Effects of Simultaneous Transurethral Resection of Prostate and Solitary Bladder Tumors Smaller Than 3 cm on Oncologic Results

Concomitant Endoscopic Surgery for Bladder Tumors and Prostatic Obstruction: Are We Safely Hitting Two Birds with One Stone? A Systematic Review and Meta-Analysis

BACKGROUND

Lower urinary tract symptoms (LUTS) caused by benign prostatic obstruction (BPO) and bladder tumors may co-exist, especially among elderly patients. Transurethral resection of bladder tumors (TURBT) and endoscopic surgery for benign prostatic obstruction in the same setting are avoided by many surgeons due to concerns for tumor cell seeding and recurrences in the prostatic urethra.

AIM

The aim of this study was assess the effect of concomitant TURBT and endoscopic BPO surgery on oncological safety and patient quality of life via systematic review and meta-analysis.

METHODS

We searched the PubMed, Cochrane Library, EMBASE, Scopus, and Clinicaltrials.gov databases and sources of grey literature published before June 2021 for relevant studies. We performed a random-effects meta-analysis of odds ratios (ORs) or weighted mean differences (WMD) to compare concomitant TURBT and BPO surgery versus TURBT alone in terms of recurrence and progression rates. Accordingly, we undertook multiple subgroups and sensitivity analyses (PROSPERO: CRD42020173363).

RESULTS

Three randomized and twelve retrospective observational studies with 2421 participants were included. Across studies with good methodological quality, no statistically significant differences were demonstrated regarding overall bladder tumors recurrence rates between concomitant endoscopic BPO surgery and TURBT versus TURBT alone (OR: 0.81, 95% CI: 0.60-1.09, I² = 42%). Similarly, no significant differences were observed in recurrences located at the bladder neck and/or prostatic urethra (OR: 1.06, 95% CI: 0.76-1.47, I² = 0%), time to first recurrence (WMD: -0.2 months, 95% Cl: -2.2-1.8, I² = 48%), and progression rate (OR: 1.05, 95% CI: 0.67-1.64, I² = 0%). Subgroup analyses based on tumor grade, number of tumors, and utilization of single-instillation chemotherapy post-TURBT did not detect any significant differences in overall bladder tumor recurrence. The level of evidence was estimated as low for all outcomes. Concomitant surgery improved lower urinary tract symptoms.

CONCLUSION

Concomitant endoscopic BPO surgery and TURBT are oncologically safe and improve LUTS-related quality of life.

Assessment of the clinical efficacy of simultaneous transurethral resection of both bladder cancer and the prostate: a systematic review and meta-analysis

OBJECTIVE

In this study, we aimed to examine the clinical efficacy of simultaneous transurethral resection of bladder cancer and the prostate (TURBT + TURP) in non-muscle invasive bladder cancer (NMIBC) and benign prostatic hyperplasia (BPH) patients.

METHOD

We conducted systematic research in PubMed, EMBASE, and Cochrane Library databases to identify retrospective studies and prospective randomized controlled trials (RCTs) comparing patient outcomes between TURBT + TURP and TURBT-only patients. The meta-analysis was conducted using Review Manager 5.3.

RESULTS

We identified eight relevant studies involving a total of 1032 patients. We found that patients that underwent TURBT + TURP exhibited significantly lower recurrence rates [odds ratio (OR), 0.70; 95% confidence interval (CI), 0.53-0.93; p = .01] and increased maximal urinary flow rate (Qmax) (WMD, 5.92; 95% CI, 4.67-7.16; p < .001) compared with patients that underwent TURBT-only. However, rates of recurrence at the prostatic urethra/bladder neck and bladder tumor progression, as well as the time to recurrence did not differ significantly between these two groups.

CONCLUSIONS

Simultaneous TURBT + TURP can be safely performed in patients with NMIBC and BPH and improves patient quality of life, without any risk of increasing tumor recurrence or metastasis rates. Comprehensive RCTs are needed to confirm the results of this study.

The recurrence and progression risk after simultaneous endoscopic surgery of urothelial bladder tumour and benign prostatic hyperplasia: a systematic review and meta-analysis

Objectives

To evaluate recurrence and progression risk after simultaneous endoscopic surgery of bladder cancer and benign prostatic hyperplasia (BPH), as simultaneous surgery is not an unusual scenario and theoretically simultaneous transurethral resection of bladder tumour (TURBT) and transurethral resection of the prostate (TURP) can lead to an increased risk of recurrence in the bladder neck and prostatic urethra (BN/PU).

Methods

We conducted a systematic review and meta‐analysis to assess the risk of recurrence (i.e. whole bladder and/or BN/PU) and tumour progression as outcomes after a simultaneous endoscopic surgery of bladder tumour and BPH, as compared to TURBT alone. We queried PubMed and Web of Science database on 1 January 2020. We used random‐ and/or fixed‐effects meta‐analytic models in the presence or absence of heterogeneity according to the I² statistic, respectively.

