Brachytherapy for rhabdomyosarcoma: Survey of international clinical practice and development of guidelines.

BACKGROUND AND PURPOSE: The purpose of this study was to address the lack of published data on the use of brachytherapy in pediatric rhabdomyosarcoma by describing current practice as starting point to develop consensus guidelines. MATERIALS AND METHODS: An international expert panel on the treatment of pediatric rhabdomyosarcoma comprising 24 (pediatric) radiation oncologists, brachytherapists and pediatric surgeons met for a Brachytherapy Workshop hosted by the European paediatric Soft tissue Sarcoma Study Group (EpSSG). The panel's clinical experience, the results of a previously distributed questionnaire, and a review of the literature were presented. RESULTS: The survey indicated the most common use of brachytherapy to be in combination with tumor resection, followed by brachytherapy as sole local therapy modality. HDR was increasingly deployed in pediatric practice, especially for genitourinary sites. Brachytherapy planning was mostly by 3D imaging based on CT. Recommendations for patient selection, treatment requirements, implant technique, delineation, dose prescription, dose reporting and clinical management were defined. CONCLUSIONS: Consensus guidelines for the use of brachytherapy in pediatric rhabdomyosarcoma have been developed through multicenter collaboration establishing the basis for future work. These have been adopted for the open EpSSG overarching study for children and adults with Frontline and Relapsed RhabdoMyoSarcoma (FaR-RMS).

Correlation between peritoneal cancer index and survival in advanced epithelial ovarian cancer with complete resection.

OBJECTIVE: The aim of this study was to investigate the relation between the peritoneal cancer index, overall survival, and recurrence free survival, in patients with epithelial ovarian cancer. METHODS: Patients treated at the Gustave-Roussy Institute between December 2004 and November 2017 for advanced epithelial ovarian cancer in complete resection were included. The correlation between the peritoneal cancer index and survival was studied using statistical modeling. Multivariate analysis was performed with a logistic regression model. RESULTS: Of the 351 patients included, 94 (27%) had initial surgery and 257 (73%) had interval surgery. Median follow-up was 52.7 months (range 47.6-63.9). Median peritoneal cancer index was 10 (range 0-32). The linear model best represented the relationship between peritoneal cancer index and overall survival. Patients with neoadjuvant chemotherapy had a greater instantaneous risk of baseline death than those with initial surgery, as well as a more rapid increase in this risk as the peritoneal cancer index increased. Overall survival and recurrence free survival were better in the initial surgery group (103.4 months (79.1-not reached (NR)) vs 66.5 months (59.1-95.3) and 31.8 months (23.7-48.7) vs 25.9 months (23.2-29), respectively). Risk factors for death were body mass index, peritoneal cancer index, and need for neoadjuvant chemotherapy. CONCLUSION: The peritoneal cancer index is a prognostic indicator, but its linear relationship with survival precluded setting a unique peritoneal cancer index cut-off. Moreover, the prognostic impact of peritoneal cancer index was stronger in the setting of neoadjuvant chemotherapy.

Vulvar Carcinoma: Standard of Care and Perspectives.

PURPOSE: Treatment of vulvar carcinoma (VC) is challenging. The objectives of this review were to describe for clinicians the epidemiologic and clinical aspects of VC, the standard of care in terms of primary local treatment and systemic therapies, and the recent innovations and perspectives emerging from translational research in immuno-oncology. DESIGN: We conducted a comprehensive review outlying the clinical aspects and biologic background of vulvar cancer, highlighting modern treatment strategies on the basis of a personalized approach. RESULTS: Epidemiologic data showed a recent rise in incidence of VC, attributed to human papillomavirus. Surgery is the mainstay of primary treatment, but multimodal approaches are frequently required in the presence of adverse prognosis histopathologic factors. Chemoradiation is indicated when organ-sparing surgery is not feasible. However, inability to achieve high locoregional control rates in advanced cases and the morbidity associated with local treatments are still key issues. Recent clinical data showed the benefit of individualized strategies combining organ-sparing surgical strategies, less invasive lymph node staging procedures, and refinement in radiotherapy modalities. Among the most important research area, there is a sound rationale for testing modern systemic approaches such as immune checkpoint inhibitors in selected patients with recurrent and/or metastatic tumors. Although no specific data exist for VC, the role of supportive care and post-treatment rehabilitation strategies is also crucial. CONCLUSION: There are still insufficient studies dedicated to patients with VC. Public health programs for prevention, screening, and early diagnosis are required, and clinical research should be strengthened to provide high-quality clinical evidence and improve patients' oncologic and functional outcomes.

