The survival disparity between children and adolescents and young adults (AYAs) with Ewing sarcoma in the Netherlands did not change since the 1990s despite improved survival: A population-based study.

Background: Adolescents and young adults (AYAs) with Ewing sarcoma have a worse prognosis than children. Population-based survival evaluations stratifying findings by important clinical factors are, however, limited. This Dutch population study comprehensively compared survival of children and AYAs with Ewing sarcoma over three decades considering diagnostic period, tissue of origin, tumor site, and disease stage.

Pre-treatment fertility preservation and post-treatment reproduction in long-term survivors of adolescent and young adult (AYA) cancer.

Purpose: To describe recall of fertility-related consultations and cryopreservation and to examine reproductive goals and reproduction post-treatment in long-term survivors of adolescent and young adult (AYA) (age, 18-39 years) cancer.

Methods: This study included n = 1457 male and n = 2112 female long-term survivors (M = 43-45 years; 5-22 years from diagnosis) who provided self-report. Clinical data were supplied by the Netherlands Cancer Registry.

Sexual quality of life of adolescents and young adult breast cancer survivors.

Background: With increasing survival rates of adolescents and young adults (AYAs) with breast cancer, health-related quality of life (HRQoL) becomes more important. An important aspect of HRQoL is sexual QoL. This study examined long-term sexual QoL of AYA breast cancer survivors, compared sexual QoL scores with that of other AYA cancer survivors, and identified factors associated with long-term sexual QoL of AYA breast cancer survivors.

Adherence to the World Cancer Research Fund/American Institute for Cancer Research recommendations for cancer prevention in adolescent and young adult (AYA) cancer survivors: results from the SURVAYA study.

Purpose: For adolescent and young adult (AYA) cancer survivors with a good prognosis, having a healthy lifestyle prevents morbidity and mortality after treatment. The aim of this study was to investigate the prevalence of (un)healthy lifestyle behaviors and related determinants in AYA cancer survivors.

Methods: A population-based, cross-sectional study was performed among long-term (5-20 years) AYA cancer survivors (18-39 years old at diagnosis) registered within the Netherlands Cancer Registry.

Exploring the interconnectedness between health-related quality of life factors among long-term adolescent and young adult cancer survivors (AYAs): a network analysis.

Purpose: Adolescent and young adult cancer survivors (AYAs) are at increased risk of long-term and late effects, and experience unmet needs, impacting their health-related quality of life (HRQoL). In order to provide and optimize supportive care and targeted interventions for this unique population, it is important to study HRQoL factors' interconnectedness on a population level. Therefore, this network analysis was performed with the aim to explore the interconnectedness between HRQoL factors, in the analysis described as nodes, among long-term AYAs.

Patient-Reported Outcomes of Accelerated Aging: A Novel Approach to Investigate Second Cancer Risk in Adolescent and Young Adult (18-39 Years) Cancer Survivors.

Background: Adolescent and young adult cancer survivors (AYAs, aged 18-39 years at first diagnosis) have a higher second cancer risk. Accelerated aging is hypothesized as underlying mechanism and has been described clinically by 6 indicators; fatigue, low quality of sleep, low mood, lack of motivation, subjective memory complaints, and poor exercise tolerance. Using patient-reported outcomes, we aimed to identify clusters of accelerated aging among AYA cancer survivors and to investigate their association with second cancer development.

Health-related quality of life of Adolescent and Young Adult Cancer Survivors before and during the COVID-19 pandemic: longitudinal improvements on social functioning and fatigue.

The health-related quality of life (HRQoL) among long-term Adolescent and Young Adult Cancer Survivors (AYACS) and an age- and sex-matched normative population was examined. Although the HRQoL of AYACS was worse compared to the normative population before and during the COVID-19 pandemic, the scores of AYACS improved over time in contrast to the normative population. Presumably, AYACS are used to adjusting their lives to stressful life events.

Measuring Tumour Imatinib Concentrations in Gastrointestinal Stromal Tumours: Relevant or Redundant?

Imatinib plasma trough concentrations are associated with efficacy for patients treated for advanced or metastatic KIT-positive gastrointestinal stromal tumours (GISTs). This relationship has not been studied for patients treated in the neoadjuvant setting, let alone its correlation with tumour drug concentrations. In this exploratory study we aimed to determine the correlation between plasma and tumour imatinib concentrations in the neoadjuvant setting, investigate tumour imatinib distribution patterns within GISTs, and analyse its correlation with pathological response.

Learning from long-term adolescent and young adult (AYA) cancer survivors regarding their age-specific care needs to improve current AYA care programs.

Background: Despite growing (inter)national awareness and appreciation, age-specific care is still not always self-evident and accepted as standard of care for adolescent and young adult (AYA) cancer patients. It is unknown whether long-term AYA cancer survivors have missed age-specific care, and if so, which survivors missed it and regarding which topics.

