Filter by:This phase II trial is assessing how 64Cu-ATSM (64Cu-copper(II) diacetylbis(N4-methylthiosemicarbazone)) PET/CT scan could predict neo adjuvant treatment response in rectum cancer locally advanced
The problem of anastomotic leak is particularly relevant in rectal surgery. Many risk factors have been recognized in the onset of this complication. Preventing the anastomotic leak can bring benefits to the patient and the health system. Several attempts have been proposed to reduce the risk of anastomotic leakage in rectal cancer surgery including suture protection with omental flap and external suture reinforcement by biological glue or mesh. Cyanoacrylate (Glubran 2®) is a synthetic glue with sealing, adhesive and hemostatic properties widely used in surgery. The sealing effect creates an antiseptic barrier against bacteria. The hypothesis is that the application of nebulized cyanoacrylate to the colo-rectal anastomosis in open or laparoscopic/robotic rectal surgery can prevent the leakage
The current standard of care for rectal cancer has diminished local recurrence and enhanced survival. Quality of life, however, remains poor for many patients and the probability of distant recurrence is high. In this study, we will attempt to reduce the distant recurrence rate and improve quality of life by making changes in the timing and administration of chemotherapy and radiation and doing less invasive rectal surgery when indicated.
Colorectal cancer is a common malignancy in Viet Nam. Laparoscopic surgery becomes a standard treatment in many centers. Today, robotic surgery is a new option for treating colorectal cancer with some advantages such as magnified 3D view, precise movements. Answer on safety and feasibility of robotic surgery for colorectal cancer are not available in Viet Nam. Therefore, the investigators conducted a study " Robotic versus Laparoscopic Approach for Rectal Cancer Surgery".
Though refusal of radical surgery was often happened in rectal cancer patient after neoadjuvant chemoradiotherapy, little is currently known about the actual oncologic outcome of it. Thus the investigators designed this study to compare the oncologic outcome of unintended rectal preservation with intended rectal preservation by surgeon.
This is a phase II, prospective, open label, one-center study for evaluation of the addition of nivolumab to the chemotherapy phase of the neoadjuvant treatment for locally advanced rectal cancer patients. Subjects must have received no prior treatment for rectal cancer (chemotherapy, radiotherapy or surgery) and no prior treatment with checkpoint inhibitors. Eligible subjects will receive chemoradiation for a period of 5 weeks, 6 cycles of chemo-immunotherapy (mFOLFOX6 + nivolumab) for a period of 12 weeks, once every 2 weeks, and will undergo surgery after 4 weeks.
A retrospective study was done on the medical records for 24 rectal cancer patients underwent robotic proctectomy from September 2017 to July 2018 at the First Affiliated Hospital of Xi'an Jiaotong University.In the same department,a total of 25 patients who treated with laparoscopic proctectomy and 24 patients underwent open proctectomy were were selected as controls in a 1:1:1 ratio. Comparing the perioperative conditions and hospitalization related costs of the three groups.
Our objective in this study is to identify an optimal ultrasound spectroscopy parameter that can be used as an early predictor of pathological complete or partial response in men with prostate cancer and men and women with rectum and head and neck cancers receiving treatment radiotherapy. We have previously demonstrated that high-frequency ultrasound and spectroscopy, and recently conventional-frequency ultrasound and spectroscopy may be used to detect cell death in vitro, in situ and in vivo. The method can detect different forms of cell death and has been demonstrated to be sensitive to apoptotic, necrotic and mitotic cell death. The main goal, as described above, is to select the best ultrasound spectroscopy parameter to use as an early predictor of pathological complete response
Colorectal cancer is one of the most frequently diagnosed cancers and a major cause of cancer deaths worldwide. Recurrence after curative surgery is one of the major factors affecting the long-term survival and its frequency is estimated to be 22.5% at 5 years. of which 12% have local recurrence. The overall survival in case of recurrence of 11% at 5 years. Several patient-, tumor-related and treatment-related prognostic factors have been found to be associated with the risk of recurrence of rectal adenocarcinoma. Some of these factors such as TNM stage, lymphatic and perineural invasion and vascular emboli have been found to affect recurrence free survival in most studies. While the impact of other factors such as distal resection margin, tumor size, extra capsular spread and neoadjuvant chemoradiotherapy on recurrence remains controversial. Moreover, most of the previous studies on prognostic factors have been from American and European countries with very little data from African countries. Recognition of these factors helps in identification of high-risk patients who require close and more rigorous postoperative surveillance. Hence this study was conducted to determine the factors affecting recurrence after curative resection of rectal cancer in African population.
In the Low Anterior Resection of rectum for cancer, the section level of IMA and the need of SFM is still debated. The aim of this study is to explore the different impacts of high and low ligation with peeling off vascular sheath of inferior mesenteric artery (IMA) in low anterior resection of the rectum for cancer. This study purpose to demonstrate that low IMA ligation, sparing of left colic artery (LCA) and selective SFM results in higher anastomotic leakage rate than high IMA ligation with routine SFM (with the difference of more than 5%).
