Abstract

Background: The coronavirus disease 2019 (COVID-19) pandemic has affected care for diseases like cancer. The aim was to evaluate the impact of COVID-19 on waiting times for diagnosis and treatment of prostate cancer (PC), as well as the possible effect on the treatment results in PC patients undergoing radical prostatectomy.

Methods: We compared the results of 497 patients who underwent biopsy prior to the COVID-19 pandemic (1 January-31 December 2019) with those of 290 patients biopsied during the COVID-19 pandemic (1 January-31 December 2020). Demographic data, tumour characteristics, type of treatment and diagnosis times were comparable. Prostate specific antigen (PSA) levels were recorded at consultation prior to biopsy and after treatment. Mann-Whitney and chi-square tests were used to compare continuous variables and percentages, respectively.

Results: In 2020, there were fewer urology consultations (35,160 vs. 40,225 in 2019). The median PSA in 2020 was significantly higher (14.3 vs. 9.9 ng/dL in 2019). In 2019, 53.1% (N=264) of the biopsies were positive for cancer vs. 47.2% (N=137) in 2020 (P=0.104). In 2020, more patients presented with metastatic disease (7.3% vs. 1.9%, P=0.009). Also, in 2020 there was a longer waiting time for prostate biopsy (42.1 vs. 35.3 days in 2019, P=0.019). A total of 132 patients underwent laparoscopic radical prostatectomy (LARP). The median time until surgery was similar in both years (71.9 vs. 58.29 days). During 2020, a higher percentage of patients had ISUP grade 4 in the surgical specimen (34.3% vs. 17.5%, P=0.07). Furthermore, a higher percentage of aggressive (pT3) tumours were diagnosed (37.2% vs. 27.2%, P=0.08), and the percentage of patients with involvement of surgical margins was also higher (48.6% vs. 29.3%, P=0.027). There were no differences between the groups in terms of biochemical recurrence or persistent PSA at one year (P=0.711).

Conclusions: Delayed biopsy during the COVID-19 period did not appear to adversely impact biopsy results. Patients biopsied in 2020 had higher PSA, possibly due to proper triaging. A higher rate of adverse pathology outcomes was observed in patients undergoing radical prostatectomy during the pandemic, probably due to understaging of the biopsy. This study serves to raise awareness of the risk of deterioration of care of PC patients due to possible underdiagnosis.
