Objectives

To evaluate postoperative health resource utilisation and secondary care costs for radical prostatectomy and partial nephrectomy in National Health Service (NHS) hospitals in England, via a comparison of robot-assisted, conventional laparoscopic and open surgical approaches.

Patients and Methods

We retrospectively analysed the secondary care records of 23 735 patients who underwent robot-assisted (RARP, n = 8 016), laparoscopic (LRP, n = 6 776) or open radical prostatectomy (ORP, n = 8 943). We further analysed 2 173 patients who underwent robot-assisted (RAPN,n = 365), laparoscopic (LPN, n = 792) or open partial nephrectomy (OPN, n = 1 016). Postoperative inpatient admissions, hospital bed-days, excess bed-days and outpatient appointments at 360 and 1 080 days after surgery were reviewed.

Results

Patients in the RARP group required significantly fewer inpatient admissions, hospital bed-days and excess bed-days at 360 and 1 080 days than patients undergoing ORP. Patients undergoing ORP had a significantly higher number of outpatient appointments at 1 080 days. The corresponding total costs were significantly lower for patients in the RARP group at 360 days (£1679 vs £2031 for ORP; P < 0.001) and at 1 080 days (£3461 vs £4208 for ORP; P < 0.001). In partial nephrectomy, Patients in the RAPN group required significantly fewer inpatient admissions and hospital bed-days at 360 days compared with those in the OPN group; no significant differences were observed in outcomes at 1 080 days. The corresponding total costs were lower for patients in the RAPN group at 360 days (£779 vs £1242 for OPN,P = 0.843) and at 1 080 days (£2122 vs £2889 for ORP; P = 0.570). For both procedure types, resource utilisation and costs for laparoscopic surgeries lay at the approximate midpoint of those for robot-assisted and open surgeries.

Conclusion

Our analysis provides compelling evidence to suggest that RARP leads to reduced long-term health resource utilisation and downstream cost savings compared with traditional open and laparoscopic approaches. Furthermore, despite the limitations that arise from the inclusion of a small sample, these results also suggest that robot-assisted surgery may represent a cost-saving alternative to existing surgical options in partial nephrectomy. Further exploration of clinical cost drivers, as well as an extension of the analysis into subsequent years, could lend support to the wider commissioning of robot-assisted surgery within the NHS.

Objectives

To investigate whether the International Society of Urological Pathology (ISUP) 2005 revision of the Gleason grading system has influenced the risk of biochemical recurrence (BCR) after radical prostatectomy (RP), as the new guideline implies that some prostate cancers previously graded as Gleason score 6 (3 + 3) are now considered as 7 (3 + 4).

Patients and methods

A matched-pair analysis was conducted. In all, 215 patients with Gleason score 6 or 7 (3 + 4) prostate cancer on biopsy who underwent RP before 31 December 2005 (pre-ISUP group), were matched 1:1 by biopsy Gleason score, clinical tumour category, PSA level, and margin status to patients undergoing RP between 1 January 2008 and 31 December 2011 (post-ISUP group). Patients were followed until BCR defined as a PSA level of ≥0.2 ng/mL. Risk of BCR was analysed in a competing-risk model.

JunAOTMResults

Results

The median follow-up was 9.5 years in the pre-ISUP group and 4.8 years in the post-ISUP group. The 5-year cumulative incidences of BCR were 34.0% and 13.9% in the pre-ISUP and post-ISUP groups, respectively (P < 0.001). The difference in cumulative incidence applied to both patients with Gleason score 6 (P < 0.001) and 7 (3 + 4) (P = 0.004). There was no difference in the 5-year cumulative incidence of BCR between patients with pre-ISUP Gleason score 6 and post-ISUP Gleason score 7 (3 + 4) (P = 0.34). In a multiple Cox-proportional hazard regression model, ISUP 2005 grading was a strong prognostic factor for BCR within 5 years of RP (hazard ratio 0.34; 95% confidence interval 0.22–0.54; P < 0.001).

Conclusion

The revision of the Gleason grading system has reduced the risk of BCR after RP in patients with biopsy Gleason score 6 and 7 (3 + 4). This may have consequences when comparing outcomes across studies and historical periods and may affect future treatment recommendations.

