Determining clinically important differences in health-related quality of life in older patients with cancer undergoing chemotherapy or surgery.

PURPOSE: Using the EORTC Global Health Status (GHS) scale, we aimed to determine minimal clinically important differences (MCID) in health-related quality of life (HRQOL) changes for older cancer patients with a geriatric risk profile, as defined by the geriatric 8 (G8) health screening tool, undergoing treatment. Simultaneously, we assessed baseline patient characteristics prognostic for HRQOL changes. METHODS: Our analysis included 1424 (G8 ≤ 14) older patients with cancer scheduled to receive chemotherapy (n = 683) or surgery (n = 741). Anchor-based methods, linking the GHS score to clinical indicators, were used to determine MCID between baseline and follow-up at 3 months. A threshold of 0.2 standard deviation (SD) was used to exclude MCID estimates too small for interpretation. Logistic regressions analysed baseline patient characteristics prognostic for HRQOL changes. RESULTS: The 15-item Geriatric Depression Scale (GDS15), Visual Analogue Scale (VAS) for Fatigue and ECOG Performance Status (PS) were selected as clinical anchors. In the surgery group, MCID estimates for improvement and deterioration were ECOG PS (5*, 11*), GDS15 (5*, 2) and VAS Fatigue (3, 9*). In the chemotherapy group, MCID estimates for improvement and deterioration were ECOG PS (8*, 7*), GDS15 (5, 4) and VAS Fatigue (5, 5*). Estimates with * were > 0.2 SD threshold. Patients experiencing pain or malnutrition (surgery group) or fatigue (chemotherapy group) at baseline showed a significantly stable or improved HRQOL (p < 0.05) after their treatment. CONCLUSION: The reported MCID for improvement and deterioration depended on the anchor used and treatment received. The estimates can be used to evaluate significant changes in HRQOL and to determine sample sizes in clinical trials.

Adherence to geriatric assessment-based recommendations in older patients with cancer: a multicenter prospective cohort study in Belgium.

Background: In the general older population, geriatric assessment (GA)-guided treatment plans can improve overall survival, quality of life and functional status (FS). In GA-related research in geriatric oncology, studies mainly focused on geriatric screening and GA but not on geriatric recommendations, interventions and follow-up. The aim of this study was to investigate the adherence to geriatric recommendations and subsequent actions undertaken in older patients with cancer. Patient and methods: A prospective Belgian multicenter (N = 22) cohort study included patients ≥70 years with a malignant tumor upon oncologic treatment decision. Patients with an abnormal result on the geriatric screening (G8 ≤14/17) underwent GA. Geriatric recommendations were formulated based on GA results. At follow-up the adherence to geriatric recommendations was documented including a description of actions undertaken. Results: From November 2012 till February 2015, G8 screening was carried out in 8451 patients, of which 5838 patients had an abnormal result. Geriatric recommendations data were available for 5631 patients. Geriatric recommendations were made for 4459 patients. Geriatric interventions data were available for 4167 patients. A total of 12 384 geriatric recommendations were made. At least one different geriatric recommendation was implemented in 2874 patients. A dietician, social worker and geriatrician intervened most frequently for problems detected on the nutritional, social and functional domain. A total of 7569 actions were undertaken for a total of 5725 geriatric interventions, most frequently nutritional support and supplements, extended home care and psychological support. Conclusions: This large-scale Belgian study focuses on the adherence to geriatric recommendations and subsequent actions undertaken and contributes to the optimal management of older patients with cancer. We identified the domains for which geriatric recommendations are most frequently made and adhered to, and which referrals to other health care workers and facilities are frequently applied in the multidisciplinary approach of older patients with cancer.

Postoperative complications in individuals aged 70 and over undergoing elective surgery for colorectal cancer.

