Abstract
We report the results of a Phase I radiation dose escalation study using an yttrium-90 (90Y) labelled anti-CD66 monoclonal antibody given with standard conditioning regimen for patients receiving haematopoietic stem cell transplants for myeloid leukaemia or myeloma. The 90Y-labelled anti-CD66 was infused prior to standard conditioning. In total, 30 patients entered the trial and 29 received 90Y-labelled mAb, at infused radiation activity levels of 5, 10, 25, or 37.5 megaBequerel (MBq)/kg lean body weight. A prerequisite for receiving the 90Y-labelled mAb was favourable dosimetry determined by single-photon emission computerised tomography (SPECT) dosimetry following administration of indium-111 (111In) anti-CD66. Estimated absorbed radiation doses delivered to the red marrow demonstrated a linear relationship with the infused activity of 90Y-labelled mAb. At the highest activity level of 37.5 MBq/kg, mean estimated radiation doses for red marrow, liver, spleen, kidneys and lungs were 24.6 ± 5.6 Gy, 5.8 ± 2.7 Gy, 19.1 ± 8.0 Gy, 2.1 ± 1.1 and 2.2 ± 0.9, respectively. All patients engrafted, treatment-related mortality 1-year post-transplant was zero. Toxicities were no greater than those anticipated for similar conditioning regimens without targeted radiation. The ability to substantially intensify conditioning prior to haematopoietic stem cell transplantation without increasing toxicity warrants further testing to determine efficacy. clinicaltrials.gov identifier: NCT01521611.

Pulmonary Toxicity After Total Body Irradiation - Critical Review of the Literature and Recommendations for Toxicity Reporting. Front Oncol 2021; 11:708906. [PMID: 34513689 PMCID: PMC8428368 DOI: 10.3389/fonc.2021.708906] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2021] [Accepted: 07/28/2021] [Indexed: 12/12/2022] Open
Abstract
INTRODUCTION Total body irradiation is an effective conditioning regimen for allogeneic stem cell transplantation in pediatric and adult patients with high risk or relapsed/refractory leukemia. The most common adverse effect is pulmonary toxicity including idiopathic pneumonia syndrome (IPS). As centers adopt more advanced treatment planning techniques for TBI, total marrow irradiation (TMI), or total marrow and lymphoid irradiation (TMLI) there is a greater need to understand treatment-related risks for IPS for patients treated with conventional TBI. However, definitions of IPS as well as risk factors for IPS remain poorly characterized. In this study, we perform a critical review to further evaluate the literature describing pulmonary outcomes after TBI. MATERIALS AND METHODS A search of publications from 1960-2020 was undertaken in PubMed, Embase, and Cochrane Library. Search terms included "total body irradiation", "whole body radiation", "radiation pneumonias", "interstitial pneumonia", and "bone marrow transplantation". Demographic and treatment-related data was abstracted and evidence quality supporting risk factors for pulmonary toxicity was evaluated. RESULTS Of an initial 119,686 publications, 118 met inclusion criteria. Forty-six (39%) studies included a definition for pulmonary toxicity. A grading scale was provided in 20 studies (17%). In 42% of studies the lungs were shielded to a set mean dose of 800cGy. Fourteen (12%) reported toxicity outcomes by patient age. Reported pulmonary toxicity ranged from 0-71% of patients treated with TBI, and IPS ranged from 1-60%. The most common risk factors for IPS were receipt of a TBI containing regimen, increasing dose rate, and lack of pulmonary shielding. Four studies found an increasing risk of pulmonary toxicity with increasing age. CONCLUSIONS Definitions of IPS as well as demographic and treatment-related risk factors remain poorly characterized in the literature. We recommend routine adoption of the diagnostic workup and the definition of IPS proposed by the American Thoracic Society. Additional study is required to determine differences in clinical and treatment-related risk between pediatric and adult patients. Further study using 3D treatment planning is warranted to enhance dosimetric precision and correlation of dose volume histograms with toxicities.

