Free T3, Free T4, TSH, anti-thyroglobulin antibody and thyroid peroxidase antibody were evaluated prior and after 6 cycles of treatment with chemotherapy.

Results: There were highly statistically significant difference in TSH p=0.005 being higher after chemotherapy, also in free T4 values P=0.025 being lower after chemotherapy. There was no statistically significant difference in free T3 P=0.051, Concerning both anti-thyroglobulin and anti-peroxidase there was no change in values before and after chemotherapy.