Results

Nine retrospective and three clinical trial studies were selected after considering inclusion and exclusion criteria. We conducted the meta‐analysis on retrospective and randomised controlled trials (RCTs) separately. Eight retrospective and three RCT studies were included to assess the BN/PU recurrence risk and the summarised risk ratio (RR) was 1.02 (95% confidence interval [CI] 0.74–1.41) and 0.93 (95% CI 0.47–1.84), respectively. Five retrospective and two RCT studies were included to assess the progression risk and the summarised RR was 0.91 (95% CI 0.56–1.48) and 1.16 (95% CI 0.30–4.51), respectively. Eight retrospective and three RCT studies were included to assess the whole bladder recurrence risk and the summarised RR was 0.87 (95% CI 0.78–0.97) and 0.89 (95% CI 0.65–1.21), respectively.

Conclusion

We did not observe any increased risk of total bladder recurrence, BN/PU recurrence, or progression after a simultaneous endoscopic surgery of bladder tumour and BPH, as compared to TURBT alone.

Oncological safety and quality of life in men undergoing simultaneous transurethral resection of bladder tumor and prostate: results from a randomized controlled trial

PURPOSE

To assess oncological safety and quality of life (QL) of men undergoing simultaneous transurethral resection of bladder tumor (TURBT) and transurethral resection of the prostate (TURP) for symptomatic benign prostatic hyperplasia (BPH).

METHODS

Ninety-five men with a new diagnosis of bladder cancer (BC) and symptomatic BPH were randomized to receive TURBT + tamsulosin (Group 1) or TURBT + TURP (Group 2). Inclusion criteria were age ≤ 75 years, first diagnosis of BC up to 4 cm, and prostate volume ≤ 80 ml. All patients were evaluated preoperatively with digital rectal examination, PSA, maximal urine flow rate (Q_max), and International Prostate Symptom Score (IPSS). IPSS and Q_max were repeated at 1-year follow-up. QL was evaluated at 1 year using a modified version of the self-report bladder cancer subscale of the Functional Assessment of Cancer Therapy.

RESULTS

Eighty-five men completed the study (43 in Group 1 and 42 in Group 2). Adjuvant instillation therapy was given to 26 patients in Group 1 and to 27 in Group 2. Average time to the first recurrence was 16.64 months in Group 1 and 17.7 in Group 2. Total recurrences were 27 in Group 1 and 22 in Group 2. Bladder neck/prostatic urethra recurrences were 9 in Group 1 vs. 8 in Group 2. QL, IPSS, and Q_max 12 months after surgery were better in Group 2.

CONCLUSION

Concomitant TURBT and TURP appear to be oncologically safe procedures in terms of total and prostatic urethra recurrence, and improve QL in men with BC who require surgery for symptomatic BPH.

The efficacy and safety of simultaneous transurethral GreenLight photoselective vaporization of bladder tumor and prostate in patients with bladder tumor and lower urinary tract symptoms

PURPOSE

We compared the safety and efficacy of simultaneous transurethral GreenLight photoselective vaporization of bladder tumor and prostate (PVBT/PVP) in patients with bladder tumor and bladder outlet obstruction caused by benign prostate hyperplasia (BPH).

METHODS

Sixty-two patients with bladder tumor were enrolled in our prospective and randomized trial. A total of 37 men underwent simultaneous transurethral PVBT/PVP, and 25 patients underwent PVBT alone. The clinicopathological parameters and the recurrence of bladder tumor on the bladder neck/prostatic fossa were evaluated in all patients.

RESULTS

Clinicopathological parameters of both groups were similar. The rates of recurrence, progression and tumor recurrence of bladder neck/prostatic fossa were 16.0, 4.0 and 4.0 % in the simultaneous resection group, and 18.9, 5.4 and 8.1 % in the group PVBT, respectively. No statistically significant differences were found between the two groups (P > 0.05).

CONCLUSIONS

Simultaneous PVBT/PVP may help decrease the overall recurrence rate and tumor recurrence in bladder neck/prostatic fossa. PVBT/PVP can be performed effectively and safely in patients with bladder tumor and BPH.

Simultaneous transurethral resection of bladder cancer and prostate may reduce recurrence rates: A systematic review and meta-analysis

The aim of this study was to evaluate the recurrence rate of simultaneous transurethral resection of bladder cancer and prostate (TURBT+TURP) in the treatment of non-muscle invasive bladder cancer (NMIBC) with benign prostatic hyperplasia (BPH). We searched PubMed, the Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE and the ISI Web of Knowledge databases from their establishment until March 2012, to collect all the original studies on TURBT+TURP vs. TURBT alone in the treatment of NMIBC with BPH. After screening the literature, methodological quality assessment and data extraction was conducted independently by two reviewers and meta-analysis was performed using the RevMan 5.1 software. The quality of data was assessed using the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) approach. Eight studies, including seven non-randomized concurrent controlled trials (NRCCTs) and one randomized controlled trial (RCT), involving a total of 1,372 patients met the criteria. Meta-analyses of NRCCTs showed that in the TURBT+TURP group, overall recurrence rates were lower [odds ratio (OR), 0.76; 95% confidence interval (CI), 0.60–0.96; P=0.02] and the difference was statistically significant. The postoperative recurrence rate in the prostatic fossa/bladder neck (OR, 0.96; 95% CI, 0.64–1.45; P=0.86) and bladder tumor progression rates (OR, 0.96; 95% CI, 0.49–1.87; P=0.91) were similar between the TURBT+TURP and TURBT groups, but the difference was not significant. According to the GRADE approach, the level of evidence was moderate or low. Only one RCT demonstrated that overall postoperative tumor recurrence rates, recurrence rates at prostate fossa/bladder neck and bladder tumor progression rates between simultaneous groups and control groups were almost equal. There was no significant difference (P>0.05), and the level of evidence was moderate. For patients with NMIBC and BPH, simultaneous resection did not increase the overall recurrence rate of bladder tumors, it also did not cause metastasis and tumor progression, but it may reduce the recurrence rate. However, due to the low quality of investigations included in the present study, careful selection was necessary, and more large-scale and high-quality randomized controlled trials are also required for further confirmation.

