Aldehyde dehydrogenase (ALDH) expression in paired primary and metastatic tumors from pancreatic adenocarcinoma patients*
| Patient | ALDH expression |
|
| Primary tumor | Metastatic lesion (location) | |
| A10 | Positive | Positive (periaortic lymph nodes) |
| A19 | Positive | Positive (kidney and liver) |
| A2 | Negative | Positive (liver) |
| A6 | Negative | Positive (liver) |
| A14 | Negative | Positive (liver) |
| A18 | Negative | Positive (lung) |
| A7 | Negative | Negative |
| A17 | Negative | Negative |

ALDH expression was examined by immunohistochemistry in paired primary and metastatic tumors from eight patients with pancreatic adenocarcinoma who participated in a rapid autopsy program. The lymph nodes, liver, kidney, omentum, and lungs were examined for metastases.
