Filter by:Routine clinical and radiological assessment of response of patients with rectum cancer to neoadjuvant chemoradiotherapy does not allow accurate identification of complete pathological response, and leads to frequent false positive and negative results. Molecular markers reflecting the initial and post-nCRT status of the tumor would be ideal to select patients eligible for organ preservation. This project will test the detection of tumor extracellular vesicles (EVs) in liquid biopsy as a reliable marker for the identification of poor versus good responders to nCRT.
To investigate the oncological outcome of lateral lymph node dissection in low rectal cancer based on MRI
The equilibrium of intestinal microorganisms is essential for health an imbalance has been associated with an increased risk in the development of different pathologies; including colorectal cancer. Rectal cancer is the third most common neoplasm worldwide and the complete excision of the mesorectum is a major prognostic factor. The identification of microorganisms in the adipose tissue that surrounds the small intestine in inflammatory diseases, together with bacterial alterations found in colonic mucosa and feces in patients with rectal cancer in comparison with healthy individuals indicates that microbiome alteration plays an essential role in pathogenesis. The mesorectal microbiome in rectal cancer patients stills unknown and given its importance in the prognostic of the disease the goal of this study is to identify microbial profiles that allow predicting rectal cancer patients with a poor prognosis.
The purpose of this study is to evaluate the safety and efficacy of preoperative chemoradiotherapy (IMRT) with concurrent high-dose intravenous vitamin C and mFOLFOX6 in locally advanced rectal cancer patients.
Major abdominal oncology surgery is associated with substantial postoperative loss of functional capacity, and exercise may be an effective intervention to improve outcomes. The aim of this study was to assess efficacy, feasibility and safety of a supervised postoperative exercise programme in patients undergoing immediate internal pudendal artery perforator flap reconstruction for irradiated abdominoperineal resection defects. We will perform a open label, parallel-arm, randomized trial in patients who underwent immediate internal pudendal artery perforator flap reconstruction for irradiated abdominoperineal resection defects in a tertiary university hospital. Patients will be randomized to an early mobilization postoperative programme based on supervised aerobic exercise, resistance and flexibility training or to standard rehabilitation care - bed restriction for 5 days. The primary outcome will be inability to walk without human assistance at postoperative day 5 or hospital discharge.The secondary outcomes will be incidence of surgical complications, ability of walk assessed for the 6-minute walk test, incidence and intensity of fatigue measured by Piper's Revised Fatigue Scale, improvement of quality of life measured by EuroQuol-5D-5L Questionnaire, Incidence of deep venous thrombosis.
DESIGN: Randomized, open-label and parallel clinical trial, assigned to early, mid, or late withdrawal of urinary catheter with a 1: 1: 1 allocation ratio. POPULATION: Patients undergoing anterior rectal resection, low rectal resection, or abdominoperineal amputation for any reason. OBJECTIVES: The main objective is to compare the incidence of acute urine retention after removal of the urinary catheter in the postoperative period of rectal resection. Secondary objectives are: 1. Incidence of urinary tract infection after urinary catheter removal. 2. Incidence of specific postoperative complications (Surgical wound infection, Respiratory infection, Anastomotic dehiscence, ileus). 3. Incidence of postoperative complications assessed according to the Comprehensive Complication Index (CCI) scale. DESCRIPTION OF THE INTERVENTION: In all patients, a Rectal Resection (anterior rectal resection, posterior pelvic exenteration or abdominoperineal amputation) will be performed. In group 1A, the urinary catheter will be removed on the 1st postoperative day. In group 1B patients, the urinary catheter will be removed on the 3rd postoperative day. In group 1C patients, the urinary catheter will be removed on the 5th postoperative day. All patients will have a urine culture taken at the time of withdrawal.
This study is to investigate the role of traditional Chinese medicine (TCM) on the postoperative recovery of rectal cancer patients.
This is a randomized, controlled, parallel study to determine the efficiency and safety of total neoadjuvant therapy in rectal cancer treatment.
Background There is currently no reliable means to restage rectal cancers after neoadjuvant chemoradiation. There are still no reliable methods to identify patients with pCR before radical surgery. As a result, clinical complete response (cCR), defined as no clinical detectable tumor by physical examination, endoscopic evaluation, and imaging, is designed as a surrogate endpoint for pCR. However, the concordance between cCR and pCR varies from 22% to 96% in different reports, which questions the clinical value of such strategies. Therefore, based on rectal diginal examination, serum CEA, MRI, endoscopy examination, we suggested to add multi-points and full-thickness biopsy technique to further improve the accuracy of cCR.
This study is a single-center, open, prospective, single-treatment trial (pilot study). This study aims to analyze the treatment results after receiving capecitabine adjuvant chemotherapy for 4 months after non-surgical treatment in patients who had completed and could have clinical complete remission with capecitabine preoperative chemoradiotherapy with capecitabine for mid-to-lower rectal cancer and to investigate the feasibility of non-surgical treatment.
