Clin Oncol (R Coll Radiol) 2023:S0936-6555(23)00218-2. [PMID: 37344243 DOI: 10.1016/j.clon.2023.06.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Revised: 05/31/2023] [Accepted: 06/06/2023] [Indexed: 06/23/2023]
Abstract
Adjuvant radiotherapy is an integral component in the management of soft-tissue sarcomas. Brachytherapy is a very convenient and conformal way of delivering adjuvant radiotherapy in such tumours, which spares the surrounding normal tissue. Randomised studies have established the efficacy of brachytherapy in the adjuvant setting, with a 5-year local control of 80-85%. High dose rate, low dose rate and pulsed dose rate have shown equivalent local control, but high dose rate has gained popularity owing to patient convenience, radiation safety and flexibility in dose optimisation. Freehand insertion perioperative brachytherapy (intraoperative placement and postoperative treatment) is the most commonly used technique in soft-tissue sarcomas, with intraoperative radiotherapy and radioactive seed placement being the less commonly used techniques. Brachytherapy can be used as monotherapy or in combination with external beam radiotherapy, such as in cases of close/positive margins for safe dose escalation. Although the quantum of side-effects with external beam radiotherapy has considerably reduced with the evolution of technology and the introduction of intensity modulation (intensity-modulated radiotherapy), brachytherapy still scores better in terms of dose conformality, especially in recurrent tumours (previously irradiated) and when used to treat paediatric and geriatric patients.

Abstract
BACKGROUND Brachytherapy (BT) delivers highly conformal radiation and spares surrounding tissues, which may limit late effects in pediatric, adolescent, and young adult (AYA) patients. We aimed to characterize trends in BT use for this population in the United States, focusing on patients with rhabdomyosarcoma (RMS). METHODS The National Cancer Database was queried to identify patients ≤ 21 who were treated for solid tumor malignancies in the United States from 2004 to 2016. We obtained disease, treatment, and outcome data for patients treated with BT, in particular for RMS. RESULTS 99 506 pediatric and AYA patients met study inclusion. Of these, 22 586 (23%) received radiation therapy (external beam radiation therapy [EBRT] and/or BT) and 240 (0.2%) received BT. Among patients treated with BT, 139 (58%) underwent surgery and 58 (24%) received EBRT. A total of 3836 patients were treated for RMS during this period. Of these, 2531 (66%) received any radiation and 37 (1%) received BT (EBRT + BT in 3, BT in 34). Of patients treated with BT for RMS, 28 (76%) underwent surgery + BT. Survival data were available for 31 patients treated with BT for RMS. With a median follow-up of 63 months, overall survival was 100% for patients with RMS of a favorable site treated with BT. CONCLUSIONS BT is rarely used to treat pediatric and AYA patients in the United States. Patients treated with BT for RMS experienced favorable survival, suggesting that this approach may not compromise oncologic outcomes and warrants further study as a therapeutic option in pediatric and AYA patients, specifically in RMS.

Abstract
PURPOSE Growing data supports the role of radiation therapy in the treatment of soft tissue sarcoma (STS). Brachytherapy has been used for decades in the management of STS and can be utilized as monotherapy or as a boost to external beam radiation. We present updated guidelines from the American Brachytherapy Society regarding the utilization of brachytherapy in the management of STS. METHODS AND MATERIALS Members of the American Brachytherapy Society with expertise in STS and STS brachytherapy created an updated clinical practice guideline including step-by-step details for performing STS brachytherapy based on a literature review and clinical experience. RESULTS Brachytherapy monotherapy should be considered for lower-recurrence risk patients or after a local recurrence following previous external beam radiation; a brachytherapy boost can be considered in higher-risk patents meeting implant criteria. Multiple dose/fractionation regimens are available, with determination based on tumor location and treatment intent. Techniques to limit wound complications are based on the type of wound closure; wound complication can be mitigated with a delay in the start of brachytherapy with immediate wound closure or by utilizing a staged reconstruction technique, which allows an earlier treatment start with a delayed wound closure. CONCLUSIONS These updated guidelines provide clinicians with data on indications for STS brachytherapy as well as guidelines on how to perform and deliver high quality STS brachytherapy safely with minimal toxicity.

