[PMID: 39076127 DOI: 10.1542/peds.2024-066081] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2024] [Revised: 04/30/2024] [Accepted: 05/02/2024] [Indexed: 07/31/2024] Open
Abstract
CONTEXT There is an increasing population of childhood cancer survivors (CCS) at risk for treatment-related toxicities, including skeletal morbidities. Bone mineral density (BMD) is a proxy for bone health and reductions are associated with osteoporosis and fractures. OBJECTIVE To investigate bone health in CCS by conducting a systematic review and meta-analysis of BMD after completed treatments. DATA SOURCES We searched Medline, Embase, Cochrane, and Web of Science in May 2019 and updated in May 2023. STUDY SELECTION Studies reporting BMD Z-scores measured with dual-energy x-ray absorptiometry in CCS after treatment completion. DATA EXTRACTION We performed a pooled analysis of studies reporting BMD Z-scores and thereafter we analyzed studies comparing BMD in survivors and healthy controls. All analyses were performed based on the site of BMD measurement. RESULTS Of 4243 studies, 84 were included (N = 8106). The mean time off-treatment across the studies ranged from 2 months to 24 years. The overall pooled mean Z-score was -0.57 (95% confidence interval [CI] -0.59 to -0.55) in the whole-body, -0.84 (95% CI -0.86 to -0.83) in the lumbar spine, -0.79 (95% CI -0.81 to -0.77) in the femoral neck and -0.14 (95% CI -0.18 to -0.11) in the total hip. When comparing survivors with controls, BMD was significantly lower in survivors at all sites. LIMITATIONS English publications, study-level meta-analysis. CONCLUSIONS We showed a significant reduction of BMD Z-scores in CCS. Given the increased fracture risk already within -1 SD, these results emphasize the need for BMD surveillance and secondary prevention in CCS.

Methotrexate Chemotherapy Causes Growth Impairments, Vitamin D Deficiency, Bone Loss, and Altered Intestinal Metabolism-Effects of Calcitriol Supplementation. Cancers (Basel) 2023; 15:4367. [PMID: 37686643 PMCID: PMC10486381 DOI: 10.3390/cancers15174367] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2023] [Revised: 08/30/2023] [Accepted: 08/30/2023] [Indexed: 09/10/2023] Open
Abstract
Vitamin D deficiency or insufficiency is prevalent in childhood cancer patients and survivors after chemotherapy; further studies are needed to investigate the underlying aetiology and effectiveness of vitamin D supplementation in preventing chemotherapy-induced bone loss. This study used a rat model of treatment with antimetabolite methotrexate to investigate whether methotrexate chemotherapy causes vitamin D deficiency and if vitamin D supplementation attenuates the resultant bone loss. Methotrexate treatment (five daily injections) decreased serum vitamin D levels (from 52 to <30 ng/mL), reduced body and bone lengthening and tibial trabecular bone volume, and altered intestinal vitamin D metabolism, which was associated with intestinal mucosal damage known to cause malabsorption of nutrients, including dietary vitamin D and calcium. During the early stage after chemotherapy, mRNA expression increased for vitamin D activation enzyme CYP27B1 and for calcium-binding protein TRPV6 in the intestine. During the intestinal healing stage, expression of vitamin D catabolism enzyme CYP24 increased, and that of TRPV6 was normalised. Furthermore, subcutaneous calcitriol supplementation diminished methotrexate-induced bone loss due to its effect suppressing methotrexate-induced increased bone resorption. Thus, in young rats, methotrexate chemotherapy causes vitamin D deficiency, growth impairments, bone loss, and altered intestinal vitamin D metabolism, which are associated with intestinal damage, and vitamin D supplementation inhibits methotrexate-induced bone loss.

