Prognostic Impact of Each Item of the SARC-F Questionnaire in Patients Undergoing Major Surgery for Urologic Cancer.

We aimed to evaluate the association between scores on each item of the SARC-F questionnaire and life expectancy in patients undergoing major surgery for urologic cancer. This retrospective study included 1018 patients undergoing elective major urologic cancer surgery. All patients completed the SARC-F questionnaire preoperatively. Demographic and clinical data were collected. The primary endpoint was an association between SARC-F scores and overall survival (OS). Of the 1018 patients, the median age was 72 years and 920 (90%) were male. Multivariate analysis revealed four factors significantly and independently associated with shorter OS: assistance with walking score ≥1 (Hazard ratio: HR=2.18, P=0.044), cancer stages ≥ III (HR=7.98, P<0.001), high blood loss ≥78 ml or blood transfusion during surgery (HR=4.53, P=0.007 and HR=2.41, P=0.037, respectively). This study found that among the items of the SARC-F questionnaire, assistance with walking was a strong predictor of life expectancy. Incorporating such a simple screening tool into the preoperative assessment would help to ensure more appropriate perioperative care for urologic cancer patients.

Enterococci independently increase the risk for initial antibiotic treatment failure and prolonged hospitalization in adult patients with complicated urinary tract infection: a retrospective cohort study.

We aimed to investigate the impact of enterococci on initial antibiotic treatment (IAT) failure and prolonged hospitalization in complicated urinary tract infection (cUTI) cases, and to identify risk factors for enterococcal cUTI. Adult cUTI patients were analyzed to compare the differences between the Enterococcus and non-Enterococcus groups. Univariate and multivariate analyses were employed to identify independent risk factors. This study included 419 patients, with the Enterococcus group showing significantly higher IAT failure rates and an extended average length of stay by 4.4 days compared to the non-Enterococcus group. Multivariate analysis identified enterococci, hospital-acquired UTIs (HA-UTI), indwelling catheters, and bed rest (bedridden) as independent risk factors for IAT failure. Enterococci were notably linked to prolonged hospitalization, other independent risk factors included IAT failure, prior antimicrobial use, age-adjusted Charlson comorbidity index (ACCI) ≥ 4, hypoalbuminemia, and bed rest. Urological cancer, HA-UTI, indwelling catheters, urinary retention, and urologic surgery were risk factors for enterococcal cUTI. We provide the first evidence that enterococci independently increase the risk for IAT failure and prolonged hospitalization in adults with cUTIs, highlighting the significance of timely identification to optimize measures including antibiotic regimens. Risk factors for enterococcal cUTI have also been identified to aid clinicians in managing this condition.

The role of geriatric assessment in the care of older adults undergoing urologic cancer surgery.

Older adults undergoing urologic cancer surgery have unique needs and require unique risk assessment and management. This review will discuss recent literature on brief screening tools to identify high risk older adults in the preoperative period and the role of comprehensive geriatric assessment (CGA) in identifying and addressing geriatric vulnerabilities for older adults undergoing urologic cancer surgery. Frailty screening tools such as the G8 can be used to identify patients who are at an increased risk of adverse postoperative outcomes such as postoperative complications and prolonged length of stay. CGA can provide more detailed information about geriatric syndromes prior to urologic cancer surgery. Screening tools for geriatric vulnerabilities and CGA are valuable tools for the urologist in identifying high-risk older adults, counseling patients on perioperative risk and addressing vulnerabilities prior to surgery. Making health system-wide changes can allow this optimal practice to reach more older surgical patients.