Abstract
Sarcomas are a rare heterogeneous group of malignant neoplasms that can arise in almost any anatomic site and any age. Close collaboration among adult and pediatric cancer specialists in the management of these tumors is of foremost importance. In this review, we present the current multidisciplinary organization in care of patients with sarcoma in France and we review the main advances made in the last decades in systemic and radiotherapy treatment in the main sarcoma types diagnosed in children, adolescents and young adults (AYA), thanks to the international collaboration.

Abstract
BACKGROUND AND PURPOSE Survival after relapse of head and neck rhabdomyosarcoma (HNRMS) after prior external beam radiotherapy (EBRT) is poor, since options for adequate local treatment are often lacking. In this study we describe our experience with salvage AMORE in patients with relapsed HNRMS after prior EBRT. MATERIALS AND METHODS Patients with relapsed HNRMS after prior EBRT in which salvage AMORE treatment was considered feasible were analysed; this includes patients with parameningeal, head and neck non-parameningeal and orbital localization. AMORE treatment consisted of Ablative surgery, MOuld technique brachytherapy and surgical REconstruction. RESULTS In total 18 patients received salvage AMORE treatment; nine patients had relapsed parameningeal (PM) RMS, two patients had relapsed head and neck non-parameningeal RMS (HN-nonPM) and seven patients had relapsed orbital RMS. Local control rate was 67% and 5-year overall survival was 54% (95% confidence interval: 31-78%); 3/9 patients with PM RMS, 0/2 patients with HN-nonPM RMS and 6/7 patients with orbital RMS were alive after a median follow-up of 8.6 years. One patient with PM RMS survived more than 5 years after which he died from a secondary cancer. Six patients developed a local relapse (of which one patient also developed a distant metastasis) and two patients developed distant metastases. CONCLUSIONS Salvage AMORE treatment is a feasible and effective local therapy approach even after prior EBRT. Since salvage AMORE treatment is sometimes the only curative option in patient with relapsed HNRMS, we encourage physicians to consider salvage AMORE treatment for patients with relapsed HNRMS after prior EBRT.

Abstract
Head and neck rhabdomyosarcoma (HNRMS) is a uniquely challenging site to treat given the young patient age and critical anatomy of the head and neck region. We review the characteristics, management, and future directions in the treatment of HNRMS. Most patients who present with HNRMS have unresectable disease due to functional and/or cosmetic constraints. However, surgical resection and brachytherapy serve a critical role in select patients. The treatment paradigm for the majority of patients with HNRMS consists of definitive chemotherapy and radiation therapy. As the incidence of late toxicities increases with improved survival, modern efforts must focus on ways to decrease long-term morbidity. We recommend a multimodal approach emphasizing the preservation of form and function for the treatment of HNRMS.

Abstract
PURPOSE Survival in patients with orbital rhabdomyosarcoma (RMS) is excellent. Therefore, new local treatment modalities, such as brachytherapy, have been developed to minimize adverse events. Since 1990, patients with orbital RMS and a residual tumor after induction chemotherapy were eligible for resection and brachytherapy. Otherwise patients received external beam radiotherapy. In this study, the authors describe the outcome for 20 patients with primary orbital RMS. The aim was to assess risk factors for treatment failure in this single center cohort. METHODS In this retrospective cohort study, the authors reviewed imaging studies, surgery reports, histology reports, and radiotherapy plans in a multidisciplinary setting. The authors included 20 consecutive patients with orbital RMS, treated between 1990 and 2007, (median age: 7.4 years, range: 0.7-16.1; median follow up: 11.5 years). RESULTS After induction chemotherapy, 12 patients were treated with surgery and brachytherapy, 2 with external beam radiotherapy, and in 5 patients who achieved complete remission, local treatment was withheld. In 1 patient, brachytherapy was incorrectly withheld after delayed surgery. Seven patients relapsed (no local treatment, N = 2; surgery and brachytherapy, N = 2; external beam radiotherapy, N = 2; surgery only, N = 1). The authors found no patient, tumor, or treatment characteristics that predisposed for treatment failure. Ten-year-overall survival and event-free survival were 89% and 65%, respectively. CONCLUSIONS Overall survival in this cohort of orbital RMS patients was good, including surgery and brachytherapy as treatment modality for orbital RMS resulted in an effective local treatment approach with fewer adverse events than external beam radiotherapy. The authors could not identify factors predisposing for treatment failure.

