Abstract


Introduction: For many years much attention has been focused on an interaction between the breast disease and the thyroid gland function in the literature. In those studies the question whether disease changes in the thyroid gland can induces the breast disease was addressed. On the other hand there are a few works concerning the inverted question whether the breast cancer therapy, in particular after mastectomy and chemotherapy, can disturb the thyroid gland function. The aim of the study is to investigate the influence of the mastectomy and chemotherapy on the thyroid gland function in women after breast cancer therapy.
Material and methods: 173 patients aged 30-80 (average 56) were included in this study. The studied group comprised 97 women after breast cancer therapy (average age 60). The control group consisted of 76 patients (average age 55). 75 patients after mastectomy of the studied group were additionally treated with chemotherapy, but in 22 women chemotherapy was not applied. The following methods were used to carry out the research: the USG method was applied to evaluate thyroid morphological condition in women after mastectomy and chemotherapy; the color Doppler technique was used for dynamic presentation and fine- needle aspiration biopsy: examination of the thyroid functional state by measuring the TSH, fT3, fT4 hormone concentration and the level of antithyroid antibodies.
Results: An average concentration of antithyroid antibodies: anti-TPO and anti-Tg was found significantly higher in the studied group of women after chemotherapy, comparing with the control group. The level of fT3 hormone concentration was comparable in all investigated groups. Nevertheless, the average concentration of TSH was found higher in women after mastectomy and chemotherapy and as a consequence leading to hypothyroidism.
Conclusion: Taking into consideration the high level of the concentration of antithyroid antibodies: (anty-TPO and anty- Tg), which lead to destruction of the thyroid gland tissue, the thyroid gland function of the women after mastectomy and chemotherapy should be monitored morphologically as well as functionally.
