[Show abstract][Hide abstract] ABSTRACT: Oral mucositis is a common and debilitating side effect of hematopoietic stem cell transplantation. Our study investigated parents' and children's experiences of oral mucositis treatment and whether the parents' perceptions accurately reflected the children's views.
We analysed 71 questionnaires completed by the parents of children who had undergone hematopoietic stem cell transplantation, together with 38 questionnaires completed by children who were seven-years-of-age or over.
The parent proxy and child self reports showed good to excellent agreement. For example, 86% of the parents and 83% of the children reported oral pain and 44% of the parents and 47% of the children reported difficulty swallowing often or very often. The majority of the parents (61%) were satisfied with the pain treatment that had been given to their child. However, the treatment provided for oral mucositis was not altogether consistent CONCLUSION: Oral mucositis affected the majority of the children undergoing hematopoietic stem cell transplantation, causing considerable pain and discomfort. The parent proxy reports proved to be reliable and are an important supplement to child self-reports on symptoms related to oral mucositis. But there is a clear need to establish more evidence-based care for children suffering from oral mucositis. This article is protected by copyright. All rights reserved.
[Show abstract][Hide abstract] ABSTRACT: We measured risk factors for CVD in 18 patients at a median of 18.2 yr after SCT and in sex and age-matched controls. Three patients (17%), but none of the controls, met the criteria for the MetS (p = 0.25). In the patients, we found higher levels of triglycerides (0.94 vs. 0.62 mm, p = 0.019), total cholesterol (5.1 vs. 4.0 mm, p = 0.017), LDL (3.4 vs. 2.6 mm, p = 0.019), apolipoprotein B (1.04 vs. 0.74 g/L, p = 0.004), apolipoprotein B/A1 ratio (0.7 vs. 0.5, p = 0.026), and lower levels of adiponectin (4.9 vs. 7.5 mg/L, p = 0.008) than in the controls. The patients had a lower GHmax (9 vs. 20.7 mU/L, p = 0.002). GHmax was significantly correlated inversely with triglycerides (r = -0.64, p = 0.008), total cholesterol (r = -0.61, p = 0.011), apolipoprotein B (r = -0.60, p = 0.014), and apolipoprotein B/A1 ratio (r = -0.66, p = 0.005). We recorded a significantly thicker carotid intima layer among the patients than among matched controls (0.15 vs. 0.13 mm, p = 0.034). The level of adiponectin correlated inversely with carotid intima thickness (r = -0.55, p = 0.023). After SCT in childhood, long-term survivors may be at risk of developing premature CVD.
[Show abstract][Hide abstract] ABSTRACT: Hepatic veno-occlusive disease is a leading cause of morbidity and mortality after haemopoietic stem-cell transplantation (HSCT). We aimed to assess whether defibrotide can reduce the incidence of veno-occlusive disease in this setting.
In our phase 3 open-label, randomised controlled trial, we enrolled patients at 28 European university hospitals or academic medical centres. Eligible patients were younger than 18 years, had undergone myeloablative conditioning before allogeneic or autologous HSCT, and had one or more risk factor for veno-occlusive disease based on modified Seattle criteria. We centrally assigned eligible participants on the basis of a computer-generated randomisation sequence (1:1), stratified by centre and presence of osteopetrosis, to receive intravenous defibrotide prophylaxis (treatment group) or not (control group). The primary endpoint was incidence of veno-occlusive disease by 30 days after HSCT, adjudicated by a masked, independent review committee, in eligible patients who consented to randomisation (intention-to-treat population), and was assessed with a competing risk approach. Patients in either group who developed veno-occlusive disease received defibrotide for treatment. We assessed adverse events to 180 days after HSCT in all patients who received allocated prophylaxis. This trial is registered with ClinicalTrials.gov, number NCT00272948.
Between Jan 25, 2006, and Jan 29, 2009, we enrolled 356 eligible patients to the intention-to-treat population. 22 (12%) of 180 patients randomly allocated to the defibrotide group had veno-occlusive disease by 30 days after HSCT compared with 35 (20%) of 176 controls (risk difference -7·7%, 95% CI -15·3 to -0·1; Z test for competing risk analysis p=0·0488; log-rank test p=0·0507). 154 (87%) of 177 patients in the defibrotide group had adverse events by day 180 compared with 155 (88%) of 176 controls.
Defibrotide prophylaxis seems to reduce incidence of veno-occlusive disease and is well tolerated. Thus, such prophylaxis could present a useful clinical option for this serious complication of HSCT.