Editorial: Current Gleason score 3 + 4 = 7: has it lost its significance compared with its historical counterpart?

/by

Berg et al. [1] report that patients classified as Gleason score 7 (3 + 4) according to the revised grading system published in 2005 are to some extent similar to patients with pre-2005 Gleason score 6, at least in terms of risk of biochemical recurrence. The logical but not necessarily correct conclusion is that current patients with Gleason score 7 on biopsy are appropriate candidates for active surveillance.

What must be kept in mind is that, using the post-2005 revised grading system, approximately 25% of men with Gleason score 3 + 4 = 7 on biopsy have either 3 + 4 = 7 with tertiary pattern 5 or >4 + 3 = 7 in the corresponding radical prostatectomy [1]. With the exception of men with a limited life expectancy, these men need definitive therapy for their potentially life-threatening cancer. Numerous studies have shown that extended biopsies, whether they are >10- or 12-core, are associated with less upgrading than sextant biopsies [2]. In the report by Berg et al. [1], the median number of cores sampled before 2005 was 6 with an interquartile range (IQR) of 6–6 compared with a median (IQR) of 10 (10–12) cores after 2005. Consequently, in their cohorts, the pre-2005 group of men with Gleason score 3 + 3 = 6 were more likely to have unsampled higher grade cancer and a correspondingly worse prognosis more closely approximating post-2005 better-sampled Gleason score 3 + 4 = 7 cancers.

Berg et al. [1] further claim that the prognostic and clinical value of Gleason score 7 has been weakened since the 2005 modifications. In fact, the revised grading system more accurately reflects prostate cancer biology than the pre-2005 Gleason system. The major consequence of the modification, as Berg et al. [3] illustrate, has been the better prognosis associated with post-2005 Gleason score 6 cancer because patterns associated with more aggressive behaviour have been shifted to Gleason score 7. Historically, a diagnosis of Gleason score 6 cancer, even at radical prostatectomy, was not as predictive of ‘good’ behaviour, and had a higher rate of progression with some men even dying from prostate cancer [4]. Currently, Gleason score 6 cancer at radical prostatectomy has a 96% cure rate at 5 years, even including cases with extraprostatic extension and positive margins [3]. Several studies have shown that post-2005 pure Gleason score 6 cancers at radical prostatectomy are incapable of metastasizing to lymph nodes [4]. Berg et al. are correct, however, that men with a post-2005 grade of Gleason Score 3 + 4 = 7 have a better prognosis than those graded prior to 2005. As a consequence, it has been recommended that pathologists should record the percent pattern 4 in cases with Gleason score 7 on biopsy for men being considered for active surveillance [5]. For the appropriate patient, depending on age, comorbidity, extent of cancer, MRI findings, patient desire, etc., could be a candidate for active surveillance with Gleason score 3 + 4 = 7 if the pattern 4 is limited. Currently, this information is not transparent in most pathology reports.

A new grading system, first proposed in BJUI by this author, and verified in a large multi-institutional study, resulted in a simplified five-grade group system that more accurately reflects the biology of prostate cancer than the pre-2005 grading system [3, 6]. Men with Gleason score 6 cancers need to be reassured that their cancer is the lowest grade that is currently assigned, despite Gleason scores ranging from 2 to 10. In addition, I have talked to some patients with Gleason score 3 + 4 = 7 who think that they are going to die in the near future because their score of 7 was closer to highest grade of 10 than the lowest grade of 2. With the new grading system, patients can be reassured that they have a Grade group 1 (3 + 3 = 6) out of 5, which is the lowest grade, or a Grade group 2 (Gleason score 3 + 4 = 7) out of 5, which is still a relatively low grade.

Objectives

To examine the detection rates of 68Ga-PSMA-positron emission tomography (PET)/computed tomography (CT) in patients with biochemical recurrence (BCR) after radical prostatectomy (RP), and also the impact on their management.

