Risk for atypia and carcinoma in large parathyroid tumors is not known. Atypia and carcinoma were determined in small (<2 g) and large (≥2 g) tumors in patients undergoing parathyroidectomy for primary hyperparathyroidism.
The study was a retrospective analysis of a 5-year prospective database. Tumor weight, histopathology, age, gender, calcium, and parathyroid hormone levels were registered. Patients with 4-gland disease were not included.
Among 353 parathyroid tumors, 313 weighed <2 g and 40 weighed ≥2 g. There was no difference in age between groups. Patients with large tumors were more frequently men and had higher calcium and parathyroid hormone levels. Atypia was found in 4 of 313 (1.3%) and 7 of 40 (17.5%) small and large tumors, respectively (P < .05). Corresponding figures for carcinoma were 1 of 313 (.3%) and 2 of 40 (5.0%) (P < .05).
Large parathyroid tumors have increased risk for atypia and carcinoma. Even so, most large parathyroid tumors are benign.
大型甲状旁腺瘤发生非典型性和癌的风险尚不清楚。本研究通过对原发性甲状旁腺功能亢进症患者行甲状旁腺切除术,分析了小(<2g)大和(≥2g)大甲状旁腺肿瘤中非典型性和癌的发生情况。
这是一项为期 5 年的前瞻性数据库的回顾性分析。记录了肿瘤重量、组织病理学、年龄、性别、钙和甲状旁腺激素水平。不包括 4 腺体疾病患者。
在 353 个甲状旁腺肿瘤中,313 个肿瘤<2g,40 个肿瘤≥2g。两组患者的年龄无差异。大肿瘤患者中男性更多,血钙和甲状旁腺激素水平更高。小肿瘤中 4 个(1.3%)和大肿瘤中 7 个(17.5%)存在非典型性(P<.05)。相应的癌发生率分别为小肿瘤 1 个(0.3%)和大肿瘤 2 个(5.0%)(P<.05)。
大型甲状旁腺肿瘤发生非典型性和癌的风险增加。即便如此,大多数大型甲状旁腺肿瘤仍为良性。
