225 active trials for Rectal Cancer

Integrated Cancer Repository for Cancer Research

The iCaRe2 is a multi-institutional resource created and maintained by the Fred & Pamela Buffett Cancer Center to collect and manage standardized, multi-dimensional, longitudinal data and biospecimens on consented adult cancer patients, high-risk individuals, and normal controls. The distinct characteristic of the iCaRe2 is its geographical coverage, with a significant percentage of small and rural hospitals and cancer centers. The iCaRe2 advances comprehensive studies of risk factors of cancer development and progression and enables the design of novel strategies for prevention, screening, early detection and personalized treatment of cancer. Centers with expertise in cancer epidemiology, genetics, biology, early detection, and patient care can collaborate by using the iCaRe2 as a platform for cohort and population studies.

Optimisation of Response for Organ Preservation in Rectal Cancer : Neoadjuvant Chemotherapy and Radiochemotherapy vs. Radiochemotherapy

Standard treatment of rectal cancer is rectal excision with neoadjuvant radiochemotherapy. A new concept suggests organ preservation as an alternative to rectal excision in good responders after neoadjuvant radiochemotherapy to decrease surgical morbidity and increase quality of life. The rational is the fact that 15% of patients have sterilized tumours after radiochemotherapy for T3T4 rectal cancer. The French GRECCAR 2 trial is the first phase III trial investigating this strategy: patients with T2T3 low rectal carcinomas (size ?4 cm) received 50 Gy with capecitabine and good clinical responders (?2 cm) were randomized between local and rectal excision. The main findings were: the rate of complete pathologic response was higher after radiochemotherapy for small T2T3 than for T3T4 tumours (40% vs 15% ypT0) and good pathologic responders (ypT0-1) were associated with zero positive mesorectal nodes. The objective of the new trial is to increase the proportion of patients treated with organ preservation by optimizing tumour response. As compared to Folfiri, tritherapy Folfirinox has been shown to enhance the response rate. In patients with colorectal metastases, response rate and R0 resection were twice higher, resulting in improved survival. Folfirinox also increases response and chance of R0 resection rates in initially unresectable colorectal metastases, compared to standard or intensified bi-chemotherapy regimens. Adding two months of neoadjuvant chemotherapy (Folfirinox) before radiochemotherapy, the investigators expect to increase chance of organ preservation rate, as compared to radiochemotherapy alone.

Impact of a Patient-Centered Program for Low Anterior Resection Syndrome A Multicenter Randomized Controlled Trial

After undergoing restorative proctectomy for rectal cancer, many patients are left with significant bowel dysfunction, known as Low Anterior Resection Syndrome (LARS). Increased LARS severity correlates with worse perceived global health status and quality of life (QoL). Among patients undergoing rectal resection with a permanent ostomy, there is evidence that supportive and educational interventions improve QoL, ostomy proficiency, self-efficacy and knowledge. However, evidence regarding the impact of such interventions in patients who undergo restorative proctectomy is lacking, despite the latter operation being far more frequently performed. The overall goal of this study is to evaluate the extent to which a LARS Patient-Centered Program impacts on patient-reported outcome measures (PROMs) after restorative proctectomy for rectal cancer. This is a randomized-controlled muticenter trial that will include patients who have undergone restorative proctectomy for neoplastic disease (benign or malignant) located in the rectum (0-15cm from the anal verge) with a diverting ostomy and who are scheduled for ostomy closure.

A Prospective Phase II Study of Individualized Neoadjuvant Chemoradiotherapy for Rectal Cancer Based on Recurrence Risk

Start: December 2020

Chemotherapy Followed by Pelvic Reirradiation Versus Chemotherapy Alone as Pre-operative Treatment for Locally Recurrent Rectal Cancer

GRECCAR 15 is focused on Locally Recurrent Rectal Cancer (LRRC) for patients with previous pelvic radiotherapy for the primary rectal cancer. This situation leads to a 20% higher risk of non-curative resection for the LRRC management (R1 status) impacting significantly the overall survival. The widespread use of neoadjuvant radiotherapy for primary rectal cancer introduces this new problem: the treatment of LRRC in previously irradiated area. The objective of GRECCAR 15 is to assess the efficacy of neoadjuvant chemotherapy followed by pelvic reirradiation versus neoadjuvant chemotherapy alone on the rate of curative surgery (R0) in previously irradiated patients with LRRC.

Transanal Total Mesorectal Excision for Rectal Cancer on Anal Physiology + Fecal Incontinence

Low Anterior Resection (LAR) surgery can be done using various techniques. The traditional technique for performing the surgery is through one or multiple incision(s) in the muscular wall of the abdomen. This will allow the surgeon to gain access to inside the belly (Abdominal cavity). The surgeon will start from above and go down until reaching the rectum located low in the pelvis. The surgeon will then cut out the rectum along with some of the tissue surrounding it and reconnect the bowel. An alternative new approach to perform Low Anterior Resection is called the Trans-anal approach. In this technique, a tube containing special surgical tools is introduced through the anus (back passage), while the patient is asleep. These tools are used to free the rectum up from its surroundings so that it can be removed. Taking out the rectum via the opening of the anus (Trans-anal) is a relatively new surgical approach. This new technique enables the surgeon to better see deep in the pelvis which makes it easier to remove the rectum and its surrounding outer tissues while protecting other important nerves and organs located in the pelvis. However, it also involves inserting a tube through the opening of the anus to perform the rectal dissection. The alternative traditional way of doing the operation does not involve inserting such a tube because the access to the pelvis and rectum is gained from above through incision(s) in the abdominal wall. The anal sphincter is the medical name for the muscle layers surrounding the opening of the anus. The anal sphincter functions as a seal that can be opened to discharge body waste and allow the passage of stool. A damage to the anal sphincter can result in inability to fully control bowel movements, causing stool (feces) to leak unexpectedly. Because the Trans-anal approach involves inserting a tube through the opening of the anus for the duration of the surgery, this can lead to a certain degree of stretch and damage to the anal sphincter muscles. The main aim of this study is to compare the effect of the these two possible approaches to perform "Low Anterior Resection" operation on the muscles of the anal sphincter and whether they are associated with stool seepage from the anus after the operation. Whether the patient is receiving the traditional or trans-anal approach is not related to the subject's participation in the study and is decided by the treating surgeon based on medical and surgical reasoning.

