Clinical and molecular heterogeneity of microsatellite instability-high colorectal cancer in older adults

Figure 2 Presumed causative mismatch repair protein deficiencies in microsatellite instability-high colorectal cancer stratified by age. The distribution of immunohistochemical loss of mismatch repair proteins is shown for the older (≥ 71 years, n = 21) and younger (≤ 70 years, n = 22) groups. Presumed causative factors were categorized based on the specific pattern of mismatch repair protein loss.
