Rectal cancer presents a significant global health challenge. Despite improvements in clinical outcomes, significant disparities persist across Europe. These differences are explained not only by the heterogeneity of risk factors and screening strategies, but also by variations in diagnostic and therapeutic approaches, which are highly dependent on medical imaging. Standard treatment for locally advanced rectal cancer based on staging MRI is neoadjuvant treatment (NAT), for tumour downsizing and downstaging, followed by total mesorectal excision. In a significant proportion of cases, radical surgery leads to substantial long-term complications like sexual and urinary dysfunction, fecal incontinence, and impairment in daily activities. Given that up to 42% of patients show complete tumor regression at pathology (i.e. pathological complete response pCR), to avoid unnecessary radical surgery, non-operative management has become an attractive alternative when there are no signs of viable tumour after NAT (i.e. clinical complete response cCR). Such patients are candidates for Watch-and-Wait (W\&W), an established active surveillance policy in specialized centers worldwide relying on clinical examination, endoscopy and MRI. On the other hand, W\&W carries a risk of local regrowth (persistence of microscopic residual disease despite apparent cCR). Even in expert hands, assessment of tumor response is not perfect and local regrowth based on current selection methods occurs in \~30% of cases. Although deferred surgery is a successful treatment with no apparent negative impact on local disease control, an increased rate of distant metastases has been recently reported. Therefore, there is a critical unmet clinical need to detect complete responses after NAT and avoid unnecessary surgery with its associated morbidity and quality of life impairment risks, while also improving sensitivity for residual microscopic disease that will result in local regrowth and associated reduced disease-free survival. Rectal cancer poses a burden not only on healthcare systems, but also on patient well-being. Patients frequently suffer from feelings of isolation and helplessness when faced with unpredicted disease-related situations, given the common difficulties to access high quality information and communicate with attending physicians. As such, there is a clear need to unburden healthcare facilities from unnecessary hospital visits, while improving patient outcomes, engagement, support and care.

This randomized phase II exploratory clinical study aims to evaluate the efficacy and safety of SHR-1701 in patients with unresectable stage III non-small cell lung cancer (NSCLC). A total of 84 eligible patients will be randomized 1:1 into an induction immunotherapy group or a consolidation immunotherapy group. Group A will receive SHR-1701 combined with platinum-based chemotherapy as induction therapy followed by concurrent chemoradiotherapy (cCRT) and subsequent SHR-1701 consolidation therapy, while Group B will receive standard cCRT followed by SHR-1701 consolidation therapy. The primary endpoint is progression-free survival (PFS). Secondary endpoints include objective response rate (ORR), disease control rate (DCR), overall survival (OS), and safety outcomes.

This multicenter, prospective cohort study investigates the long-term impact of nutritional status on clinical outcomes in cancer patients undergoing treatment in Shaanxi Province, China. It evaluates how malnutrition, dietary patterns, and nutritional interventions affect treatment tolerance, quality of life, and survival. The study tracks dynamic changes in nutritional health and related indicators throughout various stages of chemoradiotherapy, aiming to inform evidence-based strategies for precision nutrition in oncology care.

This study hypothesizes that approximately 50% of rectal cancer patients can preserve their rectum using a watch-and-wait strategy if they achieve a complete or near-complete clinical response to total neoadjuvant therapy (TNT). The objective is to determine whether the complications, quality of life, and survival rates of rectal cancer patients who have achieved a complete or near-complete clinical response to TNT, followed by a watch-and-wait approach, are comparable to those of patients who undergo surgery first. Additionally, the study aims to identify potential prognostic and predictive markers for rectal cancer and examine survival rates and factors influencing responses to chemoradiotherapy (CRT) or TNT. The study is divided into two parts: \*\*Part One:\*\* Participants with cT1N1, T2-T3 N0-1 rectal cancer, MRF-, and EMVI-, with surgery as one of the possible first-line treatment options, will be randomized into two groups. The experimental group will consist of participants receiving TNT, including CRT and consolidation chemotherapy (Ch). If these participants achieve a complete or near-complete clinical response, they will be observed using a watch-and-wait strategy, which is a non-operative approach. The control group will consist of participants who undergo surgical treatment initially. \*\*Part Two:\*\* All participants with rectal cancer who have received CRT or TNT will be included. Additionally, participants diagnosed with rectal cancer who are scheduled for CRT or TNT but declined to participate in Part One or do not meet the inclusion criteria will also be included.