Multicenter Phase II Study of Transanal TME (taTME)

Radical rectal cancer resection, namely total mesorectal excision (TME), is the cornerstone of the treatment of resectable rectal cancer. In combination with chemotherapy and radiation treatment (CRT), complete TME with negative resection margins is associated with sustained local and systemic control even in locally advanced disease. Over the last 2 decades, laparoscopic and robotic techniques have been increasingly adopted due to reduced surgical trauma and faster patient recovery. Yet, both approaches are associated with equivalent postoperative morbidity and disturbances in sexual, urinary and defecatory function relative to open TME. Furthermore, laparoscopic and robotic TME remain associated with substantial conversion rates and variable rates of TME completeness as a result of the procedural difficulties reaching the low rectum from the abdominal approach. Transanal TME (taTME) with laparoscopic assistance was developed to facilitate completion of TME using a primary transanal endoscopic approach. Transanal TME uses a "bottom-up approach" to overcome the technical difficulties of low pelvic dissection using an abdominal approach. Published results from single-center taTME series and an international registry suggest the short-term procedural and oncologic safety of this approach in resectable rectal cancer. No multicenter phase II study has yet been conducted to validate the procedural safety, functional outcomes or long-term oncologic outcomes of this approach. Study Design: This is a 5-year phase II multicenter single-arm study to evaluate the safety and efficacy of low anterior resection (LAR) with taTME using laparoscopic or robotic assistance in 100 eligible subjects with resectable rectal cancer. Hypothesis: taTME is non-inferior to standard LAR with respect to the quality of the TME achieved.

The OPERa Study: Evaluating QoL After Rectal Cancer Surgery

Advances in rectal cancer management have significantly reduced morbidity and mortality. The most commonly performed operation for rectal cancer is restorative proctectomy (RP), leaving up to 70% with long-term bowel dysfunction called Low Anterior Resection Syndrome (LARS). LARS manifests as stool frequency, incontinence and difficult defecation. LARS, along with other functional impairments such as sexual and urinary dysfunction (SUD), can impact quality of life (QoL) and cause emotional distress. There is no well-established treatment strategy for LARS or SUD. High-quality longitudinal data on these sequalae are lacking, leading to variable estimates of their prevalence, risk factors and prognosis. Most studies are European, cross-sectional, lack pre-treatment evaluation and long-term follow-up, and use inconsistent assessment measures. Thus, a North American study that evaluates patients longitudinally from diagnosis will provide quality data to fill this knowledge gap. The main aim of the proposed study is to contribute evidence regarding the impact of LARS, SUD, emotional/financial distress, and patient activation on long-term post-treatment QoL in North American rectal cancer after RP. This study aims to address the following research questions: 1): How do North American rectal cancer patients who underwent RP experience changes in function (bowel, sexual and urinary), distress (emotional and financial) and QoL after RP from baseline through early and late timepoints following treatment? 2): How do patient-, disease-, treatment-, functional- and distress-related factors predict QoL at baseline and at early and late timepoints post-treatment? This multicenter North American, observational, prospective cohort study relies on validated patient reported outcome measures (PROMs) at diagnosis, during and post-treatment. Patients from 20 sites will be recruited over 2 years and followed for 3 years. The primary endpoint is QoL as measured by the European Organization for Research & Treatment of Cancer QoL questionnaire. We anticipate accrual of 1200 patients. Estimating a 30% attrition rate, in 1000 different simulated datasets and ?=0.05, we will be able to detect a 1 point difference in QoL 88% of the time (95%CI: 85.8, 90.0). Given that a 10-point difference is considered clinically significant, this sample size affords good precision. 1) QoL, LARS, SUD, emotional/financial distress will be measured at baseline, early (12 & 18 months) and late (2 & 3 years) timepoints. 2) Changes over time for each outcome will be studied using linear mixed models (LMM) and generalized LMM as appropriate to account for the hierarchical and longitudinal structure of the data. 3) Factors associated with QoL will be explored using LMM. 4) Impact of patient activation in relation to functional outcomes on QoL over time will be explored using a difference-in-differences approach. The study involves a multidisciplinary team who will provide expertise in research methodology, nursing, oncology and surgery. The main contributions of this study are 1) provision of reference baseline North American values for important rectal cancer PROMs for clinical and research use, 2) an understanding of the evolution of functional outcomes and QoL post-treatment to counsel patients peri-operatively and throughout survivorship, and 3) to provide the basis for future tailored programs to support rectal cancer survivors.

Neoadjuvant Treatment With Regorafenib and Capecitabine Combined With Radiotherapy in Locally Advanced Rectal Cancer

Despite treatment of locally advanced rectal cancer relapses are frequent. Several attempts to improve these results with therapy intensification have shown modest effect on disease free survival (DFS) and overall survival (OS). Recent studies with addition of sorafenib and cediranib revealed promising effect on tumor response with acceptable toxicity. Regorafenib is a multi tyrosine kinase inhibitor (TKI) with a broad mechanism of action. Therefore this trial investigates if similar results can be achieved as with sorafenib or cediranib.
