A Prospective, Single-Arm Clinical Study of a Dietary Supplement for the Prevention of Acute Radiation-Induced Rectal Injury During Neoadjuvant Chemoradiotherapy for Rectal Cancer

This clinical study is a prospective, single-arm, single-center trial aimed at assessing the safety and efficacy of tributyrin (TB) as a dietary supplement for preventing acute radiation-induced rectal injury (ARII). Approximately 23 participants with locally advanced rectal cancer will receive tributyrin in addition to standard neoadjuvant chemoradiotherapy. We hypothesize that tributyrin will reduce the incidence of grade 2 or higher ARII, graded according to the RTOG/EORTC criteria. Treatment-related adverse events will be assessed using the Common Terminology Criteria for Adverse Events (CTCAE), and changes in health-related quality of life and bowel function will be assessed using the EORTC QLQ-C30 and IBD-Q questionnaires.

Association Between Clinical Classification and Prognosis in Chronic Radiation Enteropathy

This is a prospective, observational study aimed at exploring the associations between the clinical classification of chronic radiation enteropathy and prognosis. The study is planed to commence in November 2025 and prospectively observe 150 patients. During the study period, researchers will not intervene in clinical treatment decisions but will only collect patient clinical information, intestinal endoscopy/imaging/pathological data, test results, and follow-up data. The study results will fill the evidence gap in this field, advance the diagnosis and treatment of chronic radiation enteropathy, and provide scientific support for improving the prognosis of similar patients.

Serial MRI Scans During Radiation Therapy

This is a phase 1 study to determine the feasibility and utility of using serial magnetic resonance imaging (MRI) to assess treatment response during and after radiation therapy (standard of care cancer treatment) for participants with advanced esophageal cancer, glioblastoma, prostate cancer, vulvar cancer or pediatric glioma. The research study procedures include three MRI scans (one before, one during, and one after standard of care cancer radiation therapy) for participants with advanced esophageal cancer, glioblastoma, prostate cancer, vulvar cancer or pediatric glioma. The research study procedures include: * Screening for eligibility * Three MRI scans

Short-Course Radiotherapy Followed by CAPOX With or Without Iparomlimab and Tuvonralimab in pMMR/MSS Locally Advanced Rectal Cancer

This multicenter, randomized, controlled, phase III trial evaluates whether adding iparomlimab and tuvonralimab injection to CAPOX consolidation chemotherapy after short-course radiotherapy improves tumor response in patients with treatment-naive, proficient mismatch repair/microsatellite-stable (pMMR/MSS) locally advanced rectal adenocarcinoma. Eligible patients will be randomly assigned in a 1:1 ratio to receive short-course radiotherapy followed by CAPOX plus iparomlimab and tuvonralimab, or short-course radiotherapy followed by CAPOX alone. After total neoadjuvant therapy, patients with a clinical complete response may undergo a Watch-and-Wait strategy, whereas other patients will undergo total mesorectal excision according to standard clinical practice. The primary endpoint is complete response rate, defined as pathologic complete response after surgery or clinical complete response sustained for more than 1 year. Secondary endpoints include 3-year relapse-free survival, 3-year overall survival, sphincter preservation rate, and grade 3-4 acute adverse events. Exploratory analyses will assess tissue and blood biomarkers associated with treatment response.

Assessment of Adebelizumab Combined With Chemotherapy in Concurrent Radiotherapy Versus Sequential Radiotherapy as First-Line Treatment for Extensive-Stage Small Cell Lung Cancer

Immunotherapy combined with chemotherapy has emerged as the standard of care for patients with extensive-stage small cell lung cancer (ES-SCLC). The incorporation of thoracic radiotherapy can enhance treatment efficacy. Currently, the main types of research investigating immunotherapy combined with thoracic radiotherapy for untreated ES-SCLC are concurrent radiotherapy and sequential radiotherapy. The aim of this study is to evaluate the efficacy of adebelizumab in combination with chemotherapy, when administered concurrently with radiotherapy versus sequentially with radiotherapy, as a first-line treatment for ES-SCLC.