Bone Mineral Metabolism During Chemotherapy in Childhood Acute Lymphoblastic Leukemia. J Pediatr Hematol Oncol 2021; 43:172-175. [PMID: 32815875 DOI: 10.1097/mph.0000000000001908] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/25/2020] [Accepted: 07/09/2020] [Indexed: 11/26/2022]
Abstract
OBJECTIVE The aim of this study was to evaluate levels of vitamin D, bone mineral density (BMD), and radiograph features at diagnosis and after 6 months of chemotherapy in patients with acute lymphoblastic leukemia (ALL). Vitamin D levels were also correlated with BMD and radiograph features. MATERIALS AND METHODS 25-Hydroxy vitamin D [25(OH)D] levels, BMD, and radiograph features were assessed in 50 newly diagnosed patients of ALL in the age group of 2 to 14 years. A total of 30 age-matched and sex-matched children were recruited as controls. Vitamin D deficiency was defined as 25(OH)D <10 ng/mL, Vitamin D insufficiency as 10 to 29 ng/mL, and Vitamin D sufficiency as ≥30 ng/mL. Enzyme immunoassay (EIA) was used for the quantitative measurement of 25(OH)D levels in plasma and a LUNAR DPX NT bone densitometer was used for the assessment of BMD. RESULTS The mean age of the patients was 6.3 years, with a male:female ratio of 1.38:1. The mean 25(OH)D levels were 31.90±16.90 ng/mL in patients at diagnosis against 41.63±20.50 ng/mL in controls (P=0.02). Levels were 18.50±11.10 ng/mL postchemotherapy (P=0.00). Female sex was a risk factor for deficient 25(OH)D levels. There was a significant decrease in BMD postchemotherapy in the age groups of 5 to 10 and above 10 years at the femoral neck. Osteopenic changes were observed in more number of patients after 6 months of chemotherapy. There was a significant correlation between vitamin D levels, BMD, and osteopenic changes. CONCLUSIONS Vitamin D deficiency was common among ALL patients, which worsened after chemotherapy. This had a significant correlation with BMD and osteopenic changes in radiograph.

Vitamin D supplementation for children with cancer: A systematic review and consensus recommendations. Cancer Med 2021; 10:4177-4194. [PMID: 34100559 PMCID: PMC8267124 DOI: 10.1002/cam4.4013] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2020] [Revised: 04/22/2021] [Accepted: 04/26/2021] [Indexed: 12/29/2022] Open
Abstract
Background Prevalent vitamin D deficiency (VDD) and low bone mineral density (BMD) have led to vitamin D supplementation for children with cancer, regardless vitamin D status. However, it remains unsettled whether this enhances bone strength. We sought to address this issue by carrying out a systematic review of the literature. Methods We conducted a literature search using PubMed, Embase, and Cochrane databases. Studies including children up to 5 years after cancer therapy were assessed for the association between 25‐hydroxyvitamin D (25OHD) levels and BMD Z‐scores or fractures, and the effect of vitamin D supplementation on BMD or fractures. Evidence quality was assessed using the GRADE methodology. Results Nineteen studies (16 observational and 3 interventional, mainly involving children with hematologic malignancies) were included. One study which analyzed 25OHD as a threshold variable (≤10 ng/ml) found a significant association between 25OHD levels and BMD Z‐scores, while 25OHD as a continuous variable was not significantly associated with BMD Z‐scores in 14 observational studies. We found neither a significant association between lower 25OHD levels and fractures (2 studies), nor between vitamin D (and calcium) supplementation and BMD or fracture frequency (3 studies) (very low quality evidence). Conclusion There is a lack of evidence for an effect of vitamin D (and calcium) supplementation on BMD or fractures in children with cancer. Further research is needed; until then, we recommend dietary vitamin D/calcium intake in keeping with standard national guidelines, and periodic 25OHD monitoring to detect levels <20 ng/ml. Vitamin D/calcium supplementation is recommended in children with low levels, to maintain levels ≥20 ng/ml year‐long.

