RESUMO
INTRODUCTION: Statins, in the role of anti-cancer agents, have been used in many types of cancers with results in some cases promising while, in others, disappointing. AREAS COVERED: The purpose of this review is to identify and highlight data from literature on the successes or failure of using statins as anti-cancer agents. We asked ourselves the following two questions:1. Could statins, which are taken mostly to reduce cardiovascular risk, guarantee a lower incidence or a better cancer disease prognosis, concerning local recurrence, metastasis or mortality?2. Does statins intake (before and/or after cancer diagnosis) improve the prognosis or increase the chemotherapeutic action when combined with other anticancer therapies? For the first question twenty-seven manuscripts have been selected, for the second one, twenty-eight. EXPERT OPINION: There are data which correlate statins with a possible tumor suppressive action among the following cancers: breast, lung, prostate and head and neck. Lastly, for gastric cancer and colorectal there is no evidence of a correlation. The onco-suppressive efficacy of statins is mainly related to the histopathological and/or molecular characteristics of the tumor cells, which have different characteristics.

BACKGROUND: The association between KFD and autoimmune diseases, not only with systemic lupus erythematosus, has been repeatedly described. OBJECTIVE: The aim of this review is to evaluate whether an overlap syndrome is present between KFD and autoimmune diseases, whether there is a chronological and a casual relationship between the pathologies. METHODS: The databases used for the overlap case search were Medline and Embase from which we extrapolated the studies of interest. The search queries used were: Kikuchi-Fujimoto Syndrome and juvenile idiopathic arthritis or systemic lupus erythematosus or Systemic Sclerosis or Antiphospholipid Syndrome or Sjogren's Syndrome. All study types were considered (n = 103). RESULTS: Total number of included studies are 43. We have shown that there is an "overlap" syndrome between KFD and other autoimmune diseases. The chronology of disease onset was variable; autoimmune disease may be "preceding" (n = 11 cases) or "simultaneous" (n = 20 cases) or "post" (n = 8 cases). Kikuchi-Fujimoto Syndrome. Also, the autoimmune disease can present with a complete clinical picture or only with the presence of autoantibodies. CONCLUSION: the different pathologies associated with KFD with different chronologies would suggest that there is an alteration of the immune system that allows the pathologies to occur in different temporal relationships.