Integration of the Molecular Classification of Endometrial Carcinoma to Select Patients for Fertility Sparing Strategies.

Fertility-sparing treatment (FST) for endometrial carcinoma (EC) is an option for a subgroup of young women with low-risk disease. The low-risk group comprises patients with endometrioid EC stage IA, grade 1, with or without focal lymphovascular invasion. In the era of molecular subtyping, treatment de-escalation for some EC subtypes is recommended. Recommendations for fertility-preserving treatments were developed regardless of the molecular classification of EC. However, few studies have focused on this topic. In this review, we summarize the actual data available in the literature and discuss the impact of some molecular subtypes of FST.

Redefining the role of pulsed-dose-rate brachytherapy in cervical cancer treatment using a preplanned approach.

INTRODUCTION: This study aims to determine predictive factors for cervical cancer patients who would benefit more from high-dose-rate (HDR) or pulsed-dose-rate (PDR) brachytherapy. METHODS: The sample included 50 patients treated with brachytherapy following external radiochemotherapy. PDR plans were compared to HDR preplans, with a focus on patients who may benefit from PDR using preplan metrics and clinical variables. The expected clinical effect was quantified using a tumor control probability model. RESULTS: Results showed PDR plans with 60 pulses to be optimal for achieving target clinical goals for D90CTVHR. A CTVHR volume of >67.5cc and/or D90CTVHR dose on the HDR preplan of <31.1 Gy was the strongest indicator for patient selection who would gain >3% increase in TCP with PDR. The process showed 96% accuracy, 88% sensitivity, and 98% specificity. Only 16% of patients showed a relevant benefit from PDR over HDR, with a mean D90CTVHR of 7 Gy higher and a mean TCP at 3 years of 4.8% higher for PDR. The benefit of PDR is highly influenced by the choice of alpha/beta ratio and repair halftime. CONCLUSION: A small subset of cervical cancer patients may gain from PDR over HDR. CTVHR volume and preplan D90CTVHR doses may be useful in selecting patients for PDR brachytherapy.

The organization of care in pediatric radiotherapy across SIOP Europe affiliated centers: A multicenter survey in the framework of the 'Joint Action on Rare Cancers' project.

BACKGROUND/PURPOSE: To reduce inequalities among SIOPE-affiliated countries, standard and optional levels to deliver 'Good Clinical Practice' compliant treatment in pediatric radiation oncology have been published. The aim of this project was to map the availability of pediatric radiotherapy resources across SIOPE-affiliated radiotherapy departments. MATERIALS/METHODS: An online survey with 34 questions was distributed to 246 radiotherapy departments across 35 SIOPE-affiliated countries. In addition to demographic data, 15 general items related to the organization of the radiotherapy process, and 10 radiotherapy-specific items were defined. For each of the 25 items, sum scores were calculated per center and country. Mann-Whitney U tests were used to analyze associations. RESULTS: Between March-June 2019, 121 departments (49 %) out of 31 countries (89 %) completed the survey. At center level, involvement of core disciplines in tumor boards (28 %), and integration of dedicated pediatric radiation therapy technologists (24 %) are limited, while rare & complex brachytherapy procedures are performed in many centers (23 %). For general and radiotherapy-specific items respectively, a relevant variation of sum scores was observed across countries (Δgeneral: ≤10 points; ΔRT_specific: ≤5 points) and among centers within a country (Δgeneral: ≤9 points; ΔRT_specific: ≤6 points). Sum scores for general and radiotherapy-specific items were higher in countries with a high-income (p < 0.01) and higher health development index (p < 0.01). A larger annual number of irradiated pediatric patients was associated with higher sum scores for general items (p < 0.01). CONCLUSION: This survey demonstrates the disparities in organization of pediatric radiotherapy departments between SIOPE-affiliated countries and centers within the same country. Investment is needed to reduce inequalities in pediatric radiotherapy care.

