Thyroid Cancer in the Pediatric Age in Sicily: Influence of the Volcanic Environment.
2017
Background/Aim: Pediatric thyroid cancer (TC) is rare but its incidence is increasing. We analyzed incidence and characteristics of pediatric TC in Sicily and comparatively evaluated data from the volcanic and non-volcanic areas. Materials and Methods: All incident pediatric (0-19 years) TCs in Sicily between 2002-2009 were analyzed for the area of residence and compared to data for adults. Results: A total of 54 differentiated TCs (DTC) and nine medullary TCs were diagnosed in Sicily in children between 2002-2009. DTC age standardized rate for the world population (ASRw) was 0.8/105 in females and 0.2/105 in males, with a higher incidence in the volcanic area (ASRw=1.4/105 in females, 0.5/…
Anaplastic Thyroid Cancer in Sicily: The Role of Environmental Characteristics
2017
Background: Anaplastic thyroid cancer (ATC) is a rare but extremely aggressive cancer of the thyroid, contributing up to 30-40% of thyroid cancer-specific mortality. We analyzed ATC characteristics and survival rates in Sicily to evaluate the possible influence of environmental factors. With this aim data regarding ATC incidences in urban/rural and industrial, iodine deficient and volcanic vs. control areas were compared in Sicily as well as ATC data from Sicily and USA. Methods: Using the Sicilian Register of Thyroid Cancer (SRTC) database incidence, age, gender, tumor size and histotype, extrathyroidal extension, stage and coexistence with pre-existing differentiated thyroid cancer (DTC) …