Is it oncologically safe performing simultaneous transurethral resection of the bladder and prostate? A meta-analysis on 1,234 patients

PURPOSE

It is not unusual to encounter the clinical scenario of a male patient undergoing endoscopic treatment for bladder cancer (TURBT) who also needs transurethral resection of prostate (TURP). The aims of this meta-analysis were to understand whether it is oncologically safe or advantageous to combine the two procedures in terms of subsequent overall recurrences with particular interest to that in the prostatic fossa and to understand whether some characteristics of the bladder tumors can influence the recurrence rate.

METHODS

A bibliographic search covering the period from January 1950 to December 2011 was conducted in PubMed, MEDLINE and EMBASE. Meta-analysis approach was applied comparing prostatic fossa recurrences and total recurrences in simultaneous TURBT and TURP and control. Also, prostatic fossa recurrences and tumors' grading and multifocality in patients treated with simultaneous TURBT and TURP were analyzed. To investigate to what extent observational time influenced relapses/recurrence, a random effect meta-regression logistic model-based approach was applied. All statistical evaluations were performed using SAS version 9.2 and by RevMan 5.0. An α level of 0.05 was considered as statistically significant.

RESULTS

Overall, there were 1,234 participants in the eight studies considered. The study group consists of 634 patients and the control group 600. Mean age was 67.88 and 61.64 years, respectively, in the study and control groups. In the study group, on a total of 634 patients, 65 recurrences in the prostatic fossa appear. In the control group, on a total of 600 patients, 58 recurrences in the prostatic fossa occurred. Data do not show a statistically significant difference in recurrence in the prostatic fossa between patients treated simultaneously with TURB and TURP and the control group. Meta-analysis does not show a statistically significant difference in recurrence in the prostatic fossa with the increased grading of the neoplasms. But there is a statistically significant increased recurrence in patients with multifocal tumors. There is a statistically significant reduction in recurrence between patients treated simultaneously with TURB and TURP and the control group, but there is no reduction in the recurrence rate in the time.

CONCLUSIONS

This meta-analysis emphasized that the two operations could be performed during the same session without any negative oncologic results. The resolution during the same session of bladder outlet obstruction will improve the patients' quality of life and performing the procedures in the same session sparing the patients from a further anesthesiological maneuvers and the need for a further hospitalization for the surgical resolution of the prostatic obstruction.

Does simultaneous transurethral resection of bladder tumor and prostate affect the recurrence of bladder tumor? A meta-analysis

PURPOSE

To evaluate the efficacy and safety of simultaneous resection in the treatment of nonmuscle invasive bladder cancer (NMIBC) with benign prostatic hyperplasia (BPH).

PATIENTS AND METHODS

Combined published data from comparative studies on simultaneous transurethral resection of bladder tumor/transurethral resection of the prostate (TURBT/TURP) vs TURBT alone in NMIBC were analyzed, considering possible confounding factors. Odds ratios (ORs) and 95% confidence intervals (CIs) were used as the primary effect size to estimate the outcome of overall tumor recurrence, recurrence in bladder neck/prostatic fossa.

RESULTS

In six eligible clinical trials, 483 patients were treated with simultaneous resection and 500 with TURBT alone. Within the follow-up period, tumor recurrence developed in 203 (42%) patients in the simultaneous resection group and 256 (51.2%) patients in the control group. The combined analysis indicated that the recurrence rate in the simultaneous resection group was statistically significantly lower than in the control group in the overall pooled data (combined OR = 0.67; 95% CI 0.52 to 0.88, P = 0.003). Tumor recurrence of bladder neck/prostatic fossa developed in 37(7.7%) patients in the simultaneous resection group and 42 (8.4%) patients in the control group. No statistically significant difference was found between the two groups (combined OR = 0.92; 95% CI 0.57 to 1.49, P = 0.74). Potential confounders, such as mean age, mean follow-up duration, multiplicity of tumor, and year of publication did not significantly influence the results.

CONCLUSION

There was at least the evidence that simultaneous TURBT/TURP did not increase the overall recurrence rate and recurrence rate in bladder neck/prostatic fossa. Simultaneous TURBT/TURP might be preferable for patients with NMIBC and BPH.