AIM: This study aims to describe the nature, incidence, severity and outcomes of in-hospital postoperative complications (POCs) in older patients undergoing elective surgery for colorectal cancer. METHOD: Patients ≥ 70 years old were identified from a prospectively collected database (2009-2015) focusing on the implementation of geriatric screening and assessment in patients with cancer. Medical and surgical POCs were retrieved retrospectively from the medical records, and the severity of the POCs was graded by the Clavien-Dindo (CD) grading system. The following outcomes were analysed comparing patients with and without CD ≥ 2 and CD ≥ 3 POCs: length of stay (LOS), transfer to the intensive care unit, 30-day readmission rates, 30-day and 1-year mortality. RESULTS: In the 190 patients included, medical POCs (40.5%) were more frequent than surgical POCs (17.9%), and 37.9% experienced CD ≥ 2 POCs. The most common medical POCs were infections (26.8%), transient confusion or altered mental function (12.1%), cardiac arrhythmia (4.7%), and ileus/gastroparesis/prolonged recovery of transit (4.7%). The most common surgical POCs were surgical site infections (12.1%), wound dehiscence/bleeding (4.7%), anastomotic leak (3.7%) and surgical site bleeding (3.7%). The reoperation rate was 7.9%. CD ≥ 2 POCs led to 11 intensive care unit admissions and increased median postoperative LOS by 114% (P < 0.0001 for both), but did not significantly alter 30-day readmission and 30-day and 1-year mortality rates. CD ≥ 3 POCs increased LOS by 162% (P < 0.0001) and showed an increased 1-year mortality (P = 0.07). CONCLUSION: This study shows that in-hospital medical and surgical complications after surgery for colorectal cancer in patients ≥ 70 years old are frequent and that complications lead to less favourable outcomes.

Geriatric Assessment and Functional Decline in Older Patients with Lung Cancer.

PURPOSE: Older patients with lung cancer are a heterogeneous population making treatment decisions complex. This study aims to evaluate the value of geriatric assessment (GA) as well as the evolution of functional status (FS) in older patients with lung cancer, and to identify predictors associated with functional decline and overall survival (OS). METHODS: At baseline, GA was performed in patients ≥70 years with newly diagnosed lung cancer. FS measured by activities of daily living (ADL) and instrumental activities of daily living (IADL) was reassessed at follow-up to define functional decline and OS was collected. Predictors for functional decline and OS were determined. RESULTS: Two hundred and forty-five patients were included in this study. At baseline, GA deficiencies were present in all domains and ADL and IADL were impaired in 51 and 63% of patients, respectively. At follow-up, functional decline in ADL was observed in 23% and in IADL in 45% of patients. In multivariable analysis, radiotherapy was predictive for ADL decline. No other predictors for ADL or IADL decline were identified. Stage and baseline performance status were predictive for OS. CONCLUSIONS: Older patients with lung cancer present with multiple deficiencies covering all geriatric domains. During treatment, functional decline is observed in almost half of the patients. None of the specific domains of the GA were predictive for functional decline or survival, probably because of the high impact of the aggressiveness of this tumor type leading to a poor prognosis.

Screening tools for multidimensional health problems warranting a geriatric assessment in older cancer patients: an update on SIOG recommendations†.

BACKGROUND: Screening tools are proposed to identify those older cancer patients in need of geriatric assessment (GA) and multidisciplinary approach. We aimed to update the International Society of Geriatric Oncology (SIOG) 2005 recommendations on the use of screening tools. MATERIALS AND METHODS: SIOG composed a task group to review, interpret and discuss evidence on the use of screening tools in older cancer patients. A systematic review was carried out and discussed by an expert panel, leading to a consensus statement on their use. RESULTS: Forty-four studies reporting on the use of 17 different screening tools in older cancer patients were identified. The tools most studied in older cancer patients are G8, Flemish version of the Triage Risk Screening Tool (fTRST) and Vulnerable Elders Survey-13 (VES-13). Across all studies, the highest sensitivity was observed for: G8, fTRST, Oncogeriatric screen, Study of Osteoporotic Fractures, Eastern Cooperative Oncology Group-Performance Status, Senior Adult Oncology Program (SAOP) 2 screening and Gerhematolim. In 11 direct comparisons for detecting problems on a full GA, the G8 was more or equally sensitive than other instruments in all six comparisons, whereas results were mixed for the VES-13 in seven comparisons. In addition, different tools have demonstrated associations with outcome measures, including G8 and VES-13. CONCLUSIONS: Screening tools do not replace GA but are recommended in a busy practice in order to identify those patients in need of full GA. If abnormal, screening should be followed by GA and guided multidisciplinary interventions. Several tools are available with different performance for various parameters (including sensitivity for addressing the need for further GA). Further research should focus on the ability of screening tools to build clinical pathways and to predict different outcome parameters.

