Show morePrognostic information is needed to balance benefits and risks of cancer treatment in older patients. Metabolomics-based scores were previously developed to predict 5- and 10-year mortality (MetaboHealth) and biological age (MetaboAge). This study aims to investigate the association of MetaboHealth and MetaboAge with 1-year mortality in older patients with solid tumors, and to study their predictive value for mortality in addition to established clinical predictors. This prospective cohort study included patients aged ≥ 70 years with a solid malignant tumor, who underwent blood sampling and a geriatric assessment before treatment initiation. The outcome was all-cause 1-year mortality. Of the 192 patients, the median age was 77 years. With each SD increase of MetaboHealth, patients had a 2.32 times increased risk of mortality (HR 2.32, 95% CI 1.59–3.39). With each year increase in MetaboAge, there was a 4% increased risk of mortality (HR 1.04, 1.01–1.07). MetaboHealth and MetaboAge showed an AUC of 0.66 (0.56–0.75) and 0.60 (0.51–0.68) for mortality prediction accuracy, respectively. The AUC of a predictive model containing age, primary tumor site, distant metastasis, comorbidity, and malnutrition was 0.76 (0.68–0.83). Addition of MetaboHealth increased AUC to 0.80 (0.74–0.87) (p = 0.09) and AUC did not change with MetaboAge (0.76 (0.69–0.83) (p = 0.89)). Higher MetaboHealth and MetaboAge scores were associated with 1-year mortality. The addition of MetaboHealth to established clinical predictors only marginally improved mortality prediction in this cohort with various types of tumors. MetaboHealth may potentially improve identification of older patients vulnerable for adverse events, but numbers were too small for definitive conclusions. The TENT study is retrospectively registered at the Netherlands Trial Register (NTR), trial number NL8107. Date of registration: 22–10-2019. Show less

Show morePURPOSEDPYD-guided fluoropyrimidine dosing improves patient safety in carriers of DPYD variant alleles. However, the impact on treatment outcome in these patients is largely unknown. Therefore, progression-free survival (PFS) and overall survival (OS) were compared between DPYD variant carriers treated with a reduced dose and DPYD wild-type controls receiving a full fluoropyrimidine dose in a retrospective matched-pair survival analysis.METHODSData from a prospective multicenter study (ClinicalTrials.gov identifier: NCT02324452) in which DPYD variant carriers received a 25% (c.1236G>A and c.2846A>T) or 50% (DPYD*2A and c.1679T>G) reduced dose and data from DPYD variant carriers treated with a similarly reduced dose of fluoropyrimidines identified during routine clinical care were obtained. Each DPYD variant carrier was matched to three DPYD wild-type controls treated with a standard dose. Survival analyses were performed using Kaplan-Meier estimates and Cox regression.RESULTSIn total, 156 DPYD variant carriers and 775 DPYD wild-type controls were available for analysis. Sixty-one c.1236G>A, 25 DPYD*2A, 13 c.2846A>T, and-when pooled-93 DPYD variant carriers could each be matched to three unique DPYD wild-type controls. For pooled DPYD variant carriers, PFS (hazard ratio [HR], 1.23; 95% CI, 1.00 to 1.51; P = .053) and OS (HR, 0.95; 95% CI, 0.75 to 1.51; P = .698) were not negatively affected by DPYD-guided dose individualization. In the subgroup analyses, a shorter PFS (HR, 1.43; 95% CI, 1.10 to 1.86; P = .007) was found in c.1236G>A variant carriers, whereas no differences were found for DPYD*2A and c.2846A>T carriers.CONCLUSIONIn this exploratory analysis, DPYD-guided fluoropyrimidine dosing does not negatively affect PFS and OS in pooled DPYD variant carriers. Close monitoring with early dose modifications based on toxicity is recommended, especially for c.1236G>A carriers receiving a reduced starting dose. Show less

