Abstract
Androgen deprivation therapy (ADT) is a mainstay of treatment for metastatic prostate cancer, while additional salvage radiotherapy may offer prolonged remission for patients with regional node relapses. We report 5-yr outcomes from OLIGOPELVIS (GETUG-P07), an open-label phase 2 trial assessing long-term outcomes and patterns of relapse after 6-mo ADT and elective nodal radiotherapy (ENRT) in men with pelvic nodal oligorecurrence (<6 lesions) of prostate cancer. Progression was defined as two consecutive prostate-specific antigen (PSA) levels above the level at inclusion and/or clinical progression according to Response Evaluation Criteria in Solid Tumors v1.1 and/or death from any cause. Sixty-seven patients were recruited. Median follow-up was 6.1 yr (95% confidence interval 5.9-6.3). Rates of grade 2+ toxicities among patients without progression at 3, 4, and 5 yr were 15%, 9%, and 4% for genitourinary toxicities, and 2%, 3%, and 4% for gastrointestinal toxicities, respectively. The 5-yr progression-free, biochemical relapse-free, and ADT-free survival rates were 39%, 31%, and 64%, respectively. In total, 45 patients experienced progression, which was PSA-only progression in seven cases. Among the other 38 patients, local clinical progression occurred in 18%, progression to N1 stage in 29%, to M1a stage in 50%, to M1b stage in 32%, and to M1c stage in 11%. Finally, combined ENRT and ADT appeared to prolong tumor control with limited toxicity. At 5 yr, one-third of the patients had not experienced biochemical relapse. The major site of relapse was the para-aortic lymph nodes. PATIENT SUMMARY: We evaluated long-term results for high-dose radiotherapy in patients with recurrence of prostate cancer in pelvic lymph nodes. We found that this treatment provided prolonged tumor control without significant toxicity. One-third of the patients were still in complete remission after 5 years.

Abstract
There are currently no accurate rules for manually delineating the subregions of the heart (cavities, vessels, aortic/mitral valves, Planning organ at Risk Volumes for coronary arteries) with the perspective of deep-learning based modeling. Our objective was to present a practical pictorial view for radiation oncologists, based on the RTOG atlas and anatomical complementary considerations for the cases where the RTOG guidelines are missing.

Abstract
Aim The adrenal gland is a common site of metastasis with a rate of up to 27% in autopsy series. The incidence of these metastases is increasing due to greater use of Positron Emission Tomography scans and improved overall survival of patients with metastatic cancers. Stereotactic body radiation therapy (SBRT) is a non-invasive treatment option for metastasis. The aim of this study is to assess prognostic factors influencing local control, progression-free and overall survival in oligometastatic patients treated with SBRT for an adrenal metastasis. Methods In this multicentric retrospective study, we included patients with adrenal metastases treated with SBRT between 2010 and 2021 in eleven french centers. All primary tumors were included. Results A total of 110 patients treated for 121 adrenal lesions were included. Non-small-cell lung cancer was the predominant histologic type (55.4 %). Eighty-two percent of patients had at least 2 metastatic sites. The median Planning Target Volume was 70 cm3 with a median prescription dose of 40 Gray (Gy). The mean Biologically Effective Dose (BED) 10 dose was 74.2 Gy. Local control at 1 and 2 years was 85.9 % and 72.5 % respectively. The median overall survival and progression-free survival were 31.6 and 8.5 months respectively. Local control was significantly improved by systemic treatment one month before or after SBRT (p = 0.009) and by a BED10 greater than or equal to 50 Gy (p = 0.003).In multivariate analysis, oligometastatic presentation (p = 0.009) and a metachronous metastatic presentation (p = 0.008) were independent factors for progression-free survival.Tolerance was excellent, no grade 3 and 4 toxicities were described due to SBRT. Conclusion Stereotactic radiotherapy of adrenal metastases makes possible a local control of more than 85% at one year and was well tolerated. The factors influencing survival in oligometastatic patients still need to be found in order to better select those who benefit the most from this type of treatment.

