N6-methyladenosine (m6A) RNA modification plays a pivotal role in gynaecological cancers by regulating tumor initiation, progression, and therapeutic resistance. m6A RNA modification include writers (METTL3/14, RBM15, ZC3H13, WTAP), which catalyze methylation; erasers (ALKBH5, FTO), which remove methyl groups; and readers (YTHDC1, YTHDF1/2/3, IGF2BP1/2/3, HNRNPC/G, HNRNPA2BP1), which interpret m6A marks to regulate the RNA fate. These regulators alter basic RNA metabolism, such as splicing, mRNA stability, translation, and degradation. In gynaecological cancers, both oncogenic and tumor suppressive signaling pathways are also altered by these regulators. Due to their diagnostic, prognostic and predictive value, m6A regulators have emerged as promising biomarkers in gynaecological cancers in recent years. This review highlights the role of m6A regulators and critically evaluates their biomarker and clinical potential in gynaecological cancers.
