The number of treatment options for patients with metastatic renal cell carcinoma (mRCC) has significantly grown in the last 15 years. Although randomized controlled trials are fundamental in investigating mRCC treatment efficacy, their external validity can be limited. Therefore, the efficacy of the different treatment options should also be evaluated in clinical practice. We performed a chart review of electronic health records using text mining software to study the current treatment patterns and outcomes. mRCC patients from two large hospitals in the Netherlands, starting treatment between January 2015 and May 2020, were included. Data were collected from electronic health records using a validated text mining tool. Primary endpoints were progression-free survival (PFS) and overall survival (OS). Statistical analyses were performed using the Kaplan–Meier method. Most frequent first-line treatments were pazopanib (n = 70), sunitinib (n = 34), and nivolumab with ipilimumab (n = 28). The overall median PFS values for first-line treatment were 15.7 months (95% confidence interval [95%CI], 8.8–20.7), 16.3 months (95%CI, 9.3–not estimable [NE]) for pazopanib, and 6.9 months (95% CI, 4.4–NE) for sunitinib. The overall median OS values were 33.4 months (95%CI, 28.1–50.9 months), 39.3 months (95%CI, 29.5–NE) for pazopanib, and 28.1 months (95%CI, 7.0–NE) for sunitinib. For nivolumab with ipilimumab, median PFS and median OS were not reached. Of the patients who finished first- and second-line treatments, 64 and 62% received follow-up treatments, respectively. With most patients starting on pazopanib and sunitinib, these real-world treatment outcomes were most likely better than in pivotal trials, which may be due to extensive follow-up treatments.

BACKGROUND Pulmonary embolism is one of the leading causes of maternal death in the Western world. Because of the low specificity and sensitivity of the D-dimer test, all pregnant women with suspected pulmonary embolism undergo computed tomographic (CT) pulmonary angiography or ventilation-perfusion scanning, both of which involve radiation exposure to the mother and fetus. Whether a pregnancy-adapted algorithm could be used to safely avoid diagnostic imaging in pregnant women with suspected pulmonary embolism is unknown. METHODS In a prospective study involving pregnant women with suspected pulmonary embolism, we assessed three criteria from the YEARS algorithm (clinical signs of deep-vein thrombosis, hemoptysis, and pulmonary embolism as the most likely diagnosis) and measured the D-dimer level. Pulmonary embolism was ruled out if none of the three criteria were met and the D-dimer level was less than 1000 ng per milliliter or if one or more of the three criteria were met and the D-dimer level was less than 500 ng per milliliter. Adaptation of the YEARS algorithm for pregnant women involved compression ultrasonography for women with symptoms of deep-vein thrombosis; if the results were positive (i.e., a clot was present), CT pulmonary angiography was not performed. All patients in whom pulmonary embolism had not been ruled out underwent CT pulmonary angiography. The primary outcome was the incidence of venous thromboembolism at 3 months. The secondary outcome was the proportion of patients in whom CT pulmonary angiography was not indicated to safely rule out pulmonary embolism. RESULTS A total of 510 women were screened, of whom 12 (2.4%) were excluded. Pulmonary embolism was diagnosed in 20 patients (4.0%) at baseline. During follow-up, popliteal deep-vein thrombosis was diagnosed in 1 patient (0.21%; 95% confidence interval [Cl], 0.04 to 1.2); no patient had pulmonary embolism. CT pulmonary angiography was not indicated, and thus was avoided, in 195 patients (39%; 95% Cl, 35 to 44). The efficiency of the algorithm was highest during the first trimester of pregnancy and lowest during the third trimester; CT pulmonary angiography was avoided in 65% of patients who began the study in the first trimester and in 32% who began the study in the third trimester. CONCLUSIONS Pulmonary embolism was safely ruled out by the pregnancy-adapted YEARS diagnostic algorithm across all trimesters of pregnancy. CT pulmonary angiography was avoided in 32 to 65% of patients. (Funded by Leiden University Medical Center and 17 other participating hospitals; Artemis Netherlands Trial Register number, NL5726.)

