[Clinical significance of peptide hormones LH, FSH, TSH, prolactin, HCG, parathormone, calcitonin and prostaglandin F2 alpha in kidney neoplasms].

: Peptide hormones LH, FSH, TSH, e-peptide, prolactin, HCG, PTH, calcitonin and prostaglandin F2 alpha were evaluated in 25 patients with renal adenocancer. Prolactin elevation found in 45% was unrelated to the stage of the disease, while aberrant TSH and FSH were more sensitive in indicating distant metastasis. Prostaglandin F2 alpha, measured as a stable degradation product 13,14-DHK-PGF2 alpha, was frequently elevated and normalized following tumor nephrectomy within 12 month. Serum PTH was decreased in patients with tumor dissemination suggesting resorptive hypercalcemina, whereas none of the patient had circulating HCG levels. Therefore even patients without any paraneoplastic syndromes have a frequent change of peptide hormones directly or indirectly caused by renal cancer.
