Abstract
BACKGROUND Changes in bone age and tooth development are late side effects of cancer therapy and can be identified by imaging examination. AIM To evaluate the late effects of antineoplastic treatment on bone age and dental development in childhood cancer survivors. DESIGN This is a retrospective case-control study on paediatric cancer survivors of both sexes who underwent antineoplastic treatment with 5-15 years of survival. Carpal radiographs were assessed for bone age and growth curve, and panoramic radiographs were used to evaluate dental development and alterations. Carpal radiographs were analyzed using the Greulich and Pyle inspection method, and the Martins and Sakima method was used to analyze the growth curve. All tests were applied with a confidence level of 95%. RESULTS The study and control groups comprised 28 and 56 patients, respectively. There was no significant difference in bone age and growth curve between the study and control groups. Nonetheless, when sex was compared to chronological and bone ages, there was a significant difference in bone age (p = 0.019) and an underestimation in both groups and sexes in the Greulich and Pyle method. As to late dental effects, dental agenesia, microdontia, gyroversion, and unerupted teeth were found. Dental shape alterations mainly involve the root region. CONCLUSION Close multidisciplinary collaboration is necessary during the follow-up period of young patients who have survived cancer.

Abstract
INTRODUCTION The increase in survival rates in children treated for cancer has been accompanied by a rise in sequelae in permanent teeth. The aim of the study was to correlate the type of cancer therapy administered to patients during early childhood and the dental sequelae recorded in survivors. MATERIAL AND METHODS Single-center retrospective cohort study carried out at the Children's University Hospital of Sant Joan de Déu in Barcelona, Spain. Hundred and nine patients who had received cancer treatment during early childhood were randomly examined and grouped according to diagnosis and cancer therapy received. The type of therapy was correlated with the number and severity of dental lesions that patients presented in adolescence. RESULTS Dental sequelae of some kind were present in 85.3% of patients. Microdontia was the most prevalent (52.3%). Treatment with alkylating agents had a relative risk of presenting moderate lesions of 3.36 (1.18-9.60), and one of 2.29 (1.07-4.91) of presenting severe lesions. Topoisomerase inhibitors and cytotoxic antibiotics presented relative risks of 1.6 (1.07-2.38) and 2.08 (1.02-4.26) of root alterations and agenesis, respectively. CONCLUSIONS Treatment with alkylating agents together with cytotoxic antibiotics and topoisomerase inhibitors was associated with a higher relative risk of microdontia, agenesis, and root shortening.

Abstract
The multidrug nature of anticancer treatment and different treatment protocols used in the studies are likely to be a major limitation in establishing real risk factors determining the occurrence of dental abnormalities. The authors aimed to establish a relationship between the duration and the dose of chemotherapy and the number of tooth adverse effects in the group receiving the same treatment. Of the 40 anticancer therapy recipients who attended the outpatient dental clinic, 7 leukemia survivors receiving the treatment according to the ALL IC-BFM 2002 protocol were selected. The study group consisted of four females and three males aged 92 to 207 months at the time of dental examination and 29 to 91 months at leukemia diagnosis. As a result of the clinical and radiological examination, dental abnormalities such as agenesis, tooth size reduction, root abnormalities, and taurodontia were identified, and the medical records of all survivors were reviewed in terms of drugs administered, their doses, and treatment schedules. No correlation was observed between the treatment duration of an intensive therapy, the entire therapy, and the number of tooth abnormalities. No relationship was also found between the number of dental abnormalities and the cumulative dose of vincristine, L-asparaginase, methotrexate, cyclophosphamide, cytarabine, and 6-mercaptopurine. The age at the onset of antineoplastic therapy is likely to be the strongest risk factor for toxic injury during tooth development.

