[Recurrent retroperitoneal sarcoma].

Area of Science:

• Oncology
• Surgical Oncology

Background:

• Retroperitoneal sarcomas are rare, often diagnosed late due to nonspecific symptoms.
• Prognosis remains poor despite successful initial radical surgical resection.
• Local recurrence is the most frequent pattern after initial treatment.

Purpose of the Study:

• To present a case of retroperitoneal leiomyosarcoma with local recurrence.
• To emphasize the critical role of radical surgical resection in managing recurrence.
• To highlight challenges in timely diagnosis and treatment of retroperitoneal sarcomas.

Main Methods:

• Case report of a patient with retroperitoneal leiomyosarcoma.
• Initial radical (R0) surgical resection.
• Diagnosis of local recurrence via MRI two years post-surgery.
• Second radical (R0) surgical resection with inferior caval vein resection and vascular prosthesis.

Main Results:

• Successful initial radical (R0) resection of retroperitoneal leiomyosarcoma.
• Development of local recurrence two years after initial surgery.
• Successful second radical (R0) resection, including partial inferior caval vein resection and reconstruction.

Conclusions:

• Radical surgical resection is the cornerstone of treatment for primary and recurrent retroperitoneal sarcomas.
• Timely diagnosis, though challenging, is vital for effective management.
• Surgical expertise is essential for complex resections involving vital structures.