Show moreBackground: Fear of cancer recurrence (FCR) is one of the greatest problems with which cancer survivors have to deal. High levels of FCR are characterized by intrusive thoughts about cancer-related events and re-experiencing these events, avoidance of reminders of cancer, and hypervigilance, similar to post-traumatic stress disorder (PTSD). Eye movement desensitization and reprocessing (EMDR) therapy focuses on these images and memories. It is effective in reducing PTSD and may be effective in reducing high levels of FCR. Objective: The aim of the present study is to investigate the effectiveness of EMDR for severe FCR in breast and colorectal cancer survivors. Method: A multiple-baseline single-case experimental design (n = 8) was used. Daily repeated measurements for FCR were taken during the baseline phase and treatment phase, post-treatment, and at the 3 month follow-up. Participants answered the Cancer Worry Scale (CWS) and the Fear of Cancer Recurrence Inventory, Dutch version (FCRI-NL) five times, i.e. at the start and at the end of each phase (baseline, treatment, post-treatment, and follow-up). The study was prospectively registered at clinicaltrials.gov (NL8223). Results: Visual analysis and effect size calculation by Tau-U were executed for the daily questionnaire on FCR. The weighted average Tau-U score was .63 (p < .01) for baseline versus post-treatment, indicating large change, and .53 (p < .01) between baseline and follow-up, indicating moderate change. The scores on the CWS and FCRI-NL-SF decreased significantly from baseline to follow-up. Conclusion: The results seem promising for EMDR therapy as a potentially effective treatment for FCR. Further research is recommended. Show less

Show moreImportance Although older patients are at increased risk of developing grade 3 or higher chemotherapy-related toxic effects, no studies, to our knowledge, have focused on the association between toxic effects and quality of life (QOL) and physical functioning.Objective To investigate the association between grade 3 or higher chemotherapy-related toxic effects and QOL and physical functioning over time in older patients.Design, Setting, and Participants In this prospective, multicenter cohort study, patients aged 70 years or older who were scheduled to receive chemotherapy with curative or palliative intent and a geriatric assessment were included. Patients were treated with chemotherapy between December 2015 and December 2021. Quality of life and physical functioning were analyzed at baseline and after 6 months and 12 months.Exposures Common Terminology Criteria for Adverse Events grade 3 or higher chemotherapy-related toxic effects.Main Outcomes and Measures The main outcome was a composite end point, defined as a decline in QOL and/or physical functioning or mortality at 6 months and 12 months after chemotherapy initiation. Associations between toxic effects and the composite end point were analyzed with multivariable logistic regression models.Results Of the 276 patients, the median age was 74 years (IQR, 72-77 years), 177 (64%) were male, 196 (71%) received chemotherapy with curative intent, and 157 (57%) had gastrointestinal cancers. Among the total patients, 145 (53%) had deficits in 2 or more of the 4 domains of the geriatric assessment and were classified as frail. Grade 3 or higher toxic effects were observed in 94 patients (65%) with frailty and 66 (50%) of those without frailty (P = .01). Decline in QOL and/or physical functioning or death was observed in 76% of patients with frailty and in 64% to 68% of those without frailty. Among patients with frailty, grade 3 or higher toxic effects were associated with the composite end point at 6 months (odds ratio [OR], 2.62; 95% CI, 1.14-6.05) but not at 12 months (OR, 1.09; 95% CI, 0.45-2.64) and were associated with mortality at 12 months (OR, 3.54; 95% CI, 1.50-8.33). Toxic effects were not associated with the composite end point in patients without frailty (6 months: OR, 0.76; 95% CI, 0.36-1.64; 12 months: OR, 1.06; 95% CI, 0.46-2.43).Conclusions and Relevance In this prospective cohort study of 276 patients aged 70 or older who were treated with chemotherapy, patients with frailty had more grade 3 or higher toxic effects than those without frailty, and the occurrence of toxic effects was associated with a decline in QOL and/or physical functioning or mortality after 1 year. Toxic effects were not associated with poor outcomes in patients without frailty. Pretreatment frailty screening and individualized treatment adaptions could prevent a treatment-related decline of remaining health. Show less

