Filter by:Colorectal cancer ranks the second lethal cancer and third prevalent malignant tumour worldwide, Despite of different odern modalities for diagnosis,large number of cases diagnosed at metastatic advanced stage . New treatment approach has been discovered habe been discovered making a huge revolution in metastatic colorectal cancer represented by targeted therapy including anti_EGFR ,anti_angiogenic and kinase inhibitors .
The aim of this retrospective cohort-study is to assess the effects of AL and its severity divided according the ISREC-classification on the long-term oncological outcome.
Quality of life and risk factors for developing major LARS are explored. Therapeutic options were explored in the cohort experiencing major LARS
The Intersphincteric resection (ISR) technique is an alternative for anal preservation in ultra-low rectal cancer. The transanal total mesorectal excision (TaTME) technique might compensate for the deficiencies of ISR in terms of tumor spillage and poor surgical field exposure. Thus, the investigators perform ISR through a transanal endoscopic approach (taE-ISR), seeking to evaluate the value of this innovative technique in anal preservation in ultra-low rectal cancer.
Colorectal cancer is the third leading cause of cancer death and the fourth most commonly diagnosed cancer in the world. The importance of improving the quality of life of patients after colorectal cancer surgery has been gradually emphasized as the survival period after treatment increases. Especially, patients who underwent rectal cancer surgery experience complex bowel movement abnormalities called 'lower anterior resection syndrome' such as urgency, tenesmus, frequent stool passing, which severely degrades the quality of life after surgery. To manage these symptoms, several treatment modalities including medication, neurostimulation, or biofeedback have been tried, but they are not fully effective. Therefore, we designed this clinical trial to examine the effects of dietary supplementation of the fruit, 'Prune', on improving bowel function after anterior resection rectal cancer surgery. Prune is a dried fruit made from American plums with no seeds, and popular in the worldwide for its sweet and sour flavor and texture. In particular, the high content of sorbitol and dietary fiber softens the stool and improves the overall intestinal function, showing an excellent effect on alleviating constipation symptoms, which has been well studied in several clinical trials. This study is going to be performed on patients under the age of 65 with primary rectal cancer and rectosigmoid colon cancer who underwent low anterior resection (LAR) exclusive of neoadjuvant chemoradiotherapy. Patients who are treated preoperatively with metallic stent insertion will be excluded. Those who have fruit allergy, diabetes, or chronic constipation will also be excluded. Subjects will be randomly assigned to treatment (Prune) or control group (No-prune) immediately after the surgery. Subjects who are assigned to the treatment group consume a total of 100 g of prune per day and the subjects assigned to the control group are allowed to have a normal meal without prune for 18 days. All subjects should fulfill the LAR syndrome questionnaire, The European Organization for Research and Treatment of Cancer quality of life questionnaire (EORTC QLQ-c30), and the defecation habit questionnaire on the day before the surgery and the postoperative day 21. And the subjects also fulfill the defecation diary till the postoperative day 21. The primary endpoint is the incidence of LAR syndrome. The secondary endpoint was the score of EORTC QLQ-C30, defecation habit questionnaire. Prune intake is less costly than conventional medical treatments for improving bowel function, and it is expected to show high compliance for patients due to the ease of application. Furthermore, if this study demonstrates that prune intake improves the symptoms of LAR syndrome and quality of life after rectal cancer surgery, the ingredients and components of prune could be used to develop new drugs for alleviating the symptoms of LAR syndrome.
Introduction: In locally advanced rectal cancers (LARC), TNM staging is far from optimal. We aimed to investigate the value of previously described circulating biomarkers as predictors of prognosis. Methods: Retrospective analysis of 245 LARC patients diagnosed between January 2010 and December 2022, who underwent neoadjuvant chemoradiotherapy and surgery at two centers. A Cox regression and Kaplan-Meier analysis were performed.
Compared with traditional manual suturing, mechanical anastomosis can reduce the error caused by human factors. The electric anastomotic device can improve the automation and accuracy of anastomosis, reduce the requirements for doctors' operation, and establish a more standardized usage specification, thereby reducing the surgical complication rate and improving the quality of anastomosis. The clinical study of electric tubular anastomotic device adopts a multicenter, randomized, parallel controlled non-inferior study design, and randomly groups according to the 1:1 ratio to evaluate the clinical effectiveness and safety of electric tubular anastomotic device compared with conventional manual device.
This study investigates the potential benefit of re-irradiation of patients with locally advanced rectal recurrences, by a prospective phase II clinical, imaging and translational research study.
Ramucirumab is a biosimilar drug of CYRAMZA® produced by Chiatai Tianqing Pharmaceutical Group Nanjing Shunxin Pharmaceutical Co., LTD. It is a vascular endothelial growth factor receptor 2 (VEGFR-2) antagonist. This single-center, randomized, double-blind, single-dose, parallel phase I study of Ramucirumab injection versus Cyramza ® in healthy male volunteers was designed to evaluate the similarities in pharmacokinetics, tolerance, safety and immunogenicity of Ramucirumab and CYRAMZA®.
Investigator retrospective collect cases during 2010-2021 diagnosed as rectal adenocarcinoma with high quality CT images. Local advanced rectal cancer cases were labeled as "disease". Nor were defined " normal". Using artificial intelligence CNN on jupyter notebook with open phyton code to train and develop models capable to recognizing local advanced rectal cancer. Modify the phyton code for better predict rate and help physician to quickly evaluate disease severity for fresh rectal cancer cases.