Teaching Hospitals and Textbook Outcomes After Major Urologic Cancer Surgery

ObjectivesTo assess textbook outcomes by hospital teaching status follow major surgery for genitourinary malignancies. MethodsWe used 100% national Medicare Provider Analysis and Review files from 2017-2020 to assess rates of textbook outcomes in undergoing bladder (i.e., radical cystectomy), kidney (i.e., radical or partial nephrectomy), and prostate (i.e., radical prostatectomy) surgery for genitourinary malignancies. The extent of integration of learners into each hospital’s workforce—defined as major, minor and non- teaching—was the primary exposure. A textbook outcome, measured at the patient level, was defined as the absence of in-hospital mortality and mortality within 30 days of surgery, no readmission 30 days following discharge, no postoperative complication, and no prolonged length of stay. ResultsTextbook outcomes were achieved in 51% (8,564/16,786) of patients after bladder cancer surgery, 70% (39,938/57,300) of patients after kidney cancer surgery, and 82% (50,408/61,385) of patients after prostate cancer surgery. After adjusting for patient- and hospital-level characteristics, teaching hospitals had higher rates of textbook outcomes in those undergoing bladder (50.7% vs 44.0%; p = 0.001), kidney (72.0% vs 69.7%; p = 0.02), and prostate (85.3% vs 81.0%; p < 0.001) surgery. This effect was attenuated, but not eliminated, by surgical volume in additional sensitivity analyses for bladder (OR: 1.20, 95% CI: 1.00 -1.42; p = 0.04) and prostate (OR: 1.15, 95% CI: 1.00-1.32; p = 0.04) surgery. There were no significant differences in kidney cancer surgery outcomes after adjusting for hospital volume (OR: 1.03, 95% CI: 0.93 – 1.14; p = 0.6). ConclusionsUndergoing major cancer surgery at a teaching hospital was associated with an increased likelihood of receiving a textbook outcome. This effect was attenuated by volume but persisted for bladder and prostate surgery.

Value of Flemish Version of the Triage Risk Screening Tool in Predicting Unfavorable Outcomes after Elective Cancer Surgery: A Propensity Score-Matched Retrospective Cohort Study

Introduction: The Flemish version of the Triage Risk Screening Tool (fTRST), derived from the Triage Risk Screening Tool for assessing risk of readmission to the emergency department, is increasingly used as a simple screening tool in oncology. This study aimed to evaluate the utility of the fTRST in the context of elective surgical treatment for urologic cancer patients. Methods: We included 886 patients who underwent major urologic cancer surgery at our institution between 2020 and 2022 and underwent preoperative screening, including fTRST. We set the fTRST cutoff at 2 and used propensity score matching and multivariate regression analysis to assess how fTRST affected two postoperative outcomes: ambulation failure and delirium. Results: Of the 886 patients, 693 (78%) had an fTRST score <2, and 193 (22%) had an fTRST score ≥2 (high likelihood of frailty). After matching the groups by propensity scores, we compared the outcomes of 131 patients in each group. We found that the group with fTRST ≥2 had significantly higher rates of ambulation failure (15 vs. 11%, p = 0.03) and delirium (16 vs. 11%, p = 0.008) than the group with fTRST <2. Multivariate logistic regression analysis showed that fTRST score ≥2 was an independent risk factor for postoperative ambulation failure (odds ratio [OR] = 4.05, p = 0.02), along with age ≥75 years (OR = 6.62, p = 0.02), preoperative benzodiazepine medications (OR = 5.12, p = 0.01), and receiving radical cystectomy (OR = 9.30, p = 0.02). Similarly, for delirium, fTRST score ≥2 was an independent risk factor (OR = 2.88, p = 0.03), along with preoperative benzodiazepine medications (OR = 4.38, p = 0.002). Conclusion: The fTRST might be a screening tool with great potential for identifying patients at high risk for unfavorable postoperative outcomes in elective urologic cancer surgery.

Comparing Preoperative Screening Tools for Elective Urologic Cancer Surgery: Insights from a Cluster Analysis

Introduction: The aim of this study was to evaluate the features and benefits of different geriatric screening tools for enhancing the perioperative care of patients who undergo elective cancer surgery using cluster analysis. Methods: This study was a retrospective, observational analysis of 1,019 consecutive patients who had elective major cancer surgery in the urology department of our hospital from October 2019 to January 2023. Before the surgery, a trained nurse screened the patients using six tools: Eastern Clinical Oncology Group performance status (ECOG-PS), flemish version of the triage risk screening tool (fTRST), geriatric-8 (G8), instrumental activities of daily living, patient health questionnaire-2 (PHQ-2), and simple questionnaire to rapidly diagnose sarcopenia (SARC-F). The study grouped the patients into four clusters based on their scores on these tools and compared their outcomes after the surgery. The outcomes included overall survival, ambulation failure, delirium, and severe complications. The study also examined how each screening tool was associated with the outcomes. Results: Based on their clinical data and screening results, we classified the patients into four groups: Healthy (73%), Depressive (11%), Intermediate (11%), and Unhealthy (5%). The Unhealthy group had the worst outcomes in overall survival (OS), ambulation failure, and delirium, followed by the Intermediate group. In addition, fTRST and SARC-F emerged as significant predictors of OS; ECOG-PS, fTRST, G8, and SARC-F of ambulation failure; ECOG-PS, fTRST, and G8 of delirium; and G8 of severe complications. Conclusion: Various geriatric screening tools were found to have the potential to forecast diverse postoperative outcomes.