Abstract
BACKGROUND First-line chemotherapy plus immunotherapy (CT-IO) has recently demonstrated survival benefits over CT alone in extensive-stage small-cell lung cancer (ES-SCLC), based on randomized phase III studies. This retrospective multicenter study assessed the real-world use and effectiveness of CT-IO in ES-SCLC patients. PATIENTS AND METHODS All newly diagnosed ES-SCLC patients from 4 French hospitals treated with CT alone or CT-IO between May 2020 and December 2021 were included. Overall survival (OS) and real-world progression-free survival (rwPFS) were estimated using the Kaplan-Meier method. Cox proportional hazard models were performed to estimate hazard ratios (HRs) with 95 % confidence intervals (CIs) in univariate and multivariate models. The aim was not to compare efficacy between groups. RESULTS Among 104 patients, 75 (72.1%) received CT-IO. Brain metastases were diagnosed in 28.3% of patients, and 29.8% were performance status (PS) ≥ 2. At a median follow-up of 16.8 months (95%CI, 14.9-23.4), the median OS was 11.4 months (95%CI, 7.7-14.7) in the CT-IO group, and the 12-month OS rate was 43.6% (95%CI, 33.3-57.2). In the CT group, the median OS was 7.8 months (95%CI, 5.4-11.8) and the 12-month OS rate was 15.3% (95%CI, 5.7-41.0). In multivariate analyses, baseline brain and liver metastases were associated with a shorter OS for patients treated in the CT-IO group (HR, 3.80 [95%CI, 1.90-7.60] and 3.12 [95%CI, 1.60-6.08] respectively; P < 0.001 for both). CONCLUSION We showed that clinicians have chosen to use IO beyond the specific criteria defined in guidelines. Survival data appeared promising with a median OS comparable to the one previously demonstrated in clinical trials.

Abstract
BACKGROUND Patients with glioblastomas have a dismal prognosis, and there is no circulating predictive or prognostic biomarker. Circulating progastrin, hPG80, is a tumor-promoting peptide present in the blood of patients with various cancers that has been shown to have prognostic value. We evaluated the prognostic value of plasma hPG80 in patients with isocitrate dehydrogenase-wild type glioblastoma after surgery. PATIENTS AND METHODS A multicentric retrospective study in glioblastoma patients treated with standard radio-chemotherapy was conducted. The hPG80 levels were measured in plasma EDTA samples collected after surgery with an ELISA DxPG80.lab kit (Biodena Care, Montpellier, France), which has a detection threshold of 1.2 pM. The relationship between post-operative hPG80 plasma levels, in combination with other known prognostic factors, and patients' progression-free survival (PFS) and overall survival (OS) was evaluated. RESULTS Sixty-nine patients were assessable. Plasma samples were collected after tumor biopsy (B), partial resection (PR), and complete resection (CR) for 22, 25, and 22 patients, respectively. At a median concentration of 5.37 pM (interquartile range 0.00-13.90 pM), hPG80 was detected in 48 (70%) patients (hPG80+). CR was associated with significant lower values of hPG80 levels: the median value was 0.7 versus 9.1 pM for PR (P = 0.02) and 8.3 pM for B (P = 0.004). The hPG80 detection rate was also significantly lower: 50% (CR) versus 72% (PR) versus 86% (B) (P = 0.005). The median follow-up was 39 months [22.4 months-not reached]. hPG80 post-operative detection was associated with numerically shorter PFS (6.4 versus 9.4 months, P = 0.13) and OS (14.5 versus 20.9 months, P = 0.11). In multivariate analysis, hPG80 was a prognostic factor for OS (P = 0.034). CONCLUSIONS Circulating hPG80 could serve as a new prognostic biomarker after surgery in patients with glioblastoma treated with radio-chemotherapy.

Abstract
Radiation therapy in the thoracic region may deliver incidental ionizing radiation to the surrounding healthy structures, including the heart. Radio-induced heart toxicity has long been a concern in breast cancer and Hodgkin's lymphoma and was deemed a long-term event. However, recent data highlight the need to limit the dose to the heart in less favorable thoracic cancers too, such as lung and esophageal cancers in which incidental irradiation led to increased mortality. This article will summarize available cardiac dose constraints in various clinical settings and the types of radio-induced cardiovascular diseases encountered as well as delineation of cardiac subheadings and management of cardiac devices. Although still not completely deciphered, heart dose constraints remain intensively investigated and the mean dose to the heart is no longer the only dosimetric parameter to consider since the left anterior descending artery as well as the left ventricle should also be part of dosimetry constraints.

