p40 antibody recognizes the shortest variant of human p53, and it may be a valuable marker in cases where p63 has traditionally been used. The transcription factor p63 has been identified as a p53 homologue. At present, p63 is the most frequently used marker for lung squamous cell carcinoma (SqCC). In a recent study, p40 staining was equivalent to p63 in sensitivity for SqCC, but was exhibited markedly superior specificity vs. p63. This report strongly supports the routine use of p40 as an alternative for p63 when used in the diagnosis of pulmonary squamous cell carcinoma. p40 may prove to be an important antibody in the differential diagnosis of lung adenocarcinoma vs. lung SqCC.
