Pathologic characteristics
| Features | Values | HR | p value |
| Adenocarcinoma (n = 20) | 100% | NA | NA |
| Grade (n = 12) | 1.22 | 0.78 | |
| well | 8% | ||
| mod | 42% | ||
| Poorly | 50% | ||
| Margins status (n = 6) | NA | NA | |
| negative | 34% | ||
| positive | 66% | ||
| median nodes (n = 6) | 4 (1 – 7) | NA | NA |
Margins and nodal status were reported only for the cases initially treated with surgery (Whipple's procedure). Grade status was reported in 12 cases. Description: n = number of subjects; well = well differentiated; mod = moderately differentiated; poorly = poorly differentiated. HR = Hazard ratio for Overall Survival after univariate analysis. P value = level of significance.
