Anxiety and Depression in Patients with Prostate Cancer, at Cancer Diagnosis and after a One-Year Follow-Up.

Prostate cancer (PCa) is the most prevalent among men, and psychological symptoms may affect many patients. This study aims to describe the prevalence of probable anxiety and depression before PCa treatments and after one year and to identify sociodemographic and clinical factors associated with these outcomes. Between February 2018 and March 2020, 292 patients recently diagnosed with PCa were recruited at the Instituto Português de Oncologia-Porto. The Hospital Anxiety and Depression Scale (HADS) was used to define probable anxiety and depression (cutoff = 11). The prevalence of probable anxiety remained stable from baseline to one year (7.8% vs. 8.5%, p = 0.866) while there was an increase in probable depression (3.1% vs. 6.8%, p = 0.012). After one year, probable depression persisted in 55.6% of patients with probable depression at baseline and 47.8% of those with probable anxiety at the first assessment had normal anxiety scores. At baseline, anxiety was more frequent among dwellers in rural areas (adjusted odds ratio-aOR, 95%CI: 2.80, 0.91-8.58) and less frequent in patients with body mass index 25-29.9 kg/m2 (aOR, 95%CI: 0.33, 0.12-0.91) compared to 18.5-24.9 Kg/m2, while those living alone had higher odds of depression (aOR, 95%CI: 6.35, 1.43-28.30). The frequency of anxiety and depression fluctuated during the course of treatment. Monitoring these symptoms would identify the most affected patients, contributing for a better use of mental health services.

Trends in breast and prostate cancer screening and diagnostic procedures during the COVID-19 pandemic in central Massachusetts.

PURPOSE: We calculated rates of breast and prostate cancer screening and diagnostic procedures performed during the COVID-19 pandemic through December 2021 compared to the same months in 2019 in a large healthcare provider group in central Massachusetts. METHODS: We included active patients of the provider group between January 2019 and December 2021 aged 30-85 years. Monthly rates of screening mammography and digital breast tomosynthesis, breast MRI, total prostate specific antigen (PSA), and breast or prostate biopsy per 1,000 people were compared by year overall, by age, and race/ethnicity. Completed procedures were identified by relevant codes in electronic health record data. RESULTS: Rates of screening mammography, tomosynthesis, and PSA testing reached the lowest levels in April-May 2020. Breast cancer screening rates decreased 43% in March and 99% in April and May 2020, compared to 2019. Breast cancer screening rates increased gradually beginning in June 2020 through 2021, although more slowly in Black and Hispanic women and in women aged 75-85. PSA testing rates decreased 34% in March, 78% in April, and 53% in May 2020, but rebounded to pre-pandemic levels by June 2020; trends were similar across groups defined by age and race/ethnicity. CONCLUSION: The observed decline in two common screening procedures during the COVID-19 pandemic reflects the impact of the pandemic on cancer early detection and signals potential downstream effects on the prognosis of delayed cancer diagnoses. The slower rate of return for breast cancer screening procedures in certain subgroups should be investigated to ensure all women return for routine screenings.

The effect of COVID-19 on prostate cancer testing in Australia.

AIM: The effects of the COVID-19 pandemic on healthcare in Australia have yet to be fully determined. There are well documented decreases in the rates of screening and diagnostic testing for many cancers in 2020, with commensurate stage migration of cancers when they are eventually detected. We aimed to determine whether there was a decrease in the rate of prostate cancer (PC) screening and testing in Australia in 2020. METHOD: Data was extracted from the Department of Human Services (DHS) website for Medicare Benefits Schedule (MBS) item numbers for tests pertinent to detection of Prostate Cancer. This data is de-identified and publicly available. Data was analysed at both a national, and a state level. RESULTS: For 2020 nationwide the percentage change for prostate cancer testing was minor with 97% as many PSA tests, 99% as many prostate MRIs, and 105% as many prostate biopsies as the average for the preceding years. The differences were not significant (PSA tests p = 0.059 and prostate biopsies p = 0.109). The predicted values are fairly similar to both the average values for the preceding 5 years and the actual number of tests done in 2020. With exception of PSA tests in Victoria the actual number of tests performed was within the 95% Prediction Interval (performed: 167,426; predicted 171,194-196,699; p = 0.015). CONCLUSION: The current pandemic has had a widespread reach across Australia, with varying impact across each state and territory. Contrary to the trends across the world, our data suggest that during 2020 in Australia most areas remained unaffected in terms of prostate cancer testing excluding Victoria, which had statistically significant decrease in the number of PSA tests correlating with the extended lockdown that occurred in the state.

