Overview
Endometrial stromal sarcoma (ESS) is a rare uterine malignancy characterized by its association with endometriosis and propensity for local recurrence and distant metastasis, including infiltration into great vessels like the inferior vena cava (IVC) and right heart chambers 123456.Diagnosis
Clinical Presentation: Often presents with pelvic mass; advanced cases may show tumor thrombus extending into IVC and right heart chambers 1245.
Imaging: CT, MRI, and echocardiography crucial for assessing extent of disease, particularly in cases with cardiac involvement 124.
Pathology: Definitive diagnosis via histopathology distinguishing low-grade from high-grade ESS based on mitotic activity 124.
Grading: Low-grade ESS has better prognosis but still carries risk of recurrence (up to 56%) even decades post-surgery 24.Management
Surgical Resection: Primary treatment for localized disease; radical resection including IVC reconstruction may be necessary for extensive infiltration 34.
Adjuvant Therapy: Hormonal therapy and radiotherapy have been used post-surgery, though specific dosing details are not provided in the abstracts 1.
Cardiopulmonary Support: Complex resections involving right heart chambers may require cardiopulmonary bypass and deep hypothermic circulatory arrest 2.Special Populations
Recurrence Risk: Higher recurrence risk noted in patients with prior history of endometriosis and ovarian involvement 25.
Elderly Patients: Case reports highlight successful management in elderly patients, emphasizing individualized surgical approaches 1.Key Recommendations
Aggressive Surgical Resection: For patients with ESS involving great vessels and cardiac structures, radical surgical resection is recommended to improve recurrence-free survival (Evidence: Moderate 4).
Consider Cardiopulmonary Support: In cases with intracardiac extension, utilize advanced surgical techniques including cardiopulmonary bypass for safe resection (Evidence: Weak 2).
Monitor for Late Recurrence: Given the potential for late recurrence (up to 20 years post-surgery), long-term follow-up is essential for all patients (Evidence: Expert opinion).References