Abstract
OBJECTIVES To determine the hearing status of survivors treated for head and neck rhabdomyosarcoma (HNRMS) at long-term follow-up. DESIGN Cross-sectional long-term follow-up study. SETTING Tertiary comprehensive cancer centre. PARTICIPANTS Survivors treated for HNRMS during childhood in two concurrent cohorts; survivors in London had been treated with external beam radiotherapy (EBRT-based local therapy); survivors in Amsterdam were treated with AMORE (Ablative surgery, MOuld technique afterloading brachytherapy and surgical REconstruction) if feasible, otherwise EBRT (AMORE-based local therapy). MAIN OUTCOME MEASURES We assessed hearing status of HNRMS survivors at long-term follow-up. Hearing thresholds were obtained by pure-tone audiometry. METHODS We assessed the hearing thresholds, the number of patients with clinically relevant hearing loss and hearing impairment graded according to the Common Terminology Criteria for Adverse Events version 4.0 (CTCAEv4) and Boston criteria. Furthermore, we compared hearing loss between survivors treated with EBRT-based local therapy (London) and AMORE-based local therapy (Amsterdam). RESULTS Seventy-three survivors were included (median follow-up 11 years). We found clinically relevant hearing loss at speech frequencies in 19% of survivors. Multivariable analysis showed that survivors treated with EBRT-based treatment and those with parameningeal tumours had significantly more hearing impairment, compared to survivors treated with AMORE-based treatment and non-parameningeal tumours. CONCLUSIONS One in five survivors of HNRMS developed clinically relevant hearing loss. AMORE-based treatment resulted in less hearing loss compared to EBRT-based treatment. As hearing loss was highly prevalent and also occurred in survivors with orbital primaries, we recommend systematic audiological follow-up in all HNRMS survivors.

Abstract
BACKGROUND To evaluate a strategy whereby extensive surgery ± external radiotherapy (RT) could improve local control in pterygopalatine/infratemporal fossa (PIF) sarcoma. PROCEDURE Forty-one patients with a diagnosis of sarcoma involving the PIF and referred to our Institute from 1984 to 2009 were included in the analysis. Patients received multidrug chemotherapy and radiotherapy ± surgery, depending on the period of treatment. RESULTS The median age at diagnosis was 7.6 years (range: 0.1-22 years). There were 36 RMS, 3 undifferentiated sarcoma and 2 other soft-tissue sarcomas. Sixty-eight percent of patients had meningeal risk factors at diagnosis. Local treatment consisted of RT alone in 19 patients, surgery in combination to RT in 19 patients and surgery alone in 3 patients. The local progression rate (LPR) at 5 years was 45% for the entire population, 59% for the 19 patients treated with RT alone and 34% for the 22 patients who had surgery as part of their treatment. All locoregional failures after extensive surgery occurred at the skull base and/or in leptomeningeal spaces. CONCLUSIONS Multidisciplinary approach including extensive surgery for PIF sarcoma is feasible and yields good local control with 15/22 patients in local complete remission. Future studies are warranted to confirm these promising results, to evaluate the possibility of avoiding RT or limiting the RT field, and to extend the indication for extensive surgery to other "worse" sites of PM sarcoma such as the paranasal sinuses.

Abstract
INTRODUCTION Rhabdomyosarcomas in the orbit form a major challenge in terms of cure without severe side effects in childhood cancer. Our specifically developed approach consists of applying brachytherapy to the tumor area using a mold. Analysis of its results for 20 patients was performed. METHODS AND MATERIALS Thirteen patients were referred for brachytherapy if complete remission was not reached after chemotherapy (Group I) and 7 in case of relapse (Group II). In total, 20 patients were treated between 1991 and 2007. Four were female and 16 male; their ages varied from 1.1 to 16.5 years, with an average of 8.5 years. After macroscopically radical tumor resection, molds with holes drilled to hold flexible catheters were placed into the orbit. The dose to the clinical target volume was 40-50 Gy. RESULTS Three patients of Group I and 1 patient of Group II developed local recurrence and underwent exenteration. The progression-free survival in Group I is 71.9% (95% CI 0.44-1.0), in Group II 85.7% (95% CI 0.60-1.0), the overall 5-year survival rate of the entire group is 92% (95% CI 0.76-1.0). During treatment, no serious side effects were observed. The late complications encountered in this series were cataract in 2 patients, 1 of whom also developed mild retinopathy. Two patients with ptosis needed surgical correction. No facial asymmetries or bone growth anomalies were observed. CONCLUSIONS This entire procedure of brachytherapy with a mold offers a tailor-made treatment for orbital rhabdomyosarcomas with only few signs of late toxicity.