Background and Aims: Coexisting atrial fibrillation (AF) and cancer challenge the management of both. The aim of the study is to comprehensively provide the epidemiology of coexisting AF and cancer., Methods: Using Dutch nationwide statistics, individuals with incident AF (n = 320 139) or cancer (n = 472 745) were identified during the period 2015-19. Dutch inhabitants without a history of AF (n = 320 135) or cancer (n = 472 741) were matched as control cohorts by demographic characteristics. Prevalence of cancer/AF at baseline, 1-year risk of cancer/AF diagnosis, and their time trends were determined. The association of cancer/AF diagnosis with all-cause mortality among those with AF/cancer was estimated by using time-dependent Cox regression., Results: The rate of prevalence of cancer in the AF cohort was 12.6% (increasing from 11.9% to 13.2%) compared with 5.6% in the controls; 1-year cancer risk was 2.5% (stable over years) compared with 1.8% in the controls [adjusted hazard ratio (aHR) 1.52, 95% confidence interval (CI) 1.46-1.58], which was similar by cancer type. The rate of prevalence of AF in the cancer cohort was 7.5% (increasing from 6.9% to 8.2%) compared with 4.3% in the controls; 1-year AF risk was 2.8% (stable over years) compared with 1.2% in the controls (aHR 2.78, 95% CI 2.69-2.87), but cancers of the oesophagus, lung, stomach, myeloma, and lymphoma were associated with higher hazards of AF than other cancer types. Both cancer diagnosed after incident AF (aHR 7.77, 95% CI 7.45-8.11) and AF diagnosed after incident cancer (aHR 2.55, 95% CI 2.47-2.63) were associated with all-cause mortality, but the strength of the association varied by cancer type., Conclusions: Atrial fibrillation and cancer were associated bidirectionally and were increasingly coexisting, but AF risk varied by cancer type. Coexisting AF and cancer were negatively associated with survival., (© The Author(s) 2024. Published by Oxford University Press on behalf of the European Society of Cardiology.)

Purpose: The aim of this study was to investigate the biodistribution of (super-)selective trans-arterial radioembolization (TARE) with holmium-166 microspheres ( 166 Ho-MS), when administered as adjuvant therapy after RFA of HCC 2-5 cm. The objective was to establish a treatment volume absorbed dose that results in an absorbed dose of ≥ 120 Gy on the hyperemic zone around the ablation necrosis (i.e., target volume)., Methods: In this multicenter, prospective dose-escalation study in BCLC early stage HCC patients with lesions 2-5 cm, RFA was followed by (super-)selective infusion of 166 Ho-MS on day 5-10 after RFA. Dose distribution within the treatment volume was based on SPECT-CT. Cohorts of up to 10 patients were treated with an incremental dose (60 Gy, 90 Gy, 120 Gy) of 166 Ho-MS to the treatment volume. The primary endpoint was to obtain a target volume dose of ≥ 120 Gy in 9/10 patients within a cohort., Results: Twelve patients were treated (male 10; median age, 66.5 years (IQR, [64.3-71.7])) with a median tumor diameter of 2.7 cm (IQR, [2.1-4.0]). At a treatment volume absorbed dose of 90 Gy, the primary endpoint was met with a median absorbed target volume dose of 138 Gy (IQR, [127-145]). No local recurrences were found within 1-year follow-up., Conclusion: Adjuvant (super-)selective infusion of 166 Ho-MS after RFA for the treatment of HCC can be administered safely at a dose of 90 Gy to the treatment volume while reaching a dose of ≥ 120 Gy to the target volume and may be a favorable adjuvant therapy for HCC lesions 2-5 cm., Trial Registration: Clinicaltrials.gov NCT03437382 .

Introduction: Cabozantinib is one of the preferred treatment options in the latest metastatic renal cell carcinoma (mRCC) guidelines. Cabozantinib is also associated with high drug expenses irrespective of the used dose, because a flat-prizing model has been implemented. In addition, concomitant intake with a high-fat meal increases its bioavailability on average by 57%. Combined with the long terminal half-life of cabozantinib (99 h), this creates possibilities to extend the dosing interval to reduce drug expenses whilst maintaining equivalent exposure., Objectives: The primary objective was to evaluate the population pharmacokinetic (POPPK) model of cabozantinib developed for its registration using real-world patients' therapeutic drug monitoring (TDM) data. The secondary objective was to design, simulate, and evaluate alternative dose regimens with the aim to reduce drug expenses whilst maintaining comparable exposure., Methods: Retrospective TDM data from mRCC patients treated with cabozantinib were obtained. The data were evaluated using the published Food and Drug Administration (FDA) cabozantinib POPPK model, a two-compartment disposition model with a dual (fast and slow) lagged first-order absorption process derived from FDA registration documents, as a basis. Subsequently, simulations of alternative drug expenses saving regimens were evaluated., Results: Twenty-seven mRCC patients with 75 pharmacokinetic observations were included. Patients were treated for a median of 75 days with a median dose of 40 mg. Model evaluation results showed that the cabozantinib TDM concentrations were adequately predicted by the published FDA cabozantinib POPPK model, except for a slightly higher clearance (CL) of 3.11 L/h compared to the reported value (2.23 L/h). The simulation study indicated that an alternative dose regimen that consists of taking 60 mg of cabozantinib for 2 days and then skipping 1 day results in comparable average exposure when compared with a 40 mg daily dose, both without food interaction, while saving 33.3% of the total drug expenses per month. The food effect of a high-fat meal was also taken into account when simulating other alternative dose regimens; 40 mg every 72 h combined with a high-fat meal resulted in comparable exposure when compared with a 20 mg daily dose fasted, while saving 66.7% in drug expenses., Conclusions: In this study, the optimized cabozantinib POPPK model resulted in adequate prediction of real-world cabozantinib pharmacokinetic data. Alternative dosing regimens with and without using known food interactions were proposed that resulted in potential strategies to significantly reduce cabozantinib drug expenses., (© 2024.

Background: With 5-year survival rates > 85%, gaining insight into the long-term and late health-related conditions of cancer survivors diagnosed in adolescence and young adulthood is of utmost importance to improve their quantity and quality of survival. This study examined the prevalence of and factors associated with, patient-reported health-related conditions and their latency times among long-term adolescent and young adult (AYA) cancer survivors., Methods: AYA cancer survivors (5-20 years after diagnosis) were identified by the population-based Netherlands Cancer Registry (NCR), and invited to participate in the SURVAYA questionnaire study. Participants reported the prevalence and date of diagnosis of health-related conditions. Clinical data were retrieved from the NCR., Results: Three thousand seven hundred seventy-six AYA cancer survivors (response rate 33.4%) were included for analyses. More than half of the AYAs (58.5%) experienced health-related conditions after their cancer diagnosis, of whom 51.4% were diagnosed with two or more conditions. Participants reported conditions related to vision (15.0%), digestive system (15.0%), endocrine system (14.1%), cardiovascular system (11.7%), respiratory system (11.3%), urinary tract system (10.9%), depression (8.6%), hearing (7.4%), arthrosis (6.9%), secondary malignancy (6.4%), speech-, taste and smell (4.5%), and rheumatoid arthritis (2.1%). Time since diagnosis, tumor type, age at diagnosis, and educational level were most frequently associated with a health-related condition., Conclusions: A significant proportion of long-term AYA cancer survivors report having one or more health-related conditions., Implications for Cancer Survivors: Future research should focus on better understanding the underlying mechanisms of, and risk factors for, these health-related conditions to support the development and implementation of risk-stratified survivorship care for AYA cancer survivors to further improve their outcomes., Clinical Trials Registration: NCT05379387., (© 2024.

Background: Adolescent and young adult cancer survivors (AYAs, aged 18-39 years at first diagnosis) have a higher second cancer risk. Accelerated aging is hypothesized as underlying mechanism and has been described clinically by 6 indicators; fatigue, low quality of sleep, low mood, lack of motivation, subjective memory complaints, and poor exercise tolerance. Using patient-reported outcomes, we aimed to identify clusters of accelerated aging among AYA cancer survivors and to investigate their association with second cancer development., Patients and Methods: Patient, tumor, and treatment data were obtained from the Netherlands Cancer Registry. Patient-reported clinical indicators and second cancer data were obtained from the SURVivors (5-20 years) of cancer in AYAs (SURVAYA) questionnaire study between 1999 and 2015. Latent class and multivariable logistic regression analyses were performed., Results: In total, n = 3734 AYA survivors with known second cancer status (n = 278 [7.4%] second cancers) were included. Four latent clusters were identified and named based on their clinical indicator features; (1) high accelerated aging (31.3%), (2) intermediate accelerated aging without poor exercise tolerance (15.1%), (3) intermediate accelerated aging without lack of motivation (27.4%), and (4) low accelerated aging (26.2%). AYAs in the high accelerated aging cluster were more likely to have second cancer (odds ratio: 1.6; 95% CI, 1.1-2.3) compared to the low accelerated aging cluster., Conclusion: AYAs with a higher burden of accelerated aging were more likely to develop a second cancer. Validation of the clinical indicators and how to best capture them is needed to improve (early) detection of AYAs at high risk of developing second cancer., (© The Author(s) 2023.

Purpose: To describe recall of fertility-related consultations and cryopreservation and to examine reproductive goals and reproduction post-treatment in long-term survivors of adolescent and young adult (AYA) (age, 18-39 years) cancer., Methods: This study included n = 1457 male and n = 2112 female long-term survivors (M age  = 43-45 years; 5-22 years from diagnosis) who provided self-report. Clinical data were supplied by the Netherlands Cancer Registry., Results: Most male survivors (72.7%) recalled fertility-related consultations and 22.6% completed sperm cryopreservation. Younger age (OR = 2.8; 95%CI [2.2-3.6]), not having children (OR = 5.0; 95%CI [3.2-7.7]), testicular cancer or lymphoma/leukemia (OR = 2.8/2.5 relative to "others"), and more intense treatments (OR = 1.5; 95%CI [1.1-2.0]) were associated with higher cryopreservation rates. Time since diagnosis had no effect. Of men who cryopreserved, 12.1% utilized assisted reproductive technologies (ART). Most men (88.5%) felt their diagnosis did not affect their reproductive goals, but 7.6% wanted no (additional) children due to cancer. Half of female survivors (55.4%; n = 1171) recalled fertility-related consultations. Rates of cryopreservation were very low (3.6%), but increased after 2013 when oocyte cryopreservation became non-experimental. Of women who cryopreserved, 13.2% successfully utilized ART. Most women (74.8%) experienced no effects of cancer on reproductive goals, but 17.8% wanted no (additional) children due to cancer., Conclusions: Cryopreservation in men varied by patient/clinical factors and was very low in women, but data of more recently treated females are needed. Utilizing cryopreserved material through ART was rare, which questions its cost-effectiveness, but it may enhance survivors' well-being., Implications for Cancer Survivors: The extent to which cryopreservation positively affects survivors' well-being remains to be tested. Moreover, effects of cancer on reproductive goals require further attention, especially in women who refrain from having children due to cancer., (© 2024. The Author(s).)

Purpose: For adolescent and young adult (AYA) cancer survivors with a good prognosis, having a healthy lifestyle prevents morbidity and mortality after treatment. The aim of this study was to investigate the prevalence of (un)healthy lifestyle behaviors and related determinants in AYA cancer survivors., Methods: A population-based, cross-sectional study was performed among long-term (5-20 years) AYA cancer survivors (18-39 years old at diagnosis) registered within the Netherlands Cancer Registry. Self-reported questionnaires data about health behaviors were used to calculate the 2018 World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) adherence score. Associations between the score and clinical/sociodemographic determinants of (un)healthy behaviors were investigated using logistic regression models., Results: The mean WCRF/AICR score was low to moderate, 3.8 ± 1.2 (0.5-7.0) (n = 3668). Sixty-one percent adhered to "limit the consumption of sugar sweetened drinks," 28% to "be a healthy weight," 25% to "fruit and vegetable consumption," and 31% to "limit alcohol consumption." Moderate and high adherence were associated with being a woman (OR moderate  = 1.46, 95% CI = 1.14-1.85, and OR high  = 1.87, 95% CI = 1.46-2.4) and highly educated (OR moderate  = 1.54, 95% CI = 1.30-1.83, and OR high  = 1.87, 95% CI = 1.46-2.4). Low adherence was associated with smoking (OR moderate  = 0.68, 95% CI = 0.50-0.92, and OR high  = 0.30, 95% CI = 0.21-0.44) and diagnosis of germ cell tumor (OR moderate  = 0.58, 95% CI = 0.39-0.86, and OR high  = 0.45, 95% CI = 0.30-0.69)., Conclusions: Adherence to the 2018 WCRF/AICR lifestyle recommendations was low to moderate, especially regarding body weight, fruit, vegetables, and alcohol consumption. Men, current smokers, lower-educated participants, and/or those diagnosed with germ cell tumors were less likely to have a healthy lifestyle., Implications for Cancer Survivors: Health-promotion programs (e.g., age-specific tools) are needed, focusing on high-risk groups., (© 2024.

Purpose: Adolescent and young adult cancer survivors (AYAs) are at increased risk of long-term and late effects, and experience unmet needs, impacting their health-related quality of life (HRQoL). In order to provide and optimize supportive care and targeted interventions for this unique population, it is important to study HRQoL factors' interconnectedness on a population level. Therefore, this network analysis was performed with the aim to explore the interconnectedness between HRQoL factors, in the analysis described as nodes, among long-term AYAs., Methods: This population-based cohort study used cross-sectional survey data of long-term AYAs, who were identified by the Netherlands Cancer Registry (NCR). Participants completed a one-time survey (SURVAYA study), including the EORTC survivorship questionnaire (QLQ-SURV111) to assess their long-term HRQoL outcomes and sociodemographic characteristics. The NCR provided the clinical data. Descriptive statistics and a network analysis, including network clustering, were performed., Results: In total, 3596 AYAs (on average 12.4 years post diagnosis) were included in our network analysis. The network was proven stable and reliable and, in total, four clusters were identified, including a worriment, daily functioning, psychological, and sexual cluster. Negative health outlook, part of the worriment cluster, was the node with the highest strength and its partial correlation with health distress was significantly different from all other partial correlations., Conclusion: This study shows the results of a stable and reliable network analysis based on HRQoL data of long-term AYAs, and identified nodes, correlations, and clusters that could be intervened on to improve the HRQoL outcomes of AYAs., (© 2024.

Background: The recently published 4-level Pulmonary Embolism Clinical Probability Score (4PEPS) integrates different aspects from currently available diagnostic strategies to further reduce imaging testing in patients with clinically suspected pulmonary embolism (PE)., Aim: To externally validate the performance of 4PEPS in an independent cohort., Methods: In this post-hoc analysis of the prospective diagnostic management YEARS study, the primary outcome measures were discrimination, calibration, efficiency (proportion of imaging tests potentially avoided), and failure rate (venous thromboembolism (VTE) diagnosis at baseline or follow-up in patients with a negative 4PEPS algorithm). Multiple imputation was used for missing 4PEPS items. Based on 4PEPS, PE was considered ruled out in patients with a very low clinical pre-test probability (CPTP) without D-dimer testing, in patients with a low CPTP and D-dimer <1000 μg/L, and in patients with a moderate CPP and D-dimer below the age-adjusted threshold., Results: Of the 3465 patients, 474 (14 %) were diagnosed with VTE at baseline or during 3-month follow-up. Discriminatory performance of the 4PEPS items was good (area under ROC-curve, 0.82; 95%CI, 0.80-0.84) as was calibration. Based on 4PEPS, PE could be considered ruled out without imaging in 58 % (95%CI 57-60) of patients (efficiency), for an overall failure rate of 1.3 % (95%CI 0.86-1.9)., Conclusion: In this retrospective external validation, 4PEPS appeared to safely rule out PE with a high efficiency. Nevertheless, although not exceeding the failure rate margin by ISTH standards, the observed failure rate in our analysis appeared to be higher than in the original 4PEPS derivation and validation study. This highlights the importance of a prospective outcome study., Competing Interests: Declaration of competing interest MJHA Kruip received research support from Sobi, The Netherlands Organisation for Health Research and Development and The Dutch Thrombosis Association for research outside this study and speakers fee from BMS, Roche and Sobi, payment to institution.

Background and Aims: Cancer provides challenges to the continuity of anticoagulant treatment in patients with atrial fibrillation (AF), e.g. through cancer-related surgery or complications. We aimed to provide data on the incidence and reasons for interrupting and discontinuing anticoagulant treatment in AF patients with cancer and to assess its contribution to the risk of thromboembolism (TE) and major bleeding (MB)., Methods: This retrospective study identified AF patients with cancer in two hospitals between 2012 and 2017. Data on anticoagulant treatment, TE and MB were collected during two-year follow-up. Incidence rates (IR) per 100 patient-years and adjusted hazard ratios (aHR) were obtained for TE and MB occurring during on- and off-anticoagulant treatment, during interruption and after resumption, and after permanent discontinuation., Results: 1213 AF patients with cancer were identified, of which 140 patients permanently discontinued anticoagulants and 426 patients experienced one or more interruptions. Anticoagulation was most often interrupted or discontinued due to cancer-related treatment (n = 441, 62 %), bleeding (n = 129, 18 %) or end of life (n = 36, 5 %). The risk of TE was highest off-anticoagulation and during interruptions, with IRs of 19 (14-25)) and 105 (64-13), and aHRs of 3.1 (1.9-5.0) and 4.6 (2.4-9.0), respectively. Major bleeding risk were not only increased during an interruption, but also in the first 30 days after resumption, with IRs of 33 (12-72) and 30 (17-48), and aHRs of 3.3 (1.1-9.8) and 2.4 (1.2-4.6), respectively., Conclusions: Interruption of anticoagulation therapy harbors high TE and MB risk in AF patients with cancer. The high incidence rates call for better (periprocedural) anticoagulant management strategies tailored to the cancer setting., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Authors.
