Chromosomal analysis of bladder cancer. II. A practical method.
Twenty-seven successive bladder cancer tissue specimens, varying from noninfiltrating to deeply infiltrating ones, were chromosomally analyzed using a new direct method. Recognizable metaphases were obtained from 25 specimens (93%). In nearly all cases, suitable C-banding and in nine cases G-banding was achieved. Essential steps in this method are colcemid application in two steps, interrupted by washing with Hanks' balanced sodium solution and two separated hypotonic treatments. This method is easy to use and not time consuming.
