BACKGROUND Aberrations in the phosphatidylinositol 3-kinase (PI3K)/mammalian target of rapamycin (mTOR)/AKT pathway are common in solid tumors. Numerous drugs have been developed to target different components of this pathway. However the prognostic value of these aberrations is unclear. METHODS PubMed was searched for studies evaluating the association(More)
BACKGROUND The ability to undertake molecular analysis to inform on prognosis and predictors of response to therapy is limited by accessibility of tissue. Measurement of total circulating free DNA (cfDNA) or circulating tumor DNA (ctDNA) in peripheral blood may allow easier access to tumor material and help to predict clinical outcomes. METHODS A(More)
BACKGROUND Neuregulins (NRG) are a family of epidermal growth factor ligands which act through binding to HER3 and HER4 receptors. NRGs are widely expressed in solid tumors. Their prognostic significance or their role as predictors of benefit from anti-HER3 therapy is not known. RESULTS Of 29 included studies, 7 studies reported the association between(More)
Companion diagnostics permit the selection of patients likely to respond to targeted anticancer drugs; however, it is unclear if the drug development process differs between drugs developed with or without companion diagnostics. Identification of differences in study design could help future clinical development. Anticancer drugs approved for use in solid(More)
BACKGROUND Companion diagnostics aim to identify patients that will respond to targeted therapies, therefore increasing the clinical efficacy of such drugs. Less is known about their influence on safety and tolerability of targeted anti-cancer agents. METHODS AND FINDINGS Randomized trials evaluating targeted agents for solid tumors approved by the US(More)