Stages I-III Inoperable Endometrial Carcinoma: A Retrospective Analysis by the Gynaecological Cancer GEC-ESTRO Working Group of Patients Treated with External Beam Irradiation and 3D-Image Guided Brachytherapy.

BACKGROUND/PURPOSE: Analyse the outcomes of stages I-III inoperable endometrial cancer (IEC) patients treated with external-beam-irradiation (EBRT) and 3D-image-guided-brachytherapy (IGBT). MATERIAL AND METHODS: Medical records of IEC patients receiving EBRT + IGBT in eight European and one Canadian centres (2004-2019) were examined, including: pelvic ± para-aortic EBRT and lymph node boost; anaesthetic procedure, applicators, BT-planning imaging, clinical target volume (CTV), brachytherapy schedule, and EQD2 to the CTV(α/ß=4.5Gy) and D2 cm3(α/ß=3Gy) for organs at risk. Complications are evaluated using CTCAEv4 scores. The 2- and 5-year survival probability according to stages was estimated (cancer-specific survival (CSS), disease-free survival (DFS), local relapse-free survival (LRFS), loco-regional relapse-free survival (LRRFS), and distant metastasis-free survival (DMFS)). STATISTICS: descriptive analysis and the Kaplan-Meier method. RESULTS: 103 patients (stages: I-44, II-14, III-44) were included. Median follow-up: 28 months (7-170). All patients received pelvic ± para-aortic EBRT. Median D90-EQD2(α/ß=4.5) to the CTV:73.3 Gy (44.6-132.7), 69.9 Gy (44.7-87.9 and 75.2 Gy (55.1-97) in stages I, II, and III, respectively. Thirty patients presented relapse (stages: 10-I, 3-II, 17-III): 24 uterine (stages: 7-I, 3-II, 14-III), 15 nodal (stages: 4-I, 1-II, 10-III), and 23 distant (stages: 6-I, 2-II, 15-III). Five year CSS was 71.2% (stages: 82%-I-II and 56%-III) and DFS, LRFS, LRRFS, and DMFS were 55.5%, 59%, 72%, and 67.2%, respectively. Late G3-G4 complications (crude): 1.3% small bowel, 2.5% rectum, and 5% bladder. CONCLUSION: In stages I-III of the IEC, EBRT + IGBT offer good 2- and 5-year CSS of 88.7% and 71.2%, respectively, with the best outcomes in stages I-II. Prospective studies are needed to determine how better outcomes can be achieved.

Outcome and late effects of patients treated for childhood vaginal malignant germ cell tumors.

PURPOSE: Vaginal malignant germ cell tumors (MGCT) are rare, occurring in children less than 2 years old and raise the question of the optimal local treatment. METHODS: We included children treated for vaginal MGCT according to the French TGM-95/2013 regimen. Patients were classified as standard risk (SR: localized disease and alpha-fetoprotein (AFP) < 10,000 ng/mL) or high risk (HiR: metastatic and/or AFP > 10,000 ng/mL) and were treated, respectively, with three to five VBP (vinblastine-bleomycin-cisplatin) or four to six VIP (etoposide-ifosfamide-cisplatin), followed by conservative surgery and/or brachytherapy in case of post-chemotherapy residuum. RESULTS: Fourteen patients were included (median age = 12 months), of which six (43%) were classified as HiR. AFP levels were normalized after first-line chemotherapy in all cases but one. A vaginal post-chemotherapy residuum (median size = 8 mm, range: 1-24 mm) was observed in 13/14 patients, treated by complete resection in seven of 13 (viable cells in three of seven), incomplete resection in four of 13 (viable cells in two of four), with adjuvant brachytherapy in two of 13, and exclusive brachytherapy in two of 13 (viable cells in one of six). Among the six patients with viable disease, four patients received adjuvant chemotherapy. One patient (SR) experienced immediate postoperative relapse despite presenting no viable residual cells and was treated with four VIP cycles and brachytherapy. At last follow-up (median = 4.6 years, range: 0.5-16), all patients were alive in complete remission. Five patients suffered from vaginal sequelae with synechiae and/or stenosis (of whom four had undergone brachytherapy). CONCLUSION: Childhood vaginal MGCTs show a highly favorable prognosis with risk-adapted chemotherapy and local treatment of post-chemotherapy residuum (preferably by conservative surgery with partial vaginectomy). Brachytherapy could be an alternative when conservative surgery is not deemed possible or in cases of incomplete resection with residual viable cells.

