Correlation between the complex PSA/total PSA ratio and the free PSA/total PSA ratio, sensitivity and specificity of both markers for the diagnosis of prostate cancer.

Objective: To compare the behaviour of the PSAcomplex/PSAtotal percentage (PSAc%) against the PSA free/PSA total (PSAl%) and analyse both markers for their usefulness in diagnosing prostate cancer.

Material And Methods: We measured total PSA (PSAt), free PSA (PSAl), complex PSA (PSAc), PSAl% and PSAc% levels in 158 patients. Of these, 98 (62%) were biopsied for presenting PSAt≥3 ng/dl and PSAl%<20, PSAt>10, suspicious rectal examination or suspicious ultrasound node.

[Usefulness of the determination of thyroglobulin in lymph node aspirates of patients with papillary thyroid carcinoma and positive antithyroglobulin antibodies].

Objective: We wanted to study the utility of thyroglobulin determination in the washout of fine needle aspiration (FNAB-Tg) of lymph metastatic nodes in patients with papillar thyroid carcinoma (PTC) and positive serum thyroglobulin antibodies (AbTg).

Materials And Methods: We have studied 11 patients (49.9+/-11.
