Total-Body Irradiation Is Associated With Increased Incidence of Mesenchymal Neoplasia in a Radiation Late Effects Cohort of Rhesus Macaques (Macaca mulatta). Int J Radiat Oncol Biol Phys 2022; 113:661-674. [PMID: 35361520 PMCID: PMC9250621 DOI: 10.1016/j.ijrobp.2022.02.019] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2021] [Revised: 02/04/2022] [Accepted: 02/13/2022] [Indexed: 11/21/2022]
Abstract
PURPOSE Cancer is a severe delayed effect of acute radiation exposure. Total-body irradiation has been associated with an increased risk of solid cancer and leukemia in Japanese atomic bomb survivors, and secondary malignancies, such as sarcoma, are a serious consequence of cancer radiation therapy. The radiation late effects cohort (RLEC) of rhesus macaques (Macaca mulatta) is a unique resource of more than 200 animals for studying the long-term consequences of total-body irradiation in an animal model that closely resembles humans at the genetic and physiologic levels. METHODS AND MATERIALS Using clinical records, clinical imaging, histopathology, and immunohistochemistry, this retrospective study characterized the incidence of neoplasia in the RLEC. RESULTS Since 2007, 61 neoplasms in 44 of 239 irradiated animals were documented (18.4% of the irradiated population). Only 1 neoplasm was diagnosed among the 51 nonirradiated controls of the RLEC (2.0%). The most common malignancies in the RLEC were sarcomas (38.3% of diagnoses), which are rare neoplasms in nonirradiated macaques. The most common sarcomas included malignant nerve sheath tumors and malignant glomus tumors. Carcinomas were less common (19.7% of diagnoses), and consisted primarily of renal cell and hepatocellular carcinomas. Neoplasia occurred in most major body systems, with the skin and subcutis being the most common site (40%). RNA analysis showed similarities in transcriptional profiles between RLEC and human malignant nerve sheath tumors. CONCLUSIONS This study indicates that total-body irradiation is associated with an increased incidence of neoplasia years following irradiation, at more than double the incidence described in aging, nonirradiated animals, and promotes tumor histotypes that are rarely observed in nonirradiated, aging rhesus macaques.

A Review of Acute and Long-Term Neurological Complications Following Haematopoietic Stem Cell Transplant for Paediatric Acute Lymphoblastic Leukaemia. Front Pediatr 2021; 9:774853.

Abstract
Despite advances in haematopoietic stem cell transplant (HSCT) techniques, the risk of serious side effects and complications still exists. Neurological complications, both acute and long term, are common following HSCT and contribute to significant morbidity and mortality. The aetiology of neurotoxicity includes infections and a wide variety of non-infectious causes such as drug toxicities, metabolic abnormalities, irradiation, vascular and immunologic events and the leukaemia itself. The majority of the literature on this subject is focussed on adults. The impact of the combination of neurotoxic drugs given before and during HSCT, radiotherapy and neurological complications on the developing and vulnerable paediatric and adolescent brain remains unclear. Moreover, the age-related sensitivity of the nervous system to toxic insults is still being investigated. In this article, we review current evidence regarding neurotoxicity following HSCT for acute lymphoblastic leukaemia in childhood. We focus on acute and long-term impacts. Understanding the aetiology and long-term sequelae of neurological complications in children is particularly important in the current era of immunotherapy for acute lymphoblastic leukaemia (such as chimeric antigen receptor T cells and bi-specific T-cell engager antibodies), which have well-known and common neurological side effects and may represent a future treatment modality for at least a fraction of HSCT-recipients.

Abstract
Introduction Total body irradiation (TBI) is a part of the conditioning regimen for bone marrow transplant.At the Royal Marsden (Sutton, UK) and Rigshospitalet (Copenhagen, Denmark), we introduced a step and shoot IMRT (SS IMRT) technique for TBI. This technique requires no equipment other than that used to deliver other external beam radiation. In this paper, we describe this technique and report on data from the two clinics. Materials and methods The patients were positioned supine, supported by vacuum bag(s). The entire body of the patients were CT scanned with 5 mm slices. Multiple multi-leaf collimator (MLC) defined fields were used.In-vivo dosimetry was performed at the Royal Marsden for 113 patients.Calculated doses for 18 adult and 4 paediatric patients from Rigshospitalet were extracted. Results The in-vivo data from the Royal Marsden showed that the mean TLD measured dose difference was -1.9% with a standard deviation of 4.5%.SS IMRT plans for 22 patients from Rigshospitalet resulted in mean doses to the brain, lungs and kidneys all within the range of 11.1-11.8 Gy, while the V(12 Gy) was below 5% for the brain, 2% for the lungs and 0% for the kidneys. Discussion SS IMRT is feasible for TBI and can deliver targeted doses to the organs at risk.

