Filter by:The FORTRESS trial (NG-350A-03) is an open-label, single-arm, and multicentre trial of NG-350A in combination with chemoradiotherapy (CRT) in adult patients with locally advanced rectal cancer (LARC) and at least one risk factor for local or distant recurrence.
This study evaluates the reliability of functional MRI measurements in pelvic disease through quantifying repeatability and reproducibility, using healthy volunteers. The aim is to provide insights into the consistency of results across sessions and observers, informing the trustworthiness of functional MRI in assessing pelvic disease and particularly rectal cancers and guiding protocol optimization.
Introduction: The standard treatment for rectal adenocarcinoma is total mesorectal excision (TME), a technique involving resection of the rectum, with or without a temporary or permanent stoma. TME is associated with high morbidity and genitourinary alterations. On the other hand, transanal endoscopic surgery (TEM) allows access to tumors up to 20 cm from the anal margin, with much lower postoperative morbidity and without the need for ostomy. For T1, N0, M0 rectal adenocarcinomas without poor prognostic factors, TEM is the technique of choice. However, recent studies have described local recurrences of up to 20%. Our group, TAUTEM, has just completed a phase III clinical trial in T2-T3ab, N0, M0 rectal cancer, comparing preoperative chemoradiotherapy (CRT) and TEM versus TME, with very positive results in terms of postoperative morbidity, quality of life, and a local recurrence rate of 7.4%, not inferior to TME. These results encourage our TAUTEM group to launch a similar project at the T1, N0, M0 stage, comparing standard TEM treatment versus QRT and TEM, aiming to improve rectal preservation outcomes and enhance results regarding local recurrence, distant recurrence, and oncologic survival. Method: Prospective, controlled, randomized phase III multicenter clinical trial. Patients with rectal adenocarcinoma within 10 cm of the anal margin and up to 4 cm in size, staged as T1, N0, M0, will be included. These patients will be randomized into two groups: TEM after CRT and TEM alone. Postoperative morbidity and mortality, CRT side effects, and quality of life will be recorded. The minimum follow-up will evaluate rectal preservation and local recurrence and survival at two and three years. The sample size calculation for the study will be 106 patients. Conclusions: The aim of the study is to improve oncological outcomes in stage T1, N0, M0 rectal cancer through preoperative chemoradiotherapy associated with local surgery (TEM).
The goal of this clinical trial is to learn if neoadjuvant Fruquintinib and Tislelizumab combined with mCapeOX works to treat mid-high pMMR/MSS locally advanced rectal cancer patients compared with CapeOX. It will also learn about the safety of neoadjuvant Fruquintinib and Tislelizumab combined with mCapeOX. The main questions it aims to answer are: - Does neoadjuvant Fruquintinib and Tislelizumab combined with mCapeOX improve the pCR rate of mid-high pMMR/MSS locally advanced rectal cancer patients? - What medical problems do participants have when receiving neoadjuvant Fruquintinib and Tislelizumab combined with mCapeOX? Researchers will compare Fruquintinib and Tislelizumab combined with mCapeOX to CapeOX to see if neoadjuvant Fruquintinib and Tislelizumab combined with mCapeOX works to treat mid-high pMMR/MSS locally advanced rectal cancer patients. Participants will: - Receive Fruquintinib and Tislelizumab combined with mCapeOX or CapeOX before surgery up to 4 cycles - Receive radical operations and three years follow-up - Keep a diary of their postoperative pathology results and survival
The study aims to recruit 60 Spanish speaking individuals who identify as Latinos, are older than 18 years old and attend the Saint Thomas More (STM) Church in Chapel Hill. Study participants will be asked to attend an educational session at STM Church during which their baseline knowledge on colorectal cancer (CRC) and willingness to participate in cancer clinical trials (CCT) will be assessed through a questionnaire in Spanish. Following this, participants will watch three educational videos on CRC in Spanish. After watching the videos, CRC knowledge and willingness to participate in CCTs will be reassessed. Thirty +/- 7 days after participation in the educational session, participants will be invited back at STM Church in order to complete a follow-up questionnaire assessing CRC knowledge, willingness to participate in CCTs and perceived barriers preventing Latinos from participating in CCTs. Twenty of the 60 recruited participants will be asked to participate in a qualitative one-on-one interview aimed at identifying barriers preventing Latinos from participating in CCTs. It should be noted that cancer is the leading cause of death in the United States (US) Latino community, with CRC accounting for 10% of this overall mortality. Despite this, Latinos suffer from disparities in access to care, cancer screening, treatment, and representation in CCTs. In fact, although Latino individuals are among the largest and fastest growing communities of color in the US, currently comprising 18.7%, their representation in CCTs remains low. This is of concern because: 1) advances arising from trials with limited Latino representation may not be applicable to the Latino population, and 2) decreased Latino participation in CCTs may delay Latino access to novel therapies in a timely fashion. The investigators conducting this study believe that low cancer-specific health knowledge may be impacting Latino representation and willingness to participate in CCTs and can be addressed through culturally and linguistically appropriate community-based educational interventions. Latino CCT underrepresentation is a multifaceted phenomenon and bidirectional barriers at the physician-, healthcare system-, and patient-level are significant contributors. Therefore, understanding the multiple driving forces and barriers is essential to identifying potential targets for improvement.
Most digestive cancers show (over)expression of the tumour marker carcinoembryonic antigen (CEA). Therefore, interest in CEA-targeting tracers has increased over the past years. CEA-targeting tracers can be used for preoperative, intra-operative and postoperative imaging purposes. This study focusses on both preoperative and intraoperative multimodal imaging and image-guided surgery in patients with rectal cancer or pancreatic cancer.
This is an open-label, multi-center, single-arm clinical study. All patients received concurrent chemoradiation therapy (CRT) followed by 4 cycles of tislelizumab combined with CAPOX, then underwent clinical response assessment. Patients who achieved CR (cCR+ pCR confirmed by local resection of ncCR) continue tislelizumab combined with CAPOX for another 4 cycles and tislelizumab for 9 cycles, then Watch and Wait. Patients who did not achieved CR underwent total mesorectal excision (TME).
The purpose of this process is to clarify the characteristics of gut microbiota changes in patients with locally advanced rectal cancer undergoing preoperative neoadjuvant treatment, and to identify key bacterial species closely related to sensitivity to radiotherapy. This aims to elucidate the mechanism linking gut microbiome dysbiosis with radiotherapy sensitivity, thereby providing new combined treatment strategies to enhance the efficacy of radiotherapy.
The goal of this clinical trial is to learn if using topical tretinoin will help patients with colorectal cancer who are experiencing an acneiform rash as a side effect of their treatment. Researchers will compare the use of tretinoin on one side of the face to the use of a placebo on the other side of the face to see if there is an impact.
In the era of laparoscopy, ileostomy via specimen extraction site has been proposed as a novel approach for temporary ostomy creation to prevent anastomotic leak after laparoscopic low anterior rectal resection. Whether suturing the layer of the peritoneum and anterior rectus sheath affects the safety of this novel approach has not been investigated.
