PAPILLARY THYROID CARCINOMA WITH COEXISTENCE OF HASHIMOTO AND TUMOR-ASSOCIATED LYMPHOCYTES
Abstract
https://doi.org/10.31386/dmj.2025.19.2.4
Background: Papillary thyroid carcinoma represents the most common thyroid cancer. The
co-existence of Hashimoto thyroiditis and papillary thyroid carcinoma has long been described
in clinical research; however, the relationship is still debatable. This study aimed to estimate
the coexistence of Hashimoto's thyroiditis and papillary thyroid carcinoma and to correlate
these two conditions with the expression of immunological markers, including CD19 and IgG4,
and with clinicopathological factors.
Methods: The research conducted a retrospective investigation evaluating thyroid tissue
obtained from papillary thyroid carcinoma patients with Hashimoto thyroiditis or tumor-
associated lymphocytes coexistence. The examination determined B-cell and plasma cell
infiltration using CD19 and immunoglobulin G4 markers to correlate them statistically with
demographic and clinicopathological variables.
Results: Showed coexistence of Hashimoto thyroiditis and tumor-associated lymphocytes with
papillary thyroid carcinoma in 74%. A significant association between immunoglobulin G4-
related disease and age was detected in patients below 45 years, particularly among those with
Hashimoto thyroiditis (P=0.039), and with the histological subtypes in patients with classic
variant (66.7% in Hashimoto thyroiditis and 20% in tumor-associated lymphocytes) (P=0.049).
In contrast, other clinicopathological findings showed no correlation to Hashimoto thyroiditis
and immunological markers.
Conclusions: The high percentage of the coexistence of Hashimoto thyroiditis with papillary
thyroid carcinoma, together with the predominance of immunoglobulin G4-related disease in
young age patients, draws attention to immunobiological mechanisms behind this cancer,
which might help in the development of modern-immune-based diagnostic and therapeutic
approaches.
