| 1 | 腹膜后去分化脂肪肉瘤的CT诊断(附7例报道及文献复习)显示文摘目的探讨腹膜后去分化脂肪肉瘤(Dedifferentiated1iposareoma,DDLS)的CT表现,以提高对该病的认识。方法回顾性分析7例经病理证实的去分化脂肪肉瘤的CT资料,7例均行CT平扫及增强扫描。首次发病年龄42-77岁,平均54岁,男4例,女3例。结果4例表现为混合密度肿块,脂肪密度肿块边见一软组织密度肿块,2种成分之间分界清楚;3例表现为软组织密度肿块,瘤内脂肪成分小于10%。去分化成分,平扫与软组织密度相似,增强呈显著不均匀强化,有延迟强化。结论 DDLS是一种少见类型的脂肪肉瘤,CT表现具有一定特点,可为临床诊断提供有价值的信息。 | 闻芳 胡春洪 胡粟 戴启春 | 2014 | 中国CT和MRI杂志2014，12，4： | 8 |
| 2 | 腹膜后巨大脂肪肉瘤1例并文献复习显示文摘目的:探讨腹膜后脂肪肉瘤的诊断和治疗,提高少见病例的诊疗水平。方法回顾江汉大学附属医院收治的1例腹膜后巨大脂肪肉瘤患者的临床资料,结合文献讨论腹膜后脂肪肉瘤的临床特点以及诊断、治疗方法。结果患者经影像学诊断后行左侧腹膜后肿瘤切除+左肾部分切除术,术后病理提示腹膜后脂肪肉瘤,手术顺利,术后随访20个月,未见肿瘤复发及转移。结论腹膜后脂肪肉瘤临床少见,无特异性临床表现,CT有助于该病的诊断,手术是首选的治疗方法。 | 朱涛 刘涛 方登攀 | 2014 | 实用肿瘤学杂志2014，28，5： | 2 |
| 3 | Recurrent abdominal liposarcoma: Analysis of 19 cases and prognostic factors显示文摘AIM: To evaluate the clinical outcome of re-operation for recurrent abdominal liposarcoma following multidis-ciplinary team cooperation. METHODS: Nineteen consecutive patients who had re-current abdominal liposarcoma underwent re-operation by the retroperitoneal sarcoma team at our institution from May 2009 to January 2012. Patient demographic and clinical data were reviewed retrospectively. Multidisciplinary team discussions were held prior to treatment, and re-operation was deemed the best treatment. The categories of the extent of resection were as follows: gross total resection (GTR), palliative resection and partial resection. Surgical techniques were divided into discrete lesion resection and combined contiguous multivisceral resection (CMR). Tumor size was determined as the largest diameter of the specimen. Patients were followed up at approximately 3-monthly intervals. For survival analysis, a univariate analysis was performed using the Kaplan-Meier method, and a multivariate analysis was performed using the Cox pro-portional hazards model. RESULTS: Nineteen patients with recurrent abdominal liposarcoma (RAL) underwent 32 re-operations at our institute. A total of 51 operations were reviewed with a total follow-up time ranging from 4 to 120 (47.4 ± 34.2) mo. The GTR rate in the CMR group was higher than that in the non-CMR group (P = 0.034). CMR was positively correlated with intra-operative bleeding (correlation coefficient = 0.514, P = 0.010). Six cases with severe postoperative complications were recorded. Patients with tumor sizes greater than 20 cm carried a significant risk of profuse intra-operative bleeding (P = 0.009). The ratio of a highly malignant subtype (de-differentiated or pleomorphic) in recurrent cases was higher compared to primary cases (P = 0.027). Both single-factor survival using the Kaplan-Meier model and multivariate analysis using the Cox proportional hazards model showed that overall survival was corre-lated with resection extent and pathological subtype (P < 0.001 and P = 0.02), however, relapse-free interval (RFI) was only correlated with resection extent (P = 0.002). CONCLUSION: Close follow-up should be conducted in patients with RAL. Early re-operation for relapse is preferred and gross resection most likely prolongs the RFI. | Wei Lu James Lau Mei-Dong Xu Yong Zhang Ying Jiang Han-Xing Tong Juan Zhu Wei-Qi Lu Xin-Yu Qin | 2013 | World Journal of Gastroenterology2013，19，25： | 2 |
| 4 | 腹膜后巨大脂肪肉瘤1例显示文摘脂肪肉瘤是一种软组织恶性肿瘤,发病率较低,占恶性肿瘤的1%,多见于50岁以上成年人。而腹膜后脂肪肉瘤相对少见,占全部脂肪肉瘤的33%-45%。由于其位置深、发病隐匿,常常在肿瘤巨大、侵犯或挤压周围脏器发生合并症状时才能发现,因此,腹膜后脂肪肉瘤常常发现时已经侵犯重要脏器和大血管,而且范围巨大,手术难度大,难以完全切除。 | 赵新明 郭彩霞 陈亚红 姜珊 | 2018 | 中国实验诊断学2018，22，4： | 0 |
