Fertility-sparing management combined with photodynamic therapy for endometrial stromal sarcoma: a case report.

Background And Objectives: Low-grade endometrial sarcoma (LGESS) has a favorable prognosis after standard surgical treatment. The conservative fertility-sparing treatments in young patients with LGESS have been reported; however, the role of conservative therapy is not well defined.

Study Design/patient And Methods: A 31-year-old nulliparous woman was diagnosed with LGESS after resection of a cervical polyp with resection margin positive for malignancy. She underwent fertility-sparing surgery including laparoscopic pelvic lymph node dissection, hysteroscopic endometrial polypectomy, endocervical curettage, and photodynamic therapy (PDT) on the endometrium and uterine cervix. And she had received adjuvant therapy with a non-steroidal aromatase inhibitor.

Results: She conceived by in vitro fertilization and delivered twins at 32+2 weeks gestation by Cesarean section 32 months after conservative treatment. She has no evidence of recurrence after 99 months of follow-up.

Conclusion: Conservative management of LGESS may be attempted in selected patients who want to preserve fertility. Conservative surgery combined with PDT has shown effective results in long-term follow-up.
