Active clinical trials for "Rectal Neoplasms"

After resection of diseased segments of the large intestine, the continuity of the intestine has to be restored. This can be done by suturing or with so called stapling devices. In addition since 2 centuries compression rings are used to connect the intestine after resection. The NITICAR27 device is a novel compression anastomosis device. The investigators want to prove if this novel device can be compared to commonly used stapling devices concerning anastomotic leakage, bleeding and stenosis.

Determine if genotype-directed neoadjuvant chemoradiation, using information from the thymidylate synthase promoter polymorphism, result in a greater degree of tumor downstaging in high risk patients compared to historical controls.

The goal of this study is to learn how the treatment given to patients with recurrent rectal cancer affects their well being and quality of life.

The pilot study is designed to investigate the value of Neo-adjuvant Tomudez in combination with radiotherapy in patients with inoperable or recurrent rectal cancer in terms of response rate and increasing the resectability of initially inoperable rectal cancer.

Standard treatment for locally advanced cancer of the rectum is preoperative chemoradiotherapy with 5-Fluorouracil (5-FU) plus 4 cycles of postoperative chemotherapy with 5-FU. According to our previous study (CAO/ARO/AIO-94, published in the New England Journal of Medicine 2004; 351:1731-40) this treatment results in only 6% of local failures, yet, still 36% of all patients develop distant metastasis. Therefore, our new study (CAO/ARO/AIO-04) incorporates new drugs, i.e. 5-FU + oxaliplatin, in an effort to improve the control of distant metastases. It is our hypothesis that the rate of disease free survival will improve by 5 to 8% after 3 years of follow-up.

The goal of this clinical trial is to investigate total neoadjuvant therapy (TNT) using short course radiation therapy (SCRT) followed by full course of chemotherapy then surgery in locally advanced rectal cancer. The main questions it aims to answer are: Is total neoadjuvant treatment in this design safe & tolerable? Impact of this design on treatment related outcomes in terms of pathological and clinical responses.

This retrospective study aims to investigate whether initial imaging characteristics of rectal cancer on Magnetic Resonance Imaging (MRI) correlate with the underlying tumour pathology and oncological outcomes such as response to treatment. Using radiomic features, calculated using new high throughput analysis of previously acquired imaging, a statistically robust prognostic model will be created with the overall aim of developing imaging biomarkers.

This study proposeto integrate a variety of imaging quantitative indicators to establish a new MRI-based tumor response regression(mrTRG) classification method. The accuracy of the established mrTRG classification method according pathology TRG(pTRG) will be tested. The ability of the established mrTRG classification method to predict prognosis will also be tested.

The two surgical options for lower 1/3 rectal cancer is APR and sphincter sparing procedures. Intersphincteric resection is procedure to treat very low rectal cancer within 2 cm from the dentate line to avoid permanent colostomy,improves the quality of life with better genitourinary function. Neoadjuvant chemo-radiotherapy is routine for T3 cases.

The objective of this mechanistic study is to determine the impact of tecemotide (L-BLP25) administration on the mucinous glycoprotein 1 - (MUC1) specific immune response in subjects with newly diagnosed rectal cancer who are eligible for neoadjuvant therapy. Tecemotide (L-BLP25) is designed to induce an immune response that may lead to immune rejection of tumor tissues that aberrantly express MUC1 antigen. MUC1 is highly expressed in all colorectal cancers and since the adaptive immune system plays a role in the prognosis of rectal cancer, it is reasonable to speculate that tecemotide (L-BLP25) administration might boost the tumor-specific immune response and increase the number of tumor-infiltrating lymphocytes (TILs).
