目的提高原发性甲状旁腺功能亢进性骨病的早期诊断及治疗效果。方法回顾分析4例骨型原发性甲状旁腺功能亢进症患者的临床资料及随访结果。其中男性2例,女性2例;平均年龄35岁(21~51岁)。临床症状包括疼痛、肿胀,伴有乏力、胃肠不适及体重下降,1例发生病理性骨折,X线表现多发溶骨性病损,核素扫描显示多部位骨骼核素浓聚。实验室检查:血钙:2.23~3.99mmol/L,甲状旁腺素:644~1664pg/ml。全部患者转入头颈部肿瘤外科,手术后确诊甲状旁腺腺瘤3例,甲状旁腺腺癌1例。结果平均随访42个月(8~96个月)。所有患者骨科症状好转,3例术后1.5年骨病损痊愈。甲状旁腺肿瘤无复发及转移。结论早期诊断、及时手术治疗可避免骨型原发性甲状旁腺功能亢进症引起的骨病损加重。除预计可能出现严重的骨相关事件外,骨病损可不作特殊骨科治疗。 相似文献

甲状旁腺肿瘤是引起原发性甲状旁腺亢进症的主要因素。异位甲状旁腺肿瘤较为少见,多数肿瘤无典型的临床症状,隐匿性高而在临床中易被忽视。对异位性肿瘤的定性、定位是目前临床诊治难点,99Tcm-MIBI闪烁扫描术是诊断甲状旁腺肿瘤的金标准,通常与其他影像方法联合应用。手术治疗是最有效也是唯一可以治愈的方式。 相似文献

目的:评价99mTc-甲氧基异丁基异腈(99mTc-MIBI)显像在原发性甲状旁腺功能亢进症(PHPT) 定位诊断中的临床应用价值。方法:回顾性分析57例疑似PHPT患者99mTc-MIBI显像、血清PTH测定及B超检查结果,以术后病理为金标准,对99mTc-MIBI双时相显像、血清PTH测定及B超检查三种诊断方法的灵敏度、特异度、准确度进行比较和评价。结果:术后病理证实,57例患者99mTc-MIBI显像与血清PTH测定两种诊断方法比较,灵敏度、特异度、准确度分别为91.49%(80.85%)、50.00%(80.00%)、84.42%(80.70%);99mTc-MIBI显像与B超检查两种诊断方法比较,灵敏度、特异度、准确度分别为91.49%(76.60%)、50.00%(70.00%)、84.21%(75.44%)。结论:99mTc-MIBI显像对PHPT定位诊断的灵敏度、准确度都高于血清PTH测定及B超检查结果,但特异性较低。99mTc-MIBI显像联合血清PTH测定及B超可以提高PHPT的诊断准确性,具有更高的临床应用价值。 相似文献

Hypercalcemia is associated with a few primary malignant neoplasms and with a variety of tumors that have spread by metastases. Hyperparathyroidism is a diagnosis that is usually not considered in these patients. At our institution, 18 patients with malignant tumors presented over a 6-year period with hypercalcemia caused by hyperparathyroidism. There were five men and 13 women with a mean age of 48 years (range 24-87 years). Primary tumors in these patients included colon carcinoma (four cases), breast carcinoma (four cases), lymphoma (four cases), thyroid carcinoma (four cases), Paget's disease (one case), and lung carcinoma (one case). Metastases of the primary tumor occurred in seven patients, and in 11 patients the tumor was not metastatic or recurrent. Serum levels of calcium, phosphate, and chloride averaged 11.8 mg/dl, and 100 mEq/liter, respectively. C-terminal parathyroid hormone (PTH) levels ranged from 300 to 1,900 pg/ml with an average of 1,150 pg/ml (normal 50-340 pg/ml). At operation, a single parathyroid adenoma was discovered in 15 patients, and four-gland hyperplasia was noted in three patients. In all cases, serum levels of calcium returned to normal after operation. We conclude that patients with malignant tumors and concomitant hypercalcemia should be evaluated for the possibility of hyperparathyroidism. In cases of primary hyperparathyroidism, elevated C-terminal PTH level should be diagnostic. If hyperparathyroidism is determined to be the cause of hypercalcemia, neck exploration and parathyroidectomy are indicated. 相似文献

