Fertility-preserving local excision under a hysteroscope with combined chemotherapy in a 6-year-old child with clear cell adenocarcinoma of the cervix: A case report and review of the literature.

introductionClear cell adenocarcinoma of the cervix (CCAC), a rare and more severe type of gynecological cancer, is especially rare in pediatric patients. Traditionally, surgery following chemotherapy (CT) and radiation therapy is the preferred treatment for CCAC; however, patients have poor 5-year survival rates than other types of cervical cancers. PATIENT CONCERNS: A 6-year-old girl with a history of vaginal discharge for 18 months was diagnosed with CCAC by histological examination. Her parents refused the traditional treatment of radical hysterectomy and lymph node dissection because of her young age. DIAGNOSIS: The patient's tests revealed negative human papilloma virus and negative methylated paired box 1 gene results. The tumor mass histopathology revealed stage IIA1 CCAC that originated from the cervix.

interventionsTumor mass excision with preservation of the cervix by electrosurgical biopsy under hysteroscopy was performed. Four cycles of docetaxel and oxaliplatin CT were administered every 3 weeks. OUTCOMES: No signs of recurrence were observed in the 28 months after final treatment and diagnosis on magnetic resonance imaging, color ultrasonic imaging, and gynecological examination. Serologic tumor biomarkers were also within normal ranges.

conclusionsThis is the first reported CCAC case in which the primary treatment included electrosurgical biopsy of the polypoid mass under hysteroscopy, followed by CT without traditional treatment: radical surgery with pelvic and/or lymphadenectomy for fertility preservation. This is a new treatment approach for young CCAC patients without the use of surgery.