Abstract
Many immunosuppressive drugs are associated with an increased risk of B-cell lymphoma, squamous cell carcinoma, and Kaposi sarcoma. Thirteen immunosuppressive drugs have been tested in 2-year carcinogenicity studies (abatacept; azathioprine; busulfan; cyclophosphamide; cyclosporine; dexamethasone; everolimus; leflunomide; methotrexate; mycophenolate mofetil; prednisone; sirolimus; and tacrolimus) and in additional models including neonatal and genetically modified mice; chemical, viral, ultraviolet, and ionizing radiation co-carcinogenesis, and in models with transplanted tumor cells. The purpose of this review is to outline the mechanisms by which immunosuppressive drugs can influence neoplasia, to summarize the available preclinical data on the 13 drugs, and to critically review the performance of the models. A combination of primary tumor and metastasis assays conducted with transplanted cells may provide the highest value for hazard identification and can be applied on a case-by-case basis. However, for both small molecules and therapeutic proteins, determining the relative risk to patients from preclinical data remains problematic. Classifying immunosuppressive drugs based on their mechanism of action and hazard identification from preclinical studies and a prospective pharmacovigilance program to monitor carcinogenic risk may be a feasible way to manage patient safety during the clinical development program and postmarketing.

Abstract
The concept of radiation therapy for the treatment of benign diseases refers to the use of moderate to high-energy ionising radiation as part of the treatment of non-malignant, but not necessarily harmless, diseases. The usefulness of radiation therapy, based on the anti-inflammatory properties of ionising radiation, has long been known. Apart from the treatment of intracranial benign tumours, such as meningiomas and neurinomas, the prevention of cardiovascular restenosis or treatment of skeletal degenerative diseases are, without doubt, the main fields of action for radiation therapy in benign conditions. Nonetheless, many other non-cancer entities may benefit from ionising radiation therapy treatment. The purpose of this review is to highlight and update indications for treatment with radiation therapy in benign conditions, focusing on skeletal degenerative processes, vascular conditions and soft tissue diseases.

Abstract
Concern for risk of radiation-induced cancer is growing with the increasing number of cancer patients surviving long term. This study examined data on radiation transformation of mammalian cells in vitro and on the risk of an increased cancer incidence after irradiation of mice, dogs, monkeys, atomic bomb survivors, occupationally exposed persons, and patients treated with radiation. Transformation of cells lines in vitro increased linearly with dose from approximately 1 to approximately 4-5 Gy. At <0.1 Gy, transformation was not increased in all studies. Dose-response relationships for cancer incidence varied with mouse strain, gender and tissue/organ. Risk of cancer in Macaca mulatta was not raised at 0.25-2.8 Gy. From the atomic bomb survivor study, risk is accepted as increasing linearly to 2 Sv for establishing exposure standards. In irradiated patients, risk of cancer increased significantly from 1 to 45 Gy (a low to a high dose level) for stomach and pancreas, but not for bladder and rectum (1-60 Gy) or kidney (1-15 Gy). Risk for several organs/tissues increased substantially at doses far above 2 Gy. There is great heterogeneity in risk of radiation-associated cancer between species, strains of a species, and organs within a species. At present, the heterogeneity between and within patient populations of virtually every parameter considered in risk estimation results in substantial uncertainty in quantification of a general risk factor. An implication of this review is that reduced risks of secondary cancer should be achieved by any technique that achieved a dose reduction down to approximately [corrected] 0.1 Gy, i.e. dose to tissues distant from the target. The proportionate gain should be greatest for dose decrement to less than 2 Gy.

Abstract
Nuclear warfare research and treatment of radiation accident victims uncovered the potential of hemopoietic stem cell transplants. Prior to transplantation of hemopoietic stem cells patients receive "conditioning" agents: high-dose total-body irradiation and/or high-dose chemotherapy. High-dose conditioning causes at least 20% procedure-related mortality. Recent efforts to reduce procedure-related mortality by the use of low-dose conditioning included low-dose total-body irradiation, immunosuppressive agents, and the replacement of high-dose chemotherapy by donor lymphocytes for graft-vs-tumor effects. Procedure-related mortality remains high (10-30%). Tumor recurrence at 1 year is over 50%. In this review, the aims of conditioning (creation of space, prevention of hemopoietic stem cell rejection, eradication of immune memory, and eradication of tumor cells) are reexamined in those patient and animal studies that explore quantitative and mechanistic conditioning issues. Translational experimental animal models provide the best opportunities for the development of less toxic conditioning agents for human patients and require an analysis of the consequences of the effects of new conditioning agents on host-vs-graft as well as graft-vs-host reactions. Total-body irradiation or other forms of radiation create space, prevent rejection of histocompatible stem cells, and can eliminate immune memory to autoimmune antigens at modest, nontoxic doses. The transplantation of histoincompatible stem cells and the eradication of large loads of tumor cells remain problematic. The therapeutic index of allogeneic stem cell transplants will increase if new conditioning agents are targeted only to those host tissues that need conditioning: hemopoietic system, immune system, and tumor masses. Radiolabeled immunoglobulins are among the most promising new, low-toxicity conditioning agents.