Strengthening Capacity for Prostate Cancer Early Diagnosis in West Africa Amidst the COVID-19 Pandemic: A Realist Approach to Rethinking and Operationalizing the World Health Organization 2017 Guide to Cancer Early Diagnosis.

Two years after SARS-CoV-2 (COVID-19) was declared a global public health emergency, the restoration, at least, to the pre-pandemic level of early diagnostic services for prostate cancer has remained enormously challenging for many health systems, worldwide. This is particularly true of West Africa as the region grapples also with the broader impacts of changing demographics and overly stretched healthcare systems. With the lingering COVID-19 crisis, it is likely that the current trend of late prostate cancer diagnosis in the region will worsen with a concomitant increase in the burden of the disease. There is, therefore, a compelling need for innovative and evidence-based solutions to de-escalate the current situation and forestall the collapse of existing structures supporting early prostate cancer diagnosis in the region. In this viewpoint, we make a case for the operationalization of the World Health Organization (WHO) guide to early cancer diagnosis to strengthen the capacity for early prostate cancer diagnosis in West Africa using a realist approach, drawing on participatory health research and evidence-based co-creation. Ultimately, we demonstrate the potential for developing COVID-19 responsive and context-specific models to optimize patient navigation/journey along the essential steps of the World Health Organization guide to early cancer diagnosis.

The Impact of the Ongoing COVID-19 Epidemic on the Increasing Risk of Adverse Pathology in Prostate Cancer Patients Undergoing Radical Prostatectomy.

We aimed to assess whether the ongoing course of the COVID-19 epidemic has been associated with an increased risk of adverse pathology (AP) findings in prostate cancer (PC) patients treated with radical prostatectomy (RP). We performed a retrospective data analysis which included 408 consecutive, non-metastatic, previously untreated PC patients who underwent RP in our institution between March 2020 and September 2021. Patients were divided into two equally numbered groups in regard to the median surgery date (Early Epidemic [EE] and Late Epidemic [LE]) and compared. Adverse pathology was defined as either grade group (GG) ≥ 4, pT ≥ 3a or pN+ at RP. Patients in the LE group demonstrated significantly higher rates of AP than in the EE group (61 vs. 43% overall and 50 vs. 27% in preoperative non-high-risk subgroup, both p < 0.001), mainly due to higher rates of upgrading. On multivariable analysis, consecutive epidemic week (odds ratio: 1.02, 95% confidence interval: 1.00-1.03, p = 0.009) as well as biopsy GG ≥ 2 and a larger prostate volume (mL) were associated with AP in non-high-risk patients. The study serves as a warning call for increased awareness of risk underassessment in contemporarily treated PC patients.

Association of the COVID-19 Pandemic With Rates of Prostate Cancer Biopsies and Diagnoses in Black vs White US Veterans.

