Histological and clinical results of gastroscopies carried out
| Normal CgA (n = 15) | High CgA (n = 19) | P‐value | |
|---|---|---|---|
| Chromogranin A‐specific immunohistochemistry | |||
| Negative | 8 (53%) | 3 (15.8%) | 0.0087 |
| Diffuse ECL hyperplasia | 7 (47%) | 4 (26.3%) | |
| Linear ECL hyperplasia | 0 (0%) | 7 (36.8%) | |
| Micronodular ECL hyperplasia | 0 (0%) | 4 (21%) | |
| Autoimmune gastritis | 0 (0%) | 9 (47.4%) | 0.0087 |
| Chronic gastritis | 9 (60%) | 16 (84.2%) | 0.1949 |
| Helicobacter pylori positivity | 1 (6.7%) | 2 (10.5%) | 1.0000 |
| Gastroesophageal reflux disease | 10 (66.7%) | 12 (63.2%) | 1.0000 |
Unit of data is the number of observations. P‐values were the same after false discovery rate correction of multiple comparisons. CgA, chromogranin A; ECL, enterochromaffin‐like. P‐values of statistically different results between the two cohorts are indicated with bold text.