Abstract
Stem cell transplantation forms an integral part of the treatment for multiple myeloma. This paper reviews the current role of transplantation and the progress that has been made in order to optimize the success of this therapy. Effective induction chemotherapy is important and a combination regimen incorporating the novel agent bortezomib is now favorable. Adequate induction is a crucial adjunct to stem cell transplantation and in some cases may potentially postpone the need for transplant. Different conditioning agents prior to transplantation have been explored: high-dose melphalan is most commonly used and bortezomib is a promising additional agent. There is no well-defined superior transplantation protocol but single or tandem autologous stem cell transplantations are those most commonly used, with allogeneic transplantation only used in clinical trials. The appropriate timing of transplantation in the treatment plan is a matter of debate. Consolidation and maintenance chemotherapies, particularly thalidomide and bortezomib, aim to improve and prolong disease response to transplantation and delay recurrence. Prognostic factors for the outcome of stem cell transplant in myeloma have been highlighted. Despite good responses to chemotherapy and transplantation, the problem of disease recurrence persists. Thus, there is still much room for improvement. Treatments which harness the graft-versus-myeloma effect may offer a potential cure for this disease. Trials of novel agents are underway, including targeted therapies for specific antigens such as vaccines and monoclonal antibodies.

Abstract
BACKGROUND/AIM In comparison to standard therapy autologous stem cell transplant (ASCT) with high doses mel-phalane has improved treatment of multiple myeloma (MM) patients. The aim of this study was to evaluate the results of treatment of MM patients in our center with ASCTconditioning with melphalane or combining busulphane, cyclophosphamide and melphalane. METHODS We performed 62 ASCT procedures in 47 patients from 1998 till 2008. Single ASCT were performed in 32 patients (68%), after 3-6 cycles of (26% patients. RESULTS Median engraftment was on 12th day. In a 50-month follow-up period 64% patients were alive. The overall response rate (ORR), wich was reached in 38 (80%) patients, was better in the group of patients treated in the early phase of MM. Totally 25 (53%) patients were without progression in a 25-month follow-up period. Twenty patients met criteria for CR + VGPR (very good partial remission), that was 5 patients more than in the period before ASCT. Fourteen (30%) patients died and median time till death was 17 months. CONCLUSION The ASCT perfomed in early phase of MM after V A D induction had a significant influence onthe treatment of MM patients. Reaching CR + VGPR before and after the ASCT is predictive factor for overall survival (OS) or prolongation of period till recidive appears, progression, therapy withdrowal or death.

Abstract
Since its introduction in 1983, high-dose therapy followed by autologous peripheral blood stem cell transplantation is a pillar of the treatment of patients with multiple myeloma. In the last decades, a multitude of clinical trials helped to improve strategies based on high-dose therapy and autologous stem cell transplantation resulting in a continuously prolongation of overall survival of patients. In this chapter we will review the progress, which has been made in order to enhance the mobilisation of autologous stem cells and increase the effectiveness of this treatment.

Abstract
In a recent clinical trial involving patients with metastatic melanoma, immunosuppressive conditioning with fludarabine and cyclophosphamide resulted in a 50% response rate in robust long-term persistence of adoptively transferred T cells. Experimental findings indicate that lymphodepletion prior to adoptive transfer of tumor-specific T lymphocytes plays a key role in enhancing treatment efficacy by eliminating regulatory T cells and competing elements of the immune system ('cytokine sinks'). Newly emerging animal data suggest that more profound lymphoablative conditioning with autologous hematopoetic stem-cell rescue might further enhance treatment results. Here we review recent advances in adoptive immunotherapy of solid tumors and discuss the rationale for lymphodepleting conditioning. We also address safety issues associated with translating experimental animal results of total lymphoid ablation into clinical practice.

