Active clinical trials for "Colorectal Neoplasms"

The purpose with this study is to evaluate treatment with radio chemotherapy (oxaliplatin and capecitabine) given concommitant with radiotherapy in patients with gastrointestinal tumors. The trial consists ot two separate studies; CORGI-U in patients with stomach- bile ducts- gallbladder and pancreas cancer, and CORGI-L in patients with colorectal cancer. CORGI-U will be designed as a phase-I-II-study,in which the first part will be a chemotherapy dose finding study, followed by a phase II part to establish response rates. All subjects receives radiotherapy concommitant. CORGI-L is a phase II trial, in which patients are treated with chemotherapy at fixed doses with radiotherapy concommitant.

The fluoropyrimidines 5-fluorouracil (5FU) and capecitabine (Cp) are among the most commonly used anticancer drugs. Still, there is much controversy about the correct dosing, and the fact that a minority of patients experience severe, sometimes even lethal toxicity following treatment. One important factor predisposing patients to severe toxicity is deficiency in the 5FU-catabolic enzyme dihydropyrimidine dehydrogenase (DPD). Our group identified 4 DPD risk alleles in over 300 Swiss cancer patients, that resulted in a 8-times increased risk of experiencing severe toxicity from 5FU or Cp. In patients receiving 5FU as a continuous infusion, there are accumulating data that keeping the AUC of 5FU between 20-30 mg*h/L is beneficial in terms of treatment toxicity and activity. In this study, patients carrying at least 1/4 DPD risk alleles will receive a 50% dose reduction of either 5FU or Cp, with the potential of later dose increases in the abscence of severe toxicity. Additionally, patients receiving i.v. 5FU will undergo therapeutic drug monitoring at the end of the 2-day continuous infusion, with subsequent dose adaptations to target a 5FU AUC of 20-30 mg*h/L. The primary study objective is to reduce the incidence of severe treatment-related toxicity from 13% (in historical controls) to 5% in study patients.

The purpose of this study is to investigate whether TAC plus FOLFOX4 are able to improve resection rate and overall survival in patients receiving primary colorectal tumor resection than given FOLFOX4 only.

Investigation into prehabilitation by increasing the supervision of exercise in patients undergoing colorectal resection for cancer and comparing with patients involved in a rehabilitation group receiving exercise after surgery.

The purpose of the study is to determine whether a quality of life pathway with defined diagnostic and therapeutic options improves quality of life in colorectal cancer patients during follow-up.

The goal of this clinical research study is to find the highest tolerated dose of heated intra-abdominal oxaliplatin that can be given to patients with colon cancer. Researchers also want to learn more about the ways that pediatric and young adult colon cancer may be different from colon cancer in adults.

The purpose of this study is to prove whether general anesthesia combined with epidural anesthesia could better maintain body balance of Th1/Th2 and Treg/Th17 compared with general anesthesia, so as to reduce the surgical stress-related immunosuppression, and to improve the prognosis.

This is a multicentre, open-label, Phase I/II study of enadenotucirev in patients with either solid tumour of epithelial origin not responding to standard therapy or for whom no standard treatment exists (Phase I dose escalation stage Single cycle), mCRC not responding to standard therapy (Phase I dose escalation Repeat cycle cohort expansion stage ), mCRC not responding to standard therapy or advanced or metastatic bladder cancer not candidate for chemotherapy (Phase Ib) or mCRC in stable disease or partial response after 3-4 months of first line standard of care chemotherapy (Phase II).

The purpose of this study is to understand the role bacteria that normally live in the colon may play in colorectal cancer risk, in addition to the hereditary risk to colorectal cancer. The investigators will collect stool specimens as well as additional colon biopsy specimens during the patient's scheduled colonoscopy procedure. The investigators will also collect a questionnaire about diet and lifestyle. The samples will be used to study the impact of diet on naturally-occurring oral and gut bacteria and their influences on human health including risk of cancer.

A randomized, controlled clinical trial comparing lymphadenectomy with extended inferior mesenteric artery ligation (complete mesocolon excision: which includes lymphoma tissue from the origin of the inferior mesenteric vein) with conventional locoregional lymphadenectomy in patients undergoing laparoscopic sigmoidectomy for sigmoid cancer.
