According to national cancer registry data in Japan, approximately 20,000 adolescents and young adults (AYAs, age 15–39 years) are newly diagnosed with cancer each year. Improvements in treatment and care for AYAs with cancer are included in the Phase Three Basic Plan to Promote Cancer Control Programs in Japan. This article reviews current cancer incidence and survival for AYAs with cancer in Japan using population-based cancer registry data. Mortality data through 2019 from the Vital Statistics of Japan are also described. Encouragingly, the 5-year survival probability for AYA cancers has continued to improve, in parallel with childhood cancers, and the mortality rate has decreased. There has been increasing attention to these vulnerable patients and improved partnerships and collaboration between adult and pediatric oncology; however, obstacles to the care of this population still exist at multiple levels. These obstacles relate to specific areas: research efforts and enrollment in clinical trials on AYA malignancies, AYA-specific psychosocial support such as education, financial support, and oncofertility care, and cancer care systems. It is important for Japanese oncologists, health care providers, and health policy makers to recognize that the AYA population remains vulnerable and still have unmet needs.

Aim We examined accuracy of nurses’ clinical judgement of graft‐versus‐host‐disease (GVHD) symptoms and related factors using Common Terminology Criteria for Adverse Events (CTCAE) for patients who developed chronic cutaneous GVHD after haematopoietic stem cell transplants. Design Cross‐sectional design using nationwide survey. Methods A questionnaire survey based on Tanner's clinical judgement model to assess patients with chronic cutaneous GVHD using CTCAE was used. Free‐text descriptions and statistical analyses of relationship between correct responses and demographic data were performed. Results The rate of correct responses for main symptoms of skin GVHD was

In addition to malignant diseases, hematopoietic stem cell transplantation (HSCT) is also a vital option as a curative therapy for non-malignant diseases, such as immunodeficiency, and other hematological disorders. Not only for malignant diseases, but for non-malignant diseases, cytotoxic therapy of conditioning regimens are associated with high risks of adverse effects; however, clinical details regarding the long term outcomes of cytotoxic therapy for non-malignant diseases are not documented yet. To clarify the endocrinological consequences of pediatric HSCT for non-malignant disease patients, we conducted a retrospective analysis. From 1983 to 2014, 75 patients that underwent HSCT for non-malignant diseases were selected for this study. Of these, 23 patients (19 men, 4 women) were continuously followed up in our institute, with regular health check-ups for late effects. Based on a multiple linear regression analysis, the glucocorticoid treatment duration for chronic graft-versus-host disease (cGVHD) and the conditioning regimen were found to be independent predictors of growth retardation. All four female patients developed hypogonadism, and required hormone replacement therapy. The conditioning regimen for the four female patients with hypogonadism was based on the use of alkylating agents, and two female patients were treated with a reduced-intensity conditioning (RIC) regimen. Our study revealed that even the RIC regimen was toxic for the gonads in female patients, and that the survivors of both non-malignant and malignant diseases should be followed up carefully after pediatric HSCT.

Female childhood cancer survivors who develop gonadal dysfunction require female hormone replacement therapy (HRT) from puberty until menopause. However, the support provided in such cases has not been studied. We investigated the physical and social characteristics and support needs of adult female childhood cancer survivors who underwent HRT. Forty-nine adult female childhood cancer survivors completed self-administered questionnaires. We compared the clinical characteristics, health status, and social conditions between a group that underwent HRT and a group that did not, and we surveyed support needs of the group that underwent HRT. The median age of the subjects was 25.0 years (range 20−41). Twenty subjects (40.8%) underwent HRT. A significantly high number of those who underwent HRT also underwent radiation therapy (p

We investigated the marital status and the presence or absence of children in survivors of childhood, adolescent and young adult (AYA) high-grade sarcoma and examined the influence of these factors on the quality of life (QOL) of these survivors. Thirty-eight survivors of childhood and AYA high-grade sarcoma (18 males, 20 females) participated in a questionnaire survey on marital status and presence or absence of children, as well as on the health-related QOL (HR-QOL), using the Short Form 36 Health Survey. Diagnoses among these survivors were osteosarcoma (28 participants), Ewing’s sarcoma (4 participants), synovial sarcoma (4 participants) and others (2 participants). Of the 18 males who participated in the survey, eight (44.4 %) were married, of whom five (62.5 %) had children. Fifteen (75.0 %) of the 20 females were married, of whom 14 (93.3 %) had children. The proportions of surviving male patients who were married and who had children, respectively, were lower than those of surviving female patients. The proportion of ifosfamide-treated men with children was significantly lower than that of non-ifosfamide-treated men (p = 0.018). With respect to the relationship between marital status and HR-QOL, the scores for the vitality and mental health domains of the SF-36 of survivors who were married were significantly higher than those of unmarried survivors. The results of our questionnaire survey reveal that among the male survivors of high-grade sarcoma, the proportions of those who were married and of those with children were lower than those of female survivors, suggesting that strategies providing support for marriage and child-rearing may be necessary for the male survivor group. In the married group, mental QOL was high.