Show moreAdults aged =80 years (the oldest-old) comprise the fastest growing age group in Western populations. Yet little is known about their cancer burden. In this nation-wide study, we assessed their trends in incidence, treatment and survival over a 30-year period, and predicted their future cancer incidence. All 2 468 695 incident cancer cases during 1990 to 2019 were selected from the Netherlands Cancer Registry, of whom 386 611 were diagnosed in the oldest-old (16%). The incidence of the oldest-old was predicted until 2032. Net and overall survival (OS) were calculated. Patients were divided into four age groups (<80, 80-84, 85-89 and =90 years). The incidence of the oldest-old doubled between 1990 and 2019 and is expected to grow annually with 5% up to 2032. In virtually all cancers the share of oldest-old patients grew, but declined for prostate cancer (25% in 1990-1994 vs 13% in 2015-2019). The proportion of undetermined disease stage increased with age in most cancers. The application of systemic therapy increased, albeit less pronounced in the oldest-old than their younger counterparts (1990 vs 2019: 12%-34%, 3%-15%, 2%-7% and 1%-3% in <80, 80-84, 85-89 and =90 years old). Five-year OS of the oldest-old patients increased by 7 percentage points (to 26%) between 1990 to 1994 and 2015 to 2019 compared to 19 percentage points (to 63%) in <80 years old. The oldest-old cancer patients are a rapidly growing group who benefitted less from improvements in cancer treatment than younger patients, reflecting the multiple challenges faced in the care of the oldest-old.

Show moreIntroduction: As the population is ageing, the number of older patients with multimorbidity including cancer continues to increase. To improve care for these patients, the European Union-funded project "Streamlined Geriatric and Oncological evaluation based on IC Technology" (GERONTE) was initiated to develop a new, patientcentred, holistic care pathway. The aim of this paper is to analyse what challenges are encountered in everyday clinical practice according to patients, their informal caregivers, and healthcare professionals as a starting point for the development of the care pathway.Materials and Methods: An expert panel of cancer and geriatrics specialists participated in an online survey to answer what challenges they experience in caring for older patients with multimorbidity including cancer and what treatment outcomes could be improved. Furthermore, in-depth interviews with older patients and their informal caregivers were organised to assess what challenges they experience.Results: Healthcare professionals (n = 36) most frequently mentioned the challenge of choosing the best treatment in light of the lack of evidence in this population and how to handle interactions between the (cancer) treatment and multimorbidities. Twelve patients and caregivers participated, and they most frequently mentioned challenges related to treatment outcomes, such as how to deal with symptoms of disease or treatment and how to maintain quality of life. From the challenges, five main themes emerged that should be taken into account when developing a new care pathway for older patients with multimorbidity including cancer. Two themes focus on decision making aspects such as personalized treatment recommendations and inclusion of nononcologic information, two focus on patient support and monitoring to maintain quality of life and functioning, and one overarching theme addresses care coordination to prevent fragmentation of care.Discussion: In conclusion, the management of older patients with multimorbidity including cancer is complex and although progress has been made on improving aspects of their care, challenges remain and patients are at risk of receiving inappropriate, unnecessary, and potentially harmful treatment. A patient-centred care pathway that integrates solutions to the five main themes and that moves away from a single-disease centred approach is needed. Show less

Show moreMost cancers occur in older people and the burden in this age group is increasing. Over the past two decades the evidence on how best to treat this population has increased rapidly. However, implementation of new best practices has been slow and needs involvement of policymakers. This perspective paper explains why older people with cancer have different needs than the wider population. An overview is given of the recommended approach for older people with cancer and its benefits on clinical outcomes and cost-effectiveness. In older patients, the geriatric assessment (GA) is the gold standard to measure level of fitness and to determine treatment tolerability. The GA, with multiple domains of physical health, functional status, psychological health and socio-environmental factors, prevents initiation of inappropriate oncologic treatment and recommends geriatric interventions to optimize the patient's general health and thus resilience for receiving treatments. Multiple studies have proven its benefits such as reduced toxicity, better quality of life, better patient-centred communication and lower healthcare use. Although GA might require investment of time and resources, this is relatively small compared to the improved outcomes, possible cost-savings and compared to the large cost of oncologic treatments as a whole.

