腹膜后脂肪肉瘤是腹膜后软组织肉瘤中最常见的病理分型,早期无典型的临床表现。腹膜后腔潜在空间巨大,肿瘤生长至非常巨大时才能触及肿块或产生压迫症状,多数病人肿瘤较大时才被发现,对邻近组织器官易产生压迫或推移作用。本病的临床表现不明显,无典型症状及体征,诊断主要依靠影像学检查及病理证实。此病放化疗无明显效果,手术切除仍是此疾病最有效的治疗手段,手术切除后多为原位复发,很少远处转移。由于本病恶性程度较低,多数病人可长期生存,早期完整手术切除可显著提高该病的无瘤生存时间及总生存时间。
Retroperitoneal liposarcoma is the most common pathological type of retroperitoneal soft tissue sarcoma, no typical early clinical manifestations. The retroperitoneal space is huge, tumor growth to a very large when you can touch the mass or pressure symptoms, the majority of patients were found only when the tumor is large, easy to produce pressure on the adjacent tissues and organs or shift effect. The clinical manifestations of the disease is not obvious, no typical symptoms and signs, the diagnosis depends mainly on imaging and pathology confirmed. The disease radiotherapy and chemotherapy no significant effect, surgical removal of the disease is still the most effective treatment, mostly after surgical resection of the original recurrence, rarely distant metastasis. Due to the low degree of malignancy of this disease, most patients can survive long-term, early complete surgical resection can significantly improve the disease-free survival time and total survival time.
