Emotion Regulation Flexibility and Electronic Patient-Reported Outcomes: A Framework for Understanding Symptoms and Affect Dynamics in Pediatric Psycho-Oncology. Cancers (Basel) 2022; 14:cancers14163874. [PMID: 36010870 PMCID: PMC9405711 DOI: 10.3390/cancers14163874] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2022] [Revised: 08/03/2022] [Accepted: 08/08/2022] [Indexed: 11/25/2022] Open
Abstract
Simple Summary The individual’s ability to conceive and regulate the broad spectrum of their human emotions is closely linked to their mental health. The implications of a serious disease such as cancer represent an extraordinary burden to these internal coping mechanisms, especially in the case of young patients. Regarding their well-being and support, it is therefore of particular interest for caregivers to be able to follow the dynamics of the patient’s emotional world and perceptions. Technical progress enables new possibilities for data collection through tools for digital patient self-reports while simultaneously creating new challenges. Within the scope of this article, we provide an overview of the literature on this topic, outlining the current strengths and weaknesses and possible perspectives on digital aids, especially in terms of capturing the flexibility, fluctuations and early detection of symptom changes. Abstract Emotion dysregulation is regarded as a driving mechanism for the development of mental health problems and psychopathology. The role of emotion regulation (ER) in the management of cancer distress and quality of life (QoL) has recently been recognized in psycho-oncology. The latest technological advances afford ways to assess ER, affective experiences and QoL in child, adolescent and young adult (CAYA) cancer patients through electronic patient-reported outcomes (ePRO) in their daily environment in real-time. Such tools facilitate ways to study the dynamics of affect and the flexibility of ER. However, technological advancement is not risk-free. We critically review the literature on ePRO in cancer existing models of ER in pediatric psycho-oncology and analyze strength, weaknesses, opportunities and threats of ePRO with a focus on CAYA cancer research and care. Supported by personal study-based experiences, this narrative review serves as a foundation to propose a novel methodological and metatheoretical framework based on: (a) an extended notion of ER, which includes its dynamic, adaptive and flexible nature and focuses on processes and conditions rather than fixed categorical strategies; (b) ePRO as a means to measure emotion regulation flexibility and affect dynamics; (c) identifying early warning signals for symptom change via ePRO and building forecasting models using dynamical systems theory.

Abstract
OBJECTIVE This study aimed to compare a new vitrification protocol with reduced cryoprotectant exposure to the slow freezing method in the cryopreservation of prepubertal rat testicular tissue. METHODS Five sexually immature male Wistar rats were submitted to bilateral orchiectomy. Tissue samples from each testicle were fragmented into small pieces and randomly assigned to three groups: Group A, fresh tissue (control); Group B, slow programmable freezing (SPF); and Group C (vitrification). Frozen/thawed, vitrified/warmed, and fresh testicular tissue were histologically compared. A pathologist blinded to the procedures assessed the morphology (cell differentiation, nuclei, and epithelium) of 10 seminiferous tubules from each testicle (100 tubules per Group). RESULTS Sertoli and spermatogonial stem cells were easily differentiated, and the nucleoli were easily viewed in the tubules assessed in all three groups. Small alterations in tissue architecture were observed in the control group as a result of tissue handling. Moderate alterations of the epithelium with the formation of small gaps and cell detachment from the basement membrane were observed in 28% of the frozen and 9% of the vitrified tubules. Condensed nuclei involving a small proportion of cells were observed in six and three tubules of the frozen and vitrified group, respectively. Despite the alterations, 97% of the frozen and 99% of the vitrified tubules were considered well preserved. CONCLUSIONS The findings indicate that the vitrification protocol tested in this study adequately preserved the morphological integrity of prepubertal testicular tissue in a rat model. Further studies are required to confirm testicular tissue function after grafting.

Abstract
Testicles can be damaged by a variety of physical and chemical agents, ranging from trauma suffered in accidents or athletic activities, to diverse drugs or radiation used in cancer treatment. The immediate and long-term effects of these damaging agents at the testicular morphologic and functional levels are quite varied and may have significant impact on the fertility of the pediatric patient once reproductive age is reached.

