Filter by:Neoadjuvant therapy is the standard diagnosis and treatment strategy for locally advanced rectal cancer defined by MRI in order to achieve tumor regression, thus affecting the selection of surgical strategy and circumferential margin, improving the safety of operation and the prognosis of patients. This study focused on the related clinical factors such as tumor regression before and after neoadjuvant therapy, combined with preoperative high-dimensional features such as radiomics, to predict the related factors of tumor regression of locally advanced rectal cancer, and validate it with multicenter. In order to develop an accurate model that can be applied to the real world and stratify the risk of locally advanced rectal cancer patients before treatment.
Aim: We evaluated the surgical outcomes of 3 groups of patients with rectal cancers - RAPIDO vs standard long course radiotherapy (LCRT) vs upfront surgery to objectively determine the effects of TNT on TME. Methods: A review of prospectively collected data was performed for patients who have rectal cancer and underwent low anterior resection from January 2016 to May 2022. Data on patient demographics, disease staging, peri-operative details and up to 2-year follow-up outcomes were analysed. The surgical and oncological outcomes were compared. Patients were followed up until 31 May 2022.
A Single-arm phase II trial evaluating induction chemotherapy with FOLFIRINOXm followed by short course radiotherapy (RT) in locally advanced rectal carcinoma
This project first retrospectively analyzes the intestinal dose indicators related to the concurrent radiotherapy and chemotherapy of rectal cancer and gastrointestinal toxicity, and the pelvic dose indicators related to hematological toxicity, and then prospectively conducts radiotherapy based on the dose indicators most closely related to toxicity. The dose is limited when the plan is made to reduce the gastrointestinal and hematological toxicity of rectal cancer with concurrent radiotherapy and chemotherapy.
The aims are to identify the trajectory of LAR Syndrome and explore the adaptation process and coping strategies of LAR Syndrome in patients newly diagnosed with rectal cancer. The participants will recruit from a CRC surgical outpatient department of a medical center in northern Taiwan.
This study proposeto integrate a variety of imaging quantitative indicators to establish a new MRI-based tumor response regression(mrTRG) classification method. The accuracy of the established mrTRG classification method according pathology TRG(pTRG) will be tested. The ability of the established mrTRG classification method to predict prognosis will also be tested.
This retrospective study aims to investigate whether initial imaging characteristics of rectal cancer on Magnetic Resonance Imaging (MRI) correlate with the underlying tumour pathology and oncological outcomes such as response to treatment. Using radiomic features, calculated using new high throughput analysis of previously acquired imaging, a statistically robust prognostic model will be created with the overall aim of developing imaging biomarkers.
People who are diagnosed with cancer of the colon/rectum/appendix/ovaries that spreads into the lining of the tummy and some ovarian cancers or people with pseudomyxoma peritonei can often undergo intensive treatment including major surgery where chemotherapy is given whilst the person is having surgery - also known by doctors as surgery and hyperthermic intraperitoneal chemotherapy (HIPEC). Fitness for this surgery can improve if people undertake a prehabilitation programme at the time they get their diagnosis. To date, little research has focused on how exercise and nutrition support before surgery can help these patients during recovery. The aim of this study is to explore the use of exercise and nutritional support pre-treatment to enhance physical and psychological outcomes for patients.
The aim of the ShorTrip trail is to evaluate the activity and the safety of total neoadjuvant strategy with FOLFOXIRI as consolidation therapy preceded by short-course radiotherapy and followed by surgery in LARC patients.
Short-course radiotherapy combined with immunotherapy may bring revolutionary changes to the preoperative neoadjuvant treatment mode for locally advanced rectal cancer. According to the existing theory, the use of PD-L1 monoclonal antibody after short-course radiotherapy may be the best solution. In this study, the investigators will perform single-cell sequencing of participants tissue samples, fully explore the multi-dimensional omics information of tumors and microenvironments, explore the characteristics of the treatment benefit population, and try to construct an efficacy prediction model to screen the treatment benefit population early and implement precise treatment.
