Introduction: We investigated whether a group of pathologists could reproducibly apply the International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society (IASLC/ATS/ERS) classification for lung adenocarcinoma to a cohort of stage 1 tumors and whether this architectural classification and/or other parameters could demonstrate survival advantage.

Methods: A total of 145 cases of 7 edition of tumor, node, metastasis stage 1 adenocarcinoma were retrospectively reviewed for predominant architectural pattern, including cribriform pattern, nuclear grade, mitotic index, and necrosis. The parameters were assessed for reproducibility and survival and using multivariate analysis, compared with stage, age, and sex.

Aims: This study was undertaken to determine the validity and viability of tissue microarray (TMA) technology in assessing diagnostic immunohistochemistry (IHC) at a single laboratory site.

Methods: IHC using 57 primary antibodies was performed on a TMA paraffin block containing 89 cores of duplicate previously identified 1 mm diameter tissue specimens. IHC was interpreted by a histology scientist with IHC experience, with pathologist assistance if required.
