The importance of non-coding RNAs (ncRNAs) such as microRNAs (miRNAs), long non-coding (lncRNAs), and circular RNAs (circRNAs) in drug resistance mechanisms in cancer treatment has been discovered in the previous decade. Anti-angiogenic drug resistance can be influenced by ncRNA dysregulation.

Furthermore, some ncRNAs can be employed as biomarkers for anti-angiogenic drug responses and can be used to monitor cancer non-invasively. Combination treatment approaches, combined with routine anti-angiogenesis and some drugs that target the ncRNAs causing resistance, can be potential ways to overcome anti-angiogenesis resistance.