An exploratory study on the heterogeneity of postoperative delirium: Preoperative cognitive screening does not detect hallucinatory delirium risk

IntroductionThis study compared the clinical characteristics of patients who had hallucinations and those who did not during delirium after elective cancer surgery. Materials and methodsThis study retrospectively observed 1137 consecutive patients who had preoperative screening by a trained nurse before elective major urologic cancer surgery in our department. We compared the patient characteristics, including mini-cognitive assessment instrument (Mini-Cog) and Geriatric-8 (G8) scores, between those who developed postoperative delirium and those who did not, and also between those who had hallucinations and those who did not during delirium. ResultsOut of 1137 patients, 68 developed postoperative delirium, and 12 of them had hallucinations. A hierarchical cluster analysis based on the G8 and Mini-Cog scores divided the patients into two groups: one with high G8 and cognitive function (36 patients) and one with low G8 and cognitive function (32 patients). Hallucinations during delirium were more frequent in the high G8 and cognitive function group (11 out of 36 patients) than in the low G8 and cognitive function group (one out of 32 patients). Patients who had hallucinations during delirium also had higher preoperative Mini-Cog scores (P = 0.002) and G8 scores (P = 0.03) than those who did not, indicating better cognitive function and less frailty. DiscussionsWe identified a patient population that is prone to hallucinations that preoperative screening tools cannot detect. This suggests the heterogeneity of postoperative delirium and the need for further research.

Housework participation and mortality in Japanese male patients undergoing cancer surgery: A propensity score-matched study

BackgroundParticipation in housework and meal preparation are instrumental activity of daily living (IADL) evaluation items that is known to predict prognosis and complications in cancer care. However, these items are often assessed only for females, not for males, in IADL. MethodsWe examined the impact of habit of housework and meal preparation on overall survival (OS) in 1025 Japanese male patients who underwent elective urologic cancer surgery at our institution. The study also used a cohort that was matched by propensity score. ResultsWe found that patients who did not prepare meals or do housework had significantly shorter OS (hazard ratio [HR] = 3.34, P = 0.005; HR = 5.01, P < 0.001, respectively). Even in the cohort of 448 patients matched by propensity score and adjusted for age, body mass index, comorbidities, performance status, living status, cancer type, stage groups of cancer, and surgical approach, lack of participation in housework was associated with shorter OS (HR = 2.92, P = 0.04) and was an independent predictor of worse OS in multivariable analysis (HR = 5.13, P = 0.008). ConclusionsMales who did not regularly do household chores before elective cancer surgery had worse life outcomes. Doing more daily physical activities, such as household chores like making the bed and cleaning the room, might have a positive impact on survival when fighting cancer.

Cuproptosis: Mechanism, role, and advances in urological malignancies.

Prostate, bladder, and kidney cancers are the most common malignancies of the urinary system. Chemotherapeutic drugs are generally used as adjuvant treatment in the middle, late, or recurrence stages after surgery for urologic cancers. However, traditional chemotherapy is plagued by problems such as poor efficacy, severe side effects, and complications. Copper-containing nanomedicines are promising novel cancer treatment modalities that can potentially overcome these disadvantages. Copper homeostasis and cuproptosis play crucial roles in the development, adaptability, and therapeutic sensitivity of urological malignancies. Cuproptosis refers to the direct binding of copper ions to lipoylated components of the tricarboxylic acid cycle, leading to protein oligomerization, loss of iron-sulfur proteins, proteotoxic stress, and cell death. This review focuses on copper homeostasis and cuproptosis as well as recent findings on copper and cuproptosis in urological malignancies. Furthermore, we highlight the potential therapeutic applications of copper- and cuproptosis-targeted therapies to better understand cuproptosis-based drugs for the treatment of urological tumors in the future.

Molecular mechanisms underpinning favourable physiological adaptations to exercise prehabilitation for urological cancer surgery.

