Radical trachelectomy and adjuvant vaginal brachytherapy to preserve fertility in pediatric cervical adenocarcinoma.

PURPOSE: This case report describes the use of a trachelectomy and adjuvant vaginal brachytherapy for pediatric clear cell adenocarcinoma as definitive fertility-sparing treatment.

METHODS AND MATERIALS: A previously healthy 8-year-old female presented with abdominal cramping and heavy vaginal bleeding. Diagnostic imaging revealed a 3.5 cm circumscribed cervical mass, with subsequent biopsy revealing clear cell adenocarcinoma. Fertility preserving treatment was requested.

RESULTS

The patient underwent a radical trachelectomy, with final pathology demonstrating a close radial margin. Due to close margin, adjuvant radiotherapy with a vaginal cylinder was delivered to a total dose of 18 Gray in three fractions prescribed to a depth of 5 mm from the vaginal surface using iridium-192. With 2 years of follow-up, the patient continues to do well with no evidence of recurrence or late toxicity from treatment.

CONCLUSIONS

Pediatric clear cell adenocarcinoma of the cervix is a rare occurrence that lacks clinical trials to guide effective treatment. Adjuvant vaginal brachytherapy following trachelectomy in a pediatric patient with clear cell adenocarcinoma of the cervix is feasible and well-tolerated.
