Filter by: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
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.
The use of chemoradiotherapy (CRT), in combination with surgery is the standard of care in the treatment of locally advanced rectal cancer. However some patients don't respond well to radiation. More advanced radiotherapy techniques, that result in fewer toxicities, means that we are now able to combine new anti-cancer agents into standard treatment. Targeting the tumour early in this way has the potential to improve response rates. Enadenotucirev is a specific type of anti-cancer virus that only targets cancer cells. It acts in the same way as any virus and can only survive by replicating inside cancer cells and not normal, non-cancerous cells. This means that it can selectively target and destroy tumours, without directly affecting normal cells. It also has the ability to attract cells from the body's immune system to help fight the cancer. The addition of enadenotucirev to standard chemoradiotherapy treatment may have a combined effect on the cancer cells with potentially few, additional side effects. This trial aims to determine the optimal dose and frequency of the virus to give by gradually increasing the number of doses each successive patient receives, and then increasing the dose of the virus itself. Each patient will receive a minimum of 3 doses, up to a maximum of 6, spread over the course of their 5 week standard chemoradiotherapy treatment. Patients will be closely monitored at all times to ensure that with each dosing group, there aren't excessive side effects. Patients will then undergo surgery as part of their standard of care and be followed up for up to 4-6 weeks post-surgery. This trial aims to determine the optimal dose and frequency that can then be used in future studies with the possibility of exploring the addition of Enadenotucirev to other chemoradiotherapy treatments.
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.
This trial aims to assess safety and efficacy of three-row circular staplers compared to two-row surgical stapllers in short-term and long-term perspective in patients with rectal cancer undergoing low anterior resection with stapled colorectal anastomosis. All the patients will undergo a low anterior resection. In a half of patients a colorectal anastomosis will be created with a three-row surgical circular stapler. In another half of patients a colorectal anastomosis will be created with a two-row surgical circular stapler.
Mindsets are lenses or frames of mind that orient individuals to a particular set of expectations and associations. This study aims to leverage specific and empirically supported mindsets (i.e., 'cancer is manageable' and 'the body is capable') to reduce distress and improve physical health and psychological wellbeing in patients with cancer being treated with curative intent. This intervention will take the form of several brief documentary style film segments which feature both cancer survivors and experts in the fields of Oncology, Psychology, and Psychiatry. Although no mindset-targeted interventions have been studied in cancer patients to date, other psychosocial interventions have demonstrated efficacy in treating emotional distress and improving quality of life in this population. However, compared with these standard interventions, mindset interventions need not be lengthy, complex, or costly to yield major effects. Thus, this project aims to lay the groundwork for future scalable and efficient interventions that can meaningfully reduce distress and improve health and wellbeing in this population.
The investigators' data from a phase I study of short course radiation therapy followed by chemotherapy showed 74% complete clinical response (cCR). Given the promising response rate, the investigators are evaluating short course radiation therapy (SCRT) followed by chemotherapy in a multi-institution phase II trial to validate the cCR rate of this treatment paradigm. SCRT has not been prospectively evaluated in non-operative management for patients with non-metastatic rectal adenocarcinoma.
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.