Surgery for urological cancers is associated with high complication rates and survivors commonly experience fatigue, reduced physical ability and quality of life. High-intensity interval training (HIIT) as surgical prehabilitation has been proven effective for improving the cardiorespiratory fitness (CRF) of urological cancer patients, however the mechanistic basis of this favourable adaptation is undefined. Thus, we aimed to assess the mechanisms of physiological responses to HIIT as surgical prehabilitation for urological cancer. Nineteen male patients scheduled for major urological surgery were randomised to complete 4-weeks HIIT prehabilitation (71.6 ± 0.75 years, BMI: 27.7 ± 0.9 kg·m2) or a no-intervention control (71.8 ± 1.1 years, BMI: 26.9 ± 1.3 kg·m2). Before and after the intervention period, patients underwent m. vastus lateralis biopsies to quantify the impact of HIIT on mitochondrial oxidative phosphorylation (OXPHOS) capacity, cumulative myofibrillar muscle protein synthesis (MPS) and anabolic, catabolic and insulin-related signalling. OXPHOS capacity increased with HIIT, with increased expression of electron transport chain protein complexes (C)-II (p = 0.010) and III (p = 0.045); and a significant correlation between changes in C-I (r = 0.80, p = 0.003), C-IV (r = 0.75, p = 0.008) and C-V (r = 0.61, p = 0.046) and changes in CRF. Neither MPS (1.81 ± 0.12 to 2.04 ± 0.14%·day-1, p = 0.39) nor anabolic or catabolic proteins were upregulated by HIIT (p > 0.05). There was, however, an increase in phosphorylation of AS160Thr642 (p = 0.046) post-HIIT. A HIIT surgical prehabilitation regime, which improved the CRF of urological cancer patients, enhanced capacity for skeletal muscle OXPHOS; offering potential mechanistic explanation for this favourable adaptation. HIIT did not stimulate MPS, synonymous with the observed lack of hypertrophy. Larger trials pairing patient-centred and clinical endpoints with mechanistic investigations are required to determine the broader impacts of HIIT prehabilitation in this cohort, and to inform on future optimisation (i.e., to increase muscle mass).

In-Hospital Venous Thromboembolism and Pulmonary Embolism After Major Urologic Cancer Surgery

BackgroundThis study aimed to test for temporal trends of in-hospital venous thromboembolism (VTE) and pulmonary embolism (PE) after major urologic cancer surgery (MUCS).MethodsIn the Nationwide Inpatient Sample (NIS) database (2010–2019), this study identified non-metastatic radical cystectomy (RC), radical prostatectomy (RP), radical nephrectomy (RN), and partial nephrectomy (PN) patients. Temporal trends of VTE and PE and multivariable logistic regression analyses (MLR) addressing VTE or PE, and mortality with VTE or PE were performed.ResultsOf 196,915 patients, 1180 (1.0%) exhibited VTE and 583 (0.3%) exhibited PE. The VTE rates increased from 0.6 to 0.7% (estimated annual percentage change [EAPC] + 4.0%; p = 0.01). Conversely, the PE rates decreased from 0.4 to 0.2% (EAPC − 4.5%; p = 0.01). No difference was observed in mortality with VTE (EAPC − 2.1%; p = 0.7) or with PE (EAPC − 1.2%; p = 0.8). In MLR relative to RP, RC (odds ratio [OR] 5.1), RN (OR 4.5), and PN (OR 3.6) were associated with higher VTE risk (all p < 0.001). Similarly in MLR relative to RP, RC (OR 4.6), RN (OR 3.3), and PN (OR 3.9) were associated with higher PE risk (all p < 0.001). In MLR, the risk of mortality was higher when VTE or PE was present in RC (VTE: OR 3.7, PE: OR 4.8; both p < 0.001) and RN (VTE: OR 5.2, PE: OR 8.3; both p < 0.001).ConclusionsRC, RN, and PN predisposes to a higher VTE and PE rates than RP. Moreover, among RC and RN patients with either VTE or PE, mortality is substantially higher than among their VTE or PE-free counterparts.

