Filter by:Gastrointestinal cancers such as colon cancer and liver cancer cause many deaths in the US. Testing could catch these cancers early, helping people live longer. The goal of this study is to compare two different ways of getting more people tested for these cancers: 1) by directly reaching out to the people who need testing or 2) by helping providers fix issues that hold up testing. The main question it aims to answer is: how should healthcare systems go about choosing one or the other? Researchers will look at cancer testing rates over time at sites that are trying these different approaches. They will also survey and interview participants from these sites.
The goal of this observational study is to evaluate the short-term outcomes and long-term outcomes of robot-assisted right colon group for cancer compared to laparoscopic-assisted right colon group. This is a large sample study based on ten years of clinical data. The main question it aims to answer is: What are the advantages of da Vinci robot right hemicolectomy compared to laparoscopic right hemicolectomy, and is there a difference in long-term efficacy between the two methods.
Colorectal cancer is one of the most frequent malignancies, with a rising proportion of elderly patients in an aging society. In this study, the investigators attempted to find out the relationship between immunologic factors and recovery using various parameters impacting the treatment in elderly patients.
Patients with advanced colorectal cancer or pancreatic cancer who are receiving oxaliplatin-based chemotherapy will be included. The research participants in this study will consume probiotics along with safety and anti-cancer agent side effect-related questionnaires, blood, and fecal sample collection for up to 12 weeks from the date of registration. The total duration of participation for research subjects is 12 weeks.
Colorectal cancer (CRC) is the 3rd most common cancer in France. Treatment of CRC relies primarily on surgical removal of the primary tumor and chemotherapy is the current standard of care for synchronous metastatic disease. Overall survival remains strongly correlated with the tumor stage at the time of surgery, from 90% at five years for localized disease (stages 1 and 2), to around 20% for metastatic forms of the disease (stage 4). Recent research in cancer highlights the role of the immune system in the development, evolution and fate of tumors. Understanding the nature of interactions between different immune cells infiltrating the tumor is important for the development of innovative therapies. Recently, the consensus molecular classification of CRC confirmed the importance of the immune response in CRC by showing that a "high immune response" is a good prognostic indicator for patients with this pathology. However, immunotherapies are effective for only a minority of patients with metastatic CRC. Indeed, anti Programmed cell Death 1 (anti-PD-1), -PD-L1 immune checkpoint blocking antibodies have only shown effectiveness in patients with microsatellite instability (MSI), which only represents 5% of metastatic CRCs. Thus, the aim of this study is to better understand the role of the immune system on the development of CRC and its possible modulation to treat or prevent metastatic recurrences.
Patients in the Prospective Dutch ColoRectal Cancer cohort (PLCRC) with non-metastatic colon cancer that gave consent for additional blood withdrawals are enrolled in the observational PLCRC-MEDOCC substudy. In this study, blood is collected before surgery, after surgery and during follow-up. Within PLCRC-MEDOCC, patients with stage II colon cancer that are not considered to have an indication for adjuvant chemotherapy, can be included in the MEDOCC-CrEATE subcohort under the condition that they gave informed consent in PLCRC for biobanking of tissue and for future studies (Trial within Cohorts design). Patients included in MEDOCC-CrEATE will be randomized 1:1 to the (A) ctDNA-based treatment group versus (B) the standard of care group. A total of 1320 patients will be randomized. Patients randomized to the ctDNA-based treatment group will have their post-surgery samples analysed directly after informed consent for MEDOCC-CrEATE. All patients with detectable ctDNA will be offered adjuvant chemotherapy (3 months CAPOX). Patients with undetectable ctDNA will receive routine follow-up at the surgical department. The aim of this Trial within Cohorts study is to investigate how many patients with detectable ctDNA after surgery start with adjuvant chemotherapy.
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.
Colonoscopy is the current standard method for evaluation of colonic disorders such as colorectal cancer, IBD, polyps, and other conditions.
This study aims to explore through a multi-center, randomized controlled clinical study whether robot-assisted radical resection of right colon cancer is superior to laparoscopic surgery in terms of surgical quality and oncological prognosis.
Colorectal cancer (CRC) is a leading cause of cancer-related mortality worldwide. Microsatellite instability or mismatch repair deficiency occurs in 20% of CRC, and is predominantly found in non-metastatic tumors. The success of the CheckMate 142 and KEYNOTE-177 clinical trials has shifted the treatment paradigm of the MSI/dMMR CRC, which has led to the adoption of immune checkpoint inhibitors (ICI) by international treatment standards. However, despite the encouraging effects of ICI, up to 30% of patients are resistant to treatment and exhibit rapid disease progression shortly after starting ICI. On the other hand, around 30% of patients treated with ICI demonstrate prolonged responses to the treatment with a duration of response of over 40 months. Furthermore, for ~10% of patients, treatment with ICI results in pseudo-progression - a phenomenon of a short-term increase followed by the decrease of the tumor volume. Currently, the mechanisms and biomarkers associated with the response or resistance to ICI in MSI-positive CRC are largely unknown. Select studies suggest that BRAF mutations (specifically, BRAF p.V600E) might negatively affect the patients' progression-free survival following ICI, however, these data are premature. The primary hypothesis is that the clonal heterogeneity and the evolution of MSI status of MSI-positive CRC will play a role in the development of ICI treatment resistance. The primary objective of the study is to investigate the dynamics of MSI status in serial liquid biopsy samples from patients with MSI-positive tumors receiving ICI.
