Abstract
BACKGROUND: Retroperitoneal or mesenteric primary liposarcoma is a malignant neoplasia whose prognosis depends on the biological variants, the radical resection surgery and the histological subtypes, as well as on local and remote recurrences. Liposarcoma is the most common variant of this tumour among tumours of soft retroperitoneal tissue. The purpose of this study is to evaluate whether the treatment of this disease, carried out at the Ivrea Hospital for urgent reasons, may be considered in line with the experience of high-volume Centres.
PATIENTS AND METHODS: Between 1982 and 2016 five patients were hospitalized with a diagnosis of acute abdomen due to retroperitoneal or mesenteric primary liposarcoma: one myxoid of the mesentery, one well-differentiated of lesser epiploon, one well-differentiated of mesentery, and two dedifferentiates of the retroperitoneum.
RESULTS: The five patients, all males, had a average age of 59 years (range 48-86) and were all subjected to general anaesthesia and open technique for total tumour removal. Only the patient with the myxoid liposarcoma had two recurrences. All are alive and healthy after a follow-up of 177 months (range 9-420).
CONCLUSION: These tumours should be removed radically, if necessary in conjunction with contiguous organs. Rarity and therapeutic complexity require a treatment, sometimes even multimodal, in highvolume centres. Patients admitted in General Surgery Unit for unpostponable urgency should be operated by surgeons experienced in the treatment of abdominal disease to achieve survival results in line to those achievable in Hub Centres.
