SERUM LEPTIN LEVENS AND HEPATOCELLULAR CARCINOMA: REVIEW ARTICLE.

INTRODUCTION

Hepatocellular carcinoma is one of the most frequent types of malignant tumors in the world. There is growing evidence of the relationship between it development and obesity. The mechanism that links obesity to cancer is still not fully understood; however, it is essential to the understanding the adipose tissue in metabolic changes related to obesity and hepatocellular carcinoma.

OBJECTIVE

To review the influence of serum leptin levels in patients with hepatocelular carcinoma.

METHOD

Systematic review of the literature based on the methodology of the Cochrane Institute. The search for articles was in the database: Science Direct, Scielo, Medline, Lilacs e Pubmed. The key words used were hepatocellular carcinoma, leptin, adipokine.

RESULTS

After evaluation of individual studies, were selected seven studies. The results previously studied are still inconsistent and contradictory, and leptin can be effectively involved in the occurrence and development of hepatocellular carcinoma.

CONCLUSION

Therefore, it is necessary to develop prospective, well-designed and conducted focusing on the role and specific mechanisms of this hormone in patients with hepatocellular carcinoma, so that new correlations can be properly supported.
