Introduction: The association between papillary thyroid carcinoma and thyroiditis was first reported in 1955 by Daily, in 2023 if this association is well established, it still continues to be talked about. Does cancer precede thyroiditis or does thyroiditis induce cancer and when the two combine does cancer have a better prognosis?
Material and methods: We report a prospective study carried out in a hospital center in Algeria between 2020 and 2022 which included 267 papillary thyroid cancers, of which 97 (36.3%) of the patients had thyroiditis. 85 (87.6%) of the patients who had an association with thyroiditis were women with a sex ratio of 3.29; their average age was 42.79 +/- 1.16 years. In a situation of thyroiditis, the tumor size was smaller (OR 0.51), with less vascular invasion (OR 0.39) but more multifocality (OR 1.75) compared to patients who didnt have thyroiditis.
Discussion: The association of papillary thyroid cancer with thyroiditis has generated many studies around the world, however its difficult to make comparisons between them because of their heterogeneity; however, our study seems to agree with the results obtained by a majority of studies already published.
Conclusion: In our study, the association of papillary thyroid cancer with thyroiditis seems to be a better prognostic factor.
