Impact of the COVID-19 Pandemic on Urologic Oncology Surgery: Implications for Moving Forward

COVID-19 Pandemic Impact on Uro-Oncological Disease Outcomes at a German Referral Center

INTRODUCTION

To assess differences in referral and pathologic outcomes for uro-oncology cases prior to, during, and after the COVID-19 pandemic, comparing clinical and pathological data from cancer surgeries performed at a university medical center between 2018 and 2023.

METHODS

We collected data of 212 patients with radical prostatectomy (RP) for prostate cancer, 157 patients with radical cystectomies (RCs) for bladder cancer, 36 patients with radical nephroureterectomies (RNUs) for upper tract urothelial carcinoma, 133 patients with partial nephrectomies (PNs), and 160 patients with radical nephrectomies (RNs) for renal cancer, 93 patients with orchifunicolectomy for testicular cancer, 39 patients with newly diagnosed penile cancer. Data from patients treated between 2018 and February 2020 (before the COVID-19 pandemic) were compared with data from patients treated between March 2020 and March 2022 (during the COVID-19 pandemic) and between April 2022 and February 2023 (after the COVID-19 pandemic).

RESULTS

No differences in terms of main pathologic features were observed in patients undergoing RP, RNU, orchifunicolectomy, or circumcision and/or penectomy. Further, a lower pathological tumor stage was diagnosed for RN after the COVID-19 pandemic (p < 0.05). A higher age at diagnosis for penile cancer was observed during the pandemic cohort in comparison to the pre-COVID-19 pandemic cohort (p < 0.05), but this did not translate into a worse pathological stage or lymph node involvement. Another notable change was the shortening of the length of stay (LOS) for orchifunicolectomy over the pandemic (p < 0.05).

CONCLUSION

Neither decline in uro-oncologic activity nor pathological features were observed at our institution before, during, and after the COVID-19 pandemic. A significantly lower pathological tumor stage for RN after the COVID-19 pandemic was seen. Penile cancer was diagnosed at a significantly higher age during the COVID-19 pandemic, and a decrease in LOS for orchifunicolectomy was observed.

TRENDS IN SURGICAL MANAGEMENT OF RENAL NEOPLASMS: SINGLE CENTER RESULTS IN THE LAST DECADE

The majority of renal neoplasms can be treated surgically using open or minimally-invasive approach. Nephron-sparing surgery should be used when possible, regardless to the operative approach. In this retrospective study, we analyzed surgical trends of operative treatment of renal neoplasms in the period from February 2011 until December 2020. There were a total of 1031 procedures, 703 (68.2%) radical nephrectomies (RN) and 328 (31.8%) partial nephrectomies (PN). Laparoscopic approach was used in 211 (20.5%) (111 PN and 100 RN), while open approach was used in 820 (79.5%) (328 PN and 703 RN) cases. There were 12 procedures performed with the use of cardiopulmonary bypass and hypothermic arrest. The median operative time was 161 minutes for open RN and 158 for open PN, 160 for laparoscopic RN, and 162 for laparoscopic PN. The most common pathology was clear cell carcinoma in 693 (67.3%), papillary carcinoma in 115 (11.2%), chromophobe carcinoma in 67 (6.5%), oncocytoma in 46 (4.5%), and angiomyolipoma in 33 (3.2%) patients. Pathologically, pT1 stage was diagnosed in 56.9%, pT2 in 5.8%, pT3 in 22.4% and pT4 in 1.2% of patients. Regional lymphadenectomy was performed in 354 (34.3%) patients, among which lymph nodes were positive in 40 (11.3%) cases. Surgical margins were positive in 27 cases when PN was performed (8.2%). In conclusion, there was an ongoing raising trend in the number of procedures in general, and also in minimally invasive and nephron-sparing surgery in our study.

Impact of COVID-19 pandemic on older cancer patients: Proposed solution by the International Geriatric Radiotherapy Group

Older cancer patients are disproportionally affected by the Coronavirus 19 (COVID-19) pandemic. A higher rate of death among the elderly and the potential for long-term disability have led to fear of contracting the virus in these patients. This fear can, paradoxically, cause delay in diagnosis and treatment that may lead to a poor outcome that could have been prevented. Thus, physicians should devise a policy that both supports the needs of older patients during cancer treatment, and serves to help them overcome their fear so they seek out to cancer diagnosis and treatment early. A combination of telemedicine and a holistic approach, involving prayers for older cancer patients with a high level of spirituality, may improve vaccination rates as well as quality of life during treatment. Collaboration between health care workers, social workers, faith-based leaders, and cancer survivors may be crucial to achieve this goal. Social media may be an important component, providing a means of sending the positive message to older cancer patients that chronological age is not an impediment to treatment.

