Tumor-produced high molecular weight insulin-like growth factor-II (big insulin-like growth factor-II) is considered to cause non-islet cell tumor hypoglycemia. This paper presents a case of surgically resected retroperitoneal liposarcoma that produced big insulin-like growth factor-II.
Here, we report the case of a 62-year-old woman who presented with an abdominal mass and hypoglycemia. Non-islet cell tumor hypoglycemia due to retroperitoneal liposarcoma was suspected. After complete resection of the tumor, the patient's hypoglycemia improved and big insulin-like growth factor-II disappeared in the molecular weight analysis of serum insulin-like growth factor-II by western blotting. The patient had no tumor recurrence or reappearance of hypoglycemia 16 months after the operation without any adjuvant therapy.
Although insulin-like growth factor-II-producing tumors are generally large and difficult to operate on, surgical resection is currently the most effective and only treatment; thus, it is essential to attempt resection aggressively.
肿瘤产生的高分子量胰岛素样生长因子-II(大胰岛素样生长因子-II)被认为会导致非胰岛细胞瘤性低血糖症。本文介绍了一例经手术切除的产生大胰岛素样生长因子-II的腹膜后脂肪肉瘤病例。
在此,我们报告一例62岁女性患者,该患者出现腹部肿块和低血糖症。怀疑是腹膜后脂肪肉瘤导致的非胰岛细胞瘤性低血糖症。肿瘤完全切除后,患者的低血糖症得到改善,并且在通过蛋白质印迹法对血清胰岛素样生长因子-II进行分子量分析时,大胰岛素样生长因子-II消失。术后16个月,患者未接受任何辅助治疗,无肿瘤复发,也未再次出现低血糖症。
尽管产生胰岛素样生长因子-II的肿瘤通常体积较大且手术难度大,但手术切除目前是最有效且唯一的治疗方法;因此,积极尝试切除至关重要。