Importance: Several studies have assessed the negative effect of the COVID-19 pandemic on cancer screening and diagnosis rates. However, this has not been evaluated for prostate biopsy and prostate cancer (PC) diagnosis in an equal-access health care system. Objective: To determine the association of the pandemic with prostate biopsy and PC diagnosis rates among Black vs White patients in the Veterans Affairs Health Care System (VAHCS). Design, Setting, and Participants: This cohort study included a retrospective analysis of all prostate biopsies performed on patients in the VAHCS without a preexisting PC diagnosis between January 2018 and March 2021. The base population included all living male patients who had at least 1 visit to the VAHCS during the 3 years prior to each month of the study. Exposure: The COVID-19 pandemic. Main Outcomes and Measures: The main outcomes were the number of prostate biopsies and PC diagnoses by month. The influence of the pandemic on prostate biopsy volume and the incidence of PC diagnoses was modeled using an interrupted time-series analysis. Poisson generalized linear models were fitted to project the expected number of prostate biopsies and PC diagnoses had there been no pandemic interruption. Additional models were used to test for differences by race. Results: Prior to the pandemic (January 2018 through February 2020), monthly biopsy numbers among 51 606 included men ranged between 1230 and 1695, of which 56% to 60% of results were positive for PC. The estimated number of missed PC diagnoses from March 2020 through March 2021 ranged from 97 cases (October 2020: 752 cases expected, 655 cases observed) to 573 cases (April 2020: 794 cases expected, 221 cases observed). Prior to the pandemic, biopsy rates were statistically significantly higher among Black vs White men (incidence rate ratio, 2.25; 95% CI, 2.06-2.46; P < .001). There was no change in biopsy rates associated with race at the onset of the pandemic nor during the recovery period from March 2020 to March 2021. Similar trends were observed for PC diagnosis rates. Conclusions and Relevance: Results of this cohort study demonstrate that during the COVID-19 pandemic, prostate biopsy and PC diagnosis rates decreased, particularly during the peak of the pandemic. However, there were no statistically significant changes in rates by race.

Impact of the COVID-19 outbreak on prostate cancer care in the Netherlands.

INTRODUCTION: The COVID-19 outbreak has affected care for non-COVID diseases like cancer. We evaluated the impact of the COVID-19 outbreak on prostate cancer care in the Netherlands. METHODS: Prostate cancer diagnoses per month in 2020-2021 versus 2018-2019 were compared based on preliminary data of the Netherlands Cancer Registry (NCR) and nationwide pathology network. Detailed data was retrieved from the NCR for the cohorts diagnosed from March-May 2020 (first COVID-19 wave) and March-May 2018-2019 (reference). Changes in number of diagnoses, age, disease stage and first-line treatment were compared. RESULTS: An initial decline of 17% in prostate cancer diagnoses during the first COVID-19 wave was observed. From May onwards the number of diagnoses started to restore to approximately 95% of the expected number by the end of 2020. Stage at diagnosis remainedstable over time. In low-risk localised prostate cancer radical prostatectomy was conducted more often in week 9-12 (21% versus 12% in the reference period; OR=1.9, 95% CI; 1.2-3.1) and less active surveillance was applied (67% versus 78%; OR=0.6, 95% CI; 0.4-0.9). In the intermediate-risk group, a similar change was observed in week 13-16. Radical prostatectomy volumes in 2020 were comparable to 2018-2019. CONCLUSION: During the first COVID-19 wave the number of prostate cancer diagnoses declined. In the second half of 2020 this largely restored although the number remained lower than expected. Changes in treatment were temporary and compliant with adapted guidelines. Although delayed diagnoses could result in a less favourable stage distribution, possibly affecting survival, this seems not very likely.

Increasing the uptake in a general practice prostate cancer screening programme.