Methods: The Netherlands Cancer Registry (NCR) identified all long-term AYA cancer survivors (aged 18-39 years at initial cancer diagnosis, 5-20 years past diagnosis) in the Netherlands, who were invited to participate in a population-based, observational, cross-sectional questionnaire study (SURVAYA study), including questions on care needs.

Genome-wide analyses of platinum-induced ototoxicity in childhood cancer patients: Results of GO-CAT and United Kingdom MAGIC consortia.

Hearing loss (ototoxicity) is a major adverse effect of cisplatin and carboplatin chemotherapy. The aim of this study is to identify novel genetic variants that play a role in platinum-induced ototoxicity. Therefore, a genome-wide association study was performed in the Genetics of Childhood Cancer Treatment (GO-CAT) cohort (n = 261) and the United Kingdom Molecular Genetics of Adverse Drug Reactions in Children Study (United Kingdom MAGIC) cohort (n = 248).

A Negative Body Image among Adolescent and Young Adult (AYA) Cancer Survivors: Results from the Population-Based SURVAYA Study.

Adolescent and young adult (AYA) cancer survivors (18-39 years at diagnosis) often experience negative body changes such as scars, amputation, and disfigurement. Understanding which factors influence body image among AYA survivors can improve age-specific care in the future. Therefore, we aim to examine the prevalence, and association of a negative body image with sociodemographic, clinical, and psychosocial factors, among AYA cancer survivors (5-20 years after diagnosis).

Quality of integrated female oncofertility care is suboptimal: A patient-reported measurement.

Background: Clinical practice guidelines recommend to inform female cancer patients about their infertility risks due to cancer treatment. Unfortunately, it seems that guideline adherence is suboptimal. In order to improve quality of integrated female oncofertility care, a systematic assessment of current practice is necessary.

AYAs' online information and eHealth needs: A comparison with healthcare professionals' perceptions.

Background: Adolescents and young adults (AYAs) diagnosed with cancer fulfill their cancer-related information needs often via the Internet. Healthcare professionals (HCPs) have a crucial role in guiding patients in finding appropriate online information and eHealth sources, a role that is often overlooked. Misperceptions of AYAs' needs by HCPs may lead to suboptimal guidance.

Pleuropulmonary blastoma (PPB) and other DICER1-associated high-grade malignancies are morphologically, genetically and epigenetically related - A comparative study of 4 PPBs and 6 sarcomas.

DICER1-related tumors occur hereditary or sporadically, with high-grade malignancies sharing clinicopathological and (epi)genetic features. We compared 4 pleuropulmonary blastomas (PPBs) and 6 sarcomas by mutation analysis, whole transcriptome sequencing and methylation profiling. 9/10 patients were female.

Differences in Internet Use and eHealth Needs of Adolescent and Young Adult Versus Older Cancer Patients; Results from the PROFILES Registry.

Background: Our aim was to evaluate differences in cancer-related internet patterns between AYAs (adolescents and young adults; 18-39 years at time of diagnosis) and older adult cancer patients (40+ years).

Methods: Cross-sectional surveys were distributed among AYA and older adult cancer patients regarding cancer-related internet use and eHealth needs.

Results: 299 AYAs (mean age 31.

Pulsed Laser Deposition of CsAgBiBr: from Mechanochemically Synthesized Powders to Dry, Single-Step Deposition.

CsAgBiBr has been proposed as a promising lead-free and stable double perovskite alternative to hybrid and lead-based perovskites. However, the low solubility of precursors during wet synthesis, or the distinct volatility of components during evaporation, results in complex multistep synthesis approaches, hampering the widespread employment of CsAgBiBr films. Here, we present pulsed laser deposition of CsAgBiBr films as a dry, single-step and single-source deposition approach for high-quality film formation.

The heterogeneity of Epithelioid Hemangioendothelioma (EHE): A case series and review of the literature with emphasis on treatment options.

Epithelioid hemangioendothelioma (EHE) is an extremely rare vascular sarcoma with a very heterogeneous presentation and prognosis. We here present five cases of EHE emphasizing diversity in presentation, treatment, and prognosis. Furthermore, we present a review of the literature on EHE treatment options.

Evidence from South Africa for a protracted end-Permian extinction on land.

Earth's largest biotic crisis occurred during the Permo-Triassic Transition (PTT). On land, this event witnessed a turnover from synapsid- to archosauromorph-dominated assemblages and a restructuring of terrestrial ecosystems. However, understanding extinction patterns has been limited by a lack of high-precision fossil occurrence data to resolve events on submillion-year timescales.

The route to diagnosis of sarcoma patients: Results from an interview study in the Netherlands and the United Kingdom.

Introduction: Sarcomas are rare tumours. Early diagnosis is challenging, but important for local control and potentially survival and quality of life(QoL). We investigated (1)the route to diagnosis (RtD) experienced by sarcoma patients, including factors contributing to the length of the RtD from patients' perspective; (2)the impact of the RtD on QoL and care satisfaction; and (3)differences in aims 1-2 between English and Dutch patients.
