[PMID: 38323945 DOI: 10.1016/j.ijrobp.2023.12.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Revised: 12/06/2023] [Accepted: 12/15/2023] [Indexed: 02/08/2024]
Abstract
PURPOSE Radiation myelitis (RM) is a rare complication of radiation therapy (RT). The Pediatric Normal Tissue Effects in the Clinic spinal cord task force aimed to identify RT dose effects and assess risk factors for RM in children. Through systematic review, we analyzed RT dose, fraction size, latency between completion of RT and toxicity, chemotherapy use, age when irradiated, and sex. METHODS AND MATERIALS We conducted literature searches of peer-reviewed manuscripts published from 1964 to June 2017 evaluating RM among children. Normality of variables was assessed with Kolmogorov-Smirnov or Shapiro-Wilk tests. Spearman's rank correlation coefficients were used to test correlations between RT dose/fraction size and latency between RT and development of toxicity. RESULTS Of 1329 identified and screened reports, 144 reports were fully reviewed and determined to have adequate data for analysis; 16 of these reports had a total of 33 cases of RM with a median age of 13 years (range, 0.2-18) at the time of RT. The most common primary tumor histologies were rhabdomyosarcoma (n = 9), medulloblastoma (n = 5), and Hodgkin lymphoma (n = 2); the most common chemotherapy agents given were vincristine (n = 15), intrathecal methotrexate (n = 12), and intrathecal cytarabine (n = 10). The median RT dose and fraction size were 40 Gy (range, 24-57.4 Gy) and 1.8 Gy (range, 1.3-2.6 Gy), respectively. RT dose resulting in RM in patients who also received chemotherapy was lower than in those not receiving chemotherapy (mean 39.6 vs 49.7 Gy; P = .04). There was no association of age with RT dose. The median latency period was 7 months (range, 1-29). Higher RT dose was correlated with longer latency periods (P = .03) to RM whereas sex, age, fraction size, and chemotherapy use were not. Two of 17 patients with adequate follow-up recovered from RM; unfortunately, it was fatal in 6 of 15 evaluable patients. Complication probability modeling was not possible because of the rarity of events. CONCLUSIONS This report demonstrates a relatively short latency from RT (with or without chemotherapy) to RM and a wide range of doses (including fraction sizes) associated with RM. No apparent association with age at the time of RT could be discerned. Chemotherapy appears to reduce spinal cord tolerance. Recovery from RM is rare, and it is often fatal.

Relapsed Medulloblastoma in Pre-Irradiated Patients: Current Practice for Diagnostics and Treatment. Cancers (Basel) 2021; 14:126. [PMID: 35008290 PMCID: PMC8750207 DOI: 10.3390/cancers14010126] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Revised: 12/23/2021] [Accepted: 12/24/2021] [Indexed: 02/07/2023] Open
Abstract
Relapsed medulloblastoma (rMB) accounts for a considerable, and disproportionate amount of childhood cancer deaths. Recent advances have gone someway to characterising disease biology at relapse including second malignancies that often cannot be distinguished from relapse on imaging alone. Furthermore, there are now multiple international early-phase trials exploring drug-target matches across a range of high-risk/relapsed paediatric tumours. Despite these advances, treatment at relapse in pre-irradiated patients is typically non-curative and focuses on providing life-prolonging and symptom-modifying care that is tailored to the needs and wishes of the individual and their family. Here, we describe the current understanding of prognostic factors at disease relapse such as principal molecular group, adverse molecular biology, and timing of relapse. We provide an overview of the clinical diagnostic process including signs and symptoms, staging investigations, and molecular pathology, followed by a summary of treatment modalities and considerations. Finally, we summarise future directions to progress understanding of treatment resistance and the biological mechanisms underpinning early therapy-refractory and relapsed disease. These initiatives include development of comprehensive and collaborative molecular profiling approaches at relapse, liquid biopsies such as cerebrospinal fluid (CSF) as a biomarker of minimal residual disease (MRD), modelling strategies, and the use of primary tumour material for real-time drug screening approaches.

