Summary Background With the growing number of cancer survivors worldwide the need for high quality cancer rehabilitation after primary treatment is steadily increasing. The aim of the present study was to investigate change of psychological distress and health-related quality of life (HRQOL) during multidisciplinary inpatient cancer rehabilitation in a large sample of cancer survivors suffering from different cancer entities. Methods We analyzed data from routine HRQOL and distress monitoring at a cancer inpatient rehabilitation center. Cancer survivors completed the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core-30 (EORTC QLQ-C30) and the Hospital Anxiety and Depression Scale (HADS) before and after multidisciplinary rehabilitation treatment. Changes of patients’ functioning and symptoms were analyzed using repeated measures analysis of variance (ANOVA) and effect sizes (Cohens’ d). Patients’ pretreatment and posttreatment scores were compared to reference data from the German general population. Results A total of 939 patients (mean age 58.6 years, SD 11.9 years; 59.9% women) who attended rehabilitation from January 2014 to September 2015 were included in the analysis. We found clinically meaningful improvement in almost all domains of the EORTC QLQ-C30 as well as in anxiety and depression (HADS). The largest improvements were found for the QLQ-C30 subscales emotional functioning (d = 0.78), fatigue (d = 0.65), and social functioning (d = 0.56). Conclusions We found clinically meaningful improvements of patients’ HRQOL, anxiety and depression during an oncological inpatient rehabilitation treatment. Our results warrant further prospective controlled studies to evaluate the long-term effectiveness of inpatient rehabilitation.

Objective: We investigated cancer survivors’ health-related quality of life (HRQOL), specific deficiencies related to underlying disease or treatment, and benefits of rehabilitation in a large variety of cancer entities. Patients and methods: Electronic patient-reported outcomes were performed as clinical routine procedures. Cancer survivors underwent a 3-week multidisciplinary inpatient rehabilitation. Twenty-one different cancer entities were analyzed separately before (T0) and by the end (T1) of rehabilitation. HRQOL, symptoms, and functions were assessed with EORTC-QLQ-C30 questionnaire, psychological distress with Hospital Anxiety and Depression Scale (HADS). Results: Four thousand four hundred one of 5912 rehabilitants were evaluable, having completed both questionnaires at T0 and T1. All function mean scores and HRQOL were lower than in Austrian normal population, while levels of anxiety, depression, and all symptom scores were higher. HRQOL was particularly low in lung, liver, and bladder cancer patients. Maximum anxiety levels were observed in patients with breast and thyroid cancer patients, the highest levels of depression in liver and brain cancer patients. Fatigue was severe in patients with lung, liver, esophageal, bladder cancer, and myeloma patients. Mean scores were also high for pain and insomnia. In the group of all rehabilitants, a highly significant improvement of global HRQOL, anxiety, depression, and all function and symptom scores was observed at T1 (p < 0.001). We noted significant improvement of HRQOL, anxiety, depression, fatigue, emotional, social, role, and physical functions in each cancer entity with medium to large effect sizes. Other recorded symptoms were reduced in the majority of cancers. Conclusion: Rehabilitation effectively improves psychological distress and HRQOL as a part of treatment for various cancers.

