Purpose: Robotic-assisted radical prostatectomy (RARP) is known as a more oncological safety procedure compared to radical prostatectomy. Patient with positive margin after operation has a higher risk of biochemical failure. However, the treatment after positive margin was still controversial. The aims of this study was to find out the risk of biochemical failure over patients with positive margin after operation.
Materials and Methods: We evaluated total 462 patients who received RARP at LinKou Chang Gung Memorial Hospital during 2006-2014 with 61 patients with positive margin and didn’t received any treatment before biochemical failure. 1 patient was excluded due to lost following up. COX regression analysis and Kaplan-Meier Curve were used to compared between patient with biochemical failure ( n=19) and without biochemical failure (n=41).
Results: Overall 13.2% patients had positive margin with 31.7% turned out to be biochemical failure (BCF). The mean followed up months was 43.66 months ( 42.42 vs. 46.35(BCF), p=0.51). In multivariable analysis, Platelet and Lymphocyte ratio(PL ratio) ( 6.26 vs. 8.02(BCF), p=0.001) showed statistically significant. And, if we separated the patients to two group by pathology grading group <2 and >3 (p=0.001), it also showed statistically significant. Kaplan-Meier Curve was also used to analyze when PL ratio <=9 or >9 and it showed p value = 0.017.
Conclusions: If patients who received RARP with positive margin had PL ratio >9 by pre-operation lab data and pathology grading group >3, we strongly suggested early intervention should be applied over these patients.