The significance of SARC-F scores in predicting postoperative outcomes of older adults undergoing elective major surgery for urologic cancer

Recently, the strength, assistance with walking, rise from a chair, climb stairs, and falls (SARC-F) questionnaire has been developed to screen patients with signs of sarcopenia. However, its clinical benefit remains uncertain in elderly patients undergoing elective major surgeries. This study aimed to explore the role of the SARC-F questionnaire as a screening tool for patients who plan to undergo elective major surgery for urologic cancer and to also evaluate correlations of SARC-F scores with established indicators of sarcopenia. This retrospective observational study enrolled 815 patients over 40 years of age undergoing elective major surgery for urologic cancer and who were screened with the SARC-F questionnaire, preoperatively. The primary endpoint was an association between SARC-F scores and postoperative ambulation failure. Here we define postoperative ambulation failure as a condition where a patient is unable to walk independently within 2 days after surgery and required physical rehabilitation or was transferred to other hospitals in a bedridden state. The secondary endpoint was an association between SARC-F scores and overall survival (OS). Psoas muscle density (PMD) and psoas muscle index (PMI) were calculated from abdominal computed tomography images, and their correlations with SARC-F scores grouped by sex. Of the 815 patients, 738 (91%) were male and the median age was 72 years. Although SARC-F scores weakly correlated with PMD in males and moderately correlated in females (ρ=-0.222 and ρ=-0.474, respectively), their correlation with PMI was negligible (ρ=-0.179 and ρ=-0.084, respectively). SARC-F scores successfully discriminate postoperative ambulation failure in both males and females with the respective area under the receiver operating characteristic curve of 0.856 and 0.813. Multivariate analysis also showed that SARC-F scores greater than 4 are an independent risk factor of postoperative ambulation failure along with older age, lower PMD, and poor performance status. SARC-F scores greater than 4 were significantly associated with a shorter OS in the whole cohort (P<0.001) and a subgroup of patients undergoing radical cystectomy (P=0.03; median follow-up of 515 days). The SARC-F questionnaire might be applicable to identify elderly patients at a higher risk of unfavourable outcomes after major urologic cancer surgery. A randomised controlled trial is necessary to confirm this finding.

Surgical care and outcomes in older patients with cancer through implementation of a pre-surgical toolkit (OPTI-Surg): Interim results of a phase III cluster randomized trial (Alliance A231601CD).

1541 Background: Frailty is common in older adults undergoing major cancer surgery. Mounting evidence indicates multimodal interventions to optimize patient functional status by addressing vulnerabilities associated with frailty before surgery result in decreased complications and enhanced functional recovery. This study tested the effectiveness of OPTI-Surg, a surgical prehabilitation toolkit for improving surgical care and outcomes in older patients undergoing major cancer surgery. Here, we report results from the planned futility interim analysis (IA). Methods: Thoracic (T), gastrointestinal (GI), and urologic (GU) oncological surgery practices affiliated with NCI’s Community Oncology Research Program were randomized 1:1:1, stratified by practice type, to usual care (control), OPTI-Surg toolkit, or OPTI-Surg with an implementation coach. The toolkit was implemented at the practice level. It consisted of the 12-item Edmonton Frail Scale and guided recommendations for interventions directed at identified vulnerabilities. Eligible patients were adults ≥70 years old undergoing curative intent surgery for lung, gastrointestinal, or urologic cancers. Primary outcome was 8-week post-operative function (weekly caloric expenditure) derived from the validated Community Healthy Activities Model Program for Seniors (CHAMPS) questionnaire. A linear mixed model was used to compare usual care to the 2 OPTI-Surg arms combined, controlling for baseline function. Results: From July 2019 to October 2021, 225 patients, 50% of the total accrual goal, were enrolled from 29 practices, triggering the IA. Study was suspended to new patient accrual March to June 2020 due to the COVID-19 pandemic. There were no differences in demographics by arm (mean age 76.2 years; 46.4% women; 79.6% white; 20.4% lung resection, 69.8% major GI surgery, 9.8% total cystectomy). Of the 225 patients, 140 (47 Usual Care, 93 OPTI-Surg) were evaluable for the IA. There was no significant difference in post-operative function between OPTI-Surg and usual care (mean decrease of 0.59 kCal/week for OPTI-Surg patients and 0.19 kCal/week for usual care patients, p = 0.762, intraclass correlation = 0.033). Based on the futility analysis, the DSMB recommended closure of recruitment on September 16, 2022. Conclusions: Implementation of the OPTI-Surg toolkit did not significantly improve functional outcomes 8 weeks after surgery for patients aged 70 and older undergoing major cancer surgery compared to usual care. Future analysis of implementation and ethnographic data may identify reasons why significant differences between the intervention and usual care arms were not observed, potentially including disruptions due to the COVID-19 pandemic.

