Filter by:This trial (molecular characterization trial) focuses on rectal cancer, a common cancer that is treated with radiotherapy (RT) as standard of care and represents a setting in which to study the effects of RT on the immune system.
Prospective, open label, multi-dose, sequential dose escalation, single-center, Phase 1 trial
The goal of this clinical trial is to compare the efficacy of using polypropylene mesh for hernia prevention after stoma closure in patients with colorectal cancer and non-mesh repair. The main question it aims to answer is: can mesh help prevent hernia? Participants will be divided into 2 groups: with and without mesh using. They must be followed up for 2 years after enrollment in the study. Researchers will compare mesh and non-mesh groups to evaluate the benefits and harms of mesh using in hernia prevention.
A multicenter single-arm phase 2 study to evaluate safety and efficacy of the total neoadjuvant therapy of short course radiation therapy followed by neoadjuvant oxaliplatin/fluorouracil-based chemotherapy (CAPOX) for cT2 rectal cancer
Patients with locally advanced non-metastatic adenocarcinoma of the rectum undergoing chemoradiation therapy will be assigned to 2 groups: - the intervention group will be prescribed an individualized ketogenic eating plan to be followed throughout the treatment period - the control group will be prescribed a diet therapy plan treatment following the international guidelines of clinical nutrition, also to be followed during treatment
The Intersphincteric resection (ISR) technique is an alternative for anal preservation in ultra-low rectal cancer. The transanal total mesorectal excision (TaTME) technique might compensate for the deficiencies of ISR in terms of tumor spillage and poor surgical field exposure. Thus, the investigators perform ISR through a transanal endoscopic approach (taE-ISR), seeking to evaluate the value of this innovative technique in anal preservation in ultra-low rectal cancer.
Rectal cancer is one of the most frequent malignant tumors nowadays. There are several possible treatment options including chemotherapy, radiotherapy and surgery. Surgery for early stage rectal cancer can be either a radical surgery (RS) or a local excision (LE). A radical surgery removes the rectum including the tumor and the lymph nodes through which it spreads, improving survival but with a possible impact in the patients quality of life (QoL). A local excision only removes the tumor and a safety margin of healthy rectum. This has the potential to avoid the possible complications and QoL decrease. However there are some complications after a LE and also poor prognostic factors inherent to the tumor biology that can lead the surgical team to perform a RS after LE with worse outcomes. These are impossible to know before the procedure. The goal of this registry is to determine the frequency of these poor prognostic biological factors and complications in patients undergoing LE for early rectal cancer. The main question it aims to answer are: • How frequently does LE allow for rectum preservation? Participants will undergo LE for early rectal cancer when it is considered the best treatment by their surgeons according to their expertise and protocols. Patients will follow the standard treatment that would be given to them, and the biological prognostic factors and the appearance of complications will be recorded.
The TNTRect trial is a prospective observational study that will evaluate the outcome of MR-guided stereotactic body radiotherapy (SBRT) with a simultaneous integrated boost in a hypofractionated treatment of rectum cancer. Patients will be treated in 5 daily fractions of 5 Gy within an overall treatment time (OTT) of 5 days. A simultaneous integrated boost (SIB) till 30Gy will be delivered to the gross tumor volume. Patients will be treated with daily adaptive radiotherapy and online tumor gating on the MRIdian system (ViewRay Inc.). The aim of the study is to improve the complete clinical response rate to offer more patients an organ preserving approach. The primary endpoint is patient response to the treatment, assessed by endoscopy and MRI, or by medical pathology reports after potential resection was performed. As secondary endpoints local control, disease-free survival, overall survival and the patient's quality of life & hospital anxiety and depression will be measured.
The aim of this study is to evaluate the efficacy of a brief psychoeducational intervention to improve the self-efficacy of patients with locally advanced rectal cancer who are initiating multimodality treatment (e.g., total neoadjuvant therapy).
In the present study, the investigators will evaluate the efficacy, toxicities, and of online adaptive radiation therapy (ART) for patients with rectal cancer treated with neoadjuvant chemoradiotherapy.
