Introduction: Papillary carcinoma is the most common form of well-differentiated thyroid cancer (80% of the total). In recent years there has been a significant progressive increase in prevalence.

Objectives: The aim of the study was to evaluate the clinical characteristics of the newly diagnosed papillary thyroid carcinoma at the Sanitary Area of Jerez, as well as to analyze its incidence in recent years.

Material and Methods: An observational, descriptive and retrospective study of patients diagnosed with papillary thyroid carcinoma in the Health Management Area of Jerez during a 3 year period (2017–2019). Epidemiological and clinical characteristics were analysed and The American Thyroid Association (ATA) classification was used for initial risk classification.

Results: During the study period, a total of 63 patients with papillary thyroid carcinoma were diagnosed: 26 in 2017 (5.83/100,000 inhabitants/year); 20 in 2018 (4.48/100,000 inhabitants/year) and 17 (3.81/100,000 inhabitants/year) in 2019. Of these, 5 cases (7.93%) were microcarcinomas. 74% were women with a mean age at diagnosis of 48.89 ± 14 years. 31% of the patients were obese and 28.8% were overweight. The health area was identified: 47.6% area of Jerez, 44.4% area of Jerez-Sierra and 6.3% of Jerez-Costa. 20.6% were smokers. Regarding the clinical characteristics, 50.8% were symptomatic with a 76.2% of single nodules and an average size of 19.8 ± 10 mm. After surgery, based on the 2015 ATA risk classification, 50.6% were low, 27% were intermediate and 12.7% were classified as hig risk of recurrence. Postoperative RAI ablation was used in 81% of patients.

Conclusions: In our area we found an incidence of papillary thyroid cancer similar to other published series. In most cases the diagnosis is made in early stages.