Show moreIntroduction: Polypharmacy is common in older adults with cancer and is associated with drug related problems (DRPs) and potentially inappropriate medication (PIM). We introduced a medication optimization care pathway for older adults with advanced cancer and a limited life expectancy and studied the prevalence of DRPs and PIMs as well as the adherence to medication-related recommendations and the patient satisfaction. Materials and Methods: A medication review was performed in patients aged >65 years with polypharmacy and a life expectancy of <24 months. Recommendations on adjustments of medication were discussed in a multidisciplinary team including a pharmacist, an oncologist, and a geriatrician. Implementation of the recommendations was left to the discretion of the oncologist. Four weeks after the implementation, the patient filled a questionnaire to assess satisfaction.Results: One hundred twenty patients were included. The mean age was 75 years and 39% were female. A mean of 12 medications was used. The median number of DRP was 6.0 per patient and median number of PIMs was 3.0 per patient. Overtreatment accounted for 26% of DRP and the most frequently involved drug classes were antihypertensive medication (22%), non-opioid analgesics (22%), and antilipemics (12%). The multidisciplinary team accepted 78% of the recommendations of the pharmacist and the oncologist implemented 54% of the recommendations. Overall, patients were satisfied or very satisfied with the intervention.Discussion: DRPs and PIMs are highly prevalent in this population and can be reduced by a multidisciplinary medication optimization intervention. Patients appreciate the medication optimization intervention and are satisfied with the intervention. Show less

Show moreIntroductionIn recent years, primary surgical treatment of older women with non-metastatic breast cancer has decreased in favor of primary endocrine therapy (PET). PET can be considered in women with a remaining life expectancy of less than five years. The aim of this study was to (1) assess the risk of distant metastases and other cause mortality over ten years in women aged 65 and older with stage I-III breast cancer treated with PET, (2) whether this was associated with geriatric characteristics and comorbidities and to (3) describe the reasons on which the choice for PET was made.MethodsWomen were included from the retrospective FOCUS cohort, which comprises all incident women diagnosed with breast cancer aged 65 or older between January 1997 and December 2004 in the Comprehensive Cancer Center Region West in the Netherlands. We selected women (N = 257) with stage I-III breast cancer and treated with PET from this cohort. Patient characteristics (including comorbidity, polypharmacy, walking, cognitive and sensory impairment), treatment and tumor characteristics were retrospectively extracted from charts. Outcomes were distant metastasis and other cause mortality. Cumulative incidences were calculated using the Cumulative Incidence for Competing Risks method (CICR); and subdistribution hazard ratios (SHR) were tested between groups based on age, geriatric characteristics and comorbidity with the Fine and Gray model.ResultsWomen treated with PET were on average 84 years old and 41% had one or more geriatric characteristics. Other cause mortality exceeded the cumulative incidence of distant metastasis over ten years (83 versus 5.6%). The risk of dying from another cause further increased in women with geriatric characteristics (SHR 2.06, p < 0.001) or two or more comorbidities (SHR 1.72, p < 0.001). Often the reason for omitting surgery was not recorded (52.9%), but if recorded surgery was omitted mainly at the patient's request (18.7%).DiscussionThis study shows that the cumulative incidence of distant metastasis is much lower than other cause mortality in older women with breast cancer treated with PET, especially in the presence of geriatric characteristics or comorbidities. This confirms the importance of assessment of geriatric characteristics to aid counseling of older women. Show less

