Abstract In this study the entire p53 complementary DNA has been sequenced in 20 non-small cell lung carcinomas (NSCLC) and the results correlated with chemosensitivity, immunohistochemistry and clinical data. Ten patients had mutations in p53, 8 missense mutations and 2 nonsense mutations. The method discovered two mutations never described previously and two other mutations that have never been described before in connection with NSCLC tumours. Chemosensitivity data, according to a short-term assay (FMCA), indicated that tumours with p53 mutation were more resistant to cisplatin and cyclophosphamide. Immunohistochemical studied demonstrated a 70\% concordance between over-expression of p53 protein and mutation in p53. No conclusions or trends could be drawn from the immunohistochemical studies of Bcl-2 and Bax.
