Molecular analysis of cells from urine provides a convenient approach to
non-invasive detection of bladder cancer. The practical use of urinary cell-based
tests is often hampered by difficulties in handling and analyzing large sample
volumes, the need for rapid sample processing to avoid degradation of cellular
content, and low sensitivity due to a high background of normal cells. We present
a filtration device, designed for home or point-of-care use, which enables
collection, storage and shipment of urinary cells. A special feature of this
device is a removable cartridge housing a membrane filter, which after filtration
of urine can be transferred to a storage unit containing an appropriate
preserving solution. In spiking experiments, the use of this device provided
efficient recovery of bladder cancer cells with elimination of >99% of excess
smaller-sized cells. The performance of the device was further evaluated by
DNA-based analysis of urinary cells collected from 57 patients subjected to
transurethral resection following flexible cystoscopy indicating the presence of
a tumor. All samples were tested for FGFR3 mutations and seven DNA methylation
markers (BCL2, CCNA1, EOMES, HOXA9, POU4F2, SALL3 and VIM). In the group of
patients where a transitional cell tumor was confirmed at histopathological
evaluation, urine DNA was positive for one or more markers in 29 out of 31 cases
(94%), including 19 with FGFR3 mutation (61%). In the group of patients with
benign histopathology, urine DNA was positive for methylation markers in 13 out
of 26 cases (50%). Only one patient in this group was positive for a FGFR3
mutation. This patient had a stage Ta tumor resected 6 months later. The ability
to easily collect, store and ship diagnostic cells from urine using the presented
device may facilitate non-invasive testing for bladder cancer.