Abstract
Multiple myeloma, for all practical purposes, remains an incurable malignancy; however, 5-year survival has improved substantially during the past 30 years. A major contribution to improved outcome is the use of high-dose chemotherapy and stem cell transplantation. This multifaceted approach to therapy requires an understanding of appropriate induction therapy, techniques for stem cell mobilization, appropriate conditioning and supportive care. Also of importance are prognosis, features that predict outcome, the suitability of transplant candidates, and post-transplantation maintenance therapy.

Abstract
Total Body Irradiation (TBI) is one main component in the interdisciplinary treatment of widely disseminated malignancies predominantly of haematopoietic diseases. Combined with intensive chemotherapy, TBI enables myeloablative high dose therapy and immuno-ablative conditioning treatment prior to subsequent transplantation of haematopoietic stem cells: bone marrow stem cells or peripheral blood progenitor stem cells. Jointly prepared by DEGRO and DGMP, the German Society of Radio-Oncology, and the German Association of Medical Physicists, this DEGRO/DGMP-Leitlinie Ganzkoerper-Strahlenbehandlung - DEGRO/DGMP Guideline Whole Body Radiotherapy, summarises the concepts, principles, facts and common methods of Total Body Irradiation and poses a set of recommendations for reliable and successful application of high dose large-field radiotherapy as essential part of this interdisciplinary, multi-modality treatment concept. The guideline is geared towards radio-oncologists, medical physicists, haematooncolo-gists, and all contributing to Whole Body Radiotherapy. To guide centres intending to start or actualise TBI criteria are included. The relevant treatment parameters are defined and a sample of a form is given for reporting TBI to international registries.

Abstract
Autologous stem cell transplantation (SCT) with high-dose melphalan (HDM, 200 mg/m2) is the most effective therapy for multiple myeloma. To determine the feasibility of combining carmustine (300 mg/m2) with HDM, we enrolled 49 patients with previously treated Durie-Salmon stage II/III myeloma (32M/17W, median age 53) on a phase I/II trial involving escalating doses of melphalan (160, 180, 200 mg/m2). The median beta2-microglobulin was 2.5 (0-9.3); marrow karyotypes were normal in 88%. The phase I dose-limiting toxicity was > or =grade 2 pulmonary toxicity 2 months post-SCT. Other endpoints were response rate and progression-free survival (PFS). HDM was safely escalated to 200 mg/m2; treatment-related mortality was 2% and > or =grade 2 pulmonary toxicity 10%. The complete (CR) and near complete (nCR) response rate was 49%. With a median post-SCT follow-up of 2.9 years, the PFS and overall survival (OS) post-SCT were 2.3 and 4.7 years. PFS for those with CR or nCR was 3.1 years while for those with stable disease (SD) it was 1.3 years (P=0.06). We conclude that carmustine can be combined with HDM for myeloma with minimal pulmonary toxicity and a high response rate.

Abstract
We conducted a randomised trial comparing an intensified versus a standard conditioning regimen for high-dose chemotherapy followed by autologous stem-cell transplantation in patients with multiple myeloma. In this study, 56 patients were randomly assigned for high-dose therapy with melphalan 200 mg/m2 or with idarubicin 42 mg/m2, melphalan 200 mg/m2 and cyclophosphamide 120 mg/kg. The primary objective was response rate. Acute toxicity, mainly because of infections, was higher in the intensified treatment arm with a treatment-related mortality of 20% versus 0% in the standard arm. This lead to the early discontinuation of the study. Response rates did not differ significantly between both treatment arms {intensified versus standard: complete response+near complete remission 50% [95% confidence interval (CI) 26-74%] vs. 33% (95% CI 17-55%), partial remission 35% (95% CI 16-61%) vs. 50% (95% CI 30-70%)}. After a follow-up of 5 years, the median time-to-progression and overall survival were not significantly different between both patient groups. Analysis restricted to patients surviving the first 100 d after transplant showed a better outcome for patients with >or=2 bad prognostic risk factors in the intensified treatment arm, however all treatment-related deaths occurred within this group of patients. In conclusion, intensified conditioning for high-dose therapy had intolerably high toxicity without improving outcome in patients with multiple myeloma.