Relevance of a systematic geriatric screening and assessment in older patients with cancer: results of a prospective multicentric study.

BACKGROUND: To evaluate the large-scale feasibility and usefulness of geriatric screening and assessment in clinical oncology practice by assessing the impact on the detection of unknown geriatric problems, geriatric interventions and treatment decisions. PATIENTS AND METHODS: Eligible patients who had a malignant tumour were ≥70 years old and treatment decision had to be made. Patients were screened using G8; if abnormal (score ≤14/17) followed by Comprehensive Geriatric Assessment (CGA). The assessment results were communicated to the treating physician using a predefined questionnaire to assess the topics mentioned above. RESULTS: One thousand nine hundred and sixty-seven patients were included in 10 hospitals. Of these patients, 70.7% had an abnormal G8 score warranting a CGA. Physicians were aware of the assessment results at the time of treatment decision in two-thirds of the patients (n = 1115; 61.3%). The assessment detected unknown geriatric problems in 51.2% of patients. When the physician was aware of the assessment results at the time of decision making, geriatric interventions were planned in 286 patients (25.7%) and the treatment decision was influenced in 282 patients (25.3%). CONCLUSION: Geriatric screening and assessment in older patients with cancer is feasible at large scale and has a significant impact on the detection of unknown geriatric problems, leading to geriatric interventions and adapted treatment.

Advanced oesophago-gastric adenocarcinoma in older patients in the era of immunotherapy. A review of the literature.

Gastric (G) and gastro-esophageal junction (GEJ) adenocarcinomas are of the most common and deadly cancers worldwide and affect mainly patients over 70 years at diagnosis. Older age has been associated in gastric cancers with distal tumour location, well-differentiated adenocarcinoma and microsatellite instability and is not identified itself as an independent prognostic factor. As immune checkpoint inhibitors recently changed the landmark of advanced G and GEJ adenocarcinomas treatment, we decided to perform a literature review to define the evidence-level of clinical data in older patients. This work underlined the lasting low -inclusion rate of older patients and -implementation rate of frailty screening tools in clinical trials in G/GEJ carcinomas. In the first-line metastatic setting, two prospective randomized phase III studies have specifically assessed the efficacy of chemotherapy in older patients with HER2-negative gastric cancers, demonstrating the feasibility of reduced dose oxaliplatin-based chemotherapy regimen in this population. Only few data are available in HER2-positive tumors, or in the second-line setting. Furthermore, no specific trial with immune checkpoint inhibitors was performed in older frail patients whereas their benefit/adverse events ratio make them attractive candidates in this patient's population. We conclude that older fit patients can be treated in the same way as younger ones and included in clinical trials. Improving the outcome of older frail patients should be the oncology community next focus by implementing targeted interventions before initiating cancer therapy and designing specific clinical trials. Frailty screening tools and geriatric data collection have to be implemented in routine-practice and clinical trials.

[Comorbid anxiety disorders and alcohol-related disorders in a population of bipolar I disorder: investigation in a Flemish population]. / Comorbide angststoornissen en stoornissen in alcoholgebruik bij bipolaire I-stoornis; onderzoek in een Vlaamse populatie.