Dietary Supplements to Treat Radiation-Induced Rectal Injury

This clinical study is a prospective, single-arm, single-center trial aimed at assessing the safety and efficacy of tributyrin (TB) as dietary supplements in the treatment of chronic radiation-induced rectal injury (RRI). We hypothesize that these supplements will help improve rectal bleeding symptoms and elevate the quality of life for patients. The study will test whether the supplements can lower the LENT-SOMA scales of rectal bleeding and enhance overall patient health. Efficacy will be evaluated through blood tests and other non-invasive methods, ensuring patient safety and comfort throughout the study.

Longitudinal Multimodal Response Assessment During Neoadjuvant Treatment of Rectal Cancer

This pilot study aims to trial multimodal early response assessment to enable therapy adaptions in the context of non-operative therapy strategies of locally advanced rectal cancer (LARC) for development of a non-invasive response prediction model.

Music Therapy's Effect on Cancer Patients Undergoing Radiotherapy

The goal of this randomized controlled clinical study is to learn about the effects of music therapy on anxiety, stress, pain, and patient satisfaction in cancer patients who are newly starting radiotherapy (radiation treatment). The main questions it aims to answer are: Can music therapy lower the levels of anxiety and stress in patients receiving radiotherapy? Can music therapy improve the pain felt during the radiotherapy experience and overall satisfaction? Researchers will compare patients receiving standard radiotherapy (control group) with patients receiving music therapy alongside their radiotherapy (experimental group). Participants (72 total) will: Be 18 years and older and newly starting curative radiotherapy. Answer short surveys (STAI-SF, SDT, VAS) to measure their anxiety, stress, and pain levels before and after treatment. Participants in the experimental group will receive a 15-20 minute music therapy session consisting of meditative and instrumental music during their first radiotherapy session. This study aims to provide reliable data to guide clinical practice by showing whether music therapy offers a multifaceted approach to managing the psychological and physical challenges associated with cancer treatment.

Quantitative Marrow Imaging, Marrow Reserve, And Clinical Outcomes In Patients Undergoing Radiotherapy For Hematologic And Related Disorders

To create a registry for people who are undergoing or previously underwent radiotherapy for hematologic or related disorders.

Intestinal Low Dose Radiotherapy Combined With Immunotherapy in Immune-resistant Metastatic Solid Tumors

Preclinical and clinical studies have shown that intestinal low dose radiotherapy (ILDR) can enhance antitumor immunity and response to immune checkpoint blockade (ICB). Therefore, the investigators launch a phase Ⅱ trial to evaluate the clinical value of combining ILDR and programmed cell death-1/ -ligand 1 (PD-1/PD-L1) inhibitors in patients with ICB refractory metastatic solid tumor. This study is designed as a researcher-initiated, two-stage and prospective clinical trial. The target population is patients with advanced metastatic malignant solid tumors who have progressed after immunotherapy. The primary endpoints include objective response rate (ORR), disease control rate (DCR), progression free survival while receiving ILDR combined therapy (PFS2), and lesion-based abscopal response rate. The secondary endpoints include incidence of adverse events (AEs), cancer-specific survival (CSS), and overall response rate (OS). Sixteen subjects will be enrolled in this trial. The primary objective is to evaluate the safety and efficacy of 1Gy ILDR combined with PD-1/PD-L1 inhibitors in immune-resistant metastatic malignant solid tumors, and biomarker exploration for response prediction. Eligible patients will be subjected to 1Gy ILDR. Tumor response will be assessed according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 as well as Immune related RECIST (iRECSIST). The extent or severity of adverse reactions will be assessed using Common Terminology Criteria for Adverse Events (CTCAE) (version 5.0). Furthermore, tissue samples, stool samples, and peripheral blood samples will be collected for biomarker exploration.

