Transurethral prostate surgery in prostate cancer patients: A population-based comparative analysis of complication and mortality rates

Objective

Prostate cancer (PCa) patients might experience lower urinary tract symptoms as those diagnosed with benign prostatic hyperplasia (BPH). Some of them might be treated for their lower urinary tract symptoms instead of PCa. We aimed to test the effect of PCa versus BPH on surgical outcomes after transurethral prostate surgery, namely complication and mortality rates.

Methods

Within the American College of Surgeons National Surgical Quality Improvement Program database (2011-2016), we identified patients who underwent transurethral resection of the prostate, photoselective vaporization, or laser enucleation. Patients were stratified according to postoperative diagnosis (PCa vs. BPH). Univariable and multivariable logistic regression models evaluated the predictors of perioperative morbidity and mortality. A formal test of interaction between diagnosis and surgical technique used was performed.

Results

Overall, 34 542 patients were included. Of all, 2008 (5.8%) had a diagnosis of PCa. The multivariable logistic regression model failed to show statistically significant higher rates of postoperative complications in PCa patients (odds ratio: 0.9, 95% confidence interval: 0.7-1.1; p=0.252). Moreover, similar rates of perioperative mortality (p=0.255), major acute cardiovascular events (p=0.581), transfusions (p=0.933), and length of stay of more than or equal to 30 days (p=0.174) were found. Additionally, all tests failed to show an interaction between post-operative diagnosis and surgical technique used.

Conclusion

Patients diagnosed with PCa do not experience higher perioperative morbidity or mortality after transurethral prostate surgery when compared to their BPH counterparts. Moreover, the diagnosis seems to not influence surgical technique outcomes.

Perioperative major acute cardiovascular events after 180-W GreenLight laser photoselective vaporization of the prostate

BACKGROUND

Major acute cardiovascular events (MACE) prevalence after 180-W GreenLight (180-W GL) laser photoselective vaporization (PVP) have never been explored. Aim of our study is to evaluate perioperative MACE that occurred concomitantly with 180-W GL PVP.

MATERIALS AND METHODS

We relied on a multi-institutional database that included 14 centers. Data from 923 patients who underwent 180-W GL PVP were reviewed. We abstracted pre- and perioperative data of patients who experienced perioperative MACE, such as angina pectoris, acute myocardial infarction, other chronic ischemic heart disease, transient ischemic attack, or cerebrovascular accident as well as deep venous thrombosis with or without pulmonary embolism. We relied on a case-series format to report the main findings of our analyses.

RESULTS

18 (1.9%) patients reported MACE in 7 centers. Median age was 69.5 (IQR 66.0-79.2) years. Of all, 7 patients underwent standard PVP and 11 anatomical PVP. Eleven patients (61.1%) were not under anticoagulant/antiplatelet treatment, 6 (33.3%) were under low dose aspirin, and 1 (5.6%) was under clopidogrel. Four patients (22.2%) had an instrumental and laboratory diagnosis of myocardial infarction, 7 (38.9%) had an episode of angina pectoris with or without rhythm alteration, 3 (16.7%) reported symptomatic deep venous thrombosis, and 4 (22.2%) had other MACE-like events.

CONCLUSIONS

Physician should take in consideration the possibility of MACE or MACE-like events. The real MACE rate may be different as only half of included centers reported MACE. Since the main target of laser surgery are high-risk bleeding patients, prospective observational trials focused on detection of these possible complications are warranted.