[Show abstract][Hide abstract] ABSTRACT: The concept of sense of coherence (SOC) may be applied to explain individuals' resources for dealing with the stressors confronted in daily life. Little is known about what impact cancer in childhood may have on the development of SOC.
The objectives of this study were to compare SOC between long-term survivors of childhood cancer and a comparison group and to explore the need for current support among the survivors and the association between need for support and SOC.
Data were collected from 224 long-term survivors aged 18 to 37 years using the 13-item SOC scale and interviews. A matched comparison group (n = 283) randomly selected from the general population was included.
There was no significant difference in the mean SOC score between the survivors and the comparison group. Twenty percent of the survivors reported a need for support, a need significantly predicted by a low SOC, as well as surgery and/or radiation treatment often in combination with chemotherapy.
Long-term survivors of childhood cancer seem to have resources to cope with stressful situations in life to the same degree as people in general. Survivors with fewer resources to cope and those having received a more intense treatment were more likely to be in need of support.
The concept of SOC in nursing practice may be helpful to identify and discuss an individual's resources and impediments to health to better understand the need for support among survivors of childhood cancer.

[Show abstract][Hide abstract] ABSTRACT: We measured bone mineral density (BMD) with dual-energy X-ray absorptiometry in the total body, at the lumbar spine, at the femoral neck and in the total hip, in 18 young adults with a median of 18.2 years after SCT. Fifteen patients had undergone auto-SCT and all patients had received TBI. The patients had significantly lower BMD in the total body, at the femoral neck, and in the total hip compared with age- and sex-matched controls. Six of 18 patients (33%) had low bone mass (z-score <-1) at one or more measurement sites, as opposed to two of the controls (11%, P=0.29). We found no significant influence of growth hormone levels or of untreated hypogonadism on BMD variables. Levels of 25-hydroxy (25(OH)) vitamin D were lower among the patients (35.2 vs 48.8 nmol/L, P=0.044) and were significantly correlated with total body BMD in the patient group (r=0.55, P=0.021). All six patients with low bone mass had hypovitaminosis D (≤37 nmol/L as opposed to 4 of the 11 (36%) patients without low bone mass (P=0.035). In conclusion, we found decreased BMD in SCT survivors, which may in part be caused by 25(OH) vitamin D deficiency.

[Show abstract][Hide abstract] ABSTRACT: Impairment of pulmonary function after stem cell transplantation (SCT) in childhood has been reported before. However, long-term longitudinal studies are scarce.
We measured lung volumes and performed dynamic spirometry serially in 18 patients after SCT. At the last investigation, a median of 18.2 years after SCT, the patients were compared with 18 matched controls. The diffusing capacity (DLCO) was only compared cross-sectionally.
There was a significant increase in the prevalence of restrictive lung disease (RLD, total lung capacity <80% of that predicted) from 7% (1/14) before SCT to 28% (5/18) 5 years after SCT, and 61% (11/18) a median of 18.2 years after SCT (P = 0.002). In comparison, none of the controls had RLD (61% vs. 0%, P = 0.001). Before SCT, no patient had obstructive lung disease (OLD, forced expiratory volume in 1 sec/vital capacity <70). OLD was found in one of 18 patients (6%) 5 years after SCT but in none of the patients a median of 18.2 years after SCT. Three of the controls had OLD (P = 0.25). Eleven patients had diffusion impairment (DLCO <80% of that predicted), as opposed to none of the controls (P = 0.001). The DLCO corrected for alveolar volume was decreased in only two patients.
We documented an increase in the prevalence of RLD, but not of OLD, after SCT. At the last investigation, only two patients had diffusion impairment after correction for alveolar volume.

