Incidence Trends for Papillary Thyroid Carcinoma and Their Correlation with Thyroid Surgery and Thyroid Fine-Needle Aspirate Cytology

Abstract

These results suggest increasing PTC incidence is largely attributable to greater diagnosis of small PTC, many of which are likely to have been asymptomatic, identified by neck ultrasonography and subsequent FNAB. However, the incidence of PTC larger than 1 cm in patients without history of preoperative FNAB has also risen, suggesting the occurrence of clinically relevant tumors may also have increased.

An Epidemiological Analysis of Thyroid Cancer in a Spanish Population: Presentation, Incidence and Survival

“…Although the incidence of MPTC is increasing in our population, also an increase in the incidence of tumours greater than 1 cm (Papillary non MPTC) was evident in both sexes. Similar findings have been reported in studies performed by Burgess in Australia (Burgess, 2002;Burgess & Tucker 2006). We also observed an increase in the ratio of total thyroidectomy for other kind of thyroidectomy over time.…”

Annual report to the nation on the status of cancer, 1975–2003, featuring cancer among U.S. Hispanic/Latino populations

“…Increases are observed in all U.S. racial and ethnic populations and all age groups, as well as globally. [50][51][52][53][54] Although not in the top 15 causes of death, long-term thyroid cancer death rate trends decreased in men from 1975 to 1983 and in women from 1975 to 1988. They have increased in men from 1983 through 2003 and have been stable in women from 1988 to 2003.…”

“…13 Changes in diagnostic procedures, including the introduction and greater use of ultrasonography and fine-needle aspiration biopsy, likely contribute to the incidence increase. 50,51,55,56 Radiation exposure in childhood and adolescence is also a recognized risk factor. 57,58 More research on the relation among temporal trends, diagnostic procedures, and exposure to radiation and other potential risk factors is needed.…”

Role of fine needle aspiration cytology in the diagnosis of papillary carcinoma thyroid: A retrospective study from north-east India

“…[1,2] About 75-85% of thyroid cancers are papillary thyroid carcinoma (PTC) making it the most common malignant tumor among all thyroid cancers. [3,4] It is even more commonly seen in the North-East sub-Himalayan India.…”