BACKGROUND: Prostate cancer (PC) is the second most common cause of cancer deaths among males worldwide. Prostate-specific antigen (PSA) is a predictive indicator of prostate pathology. Men with elevated PSA levels are at increased risk of developing PC. There is currently no UK national PC screening programme, therefore patients often present to general practices (GPs) at later stages of pathology, worsening patient prognosis and outcomes. LOCAL PROBLEM: The location of the GP surgery had a large patient population at increased risk of PC, namely Afro-Caribbean/Asian males. METHODS: We conducted baseline measurements to identify male patients over the age of 65 and/or male patients who were at high risk of developing PC. These included previous referred patients or patients with a PSA over 10.0. We then implemented three plan-do-study-act (PDSA) cycles and measured their effect after 2 weeks of starting the respective intervention. INTERVENTIONS: PDSA1: Generating a list of target patients who have not had repeat/follow-up/referral and directly contacting by telephone to invite them for a blood test.PDSA2: Creating patient-specific electronic pop-up reminders on the electronic-patient-record system for PSA follow-up/referral/repeat test.Planned PDSA3: Patient education of prostate health and general self-checking, as well as benefits/risks of undergoing PSA screening in the form of patient focus groups and informative leaflets. RESULTS: We identified 220 male patients over 65 registered at a large South London GP surgery. 77.7% of eligible patients had a PSA measurement since 1 April 2019. Our results showed an overall increase in screening of 13.5% from baseline. CONCLUSIONS: Our project identified patients that may potentially have undiagnosed prostate pathology. However, a key factor for not reaching our goal was blood test refusal. This was further exacerbated by the COVID-19 pandemic, impacting the capacity to disseminate appropriate information to the local population on the importance of PSA screening.

Managing advanced prostate cancer in the Asia Pacific region: "Real-world" application of Advanced Prostate Cancer Consensus Conference 2019 statements.

AIM: The second Asia-Pacific Advanced Prostate Cancer Consensus Conference (APAC APCCC 2020) gathered insights into the real-world application in the Asia-Pacific (APAC) region of consensus statements from the 3rd Advanced Prostate Cancer Consensus Conference (APCCC 2019). METHODS: The 4-h our virtual meeting in October 2020 brought together 26 experts from 14 APAC countries to discuss APCCC 2019 recommendations. Presentations were prerecorded and viewed prior to the meeting. A postmeeting survey gathered views on current practice. RESULTS: The meeting and survey highlighted several developments since APAC APCCC 2018. Increased access and use in the region of PSMA PET/CT imaging is providing additional diagnostic and staging information for advanced prostate cancer and influencing local and systemic therapy choices. Awareness of oligometastatic disease, although not clearly defined, is increasing. Novel androgen receptor pathway antagonists are expanding treatment options. Cost and access to contemporary treatments and technologies continue to be a significant factor influencing therapeutic decisions in the region. With treatment options increasing, multidisciplinary treatment planning, shared decision making, and informed choice remain critical. A discussion on the COVID-19 pandemic highlighted challenges for diagnosis, treatment, and clinical trials and new service delivery models that will continue beyond the pandemic. CONCLUSION: APAC-specific prostate cancer research and data are important to ensure that treatment guidelines and recommendations reflect local populations and resources. Facilitated approaches to collaboration across the region such as that achieved through APAC APCCC meetings continue to be a valuable mechanism to ensure the relevance of consensus guidelines within the region.

Impact of the COVID-19 pandemic on the diagnosis and treatment of men with prostate cancer.

OBJECTIVE: To determine the impact of the COVID-19 pandemic on diagnostic and treatment activity in 2020 across hospital providers of prostate cancer (PCa) care in the English National Health Service. METHODS: Diagnostic and treatment activity between 23 March (start of first national lockdown in England) and 31 December 2020 was compared with the same calendar period in 2019. Patients newly diagnosed with PCa were identified from national rapid cancer registration data linked to other electronic healthcare datasets. RESULTS: There was a 30.8% reduction (22 419 vs 32 409) in the number of men with newly diagnosed PCa in 2020 after the start of the first lockdown, compared with the corresponding period in 2019. Men diagnosed in 2020 were typically at a more advanced stage (Stage IV: 21.2% vs 17.4%) and slightly older (57.9% vs 55.9% ≥ 70 years; P < 0.001). Prostate biopsies in 2020 were more often performed using transperineal (TP) routes (64.0% vs 38.2%). The number of radical prostatectomies in 2020 was reduced by 26.9% (3896 vs 5331) and the number treated by external beam radiotherapy (EBRT) by 14.1% (9719 vs 11 309). Other changes included an increased use of EBRT with hypofractionation and reduced use of docetaxel chemotherapy in men with hormone-sensitive metastatic PCa (413 vs 1519) with related increase in the use of enzalutamide. CONCLUSION: We found substantial deficits in the number of diagnostic and treatment procedures for men with newly diagnosed PCa after the start of the first lockdown in 2020. The number of men diagnosed with PCa decreased by about one-third and those diagnosed had more advanced disease. Treatment patterns shifted towards those that limit the risk of COVID-19 exposure including increased use of TP biopsy, hypofractionated radiation, and enzalutamide. Urgent concerted action is required to address the COVID-19-related deficits in PCa services to mitigate their impact on long-term outcomes.

