Port-Site Metastases After Robotic Radical Cystectomy: A Systematic Review and Management Options - Beyond the Abstract
A recent study in the journal Clinical Genitourinary Cancer attempted to define the incidence of port-site metastases in patients undergoing robotic radical cystectomy. The investigators performed a systematic review of publication databases including MEDLINE and Embase to identify reports of port-site metastases after robotic radical cystectomy. They found 4 cases and reported an additional case from their own practice. As expected, all 5 patients had muscle-invasive bladder cancer cystectomy. Three patients had lymph node-positive disease. The authors concluded that the incidence of port-site metastases robotic radical cystectomy was < 0.5%. Given the small number of cases reported in the literature, this estimate is expected to change as more evidence is published.
The authors note that the incidence of port-site metastases associated with robotic radical cystectomy for bladder cancer was slightly higher than the reported incidence associated with laparoscopic surgery for combined genitourinary cancers (0.09%), prostate cancer (0.1%), and kidney cancers (0.1%). In contrast, this rate was lower when compared to robotic surgeries for gynecologic cancers (1.1% to 1.9%.).
The investigators also point out that the incidence of incision-site metastases with open cystectomy is also not well described. Systematic reporting of port-site metastases is critical to define the optimal strategies for prevention and treatment of this dreaded complication
