Precision Diagnosis and Individualized Therapy of Non‐Gestational Choriocarcinoma Invading the Corpus Uteri and Cervix: A Case Report and Literature Review

ABSTRACT Background Non‐gestational choriocarcinoma (NGCC) is a rare type of malignant tumor. Primary lesions are typically detected in the ovary and rarely invade the corpus uteri and cervix. NGCC usually has a poor prognosis due to the difficulty in achieving early and accurate diagnoses because of its rarity. Case This case described a female who was initially diagnosed with gestational choriocarcinoma and treated with EMA‐CO chemotherapy. However, subsequent short tandem repeat (STR) analysis confirmed the diagnosis as NGCC, prompting surgical intervention. Given her favorable response and after thorough communication, three additional cycles of EMA‐CO chemotherapy were recommended. At her last follow‐up, her human chorionic gonadotropin level had normalized. Conclusion This case presents a rare instance of NGCC with simultaneous uterine and cervical involvement, confirmed by STR analysis and successfully managed with the EMA‐CO regime. It highlights the necessity of precise diagnosis and personalized treatment for effective management of this disease.