BACKGROUND: Bipolar I disorder (bp i) is a very debilitating psychiatric disorder which is frequently associated with comorbid psychiatric and somatic disorders. Many studies in other countries show strongly elevated prevalences of anxiety disorders and alcohol-related disorders in the bp i population, but so far no data on this topic are available with regard to the Flemish population. AIM: To determine the prevalence of anxiety disorders and alcohol-related disorders in a Flemish population of bp i outpatients in remission and to find out whether comorbidity of these disorders is linked to the onset of the disorder at a younger age. METHOD: Sixty-nine bp i patients in remission were given structured interviews at home and the results were compared with the Belgian prevalence reported in the European Study of the Epidemiology of Mental Disorders (esemed) project. results Both the prevalence of the alcohol-related disorders (15 of 69 patients or 21.7%) and the prevalence of anxiety disorders (17 patients or 24.6%) were elevated compared to the general population (8.1 and 13.2% respectively). Among the anxiety disorders the prevalence was elevated for panic disorder, social phobia and post-traumatic stress disorder. No significant association was found between the comorbidity and the patient's age at the onset of the illness. CONCLUSION: The prevalence of anxiety disorders and alcohol-related disorders in an outpatient population of Flemish patients with bp i in remission is elevated.

The effect of adjuvant chemotherapy on symptom burden and quality of life over time; a preliminary prospective observational study using individual data of patients aged ≥70 with early stage invasive breast cancer.

OBJECTIVES: We aim to assess short and long term effects of chemotherapy on patient-reported quality of life (QOL) and patient versus clinician symptom reporting in older patients with breast cancer adjusted for tumour and aging parameters. MATERIAL AND METHODS: In this prospective, multicentre, non-interventional, observational study, women aged ≥70years were enrolled after surgery and assigned to a TC chemotherapy (docetaxel and cyclophosphamide) group or a control group depending on their planned adjuvant treatment. Longitudinal multivariate models were used to assess the statistical and minimal clinically important difference (MCID) in the impact of TC chemotherapy over time on QOL and symptom burden adjusted for baseline aging and tumour parameters. Statistical significance was set at 5% and MCID at 10 points. RESULTS: In total, 57 patients were enrolled in the chemotherapy and 52 patients in the control group. Within the chemotherapy group, clinical deterioration was reported at 3months for Fatigue (17.73), Dyspnoea (17.05), Diarrhoea (12.06) and Appetite Loss (17.05) scores (all p<0.001). However, the scores had returned to baseline (or even better for Role Functioning) at year 1. No clinical deterioration was reported in the control group. Symptom scores as reported by patients were significantly (p<0.05) higher than those reported by the clinicians, even more so for Fatigue, Dyspnoea, and Pain. CONCLUSION: Our results show that symptom burden and diminished QOL in an older breast cancer population receiving adjuvant TC chemotherapy are short-lived and disappear after a while with no long-term differences compared to a similar population not receiving chemotherapy.

A Belgian Survey on Geriatric Assessment in Oncology Focusing on Large-Scale Implementation and Related Barriers and Facilitators.

OBJECTIVES: The aim of this study is to describe a large-scale, Belgian implementation project about geriatric assessment (=GA) in daily oncology practice and to identify barriers and facilitators for implementing GA in this setting. Design / setting / participants: The principal investigator of every participating hospital (n=22) was invited to complete a newly developed questionnaire with closed- and open-ended questions. The closed-ended questions surveyed how GA was implemented. The open-ended questions identified barriers and facilitators for the implementation of GA in daily oncology practice. Descriptive statistics and conventional content analysis were performed as appropriate. RESULTS: Qualifying criteria (e.g. disease status and cancer type) for GA varied substantially between hospitals. Thirteen hospitals (59.1%) succeeded to screen more than half of eligible patients. Most hospitals reported that GA data and follow-up data had been collected in almost all screened patients. Implementing geriatric recommendations and formulating new geriatric recommendations at the time of follow-up are important opportunities for improvement. The majority of identified barriers were organizational, with high workload, lack of time or financial/staffing problems as most cited. The most cited facilitators were all related to collaboration. CONCLUSION: Interventions to improve the implementation of GA in older patients with cancer need to address a wide range of factors, with organization and collaboration as key elements. All stakeholders, seeking to improve the implementation of GA in older patients with cancer, should consider and address the identified barriers and facilitators.
