| Popis: | Hepatic scintigraphy was performed prior to surgical exploration in 89 patients with primary carcinoma of the large bowel. Of these patients, 26% had positive liver scans at the time the diagnosis was established. The presence or absence of liver metastasis by scintigraphic criteria was correlated with surgical findings, a modified Duke pathologic classification, and the presence of tumor markers. The sensitivity of hepatic scintigraphy was 96% and the specificity was 98%. A total of 63% of patients with abdominal lymph node involvement had positive liver scans while 4.6% of patients without lymph node involvement had positive scans. A total of 91% of patients with positive liver scans had positive abdominal nodes. Of 60 patients with normal liver scans, one (1.7%) had hepatic metastasis and 27% had tumor in regional lymph nodes. Hepatic scintigraphy is highly sensitive in detecting liver metastasis from large bowel carcinoma. However, a negative liver scan did not exclude abdominal lymph node spread. |
