The differentiated thyroid cancer is the most common endocrine tumour, whose incidence has increased faster today than any other malignancy. Papillary thyroid carcinoma is the most common form of differentiated thyroid cancer and represents 90% of cases, with the average age at diagnosis of 45 years. There is not much information on the occupational risk of thyroid cancer literature, probably due to the low incidence of this tumour.
Objective Identify cases of thyroid cancer diagnosed in workers at a Hospital in Spain during the period 2010-2015 and to establish whether there is excess cases.
Material and method For each case, occurred during the period 2010-2015, it has analysed: date of birth, gender, employment status, service/unit and work history in the hospital, location and size of the tumour, date of diagnosis of neoplasia, type histological of neoplasia, risk factors (BMI, tobacco). We calculated the standardised incidence ratio (SIR) for thyroid cancer.
Results There have been six thyroid neoplasms, which were diagnostic in women, with an average age at diagnosis of 47 one year. The rates were histologically papillary neoplasm (66.6%) and follicular (33.3%) carcinoma. The average tumour size was 3.25 mm. We had 2 cases in nurses, 2 cases in technical assistant, 1 case a psychologist and 1 was detected in an administrative.
Conclusions It has detected an excess risk of cancer in the group studied. The few studies found establish a relationship, but not consistently; among health workers not exposed to ionising radiation and increased risk of thyroid cancer. The difficulty in obtaining information on people at risk and raises the incidence of cases improved information sources for this type of study in Spain.
