Filter by: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.
RectSexQoL is a study aiming at determining the prevalence of female sexual dysfunction after rectal cancer surgery. It has the goal as well to analyse the impact of an intervention given by a sexologist to such patients.
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.
Rectal cancer is one of the most prevalent malignancies in the world, and its prevalence is rising. In more advanced cases neoadjuvant therapy is advised before to surgery, and radiotherapy is one of its cornerstones. For the treatment of rectal cancer, there are primarily two radiation techniques. Long-term radiotherapy is 50.4 Gy delivered in 28 fractions, while short-term radiotherapy is 25 Gy delivered in 5 parts. In earlier studies, these two radiation techniques were combined with various chemotherapy drugs, and a relative comparison was established. Total neoadjuvant treatment, or TNT, has been linked to a better outcome because of the significance of organ preservation. The aim of this research is to compare two TNT radiation techniques with the same regimen of treatment.
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).
Compare two arms: - Chemotherapy followed by tolinapant (ASTX660) in combination with Long-Course Radio Chemotherapy (LCRT), and - Tolinapant (ASTX660) in combination with Short-Course Radiotherapy (SCRT) followed by chemotherapy For each patient, the treatment arm will be allocated on the following basis: patients will be allocated to the chemotherapy followed by LCRT arm unless they present at least one of the following criteria: contraindication to receive mFOLFIRINOX (including intolerance to irinotecan and UGT1A1*28 polymorphism), age > 75, general condition incompatible with the radiotherapy schedule of LCRT. In such case, patients will be allocated to the SCRT arm. Tolinapant (ASTX660) will be administered orally once a day for 7 consecutive days every other week during 10 weeks (One week On / One week Off during 10 weeks). Both treatment arms will have a dose escalation part to determine the MTD and/or RP2D, followed by an expansion part where up to 21 subjects will be dosed at the RP2D. Both arms will enroll simultaneously.
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.
The primary objective of this research study is to explore the barriers encountered by specific demographic groups of rectal cancer patients during the engagement in clinical trials, which historically lack diverse representation. By carefully analyzing data from various demographic perspectives, this study aims to uncover patterns that impact the experiences of future rectal cancer patients. Active involvement in this crucial research is of utmost importance, as it can offer unique insights to enhance the participation and completion rates of rectal cancer patients in clinical study.