Abstract
The sentinel lymph node technique is minimally invasive and used routinely by surgeons, reducing the need for morbid extensive lymph node dissections, which is a significant advantage for cancer staging and treatment decisions. The sentinel lymph node could also help radiation oncologists to identify tumor drainage for each of their patients, leading to a more personalized radiotherapy, instead of a probabilistic irradiation based on delineation atlases. The aim is both to avoid recurrence in unexpected areas and to limit the volume of irradiated healthy tissues. The aim of our study is to evaluate the impact of sentinel lymph node mapping for radiation oncologists. This concept, relying on sentinel lymph node mapping for treatment planning, is known as lymph-flow-guided radiotherapy. We present an up-to-date narrative literature review showing the potential applications of the sentinel lymph node technique for radiotherapy, as well as the limits that need to be addressed before its routine usage.

Abstract
Translational research in radiation oncology is undergoing intense development. An increasingly rapid transfer is taking place from the laboratory to the patients, both in the selection of patients who can benefit from radiotherapy and in the development of innovative irradiation strategies or the development of combinations with drugs. Accelerating the passage of discoveries from the laboratory to the clinic represents the ideal of any translational research program but requires taking into account the multiple obstacles that can slow this progress. The ambition of the RadioTransNet network, a project to structure preclinical research in radiation oncology in France, is precisely to promote scientific and clinical interactions at the interface of radiotherapy and radiobiology, in its preclinical positioning, in order to identify priorities for strategic research dedicated to innovation in radiotherapy. The multidisciplinary radiotherapy teams with experts in biology, medicine, medical physics, mathematics and engineering sciences are able to meet these new challenges which will allow these advances to be made available to patients as quickly as possible.

Abstract
2049 Background: hPG80 (circulating progastrin) is a protein secreted by many cancer types, playing a role in tumorigenesis by regulating cancer stem cells, angiogenesis, proliferation/differentiation and decreasing apoptosis. hPG80 is detectable in plasma of cancer patients and previous studies have shown its prognostic role in various cancers. Given the lack of circulating biomarker in glioblastoma, we evaluated the prognostic value of plasma hPG80 in patients with IDH wild type glioblastoma Methods: This multicentric retrospective study included IDHwt glioblastoma patients treated with standard radio-chemotherapy. The ELISA DxPG80.lab kit (Biodena Care, Lausanne, Switzerland) was used to measure hPG80 levels after surgery with a detection threshold of 1 pM in all plasma EDTA samples according to the manufacturer’s instruction. The prognostic impact of hPG80 was evaluated on patient’s progression-free survival (PFS) and overall survival (OS). Results: We included 70 patients (38 males /32 women) with a median age of 64 years (Range 19 - 84). Karnofsky index was > 70% in 52 (91%) of 57 evaluable patients. Tumor biopsy (B), partial resection (PR), complete resection (CR) were performed in 22, 25 and 23 patients respectively. MGMT promotor was methylated in 22 (40%) of the 55 evaluable patients. After surgery, hPG80 was detected in 48 (69%) patients (hPG80+) with a median concentration of 9.52 pM (IQR 5.21 - 21.20). Complete surgery was associated with undetectable levels of hPG80 (52% (CR) vs 28% (PR) vs 14% (B), p = 0.006) and lower concentration if hPG80+ (CR: 5.8 pM [IQR 1.92 - 11.38] vs PR: 12.84 pM [IQR 8.09 - 37.09]; p = 0.04 vs B: 9.86 pM [IQR 4.66 - 21.63]; p = 0.16). With a median follow-up of 39 months (22.4-NR), 86% of patients had progressed and 70% had died. In univariate analysis, hPG80 positivity was associated with PFS (5.6m vs 8.5m, p = 0.053) and OS (14.5 vs 22m, p = 0.04) in hPG80+ vs hPG80- patients respectively. hPG80+ patients with complete surgery had worse median OS than hPG80- patients (14.5 vs 22.0 m; p = 0.051 respectively. Cox proportional hazards model did not fit for covariate analysis. Conclusions: Our findings show that hPG80 could serve as a new circulating prognostic biomarker in IDHwt glioblastoma patients treated with radio-chemotherapy. Further explorations are ongoing in larger cohorts including longitudinal evaluation during the course of the disease.

