Establishment and characterization of human bladder cancer cell lines BexBra1, BexBra2, and BexBra4.

Bladder cancer (BC) is the fourth most common cancer in the USA. In Brazil, BC represents 3% of the total existing carcinomas in the population and represents the second highest incidence among urological tumors. The majority of bladder cancer cell lines available were derived from Caucasians and established in the seventies or eighties.

Incidence of benign lesions according to tumor size in solid renal masses.

Objective: The incidence of solid renal masses has increased sharply in recent years due to widespread use of abdominal imaging studies. The aim of the present study was to evaluate the incidence of benign lesions in solid renal masses according to tumor size.

Materials And Methods: The authors retrospectively reviewed the records of 305 patients with 328 renal solid masses treated by surgery.

An evaluation of the anti-neoplastic activity of curcumin in prostate cancer cell lines.

Objective: The aim of our study is to investigate the anti-neoplastic effect of curcumin in prostate cancer cell lines. Specifically, we are using the LNCaP cell line and another prostate cell line developed in our laboratory, PcBra1. The PcBra1 cells were derived from a localized, obstructive prostate cancer with a Gleason score of 9 (4+5).

Pretreatment tumor volume estimation based on total serum psa in patients with localized prostate cancer.

Objectives: To establish a formula that estimates tumor volume in localized prostate cancer based on serum prostate specific antigen levels. One of the main prognostic variables in localized prostate cancer is tumor volume, which can be precisely defined only after prostate extirpation. The present study defines a simple method that allows for estimation of tumor volume before treatment, which can help to establish a better therapeutic strategy for each patient.
