Gynecological malignancies, including ovarian, cervical, and endometrial cancers, present significant clinical challenges due to the epidemiological complexity and limitations in current therapeutic strategies. Emerging evidence highlights the critical role of the microbiome and its metabolites in modulating tumor initiation, progression, and treatment responses. This review explores the intricate mechanisms through which gut and reproductive tract microbiota influence gynecological cancers via immune regulation, metabolic reprogramming, and epigenetic modifications. Key microbial metabolites, such as short-chain fatty acids, bile acids, and estrogen-metabolizing intermediates, serve as molecular bridges in host-microbe communication, impacting chemotherapy resistance and immunotherapy efficacy. Furthermore, we discuss the translational potential of microbiome-targeted interventions, including probiotics, fecal microbiota transplantation, and precision microbial therapies, as innovative approaches for diagnosis, prognosis, and treatment. Understanding the microbiota-reproductive axis offers novel insights into overcoming therapeutic resistance and improving patient outcomes in gynecologic oncology.
