Active clinical trials for "Rectal Neoplasms"

RATIONALE: Learning about quality of life, symptoms, and health behaviors in colorectal cancer survivors may help to determine the long-term effects of colon and rectal cancer treatments and may help to improve the quality of life for future cancer survivors. PURPOSE: This clinical trial is looking at patient-reported outcomes in long-term survivors of colon and rectal cancers.

The purpose of this study is to assess the effect of palliative pelvic radiation on symptoms and quality of life among patients with incurable prostate and rectal cancer.

This study was conducted to compare the significance of lymph node ratio and absolute count of positive lymph node count on overall survival in patients with rectal cancer who underwent resection with curative intent

Data on disease recurrence was collected for all primary rectal cancer patients diagnosed in the Netherlands over the first six months of 2015. Three-year cumulative incidence, risk factors, treatment and three-year OS of locally recurrent rectal cancer were determined.

The aim of this retrospective cohort-study is to assess the effects of AL and its severity divided according the ISREC-classification on the long-term oncological outcome.

Neoadjuvant radio-chemotherapy (NRCT) represents a milestone in the treatment of selected rectal tumours. Ideal time interval between the end of NRCT and surgery is still debated; a 6-8 weeks time interval is considered optimal, but shorter or longer intervals have been associated with better oncological outcomes. Moreover, there is a lack of data about clinical postoperative outcomes and different time intervals after the end of NRCT. Here, effect that different time intervals have on postoperative complications with particular regard to the anastomotic dehiscence have been evaluated. Methods One hundred-sixty-seven patients underwent surgery after long-course NRCT. Three different time intervals were considered: (0-42; 43-56; >57 days).

The incidence of rectal cancers is at 15,000 new cases per year in France of which 10 to 15% are locally advanced (T4bNxM0) at the moment of diagnosis. The rate of invaded resection margins (R1) for these locally advanced and fixed rectal tumours varies from 10 to 20%. The invasion of the resection margins triples the risk of local recurrence. In the absence of surgical treatment, the 5-year survival rate for patients having had pelvic recurrence of rectal cancer is lower than 4% whereas it varies from 35 to 40% in cases of curative resection. The care and management of locally advanced and fixed rectal tumours and pelvic recurrence of rectal cancer constitutes, therefore, in the absence of recommendation, a difficult therapeutic problem with great variability in the methods of care and management around the world. These variations in practice can be explained by structural and organizational differences, as well as cultural dissimilarities. With regards to the organization of its healthcare system, Australia is shown to be a leader as regards the care and management of locally advanced and fixed rectal tumours and pelvic recurrence of rectal cancer.

The purpose of this study is to determine whether 18F-FDG-PET-CT and texture analysis of MRI performed 9 weeks after Neoadjuvant Chemo-radiotherapy in patients with locally advanced rectal cancer has the ability to identify patients with Complete Response.

The purpose of this study is to investigate if PET/CT and MRI scans performed early in treatment and six weeks after treatment can predict the response of rectal cancer following chemotherapy and radiotherapy. This will help doctors to better tailor treatments for rectal cancer in the future.

This pilot clinical trial studies comprehensive gene sequencing in guiding treatment recommendations in patients with metastatic or recurrent solid tumors. Studying samples of blood and tissue from patients with cancer in the laboratory may improve the ability to plan treatment.
