Objectives
Our aim was to evaluate the predictors of biochemical recurrence after Retzius‐sparing robot‐assisted radical prostatectomy.
Methods
The study cohort consisted of 359 consecutive non‐metastatic prostate cancer patients who underwent Retzius‐sparing robot‐assisted radical prostatectomy between November 2012 and January 2016. According to the National Comprehensive Cancer Network prostate cancer risk classification, 164 patients (45.7%) had high‐ or very high‐risk prostate cancer. No patient received adjuvant therapy until documented biochemical recurrence. Biochemical recurrence‐free survival was estimated using the Kaplan–Meier method. Univariable and multivariable Cox proportional hazards regression models were used to determine variables predictive of biochemical recurrence.
Results
The median follow‐up period was 26 months (interquartile range 19–38 months). The overall biochemical recurrence rate was 14.8%, and the median time to biochemical recurrence was 11 months (interquartile range 6–22 months). The 3‐year biochemical recurrence‐free survival probability was 71.2%, 72.1%, 88.7%, 82.3% and 95.7% in very high‐, high‐, intermediate‐, low‐ and very low‐risk prostate cancer, respectively (log–rank, P < 0.001). On multivariable analysis, preoperative prostate‐specific antigen (hazard ratio 1.03, 95% confidence interval 1.02–1.04; P < 0.0001), percentage of maximum core involvement on biopsy (hazard ratio 1.02, 95% confidence interval 1.01–1.03; P = 0.029) and clinical stage ≥T3a (hazard ratio 2.12, 95% confidence interval 1.02–4.39; P = 0.043) were predictors of biochemical recurrence, whereas pathological Gleason score ≥8 (hazard ratio 5.63, 95% confidence interval 1.62–19.61; P = 0.007) and pathological tumor volume (hazard ratio 1.08, 95% confidence interval 1.04–1.20; P < 0.001) were the main pathological predictors of biochemical recurrence.
Conclusions
Retzius‐sparing robot‐assisted radical prostatectomy confers effective biochemical recurrence control at the mid‐term follow‐up period. Preoperative prostate‐specific antigen, advanced clinical stage and higher Gleason score were important predictors of biochemical recurrence after Retzius‐sparing robot‐assisted radical prostatectomy. Long‐term oncological safety still needs to be established.
Successful implementation of virtual healthcare depends immensely on patients’ perceptions and satisfaction. This cross-sectional study assessed patients’ perceptions of, and factors associated with, poor and average satisfaction with the outpatient telemedicine clinics in the Kingdom of Saudi Arabia (KSA). This questionnaire-based survey was conducted among 720 patients who attended outpatient telemedicine clinics from different regions of the KSA. Of the sample studied, 54.7% of the participants had high satisfaction and the most common disadvantage perceived by patients was technical issues (53.1%), followed by fewer personal interactions (30.4%). Around 75% of the participants desired to use telemedicine services even after the COVID-19 pandemic. Logistic regression analysis revealed that age group more than 40 years (OR = 1.59; 95% CI = 1.04–2.44, p = 0.031), education less than university level (OR = 1.68; 95% CI = 1.07–2.15, p = 0.025), and first-time participants (OR = 3.28; 95% CI = 2.32–4.65, p < 0.001) were significantly associated with poor and average satisfaction ratings. The concerned authorities must make targeted action plans to circumvent the disadvantages perceived by patients accessing telemedicine. Furthermore, a multicenter, exploratory study that compares the virtual clinic with other telemedicine services in the KSA is warranted.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
