Overview of splicing variation in ovarian cancer.

Ovarian cancer remains one of the deadliest gynecological malignancies, with a persistently high mortality rate despite promising advancements in immunotherapy. Aberrant splicing events play a crucial role in cancer heterogeneity and treatment resistance. Many splicing variants, especially those involving key molecular markers such as BRCA1/2, are closely linked to disease progression and treatment outcomes. These variants and related splicing factors hold significant clinical value as diagnostic and prognostic biomarkers and therapeutic targets. This review provides a comprehensive overview of splicing variants in ovarian cancer, emphasizing their role in metastasis and resistance, and offers insights to advance biomarker development and treatment strategies.
