Filter by:This pilot study will explore the preliminary efficacy of a colorectal cancer (CRC) screening intervention delivered by virtual health assistants (VHAs). Participants will include 750 African American patients in the US between the ages of 45 and 75 recruited through Qualtrics panels. The main research question is: How does the integration of different levels of dialect density of the linguistic features of African American English (AAE) influence the perceived credibility of a Black VHA. Four types of VHAs will be presented to our patients: a VHA with Standardized American English (SAE) linguistic features, a VHA with a low level of African American English (AAE) linguistic features integrated, a VHA with a high level of African American English (AAE) linguistic features integrated, and a text-only control condition. Survey questions will be used to obtain credibility judgments about VHAs post-interaction.
The dose escalation phase of this trial identifies the safety, side effects and best dose of ceralasertib (AZD6738) when given in combination with trastuzumab deruxtecan (DS-8201a) in treating patients with solid tumors that have a change (mutation) in the HER2 gene or protein and have spread to other places in the body (advanced). The dose expansion phase (phase Ib) of this trial compares how colorectal and gastroesophageal cancers with HER2 mutation respond to treatment with a combination of ceralasertib and trastuzumab deruxtecan versus trastuzumab deruxtecan alone. Ceralasertib may stop the growth of tumor cells and may kill them by blocking some of the enzymes needed for cell growth. Trastuzumab deruxtecan is a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug, called deruxtecan. Trastuzumab attaches to HER2 positive cancer cells in a targeted way and delivers deruxtecan to kill them. Ceralasertib and trastuzumab deruxtecan may be safe, tolerable and effective in treating patients with advanced solid tumors expressing the HER2 protein or gene.
Patients with refractory metastatic colorectal cancer or non-small cell lung cancer with liver metastasis treated with Trans-arterial Tirapazamine Embolization along with Pembrolizumab.
This is a phase Ib/II open label study. The escalation part will characterize the safety and tolerability of JDQ443 single agent and JDQ443 in combination with the other study treatments (TNO155 and tislelizumab) in advanced solid tumor patients. After the determination of the maximum tolerated dose / recommended dose for a particular treatment arm, dose expansion will assess the anti-tumor activity and further assess the safety, tolerability, and PK/PD of each regimen at the maximum tolerated dose / recommended dose or lower dose.
Bowel cancer is the third most common cancer occurring in the UK. Treatment usually involves surgery, often with chemotherapy or radiotherapy. In some cases radiotherapy can be used instead of surgery, especially if surgery may cause a higher risk of symptoms or a colostomy bag. Currently, the medical team collects information on patients' symptoms before and after treatment by direct questions in a clinic setting. It's recognised that patient-reported symptoms often differ from doctor-documented symptoms. This leads to inaccuracies in doctors' descriptions of the effects of cancer or treatment to patients. Patients told us an accurate description of expected symptoms is important when they are choosing their treatment. Patient-Reported outcomes measures (PROMs) may help us identify what affects the QoL after treatment and develop ways to improve it. The primary aim of the trial is to evaluate whether patients find it acceptable to use electronic data collection to assess their symptoms. Many bowel cancer patients are elderly and they may find electronic data system collection more challenging. The secondary aim is to identify which symptoms impact QoL. This will lead to the development of treatments to manage these symptoms which will be assessed in CITRuS2. All patients diagnosed with bowel cancer are entered into the colorectal database to determine the effectiveness of cancer treatments and outcomes. Participants will electronically answer questionnaires at study entry and during follow up. The questions are related to health and well-being with a holistic approach. The questions will take approximately 45 minutes to answer the first time and then 15 minutes thereafter. Following consent, participants gain access to their clinical details on the database. Then they can use a computer, laptop, tablet or smart phone to access a webpage and answer questions at monthly intervals over a 2 year period. Email reminders will be sent to prompt log on. This may help discover how bowel cancer and its treatment affect patients and their lives. This may help doctors describe the effects of treatment more accurately to future patients. It may also help doctors identify which patients need extra help or support through their treatment. Electronic data may allow patterns to be identified that may not be seen by doctors until a later stage. This may enable earlier treatment resulting in less time with symptoms, which could be physically and economically beneficial.
This is a prospective, Single arm Phase II trial. Patients were eligible to participate when they had histological or cytological confirmed metastatic colorectal adenocarcinoma Non-MSI(microsatellite instability)-high and TMB(tumor mutational burden)-High. Patients had to have received at least a second-line standard therapy, including fluoropyrimidine, oxaliplatin, or irinotecan-based regimens and VEGF(vascular endothelial growth factor) inhibitors and to have disease progression within 3 months after the last administration of the last standard therapy or to have stopped such therapy due to unacceptable toxicities. Pre-treatment with anti-EGFR(epidermal growth factor receptor) were mandatory if RAS(Rat sarcoma virus) wild and left side . Patients who met the eligibility criteria took fruquintinib plus Sintilimab until disease progression, death, unacceptable toxicity, withdrawal of consent by the patient, or decision by the treating physician that discontinuation would be in the patient's best interest. The primary study endpoint was PFS(progression free survival) rate at 6 months.