Abstract
OBJECTIVE We have analysed incidence and survival trends of children and adolescents with leukaemia registered in Spanish population-based cancer registries during the period 1983-2007. METHODS Childhood and adolescent leukaemia cases were drawn from the 11 Spanish population-based cancer registries. For survival, registries with data for the period 1991-2005 and follow-up until 31-12-2010 were included. Overall incidence trends were evaluated using joinpoint analysis. Observed survival rates were estimated using Kaplan-Meier, and trends were tested using the log-rank test. RESULTS Based on 2606 cases (2274 children and 332 adolescents), the overall age-adjusted incidence rate (ASRw) of leukaemia was 47.9 cases per million child-years in children and 23.8 in adolescents. The ASRw of leukaemia increased with an annual percentage change of 9.6 % (95 % CI: 2.2-17.6) until 1990 followed by a stabilisation of rates. In adolescents, incidence did not increase. Five-year survival increased from 66 % in 1991-1995 to 76 % in 2001-2005. By age, survival was dramatically lower in infants (0) and adolescents (15-19) than in the other age groups and no improvement was observed. In both children and adolescents, differences in 5-year survival rates among major subgroups of leukaemias were significant. CONCLUSIONS The increasing incidence trends observed in childhood leukaemias during the study period were confined to the beginning of the period. Remarkable improvements in survival have been observed in Spanish children with leukaemias. However, this improvement was not observed in infants and adolescents.

Abstract
AIM For an evaluation of the progress achieved in the field of kidney cancer care in the Netherlands in the last decades, we described trends in incidence, treatment, mortality and relative survival. METHODS All adult patients newly diagnosed with kidney cancer between 1989 and 2009 (N=32,545) were selected from the Netherlands Cancer Registry. Age-standardised incidence and mortality rates were calculated. Follow-up was completed until January 2010. In order to assess trends estimated annual percentages of change (EAPC) were estimated. RESULTS The incidence of kidney cancer has been fairly stable between 1989 and 2001 with a European Standardised Rate of approximately 11 per 100,000 person years (PY). Since 2001 the incidence increased to 13 per 100,000 PY in 2009 (EAPC: 2.4%; 95%confidence interval (CI): 1.5 to 3.4%). The mortality rate decreased slightly over time, from 6.2 per 100,000 PY in 1989 to 5.6 in 2010. No changes in treatment were observed, except for the introduction of targeted therapies for stage IV disease, since 2005. The 5-year relative survival improved from 51% in 1989-1994 to 58% in 2005-2009 (EAPC: 0.9%; 95%CI 0.7 to 1.2%). Improvement in survival was especially seen in males, younger age groups and low stages. CONCLUSIONS The incidence of kidney cancer has increased slightly, and survival improved modestly, resulting in a decreasing mortality. A positive effect of the introduction of targeted therapies for metastatic kidney cancer was observed in 1-year relative survival. For progress in kidney cancer care, effective prevention strategies and new therapies remain warranted.

Abstract
BACKGROUND This study provides the latest available relative survival data for Australian childhood cancer patients. METHODS Data from the population-based Australian Paediatric Cancer Registry were used to describe relative survival outcomes using the period method for 11,903 children diagnosed with cancer between 1983 and 2006 and prevalent at any time between 1997 and 2006. RESULTS The overall relative survival was 90.4% after 1 year, 79.5% after 5 years and 74.7% after 20 years. Where information onstage at diagnosis was available (lymphomas, neuroblastoma, renal tumours and rhabdomyosarcomas), survival was significantly poorer for more-advanced stage. Survival was lower among infants compared with other children for those diagnosed with leukaemia, tumours of the central nervous system and renal tumours but higher for neuroblastoma. Recent improvements in overall childhood cancer survival over time are mainly because of improvements among leukaemia patients. CONCLUSION The high and improving survival prognosis for children diagnosed with cancer in Australia is consistent with various international estimates. However, a 5-year survival estimate of 79% still means that many children who are diagnosed with cancer will die within 5 years, whereas others have long-term health morbidities and complications associated with their treatments. It is hoped that continued developments in treatment protocols will result in further improvements in survival.

