BITS-TO-HCC Study: HAIC+Iparomlimab/Tuvonralimab + Bevacizumab + SBRT for BCLC-C HCC With PVTT and/or Oligometastases

This multicenter, prospective, single-arm Phase II clinical trial is designed to evaluate the efficacy and safety of combining bevacizumab plus iparomlimab/tuvonralimab with hepatic artery infusion chemotherapy (HAIC) followed by stereotactic body radiotherapy (SBRT) in patients with Barcelona Clinic Liver Cancer (BCLC) stage C hepatocellular carcinoma (HCC) who present with portal vein tumor thrombus (PVTT) or extrahepatic oligometastatic disease. The study aims to determine whether this combination strategy can prolong progression-free survival (PFS), while also improving overall survival (OS), objective response rate (ORR), disease control rate (DCR), and local control rate (LCR), as well as maintaining quality of life (QoL). In addition, the trial will systematically evaluate the safety profile and treatment-related toxicities associated with this regimen.

HPV After chemoRadioTherapy

The HART (HPV After chemoRadiotherapy) study is a prospective multicenter observational trial designed to evaluate the clinical utility of HPV testing in the follow-up of patients treated with definitive chemoradiotherapy (CRT) for cervical cancer. Current surveillance after CRT relies mainly on clinical examination and imaging, while the role of HPV-based molecular monitoring remains insufficiently defined. The study plans to enroll 120 patients with FIGO stage IB-IVA cervical cancer treated with primary radiotherapy with curative intent. HPV detection will be performed using two complementary approaches: PCR-based detection of HPV DNA from a cervical swab and analysis of circulating HPV tumor DNA (ctDNA) in peripheral blood. Samples will be collected before treatment and during follow-up at 3, 12, and 24 months after completion of CRT. The primary objective is to determine the sensitivity of these methods for detecting disease recurrence during a two-year follow-up period. Secondary objectives include evaluation of HPV clearance after treatment, comparison of HPV genotypes before and after therapy in cases of persistence, and comparison of the diagnostic performance of cervical HPV testing and ctDNA detection. The study aims to generate evidence supporting the integration of HPV-based molecular monitoring into routine follow-up, potentially enabling earlier detection of recurrence and more individualized surveillance strategies for patients after CRT for cervical cancer.

Level I-II Axillary Irradiation in Breast Cancer With Sentinel-Node Macro-metastases

The RELAX trial is an open-label, multicenter, non-inferiority, randomized, phase 3 clinical trial. Multiple randomized trials have demonstrated the safety of omitting complete axillary-lymph-node dissection in patients with invasive breast cancer and limited sentinel lymph node metastases. However, the necessity and optimal extent of regional nodal irradiation remains uncertain. The aim of this study is to evaluate whether level I-II axillary irradiation is non-inferior to whole regional nodal irradiation in terms of disease-free survival in clinically node-negative breast cancer patients with 1-2 sentinel lymph node macro-metastases.

Phase III, Multicenter, Randomized Controlled Clinical Study of Three-Dimensional Radiotherapy for Primary Tumors in Non-Oligometastatic Stage IV Non-Small Cell Lung Cancer

For patients with non-small cell lung cancer and more than five metastatic lesions (non-oligometastatic disease), does radical treatment of the primary lung lesion, in addition to pharmacotherapy, also provide benefits in terms of progression-free survival (PFS) and local control? Currently, there is limited clinical research on combining pharmacotherapy with radiotherapy for the primary lesion in non-oligometastatic patients. Therefore, this study aims to investigate whether radical radiotherapy targeting the primary lung lesion, in addition to pharmacotherapy, can improve local control and survival in non-oligometastatic patients, and whether the associated toxicities are acceptable.

Iparomlimab and Tuvonralimab Plus Hypofractionated Radiotherapy and Chemotherapy for HAHNSCC

Head and neck squamous cell carcinoma (HNSCC) is often diagnosed at a locally advanced stage, where cisplatin-based chemoradiotherapy is standard but still results in high recurrence rates. Immunotherapy is promising for HNSCC due to its high mutational burden, and adding PD-1 inhibitors to induction chemotherapy has improved responses without added toxicity. Radiotherapy can further stimulate antitumor immunity. Iparomlimab and Tuvonralimab, a dual anti-PD-1/CTLA-4 antibody, has shown strong activity across several solid tumors, and early studies suggest synergy with hypofractionated radiotherapy. However, evidence in locally advanced HNSCC is lacking. The investigators therefore propose a multicenter, single-arm phase II trial to assess the efficacy and safety of combining Iparomlimab and Tuvonralimab injection with chemoradiotherapy in locoregionally advanced HNSCC.

Cervical Cancer Oligo States (Recurrence, Metastasis) Multicentre Outcomes Study.