Abstract
Prostate cancer recurrence in patients previously treated with radical prostatectomy and radiation therapy is challenging. Re-irradiation could be an option, but data regarding efficacy and safety are lacking. We retrospectively evaluated salvage re-irradiation for local recurrence after prostatectomy and external beam radiation therapy. We collected data from 48 patients who underwent salvage reirradiation with stereotactic radiation therapy for local prostate cancer recurrence in the prostatic bed at four French centers. Fifteen patients (31%) were on androgen deprivation therapy during stereotactic radiotherapy. Biochemical response and relapse-free survival were analyzed, and post-treatment toxicities were assessed according to the Common Terminology of Adverse Events criteria. Five patients had grade 3 late bladder toxicity (cystitis), three had grade 3 late incontinence, and one had grade 3 late chronic pain. At three months, 83% of patients had a positive biochemical response. The median follow-up was 22 months. At the end of the follow-up, 21 patients (43%) had a biochemical relapse. The median time to biologic relapse was 27 months. The biochemical relapse rates at 1 and 2 years were 80% and 52%, respectively. In conclusion, salvage re-irradiation for recurrent prostate cancer in the prostate bed may generate significant toxicity rates, and a prospective study with appropriate patient selection is needed to evaluate its effectiveness.

Abstract
BACKGROUND Oligorecurrent pelvic nodal relapse in prostatic cancer is a challenge for regional salvage treatments. Androgen depriving therapies (ADTs) are a mainstay in metastatic prostate cancer, and salvage pelvic radiotherapy may offer long ADT-free intervals for patients harboring regional nodal relapses. OBJECTIVE To assess the efficacy of the combination of ADT and salvage radiotherapy in men with oligorecurrent pelvic node relapses of prostate cancer. DESIGN, SETTING, AND PARTICIPANTS We performed an open-label, phase II trial of combined high-dose intensity-modulated radiotherapy and ADT (6 mo) in oligorecurrent (five or fewer) pelvic node relapses in prostate cancer, detected by fluorocholine positron-emission tomography computed tomography imaging. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The primary endpoint was 2-yr progression-free survival defined as two consecutive prostate-specific antigen levels above the level at inclusion and/or clinical evidence of progression as per RECIST 1.1 and/or death from any cause. RESULTS AND LIMITATIONS Between August 2014 and July 2016, 67 patients were recruited in 15 centers. Half of the patients had received prior prostatic irradiation. The median age was 67.7 yr. After a median follow-up of 49.4 mo, 2- and 3-yr progression-free survival rates were 81% and 58%, respectively. Median progression-free survival was 45.3 mo. The median biochemical relapse-free survival (BRFS) was 25.9 mo. At 2 and 3 yr, the BRFS rates were 58% and 46%, respectively. Grade 2 + 2-yr genitourinary and gastrointestinal toxicities were 10% and 2%, respectively. CONCLUSIONS Combined high-dose salvage pelvic radiotherapy and ADT appeared to prolong tumor control in oligorecurrent pelvic node relapses in prostate cancer with limited toxicity. After 3 yr, nearly half of patients were in complete remission. Our study showed initial evidence of benefit, but a randomized trial is required to confirm this result. PATIENT SUMMARY In this report, we looked at the outcomes of combined high-dose salvage pelvic radiotherapy and 6-mo-long hormone therapy in oligorecurrent pelvic nodal relapse in prostatic cancer. We found that 46% of patients presenting with oligorecurrent pelvic node relapses in prostate cancer were in complete remission after 3 yr following combined treatment at the cost of limited toxicity.

