The EORTC QLU-C10D is a valid cancer-specific preference-based measure for cost-utility and health technology assessment in the Netherlands.

BACKGROUND: Cost-utility analysis typically relies on preference-based measures (PBMs). While generic PBMs are widely used, disease-specific PBMs can capture aspects relevant for certain patient populations. Here the EORTC QLU-C10D, a cancer-specific PBM based on the QLQ-C30, is validated using Dutch trial data with the EQ-5D-3L as a generic comparator measure. METHODS: We retrospectively analysed data from four Dutch randomised controlled trials (RCTs) comprising the EORTC QLQ-C30 and the EQ-5D-3L. Respective Dutch value sets were applied. Correlations between the instruments were calculated for domains and index scores. Bland-Altman plots and intra-class correlations (ICC) displayed agreement between the measures. Independent and paired t-tests, effect sizes and relative validity indices were used to determine the instruments' performance in detecting clinically known-group differences and health changes over time. RESULTS: We analysed data from 602 cancer patients from four different trials. In overall, the EORTC QLU-C10D showed good relative validity with the EQ-5D-3L as a comparator (correlations of index scores r = 0.53-0.75, ICCs 0.686-0.808, conceptually similar domains showed higher correlations than dissimilar domains). Most importantly, it detected 63% of expected clinical group differences and 50% of changes over time in patients undergoing treatment. Both instruments showed poor performance in survivors. Detection rate and measurement efficiency were clearly higher for the QLU-C10D than for the EQ-5D-3L. CONCLUSIONS: The Dutch EORTC QLU-C10D showed good comparative validity in patients undergoing treatment. Our results underline the benefit that can be achieved by using a cancer-specific PBM for generating health utilities for cancer patients from a measurement perspective.

Longitudinal trajectories of depression and quality of life in a cohort of cancer survivors and individuals without cancer in Europe.

BACKGROUND: The long-term effects of cancer on psychological symptoms and quality of life (QoL) have been widely reported, but they were seldom examined over time compared to the general population. AIMS: To investigate trajectories of depression and QoL over time among cancer survivors compared to individuals without cancer throughout Europe and identify associated factors. METHODS: Data from five waves of the Survey of Health, Ageing and Retirement in Europe study were used. The study sample featured 1066 cancer survivors and 9655 individuals without cancer from 13 European countries. Group-based trajectory modeling was used to identify depression and QoL trajectories, and a linear mixed-effects model was used to characterize their correlates. RESULTS: Four depression trajectories-stable low, stable high, increasing, and decreasing-and four QoL trajectories were identified. All QoL trajectories were stable over time, but differed in their levels: low, low-medium, medium-high, and high. Depression and QoL trajectories were similar between cancer survivors and individuals without cancer. However, significantly more cancer survivors had high-depression and low-QoL trajectories. Further, better perceived health, activities of daily living, physical activity, and income adequacy levels were significantly associated with changes in depression and QoL levels over time. CONCLUSIONS: Although depression and QoL trajectories did not differ between cancer survivors and individuals without cancer, more cancer survivors were characterized by high-depression and low-QoL life trajectories. IMPLICATIONS FOR CANCER SURVIVORS: Providers should be aware and screen for cancer survivors with elevated depression and low QoL, and promote relevant psychosocial interventions. Modifiable factors associated with depression and QoL can be targets for cancer survivors' long-term care plans.

The course of swallowing problems in the first 2 years after diagnosis of head and neck cancer.

INTRODUCTION: Head and neck cancer (HNC) and its treatment often negatively impact swallowing function. The aim was to investigate the course of patient-reported swallowing problems from diagnosis to 3, 6, 12, and 24 months after treatment, in relation to demographic, clinical, and lifestyle factors. METHODS: Data were used of the Netherlands Quality of Life and Biomedical Cohort Study in head and neck cancer research (NET-QUBIC). The primary outcome measures were the subscales of the Swallowing Quality of Life Questionnaire (SWAL-QOL). Linear mixed-effects models (LMM) were conducted to investigate changes over time and associations with patient, clinical, and lifestyle parameters as assessed at baseline. RESULTS: Data were available of 603 patients. There was a significant change over time on all subscales. Before treatment, 53% of patients reported swallowing problems. This number increased to 70% at M3 and decreased to 59% at M6, 50% at M12, and 48% at M24. Swallowing problems (i.e., longer eating duration) were more pronounced in the case of female, current smoking, weight loss prior to treatment, and stage III or IV tumor, and were more prevalent at 3 to 6 months after treatment. Especially patients with an oropharynx and oral cavity tumor, and patients receiving (C)RT following surgery or CRT only showed a longer eating duration after treatment, which did not return to baseline levels. CONCLUSION: Half of the patients with HNC report swallowing problems before treatment. Eating duration was associated with sex, smoking, weight loss, tumor site and stage, and treatment modality, and was more pronounced 3 to 6 months after treatment.

Recommended patient information sheet on the impact of haematopoietic cell transplantation on sexual functioning and sexuality.

Sexual concerns are common after haematopoietic cell transplantation (HCT). Exposure to total body irradiation (TBI), alkylating agent and graft versus host disease (GvHD) can all affect sexual function, leading to problems in sexual desire, arousal and the orgasm phase of the sexual response cycle. In high-risk haematological malignancies, such as acute leukaemia and myelodysplastic syndromes, HCT often offers the highest chance for long-term survival. In addition, these haematological diseases and HCT can have an impact on body image, self-esteem, (sexual) relationship and psychosocial factors, all of which are able to affect sexuality and sexual function. Five years post HCT, 80% of the female survivors and 46% of the male survivors report sexual dysfunction. It has been shown that these patients cope better after having discussed sexual health. While healthcare providers (HCPs) have the responsibility to address sexual issues, it has been demonstrated that 48%-82% HCT recipients reported not having discussed sexual issues with their HCPs and that only one-third of the HCPs routinely discussed sexual issues with their patients. HCPs describe a lack of knowledge and being uncomfortable with the topic as the most important reasons for not addressing sexual functioning. Even so, it would help >90% HCPs if the patient initiated discussing sexual issues. However, to empower patients addressing sexual issues, adequate comprehensive patient information is needed. In an effort to better meet the patients' need, a patient information sheet: 'Information for patients undergoing Hematopoietic Cell Transplantation: the impact of the disease and treatment on sexual function and sexuality', has been created. In this review, we describe what is known about the impact of HCT on sexual function and briefly the management of sexual problems.