Hallmarks of the Tumour Microenvironment of Gliomas and Its Interaction with Emerging Immunotherapy Modalities.

Gliomas are aggressive, primary central nervous system tumours arising from glial cells. Glioblastomas are the most malignant. They are known for their poor prognosis or median overall survival. The current standard of care is overwhelmed by the heterogeneous, immunosuppressive tumour microenvironment promoting immune evasion and tumour proliferation. The advent of immunotherapy with its various modalities-immune checkpoint inhibitors, cancer vaccines, oncolytic viruses and chimeric antigen receptor T cells and NK cells-has shown promise. Clinical trials incorporating combination immunotherapies have overcome the microenvironment resistance and yielded promising survival and prognostic benefits. Rolling these new therapies out in the real-world scenario in a low-cost, high-throughput manner is the unmet need of the hour. These will have practice-changing implications to the glioma treatment landscape. Here, we review the immunobiological hallmarks of the TME of gliomas, how the TME evades immunotherapies and the work that is being conducted to overcome this interplay.

Prognostic Factors in Patients with Metastatic Spinal Cord Compression Secondary to Lung Cancer-A Retrospective UK Single-Centre Study.

PURPOSE: Metastatic spinal cord compression (MSCC) is a severe complication of cancer that can lead to irreversible neurological impairment, necessitating prompt recognition and intervention. This retrospective, single-centre study aimed to determine the prognostic factors and survival rates among patients presenting with MSCC secondary to lung cancer. METHODS AND MATERIALS: We identified 74 patients with epidural metastases-related spinal cord compression and a history of lung cancer through the electronic database of Medway Maritime Hospital in the United Kingdom (UK), spanning the period from April 2016 to September 2021. Among them, 39 were below 55 years old, while 35 were aged 55 years or older; 24 patients were diagnosed with small cell lung cancer (SCLC), and 50 patients had non-small cell lung cancer (NSCLC). RESULTS: The median overall survival (OS) was 5.5 months, with 52 out of 74 patients dying within 6 months of diagnosis with MSCC. For the entire cohort, the statistically significant variables on multi-variate analysis were cancer type (NSCLC had improved OS), the number of involved vertebrae (one to two vertebrae involvement had improved OS), and the time taken to develop motor deficits (≤10 days to develop motor deficits had worsened OS). For the NSCLC cohort, the statistically significant variables on multivariate analysis were molecular alterations (patients with epidermal growth factor receptor (EGFR) mutation), pre-treatment ambulatory status, Eastern Cooperative Oncology Group (ECOG) performance status, and the time taken to develop motor deficits. CONCLUSIONS: Within the entire cohort, patients diagnosed with NSCLC and spinal metastases affecting one to two vertebrae exhibited enhanced OS. Within the NSCLC subgroup, those with EGFR mutations who were ambulatory and possessed an ECOG performance status of 1-2 demonstrated improved OS. In both the entire cohort and the NSCLC subgroup, the development of motor deficits within a period of ≤10 days was associated with poor OS.

A common [18F]-FDG PET radiomic signature to predict survival in patients with HPV-induced cancers.

