Table 1 PSMA vascular expression in primary and metastatic tumors

From: Peritumoral/vascular expression of PSMA as a diagnostic marker in hepatic lesions

  PSMA vascular expression
Case (n) Positive (n,%) Negative (n,%)
Primary 42 28(66.7%) 14(33.3%)
 HCC 22 15(68.2%) 7(31.8%)
 Cholangiocarcinoma 15 13(86.7%) 2(13.3%)
 Hepatic adenoma 5 0(0.0%) 5(100.0%)
Metastatic 30 2(6.7%) 28(93.3%)
 Pancreatic ductal 18 0(0.0%) 18(100.0%)
 Other sites* 12 2(16.6%)** 10(83.3%)
  1. *Other sites includes liver metastatic tumor original from colon (3), lung (1) and prostate (8)
  2. **In total 5 cases of metastatic prostate cancer showed positivity in PSMA, 2 of which had both tumor cell and peritumoral/vascular pattern, and the rest 3 cases were tumor cell positive only (counted in negative column)