Comparison Between Virtual vs in Person on Treatment Follow-up Visits of Radiotherapy

This study aims to evaluate the logistical feasibility and implementation of virtual versus in-person on-treatment follow up visits in a high-volume radiation oncology setting. It further seeks to assess and compare patient and physician satisfaction with both modalities through structured survey data, providing insight into the clinical utility, communication quality, and overall acceptability of telehealth integration during active cancer treatment.

Low-dose Thoracic Radiotherapy Followed by Adebrelimab Plus Chemotherapy, and Then Sequential Maintenance Therapy With Adebrelimab for Extensive-stage Small Cell Lung Cancer

This study is a multicenter, prospective investigation aiming to evaluate the efficacy and safety of low-dose radiotherapy (15Gy/1.5 Gy bid × 10 fractions) combined with 4-6 cycles of systemic chemotherapy concurrently with Adebrelimab, followed by Adebrelimab maintenance therapy for up to two years, in subjects with extensive-stage small cell lung cancer (ES-SCLC). Additionally, immunohistochemical detection of the expression levels of four key transcriptional proteins-YAP1, NEUROD1, ASCL1, and POU2F3-will be performed to guide the molecular subtyping of SCLC. Based on these findings, we will explore the differential therapeutic outcomes of this regimen across distinct molecular subtypes (A/N/P/Y/I/AN/QN), with the goal of identifying the subject population most likely to benefit from this treatment modality, thereby optimizing clinical decision-making.

Anti-PCSK9 Antibody Tafolecimab and Anti-PD-1 Antibody Sintilimab Combined With Neoadjuvant Chemoradiotherapy for pMMR/ MSS Locally Advanced Rectal Cancer : A Prospective, Multicenter, Randomized, Open-Label, Parallel-Controlled Trial

This is a randomized, controlled clinical trial based on prior exploratory findings, designed to evaluate the efficacy and safety of neoadjuvant chemoradiotherapy combined with tafolecimab(an anti-PCSK9 inhibitor) and sintilimab (an anti-PD-1 inhibitor) versus neoadjuvant chemoradiotherapy combined with sintilimab alone in patients with pMMR/MSS locally advanced rectal cancer. The primary endpoint is the complete response (CR) rate, including the pathological complete response (pCR) rate in patients who undergo surgery after neoadjuvant therapy, and the clinical complete response (cCR) rate in patients managed with a watch-and-wait strategy. Secondary endpoints include major pathological response (MPR) rate, objective response rate (ORR), downstaging rate, R0 resection rate, tumor regression grade, sphincter preservation rate, disease-free survival (DFS), overall survival (OS), and safety.

A Randomized Trial of Five Fraction Partial Breast Irradiation (RAPID2)

The primary objective of this study is to determine in women with node negative BC ≤3cm in size, if PBI compared to WBI, both given once-a-day over 1 week following BCS, is non-inferior for LR and reduces adverse cosmesis. The primary outcomes are LR and patient-assessed cosmesis at 3 years post randomization.

Real-world Study on the Efficacy, Safety, and Prognostic Factors of Immune Checkpoint Inhibitors Combined With Radiotherapy in Patients With Malignant Tumors: A Prospective Non-interventional Clinical Study

Currently, chemotherapy, targeted therapy, immunotherapy, and radiotherapy are the core treatment modalities for malignant tumors, with technologies advancing rapidly. Radiotherapy can induce massive tumor cell death in a short period and expose abundant tumor-specific antigens, turning the irradiated tumor into an endogenous tumor vaccine and even causing regression or disappearance of non-irradiated tumors (the abscopal effect) . Preclinical studies have shown that stereotactic body radiotherapy (SBRT) combined with PD-1/PD-L1 inhibitors can activate systemic immunity, sensitize tumor-specific T cells to enter the bloodstream, and enable their homing to distant tumors, thereby inhibiting the growth of non-irradiated tumors . However, conclusions from rigorous randomized controlled trials have limitations when applied to the complex and heterogeneous patient populations in real-world settings. Real-world research is increasingly valued globally to complement traditional clinical trial evidence. This project prospectively collects data from patients receiving immunotherapy combined with radiotherapy in real-world clinical practice, which is of great value for evaluating long-term efficacy, safety, and impact on quality of life, and can provide high-level evidence for optimizing clinical practice and informing healthcare decisions.