Abstract
OBJECTIVES The duration of stereotactic body radiotherapy (SBRT) for early-stage non-small cell lung cancer (NSCLC) may affect patient outcomes. We aimed to determine the impact of a continuous versus discontinuous SBRT schedule on local control (LC) and overall survival (OS) in NSCLC patients. MATERIALS AND METHODS Consecutive NSCLC stage I patients (475) treated with SBRT in four centers were retrospectively analyzed. The delivered dose ranged from 48 to 75 Gy in 3-10 fractions. Based on the ratio between the treatment duration (TD) and number of fractions (n), patients were divided into two groups: continuous schedule (CS) (TD ≤ 1.6n; 239 patients) and discontinuous schedule (DS) (TD > 1.6n; 236 patients). LC and OS were compared using Cox regression analyses after propensity score matching (216 pairs). RESULTS The median follow-up period was 41 months. Multivariate analysis showed that the DS (hazard ratio (HR): 0.42; 95 % confidence interval (CI): 0.22-0.78) and number of fractions (HR: 1.24; 95 % CI: 1.07-1.43) were significantly associated with LC. The DS (HR: 0.67; 95 % CI: 0.51-0.89), age (HR: 1.02; 95 % CI: 1-1.03), WHO performance status (HR: 2.27; 95 % CI: 1.39-3.7), and T stage (HR: 1.4; 95 % CI: 1.03-1.87) were significantly associated with OS. The 3-year LC and OS were 92 % and 64 % and 81 % and 53 % for DS and CS treatments, respectively (p < 0.01). Cox analysis confirmed that the discontinuous SBRT schedule significantly increased LC and OS. CONCLUSION DS is associated with significantly improved LC and OS in early-stage NSCLC patients treated with SBRT.

Abstract
We describe the clinical, electroencephalography (EEG), and developmental features of a patient with developmental and epileptic encephalopathy due to a homozygous pathogenic variation of mitochondrial glutamate/H+ symporter SLC25A22. Epilepsy began during the first week of life with focal onset seizures. Interictal EEG revealed a suppression-burst pattern with extensive periods of non-activity. The prospective follow-up confirmed developmental encephalopathy as well as ongoing active epilepsy and almost no sign of development at 8 years of age. We confirm in the following paper that SLC25A22 recessive variations may cause a severe developmental and epileptic encephalopathy characterized by a suppression-burst pattern. On the basis of an in-depth literature review, we also provide an overview of this rare genetic cause of neonatal onset epilepsy.

Abstract
93 Background: Oligorecurrent pelvic nodal relapse of prostatic cancer is a challenge for regional salvage treatments. We conducted OLIGOPELVIS – GETUG P07, a phase II trial of combined salvage radiotherapy and hormone therapy in oligorecurrent pelvic node relapses of prostate cancer (NCT02274779). Methods: OLIGOPELVIS–GETUG P07 was a prospective multi-center phase II trial investigating high-dose salvage pelvic irradiation with an additional dose to the fluorocholine-based positron-emission-tomography (FCH- PET)-positive pelvic lymph nodes (PLN), combined with six-month androgen blockade (LH-RH agonist or antagonist injections). The prescribed dose was 54 Gy in 1.8 Gy fractions with up to 66 Gy in 2.2 Gy fractions to the pathological PLN. Toxicity (CTCAE v4) and complete response rates (PSA < 0.20 ng/ml) were analyzed. The main objective was to assess biochemical-clinical failure defined by a cluster of events including PSA progression (≥25 % and ≥ 2 ng/ml above the nadir) or clinical evidence of local or metastatic progression or post- treatment initiation of hormonal therapy or prostate cancer-related death. We hypothesized that salvage treatment would achieve a 2-year relapse-free survival of 70 %. Results: Seventy-four patients were recruited in fifteen French radiation oncology departments between August 2014 and July 2016. Seven were excluded before treatment because of violation of the inclusion criteria. The intention-to-treat analysis therefore included sixty-seven patients. Half of them had received prior prostatic/prostate bed irradiation. Median age was 67.7. Grade 2+ two-year urinary and intestinal toxicity were 10% and 2% respectively. At 2 and 3 years, 73.1 and 45.9% of patients achieved a persisting complete response respectively. After a median follow-up of 34 months, the 2-year progression-free survival rate was 77.6%. Median progression-free survival was 40.1 months. Conclusions: Combined pelvic salvage radiotherapy and hormone therapy allowed for prolonged tumor control in oligorecurrent pelvic node relapses of prostate cancer with limited toxicity. Clinical trial information: NCT02274779.

