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.

[Prognostic value of E-cadherina, beta catenin, Ki-67 antigen and p53 protein in the superficial bladder tumors].

Introduction: The natural history of the superficial carcinoma of bladder is characterized by his high rate of recurrence and by the aptitude to progress to higher stages. We are going to investigate the capacity of prediction for tumor recurrence of protein p53, antigen Ki-67, E Cadherin and Beta Catenin

Material And Method: 88 T1 tumors with a median of free time of disease of 36 months. 58% of the serie has received prophylactic treatment with BCG 81 mg.