Abstract
The timeliness of survival monitoring is particularly important in a field such as transplantation medicine, where progress occurs rapidly. Period analysis, a method successfully applied for improving the timeliness of survival monitoring in population-based cancer survival analysis, could potentially be useful in the field of transplantation as well. Using data from the Collaborative Transplant Study, the authors compared the ability of traditional, cohort-based analysis methods and the period analysis method to provide timely 5-year graft and patient survival estimates for kidney, heart, and liver transplants in 6 age groups (0-17, 18-29, 30-39, 40-49, 50-59, >or=60 years) on 378 occasions between 1990-1992 and 2000-2002. Overall, period estimates provided superior predictions for the survival of most recent transplants on 344 of 378 occasions (91%); in the organ-specific analysis, this proportion ranged between 83% for heart and 100% for kidney graft survival. This evaluation provides evidence that the period analysis method can improve the timeliness of survival monitoring in solid organ transplantation. The method appears useful for providing more up-to-date long-term survival estimates than traditional methods, and its use in pertinent studies is encouraged.

Abstract
BACKGROUND Tumours of the central nervous system (CNS) account for 15-20% of all malignant childhood tumours in developed countries. Steady improvement of survival of children with CNS tumours has been reported for the past decades. However, these results, obtained by cohort analysis of survival, do not reflect the full extent of recent improvement. METHODS Using selected registries from the database of the Automated Childhood Cancer Information System (ACCIS), we calculated period survival estimates for the years 1995-99 for children diagnosed with a malignant CNS tumour. RESULTS The overall 10-year period survival estimate for the years 1995-99 was 59% for children with all CNS tumours combined, 73% for children with astrocytoma, 53% for children with ependymoma and 45% for children with primitive neuroectodermal tumours. On average, estimates derived by cohort analysis (pertaining to children diagnosed in 1985-89) were around 4% units lower. Region-specific analysis revealed that recent progress was largest in Eastern Europe, where prognosis nevertheless remained lower than in other European regions. In Northern and Southern Europe, 10-year survival remained essentially unchanged. CONCLUSION Although period survival of children with CNS tumours is higher than previously reported cohort survival, their long-term prognosis remains modest compared to other childhood malignancies.

Abstract
BACKGROUND Prognosis for most types of childhood tumours has improved during the last few decades. In this article we estimate up-to-date period survival for less common, but important childhood malignancies in Europe. METHODS Using the database of the Automated Childhood Cancer Information System we calculated period estimates of 10-year survival for the 1995-1999 period for children aged 0-14 years diagnosed during 1985-1999 with tumours of the sympathetic nervous system (NS), retinoblastoma, renal tumours, bone tumours and soft tissue sarcomas in four European regions. RESULTS Ten-year period survival for 1995-1999 was 66% in children with tumours of the sympathetic NS, 96% for retinoblastoma, 87% for renal tumours, 58% for bone tumours and 61% for soft tissue sarcomas. The higher period estimates, as compared with cohort and complete estimates indicate recent improvement in survival for tumours of the sympathetic NS and to a lesser extent for retinoblastoma and renal tumours. Region-specific period survival estimates were lowest for Eastern Europe for renal, bone and soft tissue tumours, but not for the other two tumour groups. CONCLUSION There have been further improvements in the 1990s in long-term survival of children diagnosed with several malignancies, albeit to a different extent in different European regions.

Abstract
BACKGROUND In recent decades, following the introduction of effective chemotherapy, the prognosis of children with leukaemia and lymphoma has dramatically improved, but data reflecting further possible improvement achieved in the 1990s are scarce. METHODS Using the Automated Childhood Cancer Information (ACCIS) database, we carried out a period analysis of 10-year survival for the 1995-99 period. Analyses were carried out by diagnostic groups, age-group at diagnosis, sex and four European regions. RESULTS Ten-year survival estimates for the 1995-99 period were 73% for any type of leukaemia, 78% for acute lymphoid leukaemia and 52% for acute non-lymphocytic leukaemia. The corresponding 10-year survival rates for all types of lymphomas, Hodgkin lymphoma, and non-Hodgkin lymphoma were 84, 91 and 79%, respectively. These figures are much higher than those obtained by traditional (cohort-based) methods of survival analysis. A large difference in prognosis is still observed between the East and other parts of Europe. CONCLUSION Major improvement in prognosis for children with leukaemia or lymphoma has been ongoing in Europe during the 1990s, but further monitoring and investments are required to remove the large regional differences between European regions.