Systemic chemotherapy with or without palliative radiation represents the current standard of care in patients with recurrent or metastatic cervix cancer. In addition, pelvic radiotherapy including brachytherapy is also recommended. There is no consensus on the treatment of metastatic site in patients with oligo-metastatic or oligo-recurrent cervix cancer. Also, it is not clear if addition of local treatment to systemic chemotherapy benefits all patients with metastatic disease or a select few with limited systemic disease burden. It's presently unclear which patients derive maximum benefit with integration of radiation at both primary and metastatic site, who develop infield recurrence if performing salvage surgery, locally directed treatments or re-irradiation in addition to systemic chemotherapy improves overall outcomes. The heterogeneity in clinical practice provides an important opportunity to develop a framework for data collection and future studies within such subgroup of patients. In this retrospective study, we aim to determine overall survival, Infield progression free survival, overall progression free survival, dose response relationship of nodal and visceral progressions, and within setting of re-irradiation (infield progressions), severe adverse events and toxicity, risk groups identification, a nomogram which correlates risk groups with expected outcomes, and framework for tissue collection for translational research Investigators will record the parameters in a predesigned proforma without including personal identifiers.

MRinRT: Swansea University and SWWCC Collaboration Study.

The aim of this study is to learn whether using MRI (magnetic resonance imaging) scans to plan radiotherapy is better than using CT (computed tomography) scans alone. The main questions it aims to answer is: * Can MRI scan images be adjusted to make the tumour and normal tissues easier to see? * Does adding MRI to a radiotherapy planning CT make the radiotherapy plan more precise? * Can MRI be used to adjust a radiotherapy plan during a course of treatment to make it more precise, and might that reduce the side effects? * Are there particular MRI scans that can predict how a tumour will respond to radiotherapy or how likely the patient is to have side effects? This study will assess current MRI scanning procedures and ensure these are adjusted to best suit radiotherapy planning. It will also provide pilot data evaluating: 1. MRI-adapted radiotherapy Usually, radiotherapy plans are based on a pre-treatment planning CT scan. Unless an issue is detected the patient would complete their whole course of radiotherapy on this plan. This does not account for changes in position/size/shape of the tumour that occur over the whole treatment course. Clinicians therefore increase the size of the tumour/target to account for these uncertainties, which can increase side effects. This study will assess the potential to reduce side effects from radiotherapy by using repeat MRI scans and replanning during the treatment course (MRI-adaptive radiotherapy). 2. Imaging biomarkers MRI sequences can be used to predict response to radiotherapy or chance of developing side effects. This study will identify potential MRI sequences that may be used as imaging biomarkers, to guide the development of future clinical trials. The study will be undertaken at SBUHB, lasting 4 years, and involving ≤15 healthy volunteers and ≤150 patients.

Study of Prognostic Biomarkers of Survival at 6 Months for Patients Treated With Bevacizumab Glioblastomas in First Relapse After Failure of Radiochemotherapy

No predictive factors are known for the response to the bevacizumab anti-angiogenic molecule (Avastin) given in the event of relapse of glioblastoma (GBM) following radiochemotherapy. Classical MRI with gadolinium injection and perfusion is not sufficient to predict survival and response or duration. We propose to evaluate the prognostic interest for 6-month survival of spectroscopic biomarkers of proliferation, glial reaction, infiltration and glutaminergic metabolism or glycolytic metabolism recorded at 7 and 28 days of application of the treatment. These biomarkers are based on the increase of an index combining choline / Creatine (Cho / Cr), Glx / Cr (Glutamine and glutamate / Creatine), NAA / Cr (N acetyl aspartate / Creatine) and lactate / Cr ratios. The long-term objective is to predict the survival of these relapsed GBM patients at an early stage and to identify responder patients who would benefit from this expensive molecule and avoid using it in non-responding patients

Intestinal Low-Dose Radiotherapy Plus Immunochemotherapy for Conversion of Borderline Resectable/Unresectable Esophageal Squamous Cell Carcinoma