Show moreBackground: Even though antithrombotic therapy has probably little or even negative effects on the well-being of people with cancer during their last year of life, deprescribing antithrombotic therapy at the end of life is rare in practice. It is often continued until death, possibly resulting in excess bleeding, an increased disease burden and higher healthcare costs.Methods: The SERENITY consortium comprises researchers and clinicians from eight European countries with specialties in different clinical fields, epidemiology and psychology. SERENITY will use a comprehensive approach combining a realist review, flash mob research, epidemiological studies, and qualitative interviews. The results of these studies will be used in a Delphi process to reach a consensus on the optimal design of the shared decision support tool. Next, the shared decision support tool will be tested in a randomised controlled trial. A targeted implementation and dissemination plan will be developed to enable the use of the SERENITY tool across Europe, as well as its incorporation in clinical guidelines and policies. The entire project is funded by Horizon Europe.Results: SERENITY will develop an information-driven shared decision support tool that will facilitate treatment decisions regarding the appropriate use of antithrombotic therapy in people with cancer at the end of life.Conclusions: We aim to develop an intervention that guides the appropriate use of antithrombotic therapy, prevents bleeding complications, and saves healthcare costs. Hopefully, usage of the tool leads to enhanced empowerment and improved quality of life and treatment satisfaction of people with advanced cancer and their care givers. Show less

Show moreBackground: There is a lack of information on mental health outcomes for the increasing older population. Therefore, the aim of the current study is to assess depressive symptoms, loneliness, and apathy in older patients with breast cancer within the first 5 years after diagnosis.Methods: Women aged >= 70 years with early-stage breast cancer were included. Multivariate linear mixed models were used to assess longitudinal changes in symptoms of depression (according to the 15-item Geriatric Depression Scale), loneliness (according to the De Jong Gierveld Loneliness Scale) and apathy (according to the Starkstein Apathy Scale) over time at 3, 9, 15, 27 and 60 months follow-up.Results: In total, 299 patients were included (mean [standard deviation (SD)] age: 75.8 [5.2] years). At 3 months follow-up, shortly after the acute treatment, 10% of patients had sig-nificant depressive symptoms, while loneliness and apathy were present in 31% and 41% of all patients, respectively. Depression, loneliness and apathy scores showed no clinically relevant changes over time in the whole cohort. Patients who received adjuvant systemic therapies (i.e. endocrine therapy and/or chemotherapy and/or targeted therapy (trastuzumab)) had si-milar mental health outcomes as those who did not. However, frail patients had more symptoms (p < 0.001) and were more prone to develop depressive symptoms over time than non-frail patients (p = 0.002).Discussion: Depression, loneliness and apathy were frequently observed in older women with breast cancer and did not change over time. Patients who received adjuvant systemic therapies had similar mental health outcomes as those who did not. However, frail patients were at higher risk to experience these symptoms.(c) 2023 The Author(s). Published by Elsevier Ltd.

Show moreBackgroundWe aimed to study the pharmacokinetics and -dynamics of tamoxifen in older women with non-metastatic breast cancer.MethodsData for this analysis were derived from the CYPTAM study (NTR1509) database. Patients were stratified by age (age groups < 65 and 65 and older). Steady-state trough concentrations were measured of tamoxifen, N-desmethyltamoxifen, 4-hydroxy-tamoxifen, and endoxifen. CYP2D6 and CYP3A4 phenotypes were assessed for all patients by genotyping. Multiple linear regression models were used to analyze tamoxifen and endoxifen variability. Outcome data included recurrence-free survival at time of tamoxifen discontinuation (RFSt) and overall survival (OS).Results668 patients were included, 141 (21%) were 65 and older. Demographics and treatment duration were similar across age groups. Older patients had significantly higher concentrations of tamoxifen 129.4 ng/ml (SD 53.7) versus 112.2 ng/ml (SD 42.0) and endoxifen 12.1 ng/ml (SD 6.6) versus 10.7 ng/ml (SD 5.7, p all < 0.05), independently of CYP2D6 and CYP3A4 gene polymorphisms. Age independently explained 5% of the variability of tamoxifen (b = 0.95, p < 0.001, R-2 = 0.051) and 0.1% of the variability in endoxifen concentrations (b = 0.45, p = 0.12, R-2 = 0.007). Older patients had worse RFSt (5.8 versus 7.3 years, p = 0.01) and worse OS (7.8 years versus 8.7 years, p = 0.01). This was not related to differences in endoxifen concentration (HR 1.0, 95% CI 0.96-1.04, p = 0.84) or CYP polymorphisms.ConclusionSerum concentrations of tamoxifen and its demethylated metabolites are higher in older patients, independent of CYP2D6 or CYP3A4 gene polymorphisms. A higher bioavailability of tamoxifen in older patients may explain the observed differences. However, clinical relevance of these findings is limited and should not lead to a different tamoxifen dose in older patients. Show less