Materials and Methods

A total of 300 consecutive patients with prostate cancer (PCa) who underwent 68Ga-PSMA-PET/CT between February and July 2015 were prospectively included in the Prostate Cancer Imaging (ProCan-I) database. For the present analysis, we included patients with BCR (prostate-specific antigen [PSA] level ≥0.05 and <1.0 ng/mL) after RP, who were being considered for salvage radiation therapy (RT) according to the Faculty of Radiation Oncology Genito-Urinary Group (FROGG) guidelines. Two readers assessed each 68Ga-PSMA-PET/CT, and all positive lesions were assigned to an anatomical location. For each patient, the clinical and pathological features were recorded, their association with pathological 68Ga-PSMA uptake was investigated, and detection rates were determined according to PSA level.

AOTWMAY

Results

A total of 70 patients were included, and 53 positive 68Ga-PSMA lesions were detected in 38 (54%) patients. Among patients with PSA levels 0.05–0.09 ng/mL, 8% were definitely positive; the corresponding percentages for the other PSA ranges were as follows: PSA 0.1–0.19 ng/mL, 23%; PSA 0.2–0.29 ng/mL, 58%; PSA 0.3–0.49 ng/mL, 36%; and PSA 0.5–0.99 ng/mL, 57%. Eighteen of 70 patients (27%) had pathological 68Ga-PSMA uptake in the prostatic fossa, 11 (14.3%) in the pelvic nodes, and five (4.3%) in both the fossa and pelvic lymph nodes. Finally, there was uptake outside the pelvis with or without a lesion in the fossa or pelvic lymph nodes in four cases (8.6%). As a result of the 68Ga-PSMA findings there was a major management change in 20 (28.6%) patients.

Conclusions

68Ga-PSMA appears to be useful for re-staging of PCa in patients with rising PSA levels who are being considered for salvage RT even at PSA levels <0.5 ng/mL. These results underline the need for further prospective trials to evaluate the changes in RT volume or management attributable to 68Ga-PSMA findings.

Editorial: PSMA-targeted imaging of PCa – the best is yet to come

/by

In recent years there has been increasing interest in imaging recurrent or metastatic prostate cancer with positron-emission tomography (PET) radiotracers targeting prostate-specific membrane antigen (PSMA [1]). The majority of this work has been performed using urea-based small molecules labelled with gallium-68 (68Ga). Within this class of radiotracers, 68Ga-PSMA-11 (also known as 68Ga-PSMA-HBED-CC) has been the most widely studied. In this month’s edition of BJUI, van Leeuwen et al. [2] report on the clinical utility of 68Ga-PSMA-11 PET/CT in men with rising PSA levels after radical prostatectomy being considered for salvage radiation therapy. In their study, 70 patients with negative conventional imaging findings and a median PSA of 0.2 ng/mL (all <1 ng/mL) were imaged with 68Ga-PSMA-11 PET/CT prior to initiating treatment. On PSMA-targeted PET/CT, 53 lesions were detected in 38 (54%) patients. Perhaps most significant among their findings was that 28.6% of men had radiotracer uptake outside of the prostatic fossa leading to a major change in clinical management. In total, these data demonstrate the great potential of PSMA-targeted imaging, particularly in men with biochemically recurrent prostate cancer.

While a great deal of encouraging data with 68Ga-PSMA-11 has appeared in the medical literature, it is worth noting that several other small molecules that offer potential advantages over this agent have seen early clinical development. For example, PSMA-617 makes use of the DOTA chelation moiety in place of HBED-CC, allowing for a scaffold that can accommodate both diagnostic 68Ga and therapeutic lutetium-177 (177Lu) [3]. Additionally, our group has focused on fluorine-18 (18F)-labelled urea-based small molecules targeting PSMA, most recently 18F-DCFPyL [4]. 18F-labelled small molecules offer several potential advantages over those labelled with 68Ga. These include more favourable dosimetry allowing for higher injected radiotracer doses and lower-energy emitted positrons that have shorter path lengths to annihilation and therefore higher intrinsic spatial resolution [5]. Notably, a recent direct comparison of 68Ga-PSMA-11 and 18F-DCFPyL performed by Dietlein et al. [6] seems to confirm these advantages, having observed a higher rate of lesion detection as well as superior mean tumour-to-background ratios with the radiofluorinated compound. An additional advantage of 18F-labelled compounds is related to their longer half-life for radionuclide decay (109 vs 68 min for 68Ga). Given this difference, agents incorporating 68Ga typically require an on-site generator for radiotracer production, whereas 18F-based radiotracers can be produced en masse at a central site with a cyclotron and then delivered to remote locations via pre-existing distribution infrastructure (e.g. PETNET in the USA). Table 1 summarizes several relevant differences in the physical properties of 68Ga and 18F.

