  • The Diagnosis and Treatment of Parathyroid Carcinoma

    目的:总结和探讨甲状旁腺癌的诊断和治疗方法。方法:回顾性总结本院5例甲状旁腺癌的临床资料。结果:5例患者术前颈部均扪及质硬包块,平均血钙浓度为3.82 mmol/L,平均PTH浓度为153.6 pmol/L,4例术中发现周围浸润表现。5例中4例同时行甲状旁腺肿瘤和同侧甲状腺腺叶切除,1例仅行甲状旁腺肿瘤切除。5例术后均诊断为甲状旁腺癌。术后4例得到随访,时间4月~5年。其中2例术后无复发;1例于术后半年局部复发行患侧甲状腺切除,后无复发;1例因全身转移于术后8个月死亡。结论:甲状旁腺癌的诊断非常困难,异常高浓度血钙、血PTH及术中浸润表现和组织病理学特征是甲状旁腺癌诊断的重要依据,99m-Tc-MIBI扫描及超声是病变定位的首选手段,肿瘤及其周围受侵组织的“整块切除”(en bloc resection)是首选的治疗方式。

  • Experience of Diagnosis and Treatment of 136 Patients with Primary Hyperparathyroidism

    ObjectiveTo analysis the clinical symptoms, diagnosis, and treatment of primary hyperparathyroidism (PHPT). MethodsA retrospective study was made in consecutive patients with PHPT who performed operation and had integral data between January 2004 to December 2012 in West China Hospital. ResultsThe 136 cases were composed of 52 cases (38.23%) bone types, 17 cases (12.50%) nephrocalcinosis, 7 cases (5.15%) skeletal and renal involvements, 24 cases (17.65%) asymptomatic primary hyperparathyroidism, and 36 cases (26.47%) combined with other clinical symptoms. The preoperative parathyroid hormone (PTH) levels were (106.20±88.88) pmol/L (6.91-390 pmol/L) and serum calcium were (3.12±0.66) mmol/L (2.15-5.77 mmol/L). The coincidence rate between the examinations preoperation and pathology:B type ultrasound was 75.00%, 99Tcm-MIBI scan was 85.29%, ultrasound and 99Tcm-MIBI combined with computerized tomography (CT) scan was 86.76%. Pathology presentation:129 patients (94.85%) were benign lesions, 7 cases (5.15%) were parathyroid carcinoma. Of the 129 patients, 114 cases (95.80%) were single parathyroid adenoma, 5 cases (4.20%) were multiple parathyroid adenoma or combined parathyroid hyperplasia, 10 cases (7.75%) were parathyroid hyperplasia. Of the patients, the PTH level decreased to below normal upper limit within 3 days after surgery in 124 cases (91.18%). One hundred and twenty-four cases (91.18%) were followed-up. The follow-up time was 6-112 months, a median follow-up time was 49 months. Twelve patients (8.82%) were lost to follow-up, 2 patients (1.47%) with carcinoma recurrence, the rest patients without recurrence and metastasis. Three patients (2.20%) with parathyroid carcinoma died. Of the 3 patients, 2 died of systemic metastasis of parathyroid carcinoma in 18 and 23 months after surgery, 1 died of cardiovascular accident in 19 months after surgery. ConclusionSurgical excision of the lesion parathyroid tissue is the most effective treatment for PHPT.

