A Questionnaire to Assess the Quality of Life of Rectal Cancer Patients With or Without Stoma

Rectal Cancer

The aim of the present prospective study was to evaluate the prediction accuracy of EORTC QLQ-C30/C38 questionnaire in rectal cancer patient(RC). This study was designed to investigate how the quality of life (QoL) of patients with rectal cancer changes with time after cancer or after stomia. Eligible subjects were consecutively enrolled in the investigators' Institute and subjected to EORTC QLQ-C30/C38 questionnaire.

Factors Predicting Recurrence in Rectal Cancer After Surgery

Rectal CancerRectal 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.

Rectal Cancer

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.

Safe Colorectal Surgery in the Elderly

Rectal Cancer

The objective was to evaluate the use and outcomes of robotic proctectomy compared to open and laparoscopic approaches for rectal cancer in the elderly. A retrospective cross-sectional cohort study utilizing the Nationwide Inpatient Sample (NIS; 2006-2013) was performed.

Assessment of Complete Response MRI Criterion After Neoadjuvant Therapy in Locally Advanced Rectal...

Rectal Neoplasms

Standard care for locally advanced rectal cancer consists in a neoadjuvant therapy followed by surgery. Morbidity and mortality remain high after rectal surgery, and often linked with quality of life impairment. 10 to 30% present a pathological complete response after neoadjuvant therapy. Some surgical teams propose "watch and wait" approach for patients selected with clinical complete responses criterion. The problem is to be sur the response is complete. MRI seems to be accurate to select complete responders. We will try to find MRI criterion of complete responses.

Evaluating Factors Affecting Survival in Colon and Rectum Cancer

Colon CancerRectum Cancer

Colorectal cancers are frequent among cancers of the gastrointestinal system. Whether there are any differences between survival in rectum and colon cancer patients is controversial. This study aimed to compare survival in the surgically treated rectum and colon cancers and determine the factors affecting survival.

Using Artificial Intelligence to Predict Rectal Cancer Outcomes

Rectal Cancer Stage III

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.

Blood Flow Path Reconstruction in Rectal Cancer

Rectal CancerSurgery1 more

89 patients with distal sigmoid and rectal cancer were referred in our observation and underwent MS-CTA between June 2020 and March 2022. We classified the distribution of LCA and confirmed whether there exists AMCA (accessory middle colic artery). Then we planned blood flow path based on the classification of LCA branches before operation. High ligation was applied in regular radical surgery. During operation, we carefully protect the bifurcation of ascending and descending LCA. Then we compared the planned blood flow path with the actual postoperative blood flow path to verify the mechanism we proposed previously.

Multicenter Study on Suprapubic Catheterization Versus Transurethral Catheterization in Laparoscopic...

Rectal CancerSurgery

Compared with traditional open proctectomy, laparoscopic surgery is associated with less pain, earlier recovery, and better cosmetic outcome, and its long-term oncologic outcomes have been demonstrated. However, the rate of urinary dysfunction after rectal cancer surgery was about 19-38% because of mesorectal excision. The type of drainage is unclear. Some studies show that the rates of urinary tract infection, second catheterization, and urinary symptom are lower with suprapubic catheterization (SPC) than with transurethral catheterization (TUC). Moreover,SPC allows for testing the bladder voiding without drainage removal. Furthermore,SPC using central venous catheter(CVC) is less invasive. Currently, there is lack of randomized controlled trial(RCT) to compare SPC with TUC. Therefore, investigators perform this prospective randomized trial to compare SPC using CVC with TUC in laparoscopic surgery for rectal cancer.
