Incidental Thyroid Carcinoma Diagnosed after Total Thyroidectomy for Benign Thyroid Diseases: Incidence and Association with Thyroid Disease Type and Laboratory Markers

Table 4

(a) Biochemical markers (expressed as median values and interquartile range) in the subgroups of patients with TC alone and TC + CLT.

	TC alone	TC + CLT	𝑃 value
TgAbs (ng/mL)	14.70 (11.75–27.68)	53.65 (25.96–91.66)	0.039
TPOAbs (U/mL)	6.25 (2.00–15.97)	103.90 (25.91–172.40)	0.011
Tg (ng/mL)	92.35 (20.75–497.50)	47.00 (17.67–132.75)	0.287
Age (years)	47.00 (34.50–60.50)	56.50 (40.50–65.50)	0.250

TC: thyroid cancer; CLT: chronic lymphocytic thyroiditis; 𝑃 value, Mann-Whitney U-test.

(b) Biochemical markers (expressed as median values and interquartile range) in the subgroups CLT alone and TC + CLT.

	CLT alone	TC + CLT	𝑃 value
TgAbs (ng/mL)	105.40 (23.00–400.60)	53.65 (25.96–91.66)	0.341
TPOAbs (U/mL)	75.62 (13.21–495.84)	103.90 (25.91–172.40)	0.826
Tg (ng/mL)	42.15 (13.01–83.65)	47.00 (17.67–132.75)	0.749
Age (years)	46.00 (37.50–57.00)	56.50 (40.50–65.50)	0.320

TC: thyroid cancer, CLT: chronic lymphocytic thyroiditis; 𝑃 value, Mann-Whitney U-test.