Show moreBackground: Trends of surgical and non-surgical complications among the old, older and oldest patients after colorectal cancer (CRC) surgery could help to identify the best target outcome to further improve postoperative outcome.Materials and methods: All consecutive patients >= 70 years receiving curative elective CRC resection between 2011 and 2019 in The Netherlands were included. Baseline variables and postoperative com-plications were prospectively collected by the Dutch ColoRectal audit (DCRA). We assessed surgical and non-surgical complications over time and within age categories (70-74, 75-79 and >= 80 years) and determined the impact of age on the risk of both types of complications by using multivariate logistic regression analyses. Results: Overall, 38648 patients with a median age of 76 years were included. Between 2011 and 2019 the proportion of ASA score >= 3 and laparoscopic surgery increased. Non-surgical complications signif-icantly improved between 2011 (21.8%) and 2019 (17.1%) and surgical complications remained constant (from 17.6% to 16.8%). Surgical complications were stable over time for each age group. Non-surgical complications improved in the oldest two age groups. Increasing age was only associated with non-surgical complications (75-79 years; OR 1.17 (95% CI 1.10-1.25), >= 80 years; OR 1.46 (95% CI 1.37-1.55) compared to 70-74 years), not with surgical complications. Conclusion: The reduction of postoperative complications in the older CRC population was predomi-nantly driven by a decrease in non-surgical complications. Moreover, increasing age was only associated with non-surgical complications and not with surgical complications. Future care developments should focus on non-surgical complications, especially in patients >= 75 years.(c) 2022 Elsevier Ltd, BASO -The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Show moreBackground A decline in physical activity and the ability to perform activities of daily living (ADL) and instrumental activities of daily living (IADL) could interfere with independent living and quality of life in older patients, but may be prevented with tailored interventions. The aim of the current study was to assess changes in physical activity and ADL/IADL in the first 5 years after breast cancer diagnosis in a real-world cohort of older patients and to identify factors associated with physical decline. Methods Patients aged >= 70 years with in situ or stages I-III breast cancer were included in the prospective Climb Every Mountain cohort study. Linear mixed models were used to assess physical activity (according to Metabolic Equivalent of Task (MET) hours per week) and ADL/IADL (according to the Groningen Activity Restriction Scale (GARS)) over time. Secondly, the association with geriatric characteristics, treatment, quality of life, depression, apathy, and loneliness was analyzed. Results A total of 239 patients were included. Physical activity and ADL/IADL changed in the first 5 years after diagnosis (mean change from baseline -11.6 and +4.2, respectively). Geriatric characteristics at baseline were strongly associated with longitudinal change in physical activity and ADL/IADL, whereas breast cancer treatment was not. A better quality of life was associated with better physical activity and preservation of ADL/IADL, while depression and loneliness were negatively associated with these outcomes. Discussion Geriatric characteristics, loneliness, and depressive symptoms were associated with physical decline in older patients with breast cancer, while breast cancer treatment was not.A decline in physical activity and the ability to perform activities of daily living may interfere with quality of life in older patients. This article assessed changes in physical activity and activities of daily living in the first 5 years after breast cancer diagnosis in a real-world cohort of older patients and identified factors associated with physical decline.

