Active clinical trials for "Rectal Neoplasms"

Colorectal cancer ranks the second lethal cancer and third prevalent malignant tumour worldwide, Despite of different odern modalities for diagnosis,large number of cases diagnosed at metastatic advanced stage . New treatment approach has been discovered habe been discovered making a huge revolution in metastatic colorectal cancer represented by targeted therapy including anti_EGFR ,anti_angiogenic and kinase inhibitors .

Quality of life and risk factors for developing major LARS are explored. Therapeutic options were explored in the cohort experiencing major LARS

Colorectal cancer is the third most frequently diagnosed type of cancer in the world. Recent developments in the treatment of cancers suggest that immune checkpoint inhibitors will play an important role. Many studies have documented many types of soluble receptors and ligands that can be detected in plasma in cancer, and plasma levels of these molecules correlate with cancer severity. There is only one study in the literature evaluating the status of soluble immune control points in patients with rectal cancer. The aim of this study is to investigate the role of serum immune checkpoints before neoadjuvant therapy in predicting clinical response in patients with rectal cancer. In this way, it is aimed to show whether immune checkpoints are predictive markers that can predict response to neoadjuvant therapy in patients with stage II-III rectal cancer.

The investigators are undertaking a multi-center, 13000 subject validation study of several biomarkers for early detection of colon cancer. There are stool based biomarkers and blood based biomarkers being validated in this study. The biomarkers will be compared with colonoscopy and with FIT (fecal immunohistochemistry) tests which are the current standards for colon cancer screening. This is an NCI-early Detection Research Network funded project. The population targeted for this study are those persons undergoing colonoscopy for screening. Prior to colonoscopy or even prepping for colonoscopy, subjects will provide blood and stool samples as well as specific data regarding their GI and general medical history and concomitant medications. If subjects are interested in participating, arrangements will be made to see them. The informed consent process will take place, blood will be obtained, data will be obtained, and the stool kit described and given to the subject to take home. Stool samples will be sent back to the University of Michigan using prepaid mailing labels.

The purpose of this study is to determine whether additional Dexmedetomidine to patient controlled analgesia can reduce fentanyl consumption.

This observational study is a follow-up study of protocol ML18280. Survival data of patients who took part in and concluded study ML18280 will be collected for up to 5 years after LPLV of ML18270.

A research study of rectal cancer perfusion (how blood flows to the rectum over time). We hope to learn whether perfusion characteristics of rectal masses may be predictive of response to treatment and whether rectal perfusion characteristics can be used to follow response to treatment.

RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment. PURPOSE: This research study is looking at protein expression in tumor tissue samples from patients with stage II or stage III rectal cancer enrolled in clinical trial SWOG-9304.

Traditionally bowel preparation before surgery of rectal cancer could be troublesome for patients especially for patients with kidney and cardio- vascular diseases, where salt and electrolyte balance can be a problem. Cleaning the bowel without complications for the patient is one of the aims for this study. The other aim is to see if patient nutritional status improves with nutritional drinks as a complement to food intake 4-6 weeks before surgery.

This study is for patients with advanced or stage II and III colon or rectal cancer. The primary purpose of this research study is to determine if a particular protein in the patient's blood will change when they receive treatment with a drug called oxaliplatin, which is used to treat the colon or rectal cancer. This protein is called ERCC-1. It is thought that the amount of this protein in the blood could influence the manner in which the patient responds to oxaliplatin.
