ABSTRACT: BACKGROUND: The present study aimed to investigate the relationship between school attendance and infection requiring antimicrobial treatment in children undergoing treatment for cancer. PROCEDURE: A national cohort of children aged 7-16 years undergoing cancer treatment was assessed during two observation periods of 19 days each, 1 month (n = 89) and 2.5 months (n = 89) poststart of treatment. Children free from infection at start of each observation period were included. Multivariable logistic regression analyses were performed including factors potentially associated with start of antimicrobial treatment. RESULTS: Twenty-seven (30%) children started antimicrobial treatment during the first observation period. Factors associated with an increased risk of starting antimicrobial treatment were diagnosed with sarcoma (OR = 24.37, P = 0.002) or non-Hodgkin lymphoma (OR = 17.57, P = 0.025), having neutropenia (OR = 5.92, P = 0.020) and age less than 13 years (OR = 8.54, P = 0.014). During the second observation period, when 20 (22%) children started antimicrobial treatment, the probability of starting treatment was increased in children with neutropenia (OR = 4.25, P = 0.007). There was no statistically significant association between starting treatment for infection and school attendance. CONCLUSIONS: In this study, children attending school while undergoing cancer treatment did not run a higher risk of starting antimicrobial treatment than children absent from school. However, there is a need for further studies evaluating risk of infections in children with ongoing cancer treatment. Pediatr Blood Cancer © 2013 Wiley Periodicals, Inc.

ABSTRACT: BACKGROUND: Chronic health conditions are known to be both abundant and severe after pediatric hematopoietic stem cell transplantation (SCT). The present objective was to investigate the impact of disease and treatment on individual QoL and health-related quality of life (HRQoL) in long-term survivors of childhood lymphoblastic malignancy treated with conventional therapy versus SCT. PROCEDURE: Survivors of lymphoblastic malignancy treated with (n = 18) or without (n = 52) SCT were recruited a median follow-up time of 18 and 14 years, respectively. The indication for SCT was relapsed disease in 17 of 18 cases. Autologous stem cells were used in 15 cases. Total body irradiation (TBI) was included in the conditioning regimen for all SCT patients. A cross-sectional study was conducted using two validated instruments: SEIQoL-DW (individual QoL) and SF-36 (HRQoL). Content analysis was used to analyze SEIQoL-DW and an overall QoL index score was calculated. Two multiple linear regression analyses were performed to detect factors influencing outcomes. RESULTS: Poorer ratings of overall QoL and more negative consequences related to physical dysfunctions were shown in the SCT group. The findings indicate that being unemployed or on sick leave are associated with a decline in HRQoL and individual QoL rather than SCT, cranial radiation therapy, present age, or sex. CONCLUSION: In this small sample of long-term survivors of SCT, QoL seems reasonably good and similar to that of those having received conventional therapy. However, managing an employment must be acknowledged as an important part of life that has a great impact on QoL. Pediatr Blood Cancer © 2013 Wiley Periodicals, Inc.

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.

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.

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.

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.

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.

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.

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.

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.

ABSTRACT: TEN and HUS are challenging complications with excessive mortality after HSCT. We report the development of these two conditions in combination in a nine-yr-old boy after HSCT from an unrelated donor. TEN with skin detachment of more than 90% of body surface area developed after initial treatment for GvHD. Within a few days of admission to the burns unit, the patient developed severe hemolysis, hypertension, thrombocytopenia, and acute renal failure consistent with HUS, apparently caused by CSA. The management included intensive care in a burns unit, accelerated drug removal using plasmapheresis, and a dedicated multi-disciplinary team approach to balance immunosuppression and infections management in a situation with extensive skin detachment. The patient survived and recovered renal function but requires continued treatment for severe GvHD. Suspecting and identifying causative drugs together with meticulous supportive care in the burns unit is essential in the management of these patients and long-term survival is possible.

ABSTRACT: Parathyroid function was recently reported to be affected in more than one-third of pediatric BMT patients conditioned without irradiation. Our aim was to describe parathyroid function in children with malignant hematological disease after autologous BMT with and without TBI. PTH, albumin-corrected serum calcium, and serum phosphate were analyzed in 35 children followed for six months to nine yr after BMT. Twelve patients were conditioned with chemotherapy alone, and 23 patients received TBI as well. In the TBI group, 11 patients had previously received additional CRT. We found normal levels of PTH in children post-BMT, with the exception of four patients (11%) who showed transient PTH elevation during the first year of follow-up, There was no difference between those who had received irradiation and those who had not. Serum calcium was unchanged after BMT. An age-corrected quotient of serum phosphate decreased slightly. Renal function which was normal before BMT decreased slightly in both groups after BMT, but was within the normal range. Parathyroid function was found to be normal during the time frame of this study, irrespective of whether irradiation had been given.

