Abstract:
Objective Exploration of TSH, FT3, FT4 changes in critical condition prior to death.Methods 84 patients that were anti-tumor therapy acceptable and not associated with the treatment of thyroid disease in patients with terminal tumors. Age from 24 to 85-year-old, male 56, female 28. The use of SELDI technology (surface-enhanced laser description / ionization time-of-flight mass spectrometry protein chip technology) checks to M/Z for the 11 100 + H～11 900 + H peak of the cluster, divided into the positive group for critically ill patients with early warning protein (LGT) and the negative group for it. All patients were given TSH, FT3, FT4 inspection. The results were statistically analyzed. Results TSH, FT3, FT4 in the LGT positive group was significantly lower than in the negative LGT group. There was no correlation between TSH,FT3 and FT4 in the LGT positive group;In the negative LGT group FT3 and FT4 had a positive correlation,and FT3 and TSH no relevance. Conclusion Thyroid function is normal in the stage of cancer patients stable condition. Possible pituitary-hypothyroidism may occur as the disease advances to the end or before death.This may be an important factor causing the acceleration to the death of the patients. However, the cause and effect between this phenomenon and the early warning of protein fingerprint group(LGT) is still not clear. In critical condition checking thyroid function and render supplementary amount of thyroid hormone in accordance with the checking results may be beneficial.
