and tumor TNM factors.  Recurrence was higher in micropapillary and solid-predominant cancers.  These subtypes were also associated with poorer overall and disease-specific survival compared to other types.
