The personal impact of living with a myeloproliferative neoplasm

OBJECTIVE

The aim of this study is to gain insight into the physical, psychological and social impact of having a myeloproliferative neoplasm (MPN), a rare type of cancer with an often chronic course.

METHODS

An online survey was conducted among 455 Dutch MPN patients (62.7% female, age M 63) to explore the impact of the disease by measuring the MPN symptom burden (MPN-SAF TSS) and quality of life (QoL) (EORTC QLQ-C30) and its subscales within a hierarchical QoL model. We examined differences in MPN symptom burden and QoL in relation to sociodemographic and disease-related factors. Hierarchical regression analysis was used to explain variances in QoL.

RESULTS

Most patients (97%) experienced MPN-related health complaints, with a significantly higher MPN symptom burden in women (M 31.50) compared to men (M 24.10). Regarding to fatigue and cognitive functioning MPN patients suffered more compared to a reference group of other cancers. MPN subtype or type of treatment did not show significant differences in MPN symptom burden or QoL. However, experiencing side effects, complications or comorbidities significantly negatively affected MPN symptom burden and QoL. 48.8% of patients reported that MPN affected their ability to work. The explained variance in overall QoL was 58%, most importantly by disease progression, comorbidities, MPN symptom burden and role, emotional and social functioning.

CONCLUSION

This study revealed that having an MPN has a negative impact on several domains of QoL. Symptom assessment and support should be included in the healthcare management of MPN patients.

Psychometric properties of the Dutch extended Cancer Survivors' Unmet Needs measure (CaSUN-NL)

Information and support needs increase emotional distress and can impede cancer survivors’ adjustment. To investigate the information and support needs of Dutch cancer survivors, the Cancer Survivors’ Unmet Needs measure (CaSUN) was translated into Dutch and applied in two Dutch studies with cancer survivors (N = 255; N = 467). The CaSUN‐NL entailed the original five CaSUN scales, extended with respectively a returning to work and lifestyle scale. This study aimed to determine the psychometric properties of the CaSUN‐NL. To assess validity, a maximum likelihood factor analysis was employed. Construct validity was analysed using Pearson's and Spearman's correlation coefficients. To assess reliability, test–retest (Kappa coefficient) and internal consistency (Cronbach's alpha) values were determined. Factor analysis revealed the original five factors. Test–retest reliability was low (r ≤ .15, 93% retest response). Internal consistency values were high (Cronbach's alpha = 0.92–0.94), except for lifestyle. Significant correlations were found between total number of unmet needs with anxiety (r = .55), depression (r = .49), negative adjustment (r = .50), quality of life (r = −.52) and age (r = −.24). The CaSUN‐NL is valid and reliable to investigate the unmet information and support needs of Dutch cancer survivors.
