Filter by:This study is a single-arm, open-label, dose-escalating + dose-expansion clinical study, aiming to evaluate the safety and efficacy of CEA-targeted CAR-T cell preparations, and to preliminarily observe the study drug in CEA-positive advanced malignant tumors. The pharmacokinetic characteristics of CAR-T cell preparations for the treatment of patients with CEA-positive advanced malignancies were obtained and the recommended dose and infusion schedule.
The purposes of this study are to explore the trajectory of symptom distress and balance ability in patients with rectal cancer.
This study is a prospective monocentric study aimed to explore the value of 68Ga-FAPI-04 PET imaging in early response evaluation of rectal cancer patients treated with immunotherapy. Patients with histopathologically confirmed diagnosis of rectal cancer will be recruited and undergo 68Ga-FAPI-04 and 18F-FDG PET imaging before treatment and after short-course radiotherapy and two cycles of neoadjuvant chemotherapy plus immunotherapy. The two imaging intervals will be completed two days apart. The efficacy of 68Ga-FAPI-04 in early response evaluation will be compared with the general imaging agent 18F-FDG. The general information, clinical data, mpMRI data, 68Ga-FAPI-04 and 18F-FDG PET imaging results and other imaging data of the patients will be collected. The histopathology of the biopsy or surgical specimen after 2 cycles of therapy and follow-up data will be taken as evaluation references. This study plans to set the sample size as 20 cases
This study aimed at comparing the Comprehensive Complication Index (CCI), readmission rates, postoperative hospitalization days, duration of bearing the stoma (months), hospitalization costs, the number of hospitalizations with ghost ileostomy versus conventional loop ileostomy after low anterior resection for rectal cancer.
Comparative analysis of the clinical efficacy between primary Total Mesorectal Excision (TME) surgery and neoadjuvant chemotherapy combined with TME surgery for low-risk locally advanced rectal cancer. Randomly enrolling eligible patients into either the control group receiving neoadjuvant chemotherapy combined with TME surgery or the experimental group receiving primary TME surgery, and subsequently comparing the clinical outcomes of the two groups
In the present project, the investigators plan to more accurately select the rectal cancer patients with pathological complete response (pCR) to preoperative concomitant chemoradiation therapy (CCRT), taking advantage of quantification of circulating tumor DNA (ctDNA) in addition to the current available diagnostic modalities, including CT, MRI, PET and colonoscopy. The patients with suspected pCR to CCRT will be randomized to radical surgery and local excision groups, followed by the comparison of the oncologic outcomes between two treatment methods. The investigators hypothesized that if the pCR for patients with rectal cancer after CCRT can be more accurately predicted, such patients can be safely treated with limited surgery to enhance the post-treatment life quality, in comparison with patients undergoing radical surgery.
To increase the efficacy of neoadjuvant PD-1/PD-1 checkpoint inhibitor in local advanced rectal cancer (LARC), we propose preoperative arterial infusion of Tirellizumab and oxaliplatin followed by tumor artery embolization with concurrent chemoradiotherapy as neoadjuvant regimen for LARC.
This trial (molecular characterization trial) focuses on rectal cancer, a common cancer that is treated with radiotherapy (RT) as standard of care and represents a setting in which to study the effects of RT on the immune system.
Prospective, open label, multi-dose, sequential dose escalation, single-center, Phase 1 trial
The goal of this clinical trial is to compare the efficacy of using polypropylene mesh for hernia prevention after stoma closure in patients with colorectal cancer and non-mesh repair. The main question it aims to answer is: can mesh help prevent hernia? Participants will be divided into 2 groups: with and without mesh using. They must be followed up for 2 years after enrollment in the study. Researchers will compare mesh and non-mesh groups to evaluate the benefits and harms of mesh using in hernia prevention.