This trial compares cryoablation combined with stereotactic body radiation therapy to stereotactic body radiation therapy alone to see how well they work in treating patients with pain from cancer that has spread to the bones (bone metastases). Bone is a common site of metastasis in advanced cancer, and bone metastases often result in debilitating cancer-related pain. The current standard of care to treat painful bone metastases is radiation therapy alone. However, many patients do not get adequate pain relief from radiation therapy alone. Another type of therapy that may be used to provide pain relief from bone metastases is cryoablation. Cryoablation is a procedure in which special needles are inserted into the tumor site. These needles grow ice balls at their tips to freeze and kill cancer cells. The goal of this trial is to compare how well cryoablation in combination with radiation therapy works to radiation therapy alone when given to cancer patients to provide pain relief from bone metastases.
An upfront-intensified treatment combining all the three active cytotoxic agents in metastatic colorectal cancer (mCRC) including fluoropyrimidines, oxaliplatin, irinotecan (FOLFOXIRI) plus antiangiogenic blockade with bevacizumab significantly improved survival. No biomarkers are available for predicting sensitivity/resistance to single chemotherapeutic drugs, the simultaneous delivery of all active chemotherapeutic agents might overcome resistance to single drugs. Temozolomide has modest but non-negligible activity (about 10%) in chemo-refractory patients with MGMT methylated mCRC. The response rate to temozolomide-based therapy in pretreated patients is increased to up to 20% when restricting the focus on those with MGMT IHC-negative/MGMT methylated and MSS cancers. Clinical and preclinical synergy has been reported for combination of temozolomide with irinotecan and fluoropyrimidines. Temozolomide could be regarded as a "targeted" chemotherapy for patients with MSS and MGMT silenced tumors. In this subgroup of patients, an intensified triplet upfront regimen including temozolomide, fluoropyrimidines, irinotecan, associated with bevacizumab, could be a novel combination in molecularly super-selected mCRC patients. Moving from this, the investigators designed this open-label, monocentric, phase 1b study evaluating the safety of the combination regimen 5-fluorouracil, leucovorin, irinotecan, temozolomide and bevacizumab in patients with MGMT silenced and MSS mCRC. The study will consist in a dose-escalation assessment of the safety of the treatment in subjects with previously untreated MGMT silenced, MSS mCRC. A 3 + 3 design will be used to assess the maximum tolerated dose (MTD) or maximum tested dose of the combination FLIRT-bevacizumab.
Evidence suggests that the addition of cetuximab or bevacizumab to doublet regimens could improve response rate and resectability rate of liver metastases and survival in colorectal liver metastases (CRLM). Moreover, it is observed that FOLFOXIRI yields higher response and resection rates compared with doublet regimens. However, which is better in conversion therapy of RAS/BRAF wild-type initially unresectable CRLM, FOLFOXIRI plus cetuximab or bevacizumab, remains unknown. In this study, RAS/BRAF wild-type colorectal cancer patients with initially unresectable liver-only metastases, as prospectively confirmed by a local multidisciplinary team (MDT) according to predefined criteria, will be randomised between modified FOLFOXIRI (mFOLFOXIRI) plus cetuximab and mFOLFOXIRI plus bevacizumab. Patient imaging will be reviewed for resectability by MDT, consisting of at least one radiologist and three liver surgeons every assessment. MDT review will be performed prior to randomization as well as during treatment, as described in the protocol.
Colorectal cancer screening program has been proven to reduce colorectal cancer (CRC) mortality and is cost-effective. It has been adopted by most countries in the world, and colonoscopy is regarded as the most accurate test for detecting colorectal neoplasm. After screenees underwent colonoscopy, most endoscopists do not routinely explain the preliminary optical diagnosis to the subjects before they going home, which may cause unnecessary anxiety and may reduce the quality of life of the subjects before acquiring the final results. In recent years, endoscopic optical diagnostic technology has been validated by meta-analysis studies as an excellent tool to predict the histology of colorectal polyps and to differentiate the invasion depth of colorectal cancer. The real time feature of endoscopic optical diagnosis allows endoscopists to explain the preliminary results confidently to the subjects immediately after colonoscopy, which is expected to reduce the anxiety of the subjects before they acquired the final results and improve their quality of life. We designed a randomized controlled trial to validate whether real-time endoscopic optical diagnosis could decrease the anxiety burden and improve the quality of life for colorectal-cancer screenees after colonoscopy.
