title: Clinical evaluation of serum aminoterminal propeptide of type III procollagen as tumor marker in gynecologic malignancies.
abstract: OBJECTIVE
  The aim of this study was to determine the possible usefulness of the assay of the aminoterminal propeptide of type III procollagen and fibronectin in detecting connective tissue changes associated with gynecologic malignancies.
  
  
  METHODS
  Serum aminoterminal propeptide of type III procollagen and plasma fibronectin were measured in 36 women with gynecologic malignancies, 20 women with benign gynecologic tumors and 10 healthy women serving as controls.
  
  
  RESULTS
  A significant serum propeptide was significantly high in the group with gynecologic malignancies and normal in the benign tumor group. The serum propeptide levels were related to of disease stage and presence of ascites in patients with ovarian carcinoma but not in those with cervical or endometrial carcinoma. In the follow-up study, a favorable clinical response was associated with normalizing propeptide levels whereas in rapidly progressive disease the levels fell initially but rose again. In partial response with ultimate progression, the propeptide concentration decreased but remained clearly above the normal range. No difference in plasma fibronectin was found among the malignant tumor, benign tumor and control groups.
  
  
  CONCLUSIONS
  The present study indicates that the aminoterminal propeptide of type III procollagen could serve as an additional, non specific marker to follow the clinical behavior of gynecologic malignancies and consequently of connective tissue metabolism reflecting tumor matrix interaction.
