Patent CA-2770277-A1 (CA)
Inventor: TATLOW DEAN D
IPC: A61M25/04
Filed: 2012-03-02
Abstract: A medical catheter inserted into a body cavity for drainage of fluid. The catheter comprises flexible fibers/filaments that form a plurality of channels for movement of fluid. These fibers/filaments are located around a central inflation device contained within a flexible tubular catheter, composed of two parts. The outer sleeve and inner sleeve form a tubular catheter joined by a flexible connector that interlocks the sleeves during insertion. Once inserted the connection between the two sleeves is released, enabling the outer sleeve to move over top of the inner sleeve revealing fibers/filaments for fluid drainage. An inflatable retention balloon contained within the fibers/filaments secures the catheter in the bladder once inflated. This arrangement allows insertion of non-contaminated fibers/filaments into the body cavity. Insertion of these fibers/filaments creates a more complete drainage of fluid, decreased risk of bacterial infection, reduction of blockage, and improved patient comfort.

Abstract: Purpose. The relationship between inherited genetic variations in 5a-reductase type 1 (SRD5A1) and type 2 (SRD5A2) genes and the risk of biochemical recurrence after radical prostatectomy (RP) in prostate cancer (PCa) remains a fairly unexplored area of research. Patients and Methods. We studied 526 men with organ-confined and locally advanced PCa with a median follow-up time of 7.4 years. We investigated the effects of allelic variants of SRD5A1 and SRD5A2 genes and haplotype-tagging single nucleotide polymorphisms (htSNPs; n=19) on recurrence-free survival after RP using Kaplan-Meier plots, the log-rank test, and Cox proportional hazard models. Results. Upon adjusting for known prognostic clinical and pathological factors, eight htSNPs were shown to be independent predictors of recurrence. The SRD5A1 rs 166050 polymorphism was associated with an increased recurrence risk of HR=1.83 (95% CI, 1.04-3.21; P=0.035), while the rs518673 in SRD5A1 was associated with a decreased risk (HR=0.59, 95% CI, 0.41-0.85; P=0.004). The SRD5A2 gene was strongly associated with the risk of relapse with six polymorphisms being positively associated with recurrence including the known SRD5A2 V89L (rs523349) (HR=2.14, 95% CI, 1.23-3.70; P=0.007) and a protective htSNP rs12470143 with a HR of 0.66, (95% CI, 0.46-0.95; P=0.023). By combining SRD5A1 (rs518673T) and SRD5A2 (rs 12470143 A), the protective effect was shown to be additive with the maximum protection conferred by 3 or 4 alleles (HR=0.33, 95% CI, 0.17-0.63; P=0.001). Conclusion. Germline polymorphisms in 5a-reductase genes are independent prognostic genetic biomarkers that predict PCa biochemical recurrence after radical prostatectomy and may represent useful molecular tools for a genotype-tailored clinical approach.