Can We Identify Patients in Danger of Delayed Treatment? Management of COVID-19 Pandemic Backlog in Urology Care in Poland

The COVID-19 pandemic had a tremendous impact on healthcare systems around the world. This study aims to research the course of surgical treatment in urology during the pandemic in 2020, evaluate the volume of deferred treatment in urology in Poland, and indicate groups of patients that are especially vulnerable to a delay in the delivery of healthcare services. The National Health Found statistics (NHF) database was searched for information on procedures completed in urology departments from 2015 to 2020. Changes in hospital discharges of adults from 2019 to 2021 were investigated using monthly reports of NHF on patient billing groups. Statistics of PSA, testosterone, and creatinine testing were extracted from NHF reports. Annual changes in the number of surgeries were calculated. Then, the estimation of the expected quantity of procedures without the occurrence of the pandemic was performed using linear regression based on data from 2015 to 2020. The estimation was assumed reliable at R² > 0.8. The difference between collected and estimated data was analysed. In 2020, the volume of radical prostatectomies, cystectomies, and kidney surgeries noted downturns following lockdowns in March and November. All analysed procedures, except radical cystectomy, noted a reduction in the entire year. The declines reached -34% in shockwave lithotripsy, -13% in ureterorenoscopic lithotripsy, -22% in cystolithotripsy, -28% in percutaneous lithotripsy, -12% in transurethral resection of a bladder tumour (TURBT), -31% in transurethral resection of the prostate, -15% in nephrectomy and kidney tumorectomy, and -10% in radical prostatectomy. Among the analysed procedures, only radical cystectomy rates increased 5%. Prostate-specific antigen and creatinine tests fell -17%, and testosterone testing was down -18%. In conclusion, the patients most vulnerable to delayed treatment due to the post-pandemic backlog are those requiring TURBT, kidney cancer operations, and radical prostatectomies. Solving backlogs in urology should prioritise cancer patients and thus requires improved access to cystoscopy, TURBT, diagnoses and surgery of prostate and kidney tumours. Addressing the needs of patients suffering from benign diseases demands appropriate measures to increase the surgical productivity of urology departments.

Association between COVID-19 Burden, Population Vaccination Status, and Urologic Oncology Surgery Volume: A National Multicenter Cross-Sectional Study

Initial deleterious effects of the COVID-19 pandemic on urologic oncology surgeries are well described, but the possible influence of vaccination efforts and those of pandemic conditions on surgical volumes is unclear. Our aim was to examine the association between changing vaccination status and COVID-19 burden throughout the pandemic and the volume of urologic oncology surgeries in Israel. This multi-center cross-sectional study included data collected from five tertiary centers between January 2019 and December 2021. All 7327 urologic oncology surgeries were included. Epidemiological data were obtained from the Israeli Ministry of Health database. A rising trend in total urologic oncology surgery volumes was observed with ensuing COVID-19 wave peaks over time (X2 = 13.184, df = 3, p = 0.004). Total monthly surgical volumes correlated with total monthly hospitalizations due to COVID-19 (R = -0.36, p = 0.015), as well as with the monthly average Oxford Stringency Index (R = -0.31, p = 0.035). The cumulative percent of vaccinations and of new COVID-19 cases per month did not correlate with total monthly urologic surgery volumes. Our study demonstrates the gradual acclimation of the Israeli healthcare system to the COVID-19 pandemic. However, hospitalizations due to COVID-19, as well as restriction stringency, correlate with lower volumes of urologic oncological surgeries, regardless of the population's vaccination status.

Institutional Surgical Response and Associated Volume Trends Throughout the COVID-19 Pandemic and Postvaccination Recovery Period

Importance

The COVID-19 pandemic is associated with decreased surgical procedure volumes, but existing studies have not investigated this association beyond the end of 2020, analyzed changes during the post-vaccine release period, or quantified these changes by patient acuity.

Objective

To quantify changes in the volume of surgical procedures at a 1017-bed academic quaternary care center from January 6, 2019, to December 31, 2021.

Design, Setting, and Participants

In this cohort study, 129 596 surgical procedure volumes were retrospectively analyzed during 4 periods: pre-COVID-19 (January 6, 2019, to January 4, 2020), COVID-19 peak (March 15, 2020, to May 2, 2020), post-COVID-19 peak (May 3, 2020, to January 2, 2021), and post-vaccine release (January 3, 2021, to December 31, 2021). Surgery volumes were analyzed by subspecialty and case class (elective, emergent, nonurgent, urgent). Statistical analysis was by autoregressive integrated moving average modeling.

Main Outcomes and Measures

The primary outcome of this study was the change in weekly surgical procedure volume across the 4 COVID-19 periods.