BACKGROUND Family members of children with cancer experience various long-term effects as a result of cancer diagnosis and treatment. Therefore, comprehensive and long-term support is needed. As the employment rate of women has increased in recent years, support for working mothers with children diagnosed with cancer is also required. OBJECTIVE We investigated the following issues and relevant changes that working mothers of children diagnosed with cancer must deal with: (1) work change, (2) stress, (3) social support, (4) work motivation, and (5) employment status after diagnosis. METHODS A cross-sectional exploratory study design was used. Data were collected from 62 mothers of children who were diagnosed with cancer using self-report questionnaires. RESULTS Of the 32 mothers who worked at the time of diagnosis, 10 continued to work, 12 took an extended leave, and 10 quit working, and 70% lost motivation for work following diagnosis. Half of mothers who continued to work during treatment reported financial reasons. CONCLUSIONS These findings indicate that mothers who quit work following diagnosis did not initially consider a long leave of absence. Even mothers who continued to work during treatment desired a long leave of absence to care for their children. IMPLICATIONS FOR PRACTICE Nurses should provide mothers with explanations of the prospects after the completion of cancer treatment and determine their expectations for their lifestyle and work during treatment. We recommend that nurses confirm mothers' willingness to take a long leave of absence from work and give relevant advice about seeking financial assistance.

Chronic pain is a common problem in pediatric practice. The prevalence of chronic pain in children is >30%. Because pain indicates emotional expression as well as the physiological reaction toward infection, injury, and inflammation, both physiological and psychological assessments are essential to determine primary interventions for chronic pain. The Japanese Society of Psychosomatic Pediatrics Task Force of clinical practice guidelines for chronic pain in children and adolescents compiled clinical evidence and opinions of specialists associated with the primary care of pediatric chronic pain in the Japanese 'clinical guidelines for chronic pain in children and adolescents' in 2009, which are presented herein. The guidelines consist of three domains: general introduction to chronic pain; chronic abdominal pain; and chronic headache. Each section contains information on the physiological mechanism, psychological aspects, assessment methods, and primary interventions for pediatric chronic pain. These guidelines are expected to help disseminate knowledge on primary interventions for chronic pain in children and adolescents.

Japanese physicians' attitudes regarding the health-care needs of young adult childhood cancer survivors (CCSs) are not well described. Thus, we examined the self-reported preferences and knowledge of pediatric oncologists and surgeons.A mailed survey was sent to 858 physician members of the Japanese Society of Pediatric Oncology. We compared the responses of pediatric oncologists and pediatric surgeons.The pediatric oncologists' response rate was 56% (300 out of 533) and that of pediatric surgeons 32% (105 out of 325). The median age of respondents was 46 and 48 years, respectively; 79 and 84% were men. When comfort levels in caring for CCSs were described (i.e. 1 = very uncomfortable; 7 = very comfortable), the mean levels were 4.4 and 3.8 with CCSs ≤ 21 years, 3.6 and 3.6 with 21 yearsCCSs ≤ 30 years, and 2.8 and 3.3 with CCSs30 years, respectively. In clinical vignette questions, 62% of the pediatric oncologists and 43% of the surgeons answered three or more questions appropriately. Pediatric surgeons reported significantly lower familiarity with long-term follow-up guidelines than pediatric oncologists. Most pediatric oncologists and many surgeons conducted truth-telling of cancer diagnosis to adult CCSs now. They thought that the most important issues are an original long-term follow-up guideline suitable for the Japanese situation and collaborations with adult-based general physicians.Many Japanese pediatric oncologists are uncomfortable with caring for survivors as they age and have suboptimal knowledge regarding late effects. The change in truth-telling situation and preference for collaboration with adult-based physicians was demonstrated also in Japan.

Background Advances in medical science have enabled many children with chronic diseases to survive to adulthood. The transition of adult patients with childhood-onset chronic diseases from pediatric to adult healthcare systems has received attention in Europe and the United States. We conducted a questionnaire survey among 41 pediatricians at pediatric hospitals and 24 nurses specializing in adolescent care to compare the perception of transition of care from pediatric to adult healthcare services for such patients. Findings Three-fourths of the pediatricians and all of the nurses reported that transition programs were necessary. A higher proportion of the nurses realized the necessity of transition and had already developed such programs. Both pediatricians and nurses reported that a network covering the transition from pediatric to adult healthcare services has not been established to date. Conclusions It has been suggested that spreading the importance of a transition program among pediatricians and developing a pediatric-adult healthcare network would contribute to the biopsychosocial well-being of adult patients with childhood-onset chronic disease.