Abstract
PURPOSE To review the characteristics and outcomes of amyloidosis patients treated with high-dose chemotherapy and stem cell reconstitution. SUBJECTS AND METHODS Sixty-six patients with biopsy-proven amyloidosis received transplants between March 1996 and January 2001. All patients had evidence of a clonal plasma cell dyscrasia; those with nonimmunoglobulin forms of amyloidosis were excluded, as were those who had no symptoms of amyloidosis, purpura, carpal tunnel syndrome, or symptomatic multiple myeloma. RESULTS Amyloid was seen clinically in the kidneys (n = 45 patients), heart (n = 32), peripheral nerves (n = 11), and liver (n = 11). A monoclonal protein was found in the serum in 46 patients and in the urine in 57 patients. The median daily urinary protein loss was 4.1 g. Septal thickness, measured by echocardiography, ranged from 7 to 24 mm (median, 12 mm); 8 patients had a septal thickness > or =16 mm. Ten patients received transplants 1 year or more after diagnosis. All patients received melphalan-based chemotherapy; 17 patients were conditioned with total body irradiation. Nine patients required dialysis, 7 of whom died. Treatment-related mortality for stem cell transplantation was 14% (9/66). After a median of 25 months of follow-up after transplantation, the percentage of patients alive with one organ involved was 91% (31 of 34); two organs, 82% (18 of 22); three organs, 33% (3 of 9); and four organs, 0% (0 of 1). Hematologic responses were seen in 33 patients and organ responses in 32 patients. The 2-year actuarial survival of all patients was 70%. CONCLUSION The number of organs involved before stem cell transplantation for amyloidosis is the most important factor in predicting subsequent survival. Stem cell transplantation should be considered as a treatment option for selected patients with amyloidosis.

Abstract
PURPOSE Although high-dose chemotherapy supported by autologous peripheral-blood progenitor-cell (PBPC) transplantation improves response rates and survival for patients with multiple myeloma, all patients eventually develop progressive disease after transplantation. It has been hypothesized that depletion of malignant plasma cells from autografts may improve outcome by reducing infused cells contributing to relapse. PATIENTS AND METHODS A randomized phase III study using the CEPRATE SC System (Cellpro, Bothell, WA) to enrich CD34(+) autograft cells and passively purge malignant plasma cells was completed in 190 myeloma patients randomized to receive an autograft of CD34-selected or unselected PBPCs. RESULTS After CD34 selection, tumor burden was reduced by 1.6 to 6.0 logs (median, 3.1), with 54% of CD34-enriched products having no detectable tumor. Median time to count recovery, number of transfusions, transplantation-related mortality, and days in hospital were equivalent between the two transplantation arms. With a median follow-up of 37 months, 33 patients (36%) in the selected and 34 patients (35%) in the unselected arm had died (P =.784). Median overall survival in the selected arm was reached at 50 months and is not reached at this time in the unselected arm (P =.78). Median disease-free survival was 100 versus 104 weeks (P =.82), with 67% of patients in the selected arm and 66% of patients in the unselected arm relapsing. CONCLUSION This phase III trial demonstrates that although CD34 selection significantly reduces myeloma cell contamination in PBPC collections, no improvement in disease-free or overall survival was achieved.

