ABSTRACT
Abstract The aim of this study was to assess and compare RANK, RANKL, and OPG immunoexpression in dentigerous cyst, odontogenic keratocyst, and ameloblastoma. The protocol was registered in PROSPERO (CRD42018105543). Seven databases (Embase, Lilacs, LIVIVO, PubMed, Scopus, SciELO, and Web of Science) were the primary search sources and two databases (Open Grey and Open Thesis) partially captured the "grey literature". Only cross sectional studies were included. The JBI Checklist assessed the risk of bias. A meta-analysis with random effects model estimated the values from the OPG and RANKL ratio reported by the individual studies and respective 95% confidence intervals. The heterogeneity among studies was assessed with I2 statistics. Only nine studies met the inclusion criteria and were considered in the analyses. The studies were published from 2008 to 2018. Two studies presented low risk of bias, while seven studies presented moderate risk. The meta-analysis showed the highest OPG>RANKL ratio for dentigerous cyst (ES=43.3%; 95% CI=14.3-74.8) and odontogenic keratocyst (ES=36.8%; 95% CI=18.8-56.7). In contrast, the highest OPG<RANKL ratio was found for ameloblastoma (ES=73.4%; 95% CI=55.4-88.4) and it was higher in the stromal region compared to the odontogenic epithelial region. The results may explain the aggressive potential of ameloblastoma from the higher OPG<RANKL ratio in this tumor, while it was lower for dentigerous cyst and odontogenic keratocyst.
RESUMO
Resumo O objetivo deste estudo foi avaliar e comparar a imunoexpressão de RANK, RANKL e OPG em cisto dentígero, ceratocisto odontogênico e ameloblastoma. O protocolo foi registrado no PROSPERO (CRD [Oculto]). Sete bancos de dados (Embase, Lilacs, LIVIVO, PubMed, Scopus, SciELO e Web of Science) foram as principais fontes de pesquisa e duas bases de dados (Open Grey e Open Thesis) capturaram parcialmente a "literatura cinza". Apenas estudos transversais foram incluídos. A ferramenta JBI avaliou o risco de viés. Uma metanálise com modelo de efeitos aleatórios estimou os valores da razão OPG e RANKL relatados pelos estudos individuais e seus respectivos intervalos de confiança de 95%. A heterogeneidade entre os estudos foi avaliada por meio do teste I2. Apenas nove estudos preencheram os critérios de inclusão e foram considerados nas análises. Os estudos foram publicados entre 2008 e 2018. Dois estudos apresentaram baixo risco de viés, enquanto sete estudos apresentaram risco moderado. A meta-análise mostrou a maior razão OPG> RANKL para cisto dentígero (ES=43,3%; IC95%=14,3-74,8) e ceratocisto odontogênico (ES=36,8%; IC95%=18,8-56,7). Por outro lado, a maior razão OPG <RANKL foi encontrada para ameloblastoma (ES=73,4%; IC95%=55,4-88,4) e foi maior na região estromal em comparação com a região epitelial odontogênica. Os resultados podem explicar o potencial agressivo do ameloblastoma devido a uma maior proporção OPG <RANKL nesse tumor, enquanto tal proporção foi menor no cisto dentígero e no ceratocisto odontogênico.
