Abstract:
Objective:To analyze the operative outcomes and postoperative pathological features of retroperitoneal leiomyosarcoma(RPLMS) undergoing surgeries.Methods:Medical records of RPLMS patients admitted to Peking University International Hospital from Jan 2015 through Dec 2020 were retrospectively reviewed.Results:Ninety-seven patients undergoing resectional surgeries were included in the study. Of whom, 49 cases were primary RPLMS. Others were recurrent sarcomas or sarcomas with incomplete resection in the first surgical intentions. The most frequent symptoms were abdominal pain and distention (30 cases) as well as lower back pain (23 cases). All patients underwent resectional surgeries with a R 0/R 1 rate of 84.5%. Sixty-four cases received extended surgeries with combined organs resection. External iliac artery resection with reconstruction were performed on 2 cases. And 19 patients underwent partial IVC resection in combination of sarcoma resection. The general postoperative morbidity was 26.8%, including 4 intestinal fistulas, 1 pancreatic fistula, 1 vesicovaginal fistula, 1 urinary fistula, 1 biliary fistula, 2 abdominal major bleeding, 7 IVC thrombosis, 3 gastroplegiaetc. One patient deceased within post-operative 30 d due to massive bleeding.Pathology found that spindle and pleomorphic cell types were most common subtypes of RPLMS. Conclusions:Surgery remains the mainstay in the treatment of RPLMS which often presents with atypical symptoms. Extended surgeries combining with multiple organ and major vascular resections could be only suggested in experienced sarcoma centers due to high risk of severe postoperative complications.