Dental caries and dental developmental defects as adverse effects of antineoplastic treatment in childhood cancer survivors. Eur Arch Paediatr Dent 2023:10.1007/s40368-023-00789-z. [PMID: 36906732 DOI: 10.1007/s40368-023-00789-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2022] [Accepted: 02/23/2023] [Indexed: 03/13/2023]
Abstract
PURPOSE To evaluate the prevalence of dental caries and dental developmental defects (DDD) in childhood cancer survivors (CCS) and identify disease and treatment-related risk factors. METHODS CCS aged up to 21 years, diagnosed with a malignancy before the age of 10 years and in remission for at least one year were included. Data were collected from patients' medical records and through a clinical examination where presence of dental caries and prevalence of DDD were recorded. Fisher's exact test was used to assess possible correlations and multivariate regression analysis to determine risk factors for defect development. RESULTS Seventy CCS with a mean chronological age of 11.2 years at the time of examination, mean age at cancer diagnosis of 4.17 years, and a mean post-treatment follow-up time of 5.48 years were included. Mean DMFT/dmft was 1.31, with 29% of survivors presenting with at least one carious lesion. Younger patients on the day of examination and patients treated with higher radiation dose, showed significantly higher prevalence of dental caries. The prevalence of DDD was 59%, with demarcated opacities being the defect most commonly observed (40%). Age at dental examination, diagnosis, age at diagnosis, and time that have elapsed since the end of treatment were the factors significantly affecting its prevalence. Regression analysis revealed that age at examination was the only factor significantly associated with the presence of coronal defects. CONCLUSION A great number of CCS presented with at least one carious lesion or a DDD, with the prevalence being significantly associated with various disease-specific characteristics, but age at dental examination the only significant predictor.

Abstract
OBJECTIVE This study aimed to investigate the prevalence and extent of dental developmental complications in patients who have undergone pediatric hematopoietic stem cell transplantation (SCT) and identify the risk factors. MATERIALS AND METHODS We retrospectively investigated the clinical data warehouse of the Catholic Medical Center information system for identifying patients who: 1) visited the Department of Pediatrics between 2009 and 2019, 2) underwent SCT under the age of 10, and 3) had panoramic radiographs. Thus 153 patients were included in this study. The prevalence and extent of tooth agenesis, microdontia, and root malformation were assessed using panoramic radiographs obtained after SCT, and the risk factors were analyzed using regression analysis. RESULTS All 153 patients had at least one dental anomaly. When grouped according to the age at initial chemotherapy (≤ 2.5; 2.6-5.0; 5.1-7.5; > 7.5 years), the prevalence of agenesis showed statistically significant differences among the different age groups (P < 0.001). The prevalence of agenesis was highest in the youngest age group. As the initial age at chemotherapy increased, the number of affected teeth per patient decreased for all three anomalies. The location of the affected tooth was also influenced by the age at initial chemotherapy. Regression analysis demonstrated that young age at initial chemotherapy was a risk-increasing factor for tooth agenesis and microdontia. CONCLUSIONS The age at initial chemotherapy may be a critical factor in determining the type, extent, and location of dental complications after SCT. These results suggest that careful dental follow-up and timely treatment are recommended for pediatric patients undergoing SCT.

Abstract
Chemotherapy used on pediatric patients especially those below 3 years of age causes disturbances in dental development. The aim of this case report was to present the late dental effects of chemotherapy in a patient treated for anaplastic ependymoma (WHO III) at an early age. Radiographic findings at the age of 9 years showed oligomicrodontia of six teeth, maxillary lateral incisors, and maxillary and mandibular first premolars. Pediatric cancer survivors after chemotherapy have an increased risk of one or more dental development disorders. To ensure proper dental care and to assess the long-term effects on oral health, tooth development, and occlusion, the involvement of a dentist is crucial. Adequate diagnosis and well-planned treatment of the dental defect can significantly improve patient oral health-related quality of life.

Abstract
An idea of therapy intensification in order to make anticancer treatment more effective is still being investigated. The study aimed to estimate the impact of the chemotherapy dose levels and treatment duration on the risk for dental development disturbance. The clinical examination and OPG analysis were carried out in 37 cancer survivors and germ agenesis, microdontia, size reduction, taurodontism, root and enamel abnormalities were identified. An analysis of anticancer treatment was carried out separately for vincristine (VCR), doxorubicin (DXR), cyclophosphamide (CP), etoposide (VP-16), carboplatin (CBDCA) and actinomycin D (ACTD) recipients in terms of treatment duration and drug doses administered. Individuals aged between three years and ten months, and seven years and four months, at diagnosis presented with no severe dental abnormalities, regardless of treatment duration and increasing cytotoxic drug doses. The largest number of abnormalities per one person was noted in the survivors treated with the highest single doses of VCR, DXR, CP and ACTD. No similar observation was made in the cases of cumulative and weekly doses analyzed. Moreover, there were no significant differences between the mean number of abnormalities across all the drug groups.

