Anatomical site of tumour compared with allelic imbalance (AI) on chromosome 12q and ethnicity

CardiaBodyAntrump Value
The anatomical site of origin of the tumour could be determined for 66% of the 76 tumours.
*Fisher’s exact test, when the table is collapsed into a 2×2 table comparing white with minority for anatomical site (cardia versus body+antrum). If the grouping is (cardia+body) versus antrum, p=0.023. †Fisher’s exact test, when table is collapsed into a 2×2 table comparing (cardia+body) versus antrum for AI on chromosome 12q.
