99% Survival at 10 Years for Robot-Assisted Radical Prostatectomy

In one of teh few studies to assess long term outcomes following robotically assisted prostatectomy surgery, researchers from Henry Ford Hospital have issued a press release which they say points to solid results out to 10 years.

Background

The researchers followed 483 consecutive men who had cancer that had not spread outside the prostate and received Robot Assisted Radical Prostatectomy (RARP) as their first treatment. All cases were from 2001 to 2003, the earliest years of Henry Ford’s robot-assisted prostate surgery program.

Using several standard measures of cancer-treatment success the researchers found that 98.8 percent of the patients survived cancer for 10 years after their surgery.

Further analysis showed that the severity of the cancer after RARP was the best predictor of a recurrence, and the level of prostate-specific antigen, or PSA, in the bloodstream can be combined with severity to determine future treatment.

The study also suggested that traditional methods of measuring the severity and possible spread of the cancer together with molecular techniques might, with further research, help to create personalized, cost-effective treatment regimens for prostate cancer patients who undergo the surgical procedure.

The findings apply to men whose cancer has not spread beyond the prostate, and the results are comparable to the well-established and more invasive open surgery to remove the entire diseased prostate and some surrounding tissue.

The research study is published this month online in European Urology, the official journal of the European Association of Urology.

Investigator comments

“Until our analysis, there was little available information on the long-term oncologic outcomes for patients who undergo robot-assisted radical prostatectomy, or RARP,” says Mireya Diaz, Ph.D., Director of Biostatistics at the Henry Ford’s Vattikuti Urology Institute (VUI) and lead author of the study.

“As one of the very first hospitals to establish a structured RARP program a little over a decade ago, we were able to determine the long-term effectiveness of the technique thanks to the continued feedback of our patients and the follow-up efforts of the VUI team,” Dr. Diaz adds.

“Disease severity and postoperative PSA measurements can guide physicians in identifying the varying levels of cancer recurrence risk,” Dr. Diaz explains. “This includes those patients who can best benefit from secondary treatment as well as long-term monitoring.”
