He and his associates hypothesized that a pelvic tumor that has invaded the bladder might shed malignant cells that could be detected by microscopic examination of the urine, in much the same way that peritoneal "washes" are examined for the microscopic spread of ovarian or other cancers.
In a retrospective study using databases at two medical centers, the researchers reviewed the findings on urine samples collected from 93 women with pelvic cancer (mean age 48 years) who were treated between 1999 and 2004.
