Three cases of retroperitoneal liposarcoma are reported with review of several papers in the Japanese literature.The first case, a 65-year-old woman, underwent four exploratory laparotomies and is alive for 3 years. The second case, a 76-year-old man, developed a recurrent retroperitoneal liposarcoma 2 years after initial surgery, and underwent re-laparotomy with a rectal cancer resection. The third case, an 85-year-old man, has been followed up as for 6 months after initial laparotomy. Some reviews of the literature revealed that there is no characteristic symptom even in the advantaged stage of retroperitoneal liposarcoma, and so most tumors grow huge at the diagnosis. Complete resection is the only effective treatment for peritoneal liposarcoma with combined resection of adjacent organs. Local recurrence frequently occurred with high probability. However, the patients with recurrent tumor that had been resected curatively showed similar survival rate compared to that of those with curatively resected tumor at initial operation. In order to improve the therapeutic results of retroperitoneal liposarcomas, early detection of postoperative recurrence and repeated curative operations have to be performed.