Young Adult Populations Face Yet Another Barrier to Care With Insurers: Limited Access to Proton Therapy. Int J Radiat Oncol Biol Phys 2021; 110:1496-1504. [PMID: 33677051 DOI: 10.1016/j.ijrobp.2021.02.049] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2021] [Revised: 02/11/2021] [Accepted: 02/23/2021] [Indexed: 11/20/2022]
Abstract
PURPOSE Young patients, including pediatric, adolescent, and young adult (YA) patients, are most likely to benefit from the reduced integral dose of proton beam radiation therapy (PBT) resulting in fewer late toxicities and secondary malignancies. This study sought to examine insurance approval and appeal outcomes for PBT among YA patients compared with pediatric patients at a large-volume proton therapy center. METHODS AND MATERIALS We performed a cross-sectional cohort study of 284 consecutive patients aged 0 to 39 years for whom PBT was recommended in 2018 through 2019. Pediatric patients were defined as aged 0 to 18 years and YA patients 19 to 39 years. Rates of approval, denials, and decision timelines were calculated. Tumor type and location were also evaluated as factors that may influence insurance decisions. RESULTS A total of 207 patients (73%) were approved for PBT at initial request. YA patients (n = 68/143, 48%) were significantly less likely to receive initial approval compared with pediatric patients (n = 139/141; 99%) (P < .001). Even after 47% (n = 35 of 75) of the PBT denials for YA patients were overturned, YAs had a significantly lower final PBT approval (72% vs pediatric 99%; P < .001). The median wait time was also significantly longer for YA patients (median, 8 days; interquartile range [IQR] 3-17 vs median, 2 days; IQR, 0-6; P < .001). In those patients requiring an appeal, the median wait time was 16 days (IQR, 9-25). CONCLUSION Given the decades of survivorship of YA patients, PBT is an important tool to reduce late toxicities and secondary malignancies. Compared with pediatric patients, YA patients are significantly less likely to receive insurance approval for PBT. Insurance denials and subsequent appeal requests result in significant delays for YA patients. Insurers need to re-examine their policies to include expedited decisions and appeals and removal of arbitrary age cutoffs so that YA patients can gain easier access to PBT. Furthermore, consensus guidelines encouraging greater PBT access for YA may be warranted from both medical societies and/or AYA experts.

Abstract
We retrospectively analyzed endocrine late effects in 81 childhood cancer survivor (CCS) patients who had been referred to our endocrinology department in Chiba Children's Hospital between January 1, 2008 and December 31, 2016. Among 69 eligible patients (33 male, 36 female), endocrine late effects were identified in 56 patients (81.1%). The median age at the last visit to our endocrinology department was 17.4 years (range: 7.1-35.3 years). The most common primary cancer was acute lymphoblastic leukemia (22 patients, 31.8%). Forty-four patients (64%) were treated using radiation therapy. A primary brain tumor and high doses (≥6 g/m2) of cyclophosphamide were significantly associated with growth hormone deficiency (GHD). Our present study suggests that high doses of cyclophosphamide is a risk factor for GHD. Adult heights and pubertal growth spurts of patients treated with radiation therapy were significantly lower than patients not treated with radiation therapy. Our retrospective study reconfirmed that hematopoietic stem cell transplantation and chronic graft versus host disease (GVHD) were associated with elevated risks of primary hypothyroidism. However, it is unclear whether GVHD induces thyroid dysfunction. Gonadal radiation and busulfan were associated with primary hypogonadism as reported in previous studies. We found high doses of cyclophosphamide to be involved in pituitary disorders. We suggest that pediatric endocrinologists should discuss the potential effects of radiation therapy on adult height and pubertal growth spurt in CCS patients. Moreover, patients who have been treated with high doses of cyclophosphamide or have chronic GVHD require long-term follow-up for endocrine late effects.

Abstract
Transverse myelitis (TM) includes a pathobiologically heterogeneous syndrome characterized by acute or subacute spinal cord dysfunction resulting in paresis, a sensory level, and autonomic (bladder, bowel, and sexual) impairment below the level of the lesion. Etiologies for TM can be broadly classified as parainfectious, paraneoplastic, drug/toxin-induced, systemic autoimmune disorders, and acquired demyelinating diseases. We discuss the clinical evaluation, workup, and acute and long-term management of patients with TM. Additionally, we briefly discuss various disease entities that may cause TM and their salient distinguishing features, as well as disorders that may mimic TM.

Abstract
Neurologic dysfunction is a common side effect of many chemotherapy drugs. For several agents neurotoxicity is common, severe, and can be dose limiting. As the list of newer chemotherapy agents and systemic targeted therapies grows, so does the number and variety of potential neurotoxicities. This article reviews the clinical features of chemotherapy-induced syndromes involving the central and peripheral nervous systems.

Neuropathic pain referrals to a multidisciplinary pediatric cancer pain service. Pain Manag Nurs 2012; 15:126-31.

Abstract
Neuropathic pain (NP) in children with cancer is not well characterized. In a retrospective review of patient data from a 3.5-year period, we describe the prevalence of NP and the characteristics, duration of follow-up, and interventions provided for NP among patients referred to a pediatric oncology center's pain management service. Fifteen percent (66/439) of all referrals to our pain service were for NP (56/323 patients [17%]; 34 male, 22 female). The NP patient group had 1,401 clinical visits (778 inpatient visits [55.5%] and 623 outpatient visits [44.5%]). Patients with NP had a significantly greater mean number of pain visits per consultation (p = .008) and significantly more days of pain service follow-up (p < .001) than did other patients. The most common cause of NP was cancer treatment rather than the underlying malignancy. Pharmacologic management of NP was complex, often comprising three medications. Nonpharmacologic approaches were used for 57.6% of NP referrals. Neuropathic pain is less frequently encountered than non-NP in children with cancer; nevertheless, it is more difficult to treat, requiring longer follow-up, more clinical visits, complex pharmacologic management, and the frequent addition of nonpharmacologic interventions.
