Serum levels of the peptide hormones, LH, FSH, TSH, prolactin, beta-HCG and PTH are observed to significantly modulate in patients with urogenital tumors, beta-HCG appears elevated in patients with chorioncarcinoma, teratoma and embryonal carcinoma and is shown to increase serum prolactin. TSH and prolactin are measured in pathological range in patients with renal carcinomas. Following nephrectomy serum TSH persists in high levels only in patients with advanced diseases, while PTH is more frequently suppressed in these patients. Serum LH and prolactin show a more distinct change of values in infiltrating bladder cancer, when compared to that of noninvasive bladder carcinomas. Prostate benign hyperplasia and cancer demonstrate similar ranges for peptide hormones, that will be changed by estrogen treatment in its LH, TSH and prolactin pattern. Serum levels of peptide hormones are affected by a complex system of ectopic hormone production, synthesis of peptide analogues, metabolic changes due to age and treatment.

Prostaglandin F2 alpha can be measured as a stable degradation product, 13,14-dihydro-15-keto-prostaglandin F2 alpha (DHK-PGF2 alpha). Pathological serum levels of this lipid compound have been observed in prostate hyperplasia and treated testicular cancer patients. In renal cancer patients elevated DHK-PGF2 alpha shows a trend to normalize 12 months following nephrectomy in stage T0N0M0. Bladder cancer patients have slightly increased DHK-PGF2 alpha that differ in relation to preinvasive bladder cancer. In contrast serum haptoglobin levels were significantly pathological in patients with kidney and bladder cancer, suggesting involved cancer metabolism. Patients with prostate and testis cancer are without distinct relation to the tumour stage. After specification of haptoglobin types no coincidence to urogenital tumours could be detected. Correlated aberration of PGF2 alpha and haptoglobin displayed different patterns depending on the type of urogenital tumour.