[Show abstract][Hide abstract] ABSTRACT: After SCT in childhood, survivors may develop disorders of glucose metabolism. The role of obesity is controversial. We measured insulin sensitivity using the homeostasis model assessment (HOMA) and the frequently sampled i.v. glucose tolerance test (FSIVGTT), as well as body composition using dual-energy X-ray absorptiometry in 18 young adults median 18.2 years after SCT and compared them with matched controls. We also measured growth hormone (GH) secretion, and levels of leptin and adiponectin. HOMA showed insulin resistance in eight patients (44%), as opposed to none of the controls (P=0.008) and FSIVGTT showed a decreased sensitivity index in the patients (2.98 vs 4.54 mU/L/min, P=0.042). Dual energy X-ray absorptiometry showed a higher percentage fat mass in the patients (34.9 vs 24.3%, P=0.011), which correlated inversely with the sensitivity index (r=-0.52, P=0.032). The patients had a lower peak value of GH (GH(max) 9 vs 20.7 mU/L, P=0.002). Time post SCT correlated with percentage fat mass and inversely with GH(max). The patients had higher levels of leptin and lower levels of adiponectin, even after adjustment for fat mass. We propose that the decreased insulin sensitivity may primarily be explained by the adverse body composition, which may owe to long-standing GH deficiency.

[Show abstract][Hide abstract] ABSTRACT: The objective was to compare sexual function, sexual experience and quality of partner relationship by gender in a cohort of long-term survivors of childhood cancer with a sample from the general population.
A 30-item self-reported postal questionnaire was completed by a cohort of 224 (64%) long-term survivors of childhood cancer and 283 (51%) randomly selected persons from the general population.
Male survivors more often reported periods of low sexual interest (p = 0.019), more frequently reported low sexual satisfaction (p = 0.015), less frequently reported feeling sexually attractive (p = 0.020) and reported a lower total number of sexual partners (p = 0.031) than males in the comparison group did. Males diagnosed with a central nervous system (CNS) tumour more frequently reported sexual arousal problems (p = 0.003), low sexual satisfaction (p = 0.021) and total number of sexual partners (p = 0.012) than did males with other diagnoses. There were no statistically significant differences regarding sexual function between the female survivors and the females in the comparison group.
The results indicate that cancer disease and treatment have more impact on sexual function of male survivors than on the sexual function of female survivors. Amongst the survivors, males diagnosed with CNS tumours were shown to be the most vulnerable group. Assessment of sexual function is recommended to be included in regular follow-ups after childhood cancer.

[Show abstract][Hide abstract] ABSTRACT: There is a need for more knowledge about how survivors of childhood cancer perceive their lives and what influence current health status has on their quality of life. The purpose was to describe this among a group of long-term survivors and among a comparison group.
Telephone interviews were performed with a cohort of 246 long-term survivors and 296 randomly selected from the general population using the Schedule for the Evaluation of Individual Quality of Life-Direct Weighting (SEIQoL-DW). The participants nominated the areas they considered to be most important in life and rated the current status of each area on a seven-point category scale. An overall individual index score was calculated as a measure of quality of life. Self-reported health status was assessed using the Short Form Health Survey (SF-36).
Long-term survivors rated their overall quality of life and self-reported health status almost in parity with the comparison group. In both groups, family life, relations to other people, work and career, interests and leisure activities were the areas most frequently reported to influence quality of life. The survivors only differed from the comparison group on one of eight SF-36 scales reflecting problems with daily activities owing to physical health.
Health status was not shown to have a major impact on overall quality of life, indicating that health and quality of life should be evaluated distinctively as different constructs. This should be taken in consideration in clinical care of children with childhood cancer and long-term survivors.