Abstract
PURPOSE Limited pelvic nodal relapse of prostatic cancer is a paramount challenge for locoregional salvage treatments. Salvage whole pelvis radiation therapy as considered in the BLINDED trial is an attractive option, but there are concerns about its toxicity. This article describes early toxicity with the technique. METHODS AND MATERIALS BLINDED was a prospective multicenter phase 2 trial investigating high-dose salvage pelvic irradiation with an additional dose to the fluorocholine-based positron emission tomography-positive pelvic lymph nodes, combined with 6-month androgen blockade. The prescribed dose was 54 Gy in 1.8 Gy fractions with up to 66 Gy in 2.2 Gy fractions to the pathologic pelvic lymph nodes. Early toxicity was defined as toxicity until 1 year after radiation therapy. Patients quality of life was assessed using the European Organisation for Research and Treatment of Cancer questionnaires (QLQ-C30 and QLQ-PR25). RESULTS Seventy-four patients were recruited in 15 French radiation oncology departments between August 2014 and July 2016. Seven were excluded before treatment because of violation of the inclusion criteria. The intention-to-treat analysis therefore included 67 patients. Half had received prior prostatic irradiation. Median age was 67.7 ± 6.5 years. Grade 2 acute urinary toxicity was observed in 9 of 67 patients (13.4%), and grade 2 1-year toxicity occurred in 4 of 67 patients (6%). Three patients (4.4%) had grade 3 urinary toxicity. Grade 2 acute digestive toxicity was observed in 10 of 67 patients (14.9%), and grade 2 1-year toxicity occurred in 4 of 67 patients (6%). Patients with prior prostate bed irradiation did not exhibit increased urinary or digestive toxicity. The European Organisation for Research and Treatment of Cancer questionnaire scores at 1 year did not worsen significantly. CONCLUSIONS The acute and 1-year toxicity of the BLINDED protocol was satisfactory, even in patients with a history of prostatic irradiation.

Abstract
The determination of the effective Coulomb interactions to be used in low-energy Hamiltonians for materials with strong electronic correlations remains one of the bottlenecks for parameter-free electronic structure calculations. We propose and benchmark a scheme for determining the effective local Coulomb interactions for charge-transfer oxides and related compounds. Intershell interactions between electrons in the correlated shell and ligand orbitals are taken into account in an effective manner, leading to a reduction of the effective local interactions on the correlated shell. Our scheme resolves inconsistencies in the determination of effective interactions as obtained by standard methods for a wide range of materials, and allows for a conceptual understanding of the relation of cluster model and dynamical mean field-based electronic structure calculations.

Abstract
Systems of adatoms on semiconductor surfaces display competing ground states and exotic spectral properties typical of two-dimensional correlated electron materials which are dominated by a complex interplay of spin and charge degrees of freedom. We report a fully ab initio derivation of low-energy Hamiltonians for the adatom systems Si(111):X, with X=Sn, Si, C, Pb, that we solve within self-consistently combined GW and dynamical mean-field theory. Calculated photoemission spectra are in agreement with available experimental data. We rationalize experimentally observed trends from Mott physics toward charge ordering along the series as resulting from substantial long-range interactions.

Abstract
We provide a prescription for constructing Hamiltonians representing the low-energy physics of correlated electron materials with dynamically screened Coulomb interactions. The key feature is a renormalization of the hopping and hybridization parameters by the processes that lead to the dynamical screening. The renormalization is shown to be non-negligible for various classes of correlated electron materials. The bandwidth reduction effect is necessary for connecting models to materials behavior and for making quantitative predictions for low-energy properties of solids.