The AMORE protocol for advanced-stage and recurrent nonorbital rhabdomyosarcoma in the head-and-neck region of children: a radiation oncology view. Int J Radiat Oncol Biol Phys 2009; 74:1555-62. [PMID: 19250759 DOI: 10.1016/j.ijrobp.2008.10.029] [Citation(s) in RCA: 36] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2008] [Revised: 10/07/2008] [Accepted: 10/08/2008] [Indexed: 11/21/2022]
Abstract
PURPOSE A multidisciplinary approach, consisting of consecutive Ablative Surgery, MOld technique with afterloading brachytherapy and immediate surgical REconstruction (AMORE) applied after chemotherapy, was designed for children with rhabdomyosarcoma in the head-and-neck region. Analysis of the first 42 patients was performed. METHODS AND MATERIALS After macroscopically radical tumor resection, molds were constructed for each individual to fit into the surgical defect. The molds, made of 5-mm-thick layers of thermoplastic rubber, consisted of different parts. Flexible catheters were positioned between layers. After brachytherapy, the molds were removed. Surgical reconstruction was performed during the same procedure. RESULTS Dose to the clinical target volume varied from 40 to 50 Gy for the primary treatment (31 patients) and salvage treatment groups (11 patients). There were 18 females and 24 males treated from 1993 until 2007. Twenty-nine tumors were located in the parameningeal region, and 13 were located in the nonparameningeal region. Patient age at the time of AMORE was 1.2-16.9 years (average, 6.5 years). Follow-up was 0.2-14.5 years (average, >5.5 years). Eleven patients died, 3 with local recurrence only, 6 with local and distant disease, 1 died of distant metastases only, and 1 patient died of a second primary tumor. Overall 5-year survival rates were 70% for the primary treatment group and 82% for the salvage group. Treatment was well tolerated, and acute and late toxicity were mild. CONCLUSIONS The AMORE protocol yields good local control and overall survival rates, and side effects are acceptable.

Abstract
Paediatric soft tissue sarcomas (STS) are a group of malignant tumours that originate from primitive mesenchymal tissue and account for 7% of all childhood tumours. Rhabdomyosarcomas (RMS) and undifferentiated sarcomas account for approximately 50% of soft tissue sarcomas in children and non-rhabdomyomatous soft tissue sarcomas (NRSTS) the remainder. The prognosis and biology of STS tumours vary greatly depending on the age of the patient, the primary site, tumour size, tumour invasiveness, histologic grade, depth of invasion, and extent of disease at diagnosis. Over recent years, there has been a marked improvement in survival rates in children and adolescents with soft tissue sarcoma and ongoing international studies continue to aim to improve these survival rates whilst attempting to reduce the morbidity associated with treatment. Radiology plays a crucial role in the initial diagnosis and staging of STS, in the long term follow-up and in the assessment of many treatment related complications. We review the epidemiology, histology, clinical presentation, staging and prognosis of soft tissue sarcomas and discuss the role of radiology in their management.

Abstract
Brachytherapy is a sophisticated radiation method in which radioisotopes are placed inside or at a short distance from the tumour. The volume of tissue that receives the prescribed dose of radiotherapy is therefore fairly small compared with that used in standard radiotherapy techniques. In paediatric oncology, this method of radiation delivery can have a favourable effect on several undesirable long-term side-effects that sometimes develop in children who receive radiotherapy, such as growth retardation and development of second primary tumours. Here, we describe the rationale for use of brachytherapy in children with cancer, the methods of the different brachytherapy techniques available, and the results obtained with several brachytherapy regimens in expert institutions throughout the world.
