Except for the report of Fischer et al. [1] who did not find either the expression of COL11A in 5 out of 15 (33.3%) colonic carcinomas analysed, we are not aware of any more studies reporting the percentage of colon adenocarcinomas expressing the COL11A1 gene; this aspect should be studied in detail. This evidence concerns the gene COL11A1 and colon carcinoma.