Locally advanced cervical cancer (LACC) and anal and oropharyngeal squamous cell carcinoma (ASCC and OPSCC) are mostly caused by oncogenic human papillomaviruses (HPV). In this paper, we developed machine learning (ML) models based on clinical, biological, and radiomic features extracted from pre-treatment fluorine-18-fluorodeoxyglucose positron emission tomography ([18F]-FDG PET) images to predict the survival of patients with HPV-induced cancers. For this purpose, cohorts from five institutions were used: two cohorts of patients treated for LACC including 104 patients from Gustave Roussy Campus Cancer (Center 1) and 90 patients from Leeds Teaching Hospitals NHS Trust (Center 2), two datasets of patients treated for ASCC composed of 66 patients from Institut du Cancer de Montpellier (Center 3) and 67 patients from Oslo University Hospital (Center 4), and one dataset of 45 OPSCC patients from the University Hospital of Zurich (Center 5). Radiomic features were extracted from baseline [18F]-FDG PET images. The ComBat technique was applied to mitigate intra-scanner variability. A modified consensus nested cross-validation for feature selection and hyperparameter tuning was applied on four ML models to predict progression-free survival (PFS) and overall survival (OS) using harmonized imaging features and/or clinical and biological variables as inputs. Each model was trained and optimized on Center 1 and Center 3 cohorts and tested on Center 2, Center 4, and Center 5 cohorts. The radiomic-based CoxNet model achieved C-index values of 0.75 and 0.78 for PFS and 0.76, 0.74, and 0.75 for OS on the test sets. Radiomic feature-based models had superior performance compared to the bioclinical ones, and combining radiomic and bioclinical variables did not improve the performances. Metabolic tumor volume (MTV)-based models obtained lower C-index values for a majority of the tested configurations but quite equivalent performance in terms of time-dependent AUCs (td-AUC). The results demonstrate the possibility of identifying common PET-based image signatures for predicting the response of patients with induced HPV pathology, validated on multi-center multiconstructor data.

Recommandations pour la pratique clinique Nice/Saint-Paul-de-Vence 2022­2023 : prise en charge du cancer de l'endomètre localisé.

Recommendations for clinical practice, Nice/Saint-Paul-de-Vence 2022-2023: Management of localized endometrial cancer Endometrial cancer is the most frequent gynecological cancers in industrialized countries and its incidence increases. The newmolecularclassification allows determination of the risk of recurrence and helps orienting therapeutic management. Surgery remains the cornerstone of treatment. Minimally invasive approach must be preferred for stages I and II. Surgery includes hysterectomy with bilateral adnexectomy, sentinel lymph node biopsy even in high risk diseases and omentectomy for non-endometrioid tumors (except in case of clear cells tumors). Fertility preservation can be proposed in low grade, stage I tumors without myometrial involvement. In stage III/IV disease, lymph node debulking without totallymphadenectomy is indicated. In case of peritoneal carcinomatosis, first-line cytoreductive surgery is recommended if complete resection can be achieved. Adjuvant therapy is not recommended in low risk tumors. In intermediate risk tumors, curietherapy is indicated. In tumors with high-intermediate risk, curietherapy and external radiotherapy are indicated according to prognostic factors (stage II, lymphovascular invasion); adjuvant chemotherapy can be considered on a case-by-case basis. In high risk tumors, chemotherapy and external radiotherapy are recommended using a concomitant or sequential approach.

Advances in adoptive T-cell therapy for metastatic melanoma.

Adoptive T cell therapy (ACT) is a fast developing, niche area of immunotherapy (IO), which is revolutionising the therapeutic landscape of solid tumour oncology, especially metastatic melanoma (MM). Identifying tumour antigens (TAs) as potential targets, the ACT response is mediated by either Tumour Infiltrating Lymphocytes (TILs) or genetically modified T cells with specific receptors - T cell receptors (TCRs) or chimeric antigen receptors (CARs) or more prospectively, natural killer (NK) cells. Clinical trials involving ACT in MM from 2006 to present have shown promising results. Yet it is not without its drawbacks which include significant auto-immune toxicity and need for pre-conditioning lymphodepletion. Although immune-modulation is underway using various combination therapies in the hope of enhancing efficacy and reducing toxicity. Our review article explores the role of ACT in MM, including the various modalities - their safety, efficacy, risks and their development in the trial and the real world setting.

ESGO/ESTRO quality indicators for radiation therapy of cervical cancer.

