Filter by:Colorectal cancer (CRC) is the second most common cancer in Malaysia. Diagnosing CRC at early stage is crucial to reduce their mortality risk. To achieve this aim, CRC screening promotion intervention is deemed necessary.
Immunonutrition (IN) appears to reduce infective complications and in-hospital length of stay (LOS) after gastrointestinal surgery. More specifically, it seems to be beneficial also in colorectal cancer surgery. Potential benefits of combining preoperative IN (PIN) with protocols of enhanced recovery after surgery (ERAS) in reducing LOS in laparoscopic surgery are yet to be determined.
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.
Bevacizumab combined with fluorouracil-based chemotherapy is the first-line standard treatment for patients with metastatic colorectal cancer (mCRC). However, some research show that the long-term survival benefit of patients in real world data is inferior to clinical trial. The reason may be related to the difference in follow-up strategy of patients in the real world. Patient-Reported Outcomes (PROs) are a kind of outcome indicators that directly measure and evaluate the disease and its consequences based on how the patient feels about his own health. In advanced cancer, quality of life (QoL) is a major treatment goal. And the electronic patient report outcome (ePRO) has become an effective method to capture the symptoms of patients, which can improve the quality of life and physical and mental health of patients. In order to observe whether ePRO can bring clinical benefits to patients with metastatic colorectal cancer, this study aimed to compare the effects of ePRO and routine follow-up on the quality of life and prognosis of patients with unresectable metastatic colorectal cancer who received first-line bevacizumab combined with chemotherapy. This is an open label, multicenter, randomized controlled prospective study of first-line bevacizumab combined with chemotherapy in patients with unretractable metastatic colorectal cancer.The aim of this study was to assess the impact of ePRO on quality of life and survival outcomes compared with routine follow-up.The study intends to start in February 2021 and end in June 2024.Patients were recruited for 12 months and followed up for 24 months.The study included a screening period (28 days before first-line treatment to 1 day before treatment) and an observation period (from the beginning of treatment to the end of the study).Day 1 (baseline) was defined as the first day of first-line bevacizumab combined with chemotherapy.About 338 patients will be enrolled in the study in China, and enrolled patients will be randomly assigned to one of the following two groups in a 1:1 ratio.
Limited agents are optional after standard first and second line treatment for mCRC. Only Regorafenib and Fruquintinib are approved in China. PFS of these targeted drugs are not very long. Pemetrexed has shown significant efficacy in advanced lung cancer regarding PFS and OS with controllable toxicity. TAS-102 has been used in colorectal cancer with promising outcomes. Bevacizumab is also an important monoclonal antibody which could make benefits in treated patients. This study is aimed to explore the efficacy, safety in advanced colorectal cancer failed to standard therapy in Chinese population.
The rate of screening for colorectal cancer (CRC) in the U.S. remains low (under 65%), meaning that thousands of people die of colorectal cancer unnecessarily. Colorectal cancer screening tests range from more invasive and very sensitive for polyps and cancer (colonoscopy) to less invasive and less sensitive (e.g., fecal immunochemical testing (FIT)). Screening rates go up when patients consider all these tests, not just colonoscopy. Informing patients about their options for CRC screening could produce higher quality decisions, improve the match between patient preferences and tests performed, and increase uptake of CRC screening. Decision aids (DAs) are a promising tool for accomplishing this goal. Also, precision CRC prevention - providing information about an individual's specific risk for CRC - has great promise to increase uptake and improve decision making. Unfortunately, the COVID-19 pandemic is causing severe challenges to providing CRC screening and other prevention services. Health systems are trying to adapt, but these efforts have only begun and are poorly understood. Moreover, patient perceptions of disease risk and risk from COVID-19 are unknown.
Precision prevention holds great promise for colorectal cancer (CRC) screening but has not been adequately explored. A patient's chance of having an advanced colorectal neoplasm (ACN), i.e. a cancer or precancerous polyp in the colon, significantly affects the comparative effectiveness of approved tests. Giving patients a decision aid with information about their risk for ACN, and giving their providers similar information, could help patients and providers decide if colonoscopy or a non-invasive test (such as the fecal immunochemical test) is more appropriate. This could improve decision making and increase uptake of CRC screening, which are the investigative team's long-term goals.