Abstract
Survival following childhood cancer has increased considerably. In an observational cross-sectional study, we assessed the prevalence of dental developmental anomalies (DDA) among childhood cancer survivors according to types of anticancer treatment. Permanent teeth were examined clinically and radiographically in 121 adolescents with a history of childhood malignancies, to identify DDA, namely hypomineralization or hypoplasia, microdontia, root changes and hypodontia. DDA were observed in 56/121 individuals (46%), in 309/3388 teeth (9%). Hypomineralization or hypoplasia of enamel appeared in 21 (17%) patients. Altered root development appeared in 26 patients and hypodontia affected 13 (10%). Dental anomalies were observed in 36 (43%) individuals who received chemotherapy and not radiation, in 20 (52%) who received radiotherapy, and in 15 (60%) of those who received head and neck radiotherapy. Among patients who received only chemotherapy, young age (6 years or younger) was associated with a higher number of malformed teeth. In conclusion, antineoplastic treatment that combines chemotherapy and radiotherapy appears to increase the risk of DDA. Radiation to the head and neck area was shown to particularly increase the risk of DDA. No specific chemotherapy agent was found to be associated more than the others with DDA.

An ex vivo organ culture screening model revealed that low temperature conditions prevent side effects of anticancer drugs. Sci Rep 2022; 12:3093.

Abstract
Development of chemotherapy has led to a high survival rate of cancer patients; however, the severe side effects of anticancer drugs, including organ hypoplasia, persist. To assume the side effect of anticancer drugs, we established a new ex vivo screening model and described a method for suppressing side effects. Cyclophosphamide (CPA) is a commonly used anticancer drug and causes severe side effects in developing organs with intensive proliferation, including the teeth and hair. Using the organ culture model, we found that treatment with CPA disturbed the growth of tooth germs by inducing DNA damage, apoptosis and suppressing cellular proliferation and differentiation. Furthermore, low temperature suppressed CPA-mediated inhibition of organ development. Our ex vivo and in vitro analysis revealed that low temperature impeded Rb phosphorylation and caused cell cycle arrest at the G1 phase during CPA treatment. This can prevent the CPA-mediated cell damage of DNA replication caused by the cross-linking reaction of CPA. Our findings suggest that the side effects of anticancer drugs on organ development can be avoided by maintaining the internal environment under low temperature.

Abstract
PURPOSE To investigate oral and dental late effects in survivors of childhood brain tumors medulloblastoma (MB) and central nervous system supratentorial primitive neuroectodermal tumor (CNS-PNET). METHODS This cross-sectional study assessed oral and dental late effects in MB/CNS-PNET survivors treated before 20 years of age, and with a minimum of 2 years since treatment. Participants went through an oral and radiographic examination. We assessed oral status using the decayed-missing-filled index (DMFT), oral dryness, maximum mouth opening (MMO), fungal infection, and registration of dental developmental disturbances (DDD) in the form of hypodontia, microdontia, and enamel hypoplasia. RESULTS The 46 participants' mean age at enrolment was 27 ± 12.8 years and at treatment 8.5 ± 5.2 years, and the mean time since treatment was 18.9 ± 12 years. Over a third (35%) of survivors had reduced mouth opening (mean 29.3 ± 5.6 mm (range 16-35)). A significantly lower MMO was found in individuals treated ≤ 5 years compared to survivors treated > 5 years (p = 0.021). One or more DDD were registered in 30.4% of the survivors, with a significantly higher prevalence in individuals treated ≤ 5 years (p < 0.001). Hypodontia was the most prevalent type of DDD. There was no difference in DMFT score in relation to age at treatment. Oral dryness was not frequently reported or observed in these survivors. CONCLUSION Survivors of childhood MB/CNS-PNET are at risk of oral and dental late effects including reduced mouth opening and DDD. The risk is highest in survivors treated before the age of 5.

Abstract
BACKGROUND Dental anomalies are common late side effects of childhood cancer therapy and may lead to anatomical, functional, and aesthetic sequelae. AIM The study aimed to record dental late effects of antineoplastic treatment and associate them with disease and treatment characteristics in order to identify possible risk factors. DESIGN Orthopantomograms of 70 survivors aged 4-21 years, who were treated at ages 0-10 years for any type of malignancy and completed antineoplastic treatment at least one year before, were examined. Incidence of developmental disturbances was recorded. Their severity was calculated, and odds ratios for the development of severe defects were estimated. RESULTS Root defects presented in 62% of the participants, with impaired root growth being the most common (58%). Increased incidence was associated with combination treatment protocols, irradiation to the head and neck region, and administration of antimetabolites, steroids, and vincristine. Mean DeI value was 17.46 with risk factors for the development of severe root defects being diagnosis of acute lymphoblastic leukemia, combination treatment protocols, administration of cyclophosphamide and steroids, and hemopoietic stem cell transplantation. CONCLUSIONS Root defects are common among childhood cancer survivors, with their incidence and severity being affected by multiple disease and treatment characteristics.