Background: Patient-reported outcomes are considered the gold standard for assessing subjective health status in oncology patients. Electronic assessment of patient-reported outcomes (ePRO) has become increasingly popular in recent years in both clinical trials and practice. However, there is limited evidence on how well older patients with cancer can complete ePRO assessments. Objective: We aimed to investigate how well adult patients with cancer of different age ranges could complete ePRO assessments at home and in a treatment facility and to identify factors associated with the ability to complete questionnaires electronically. Methods: This retrospective longitudinal single-center study involved survivors of cancer who participated in inpatient rehabilitation. Patients completed ePRO assessments before rehabilitation at home (T1) and after rehabilitation at the facility (T2). We analyzed the rate of patients who could complete the ePRO assessment at T1 and T2, the proportion of patients who required assistance, and the time it took patients to complete standardized questionnaires. Multivariate logistic regression analyses were conducted to identify predictors of ePRO completion rate and the need for assistance. Results: Between 2017 and 2022, a total of 5571 patients were included in this study. Patients had a mean age of 60.3 (SD 12.2) years (range 18 to 93 years), and 1135 (20.3%) of them were classified as geriatric patients (>70 years). While more than 90% (5060/5571) of all patients completed the ePRO assessment, fewer patients in the age group of >70 years (924/1135, 81.4% at T1 vs 963/1135, 84.8% at T2) completed the assessment. Approximately 19% (1056/5571) of patients reported a need for assistance with the ePRO assessment at home, compared to 6.8% (304/4483) at the institution. Patients older than 70 years had a significantly higher need for assistance than those in younger age groups. Moreover, a gender difference was observed, with older women reporting a higher need for assistance than men (71-80 years: women requiring assistance 215/482, 44.6% vs men 96/350, 27.4%; P<.001 and >80 years: women 102/141, 72.3% vs men 57/112, 50.9%; P<.001). On average, patients needed 4.9 (SD 3.20) minutes to remotely complete a 30-item questionnaire (European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire) and patients in the older age groups took significantly longer compared to younger age groups. Lower age and higher physical functioning were the clearest predictors for both the ePRO completion rate and the need for assistance in the multivariate regression analysis. Conclusions: This study’s results indicate that ePRO assessment is feasible in older individuals with cancer, but older patients may require assistance (eg, from relatives) to complete home-based assessments. It may be more feasible to conduct assessments in-house in this population. Additionally, it is crucial to carefully consider which resources are necessary and available to support patients in using ePRO devices.

Rehabilitation is a key element in improving health-related quality of life (HRQOL) for pediatric cancer survivors. The aim of this study was to present data from a multidisciplinary inpatient rehabilitation treatment. Children took part in a four-week multidisciplinary family-oriented inpatient rehabilitation. A total of 236 children (>5–21 years) and 478 parents routinely completed electronic patient-reported outcomes (ePROs), performance-based assessments, and clinician-rated assessments before (T1) and at the end (T2) of rehabilitation. HRQOL was assessed with the PedsQL generic core and PedsQL cancer module. Data were analyzed using repeated measures analysis of variance (ANOVA). Statistically significant improvements with medium to large effect sizes were observed for most HRQOL scales (η2 = 0.09–0.31), as well as performance-based and clinician-rated assessments for physical activity and functional status (η2 > 0.28). Agreement between children’s PROs and parents’ proxy ratings was lower before (rICC = 0.72) than after (rICC = 0.86) rehabilitation. While the concordance between children and parents’ assessment of changes during rehab was low to moderate (r = 0.19–0.59), the use of the performance score led to substantially increased scores (r = 0.29–0.68). The results of this naturalistic observational study thus highlight the benefits of multidisciplinary pediatric inpatient rehabilitation for childhood cancer survivors. The use of the performance score is recommended in this field.

Many patients with head-and-neck cancer (HNC) suffer from speech or swallowing disorders. We investigated the impact of dysphagia on health-related quality of life (HRQOL), functioning, and distress in HNC survivors, and whether cancer rehabilitation can alleviate these conditions. Before admission (T0) and at discharge (T1) of three-week inpatient cancer rehabilitation, patient-reported outcomes were collected. HRQOL, symptoms, functioning, and psychological distress were assessed with EORTC QLQ-C30 and Hospital Anxiety and Depression Scale (HADS) questionnaires. Of 63 HNC patients, 22 had dysphagia, 23 needed no speech therapy (Control-1), and 18 needed speech therapy, but showed no symptoms of dysphagia (Control-2). Before rehabilitation, HRQOL, physical, social, and emotional functioning were significantly lower in dysphagia patients than in controls. Dysphagia patients reported more severe general symptoms including fatigue, pain, sleep disturbances, nausea/vomiting, diarrhea, and financial worries. Furthermore, the emotional and social functioning of Control-2 was significantly worse than Control-1. For all HNC patients, social, emotional, and role functioning, fatigue, nausea/vomiting, insomnia, and appetite loss significantly improved at T1. Improvements in HRQOL were most noticeable in dysphagia patients. Psychooncological counseling reduced depression in dysphagia and Control-2 patients to levels seen in the general population. In conclusion, dysphagia patients suffer severely from impaired functioning and systemic symptoms but benefit substantially from rehabilitation.