Bone Mineral Density Evolution and Its Determinants in Long-term Survivors of Childhood Acute Leukemia: A Leucémies Enfants Adolescents Study. Hemasphere 2021; 5:e518. [PMID: 33458594 PMCID: PMC7806242 DOI: 10.1097/hs9.0000000000000518] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2020] [Accepted: 11/09/2020] [Indexed: 11/27/2022] Open
Abstract
This prospective study aimed to analyze determinants that can influence bone mineral density evolution in childhood acute leukemia survivors. Patients included were selected from the long-term follow-up LEA cohort and had dual energy radiograph absorptiometry scan between 10 and 18 years and after the age of 18. All scans were centrally reviewed. Bone mineral density was measured at the lumbar spine, femoral neck, total hip, and whole body, and expressed as z-score. Eighty-nine patients (female 39, lymphoblastic leukemia 68, relapse 25, hematopoietic stem cell transplantation 44, and mean age 15.4 and 20.1 years at the first and second scans, respectively) were studied. The first and second scan z-scores were significantly correlated (P < 10−3). Mean femoral neck and total hip z-scores improved significantly between the first and second scans, whereas no significant evolution occurred at the lumbar spine and whole-body level. On the second evaluation, 14.6% of patients had z-score <−2 at the lumbar spine and 4.3% at the femoral neck level. Gender, type of leukemia, transplantation, relapse, cumulative corticosteroid doses, or growth hormone deficiency did not have any significant impact on z-score variation. Younger age at diagnosis (≤8.5 years) proved an unfavorable risk factor for z-score evolution at the lumbar spine (P = 0.041); the trend did not reach statistical significance for metabolic syndrome (P = 0.054). At the femoral neck, both were associated with unfavorable z-score evolution (P = 0.003 and 0.025, respectively). Patients treated at a younger age and those with metabolic syndrome seem to be at higher risk of bone mineral density decline and should benefit from specific interventions.

Abstract
Objective To describe the prevalence of obesity and sarcopenia among survivors of childhood acute lymphoblastic leukemia (ALL) using DEXA scan, and study associated risk factors. Methods This case control study was conducted between July, 2013 and June, 2014 at a tertiary care cancer centre in India. Study participants included 65 survivors of childhood ALL who were <18 years of age at diagnosis, treated between years 1996 and 2008, and were at least two years since completion of therapy. The controls included 50 matched siblings. Dual energy X-ray absorptiometry (DEXA) was used to study the body composition (body fat percentage, BF% and lean body mass, LBM) of the participants and controls. McCarthys body fat reference data were applied and logistic regression analysis was used to study various risk factors. Results At a median (range) follow-up of 5 (7.217.2) years, BF% (DEXA) identified a significantly higher prevalence of obesity of 21.5% (14/65) and sarcopenic obesity (14%) among survivors as compared to the controls (0/50, P<0.001), while the prevalence of sarcopenia as detected by LBM was similar at 60% (39/65) and 56% (28/50), respectively. On multivariate analysis, age at evaluation, high-risk disease and cranial irradiation were independently associated with high likelihood of obesity, while none of the factors predicted sarcopenia. Conclusion High prevalence of obesity and sarcopenic obesity were observed among survivors of childhood ALL.

Abstract
Survivorship care is a major area of focus in the holistic management of childhood cancer with current knowledge and information almost exclusively from high-income countries. In this review, we summarize the state of scientific knowledge, service delivery, advocacy initiatives, and research efforts in this field in India. Twenty-one single-center studies published until today (20 in the last decade) confirm some of the well-documented issues in childhood cancer survivors and highlight the high prevalence of hepatitis B and hepatitis C infection in our survivors. Heterogeneity in methodology, outcome metrics, and quality precludes drawing further conclusions, and the ongoing multicenter Indian Pediatric Oncology Group study would address this. Besides the usual model of follow-up clinics in hospital settings, innovative models of service delivery led by not-for-profit organizations are being developed. Advocacy initiatives driven by survivors and support groups are also under way. All of these portend a promising future.

Abstract
BACKGROUND Survivors of childhood leukemia/lymphoma are at increased risk for reduced bone mineral density (BMD). The authors sought to determine the frequency of reduced BMD detected by off-therapy surveillance, factors associated with reduced BMD, and the association of reduced BMD with fractures. METHODS This cross-sectional study included childhood leukemia/lymphoma survivors attending 2 survivorship clinics who received guideline-recommended BMD surveillance ≥2 years post-therapy with dual-energy x-ray absorptiometry (from January 1, 2004 to August 31, 2016). Lumbar spine BMD z-scores were height-for-age-adjusted. Low and very low BMD were >1 SD and >2 SDs below norms, respectively. Treatment, chronic conditions, and fractures were abstracted from medical records. Logistic regression was used to examine the association of low BMD with patient/treatment factors and fractures. RESULTS In total, 542 patients (51.5% female) with a mean age of 15.5 years (range, 4.4-52.2 years) who were 6 years post-therapy (range, 2.0-35.1 years) were evaluated, including 116 who reported post-therapy fractures. Lumbar spine low BMD was identified in 17.2% of survivors, and very low BMD was identified in 3.5% of survivors, but frequencies varied considerably between subgroups; 10.8% of survivors aged 15 to 19 years at diagnosis had very low BMD. In multivariable analyses, older age at diagnosis, white race, and being underweight were significantly associated with low BMD. Survivors with low BMD had greater odds of nondigit fractures (odds ratio, 2.2; 95% CI, 1.3-3.7) and specifically long-bone fractures (odds ratio, 2.7; 95% CI, 1.5-4.7). CONCLUSIONS In this study of childhood leukemia/lymphoma survivors undergoing guideline-recommended dual-energy x-ray absorptiometry surveillance, patients who were older at diagnosis, white, and underweight were at the highest risk for lumbar spine low BMD. Low BMD was associated with a greater risk of fractures, emphasizing the clinical importance of surveillance.

