Summary
Conservative surgery and chemotherapy are effective for vaginal endodermal sinus tumors (EST) in infants. Careful surgical extent and monitoring serum alpha-fetoprotein (AFP) are crucial for successful treatment and preventing recurrence.
Area of Science:
- Gynecologic Oncology
- Pediatric Oncology
- Surgical Oncology
Background:
- Vaginal endodermal sinus tumor (EST) is a rare pediatric malignancy.
- Conservative management preserving reproductive and sexual function is desirable.
Observation:
- Two cases of vaginal EST in infants are presented.
- Case 1: Partial vaginectomy and VAC chemotherapy led to no evidence of disease.
- Case 2: Local excision with VAC chemotherapy resulted in recurrence, necessitating BEP chemotherapy.
Findings:
- Conservative surgery (partial vaginectomy) combined with adjuvant chemotherapy can be effective for vaginal EST.
- Serum alpha-fetoprotein (AFP) levels are a valuable tool for diagnosis and monitoring treatment response.
- Simple tumor excision may be insufficient; recurrence can occur even with adjuvant chemotherapy.
Implications:
- Partial vaginectomy is the minimum extent for conservative surgery in vaginal EST.
- Adjuvant chemotherapy regimens (VAC, BEP) should be tailored based on AFP levels and response.
- Vaginal EST management requires a multidisciplinary approach focusing on oncologic control and functional preservation.
