Histologic grading study of prostate adenocarcinoma: The development of a new system and comparison with other methods—A preliminary study Open
A new grading system for adenocarcinoma of the prostate (MDAH System) and its simplified version, both based on the percentage of tumor that is differentiated (gland-forming) or undifferentiated (non-gland-forming), were compared with the …

Salvage cystectomy for bladder carcinoma Open
Sixty-two patients with carcinoma of the bladder who had received external radiation as definitive therapy underwent radical cystectomy for persistent or recurrent tumor. A preoperative clinical assessment correctly predicted whether the t…