Association Between Androgen Deprivation Therapy and Mortality Among Patients With Prostate Cancer and COVID-19.

Importance: Androgen deprivation therapy (ADT) has been theorized to decrease the severity of SARS-CoV-2 infection in patients with prostate cancer owing to a potential decrease in the tissue-based expression of the SARS-CoV-2 coreceptor transmembrane protease, serine 2 (TMPRSS2). Objective: To examine whether ADT is associated with a decreased rate of 30-day mortality from SARS-CoV-2 infection among patients with prostate cancer. Design, Setting, and Participants: This cohort study analyzed patient data recorded in the COVID-19 and Cancer Consortium registry between March 17, 2020, and February 11, 2021. The consortium maintains a centralized multi-institution registry of patients with a current or past diagnosis of cancer who developed COVID-19. Data were collected and managed using REDCap software hosted at Vanderbilt University Medical Center in Nashville, Tennessee. Initially, 1228 patients aged 18 years or older with prostate cancer listed as their primary malignant neoplasm were included; 122 patients with a second malignant neoplasm, insufficient follow-up, or low-quality data were excluded. Propensity matching was performed using the nearest-neighbor method with a 1:3 ratio of treated units to control units, adjusted for age, body mass index, race and ethnicity, Eastern Cooperative Oncology Group performance status score, smoking status, comorbidities (cardiovascular, pulmonary, kidney disease, and diabetes), cancer status, baseline steroid use, COVID-19 treatment, and presence of metastatic disease. Exposures: Androgen deprivation therapy use was defined as prior bilateral orchiectomy or pharmacologic ADT administered within the prior 3 months of presentation with COVID-19. Main Outcomes and Measures: The primary outcome was the rate of all-cause 30-day mortality after COVID-19 diagnosis for patients receiving ADT compared with patients not receiving ADT after propensity matching. Results: After exclusions, 1106 patients with prostate cancer (before propensity score matching: median age, 73 years [IQR, 65-79 years]; 561 (51%) self-identified as non-Hispanic White) were included for analysis. Of these patients, 477 were included for propensity score matching (169 who received ADT and 308 who did not receive ADT). After propensity matching, there was no significant difference in the primary end point of the rate of all-cause 30-day mortality (OR, 0.77; 95% CI, 0.42-1.42). Conclusions and Relevance: Findings from this cohort study suggest that ADT use was not associated with decreased mortality from SARS-CoV-2 infection. However, large ongoing clinical trials will provide further evidence on the role of ADT or other androgen-targeted therapies in reducing COVID-19 infection severity.

Patterns of Prostate-Specific Antigen Testing and Prostate Biopsies During the COVID-19 Pandemic.