We report a case of primary hyperparathyroidism associated with a malignant lymphoma in the thyroid gland. A 68-year-old woman
was admitted to hospital with a cervical mass. Ultrasound and computed tomography (CT) revealed a hypoechoic, multinodular
tumor in the left thyroid gland. A gallium-67 citrate scintigram revealed intense radioisotope uptake in the thyroid tumor.
Histological examination of biopsy specimens indicated that this tumor was a large B-cell lymphoma. The coexistence of parathyroid
adenoma in this patient was revealed by a sestamibi scintigram, performed prior to chemotherapy. Following the complete remission
of the lymphoma by chemotherapy, we carried out an excision of the single parathyroid adenoma. To our knowledge, this is the
first report to describe a malignant thyroid lymphoma associated with primary hyperparathyroidism. 相似文献

Primary hyperparathyroidism, most commonly due to a solitary parathyroid adenoma, has become an increasingly diagnosed condition and is one with great potential for cure following appropriate surgical intervention. Functional imaging with Tc-99m-based radiopharmaceuticals has contributed significantly to increased success in preoperative adenoma localization but the advent of fusion of this functional information with anatomical details obtained with computed tomographic imaging has yielded a potentially more powerful clinical tool and one that is particularly well suited to ectopic adenomas and cases of prior failed surgery. Aspects of this modality are discussed with reference to software- and hardware-based fusion techniques and evidence for efficacy. The allied technique of PET/computed tomography is also discussed. 相似文献

Pancreatic cancer is the fourth leading cause of cancer death in both men and women with a mortality: incidence ratio of 0.99.
In an effort to describe the role of clinical features at initial presentation, we conducted a retrospective observational
study in patients with a biopsy-proven diagnosis of adenocarcinoma of the pancreas. Between 1986 and 2001, 308 patients (160
males, 148 females) were diagnosed with pancreatic adenocarcinoma. The mean age at diagnosis was 70.1 yr (range: 34–96 yr).
The mean survival was 7.6 mo (range: 0–97 mo). Statistical analysis was performed using log-rank tests and analysis of variance.
As expected, age at diagnosis was a significant factor affecting survival, with older patients doing relatively poorly (p<0.05). Patients with a good performance status performed significantly better than those with a poor performance status (p<0.01). In addition, the presence of the tumor in the head of the pancreas was a predictor for improved survival (p<0.01). Although smoking increased the chances of detection at an earlier age, neither diabetes mellitus nor a positive smoking
history had a statistically significant effect on the survival. Pancreatic adenocarcinoma is a disease of the elderly associated
with a poorer outcome. Knowledge of possible clinical predictors of survival may lead to better patient counseling regarding
prognosis. 相似文献

In the Western world, primary hyperparathyroidism is now a relatively common disorder that is diagnosed in 0.7% of the general population and in 2% of postmenopausal women. Although patients today typically present with less severe manifestations of disease, the evaluation and management of patients with parathyroid disease remains challenging. Primary hyperparathyroidism is a complex disease process that requires careful diagnosis and thoughtful medical and surgical management. The surgical management of patients with persistent or recurrent disease, inherited primary hyperparathyroidism syndromes, and parathyroid carcinoma is particularly challenging. High‐quality imaging and reliable intraoperative adjuncts are critical to success. Cancer 2014;120:3602–3616 . © 2014 American Cancer Society. 相似文献

Sestamibi scan-directed unilateral neck exploration for primary hyperparathyroidism due to a solitary adenoma 总被引:4,自引:0,他引:4
AIM: To evaluate the accuracy of Tc-99m sestamibi scintography in pre-operative localization of a single parathyroid adenoma and to determine if neck exploration can be limited to the side of the adenoma. METHODS: Over a period of 4 years, 30 patients with primary hyperparathyroid disease underwent surgical treatment in the form of unilateral neck exploration after localization by Tc-99m sestamibi scintigraphy. The scan findings were interpreted by one radiologist with a special interest in parathyroid imaging and the operative findings were correlated with scan findings. RESULTS: Tc-99 sestamibi scan localized a single parathyroid adenoma in 29 patients. There was doubtful uptake of isotope in one patient. Unilateral cervical exploration confirmed isotope scan findings in 29 patients with a positive scan, and these were subsequently proven by histology. In the patient with doubtful sestamibi scan, bilateral neck exploration was undertaken and three enlarged glands were excised. All the three glands were reported to be abnormal, consistent with either adenomas or hyperplasia. All the patients were normocalcaemic after 6 months follow-up. CONCLUSIONS: Our results demonstrate that Tc-99m sestamibi scintigraphy is highly accurate in pre-operative localization of a single parathyroid adenoma when performed by an experienced radiologist. Unilateral cervical exploration, as directed by a positive Tc-99m sestamibi scintigram, seems to be a logical approach for the patients with primary hyperparathyroid disease due to solitary adenoma. 相似文献