Definitive chemoradiotherapy (CRT) is the standard treatment for locally advanced unresectable esophageal cancer, but its efficacy remains unsatisfactory. More importantly, there is a lack of effective consolidation treatment after CRT, resulting in a high recurrence rate. Our previous prospective phase II trial (EC-CRT-001) demonstrated that the addition of toripalimab to definitive CRT improved the complete response rate in patients with locally advanced esophageal squamous cell carcinoma (ESCC), showing potential for enhanced long-term survival with a manageable safety profile. Nevertheless, the risk of recurrence requires further reduction. Metronomic capecitabine chemotherapy can modulate the tumor immune microenvironment and may synergize with PD-1 antibodies to enhance antitumor efficacy, potentially further prolonging survival in ESCC. Based on current research advances and our preliminary findings, this randomized, controlled, multicenter, phase III clinical trial aims to evaluate the efficacy and safety of toripalimab combined with capecitabine as maintenance therapy for patients with locally advanced ESCC who have not progressed after definitive CRT.

Based on the preclinical rationale for combining surufatinib with immunotherapy, and the clinical efficacy observed with surufatinib in extensive-stage small cell lung cancer (ES-SCLC), the investigators hypothesize that incorporating surufatinib into the ADRIATIC regimen could further enhance survival in LS-SCLC. To evaluate this approach, the investigators plan to conduct a single-arm Phase II study to explore the safety and efficacy of concurrent chemoradiotherapy combined with toripalimab and surufatinib in treating LS-SCLC.

This is a combination of retrospective and prospective observational study that will be performed across NCG and other participating centers to report compliance to chemoradiation for cervical cancer. This audit will include patients treated with standard of care treatment, in this case definitive or adjuvant radiation+/- concurrent chemotherapy will be included. Patients recruited in various institutions in prospective clinical trials will not be included. The participating centersthat agree to contribute data will include all registered cases over a 6-month period that have been diagnosed with cervical cancer wherein treatment is planned with radical dose radiation and/or concurrent chemotherapy. Centers that do not have retrospective data of the patients will contribute data of patients registered prospectively over 6 months. Furthermore, any cases referred to the institution for brachytherapy alone will also be included. As a first step member institutions that participated in guideline development process or provide an agreement to guidelines adherence will be audited. The project will be submitted in institutional ethics committees with memorandum of understanding for anonymized data sharing. Each of the co-investigators listed from contributing centers will be directly responsible for collecting data contribution and accuracy of data submitted. Those centres which cannot or do not want to participate will be requested to provide data on only compliance outcomes to treatment for at least of 5 consecutively patients diagnosed with cervical cancer wherein treatment is planned with radical dose radiation and /or concurrent chemotherapy over a period of 6 months.

This is a prospective observational study designed to observe and evaluate the safety and efficacy of mecapegfilgrastim in the treatment of moderate-to-severe myelosuppression associated with concurrent chemoradiotherapy. The project will provide more robust evidence-based medical support for the use of long-acting granulocyte-stimulating agents in patients undergoing concurrent chemoradiotherapy.

The PACIFIC study established the standard of care for immunotherapy consolidation after chemoradiotherapy (CRT) in patients with unresectable stage III non-small cell lung cancer (NSCLC). However, its benefit is limited in patients with driver gene mutations. The LAURA study established a new paradigm of targeted consolidation therapy after CRT for patients with EGFR mutations. Although retrospective data support the efficacy of ALK-TKIs, no randomized controlled trial (RCT) has clearly demonstrated the value of ALK-TKI maintenance therapy after CRT. This study adopts a multicenter, randomized, double-blind, placebo-controlled design aimed at evaluating the efficacy and safety of ensartinib in patients with ALK-positive unresectable stage III NSCLC.

The combination of surufatinib with neoadjuvant chemo-immunotherapy and definitive concurrent chemoradiotherapy represents a promising new therapeutic strategy that may further improve the prognosis of patients with unresectable locally advanced esophageal squamous cell carcinoma (ESCC). Therefore, we propose to conduct a prospective, single-arm, phase II clinical trial to evaluate the efficacy and safety of this regimen in patients with unresectable, locally advanced ESCC.