Abstract
Simple Summary We aimed to identify the prevalence of and independent risk factors for dental and oral problems in childhood cancer survivors (CCSs). This cross-sectional study is part of the Dutch Childhood Cancer Survivor Study (DCCSS) LATER 2. Our study included survey data on 154 CCSs, on whom information from dentists on oral health data was received (71.3%). In total, 36.3% of survivors were reported to have at least one dental developmental disorder (DDD). The most prevalent DDDs were short-root anomaly (14.6%), agenesis (14.3%), and microdontia (13.6%). Risk factors for at least one DDD were younger age at diagnosis (<3 years vs. 5+ years) and dose-dependent alkylating agent therapy. This study provides more insight into risk factors for oral health problems in Dutch CCSs. This information is essential in order to improve early detection, prevention, and dental care of oral health problems in CCSs. Abstract Objectives: The aim of this study was to identify the prevalence of and independent risk factors for long-term effects of childhood cancer treatment on the dentition and oral health in childhood cancer survivors (CCSs). Methods: This cross-sectional study is part of the Dutch Childhood Cancer Survivor Study (DCCSS) LATER 2. CCSs were diagnosed with cancer between 1963 and 2001. This study focuses on survey data of 154 CCSs on whom information about their oral health was received from their dentists (71.3%). Descriptive statistics and univariable and multivariable Poisson regression analyses were performed to determine the association between treatment characteristics and oral health data. Results: Of the study group, 36.3% had at least one DDD. The most prevalent DDDs were short-root anomaly (14.6%), agenesis (14.3%), and microdontia (13.6%). Risk factors for at least one DDD were younger age at diagnosis (<3 years) and dose-dependent alkylating agent therapy. Conclusions: This study provides more insight into risk factors for oral health problems in Dutch CCSs. This information is essential in order to improve early detection, prevention, dental care, and quality of life. Further studies are needed in order to better define dose-related radiotherapy exposure of the developing teeth in correlation with oral health problems.

Abstract
BACKGROUND Childhood cancer survivors show a variety of late adverse effects on dental health. The purpose of this study was to examine the prevalence and severity of dental abnormalities in permanent dentition in childhood leukemia survivors. MATERIALS AND METHODS Retrospective analysis of panoramic radiographs was performed for 178 childhood leukemia survivors aged below 17 years at the time of diagnosis. Sex, age at diagnosis, interval between ALL diagnosis and the follow-up radiograph, treatment protocol, and risk grouping were recorded. Abnormalities of tooth development and defect index were used to assess the frequency and severity of dental abnormalities. RESULTS One hundred eight (61%) patients had no dental abnormalities at follow-up examination at a median of 6.1 years after diagnosis. Microdontia was more frequent in children under 6 years of age at the time of diagnosis (5.7% vs. 0.6%, p < .001). Significant differences were noted between distinct ALL treatment protocols with more common microdontia in patients treated according to the NOPHO ALL2008 protocol. Tooth agenesis was more frequent in patients that underwent therapy according to high-risk arms compared to intermediate- or standard-risk arms (3.8% vs. 1.4%, p = .01). Patients under 6 years of age at diagnosis had a significantly higher average defect index score than older patients (7.0 vs. 2.8, p = .01). CONCLUSIONS Children and adolescents who received ALL treatment were at risk for dental damage. Young age and high-intensity therapy were associated with the severity of dental abnormalities.

[PMID: 32854493 PMCID: PMC7812002 DOI: 10.4143/crt.2020.275] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2020] [Accepted: 08/22/2020] [Indexed: 02/02/2023] Open
Abstract
PURPOSE The study aimed to assess the differences in dental maturation between childhood cancer survivors and healthy children. Materials and Methods Fifty-nine cancer patients including 16 (27.1%) girls and 43 (72.8%) boys, aged between 4 and 16 years, underwent dental and radiographic examinations. The mean duration of anticancer therapy was 16.8 months (range, 1 to 47 months), and 4.6 years (range, 8 to 123 months) had passed since the termination of disease. The control group consisted of 177 panoramic radiographs of age- and sex-matched healthy individuals. Dental age (DA) was estimated with Demirjian's scale and delta age, i.e., DA-chronological age (CA), was used to compare groups. RESULTS The DA of cancer survivors was accelerated by almost 1 year compared to their CA (9.9±3.1 vs. 8.9±2.8, p=0.040). The greatest difference was observed among patients with brain tumor: delta (DA-CA) was 2.2±1.1 years. Among all cancer patients, only children with familial adenomatous polyposis (FAP)-associated hepatoblastoma (HP) demonstrated delayed DA, with regard to both other cancer survivors (p=0.011) and healthy patients (p=0.037). All four patients with HP suffered from FAP, and three of them had documented adenomatous polyposis coli (APC) genes mutation. The DA of cancer patients having teeth with short roots was significantly greater than that of the cancer survivors without this anomaly (12.8±3.2 vs. 9.0±2.4, p < 0.001). CONCLUSION DA in children may be altered by cancer disease.