PURPOSE: This study examined changes in prostate disease screening (prostatic-specific antigen [PSA] testing), prostate biopsy testing, and prostate cancer diagnoses during the COVID-19 pandemic through December 2020. MATERIALS AND METHODS: This analysis included test results from men ≥ 40 years, without prior International Classification of Diseases-10 record of prostate cancer since January 2016, who received PSA or prostate biopsy testing at Quest Diagnostics during January 2018-December 2020. Monthly trends were evaluated for three periods: prepandemic (January 2018-February 2020), early-pandemic (March-May 2020), and late-pandemic (June-December 2020). RESULTS: Meeting inclusion criteria were 16,365,833 PSA and 48,819 prostate biopsy results. The average monthly number of PSA tests declined from 465,187 prepandemic to 295,786 early-pandemic (36.4% decrease; P = .01) before rebounding to 483,374 (3.9% increase; P = .23) late-pandemic. The monthly average number of PSA results ≥ 50 ng/mL (23,356; 0.14% of all PSA results) dipped from 659 prepandemic to 506 early-pandemic (23.2% decrease; P = .02) and rebounded to 674 late-pandemic (2.3% increase; P = .65). The average monthly number of prostate biopsy results decreased from 1,453 prepandemic to 903 early-pandemic (37.9% decrease; P = .01) before rebounding to 1,190 late-pandemic (18.1% decrease; P = .01). The average monthly number for Gleason score ≥ 8 (6,241; 12.8% of all prostate biopsies) declined from 182 prepandemic to 130 early-pandemic (28.6% decrease; P = .02) and decreased to 161 late-pandemic (11.5% decrease; P = .02). CONCLUSION: The findings suggest that a substantial number of prostate screening opportunities and cancer diagnoses have been missed. Efforts are needed to bring such patients back for screening and diagnostic testing and to restore appropriate care for non-COVID-19-related medical conditions.

Frequency and Risk Factors of Sleep Disturbances in Patients With Prostate Cancer Assigned to Local or Loco-regional Radiotherapy.

BACKGROUND/AIM: Many patients with prostate cancer receive definitive or adjuvant radiotherapy. This study aimed to identify the frequency of sleep disturbances and corresponding risk factors prior to radiation treatment. PATIENTS AND METHODS: Data of 48 patients assigned to local or loco-regional irradiation for prostate cancer were retrospectively analyzed for pre-radiotherapy sleep disturbances. Fifteen characteristics were analyzed including age, performance status, comorbidity, history of previous malignancy, distress score, (emotional, physical or practical) problems, prostate-specific antigen, primary tumor stage, Gleason-score, upfront androgen deprivation therapy (ADT), treatment volume, brachytherapy, and COVID-19 pandemic. RESULTS: Pre-radiotherapy sleep disturbances were reported by 20.8% of patients and significantly associated with distress scores ≥4 (p<0.0001) and ≥3 physical problems (p=0.0001). Trends were found for Karnofsky performance score ≤80 (p=0.095), Gleason score 7b-9 (p=0.079), and ADT (p=0.067). CONCLUSION: Pre-radiotherapy sleep disturbances were less common in prostate cancer patients than in other cancer patients. Risk factors were identified that can help identify patients requiring psychological support prior to radiotherapy.

COVID-19 pandemic impact on uro-oncological disease outcomes at an Italian tertiary referral center.

PURPOSE: To assess differences in referral and pathologic outcomes for uro-oncology cases prior to and during the COVID pandemic, comparing clinical and pathological data of cancer surgeries performed at an academic referral center between 2019 and 2020. METHODS: We collected data of 880 prostate biopsies, 393 robot-assisted radical prostatectomies (RARP) for prostate cancer (PCa), 767 trans-urethral resections of bladder tumor (TURB) and 134 radical cystectomies (RC) for bladder cancer (BCa), 29 radical nephro-ureterectomies (RNU) for upper tract urothelial carcinoma, 130 partial nephrectomies (PN) and 12 radical nephrectomies (RN) for renal cancer, and 41 orchifunicolectomies for testicular cancer. Data of patients treated in 2019 (before COVID-19 pandemic) were compared to patients treated in 2020 (during pandemic). RESULTS: No significant decline in uro-oncological surgical activity was seen between 2019 and 2020. No significant increase in time between diagnosis and surgery was observed for all considered cancers. No differences in terms of main pathologic features were observed in patients undergoing RARP, TURB, RNU, RN/PN, or orchifunicolectomy. A higher proportion of ISUP grade 3 and 4 PCa were diagnosed in 2020 at biopsy (p = 0.001), but this did not translate into worse pathological grade/stage at RARP. In 2020, more advanced disease features were seen after RC, including lymph node involvement (p = 0.01) and non-organ confined disease (p = 0.02). CONCLUSION: Neither decline in uro-oncologic activity nor delay between diagnosis and treatment was observed at our institution during the first year of COVID-19 pandemic. No significant worsening of cancer disease features was found in 2020 except for muscle-invasive BCa.