[Show abstract][Hide abstract] ABSTRACT: Conflicting conclusions can be drawn from the available data concerning antileukemic efficacy and risks of intrathecal (i.t.) chemoprophylaxis to children after hematopoietic SCT (HSCT). To address this, we enrolled six transplantation centers with similar treatment and patient material. Of the 397 children included, 136 patients had received post-HSCT i.t. treatment (i.t. group) and 261 had not (non-i.t. group). The two groups were, apart from the i.t. therapy given or not given, at equal risk of post-HSCT central nervous system (CNS) relapse, which was the primary endpoint studied. Isolated CNS relapses were observed in 2 (1.5%) patients from the i.t. group and 2 (1%) from the non-i.t. group. Combined relapses, including CNS, involved 4 (3%) patients from the i.t. group and 6 (2%) from the non-i.t. group. Overall survival and the occurrence of neurological side effects did not differ significantly between the groups. There was no statistically significant difference in the incidence of isolated or mixed CNS relapses between the two groups, suggesting little or no benefit from i.t. therapy post-HSCT in children.

[Show abstract][Hide abstract] ABSTRACT: We evaluated renal function at a median follow-up of 18 (range 10.3-22.1) years after total body irradiation in 18 patients treated with stem-cell transplantation (SCT) (autologous SCT in 15 and allogeneic SCT in three) for hematologic malignancies and compared them with 18 healthy controls. No patient had chronic graft-versus-host disease. We found no difference in glomerular filtration rate estimated from cystatin C (105 vs 111 ml/min/1.73 m(2), p = 0.28). Patients had higher albumin excretion (0.8 vs 0.4 mg/mmol, p = 0.001), but no patient had overt albuminuria (>200 mg/L). Patients had higher diastolic blood pressure (74 vs 67 mmHg, p = 0.003). Two patients (11%) had hypertension. Patients had lower tubular reabsorption of phosphate (0.78 vs 0.91 mmol/L, p = 0.014) and higher excretion of alpha-1-microglobulin (AMG/urine creatinine, 0.4 vs 0.25 mg/mmol, p = 0.038), which correlated with time after SCT (r = 0.6, p = 0.01). We found no difference in fractional excretion (FE) of other electrolytes, amino acid excretion, or urine osmolality. We conclude that renal function was relatively well preserved at a median follow-up of 18 years after childhood SCT. The higher albumin excretion in our patients is of concern, as is the association between excretion of AMG and time after SCT, suggesting that both glomerular and tubular function may deteriorate further.
[Show abstract][Hide abstract] ABSTRACT: The aim of the study was to describe how young adults who have survived childhood cancer consider their present life to be influenced by the cancer experience. A cohort of 246 long-term survivors were approached a median of 16 years after diagnosis. Semi-structured telephone interviews were conducted based on the Swedish version of the Schedule for the Evaluation of Individual Quality of Life-Direct Weighting (SEIQoL-DW). Interviews were analysed using content analyses. When asked if cancer negatively or positively currently affected their lives, 68% reported at least one negative consequence and 53% at least one positive consequence. The most frequently reported negative consequences include a variety of physical impairments and limitations in participating in activities; positive consequences describe a more positive view of life and of self. Women more often than men reported negative psychological impact, a changed body appearance and positive interaction with others. CNS tumours and combined treatment were somewhat associated to a higher extent of negative consequences. Overall, the results indicate that long-term survivors of childhood cancer are getting along quite well despite shortcomings.

[Show abstract][Hide abstract] ABSTRACT: At present, the literature on the efficacy and risks of i.t. chemotherapy to children after HSCT is scarce. Current practices to reduce the risk of leukemic relapse in the CNS after HSCT differ between centers of transplantation. We compared 74 patients (56 ALL/18 AML), who received i.t. therapy post-HSCT with 46 patients (36 ALL/10 AML) who did not receive post-HSCT i.t. therapy. The patients were transplanted at the University Children's Hospital, Uppsala or the Karolinska University Hospital, Huddinge, two Swedish transplantation units with different routines concerning i.t. therapy after HSCT. The primary end-point was the number of isolated CNS relapses. Secondary end-points were other types of relapse, death, and neurological complications. There was no statistically significant difference in the incidence of CNS relapses between the groups (p > 0.05). I.t. therapy did not reduce the overall incidence of isolated CNS relapse or mortality. Our study did not demonstrate a protective effect of i.t. therapy indicating that post-HSCT i.t. therapy may only be of limited use in the treatment of acute childhood leukemia. We conclude that with the risks present, i.t. therapy should be carefully evaluated, and only considered in high-risk cases.