Abstract
Forty-one patients with multiple myeloma were treated with a novel stem cell mobilisation regimen. The primary end points were adequate stem cell mobilising ability (>1% circulating CD34-positive cells) and collection (> or = 4 x 10(6) CD34-positive cells/kg), and safety. The secondary end point was activity against myeloma. The regimen (d-TEC) consisted of dexamethasone, paclitaxel 200 mg/m(2) i.v., etoposide 60 mg/kg i.v., cyclophosphamide 3 g/m(2) i.v., and G-CSF 5-10 microg/kg/day i.v. A total of 84 cycles were administered to these 41 individuals. Patient characteristics included a median age of 53 years, a median of five prior chemotherapy cycles, and a median interval of 10 months from diagnosis of myeloma to first cycle of d-TEC. Seventy-five percent of the patients had stage II or III disease, 50% had received carmustine and/or melphalan previously, and 25% had received prior radiation therapy. Eighty-eight percent of patients mobilised adequately after the first cycle of d-TEC and 91% mobilized adequately after the second cycle. An adequate number of stem cells were collected in 32 patients. Of the remaining nine patients, three mobilised, but stem cells were not collected, two mobilised but stem cell collection was < 4 x 10(6) CD34-positive cells/kg, three did not mobilise, and one died of disease progression. Major toxicities included pancytopenia, alopecia, fever and stomatitis. One patient died from multi-organ failure and progressive disease. Fifty percent of evaluable patients demonstrated a partial response and 28.6% of patients had a minor response. This novel dose-intense regimen was safe, capable of stem cell mobilisation and collection, even in heavily pre-treated patients, and active against the underlying myeloma.

Abstract
Eight multiple myeloma patients participated in a phase I trial evaluating the feasibility and safety of subcutaneous vaccination with adenovirus engineered, autologous plasma cells after high-dose therapy. Plasma cells were concentrated from bone marrow harvests by negative selection and high gradient magnetic separation. The mean plasma cell yield was 2.61 x 10(8). Transgene expression measured 48 h after plasma cell infection with an IL-2 expressing adenovirus averaged 2.95 ng/ml/10(6) cells. Vaccine production was successful for 88% of patients. Two months after high-dose therapy, six patients received from one to five injections of 3.5-9.0 x 10(7) cells/vaccine. Vaccines were well tolerated with only minor systemic symptoms reported. Injection with tumor cells induced a local inflammatory response consisting predominantly of CD8+ and/or TIA-1+ T-lymphocytes. Myeloma specific anti-tumor responses, assessed by interferon-gamma (IFN-gamma) release and cytotoxic T cell killing of autologous tumor cells, were not enhanced after vaccination in one evaluable patient. Clinical response, manifested as a decrease in serum paraprotein, was not observed in the one patient who had measurable disease at the time of vaccination. These results demonstrate that the generation of adenovector modified plasma cell vaccines is technically feasible and can be safely administered post-transplant. Further studies of immunlogic and clinical efficacy are required.

Abstract
High-dose therapy followed by autologous stem cell transplantation (ASCT) prolongs survival in patients with multiple myeloma and is relatively safe with treatment-related mortality rates of only 1-5%. Interstitial pneumonitis (IP) is normally an infrequent complication of ASCT with a reported incidence of 0-16%. Between 1992 and 1998, 94 myeloma patients at our center underwent ASCT using a high-dose regimen of etoposide (60 mg/kg), melphalan (160 mg/m2) and fractionated TBI 12 Gy. An unusually high incidence of IP (29/94 (31%)) was noted. Mortality in the IP patients was high at 45%. Patients developing IP were more frequently anemic than those who did not have pulmonary complications (hemoglobin <100 g/l) prior to transplant (P = 0.03) but no other pre-transplant factors were predictive (ie age, gender, smoking history, CMV status, pulmonary function, creatinine, beta2-microglobulin or C-reactive protein, prior cumulative chemotherapy or chest irradiation). A significantly lower IP rate was noted in 32 contemporaneous myeloma control patients conditioned with BU-CY without TBI at our center (3/32 (9%); P=0.03) and in 32 lymphoma control patients conditioned with the same melphalan and etoposide regimen minus the TBI (2/32 (6%); P = 0.003). In contrast, when using the same TBI-containing regimen in 32 concurrently treated lymphoma patients, an increase in IP similar to that seen in our myeloma cohort (7/32 (22%); P = 0.3) was noted. This strongly suggests that TBI is the predominant factor contributing to lung toxicity. We conclude that radiation-associated pneumonitis cannot be easily predicted by pretransplant variables. Therefore surveillance, early recognition and prompt therapy are recommended.
