Malignant Liver Mass, Retrospective evaluation of 127 patients.

Abstract

INTRODUCTION: Malignant tumors of liver are examined in two groups as primary (originating from liver tissue) and secondary (metastatic). Metastatic tumors of the liver are 20 times more common than primary liver cancers. We aimed to reveal the histopathologic diagnosis of malignant liver masses and the distribution of the organs from which metastases originated in our clinic. METHODS: We retrospectively evaluated 127 cases who were admitted to our clinic with liver mass between January 2014 and March 2016 and biopsied and diagnosed as malign tumor in pathology reports. RESULTS: A single mass was detected in 32.3% of the cases and multiple mass was detected in 67.7% of the cases. Primary liver malignancy was detected in 51 (40.2%) cases and metastasis was detected in 76 (59.8%) cases. Adenocarcinoma was the most common (51.2%) and hepatocellular carcinoma (HCC) was the second most common. Primary focus was detected in 71.8% of metastatic cases. The most common primary cancers as HCC, the most common secondary cancer has been identified as unknown primary tumor. DISCUSSION AND CONCLUSION: Metastatic tumors of the liver are detected more often than primary tumors. The most common primary tumor is HCC. The primary unknown cancers are the most common metastatic lesions of the liver. Despite efforts to prevent etiologic causes of cancer and to make the scans more conscious for early detection, liver primary and metastatic cancers continue to be a problem.
