Blank cells: not done/not ascertainable, † 0 = none, + = >0<25%, ++ = 25–75%, +++>75%, *previously reported mutations, see http://www.sanger.ac.uk/genetics/CGP/cosmic/ (SMAD4) and http://p53.free.fr/index.html (P53), @LOH, as reported by Middeldorp et al (mainly copy neutral LOH and not physical loss),8 †† 0= category 1(membranous staining), 0/+ = 2A (membranous and some nuclear staining), + = 2B (membranous & increased nuclear staining), ++ = 3 (strong nuclear & less or no membranous staining), ~2/9 markers unstable.