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.

Hypofractionated LocoRegional Radiotherapy in Breast Cancer

The primary objective of this study is to determine if hypofractionated RT delivered over 1 week to the breast or chest wall and regional nodes (26Gy in 5 daily fractions) following BCS or mastectomy, is non-inferior to conventional fractionation to the breast or chest wall and regional nodes delivered over 3 weeks (40Gy in 15 daily fractions) in patients with node-positive breast cancer.

RIPC During Free Flap With Preoperative Radiotherapy

Remote ischemic preconditioning (RIPC) has shown organ-protective effects in many clinical settings including patients with ischemic heart disease. However its protective role in head and neck cancer patients with preoperative radiotherapy undergoing free flap reconstructive surgery has not yet been evaluated. The purpose of the current study is to evaluate the effect of RIPC on tissue oxygen saturation and skin temperature of the flap.

Neoadjuvant vs. Intraoperative vs. Adjuvant Resection Cavity Radiotherapy of Brain Metastases

Patients suffering from malignancies in advanced stages often develop brain metastases, which limit both the life span and the quality of life. Combining surgery and radiotherapy for resectable brain metastases is standard of care but there is a lot of controversy on which kind of radiotherapy is best suitable. Recently, first volumetric in-silico analyses point to theoretical advantages of neoadjuvant stereotactic radiotherapy of brain metastases. Special about this trial is the direct comparison between the three currently discussed radiotherapy options for resectable brain metastases: Neoadjuvant stereotactic radiotherapy, intraoperative radiotherapy and adjuvant stereotactic radiotherapy.

Patient Position Monitoring System for Beam Gated Radiation Therapy of Malignancies of the Chest and Upper Abdomen

This study will evaluate the feasibility of using this novel patient position monitoring system for patients receiving radiation therapy to targets involving the chest or upper abdomen, as these are the most affected by respiratory motion. This motion monitoring system will be incorporated with standard of care on-board CT imaging to confirm that the respiratory position is tracking the tumor target appropriately.

Locoregional Treatment and Palbociclib in de Novo, Treatment Naive, Stage IV ER+, HER2- Breast Cancer Patients

Approximately 3.5% to 6% of newly diagnosed breast cancer patients are stage IV metastatic. De novo metastatic breast cancer accounts for 20% to 25% of these cases. Despite a decrease in mortality in Europe and North America due to early detection and access to treatment, breast cancer remains the 2ⁿᵈ leading cause of cancer deaths in developed countries after lung cancer and the world's leading cause. In the ESME French national retrospective cohort (NCT03275311), the newly diagnosed estrogen receptor (ER)-positive and HER2-negative (luminal) metastatic patients had a 59.1 months overall survival (OS) for pre-menopausal women and 44.7 months for postmenopausal women. In the same cohort, the median OS was 47.4 months for de novo metastatic patients with hormone receptor (HR)-positive / HER2-negative breast cancer. The most important current treatment for metastatic breast cancer remains systemic therapy. Surgery and radiation are mainly used to treat symptoms. However, more than 15 retrospective studies have assessed the impact of locoregional treatment on relapse and OS. These studies suggested an improvement of the OS in patients with de novo metastatic breast cancer thanks to the addition of locoregional treatment to systemic therapy. Recent data from the ESME cohort suggest that patients with de novo luminal or HER2-positive metastatic breast cancer may benefit from local treatment of the primary tumor. Several prospective trials have attempted to demonstrate the benefit of locoregional treatment with mixed results. This can be explained by a limited power of statistical analysis, on the recruitment of patients with breast cancer of all types, and on a limited access to effective systemic therapies in some cases and all before the area of anti CD4/6 which is the current standard treatment in patients with HR-positive / HER2-negative luminal metastatic disease. However, guidelines indicate that a "multimodal approach, including curative locoregional treatments, should be considered". As a result, many clinicians offer locoregional treatment of the primary tumor, especially if there is a good response to the first line of systematic treatment. Taken together, these data underscore the need for an evaluation of the value of combined therapy - endocrine therapy - CDK4/6 inhibitor and locoregional treatment - in this population of patients with newly diagnosed HR-positive / HER2-negative breast cancer.