BACKGROUND: The European Society of Gynaecological Oncology (ESGO) has previously defined and established a list of quality indicators for the surgical treatment of cervical cancer. As a continuation of this effort to improve overall quality of care for cervical cancer patients across all aspects, ESGO and the European SocieTy for Radiotherapy and Oncology (ESTRO) initiated the development of quality indicators for radiation therapy of cervical cancer. OBJECTIVE: To develop a list of quality indicators for radiation therapy of cervical cancer that can be used to audit and improve clinical practice by giving to practitioners and administrators a quantitative basis to improve care and organizational processes, notably for recognition of the increased complexity of modern external radiotherapy and brachytherapy techniques. METHODS: Quality indicators were based on scientific evidence and/or expert consensus. The development process included a systematic literature search for identification of potential quality indicators and documentation of scientific evidence, consensus meetings of a group of international experts, an internal validation process, and external review by a large international panel of clinicians (n = 99). RESULTS: Using a structured format, each quality indicator has a description specifying what the indicator is measuring. Measurability specifications are detailed to define how the quality indicators will be measured in practice. Targets were also defined for specifying the level which each unit or center should be aiming to achieve. Nineteen structural, process, and outcome indicators were defined. Quality indicators 1-6 are general requirements related to pretreatment workup, time to treatment, upfront radiation therapy, and overall management, including active participation in clinical research and the decision making process within a structured multidisciplinary team. Quality indicators 7-17 are related to treatment indicators. Quality indicators 18 and 19 are related to patient outcomes. DISCUSSION: This set of quality indicators is a major instrument to standardize the quality of radiation therapy in cervical cancer. A scoring system combining surgical and radiotherapeutic quality indicators will be developed within an envisaged future ESGO accreditation process for the overall management of cervical cancer, in an effort to support institutional and governmental quality assurance programs.

ESGO/ESTRO/ESP Guidelines for the management of patients with cervical cancer - Update 2023.

In 2018, the European Society of Gynecological Oncology (ESGO) jointly with the European Society for Radiotherapy and Oncology (ESTRO) and the European Society of Pathology (ESP) published evidence-based guidelines for the management of patients with cervical cancer. Given the large body of new evidence addressing the management of cervical cancer, the three sister societies jointly decided to update these evidence-based guidelines. The update includes new topics to provide comprehensive guidelines on all relevant issues of diagnosis and treatment in cervical cancer. To serve on the expert panel (27 experts across Europe) ESGO/ESTRO/ESP nominated practicing clinicians who are involved in managing patients with cervical cancer and have demonstrated leadership through their expertise in clinical care and research, national and international engagement, profile, and dedication to the topics addressed. To ensure the statements were evidence based, new data identified from a systematic search was reviewed and critically appraised. In the absence of any clear scientific evidence, judgment was based on the professional experience and consensus of the international development group. Before publication, the guidelines were reviewed by 155 independent international practitioners in cancer care delivery and patient representatives. These updated guidelines are comprehensive and cover staging, management, follow-up, long-term survivorship, quality of life and palliative care. Management includes fertility sparing treatment, early and locally advanced cervical cancer, invasive cervical cancer diagnosed on a simple hysterectomy specimen, cervical cancer in pregnancy, rare tumors, recurrent and metastatic diseases. The management algorithms and the principles of radiotherapy and pathological evaluation are also defined.

ESTRO/ESGO/SIOPe Guidelines for the management of patients with vaginal cancer.

Primary vaginal malignancies are rare, comprising only 2% of all female genital tract malignancies in adults and 4.5% in children. As part of its mission to improve the quality of care for women with gynecological cancers across Europe, the European Society of Gynaecological Oncology (ESGO) jointly with the European Society for Radiotherapy & Oncology (ESTRO) and the European Society of Pediatric Oncology (SIOPe) developed evidence-based guidelines in order to improve the management of patients with vaginal cancer within a multidisciplinary setting.ESTRO/ESGO/SIOPe nominated practicing clinicians who are involved in the management of vaginal cancer patients and have demonstrated leadership through their expertise in clinical care and research, their national and international engagement and profile as well as dedication to the topics addressed to serve on the expert panel (13 experts across Europe comprising the international development group). To ensure that the statements were evidence based, the current literature was reviewed and critically appraised.In the case of absence of any clear scientific evidence, judgment was based on the professional experience and consensus of the international development group. Prior to publication, the guidelines were reviewed by 112 independent international practitionners in cancer care delivery and patient representatives and their comments and input were incorporated and addressed accordingly.These guidelines cover comprehensively the diagnostic pathways as well as the surgical, radiotherapeutical and systemic management and follow-up of adult patients (including those with rare histological subtypes) and pediatric patients (vaginal rhabdomyosarcoma and germ cell tumours) with vaginal tumours.