Abstract
BACKGROUND An increase in survival rates of childhood cancer is associated with long-term health issues in survivors. METHODS We conducted a systematic review and meta-analysis comparing health status-related endpoints in childhood cancer survivors (CCS) versus controls. RESULTS Eighty-six studies (n = 98,480 participants, 62% CCS) were included in the review. Of these, 73 studies (n = 96,550, 63% CCS) could be meta-analyzed. CCS showed a lower left ventricular ejection and fractional shortening (SMD=-0.59 and -0.55, respectively, both p < 0.01 [n=1,824 and 1,880]), a lower HDL-cholesterol concentration (SMD=-0.48, p<0.001, n=1,378) and a higher waist-to-hip ratio (SMD=0.61, p < 0.01, n=229) than their healthy peers. No significant differences were found for the remaining endpoints. CONCLUSIONS CCS is associated with a lower left ventricular function and HDL-cholesterol level, and a higher waist-to-hip ratio than healthy controls. These findings support the need to closely monitor the cardiometabolic health status of CCS and to implement preventive lifestyle interventions for this population.

Abstract
Reduced bone mineral density (BMD) is a well-known complication in childhood acute lymphoblastic leukemia (ALL) survivors; the optimal method to assess BMD is still debated. We studied BMD by quantitative ultrasound (QUS) in 72 ALL survivors, and evaluated any correlation with cumulative doses of steroids and cytotoxic agents. Mean age at diagnosis was 61±45 months, while mean age at QUS was 318.3±129.6 months; mean period of follow-up was 41.2±37.8 months. Mean amplitude-dependent speed of sound z-score was -1.22±1.19. Ten survivors (13.8%) presented a z-score below -2 SD. A negative correlation was found between amplitude-dependent speed of sound z-score and age at diagnosis (P=0.01). A positive correlation was observed with length of follow-up (P=0.01). No correlation was found with cytotoxic drugs. This study represents the largest cohort of childhood ALL survivors studied by QUS. Our results suggest that QUS for its characteristics of being radiation free may be an effective option to assess BMD in pediatric age. In addition, our data outline the importance to improve the awareness about the specific expression of this complication in the pediatric age, concerning the major determinants of bone impairment, which are the disease itself and the phase of bone growth when the disease occurs.

Abstract
INTRODUCTION One aim of the long-term care in survivors from acute lymphoblastic leukemia (ALL) during childhood is to avoid or limit complications caused by aggressive therapeutic strategies. AREAS COVERED ALL survivors are a heterogeneous group according to therapeutic protocols. In the last decades, cranial radiotherapy (cRT) has been largely replaced by intrathecal chemotherapy (CT) with a reduction of endocrine sequelae. Published studies are generally difficult to be interpreted because patients were treated according to different risk-adapted protocols and results are conflicting. We perform this review on endocrine long-term effects in childhood ALL survivors focusing on studies published in the last decades. Articles were selected using the following terms (Mesh terms): 'acute lymphoblastic leukemia' AND 'survivors' AND 'childhood' AND 'growth/puberty/fertility/obesity/metabolic syndrome/bone'. EXPERT COMMENTARY Most childhood ALL survivors treated with CT alone attain normal height and have adequate pubertal development. Despite recent protocols improvements, ALL survivors still develop long-term metabolic complications (overweight, obesity, and cardiovascular disease) especially the female gender and patients with an increased body mass index (BMI) at diagnosis. The aim of this review is to describe the state of the art on these topics. We should be able to anticipate, prevent, and treat endocrine long-term morbidities through a well-established follow-up strategy.
