Filter by:The purpose of this study was to investigate the effect of only local radical treatment of liver metastases combined with systematic treatment in the treatment of patients with multiple organ metastases of colorectal cancer, whether it can benefit the prognosis and explore the risk factors related to the prognosis.
The purpose of this study is to learn about the safety (the impact of the study drug on the participant's body), effects of the study drug alone or in combination with bevacizumab or sasanlimab, and to find the best dose. This study is seeking participants who have solid tumors that: - have advanced (cancer that doesn't disappear or stay away with treatment) or - has spread to other parts of the body (metastatic). This includes (but limited to) the following cancer types: - Non-Small Cell Lung Cancer (NSCLC): It's a type of lung cancer where the cells grow slowly but often spread to other parts of the body. - Colorectal Cancer (CRC): This is a disease where cells in the colon or rectum grow out of control. - Urothelial Cancer (UC): This is a cancer that starts in the urinary systems. - Melanoma: Skin cancer that develops when melanocytes (the cells that give the skin its tan or brown color) start to grow out of control. All participants in this study will receive the study medication (PF-07329640) as an IV infusion (given directly into a vein) at the study clinic every week for repeating 28-day cycles. Depending on which part of the study participants are enrolled in they will receive the study medication (PF-07329640 alone or in combination with other anti-cancer medications (bevacizumab or sasanlimab). Bevacizumab is given in the clinic as IV infusion every two weeks and sasanlimab is given as a shot under the skin every 4 weeks. Participants can continue to take the study medication (PF-07329640) and bevacizumab until their cancer is no longer responding. Participants who are taking sasanlimab may receive it for up to 2 years. The study will look at the experiences of people receiving the study medicines. This will help see if the study medicines are safe and effective. Participants will be involved in this study for up to 4 years. During this time, they will have a study visit every week. After they have stopped taking the study medication (at about at 2 years) they will be followed for another two years to see how they are doing.
To observe the PFS of yttrium [90Y] microsphere injection combined with FOLFIRI and bevacizumab in second-line treatment of CRLM.
The purpose of this study is to learn about the safety and effects of the study medicine alone or when given together with other anti-cancer therapies. This study also aims to find the best dose. This study is seeking participants who have solid tumors (a mass of abnormal cells that forms a lump or growth in the body) that: - are advanced (cancer that doesn't disappear or stay away with treatment) and - have a KRAS gene mutation (a change in the DNA of the KRAS gene that can cause cells to grow in very high numbers). This includes (but limited to) the following cancer types: Non-Small Cell Lung Cancer (NSCLC): It's a type of lung cancer where the cells grow slowly but often spread to other parts of the body. Colorectal Cancer (CRC): This is a disease where cells in the colon (a part of large intestine) or rectum grow out of control. Pancreatic ductal adenocarcinoma (PDAC): This is a cancer that starts in the ducts of the pancreas but can spread quickly to other parts of the body. Pancreas is a long, flat gland that lies in the abdomen behind the stomach. Pancreas creates enzymes that help with digestion. It also makes hormones that can help control your blood sugar levels. All participants in this study will take the study medication (PF-07934040) as pill by mouth twice a day repeating for 21-day or 28-day cycles. Depending on which part of the study participants are enrolled into they will receive the study medication (PF-07934040 alone or in combination with other anti-cancer medications). These anti-cancer medications will be given in the study clinic by intravenous (IV) that is directly injected into the veins at various times (depending on the treatment) during the 21-day or 28-day cycle. Participants can continue to take the study medication (PF-07329640) and the combination anti-cancer therapy until their cancer is no longer responding. The study will look at the experiences of people receiving the study medicines. This will help see if the study medicines are safe and effective. Participants will be involved in this study for up to 4 years. During this time, they will come into the clinic between 1 to 4 times in each 21-day or 28-day cycle. After they have stopped taking the study medication (at about at 2 years) they will be followed for another two years to see how they are doing.
This study was designed as a prospective, parallel two groups and randomized controlled study with an experimental-control group to evaluate the effect of yoga-based breathing exercise on pain, fatigue, insomnia and self-efficacy in individuals undergoing colorectal cancer surgery. The sample size of the study was conducted with 60 patients, 30 in the control group and 30 in the experimental group, according to the results of a similar study with the G*Power 3.1., 9.7 program, with α = 0.05, 80% power and 0.648 effect, and taking into account possible losses. was planned. Research inclusion criteria; Patients who underwent colorectal cancer surgery for the first time were those who were 18 years of age or older, had a mobile phone suitable for downloading the yoga-based breathing exercise video, used the same type and dose of painkillers, and volunteered to participate in the study. "Personal Information Form", "VAS Pain Scale", "Brief Fatigue Inventory", "Richard Campbell Sleep Scale" and "Health Promotion Strategies Used by Patients Scale" will be used to collect data. Participants assigned to the experimental group will be provided with breathing exercises using a protocol containing Yoga-based breathing exercises. In order to conduct the research, approval will be obtained from KTO Karatay University Non-Drug and Medical Device Research Ethics Committee, ethics committee approval and permission will be obtained from the institution where the research will be conducted. Participation in the study is voluntary and written consent will be obtained from the participants. The data will be evaluated in the IBM SPSS Statistics Standard Concurrent User V 26 (IBM Corp., Armonk, New York, USA) statistical package program. A level of p<0.05 will be considered statistically significant.
