Retroperitoneoscopic nephrectomy in benign pathology.

Introduction: We report our experience with 43 retroperitoneal laparoscopic nephrectomy for benign kidney disease.

Materials And Methods: All patients had a poor function from obstructive uropathology and renal atrophy. None of these patients had a previous lumbotomy.

Pretreatment p53 nuclear overexpression as a prognostic marker in superficial bladder cancer treated with Bacillus Calmette-Guérin (BCG).

Introduction: Altered p53 gene product correlates with the stage and grade of bladder tumor, but its value as a predictor of BCG response has been disappointing. In order to revisit the prognostic value of pretreatment p53 nuclear overexpression for the BCG response, we studied a large cohort of consecutive patients with superficial bladder cancer treated with BCG.

Methods: From 1988 to 2001, 102 patients with a history of multifocal, recurrent, and/or high-risk papillary transitional cell carcinoma or carcinoma in situ, were treated for the first time with BCG.

Do prognostic parameters of remission versus relapse after Bacillus Calmette-Guérin (BCG) immunotherapy exist?. analysis of a quarter century of literature.

Objective: To review prognostic factors identified in clinical trials for remission versus relapse after intravesical adjuvant Bacillus Calmette-Guérin (BCG) immunotherapy for superficial bladder cancer (Ta, T1, and carcinoma in situ).

Materials And Methods: Information was retrieved by a MEDLINE search of the English literature. Indexing terms comprised bladder cancer, bladder neoplasm, BCG vaccine, superficial bladder cancer, immunotherapy, intravesical therapy, prognostic marker, and Bacillus Calmette-Guérin.