Effects of Moderate-intensity Interval Aerobic Exercise (MIIAE) on Inflammatory, Immune, Metabolic, Physical Fitness, and Quality of Life Parameters in Breast Cancer Patients Undergoing Radiotherapy.

Breast cancer and its treatment with radiotherapy may be associated with systemic inflammatory, hematological, cardiac, body composition, functional and quality-of-life alterations. Exercise has emerged as a non-pharmacological strategy with potential benefits during oncological treatment; however, further evidence is needed regarding the effects of supervised moderate-intensity interval aerobic exercise during radiotherapy. This randomized controlled trial aims to evaluate the effects of a supervised moderate-intensity interval aerobic exercise programme on systemic inflammatory and immune-derived hematological indices, cardiac biomarkers, body composition, muscle strength, lower-limb power, sleep quality and breast cancer-specific quality of life in women with breast cancer undergoing radiotherapy. Participants will be allocated to either an experimental group performing supervised moderate-intensity interval aerobic exercise during radiotherapy or to a control group receiving usual care without structured exercise during the study period. Outcomes will be assessed at baseline and after completion of the intervention period.

A Clinical Trial Comparing Long-Course Versus Short-Course Radiotherapy Followed by Immunotherapy Combined With Total Neoadjuvant Therapy (TNT) to Long-Course Radiotherapy Followed by TNT in Locally Advanced Rectal Cancer

This study is a national multicenter, prospective randomized, placebo- controlled Phase III clinical trial designed to investigate the potential therapeutic benefit of immunotherapy combined with total neoadjuvant therapy (TNT) and to compare the efficacy of different radiotherapy modalities followed by immunotherapy.

Timely Integration of Palliative Care in Oncology Care for Patients Referred for Palliative Radiotherapy on Bone Metastases: A Randomized Trial

Rationale: With improvements in systemic tumour-directed treatments for primary tumours, survival rates for patients with bone metastases are improving. However, individual illness trajectories become less predictable and more vulnerable to adverse events from treatments, negatively impacting a patient's quality of life (QoL). Palliative care is aimed at reducing symptoms and improving QoL for patients with incurable diseases through early identification, thorough assessment, and effective management of physical, psychological, social, and spiritual challenges. Early integration of specialist palliative care into oncology care has shown to reduce symptom burden and potentially inappropriate end-of-life care, and to enhance QoL, yet it is often initiated late. Objective: The primary objective is to evaluate the satisfaction with care and QoL experienced by patients with bone metastases who are offered a consultation with the hospital palliative care consultation team (PCCT) when referred for palliative radiotherapy compared to patients who receive standard of care. Study design: A prospective, pragmatic, two-arm multicenter randomized controlled trial within the PRospective Evaluation of interventional StudiEs on boNe meTastases (PRESENT+) cohort that follows the Trials within Cohorts (TwiCs) design. Study population: Patients with bone metastases referred for palliative radiotherapy who have their treating physician in one of the participating centers and have not been in contact with the hospital PCCT before. Intervention: A consultation with the hospital PCCT within two weeks after inclusion in PRESENT+. In the standard of care control group, no consultation with the PCCT will be scheduled. They may have a consultation during follow-up if referring physicians may consider a consultation appropriate, or when patients themselves feel they want a referral. Main study parameters/endpoints: Satisfaction with care (affective behavior) four weeks after inclusion in PRESENT+.
