Active clinical trials for "Rectal Neoplasms"

This clinical trial studies the use of the financial impact assessment tool in patients with colorectal cancer that has spread from the primary site to other places in the body. Gathering information about patients with colorectal cancer over time may help doctors better understand the financial impact of cancer and help patients avoid financial problems during treatment.

The aim of this observational study is to retrospectively collect current survival data for 3995 primary rectal cancer patients who were extracted from 5097 rectal cancer patients admitted in Cancer Hospital, Chinese Academy of Medical Sciences from January 2000 to December 2010. Moreover, based on a Cox model, we want to develope a nomogram that predicts local recurrence, distant metastases, and survival for patients with rectal cancer treated with pre- or postoperative chemoradiotherapy (CRT).

The purpose of this study is to study which genes are abnormal in rectal cancer and see if this predicts how well chemotherapy and radiation will reduce the size of cancer and whether cancer recurs after surgery.

It can be difficult to obtain the perspective of patients who have had bowel surgery. This study is being done because the investigators are trying to find out whether patient-reported outcomes, (results reported to investigators by the patient), on a regular basis, will help the investigators provide better patient care and symptom management. Therefore, the purpose of this study is to determine if it is possible and if it is useful to their medical care for patients who have had bowel surgery to complete surveys about their symptoms on a regular basis. In this study the surveys are completed from home, by web or by telephone, every month for 6 months. The results of this study will guide the design of large research studies on cancer-related bowel function. The purpose of this study is to develop a bowel function questionnaire for patients with colorectal cancer. The questionnaire will be used in future clinical trials to assess bowel function.

The purpose of this study was to compare the long-term oncology outcomes and specimen quality of taTME and laTME in the treatment of middle and low rectal cancer by a large sample cohort. At the same time, the local recurrence following a primary rectal cancer resection was analyzed to respond to the concerns about the event of the national suspension for TaTME due to the high local recurrence rate in Norway.

The treatment of rectal cancer is developing rapidly in the Netherlands, as well as internationally. This is accompanied by an increase in complexity of diagnosis and treatment, particularly when the tumor is located closer to the anorectal junction. Within these developments there is an important role for quality evaluation, where continuous feedback is able to improve care for rectal cancer in the Netherlands. By supplementing data from the Dutch ColoRectal Audit (DCRA) with additional data concerning diagnostics and treatment of rectal cancer patients operated in the year 2016, the Snapshot Rectumcarcinoom 2016 aimed to assess the improvement in surgical and oncological outcomes.

This is a retrospective analysis of all patients diagnosed with LARC who received NCRT and had MRI scans between 2003-2014 at East Suffolk and North Essex NHS Foundation Trust. Region of interest was drawn around the tumor or its location on T2 MRI images. Six texture parameters were systematically extracted from Textural histograms of post-treatment scans. These parameters were examined to determine their ability to predict local recurrence and distant metastases through Kaplan-Meier survival curves and log-rank tests.

Rectal cancer represents 14,000 new cases a year in France. At diagnosis, 70% of patients have a locally advanced tumors T3-T4 and / or N + evaluated mainly by rectal MRI. These patients will benefit from a neo-adjuvant treatment by radio-chemotherapy. The complete histologic response rate (ypT0N0) after this neo-adjuvant treatment ranged from 15 to 27% and improved recurrence-free survival, remotely relapse-free survival, overall survival, and decreased local recurrence rate. In the case of full response diagnosis after neoadjuvant chemoradiotherapy 3 theoretical solutions exist: Total excision of the rectum and mesorectum (TME) This is the classic attitude with a low risk of local recurrence (5%) but functional complications occur in 25 to 60% of cases A simple monitoring ("Watch and Wait") by MRI, biopsy, rectoscopy ... This strategy was initially proposed to elderly patients considered inoperable but it has also been proposed in younger patients, operable, with a view to decreasing morbidity and sequelae. This attitude poses a likely overall risk of local recidivism. However, this higher risk of recurrence may be the result of imperfect identification of ypT0N0 patients. Local excision of the post-radiation scar also called closure lumpectomy with pathological analysis and possible secondary TME if no complete response. This last attitude has the advantage of allowing an anatomopathological verification of the treated lesion and to complete the treatment if necessary. In the case of ypT0 the local recurrence rate is low and in this case it is possible to consider rectal savings. The choice of the last two attitudes is therefore based on the correct identification of patients in complete response. The performance of the diagnosis of no complete response after radiochemotherapy is therefore fundamental and is the subject of this project wich consist of comparing he diagnostic performance for the identification of a complete lack of response [18F] -FDG-PET / MRI ypT0N0 to that of the classic attitude (MRI) 6 to 9 weeks after the end of a neoadjuvant chemoradiotherapy treatment of low and mid-rectal cancers in patients in whom clinical and endoscopic examination favor a complete response.

The purpose of this study is to establish a reliable method for detection of rectal cancer patients with aggressive tumor at risk of metastatic disease and death by functional MRI.

This is an observational study of tumor samples and MRI imaging in patients with colorectal cancers. A tumor sample, MRI scans, and treatment outcome data will be used for research purposes to see if it is possible to predict patients' response to treatment.