Influence of androgen deprivation therapy on the severity of COVID-19 in prostate cancer patients.

BACKGROUND: The TMPRSS2 protein has been involved in severe acute respiratory syndrome caused by coronavirus 2 (SARS-CoV-2). The production is regulated by the androgen receptor (AR). It is speculated that androgen deprivation therapy (ADT) may protect patients affected by prostate cancer (PC) from SARS-CoV-2 infection. METHODS: This is a retrospective study of patients treated for COVID-19 in our institution who had a previous diagnosis of PC. We analyzed the influence of exposure of ADT on the presence of severe course of COVID-19. RESULTS: A total of 2280 patients were treated in our center for COVID-19 with a worse course of disease in males (higher rates of hospitalization, intense care unit [ICU] admission, and death). Out of 1349 subjects registered in our PC database, 156 were on ADT and 1193 were not. Out of those, 61 (4.52%) PC patients suffered from COVID-19, 11 (18.0%) belonged to the ADT group, and 50 (82.0%) to the non-ADT group. Regarding the influence of ADT on the course of the disease, statistically significant differences were found neither in the death rate (27.3% vs. 34%; p = 0.481), nor in the presence of severe COVID-19: need for intubation or ICU admission (0% vs. 6.3%; p = 0.561) and need for corticoid treatment, interferon beta, or tocilizumab (60% vs. 34.7%; p = 0.128). Multivariate analysis adjusted for clinically relevant comorbidities did not find that ADT was a protective factor for worse clinical evolution (risk ratio [RR] 1.08; 95% confidence interval [CI], 0.64-1.83; p = 0.77) or death (RR, 0.67; 95% CI, 0.26-1.74; p = 0.41). CONCLUSIONS: Our study confirms that COVID-19 is more severe in men. However, the use of ADT in patients with PC was not shown to prevent the risk of severe COVID-19.

Genetic Susceptibility of ACE2 and TMPRSS2 in Six Common Cancers and Possible Impacts on COVID-19.

PURPOSE: Coronavirus disease 2019 (COVID-19) pandemic has spread worldwide rapidly and patients with cancer have been considered as a vulnerable group for this infection. This study aimed to examine the expressions of angiotensin-converting enzyme 2 (ACE2) and transmembrane serine protease 2 (TMPRSS2) in tumor tissues of six common cancer types. MATERIALS AND METHODS: The expression levels of ACE2 and TMPRSS2 in tumors and control samples were obtained from online databases. Survival prognosis and biological functions of these genes were investigated for each tumor type. RESULTS: There was the overexpression of ACE2 in colon and stomach adenocarcinomas compared to controls, meanwhile colon and prostate adenocarcinomas showed a significantly higher expression of TMPRSS2. Additionally, survival prognosis analysis has demonstrated that upregulation of ACE2 in liver hepatocellular carcinoma was associated with higher overall survival (hazard ratio, 0.65; p=0.016) and disease-free survival (hazard ratio, 0.66; p=0.007), while overexpression of TMPRSS2 was associated with a 26% reduced risk of death in lung adenocarcinoma (p=0.047) but 50% increased risk of death in breast invasive carcinoma (p=0.015). CONCLUSION: There is a need to take extra precautions for COVID-19 in patients with colorectal cancer, stomach cancer, and lung cancer. Further information on other types of cancer at different stages should be investigated.
