Background. Neuroendocrine tumors (NETs) are characterized by having behavior and prognosis that depend upon tumor histology, primary site, staging, and proliferative index. The symptoms associated with carcinoid syndrome and vasoactive intestinal peptide tumors are treated with octreotide acetate. The PROMID trial assesses the effect of octreotide LAR on the tumor growth in patients with well-differentiated metastatic midgut NETs. The CLARINET trial evaluates the effects of lanreotide in patients with nonfunctional, well-, or moderately differentiated metastatic enteropancreatic NETs.

INTRODUCTION
CgA and testosterone are two serum markers that may be involved in prostate cancer. The objective of this study was to evaluate the relationship of testosterone and CgA to grades and stages of prostate cancer, particularly whether low-serum testosterone and high-serum CgA are associated with more aggressive grades, and higher pathological stages of the disease.
METHODS:
This perspective study included 121 men (Caucasian only) presenting with -newly-diagnosed, untreated prostate cancer. All the patients underwent radical prostatectomy.
RESULTS:
