Show morePurposeTo 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.MethodsThis study included n = 1457 male and n = 2112 female long-term survivors (Mage = 43-45 years; 5-22 years from diagnosis) who provided self-report. Clinical data were supplied by the Netherlands Cancer Registry.ResultsMost 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.ConclusionsCryopreservation 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 SurvivorsThe 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. Show less

Show moreAlthough anti-cancer treatments have significantly advanced over the past decades, obstacles to accomplishing successful treatment still exist. The occurrence of treatment resistance is one of the major factors that limit the long-lasting efficacy of anti-cancer treatment. Additionally, substantial variability in pharmacokinetics (PK) / pharmacodynamics (PD) of anti-cancer drugs also challenges successful oncology treatment. Therefore, gaining knowledge of and ultimately better suppressing evolutionary resistance development during treatment, and applying personalized treatment are desired to improve anti-cancer treatment. In this thesis, we have applied quantitative modeling approaches to address these needs, aiming for improved treatment for oncology patients. Our work demonstrated that with the quantitative models, the evolutionary progression of tumors could be characterized and predicted, accounting for interactions among heterogeneous tumor cells and supported by mutant gene variants detected in circulating tumor DNA (ctDNA). In addition, we developed population PK /PD models which enabled quantitative description of the PK and PD of anti-cancer drugs and corresponding variabilities in real-world patients. The developed models have been further applied to support the identification of optimal treatment strategies and guide individualized treatment for oncology patients. Show less

Show moreCancers accounts for approximately one-in-six deaths worldwide. Despite the advances in treatment options over the past couple decades surgery remains the cornerstone for almost all solid tumors. Radical excision is crucial for curative treatment, however, intraoperative tumor identification is hampered by (1) fibrosis, inflammation and necrosis due to neoadjuvant therapy, and (2) an altered surgical field due to the adoption of laparoscopic and robotic procedures. In response, fluorescence guided surgery (FGS) has been introduced to the operating theater. FGS utilizes near-infrared light to visualize, an often intravenously administered, tumor-targeting tracer in real-time. In this thesis, uPAR was studied as target for FGS and uPAR-targeting FGS tracers were developed and compared in various cancer models. Show less

Show moreIn this thesis, different preclinical strategies were explored aiming at the identification of putative novel therapies for prostate and bladder cancer. The first part of this thesis (Chapter 2 and Chapter 3) describes the generationof preclinical, patient-derived model systems of prostate and bladder cancer. In Chapter 2, an overview is provided of the most commonly used patient-derived model systems for urological tumors, and a framework on how these patient derived tumor models can be employed to address preclinical and clinical unmet needs is presented. In Chapter 3, we developed and optimized the culture of ex vivo tumor tissue slices and employed this model to detect anti-tumor responses of chemotherapeutic agents Docetaxel and Gemicitabin. Subsequently in Chapters 4, 5 and 6, we describe the use of multiple preclinical translational models, including patient-derived tumor models. In Chapter 4 and 5 the translational potential of the approved antipsychotic drug penfluridol was determined in bladder and prostate cancer. In Chapter 6, the use of oncolytic reovirus jin-3 as putative novel therapeutic strategy for the treatment of prostate is investigated. Finally, in Chapter 7, we describe a novel preclinical screening strategy based on E-cadherin (re)induction and inhibition of invasion for the identification of a new class of small molecules for the treatment of aggressive epithelial cancers.

Show morePurposeThe present study aimed to determine the prevalence of self-reported oral problems and the oral health-related quality of life (OHRQoL) in childhood cancer survivors (CCS).MethodsPatient and treatment characteristics of CCS have been collected in a cross-sectional study, part of the multidisciplinary DCCSS-LATER 2 Study. To assess self-reported oral health problems and dental problems, CCS filled out the 'Toegepast-Natuurwetenschappelijk Onderzoek' (TNO) oral health questionnaire. OHRQoL was assessed by the Dutch version of the Oral Health Impact Profile-14 (OHIP-14). Prevalences were compared with two comparison groups from the literature. Univariable and multivariable analyses were performed.ResultsA total of 249 CCS participated in our study. The OHIP-14 total score had a mean value of 1.94 (sd 4.39), with a median score of 0 (range 0-29). The oral problems 'oral blisters/aphthae' (25.9%) and 'bad odor/halitosis' (23.3%) were significantly more often reported in CCS than in comparison groups (12% and 12%, respectively). The OHIP-14 score was significantly correlated with the number of self-reported oral health problems (r = .333, p<0.0005) and dental problems (r = .392, p <0.0005). In multivariable analysis, CCS with a shorter time since diagnosis (10-19 years vs. >= 30 years) had a 1.47-fold higher risk of >= 1 oral health problem.ConclusionThough the perceived oral health is relatively good, oral complications following childhood cancer treatment are prevalent in CCS. This underlines that attention to impaired oral health and awareness on this topic is mandatory and regular visits to the dentist should be a part of long-term follow-up care. Show less

Show moreTranscriptome signature reversion (TSR) has been extensively proposed and used to discover new indications for existing drugs (i.e. drug repositioning, drug repurposing) for various cancer types. TSR relies on the assumption that a drug that can revert gene expression changes induced by a disease back to original, i.e. healthy, levels is likely to be therapeutically active in treating the disease. Here, we aimed to validate the concept of TSR using the PRISM repurposing data set, which is-as of writing-the largest pharmacogenomic data set. The predictive utility of the TSR approach as it has currently been used appears to be much lower than previously reported and is completely nullified after the drug gene expression signatures are adjusted for the general anti-proliferative downstream effects of drug-induced decreased cell viability. Therefore, TSR mainly relies on generic anti-proliferative drug effects rather than on targeting cancer pathways specifically upregulated in tumor types. Show less

Show moreThis thesis aimed to find opportunities to improve proactivity and patient-centredness in palliative care, focussing on education and care outcomes. The 2009 national blueprint on medical education and the Dutch medical curricula did not comprise all essential elements about end-of-life care. Factors associated with approaching death in patients with advanced cancer visiting the LUMC’s Emergency Department (ED) in the last three months of life were lung cancer, neurologic deterioration, dyspnoea, hypercalcemia and jaundice. Patients with haematological malignancies received more potentially inappropriate care than advanced cancer patients. They rarely had limitations on life-sustaining treatments, although they often died of disease progression or treatment toxicity. The surprise question (SQ) is a simple tool to identify patients with palliative care needs . Adding poor performance status to the SQ improved the predictive value for one-year mortality in advanced cancer patients visiting the LUMC’s ED. The Leiden Guide on Palliative Care (LGP) was developed by the Centre of Expertise in Palliative Care to assess symptom burden and information needs. Patients and family wanted information about current problems and about their worries. Patients, family and clinicians found the LGP helpful. Using their input, the LGP was improved for use by generalist palliative care clinicians. Show less

Show moreIntroduction This guideline was written by a multidisciplinary committee with mandated members of the Dutch Society for Infectious Diseases, Dutch Society for Hematology, Dutch Society for Medical Oncology, Dutch Association of Hospital Pharmacists, Dutch Society for Medical Microbiology, and Dutch Society for Pediatrics. The guideline is written for adults and pediatric patients. Method The recommendations are based on the answers to nine questions formulated by the guideline committee. To provide evidence-based recommendations we used all relevant clinical guidelines published since 2010 as a source, supplemented with systematic searches and evaluation of the recent literature (2010-2020) and, where necessary, supplemented by expert-based advice. Results For adults the guideline distinguishes between high- and standard-risk neutropenia based on expected duration of neutropenia (> 7 days versus <= 7 days). Where possible a distinction has been made between pediatric and adult patients. Conclusion This guideline was written to aid diagnosis and management of patients with febrile neutropenia due to chemotherapy in the Netherlands. The guideline provides recommendation for children and adults. Adults patient are subdivided as having a standard- or high-risk neutropenic episode based on estimated duration of neutropenia. The most important recommendations are as follows. In adults with high-risk neutropenia (duration of neutropenia > 7 days) and in children with neutropenia, ceftazidime, cefepime, and piperacillin-tazobactam are all first-choice options for empirical antibiotic therapy in case of fever. In adults with standard-risk neutropenia (duration of neutropenia <= 7 days) the MASCC score can be used to assess the individual risk of infectious complications. For patients with a low risk of infectious complications (high MASCC score) oral antibiotic therapy in an outpatient setting is recommended. For patients with a high risk of infectious complications (low MASCC score) antibiotic therapy per protocol sepsis of unknown origin is recommended. Show less

Show moreIn this thesis, we aimed to develop and validate a patient and a physician questionnaire to measure the shared decision making (SDM) process in oncology. We identified SDM measurement challenges: there is limited evidence on measurement properties, patients’ role is not assessed while it is present in SDM models, patients and healthcare professionals have been involved only to a limited extent in the development of SDM measurement instruments, and a reflective measurement model is often assumed, while a formative might be more appropriate. The aim of this thesis was therefore to develop and validate questionnaires to assess the SDM process in oncology from both the patient and the physician viewpoints. We chose the oncology setting because it is a setting in which patients often face preference-sensitive decisions, and in which most patients prefer an active or collaborative role in treatment decision making. To inform the development and validation process of our questionnaires, we used the original Consensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist and we wrote two reviews: one on existing SDM measurement instruments and one on existing SDM models. The iSHARE questionnaires shows adequate measurement properties Show less

Show moreObjectives: We have developed two Dutch questionnaires to assess the shared decision-making (SDM) process in oncology; the iSHAREpatient and iSHAREphysician. In this study, we aimed to determine: scores, construct validity, test-retest agreement (iSHAREpatient), and inter-rater (iSHAREpatient-iSHAREphysician) agreement. Methods: Physicians from seven Dutch hospitals recruited cancer patients, and completed the iSHAREphysician and SDM-Questionnaire-physician version. Their patients completed the: iSHAREpatient, nine-item SDM-Questionnaire, Decisional Conflict Scale, Combined Outcome Measure for Risk communication And treatment Decision-making Effectiveness, and five-item Perceived Efficacy in Patient-Physician Interactions. We formulated, respectively, one (iSHAREphysician) and 10 (iSHAREpatient) a priori hypotheses regarding correlations between the iSHARE questionnaires and questionnaires assessing related constructs. To assess test-retest agreement patients completed the iSHAREpatient again 1-2 weeks later. Results: In total, 151 treatment decision-making processes with unique patients were rated. Dimension and total iSHARE scores were high both in patients and physicians. The hypothesis on the iSHAREphysician and 9/10 hypotheses on the iSHAREpatient were confirmed. Test-retest and inter-rater agreement were >.60 for most items. Conclusions: The iSHARE questionnaires show high scores, have good construct validity, substantial test-retest agreement, and moderate inter-rater agreement. Practice implications: Results from the iSHARE questionnaires can inform both physician- and patient-directed efforts to improve SDM in clinical practice. Show less

Show moreImmune checkpoint inhibitors targeting the programmed cell death protein 1 (PD-1)/programmed cell death protein ligand 1 (PD-L1) axis have been remarkably successful in inducing tumor remissions in several human cancers, yet a substantial number of patients do not respond to treatment. Because this may be partially due to the mechanisms giving rise to high PD-L1 expression within a patient, it is highly relevant to fully understand these mechanisms. In this study, we conduct a bioinformatic analysis to quantify the relative importance of transcription factor (TF) activity, microRNAs (miRNAs) and mutations in determining PD-L1 (CD274) expression at mRNA level based on data from the Cancer Genome Atlas. To predict individual CD274 levels based on TF activity, we developed multiple linear regression models by taking the expression of target genes of the TFs known to directly target PD-L1 as independent variables. This analysis showed that IRF1, STAT1, NFKB and BRD4 are the most important regulators of CD274 expression, explaining its mRNA levels in 90-98% of the patients. Because the remaining patients had high CD274 levels independent of these TFs, we next investigated whether mutations associated with increased CD274 mRNA levels, and low levels of miRNAs associated with negative regulation of CD274 expression could cause high CD274 levels in these patients. We found that mutations or miRNAs offered an explanation for high CD274 levels in 81-100% of the underpredicted patients. Thus, CD274 expression is largely explained by TF activity, and the remaining unexplained cases can largely be explained by mutations or low miRNA abundance. Show less

Show moreBackground Anti-cancer drugs commonly adversely affect fertility and sexual function. Despite this, patients report a lack of counselling of these potential adverse effects. The aim was to determine Dutch oncologists' knowledge about the adverse effects of various cancer drugs on fertility and sexual function. Methods A cross-sectional survey was sent to members of the Dutch Society for Medical Oncology (n = 433). The survey questions included various cancer drugs' adverse effects on fertility, ovulation, spermatogenesis, and sexual function. Results One hundred and five of 392 oncologists responded (26.8%). Oncologists were more aware of the adverse effects on fertility compared to sexual function. Drugs that were mostly believed to negatively affect fertility were cisplatin (n = 81, 80.2%), epirubicin (n = 78, 78.0%) and cyclophosphamide (n = 80, 77.7%). Regarding sexual function, most mentioned drugs were tamoxifen (n = 67, 65.7%), GnRH-agonists (n = 64, 63.4%) and cisplatin (n = 58, 57.4%). Oncologists with expertise in urology possessed more awareness regarding sexuality-related adverse effects (cisplatin p = 0.038, etoposide p = 0.025, ifosfamide p = 0.06, vinblastine p = 0.000). Conclusion Results revealed that oncologists have different beliefs about possible sexual and fertility-related adverse effects concerning medication resources and literature. Based on our results, oncologists do not possess sufficient knowledge to inform patients about sexual and fertility-related adverse effects. Show less

Show morePart I - Hepatic perfusion for the treatment of unresectable liver metastasesBecause the majority of metastasized uveal melanoma (UM) patients have unresectable liver only metastases, locoregional therapy was developed. In this thesis percutaneous hepatic perfusion (PHP) is described as a treatment for these patients. During this procedure, the chemotherapeutic agent is infused in the hepatic artery and thereby delivered to the liver and metastases directly. Via a veno-venous filtration system, the chemotherapeutic agent is filtered before it reaches the systemic circulation. In this thesis a clinical study was described treating 20 UM patients with metastases confined to the liver with PHP. It was concluded that the results PHP outbalanced the (minimal) toxicity for patients with uveal melanoma metastases.Part II - Tailored care for patients with pancreatic cancerThe poor prognosis of pancreatic cancer did not change much over the last decades, despite the improvements in treatment modalities. Previous studies have reported variations in incidence and mortality in pancreatic cancer between countries worldwide and European countries. A collaboration was initiated across Europe to compare patterns of care and identify best practices for pancreatic cancer care. A core dataset was identified to identificate differences in age, gender, incidence, tumour stage and differences in treatment strategies. To identify any differences in treatment and/or survival of elderly patients with pancreatic cancer, a comparison was performed of data on geriatric pancreatic cancer care and survival with data from the Netherlands and a special ‘Senior Adult Oncology Program’.

Show morePurpose Implementation of patient-reported outcome measures (PROMs) in clinical routine requires knowledge and competences regarding their use. In order to facilitate implementation, an e-learning course for health care professionals (HCPs) on the utilisation of European Organisation for Research and Treatment of Cancer (EORTC) PROMs in oncological clinical practice is being developed. This study aimed to explore future users' educational needs regarding content and learning methods. Methods The sequential mixed methods approach was applied. A scoping literature review informed the guideline for qualitative interviews with HCPs with diverse professional backgrounds in oncology and cancer advocates recruited using a purposive sampling strategy. An international online survey was conducted to validate the qualitative findings. Results Between December 2019 and May 2020, 73 interviews were conducted in 9 countries resulting in 8 topic areas (Basic information on PROs in clinical routine, Benefits of PRO assessments in clinical practice, Implementation of PRO assessments in clinical routine, Setup of PRO assessments for clinical application, Interpretation of PRO data, Integration of PROs into the communication with patients, Use of PROs in clinical practice, Self-management recommendations for patients based on PROs) subsequently presented in the online survey. The online survey (open between 3 June and 19 July 2020) was completed by 233 HCPs from 33 countries. The highest preference was indicated for content on interpretation of PRO data (97%), clinical benefits of assessing PRO data (95.3%) and implementation of routine PRO data assessment (94.8%). Regarding learning methods, participants indicated a high preference for practical examples that use a mixed approach of presentation (written, audio, video and interactive). Conclusion Educational needs for an integration of PROs in communication in clinical care and coherent implementation strategies became evident. These results inform the development of an e-learning course to support HCPs in the clinical use of EORTC PRO measures. Show less

Show moreBackground: The combination treatment regimen of thermal ablation (TA) and transarterial chemoembolization (TACE) has gained a place in treatment of hepatocellular carcinoma (HCC) lesions > 3 cm unsuitable for surgery. Despite a high heterogeneity in the currently used treatment protocols, the pooled results of combined treatments seem to outperform those of TA or TACE alone. TACE preceding TA has been studied extensively, while results of the reverse treatment sequence are lacking. In this retrospective cohort study we compared the two treatment sequences. Patients and methods: 38 patients (median age: 68.5 yrs (range 40-84), male: 34, liver cirrhosis: 33, early stage HCC: 21, intermediate stage HCC: 17) were included in two tertiary referral centers, of whom 27 were treated with TA and adjuvant TACE (TA + TACE). The other 11 patients received TA with neoadjuvant TACE (TACE + TA). Overall survival (OS), time to progression (TTP) and local tumor progression (LTP) free survival were determined for the entire cohort and compared between the two treatment sequences. Results: The median OS of all patients was 52.7 months and the median time to LTP was 11.5 months (censored for liver transplantation). No differences were found with respect to OS between the two treatment sequences. Median time to LTP for TACE + TA was 23.6 months and 8.1 months for TA + TACE (p = 0.19). Discussion: No statistical differences were found for OS, TTP and time to LTP between patients treated with TA combined with neoadjuvant or adjuvant TACE. Show less

Show moreIn this thesis, mathematical modeling and simulation was applied as a tool to inform quantitative decision making in oncology drug discovery and development. Modeling based approaches were shown to be useful to understand the mechanism of action and deconvolve the complexities of novel biotherapeutic modalities being used to treat cancer, including monospecific and bispecific monoclonal antibodies and antibody drug conjugates. Several key observations and learnings were made. For example, modeling was shown to be a useful method to reduce animal experimentation, by enabling in vitro to in vivo correlations or use of simulation to replace experimental methodologies. Mechanism based modeling and simulation was found to be a useful means to translate from preclinical studies to the clinic to ensure progression of the best drug to clinical trials. These models could then be used to optimize design of clinical studies from selection of starting doses to recommended efficacious doses for pivotal trials. Modeling was shown to be beneficial to understand variability in the clinic and to identify factors impacting drug response in individual patients, paving the way for precision medicine strategies, informing clinical diagnostics, biomarkers, and doses for different oncology indications.