This study aims to evaluate the efficacy and safety of short-course radiotherapy combined with CAPOX plus bevacizumab with or without a PD-1 inhibitor in patients with locally advanced rectal cancer (LARC). The hypothesis is that the addition of immunotherapy (PD-1 inhibitor) can significantly improve the complete response (CR) rate and enhance local control while reducing the incidence of distant metastasis. This study will compare the effects of sequential chemoradiotherapy and targeted therapy with or without immunotherapy following short-course radiotherapy, aiming to explore the optimal regimen for total neoadjuvant therapy.

This prospective observational study aims to evaluate symptom burden and symptom clusters among lung cancer patients undergoing definitive concurrent chemoradiotherapy (CRT), based on electronic patient-reported outcomes (ePROs). Patients will complete the validated MDASI-LC and EQ-5D instruments weekly from baseline through the end of CRT and for 12 weeks post-treatment. The study will characterize the longitudinal trajectories of symptom severity and interference, identify distinct symptom clusters and their temporal patterns, and explore patient-level predictors of symptom burden. The findings may support the development of personalized symptom management strategies and improve quality of life during and after CRT.

Although unprecedented advances have been made in the field of esophageal cancer in recent decades, the prognosis for patients with locally advanced esophageal squamous cell carcinoma (ESCC) remains extremely poor, accounting for 30-40% of overall survival at 5 year. In recent years, multimodal treatments have proven to be an appropriate therapeutic approach for locally advanced ESCC. Recently, immunotherapy developed rapidly. The purpose of this study was to observe the efficacy and safety of cardonilizumab combined with chemoradiotherapy in the treatment of locally advanced ESCC.

This study aims to evaluate the impact of an intelligent care system on radiation therapy patients, focusing on real-time blood data monitoring, optimized patient education, and internal alert systems. The goal is to enhance patient safety, improve treatment adherence, and reduce anxiety by integrating an alert function into the hospital's existing system. Key interventions include: Real-time blood monitoring alerts: Healthcare providers will receive automatic notifications of abnormal blood test results to ensure timely intervention. Optimized patient education materials: Clearer guidance will help patients proactively communicate blood test needs and manage their health during radiation therapy. Internal reminders: Visual signs and alerts in treatment areas will reinforce patient awareness and engagement. The study will compare patients receiving these interventions with those under standard care, assessing treatment compliance, anxiety levels, and clinical outcomes over a 12-month period.

This phase I/II clinical study is designed to evaluate the 1 year local tumor control rate of chemoradiotherapy using albumin-bound paclitaxel and cisplatin in unresectable esophageal squamous cell carcinomas based on Nutritional Risk Screening NRS2002.

To evaluate the efficacy and toxicity of sodium glycididazole combined with concurrent chemoradiotherapy in patients with unresectable locally advanced non-small cell lung cancer after neoadjuvant chemoradiotherapy.

This trial is a prospective, randomized, controlled, multicenter, phase II clinical study to evaluate the efficacy and safety of sintilimab as consolidation therapy in elderly patients with esophageal cancer who did not progress after concurrent chemoradiotherapy. Patients aged 70-85 years with esophageal squamous cell carcinoma who did not progress after concurrent chemoradiotherapy and meet the inclusion criteria will be stratified according to MRD status (positive vs negative) and randomized in a 1:1 ratio into two groups: the treatment group receiving sintilimab (for patients with a weight \<60 kg: 3 mg/kg IV on Day 1 every 3 weeks; for patients with a weight ≥60 kg: 200 mg IV on Day 1 every 3 weeks) and the observation group receiving regular follow-up. Patients should receive the first dose within 42 days after completing the last radiotherapy session and continue treatment until disease progression, intolerable toxicity, loss to follow-up, death, or other circumstances where the investigator determines treatment should be discontinued, whichever occurs first. The maximum duration of sintilimab treatment is 12 months (from the start of treatment), while the observation group will be followed up every 3 months for at least one year. No other anti-tumor treatments are allowed during the study period. The study aims to compare the effects of the two treatment modalities on progression-free survival, overall survival, tumor response, toxicity reactions, and quality of life in elderly patients with esophageal cancer.

