摘要

高钙血症是癌症患者的一种重要并发症，主要由甲状旁腺激素相关肽（PTHrP）引起，很少由肿瘤产生的甲状旁腺激素（PTH）引起。我们报告了一例严重高钙血症病例，患者患有子宫癌，PTH 和 PTHrP 水平升高。手术治疗发现了已分化的子宫内膜癌。术后，PTH 和 PTHrP 水平恢复正常，但随后又因转移而升高。分子分析证实，肿瘤内存在 PTH 基因和蛋白的表达，表明存在异位 PTH 生成。在诊断和治疗癌症时，不仅要考虑 PTHrP 的产生，还要考虑异位 PTH 的产生。

Ectopic Production of Parathyroid Hormone and Production of Parathyroid Hormone-related Protein in Dedifferentiated Endometrial Carcinoma Induced Severe Hypercalcemia.

Hypercalcemia is a significant complication in cancer patients, primarily caused by parathyroid hormone-related peptide (PTHrP) and, rarely, by parathyroid hormone (PTH) production from tumors. We report a case of severe hypercalcemia in a woman with uterine cancer who exhibited elevated PTH and PTHrP levels. Surgical intervention revealed dedifferentiated endometrial carcinoma. Postoperatively, PTH and PTHrP levels normalized but subsequently increased due to metastases. A molecular analysis confirmed the expression of the PTH gene and protein within the tumor, indicating ectopic PTH production. In diagnosing and treating cancers, it is necessary to consider not only PTHrP production but also ectopic PTH production.