Table 1. Comparison of gallium-68 and fluorine-18
Radionuclide 68Ga 18F
Half-life, min 68 109
Method of production Generator Cyclotron
Average positron energy, keV 836.0 249.3
Average path length in soft tissue, mm 8.1 2.4
Positron yield per 100 disintegrations 89.14 96.86

 

In summary, these are exceptionally exciting times for the study of PSMA-targeted imaging of prostate cancer. With continued radiotracer development and accompanying well-designed clinical trials, there is no doubt we can drastically improve the care of men with prostate cancer.

OBJECTIVE

To estimate time trends in the recourse to radical prostatectomy (RP) and associated short-term outcomes after RP in Italy, as population-based data on RP adoption and outcomes are available mainly from Northern America and Northern Europe.

PATIENTS AND METHODS

All RPs for prostate cancer performed between 2001 and 2010 were extracted from the Italian national archive of hospital discharge records. Age-specific and age-standardised RP rates were computed. The effect of procedural volume on in-hospital mortality, complications, and length of stay (LOS) was estimated by multilevel regression models.

RESULTS

In all, 144 432 RPs were analysed. Country-wide RP rates increased between 2001 and 2004, and thereafter remained stable, with large differences between geographical areas. The mean hospital volume increased in the first study years, without centralisation but due to increasing RP numbers at the population level. The median LOS declined from 10 to 8 days over the study period (mean from 11.7 to 9.2 days). In-hospital mortality declined from 0.16% in 2001 to 0.07% in 2010. In-hospital mortality, LOS, and the prevalence of complications increased with age, and decreased with year of surgery. Compared with very low-volume hospitals, procedures performed in high-volume hospitals were associated with decreased in-hospital mortality, in-hospital complications, and LOS.

CONCLUSIONS

The study adds evidence on rapidly changing trends in RP rates in Italy, on improving in-hospital outcomes, and on their association with procedural volume.

Editorial: How Can We Improve Surgical Outcomes?

/by

How to improve surgical outcomes for all is a long-standing health policy/services research question. There are generally two perspectives to the debate. One reasonable approach would be to regionalise, or centralise, the performance of a procedure, in this case radical prostatectomy (RP), to ‘specialised’ surgeons or institutions. Data from the USA show that regionalisation of prostate cancer care initially occurred in the late 1990s and even further more recently after the introduction of robotic surgery. The improvement of surgical outcomes after RP in the USA has been partially attributed to such phenomena [1]. Conversely, it may be impossible to centralise a common procedure, such as RP, to a small number of hospitals, concerns that were raised in an review on improving surgical care by Hollenbeck et al. [2]. Alternatively, large state or national quality improvement initiatives, with incremental advances in process-of-care adoption/compliance, may improve the care of prostate cancer for all. This collaborative and inclusive approach is, for example, employed by the Michigan Urological Surgery Improvement Collaborative (MUSIC). However, one has to factor in that this type of approach demands funding, collaboration and patience. Regardless, there is little doubt that both approaches, enforced by health policy or not, are needed in large and diverse countries such as the USA.

