Hematopoietic stem cell transplantation is a therapeutic strategy for several oncohematological diseases. It increases survival rates but leads to a high incidence of related effects. The objective of this paper was to examine the existing literature on physical exercise interventions among pediatric HSCT recipients to explore the most often utilized rehabilitative assessment and treatment tools. Studies published from 2002 to April 1, 2015 were selected: 10 studies were included. A previous literary review has shown that rehabilitation programs have a positive impact on quality of life. Our analysis identified some significant outcome variables and shared intervention areas.  相似文献

Retinoid therapy has contributed to improved outcomes in neuroblastoma. Clinical trials of fenretinide report favorable toxicity and disease stabilization in patients with high risk (HR) neuroblastoma. Skeletal effects have been described with other retinoids, but not with fenretinide to date. Two patients with HR, metastatic, refractory neuroblastoma received protracted courses of oral fenretinide for more than 5 years’ duration. Both developed premature long bone physeal closure, causing limb length discrepancies; their neuroblastoma remains in remission. The radiographic and clinical findings reported suggest these skeletal abnormalities may be a consequence of treatment with 13‐cis‐retinoic acid (13cisRA) followed by prolonged oral fenretinide exposure.  相似文献

Introduction: Survival of ovarian cancer patients is still unsatisfactory despite the introduction of new diagnostic and therapeutic methods. Women with advanced ovarian cancer with long-term survival are at persistent risk of anxiety and reactive depression due to poor prognosis and risk of burdensome symptoms. The aim of the study was to assess changes in anxiety and depression during multimodality ovarian cancer treatment and to identify correlates of anxiety and depression.

Method: The study included 106 consecutive patients with advanced ovarian cancer. Mean age of the study group was 53.9 years (SD = 10.8, range: 23–79). The participants completed Hospital Anxiety and Depression Scale and State-Trait Anxiety Inventory four times: prior to and one week after surgery, and before the second and the fourth course of adjuvant chemotherapy. Multivariate analysis was performed to identify the independent determinants of distress at various stages of treatment.

Results: The level of anxiety and the prevalence of pathological anxiety (74%) were the highest prior to surgery and gradually decreased thereafter. Irrespective of the treatment stage, the level of anxiety was higher than the corresponding level of depression. History of abortion, presence of intestinal stoma, poor general status, residual disease and time from the initial diagnosis were the main determinants of distress in ovarian cancer patients.

Conclusions: Significant changes in the level of anxiety and slight fluctuations in the depression level experienced during ovarian cancer treatment are mostly determined by clinical variables. Identification of individuals with psychological comorbidities is a vital component of patient-oriented multidisciplinary care.  相似文献
