Trattamento chirurgico di un voluminoso liposarcoma mixoide retroperitoneale plurirecidivo

Retroperitoneal liposarcoma is a malignant neoplasm characterized by a high recurrence rate, varying from 35% to 82%, with a disease-free period of three years. Only in 25% of the cases it is possible to reveal distant metastasis. The elective treatment of the local recurrence is represented by the radical surgical ablation. Nowadays radiotherapy and/or chemiotherapy give poor results both in the treatment of the primary tumor and in the treatment of its recurrence. The Authors describe a case of retroperitoneal mixoid liposarcoma recurred many times.