In this issue of BJU International, Novara et al. [3] examine the trends in RP utilisation within Italy. The authors have to be commended for their efforts to raise awareness of the need for concerted cancer registries and centralised treatments. They corroborated previous studies on the relationship between hospital volume and perioperative outcomes, such as in-hospital mortality, complications and length of stay [4]. They also found an improvement in perioperative outcomes over time. Although their study design may only allow us to speculate on the reasons for these improvements, they are likely to be the result of many factors, such as improved surgical technique, improved perioperative medical/anaesthetic care and regionalisation of care. For surgical technique, the only significant advance over the past decade was the introduction of robot-assisted RP. Given the late adoption of robotic surgery in Italy and the controversy about its benefits, this is unlikely to be the major driver behind the recorded trends. On perioperative medical/anaesthetic care, the past decade has seen major advances and standardisation of thromboembolic prevention, perioperative care of patients with pre-existing heart conditions and significant comorbidities. Finally, centralisation of care may have played an important role in the decreasing rates of adverse outcomes after RP. Although the authors specify that there was no policy-driven regionalisation of RP care in Italy (relative to the UK, for example), the increase in average hospital volume should translate into better outcomes, as discussed above [4]. Further regionalisation should be expected in Italy with the adoption of robotic surgery, as only a few centres have the means and logistics to support a da Vinci system [5].

OBJECTIVE

To estimate time trends in the recourse to radical prostatectomy (RP) and associated short-term outcomes after RP in Italy, as population-based data on RP adoption and outcomes are available mainly from Northern America and Northern Europe.

PATIENTS AND METHODS

All RPs for prostate cancer performed between 2001 and 2010 were extracted from the Italian national archive of hospital discharge records. Age-specific and age-standardised RP rates were computed. The effect of procedural volume on in-hospital mortality, complications, and length of stay (LOS) was estimated by multilevel regression models.

RESULTS

In all, 144 432 RPs were analysed. Country-wide RP rates increased between 2001 and 2004, and thereafter remained stable, with large differences between geographical areas. The mean hospital volume increased in the first study years, without centralisation but due to increasing RP numbers at the population level. The median LOS declined from 10 to 8 days over the study period (mean from 11.7 to 9.2 days). In-hospital mortality declined from 0.16% in 2001 to 0.07% in 2010. In-hospital mortality, LOS, and the prevalence of complications increased with age, and decreased with year of surgery. Compared with very low-volume hospitals, procedures performed in high-volume hospitals were associated with decreased in-hospital mortality, in-hospital complications, and LOS.

CONCLUSIONS

The study adds evidence on rapidly changing trends in RP rates in Italy, on improving in-hospital outcomes, and on their association with procedural volume.

OBJECTIVE

To identify which high-risk patients with prostate cancer may harbour favourable pathological outcomes at radical prostatectomy (RP).

PATIENTS AND METHODS

We evaluated 810 patients with high-risk prostate cancer, defined as having one or more of the following: PSA level of >20 ng/mL, Gleason score ≥8, clinical stage ≥T2c. Patients underwent robot-assisted RP (RARP) with pelvic lymph node dissection, between 2003 and 2012, in one centre. Only 1.6% (13/810) of patients received any adjuvant treatment. Favourable pathological outcome was defined as specimen-confined disease (SCD; pT2–T3a, node negative, and negative surgical margins) at RARP-specimen. Logistic regression models were used to test the relationship among all available predicators and harbouring SCD. A logistic regression coefficient-based nomogram was constructed and internally validated using 200 bootstrap resamples. Kaplan–Meier method estimated biochemical recurrence (BCR)-free and cancer-specific mortality (CSM)-free survival rates, after stratification according to pathological disease status.

RESULTS

Overall, 55.2% patients harboured SCD at RARP. At multivariable analysis, PSA level, clinical stage, primary/secondary Gleason scores, and maximum percentage tumour quartiles were all independent predictors of SCD (all P < 0.04). A nomogram based on these variables showed 76% discrimination accuracy in predicting SCD, and very favourable calibration characteristics. Patients with SCD had significantly higher 8-year BCR- (72.7% vs 31.7%, P < 0.001) and CSM-free survival rates (100% vs 86.9%, P < 0.001) than patients with non-SCD.

CONCLUSIONS

We developed a novel nomogram predicting SCD at RARP. Patients with SCD achieved favourable long-term BCR- and CSM-free survival rates after RARP. The nomogram may be used to support clinical decision-making, and aid in selection of patients with high-risk prostate cancer most likely to benefit from RARP.