ABSTRACT: The clinical value of monitoring of Epstein-Barr virus (EBV) viraemia by quantitative polymerase chain reaction during 1 y was evaluated. 39 recipients of allogeneic hematopoietic stem cell transplantation (SCT) were followed. More than 100 EBV genome equivalents (gEq)/ml in blood or plasma were found in 16/39 patients (41%) at 34 d (range 1-139) post-transplant. Seven of these 16 patients developed EBV disease; 3 post-transplant lymphoproliferative disease (PTLD), 1 myelitis, 1 encephalitis and 2 reactivations with fever. EBV diseases were only found in the high-risk group among recipients of mismatched related or unrelated donor grafts or in patients who underwent reduced-intensity conditioning. In this group, 3/20 (15%) developed PTLD. Conditioning with antithymocyte globulin was significantly associated with EBV disease (p<0.01). EBV load in plasma was more strongly associated with EBV disease than viral load in blood. A cut-off level of 1000 gEq/ml plasma distinguished EBV disease from asymptomatic viraemia, but not PTLD from other EBV diseases. Weekly monitoring of EBV load in plasma in high-risk patients in the first 3 months following SCT seems to be of value for prediction of EBV disease. Therapy for PTLD including rituximab was evaluated during 2 y and showed response in 4/6 cases.

ABSTRACT: One aspect of organizing medical follow-up for adult survivors of childhood cancer is to determine to what extent the former patient experiences a need for health services. In the present paper, we studied how the healthcare needs, both subjectively and objectively, were fulfilled for our former patients.
335 survivors over 18 y of age, with a follow-up time of more than 5 y after completion of therapy, were sent a questionnaire probing their present use of health services.
The response rate was 73%. A majority (60%) of the survivors had no regular follow-up visits, and 42% of these reported that they missed not having one. More than one third were thus far dissatisfied with the follow-up programme. Only 3% of those who had regular follow-ups found them "unnecessary". Complaints subjectively related to their diseases or treatments were reported by 47%. Out of all responders, 34% did not miss having regular follow-up visits. Neither perceived disease-related complaints nor radiation therapy was a predictor for having a scheduled follow-up visit.
In the absence of a long-term follow-up programme, many survivors were not receiving proper medical healthcare, whether from their perspective or from a professional one.

ABSTRACT: To describe spontaneous cortisol secretion in children after autologous bone marrow transplantation (BMT) for acute leukaemia and lymphoma.
Spontaneous cortisol secretion was analysed in 39 children before and after BMT. Thirteen patients were conditioned with chemotherapy only (group 1), and 26 patients also with total body irradiation (TBI). In the TBI group, 14 patients had received no additional irradiation (group 2), whereas 12 patients had received cranial irradiation (CRT) previously (group 3).
Before BMT, in comparison with group 1, mean morning cortisol was significantly lower in group 2 (252 vs 415 mmol/l, p = 0.004), but not in group 3 (vs 312 mmol/l, p = 0.12). There was no change in group 1 six months after BMT (to 379 nmol/l), whereas morning cortisol increased significantly in group 2 and group 3 (to 386 and 343 nmol/l, respectively; p < 0.05). The change in mean morning cortisol correlated negatively with pretransplant morning cortisol (r = -0.63, p < 0.001). Neither TBI nor CRT were associated with changes in morning cortisol.
Spontaneous cortisol secretion is maintained after BMT irrespective of whether cranial or total body irradiation has been given or not.

ABSTRACT: A duplex quantitative real-time PCR (qPCR) assay was designed to detect both the polymerase gene (pol) and the glycoprotein gene (gB) of cytomegalovirus (CMV). The detection limit of the qPCR was determined to be 1 to 3 copies/reaction and the linear measure interval was 10(3) to 10(8) copies/ml. The qPCR system was compared to the COBAS Amplicor CMV Monitor test (COBAS) by an analysis of 138 plasma samples. Both systems detected CMV in 71 cases and had negative results for 33 samples. In addition, 34 samples were positive by qPCR and negative by the COBAS assay, but in no case was the COBAS result positive and the qPCR result negative. Thus, qPCR detected 48% more positive cases than the COBAS method. For samples with > or = 10(5) copies/ml by qPCR, a saturation effect was seen in the COBAS assay and quantification required dilution. Copy numbers for pol and gB by qPCR generally agreed. However, the reproducibility of qPCR assays and the need for an international standard are discussed. Discrepant copy numbers for pol and gB by qPCR were found for samples from two patients, and sequence analysis revealed that the corresponding CMV strains were mismatched at four nucleotide positions compared with the gB fragment primer sequences. In conclusion, a duplex qPCR assay in a real-time format facilitates quantitative measurements and minimizes the risk of false-negative results.