Show moreIntroduction: Studies investigating the long-term effects of breast cancer treatment on cognition in older women with breast cancer are lacking, even though preserving cognition is highly valued by the older population. Specifically, concerns have been raised regarding the detrimental effects of endocrine therapy (ET) on cognition. Therefore, we investigated cogni-tive functioning over time and predictors for cognitive decline in older women treated for early breast cancer.Methods: We prospectively enrolled Dutch women aged >70 years with stage I-III breast can-cer in the observational CLIMB study. The Mini-Mental State Examination (MMSE) was performed before ET initiation and after 9, 15 and 27 months. Longitudinal MMSE scores were analysed and stratified for ET. Linear mixed models were used to identify possible pre-dictors of cognitive decline.Results: Among the 273 participants, the mean age was 76 years (standard deviation 5), and 48% received ET. The mean baseline MMSE score was 28.2 (standard deviation 1.9). Cogni-tion did not decline to clinically meaningful differences, irrespective of ET. MMSE scores of women with pre-treatment cognitive impairments slightly improved over time (significant interaction terms) in the entire cohort and in women receiving ET. High age, low educational level and impaired mobility were independently associated with declining MMSE scores over time, although the declines were not clinically meaningful.Conclusion: Cognition of older women with early breast cancer did not decline in the first two years after treatment initiation, irrespective of ET. Our findings suggest that the fear of declining cognition does not justify the de-escalation of breast cancer treatment in older women. 2023 The Authors. Published by Elsevier Ltd.

The use of high dose systemic corticosteroids around docetaxel infusion appeared to decrease the incidence of HSR and fluid retention and has been applied in daily practice ever since. However, there is little evidence that supports this high dose of dexamethasone. Furthermore, the application of high-dosed corticosteroids can lead to undesirable adverse effects. In this phase 1 study, we aim to evaluate the impact of reducing the dose of dexamethasone as an adjunct to docetaxel on the incidence of HSR and fluid retention in patients with prostate or breast cancer. Background: There is little evidence that supports the registered high dose of dexamethasone used around docetaxel. However, this high dose is associated with considerable side effects. This study evaluates the feasibility of reducing the prophylactic oral dosage of dexamethasone around docetaxel infusion. Patients and methods: Eligible patients had a histologically confirmed diagnosis of prostate or breast cancer and had received at least three cycles of docetaxel as monotherapy or combination therapy. Prophylactic dexamethasone around docetaxel infusion was administered in a de-escalating order per cohort of patients. Primary endpoint was the occurrence of grade III/IV fluid retention and hypersensitivity reactions (HSRs). Results: Of the 46 enrolled patients, 39 were evaluable (prostate cancer (n = 25), breast cancer (n = 14). In patients with prostate cancer, the dosage of dexamethasone was reduced to a single dose of 4 mg; in patients with breast cancer, the dosage was reduced to a 3-day schedule of 4 mg-8 mg-4 mg once daily, after which no further reduction has been tested. None of the 39 patients developed grade III/IV fluid retention or HSR. One patient (2.6%) had a grade 1 HSR, and there were six patients (15.4%) with grade I or II edema. There were no differences in quality of life (QoL) between cohorts. Conclusions: It seems that the prophylactic dose of dexamethasone around docetaxel infusion can be safely reduced with respect to the occurrence of grade III/IV HSRs or the fluid retention syndrome.