Background : In unresectable mCRC, a de-escalation strategy using maintenance or chemotherapy (CT) discontinuation in selected cases is considered as a valid option in non-progressive patients after a first-line induction of doublet CT + targeted agent (TA) (1-7). In this context, circulating tumor DNA (ctDNA) is considered very promising to optimize decision making. Indeed, ctDNA harbour the same main alterations of the tumor and has been recognized as biologically relevant to reflect tumor dynamics and therapeutic efficacy (8). As we and other groups reported in mCRC, that early variation of ctDNA during CT may be relevant to predict outcome (9-11). Indeed, patients with a ctDNA decrease from the first (C1) to the third (C3) cycles of CT (∆≥80% or ctDNA<0.1 ng/ml at C3) or without ctDNA detectable at C1 and C3 have significant better survival as compared to patients with less decrease or with ctDNA increase (10). ctDNA monitoring had never been prospectively evaluated to guide early adaptation in the treatment strategy in mCRC. Aim: A randomized phase III, open label, strategy trial of the superiority in overall survival (OS) adjusted on quality of life of an early treatment adaptation guided by ctDNA variation versus a standard management in unresectable left-side, MSS-BRAFV600E non-mutated mCRC treated by first-line doublet CT + TA. Patients and methods : -Main inclusion criteria will be (i) unresectable left-side and non-pre-treated mCRC (ii) MSS and non-mutated BRAFV600E tumor (iii) at least one measurable lesion (iv) ECOG 0-1 and adequate biological functions for first-line doublet CT + TA (antiEGFR if RAS WT, bevacizumab (BV) if RAS MUT). Randomization (1:1) between an experimental strategy guided by ctDNA variation with de-escalation (Arm A1 or A2) or switch of treatment (Arm A3) versus standard strategy (Arm B). The analysis of variation of ctDNA from C1-C3 will be centralized and detected using Digital PCR targeting hypermethylation of WIF1/NPY genes (10) in real-time in arm A and in second step in arm B. Randomization in Arm A: after 4 cycles of doublet + TA, non-progressive patients will be allocated to a strategy according to ctDNA value and variation from C1-C3: Arm A1: CT discontinuation (ctDNA normalization < 0.1 ng/ml or ctDNA not detectable) Arm A2 : maintenance with fluoropyrimidine + TA (ctDNA ≥ 0.1 ng/ml and ∆ctDNA≥ 80%). Arm A3 : ctDNA non-responders (∆ctDNA < 80% or increase) : switch of CT +/- TA. Randomisation in Arm B: at least 8 cycles of doublet CT + TA before adaptation of sequence at physician choice. Statistical considerations : with an expected median OS at 32 months (mean 37.6 months), a mean QoL at 70.0% in first-line mCRC, corresponding to 0.700 x 37.6 = 26.3 QALM or 2.19 QALY (SD 1.18 QALY), 408 patients are required (randomization 1:1) to show a gain of 4 months of quality-adjusted OS (4 QALM or 0.33 QALY) in experimental ctDNA strategy versus standard strategy (5% two-sided type I error rate, 81% power and 1.18 QALY SD). The secondary objectives will be: - To compare strategies (standard vs ctDNA guided) overall and in the subgroups of ctDNA response on 18, 24 and 36-months restricted mean of QoL-adjusted OS, OS, PFS, response rate, toxicity, Quality of Life and cost utility. - Bio-collection for further ctDNA analysis. Only cost of samples collection and their transportation to the resource center is requested. Further ancillary analysis will be subject to independent funding requests to evaluate : - ctDNA kinetics during the induction and its impact on outcome in overall population and in each arm - ctDNA changes between time points during de-escalation arms to determine thresholds of variations predictive of clinical and/or radiological progression. Conclusion: DIAMOND is a randomized phase III strategy trial to show the superiority in OS adjusted on quality of life of an early treatment adaptation guided by ctDNA versus a standard management in unresectable left-side, MSS-BRAFV600E non-mutated mCRC treated by first-line doublet CT + TA.
The aim of this study is to assess the safety and efficacy of human umbilical cord-derived allogenic mesenchymal stem cells (MSCs) engineered to express antitumor chemokine and co-stimulatory molecule. Following systemic administration, these cells are able to migrate into solid tumors such as colorectal tumors. Once enriched in the tumor, they will attract peripheral lymphocytes consisting of T and natural killer (NK) cells, and simultaneously stimulate the infiltrated lymphocytes for persistent and enhanced antitumor immunity. Thus, this MSC-based treatment provides a potentially effective and targeted immunotherapeutic strategy for tumors with unfavorable immune microenvironment and possibly poor response to immune checkpoint blockade (ICB). During this investigator-initiated trial (IIT), colorectal cancer patients will receive modified MSCs every 21 days via intravenous infusion. Increasing does will be tested in the initial cohort and an optimal dose will be chosen for the remaining patients.
The purpose of this platform study is to evaluate the safety, tolerability, pharmacokinetics (PK), and preliminary antitumor activity of novel RAS(ON) inhibitors combined with Standard(s) of Care (SOC) or with novel agents. The first three subprotocols include the following: Subprotocol A: RMC-6236 + 5-fluorouracil-based regimens Subprotocol B: RMC-6236 + cetuximab with or without mFOLFOX6 Subprotocol C: RMC-6236 + gemcitabine + nab-paclitaxel
There are significant barriers to colorectal cancer screening within underserved populations due to the cost, accessibility, and acceptability of screening methods. Patient-friendly approaches that minimize stress and discomfort for the patient are needed to enhance screening compliance and achieve an early diagnosis. The primary aim of this study is to examine whether the availability of a blood-based screening option, which can be done at the point of service and is familiar to patients, will improve patient compliance to recommended CRC screening
This is a prospective observational cohort study to explore the effects of sleep quality and mental status on early postoperative recurrence and prognosis in patients with colorectal cancer.
