This article has been corrected: In the Materials and Methods section, regarding the Tissue Microarray Construction, the diameter of the TMA core is incorrect. The proper value should be 1 mm, not 0.6 mm, as shown below: Tissue microarray construction For every case, all H&E stained slides were reviewed for diagnosis confirmation; one block was then selected for tissue microarray (TMA) construction. It has been demonstrated that TMAs containing at least 3 cores per case yield satisfactory agreement compared with whole section in lung cancer [14]. Therefore, for each block, 5 cores with a diameter of 1 mm were obtained randomly from the diverse areas of the tumor. Overall, 11 TMAs were built.