Elderly or malnourished patients diagnosed with locally advanced esophageal squamous cell carcinoma (ESCC) had poor prognosis. Radiotherpy was an important and effective treatment in treating ESCC. The present study is a one-arm trial that seeks to evaluate the efficacy in patients with unresectable ESCC. The study objectives include R0 resection rate, complete pathological response and treatment toxicity, etc. Nimotuzumab is a recombinant humanized monoclonal antibody against EGFR. Its efficacy and safety in patients with esophageal cancer have been confirmed by many studies. The current prospective phase II study aimed to evaluate the efficacy and safety of a combination regimen comprising chemotherapy with nimotuzumab with a dose of 800mg per week and S-1 and concurrent radiotherapy for patients who are elderly or malnourished.

The current prospective phase II study aimed to evaluate the efficacy and safety of a combination regimen comprising chemotherapy with nimotuzumab and S-1 and concurrent radiotherapy for patients who are not sensitive to induction chemo(immuno)therapy.

Cervical cancer constitutes a significant health burden for women globally. While most patients with early-stage disease can be cured with radical surgery or chemoradiotherapy, patients with high-risk locally advanced disease or with recurrent/metastatic disease have a poor prognosis with standard treatments. Immunotherapies are a rational treatment for this HPV-driven cancer that commonly expresses programmed cell death ligand-1. Toripalimab, a humanized immunoglobulin G4 monoclonal antibody against PD-1, showed promising anti-tumor efficacy in multiple solid tumors. This randomised study is evaluating toripalimab combined with CCRT versus CCRT alone for treatment-naïve LACC.

Esophageal cancer accounts for more than half of the world, seriously affecting people's health in China. 95% patients are squamous cell carcinoma. Surgery is the preferred treatment for early and middle stage esophageal cancer, but patients with clinical stage T4b or other surgical contraindications have no surgical opportunity. In recent years, radical chemoradiotherapy has played a key role in the treatment of local advanced esophageal cancer with some poor predicting biomarkers. Oral bacteria may play a pathogenic role in cancer and other chronic diseases by producing chemical carcinogens and inflammatory factors through direct metabolism. A large number of studies have also suggested that tooth loss and poor oral hygiene are closely related to upper digestive tract cancer, indicating the possible role of oral microorganisms in the occurrence and development of upper digestive tract cancer, and saliva is the main source of oral flora colonization. Therefore, it is worth further research to explore the interaction between microbial metabolism imbalance and radiotherapy in patients with esophageal cancer. In summary, we intend to conduct a prospective cohort study to explore the role of salivary microbes in radiotherapy in patients with initially inoperable patients with local advanced esophageal cancer.

Chemoradiotherapy has been a standard modality for inoperable locally advance esophageal carcinoma. The goal of this randomized control study is to compare the feasibility, and survival benefits of whole-course immunonutrition combined with chemoradiotherapy±ICIs for local advanced patients with inoperable esophageal squamous cell carcinoma. The main questions it aims to answer are: • If the feasibility and safety of whole-course immunonutrition combined with chemoradiotherapy±ICIs is better. • If the survival benefits (1, 2 and 3-years progression free survival) of whole-course immunonutrition combined with chemoradiotherapy±ICIs is longer. The Experimental group will receive a combination immunonutrition of omega-3 fatty acids, and glutamine, whereas the control group will receive standard formula.

This study carried out a prospective, randomized, controlled clinical study under the background of intensity-modulated radiation therapy and three-dimensional afterloading therapy. By comparing simultaneous intensity-modulated radiotherapy and chemotherapy combined with adjuvant chemotherapy and simultaneous intensity-modulated radiotherapy and chemotherapy alone, based on the 2018 FIGO staging The clinical efficacy of locally advanced cervical cancer further clarifies the role of adjuvant chemotherapy in locally advanced cervical cancer.

In left-sided colon and rectal cancer, the occurrence of synchronous para-aortic lymph node metastasis is rare, with the incidence of being approximate 1-2%. Currently, there has been no standard treatment strategy for this situation. The present trial is designed to evaluate the safety and efficacy of para-aortic lymph node dissection for left-sided colon and rectal cancer with synchronous para-aortic lymph node metastasis