Show moreSexuality is a significant quality-of-life concern for many cancer patients. Patients may be disadvantaged if they are not informed and not offered sexual health care. We sought to reveal oncologists' current practice and opinions concerning sexual counselling. The aim of this study was to explore the knowledge, attitude and practice patterns of Dutch medical oncologists regarding treatment-related sexual dysfunction. Questionnaires were sent to 433 members of the Dutch Society of Medical Oncology. The majority (81.5%) of the 120 responding medical oncologists (response rate 30.6%) stated they discussed sexual function with fewer than half of their patients. At the same time, 75.8% of the participating oncologists agreed that addressing sexual function is their responsibility. Sexual function was discussed more often with younger patients and patients with a curative treatment intent. Barriers for avoiding discussing sexual function were lack of time (56.1%), training (49.5%) and advanced age of the patient (50.4%). More than half (64.6%) stated they had little knowledge about the subject and the majority (72.9%) wanted to acquire additional training in sexual function counselling. Medical oncologists accept that sexual function counselling falls within their profession, yet they admit to not counselling patients routinely concerning sexual function. Only in a minority of cases do medical oncologists inform their patients about sexual side effects of treatment. Whether they counsel patients is related to how they view patient's prognosis, patient's age, and self-reported knowledge. Findings indicate there is a role for developing education and practical training. Show less

Show morePurpose Patients with advanced cancer commonly visit the emergency department (ED) during the last 3 months of life. Identification of these patients and their palliative care needs help initiating appropriate care according to patients' wishes. Our objective was to provide insight into ED visits of advanced cancer patients at the end of life. Methods Adult palliative patients with solid tumours who died < 3 months after their ED visit were included (2011-2014). Patients, ED visits, and follow-up were described. Factors associated with approaching death were assessed using Cox proportional hazards models. Results Four hundred twenty patients were included, 54.5% was male, median age 63 years. A total of 54.6% was on systemic anti-cancer treatments and 10.5% received home care >= 1 per day. ED visits were initiated by patients and family in 34.0% and 51.9% occurred during out-of-office hours. Dyspnoea (21.0%) or pain (18.6%) were most reported symptoms. Before the ED visit, limitations on life-sustaining treatments were discussed in 33.8%, during or after the ED visit in 70.7%. Median stay at the ED was 3:29 h (range 00:12-18:01 h), and 319 (76.0%) were hospitalized. Median survival was 18 days (IQ range 7-41). One hundred four (24.8%) died within 7 days after the ED visit, of which 71.2% in-hospital. Factors associated with approaching death were lung cancer, neurologic deterioration, dyspnoea, hypercalcemia, and jaundice. Conclusion ED visits of advanced cancer patients often lead to hospitalization and in-hospital deaths. Timely recognition of patients with limited life expectancies and urgent palliative care needs, and awareness among ED staff of the potential of ED-initiated palliative care may improve the end-of-life trajectory of these patients.

Show moreObjective: To learn how to configure a patient communication aid (PCA) to facilitate shared decision-making (SDM) about treatment for advanced cancer.Methods: The PCA consists of education about SDM, a question prompt list, and values clarification methods. Study 1. A first veersion was presented to 13 patients, 8 relatives and 14 bereaved relatives in interviews. Study 2. A second version was used by 18 patients in a pilot study. Patients and oncologists were interviewed, patients were surveyed, and consultations were audio-recorded.Results: Respondents reported that the aid facilitated patient control over information, raised choice awareness and promoted elaboration. Risks were identified, most importantly that the aid might upset patients. Also, some respondents reported that the PCA did not, or would not support decision making because they felt sufficiently competent, did not perceive a role for themselves, or did not perceive that the decision required elaboration.Conclusions: Opinions on the usefulness of the PCA varied. It was challenging to raise awareness about the presence of a choice, and to find a balance between comprehensive information and sensitivity.Practice implications: A future study should demonstrate whether the PCA can improve SDM, and whether this effect is stronger when oncologists receive training.