Changes in Urologic Cancer Surgical Volume and Length of Stay During the COVID-19 Pandemic in Pennsylvania

Disruptions in cancer surgery during the COVID-19 pandemic led to widespread deferrals and cancellations, creating a surgical backlog that presents a challenge for health care institutions moving into the recovery phase of the pandemic. To describe patterns in surgical volume and postoperative length of stay for major urologic cancer surgery during the COVID-19 pandemic. This cohort study identified 24 001 patients 18 years or older from the Pennsylvania Health Care Cost Containment Council database with kidney cancer, prostate cancer, or bladder cancer who received a radical nephrectomy, partial nephrectomy, radical prostatectomy, or radical cystectomy between the first quarter (Q1) of 2016 and Q2 of 2021. Postoperative length of stay and adjusted surgical volumes were compared before and during the COVID-19 pandemic. The primary outcome was adjusted surgical volume for radical and partial nephrectomy, radical prostatectomy, and radical cystectomy during the COVID-19 pandemic. The secondary outcome was postoperative length of stay. A total of 24 001 patients (mean [SD] age, 63.1 [9.4] years; 3522 women [15%], 19 845 White patients [83%], 17 896 living in urban areas [75%]) received major urologic cancer surgery between Q1 of 2016 and Q2 of 2021. Of these, 4896 radical nephrectomy, 3508 partial nephrectomy, 13 327 radical prostatectomy, and 2270 radical cystectomy surgical procedures were performed. There were no statistically significant differences in patient age, sex, race, ethnicity, insurance status, urban or rural status, or Elixhauser Comorbidity Index scores between patients who received surgery before and patients who received surgery during the pandemic. For partial nephrectomy, a baseline of 168 surgeries per quarter decreased to 137 surgeries per quarter in Q2 and Q3 of 2020. For radical prostatectomy, a baseline of 644 surgeries per quarter decreased to 527 surgeries per quarter in Q2 and Q3 of 2020. However, the likelihood of receiving radical nephrectomy (odds ratio [OR], 1.00; 95% CI, 0.78-1.28), partial nephrectomy (OR, 0.99; 95% CI, 0.77-1.27), radical prostatectomy (OR, 0.85; 95% CI, 0.22-3.22), or radical cystectomy (OR, 0.69; 95% CI, 0.31-1.53) was unchanged. Length of stay for partial nephrectomy decreased from baseline by a mean of 0.7 days (95% CI, -1.2 to -0.2 days) during the pandemic. This cohort study suggests that partial nephrectomy and radical prostatectomy surgical volume decreased during the peak waves of COVID-19, as did postoperative length of stay for partial nephrectomy.

The test-retest reproducibility of the multiple array probe Leiden in men with lower urinary tract symptoms.

We aimed to study the test-retest reliability of the Multiple Array Probe Leiden (MAPLe), a multiple electrode probe designed to acquire and discriminate electromyography signals in the pelvic floor muscles, in men with lower urinary tract symptoms (LUTS). Adult male patients with LUTS with sufficient knowledge of Dutch language, but without complications (e.g., urinary tract infection), or previous urologic cancer and/or urologic surgery were enrolled. In the initial study, next to physical examination and uroflowmetry, all men underwent MAPLe assessment at baseline and after 6 weeks. Second, participants were reinvited for a new assessment using a stricter protocol. A time interval of 2 h (M2) and 1 week (M3) after baseline (M1) allowed the calculation of the intraday agreement (M1 vs. M2), and the interday agreement (M1 vs. M3) for all 13 MAPLe variables. The outcomes of the initial study in 21 men suggested a poor test-retest reliability. The second study in 23 men showed a good test-retest reliability with intraclass correlations ranging from 0.61 (0.12-0.86) to 0.91 (0.81-0.96). The agreement was generally higher for the intraday determinations than for the interday determinations. This study revealed a good test-retest reliability of the MAPLe device in men with LUTS, when using a strict protocol. With a less strict protocol, the test-retest reliability of MAPLe was poor in this sample. To make valid interpretations of this device in a clinical or research setting, a strict protocol is needed.

Integrative review of remote patient monitoring in gynecologic and urologic surgical oncology.

Patients with cancer facing complex and invasive urologic and gynecologic cancer surgery often experience symptoms and rapid declines in functional capacity postoperatively. Remote patient monitoring that leverages patient-generated health datais a potential approach to assess and promote postoperative recovery. This integrative review aims to provide an overview of the current literature and research on remote patient monitoring in gynecologic and urologic surgical oncology.