  • Diagnosis and Treatment of Parathyroid Carcinoma: A Report of 7 Cases

    ObjectiveTo explore the diagnosis and treatment features of parathyroid carcinoma (PTC). MethodsThe clinical data of 7 cases of parathyroid carcinoma treated from January 1993 to April 2014 were analyzed retrospectively. ResultsAll of the 7 patients had symptoms of hyperparathyroidism. Four patients had palpable neck mass. The average serum calcium level of preoperation was 3.07 mmol/L (2.35-4.98 mmol/L). The average parathyroid hormone (PTH) level was 1 181.5 pg/mL (78.4-2 061.7 pg/mL), which elevated 17 times the upper limit of normal. One case had operation in other hospital and six cases in Jishuitan hospital. The tumors located in the left inferior parathyroid gland in 3 cases, 2 cases of right lower parathyroid, and right superior parathyroid gland in 1 cases. One case underwent parathyroidectomy, parathyroidectomy including ipsilateral thyroid lobe or part of it was performed in 5 cases. Of 5 cases, 1 case was added central compartment lymphadenectomy. Three cases of postoperative tumor recurrence underwent reoperation, of which 1 case recurred 3 times. Two cases died. The remining 5 had survived until now, had survived for 5 years in 3 cases. ConclusionsA comprehensive approach with clinical presentation, serum calcium and PTH levels, B-ultrasonography, 99Tcm-MIBI, intraoperation aberrant findings, and histopathology offers help to accurate diagnosis of parathyroid carcinoma. Surgery is en bloc resection of the primary lesion. Recurrence needs reoperation, and long-term follow-up is advised.

  • 甲状腺癌术后再发甲状旁腺癌1例诊治分析并文献复习

    目的探讨甲状旁腺癌的临床诊疗经验。 方法回顾性分析笔者所在医院收治的1例甲状腺癌术后再发甲状旁腺癌病例的临床资料和诊疗经过,并进行文献复习。 结果患者第1次因甲状腺癌行手术治疗,术前甲状旁腺素(PTH)及血钙水平轻度升高,但未见甲状旁腺肿瘤,术后PTH及血钙降至正常水平。患者第2次以颈部肿物、甲状旁腺功能亢进症、高钙血症入院行手术治疗后,PTH及血钙再次降至正常水平,石蜡切片病理标本经专家会诊明确甲状旁腺癌的诊断。第2次术后1年患者的甲状旁腺癌复发,行微创消融治疗,术后PTH及血钙有所下降,但未达理想范围,现仍在随访中。 结论甲状腺癌并发甲状旁腺癌临床罕见,其术前诊断困难,根据术后石蜡病理检查及免疫组化检查可以确诊。手术是其最有效的治疗方法,术后局部复发率较高,故术后应长期监测血钙和血PTH水平,尽早发现肿瘤复发或转移情况,尽早治疗,以求提高生存率和延长无瘤生存期。

  • Refractory recurrent metastatic parathyroid carcinoma: MDT of a case and literatures review

    ObjectiveTo summarize the experience of comprehensive treatment of parathyroid carcinoma (PTC).MethodThe clinicopathologic data of patient with PTC admitted to the First Affiliated Hospital of Kunming Medical University were retrospectively analyzed.ResultsThe patient was a 42-year-old male, who was diagnosed with the primary hyperparathyroidism after suffering from systemic joint pain for more than 2 years. The patient accepted the first operation in a primary hospital, including the resection of the PTC and ipsilateral thyroid lobectomy, and the PTC was confirmed pathologically. The second operation was performed due to the tumor relapse within thyroid bed. The third operation was performed with the palliative resection of the recurrent tumor in the right neck and the three-dimensional conformal radiation therapy was performed. The fourth operation was performed in the left neck with lateral lymph node dissection of level Ⅲ and level Ⅳ. The lower left lung cuneiform resection was performed in the fifth operation. For the last operation, the mediastinal metastatic tumor was removed with thoracoscopy. The multiple imaging evaluation showed no evidence of recurrence in the neck, but the extensive pulmonary metastasis occurred.ConclusionsSurgery is the only effective treatment for PTC. En bloc excision consists of resection of primary tumor, ipsilateral thyroid lobectomy, other surrounding structures involved by the tumor and central neck dissection. During operation, tumor rupture should be avoided. Accessible metastatic tumor should be resected when possible. Radiotherapy should be performed in patient with local infiltration or unresectable tumor. Effect of chemotherapy for PTC is poor. Supportive medical care should be given for fatal hypercalcemia in patient when treatment failed to control tumor.
