The diversity of definitions for the rectosigmoid junction is becoming a major obstacle to the standardization of optimal treatment of rectal cancers. The aim of this study was to determine the average height of the sigmoid take-off and its association with individual factors. Patients diagnosed with rectal and sigmoid colon cancer in our center from January 2010 to December 2018 were retrospectively enrolled in the cancer group. The results of 200 controls without colorectal disease were also reviewed (normal group). The distance of different landmarks and margins of cancer from the anal verge were retrieved from computed tomography (CT), magnetic resonance imaging (MRI), and endoscopy findings.
In this study, investigators utilize a radiopathomics integrated Artificial Intelligence (AI) supportive system to predict tumor response to neoadjuvant chemoradiotherapy (nCRT) before its administration for patients with locally advanced rectal cancer (LARC). By the system, whether the participants achieve the pathologic complete response (pCR) will be identified based on the radiopathomics features extracted from the pre-nCRT Magnetic Resonance Imaging (MRI) and biopsy images. The predictive power to discriminate the pCR individuals from non-pCR patients, will be validated in this multicenter, prospective clinical study.
This prospective randomized, open-label, multicenter, phase II clinical trial investigates the safety and tolerability of standard neoadjuvant chemoradiotherapy (CRT) with sequential ipilimumab and nivolumab in rectal cancer.
Colorectal cancer is the most-common cancer of the gastrointestinal tract. The number of positive lymph nodes and total number of lymph nodes retrieved are important prognostic factors. In patients who do not receive preoperative chemoradiation, the total number of lymph nodes should be more than 12 nodes to predict accurate staging. In cases of locally-advanced rectal cancer when patients receive neoadjuvant chemoradiation it is sometimes impossible to retrieve adequate amount of lymph nodes due to the chemoradiation effect. Therefore, this study was to evaluate and predict survival rates based on positive lymph node ratio.
This 12-week, exercise study will assess the feasibility of a home-based high-intensity interval training (HIIT) program among colorectal cancer survivors and explore the impact of home-based HIIT compared to a standard home-based moderate-intensity continuous aerobic exercise program on physical outcomes linked with survival from colorectal cancer and surrogate blood markers of colorectal cancer recurrence. HIIT is a type of aerobic exercise that includes short bursts (i.e. 1-4 minutes) of vigorous exercise followed by longer periods of moderate to lower intensity exercise (i.e. 1-10 minutes). Participants in this study will be randomly assigned into a personalized home based exercise program - either high-intensity interval training (HIIT) or moderate-intensity continuous aerobic exercise (MICE). This pilot study will provide us with preliminary evidence for a larger trial aimed to compare the effectiveness of these two different types of home-based exercise programs on physical outcomes linked with survival, quality of life, and surrogate blood markers of colorectal cancer recurrence.
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.
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.
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.