Abstract
In the early sixties, studies have been performed at the TNO-Institutes for Health Research on acute effects of high dose total body irradiation (TBI) with X-rays and fission neutrons in Rhesus monkeys and the protective effect of autologous bone marrow transplantation (BMT). The surviving animals of this study were kept to investigate late radiation effects, ie, tumorigenesis. TBI in combination with chemotherapy, followed by rescue with BMT is increasingly used for the treatment of hematological malignancies and refractory autoimmune disease. The risk of radiation carcinogenesis after this treatment is of growing concern in man. Studies on tumor induction in nonhuman primates are of relevance in this context since the response of this species to radiation does not differ much from that in man. The group of long-term surviving monkeys comprised nine neutron irradiated animals (average total body dose 3A Gy, range 2.3-4.4 Gy) and 20 X-irradiated monkeys (average total body dose 7.1 Gy, range 2.8-8.6 Gy). A number of 21 age-matched nonirradiated Rhesus monkeys served as a control-group. All animals wereregularly screened for the occurrence of tumors. Complete necropsies were performed after natural death or euthanasia. At postirradiation intervals of 4-21 years an appreciable number of malignant tumors was observed. In the neutron irradiated group eight out of nine animals died with 1 or more malignant tumors. In the X-irradiated group this fraction was 10 out of 20. The tumors in the control group, in seven out of 21 animals, appeared at much older age compared with those in the irradiated cohorts. The histogenesis of the malignant tumors was diverse, as was the case for benign tumors. The observed shortening of latency periods and life span, as well as, the increase of mean number of tumors per tumor bearing animal for benign neoplasms parallels the trend observed for malignant tumors. The results of this study were compared to other radiation late effects after TBI followed by different BMT treatment modalities in Rhesus monkeys. The observation that the carcinogenic risk of TBI in the Rhesus monkeys is similar to that derived from the studies of the Japanese atomic bomb survivors and the increase of the risk by a factor of 8 emphasizes the need for regular screening for secondary radiation-induced tumors in long-term surviving patients after TBI followed by BMT.

Abstract
PURPOSE The aim of this retrospective analysis was to find out whether low-dose radiation, which is used in the treatment of Graves' ophthalmopathy, could cause radiation-induced cancer, which would in turn adversely affect the survival of the irradiated population and cause an increase in the cancer-specific death rate. METHODS AND MATERIALS From 1963 to 1978, 250 patients received bilateral orbital irradiation for a progressive Graves' ophthalmopathy. Median age was 49 years. Overall survival and causes of death were evaluated with the help of patients still living, registration offices, medical records, referring physicians, and relatives. Survival curves were calculated with the Kaplan-Meier method. The outcome for each patient was compared with data from life tables regarding gender, age, and calendar period-specific person-years at risk. In addition, treatment outcome for living patients was evaluated with a questionnaire. RESULTS After a median follow-up of 31 years, 102 patients are still alive, 123 patients have died, and 25 patients have been lost to follow-up. The 10-year, 20-year, and 30-year survival rates were 89%, 68%, and 49%, compared with the age-adapted survival rate of the normal population of 92%, 76%, and 52%. Evaluation of cancer-specific survival was possible in 166 cases. The 10-year, 20-year, and 30-year cancer-specific survival rates were 98%, 92%, and 88%, compared with 97%, 93%, and 87% in the normal population. Treatment response was evaluable in 94 cases. A complete response was reported in 41 patients, a partial response in 39 patients, and no change in 14 patients. CONCLUSIONS No significant evidence of radiation-induced cancer death was seen in this small cohort of patients treated with radiotherapy for Graves' ophthalmopathy. The long-term treatment results seem to be satisfactory. Studies with greater numbers of patients are necessary to examine the risks and benefits more precisely.

Abstract
In view of the probable carcinogenic risk due to the irradiation of Graves' ophthalmopathy in young patients the effective dose was assessed for two geometries. Adjusting the field to the conical outline of the orbit resulted in appreciable reduction in dose to uninvolved areas such as brain and bone marrow. In Leiden and in Essen the initial target dose was 20 Gy in 10 fractions of 2 Gy. Since 1996 the target dose in Essen was lowered to 10 fractions of 1.6 Gy with equal positive results. The combined effect of field optimization and 20% reduction in target dose has lowered the effective dose from 65 to 34 mSv. The attributable lifetime risk for fatal malignancies of 0.3% as a population average will be considerably reduced when the exposure occurs at older age.