Abstract
BACKGROUND This systematic review summarizes the prevalence of dental defects after chemo and radiation therapy and correlates the findings with specific characteristics of each treatment modality. METHODS Database search was performed for studies reporting dental late effects of chemo and radiation therapy. After data extraction and risk of bias assessment, prevalence of crown and root defects was assessed. Correlations between each defect and the characteristics of the antineoplastic treatment were performed. RESULTS Sixteen nonrandomized studies were included, yielding a total of 1300 patients with a mean age at diagnosis of 4.5 years. Results reported that root defects were more common than crown defects. The most common root defect was impaired root growth and microdontia the most common crown defect. Age, radiation dose and field were statistically associated with higher prevalence of dental defects. CONCLUSION Defects were associated with combination of chemotherapy and radiotherapy, as used in current therapeutic antineoplastic modalities.

Clinical ascertainment of health outcomes in Asian survivors of childhood cancer: a systematic review. J Cancer Surviv 2019; 13:374-396. [PMID: 31055708 PMCID: PMC6548762 DOI: 10.1007/s11764-019-00759-9] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2018] [Accepted: 04/05/2019] [Indexed: 12/29/2022]
Abstract
Purpose Survivorship in children with cancer comes at a cost of developing chronic treatment-related complications. Yet, it is still an under-researched area in Asia, which shares the largest proportion of the global childhood cancer burden given its vast population. This systematic review summarizes existing literature on clinically ascertained health outcomes in Asian survivors of childhood cancer. Methods A search was conducted on Ovid Medline and EMBASE for studies that focused on survivors of childhood cancer from countries in East and Southeast Asia; adopted post-treatment clinical ascertainment of organ-specific toxicities or/and secondary malignancy. Studies were excluded if health outcomes were assessed during the acute treatment. Results Fifty-nine studies, enrolling a total of 13,442 subjects, were conducted on survivors of leukemia (34%), CNS tumor (14%), and cohorts of survivors with heterogeneous cancer diagnoses (52%). The studies used different medical evaluation methods to assess cardiovascular (15%), metabolic and infertility (32%), and neurological/neurocognitive (20%) outcomes in survivors. The collective findings suggest potential differences in the prevalence of certain late effects (e.g., secondary malignancy and obesity) among Asian and non-Asian populations, which may reflect differences in treatment regimens, practice, genetic variations, or/and socioeconomic disparity. Conclusions We recommend developing collaborative initiatives to build a regional repository of systematically assessed health outcomes and biospecimens to investigate treatment, social-environmental and genetic predictors, and interventions for late effects in this population. Implications for Cancer Survivors The existing types of chronic health problems identified in this review suggest the need for active screening, better access to survivorship care, and promotion of protective health behavior in Asia.

Abstract
PURPOSE OF REVIEW Over 80% of children diagnosed with cancer are now cured. The burgeoning population of survivors of childhood cancer experiences high rates of morbidity and mortality due to 'late-effects' of treatment. These can be defined as any consequence of treatment that persists beyond or develops after the completion of cancer therapy. Awareness of late-effects is critically important for pediatricians and adult providers alike, as late-effects impact children in proximity to cancer treatment, as well as adults many decades removed. This review presents the importance of lifelong follow-up care for survivors, highlights existing screening guidelines, and reviews various models of survivor care. RECENT FINDINGS National and international guidelines have been developed to standardize screening for survivors, and multiple models of survivorship care exist. The optimal model likely depends on individual factors, including the survivor's needs and preferences, as well as local resources. Key strategies for the successful care of survivors include accurate risk-stratification for specific late-effects, individualized screening plans, education of survivors and professionals, clear communication between providers, and well coordinated transition of care across services. SUMMARY Early identification and management of late-effects are important for survivors of childhood cancer. Providers should be familiar with the risks for specific late-effects and have access to screening guidelines. The strengths and weaknesses of care models, along with individual circumstances, should be considered in designing the optimal approach to care for each survivor.