Results

A total of 129 596 records of surgical procedures were reviewed. During the COVID-19 peak, overall weekly surgical procedure volumes (mean [SD] procedures per week, 406.00 [171.45]; 95% CI, 234.56-577.46) declined 44.6% from pre-COVID-19 levels (mean [SD] procedures per week, 732.37 [12.70]; 95% CI, 719.67-745.08; P < .001). This weekly volume decrease occurred across all surgical subspecialties. During the post-COVID peak period, overall weekly surgical volumes (mean [SD] procedures per week, 624.31 [142.45]; 95% CI, 481.85-766.76) recovered to only 85.8% of pre-COVID peak volumes (P < .001). This insufficient recovery was inconsistent across subspecialties and case classes. During the post-vaccine release period, although some subspecialties experienced recovery to pre-COVID-19 volumes, others continued to experience declines.

Conclusions and Relevance

This quaternary care institution effectively responded to the pressures of the COVID-19 pandemic by substantially decreasing surgical procedure volumes during the peak of the pandemic. However, overall surgical procedure volumes did not fully recover to pre-COVID-19 levels well into 2021, with inconsistent recovery rates across subspecialties and case classes. These declines suggest that delays in surgical procedures may result in potentially higher morbidity rates in the future. The differential recovery rates across subspecialties may inform institutional focus for future operational recovery.

The Impact of Surgical Waiting Time on Oncological Outcomes in Patients with Upper Tract Urothelial Carcinoma Undergoing Radical Nephroureterectomy: A Systematic Review

Radical nephroureterectomy (RNU) with bladder cuff excision is a standard of care in patients with high-risk upper tract urothelial carcinoma (UTUC). Although several recommendations and guidelines on the delayed treatment of urologic cancers exist, the evidence on UTUC is scarce and ambiguous. The present systematic review aimed to summarize the available evidence on the survival outcomes after deferred RNU in patients with UTUC. A systematic literature search of the three electronic databases (PubMed, Embase, and Cochrane Library) was conducted until 30 April 2022. Studies were found eligible if they reported the oncological outcomes of patients treated with deferred RNU compared to the control group, including those patients treated with RNU without delay. Primary endpoints were cancer-specific survival (CSS), overall survival (OS), and recurrence-free survival (RFS). In total, we identified seven eligible studies enrolling 5639 patients. Significant heterogeneity in the definition of “deferred RNU” was found across the included studies. Three out of five studies reporting CSS showed that deferring RNU was associated with worse CSS. Furthermore, three out of four studies reporting OS found a negative impact of delay in RNU on OS. One out of three studies reporting RFS found a negative influence of delayed RNU on RFS. While most studies reported a 3 month interval as a significant threshold for RNU delay, some subgroup analyses showed that a safe delay for RNU was less than 1 month in patients with ureteral tumors (UT) or less than 2 months in patients with hydronephrosis. In conclusion, long surgical waiting time for RNU (especially more than 3 months after UTUC diagnosis) could be considered as an important risk factor having a negative impact on oncological outcomes in patients with UTUC; however, the results of the particular studies are still inconsistent. The safe delay for RNU might be shorter in specific subsets of high-risk patients, such as those with UT and/or hydronephrosis at the time of diagnosis. High-quality additional studies are required to establish evidence for valid recommendations.

How Does the COVID-19 Pandemic Influence Histopathological Outcomes for Urologic Cancers?

Objective: The coronavirus disease 2019 (COVID-19) pandemic disrupted all routine health care services and resulted in a significant reconfiguration of urologic cancer services and care pathways across the globe. This study aimed to retrospectively determine the pandemic’s impact on the urologic oncological surgery outcomes at a high-volume referral center.

Materials and methods: We compared the number and histopathological outcomes of urologic oncological procedures in a referral center coded during the pandemic and data of the period before the pandemic as control. Data were extracted from patient files and hospital records. The pathological examination included a complete histopathological staging according to TNM stage.

Results: A total of 683 patients were included in the study, 424 (62%) of which were operated in the pre-pandemic period. There was a 39% decline in urologic oncological surgical activity in the pandemic, mostly in renal and prostate cancer. The mean tumor size was larger in renal cancer patients who underwent surgery during the pandemic (5.6 cm vs 4.5 cm, p=0.002). During the pandemic, more lymph node involvement was seen after radical cystectomy and prostatectomy (50% vs 27.8%, p=0.024 and 12.5% vs 4.5%, p=0.026, respectively). No differences in terms of main pathologic features were observed in patients undergoing radical orchiectomy.

Conclusion: COVID-19 appeared to adversely effect oncologic outcomes in patiens undergone surgery for prostate and bladder cancer. Tumor development induced by a delay in diagnosis may cause severe consequences for patients. Reprioritizion of non-deferrable urologic oncological seems crucial.
