Filter by:This study is to evaluate the disease control rate and time to progression of the sequential combination of oxaliplatin with an alternative anti-metabolite Trifluridine/tipiracil hydrochloride mixture, TAS-102,(TAS-OX) as well as irinotecan in combination with TAS-102 oxaliplatin(TAS-OX) + Bevacizumab in late-line metastatic colorectal cancer (mCRC)
The goal of this prospective phase II feasibility study is to evaluate two additional local treatment options in rectal cancer patients with a good clinical response after neoadjuvant (chemo)radiation: contact x-ray brachytherapy versus extension of the waiting interval with or without local excision, and to investigate which rate of organ preservation can be achieved.
With 50 patients included, this trial would be the largest pilot study evaluating the value of MRI PET in locally advanced rectal cancer. On the other hand, it would be the only pilot study performing several MRI PET during neoadjuvant treatment. Presumably, the response assessed at the 2nd MRI PET (before cycle 4 or induction chemotherapy) would be predictive of the overall response at the end of neoadjuvant treatment. Then, it would be possible to predict precociously the tumor response.
The purpose of this study is to investigate the efficacy and safety of combined fruquintinib、toripalimab and SRT in neoadjuvant therapy for locally advanced rectal cancer.
This study focused on the alterations of gut microbiome and function during defunctioning ileostomy, and observed the effects of probiotic intervention on intestinal microbiome and function. The investigators looked forward to find the specific intestinal maladjusted flora from this work, which could provide a new scheme for the subsequent treatment of the damaged intestinal function and the reduction of the incidence of postoperative complication.
Short-course radiotherapy combined with immunotherapy may bring revolutionary changes to the preoperative neoadjuvant treatment mode for locally advanced rectal cancer.In view of the shortcomings of the current preoperative neoadjuvant treatment model for locally advanced rectal cancer, we will explore the feasibility of a new model of short-course radiotherapy combined with immunotherapy, and develop a possible optimal plan based on the existing theoretical basis, namely "short-course radiotherapy + PD-L1 monoclonal antibody combined with CAPEOX chemotherapy for 2 cycles", and explore the efficacy and adverse effects of this model. The study will also attempt to explore the characteristics of the treatment beneficiary population, explore the characteristics of the treatment beneficiary population by multi-dimensional tumor and microenvironmental information through multi-omics sequencing analysis, attempt to build an efficacy prediction model, early screening of the treatment beneficiary population for precise treatment, and thus explore a new model of radiotherapy combined with immunotherapy.
Retrospective and prospective observational study of patients undergoing advanced pelvic oncological resection for maligancy including multi visceral resection, beyond TME resection and sacrectomy/flap reconstruction/urinary reconstruction at Glasgow Royal Infirmary. Goal is to study and report outcomes for patients to characterise and understand major complications, natural history of resectional patients and identify areas for future interventional study.
The treatment protocol proposed in this study is to perform short-term radiation therapy and 4 cycles of FOLFOX chemotherapy for neoadjuvant treatment of locally advanced rectal cancer. Compared to conventional chemoradiation therapy, the preoperative radiotherapy period is shortened, and the cure rate of rectal cancer patients can be improved by early treatment of micrometastasis using systemic chemotherapy. The patients who are assigned to the study group will received the short-course radiotherapy and 4 cycles of FOLFOX and patients in the control will received conventional chemoradiotherapy for preoperative treatment. All patients are recommended to receive total mesorectal excision (TME) after neoadjuvant treatment and adjuvant chemotherapy will be given according to the pathological stage.
The study researchers believe that a combination of the drugs trastuzumab and tucatinib, given with standard chemotherapy (capecitabine and oxaliplatin/FOLFOX), may help participants with rectal cancer.
Anastomotic complications are serious complications after anus preserving surgery for rectal cancer,the instrument anastomosis technology are one of the factors that influence the occurrence of anastomotic complications after surgery,the laparoscopic linear cutting closure device used in robotic rectal cancer may increase the occurrence of anastomotic complications,but the robot linear cutting stapler (SureForm) may reduce the incidence of postoperative anastomotic complications due to the technical advantages,therefore,the aim of this study is to evaluate the impact of robotic linear cutting stapler SureForm and laparoscopic linear cutting stapler on the incidence of anastomotic complications after robotic rectal cancer anus preserving surgery.
