title: Evaluation of MMP-1, MMP-8, MMP-9 serum levels in patients with adrenal tumors prior to and after surgery.
abstract: The aim of the study is to evaluate MMP-1, MMP-8 and MMP-9 serum levels in patients with adrenal tumors prior to and after surgery. Metalloproteinase-1 (MMP-1), MMP-8 and MMP-9 serum levels were evaluated in 43 patients operated on at our clinic between 1997-1999. Forty-one (95.3%) patients underwent adrenalectomy. Two (4.7%) patients were disqualified from surgery due to infiltration of adjacent tissues. MMP-1, MMP-8 and MMP-9 serum levels were determined at the admission and in case of surgery again one month after the operation. ELISA assay (K&D) was applied. Tumor type was determined on the basis of clinical, hormonal and histopathological examination. The correlation between MMP levels and tumor sizes was also evaluated. Patients were divided into 6 groups. Group I included 11 patients with adrenocortical carcinoma (4 with Cushing's syndrome and 7 with incidentalomas); group II--6 patients with benign hormonally active adrenocortical adenoma (4 with Cushing's syndrome and 2 with Conn's syndrome); group III--patients with benign, hormonally inactive adenocortical adenoma; group IV--6 patients with benign, hormonally active phaeochromocytoma; group V--4 patients with hormonally inactive phaeochromocytoma; group VI--5 patients with hormonally inactive adrenal tumors of extraglandular origin (2 myolipomas, 2 fibrolipomas, 1 hammartoma). The control group comprised 10 healthy individuals. Increased MMP-8 and MMP-9 levels were noted in patients with benign and malignant adrenal tumors. No increase of MMP levels was found in patients with tumors of extraglandular origin. The increased MMP-8 and MMP-9 levels occurred most frequently in patients with adrenocortical and hormonally active adrenomedullar cancer, and most rarely in patients with hormonally active adrenocortical tumors. MMP-8 and MMP-9 serum levels did not significantly differ between patients with adrenocortical incidentaloma cancers and in patients with benign incidentalomas. MMP-8 and MMP-9 levels were not increased in patients with inoperable adrenocortical cancers. Serum MMP-1 levels were not increased in patients with benign and malignant adrenal tumors. After surgery, MMP-8 and MMP-9 levels decreased significantly in patients with adrenocortical cancers, whereas the decrease of these MMPs in patients with benign tumors, although noticeable, was not statistically significant. MMP-8 and MMP-9 levels decreased significantly in all patients with increased preoperative levels, although they remained higher than the maximum normal values only in few patients (in 7 and 2 patients, respectively). No correlation between the levels of evaluated MMPs and tumor sizes were found.
