Abstract

Introducing a new surgical technology may affect behaviors and attitudes of patients and surgeons about clinical practice. Robot-assisted laparoscopic radical prostatectomy (RALP) was approved in 2012 in Japan. We investigated whether the introduction of this system affected the treatment of organ-confined prostate cancer (PCa) and the use of radical prostatectomy (RP). We conducted a retrospective multicenter study on 718 patients with clinically determined organ-confined PCa treated at one of three Japanese academic institutions in 2011 (n = 338) or 2013 (n = 380). Two patient groups formed according to the treatment year were compared regarding the clinical characteristics of PCa, whether referred or screened at our hospital, comorbidities and surgical risk, and choice of primary treatment. Distribution of PCa risk was not changed by the introduction of RALP. Use of RP increased by 70% (from 127 to 221 cases, p < 0.0001), whereas the number of those undergoing radiotherapy or androgen deprivation therapy decreased irrespective of the disease risk of PCa. Increased use of RP (from 34 to 100 cases) for intermediate- or high-risk PCa patients with mild perioperative risk (American Society of Anesthesiologists score 2) accounted for 70% of the total RP increase, whereas the number of low- or very low-risk PCa patients with high comorbidity scores (Charlson Index ≥ 4) increased from 8 to 25 cases, accounting for 18%. Use of expectant management (active surveillance, watchful waiting) in very low-risk PCa patients was 15% in 2011 and 12% in 2013 (p = 0.791). Introduction of a robotic surgical system had little effect on the risk distribution of PCa. Use of RP increased, apparently due to increased indications in patients who are candidates for RP but have mild perioperative risk. Although small, there was an increase in the number of RPs performed on patients with severe comorbidities but with low-risk or very low-risk PCa.

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 12 November 2017.
All research outputs
#9,698,398
of 12,129,026 outputs
Outputs from International Journal of Clinical Oncology
#467
of 787 outputs
Outputs of similar age
#203,747
of 281,101 outputs
Outputs of similar age from International Journal of Clinical Oncology
#5
of 10 outputs
Altmetric has tracked 12,129,026 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 787 research outputs from this source. They receive a mean Attention Score of 3.5. This one is in the 19th percentile – i.e., 19% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 281,101 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 16th percentile – i.e., 16% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 10 others from the same source and published within six weeks on either side of this one. This one has scored higher than 5 of them.
