Is thyroid hormone transport disturbed in erythrocytes from patients with chronic renal failure on hemodialysis?
Despite the fact that uremic patients on hemodialysis show low serum levels of LT3, changes in LT3 influx and efflux could act as a compensatory mechanism that neutralize thyroid hormone dysfunction in order to maintain the euthyroid state.
CEA is useful in the preoperative evaluation of patients with hepatic colorectal metastases for assessing prognosis and is complimentary to history and physical examination in the diagnosis of liver metastases. Patients with colorectal liver metastases and preoperative CEA<or =30 ng/mL are more likely to be resectable, and they have the longest survival.
