The authors reported a rare clinical case of successful surgical treatment of young female with retroperitoneal leiomyosarcoma followed by lesion of the cavarenal segment of inferior vena cava, left renal vein. Clinical and morphological features of disease, postoperative outcomes and prognostic factors in patients with retroperitoneal leiomyosarcoma are discussed.

[Experience of surgical treatment of abdominal and intraabdominal desmoid fibromas].

It is presented the treatment results of abdominal and intraabdominal desmoid fibromas. Group of abdominal localization included 19 patients. 15 of them had primary tumors, 4 - recurrent tumors after surgical treatment. Radical (R0) operations were performed in all cases. Tumor removal was associated with plastic of abdominal wall by synthetic implant in 17 patients. Wide excision of surrounding tissues and musculo-aponeurotic layer of anterior abdominal wall allows to achieve long-term disease-free period. There weren't recurrent symptoms in terms from 4 to 60 months of observation. The second group included 28 patients with intraabdominal desmoid fibromas. Operations were performed in 11 (35.2%) patients including 3 cases of reoperations. There were 14 operations. Radical (R0) volume was applied in 11 (78.6%) operations, cytoreductive (R2) volume - in 1 (7%) operation. Explorative laparotomy was used in 3 (21.4%) cases because of involvement of mesenteric vessels. Combined treatment was performed in 4 (14.3%) patients. 14 (50%) patients received conservative therapy because of unresectable tumor including chemo-, hormone- and radiotherapy. Operated patients were under observation in terms from 11 to 156 months, median was 63.2 months. Recurrence developed in 4 of 10 (40%) patients after R0-surgery. Cytoreductive (R1/R2) volume is admitted for intraabdominal desmoid fibromas. But even in case of unresectable process and explorative intervention stabilization and regression of tumor is possible by means of chemo-, hormone- and radiotherapy in different combination. It allows to preserve a good life quality.