Show moreIntroduction: Vulvar cancer is a disease that mainly affects older women. Frailty is an important predictor of outcomes and geriatric assessment can help tailor treatment decisions and improve outcomes. This study aims to assess the prevalence of frailty in older women with vulvar cancer, and how it relates to integrated geriatric care and treatment according to the oncological guidelines. Materials and Methods: A single-center cohort study was performed, among patients 70 years and older, who were diagnosed with vulvar cancer at Leiden University Medical Center, between January 2012 and May 2020. Data on geriatric assessment, treatment decision-making and treatment-related outcomes were collected. Results: Our study included 114 patients. Mean age was 79.7 years, and 52 patients (45.6%) were frail. Of the frail patients, 42.0% were referred to a geriatrician. In eight of these cases, the geriatrician was actively involved in weighing the benefit and harm of standard oncological treatment versus de-escalated treatment. Frailty, higher age, impairment in the somatic domain, cognitive impairment, and functional dependency were associated with referral to a geriatrician and with active involvement of a geriatrician in decision making. In 26 of frail patients (50.0%) oncological treatment was de-escalated. Frailty, higher age, impairment in the somatic domain, cognitive impairment, and functional dependency were associated with de-escalation of treatment. De-escalated treatment did not compromise survival. Discussion: Frailty is prevalent among older women with vulvar cancer and is associated with referral to a geriatrician and de-escalation of oncological treatment. While this reflects that it is deemed important to tailor treatment decision for frail patients, most frail patients are not routinely evaluated by a geriatrician. Further multidisciplinary collaboration and research is necessary to optimize tailored treatment decisions for this patient group. Show less

Show moreNew treatment strategies have improved survival of metastatic colorectal cancer in trials. However, it is not clear whether older patients benefit from these novel therapies, as they are often not included in pivotal trials. Therefore, we investigated treatment patterns and overall survival over time in older patients with metastatic colorectal cancer in a population-based study. We identified 22.192 Dutch patients aged & GE;70 years diagnosed with synchronous metastatic colorectal cancer between 2005 and 2020 from the Netherlands Cancer Registry. Changes in treatment over time were assessed with logistic regression models. Survival was assessed by Cox proportional hazard ratios (HR). Results showed that chemotherapy use increased between 2005 and 2015, but declined from 2015 onwards, while more patients received best supportive care. Over time, fewer patients underwent primary tumor resection alone. Although survival of both metastatic colon and rectal cancer improved until 2014, survival of colon cancer decreased from 2014 onwards (HR 1.04, 95% confidence interval [CI] 1.01-1.05), which was seen in all age groups. Survival of metastatic rectal cancer patients remained unchanged from 2014 onwards (HR 1.00, 95% CI 0.98-1.03) in all age groups. In conclusion, treatment patterns of Dutch older patients with synchronous metastatic colorectal cancer rapidly changed from 2005 to 2020, with increasing percentages of patients receiving best supportive care. Survival of metastatic colon cancer decreased from 2014 onwards. The implementation of a colorectal cancer screening program and patient selection might explain why only a subset of older patients seem to benefit from the availability of novel treatment options.

Show moreBackground: Gene expression signatures have emerged to predict prognosis and guide the use of adjuvant therapy in patients with hormone receptor-positive breast cancer. The objective of this systematic review was to evaluate the prognostic and predictive value of commercially available gene expression signatures as a tool in adjuvant treatment decision-making in older patients with breast cancer.Methods: PubMed, MEDLINE, Embase, Web of Science, Cochrane Library, and Emcare were reviewed for relevant articles published before December 2021. Eligible studies were randomised trials and cohort studies that externally validated commercially available gene expression signatures in patients aged 65 years and older, including studies that presented subanalyses of this age group. Data extraction and risk of bias assessment was performed independently by two investigators.Results: Fifteen studies were included. Most studies investigated Oncotype DX, while results from other gene expression signatures were limited. Several studies underlined the prognostic performance of Oncotype DX and Prosigna Risk of Recurrence in older patients. Moreover, Oncotype DX was predictive for older patients with an intermediate-risk recurrence score; chemotherapy could be spared in both lymph node-positive and lymph node -negative disease.Conclusions: Prognostic performance has been demonstrated in older patients for several gene expression sig-natures. However, additional validation in patients with high-risk tumours is needed before gene expression signatures can be implemented in clinical practice as a prediction tool for adjuvant chemotherapy decision -making in the older age group.
