BACKGROUND
Various staging systems for thyroid cancer that focus on cancer specific death have been suggested, but this approach had a limitation due to the relatively long clinical course and very low rate of cancer death. This study was performed to evaluate the staging systems and to determine the most predictive staging system for predicting recurrence. METHODS: The patients who underwent first total or near total thyroidectomy due to papillary thyroid cancer (PTC) at Asan Medical Center between January 1995 and December 2001 were the subjects of this study. The commonly used 8 staging systems were applied to these subjects. Disease free survival (DFS) and the relative importance of each staging system were determined by the Kaplan-Meier method, the Cox-proportional hazards model and the proportion of variation in the survival time explained (PVE). RESULTS: A total of 952 patients (M = 117, F = 835) were enrolled and their mean age was 45 years. During a median of 10 years of follow-up, 146 (15.3%) of 952 patients had recurred tumor. The independent prognostic factors were male gender, tumor size, extrathyroidal invasion and cervical lymph node metastasis. Risk stratification according to the American thyroid association (ATA) guideline was the most predictive staging system for recurrence of PTC (PVE 88.6%). The staging systems from EORTC (PVE 79.5%), and MACIS (PVE 68.4%) had significant values for predicting recurrence of PTC. The stage of NTCTCS could not predict recurrence (PVE 4.5%, P = 0.11). CONCLUSION: Risk stratification according to the ATA was most predictive staging system for predicting recurrence of PTC. The MACIS and EORTC staging systems have good value for predicting recurrence of PTC.

AbstractAbstract PDF
BACKGROUND
The incidence of thyroid cancer is rapidly increasing. The aim of this study is to examine time trends in the characteristics of thyroid cancer and to determine the cause of the increase of thyroid cancer. METHODS: We evaluated 4,646 patients that underwent surgery at the Asan Medical Center for thyroid cancer between 1995 and 2006. Patients were evaluated concerning the histology, size of the primary tumor, sex, and age at the time of surgery. RESULTS: Surgically treated case of thyroid cancer increased from 91 in 1995 to 960 in 2006-a 10.5-fold increase during the 12-year period. Based on the histological categories, the proportion of papillary thyroid carcinomas (PTCs) increased from 79.1% to 94.5% during the 12-year period. According to the primary tumor size in the PTCs, the proportion of PTCs measuring 1 cm or smaller increased from 14% to 56% during the 12-year period. Whereas the proportion of PTCs measuring from 1 cm to 2 cm were similar (between 31% and 41% during the 12-year period), the proportion of PTC measuring from 2 cm to 4 cm decreased from 51% to 11% during the 12-year period. Thyroid cancer affected women more often than men by a ratio of 3.7. PTC was most common in patients in their forties, especially among women. CONCLUSIONS: The increasing number of surgically treated cases of thyroid cancer is predominantly due to an increase of papillary thyroid cancer measuring 1 cm or less. These trends suggest that the increase in surgically treated cases of thyroid cancer reflects increased detection of occult thyroid cancer due to advances in medical surveillance of impalpable nodules rather than a true increase in the number of thyroid cancers.
