Abstract
Objective Thyroid carcinoma (TC) is the most common endocrine tumor in the human body. Papillary thyroid carcinoma (PTC) accounts for more than 80% of thyroid cancers. Accurate prediction of elderly PTC can help reduce the mortality of patients. We aimed to construct a nomogram predicting cancer-specific survival (CSS) in elderly patients with PTC. Methods Patient information was downloaded from the Surveillance, Epidemiology, and End Results (SEER) program. Univariate and multivariate Cox regression models were used to screen the independent risk factors for patients with PTC. The nomogram of elderly patients with PTC was constructed based on the multivariate Cox regression model. We used the concordance index (C-index), the area under the receiver operating characteristic curve (AUC) and the calibration curve to test the accuracy and discrimination of the prediction model. Decision curve analysis (DCA) was used to test the clinical value of the model. Results A total of 14,138 elderly patients with PTC were included in this study. Patients from 2004 to 2015 were randomly divided into a training set (N = 7379) and a validation set (N = 3141), and data from 2016 to 2018 were divided into an external validation set (N = 3618). Proportional sub-distribution hazard model showed that age, sex, tumor size, histological grade, TNM stage, surgery and chemotherapy were independent risk factors for prognosis. In the training set, validation set and external validation set, the C-index was 0.87(95%CI: 0.852–0.888), 0.891(95%CI: 0.866–0.916) and 0.931(95%CI:0.894–0.968), respectively, indicating that the nomogram had good discrimination. Calibration curves and AUC suggest that the prediction model has good discrimination and accuracy. Conclusions We constructed a new nomogram to predict CSS in elderly patients with PTC. Internal cross-validation and external validation indicate that the model has good discrimination and accuracy. The predictive model can help doctors and patients make clinical decisions.

Clinicopathological features of thyroid cancer in the elderly compared to younger counterparts: single-center experience. J Endocrinol Invest 2017; 40:471-479. [PMID: 27885512 DOI: 10.1007/s40618-016-0577-7] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/12/2016] [Accepted: 11/02/2016] [Indexed: 12/17/2022]
Abstract
PURPOSE The incidence of thyroid cancer is increased in elderly patients. It tends to be larger and have more aggressive characteristics in these patients. Our aim was to compare features of thyroid carcinoma in geriatric and non-geriatric patients. METHODS In total, 933 patients with thyroid cancer were retrospectively reviewed. Thyroid functions, ultrasonography features of malignant nodules, cytological and histopathological findings and the rates of recurrence and persistence were compared in patients ≥65 and <65 years old. RESULTS There were 153 malignant foci in 109 (11.7%) patients ≥65 and 1185 malignant foci in 824 (88.3%) patients <65 years old. Mean nodule diameter was significantly higher in geriatric patients (p = 0.008). Most of the ultrasonographical features of malignant nodules were similar in two groups. Hypoechoic halo was observed in 16.4 and 28.6% of malignant nodules in geriatric and non-geriatric group, respectively (p = 0.034). There was no significant difference in cytological diagnosis. Histopathologically, tumor diameter, rates of microcarcinomas and incidentality were similar. Of all cancer types, 88.8% in geriatric and 93.9% in non-geriatric group were papillary thyroid cancer (p = 0.028). Hurthle cell cancer constituted 3.9 and 1.1% of carcinomas in geriatric and non-geriatric patients, respectively (p = 0.015); 2.0 and 0.2% of tumors in geriatric and non-geriatric group were anaplastic, respectively (p = 0.012). Capsular and vascular invasion, extrathyroidal extension, persistence and recurrence rates were similar. CONCLUSIONS Rates of anaplastic cancer and Hurthle cell cancer which is known to have worser prognosis among other differentiated thyroid cancers are increased in geriatric ages. Cytological evaluation of thyroid nodules should strongly be considered due to increased tendency for aggressive tumor types in these patients.