Esophageal cancer (EC) ranks among the leading malignant gastrointestinal tumors globally in terms of both incidence and mortality. Cases of EC in China account for over 50% of the global total, with squamous cell carcinoma being the primary pathological type. Locally advanced EC (LAEC), particularly cases where radical surgical resection is not feasible, exhibits high recurrence rates and low 5-year survival rates. However, studies have shown that patients with LAEC who undergo comprehensive treatment followed by surgery experience significantly prolonged survival and improved quality of life compared to those who do not receive surgical intervention. Current conversion treatment regimens under investigation include: chemotherapy alone, chemoradiotherapy, immunotherapy combined with chemotherapy, and immunotherapy combined with chemoradiotherapy-each of these approaches has distinct advantages and limitations. Immunochemotherapy has emerged as a current research focus: it not only demonstrates significantly superior efficacy compared to chemotherapy alone but also exhibits lower cumulative toxicity than radiotherapy-combined conversion regimens, resulting in a more favorable overall benefit-risk ratio. As such, it represents the most promising conversion treatment strategy. Retrospective and prospective clinical studies have shown that low-dose radiotherapy targeting the small intestine can enhance the anti-tumor response of immune checkpoint inhibitors (ICIs) in patients with advanced solid tumor, prolong their overall survival, and increase the incidence of the abscopal effect. Further mechanistic investigations have revealed that intestinal low-dose radiotherapy (ILDR) may augment the immune cancerous lethality by modulating the gut microbiota and their metabolic profiles. Based on the findings from these preliminary studies, the current research plans to conduct a prospective phase II single-arm clinical trial to investigate the efficacy and safety of ILDR combined with immunochemotherapy as conversion therapy in patients with borderline resectable or unresectable esophageal squamous cell carcinoma (BR/UR ESCC). This research plans to enroll at least 39 evaluable cases or a total of 43 cases in two seperated stages, focusing on patients with thoracic BR/UR ESCC. Patients will receive a single fraction of ILDR with a mean dose of 1 Gy, concurrently with 3 cycles of albumin-bound paclitaxel (260 mg/m² on day 1), cisplatin (75 mg/m² on day 1), and tislelizumab (200 mg on day 1). The efficacy and safety of the treatment will be evaluated throughout the study.

A Phase II Study Assessing Stereotactic Radiotherapy in Therapeutic Strategy of Oligoprogressive Renal Cell Carcinoma Metastases

Every year, 12500 primary renal cell carcinoma (RCC) are diagnosed in France. Metastases occur in half of RCC patients. Management of metastatic RCC is based on systemic treatments (targeted therapies/immunotherapy). However, resistance to systemic treatment is frequent. In case of progression, usual therapeutic attitude is initiating another systemic therapy. Because of the emergence of resistant tumor clonal cells, some patients progress only on few sites while the rest of tumor burden is controlled. In this setting named oligoprogressive disease \[isolated progression of \<3-5 metastase(s)\], ablative treatments of these evolving metastatic sites could allow a disease control and a reduced risk of new metastases occurrence by tumor-cell reembolization. Such strategy is challenging to prolong ongoing systemic treatment and delay further lines. Although RCC was considered radioresistant and radiotherapy with conventional fractionation was mainly used for palliation of symptoms, stereotactic radiotherapy (SRT), by delivering high dose in one or few fractions, allows local control for about 90% of RCC metastases through various radiobiological pathways. Furthermore, some data suggest that high-dose focal irradiation of RCC could induce a systemic antitumor response mediated by immunologic effectors(1). This phenomenon ("abscopal effect") could be enhanced in patients under immunotherapy, including anti-PD1. Several retrospective studies and one non-randomized phase-II study highly suggest the interest of SRT as focal ablative treatment in RCC oligometastases with excellent local control rates and low toxicity(2,3). Furthermore, the multicentric retrospective study the sponsor recently conducted within the GETUG group among 101 metastatic RCC patients with oligoprogression under systemic therapy highlighted that SRT on progressive sites provided a median of 8.6-month progression-free survival and allowed to continue current systemic line for 10.5 months. However, to date, there are no prospective data assessing the interest of SRT for management of oligoprogressive metastatic RCC. The sponsor aim to prospectively evaluate the interest of SRT as a therapeutic strategy for local control of oligoprogressive metastatic RCC under ongoing systemic treatment, and consequently delay subsequent systemic treatment.

Node-Sparing Hypofractionated Radiotherapy Plus Chemotherapy and PD-1 Inhibitor in pMMR/MSS High-Risk Locally Advanced Colon Cancer: A Prospective, Randomized, Phase II Trial

Most colorectal cancers are microsatellite stable (MSS) or mismatch repair-proficient (pMMR) subtypes, which show limited efficacy to PD-1 inhibitors. Radiotherapy can enhance the release of tumor-associated antigens, thereby improving the responsiveness of pMMR/MSS colorectal cancers to PD-1 blockade. Tumor-draining lymph nodes (TDLNs) are critical sites where PD-1 inhibitors exert their antitumor effects; however, previous studies have reported that direct radiation-induced damage and fibrosis may impair lymphatic drainage and antitumor immunity. Early reports have demonstrated a remarkable pathological complete response (pCR) rate of 77.8% with lymph node-sparing short-course radiotherapy (25 Gy in 5 fractions) in locally advanced rectal cancer. In metastatic colorectal cancer, single-fraction high-dose irradiation (6-8 Gy) has been shown to induce robust abscopal effects. Based on these findings, our study aims to evaluate whether lymph node-sparing hypofractionated radiotherapy (25 Gy/5F or 24 Gy/4F) followed sequentially by chemotherapy and PD-1 blockade can increase the pCR rate, improve tolerability, and ultimately enhance outcomes in patients with pMMR/MSS high-risk locally advanced colon cancer.
