Filter by:Background: The current screening techniques for colorectal cancer include colonoscopy, fecal occult blood, and high-risk factor questionnaires. However, the colorectal cancer screening technology that has been widely used at present cannot take into account sensitivity and specificity, and the tumor detection rate is low. The purpose of research: 1. Build a new type of population colorectal cancer precision screening technology program; 2. Improve the detection rate of colorectal cancer in the population by new methods (compared with the existing domestic advanced technology) by ≥20%, and improve the specificity of colorectal cancer screening by ≥15% without significantly reducing the sensitivity.
This is a prospective, single-arm, open-label, non-interventional, multicenter, post-marketing surveillance to assess the safety and effectiveness of Zirabev(Bevacizumab biosimilar) in domestic patients with non-small cell lung cancer, metastatic colorectal cancer, metastatic breast cancer, advanced or metastatic kidney cancer, cervical cancer, epithelial ovarian cancer, fallopian tube cancer, primary peritoneal cancer or glioblastoma multiforme.
Currently, comprehensive treatments for liver metastasis/pulmonary metastasis that cannot reach NED include systemic chemotherapy, interventional chemotherapy, molecular targeted therapy, immunotherapy, and local treatments (ablation therapy, radiation therapy, etc.) for liver metastases. Combination therapy model of local ablation, systemic chemotherapy, and anti-PD -1 monoclonal antibody hopefully can prolong patient survival. This trial will evaluate the effectiveness and safety of carrelizumab combined with microwave ablation and chemotherapy in the treatment of colorectal cancer liver metastasis/pulmonary metastasis
It is important for patients treated with anti-EGFR therapies to get access to cosmetic options to preserve their skin condition during treatment. Anti-EGFR therapies are known to fragilize epidermis and to provoke rashes; which often lead to treatment discontinuation. The aim of this study is to demonstrate that the Onco-Rash cream is able to preserve skin condition without side effects. Decreasing skin toxicity is expected to improve patients' life and facilitate treatment follow-up.
In a cluster-randomized study compare if feedback from two computerized feedback systems doing a colonoscopy (CoPS and CoRS) can improve the adenoma detection rate and decrease patient discomfort.
This is a randomised, multicentre observational study in patients suffering from RAS mutant mCRC with primarily unresectable metastases, who are planned to be treated with FOLFOXIRI and bevacizumab or who have already received ≤ four cycles FOLFOXIRI and bevacizumab as first-line treatment of metastatic disease. The patients are randomised in a 1:1 ratio to compare the rate of patients in whom secondary interventions (e.g. resection, ablation) are performed in curative intent when secondary intervention options are assessed by a multidisciplinary centralized tumour board (Arm A) versus when secondary intervention options are not assessed by a multidisciplinary centralized tumour board (Arm B). All patients evaluated in the study will receive chemotherapy with FOLFOXIRI plus bevacizumab. After this induction/conversion therapy, imaging (CT or MRI) will be performed to evaluate resectability. In Arm A, a multidisciplinary, centralized tumour board will assess options of secondary intervention to be performed in the context of a generally curative treatment approach. If there are secondary intervention options according to the judgement of the centralized tumour board, they will be listed in their respective sequence and the assessment will be communicated to the participating physician or his/her deputy at the study center. The decision, whether or not any secondary intervention is performed as recommended by the centralized tumour board as well as the kind of interventional procedures is up to the discretion of the treating physicians and surgeons of each patient. Any secondary intervention is recorded. Evaluating the primary endpoint, the first interventions performed in one organ (e.g. liver) are rated when performed in a generally curative context (e.g. even in the presence of lung metastases that need to be approached in a further intervention). In Arm B, no centralized tumour board will be integrated in to clinical decision making and patients will be treated according to institutional guidelines. The number of treatment cycles with FOLFOXIRI and bevacizumab will be according to local clinical routine and medical guidelines, recommended are 8 to 12 cycles FOLFOXIRI in combination with bevacizumab, followed by a maintenance therapy with fluoropyrimidine (FP) plus bevacizumab until progression.
This study is a prospective, randomized, comparative clinical trial conducted by Wuhan Union Hospital and aim to compare the therapeutic effects of Mitomycin and Lobaplatin in the treatment of advanced colorectal cancer patients with radical surgery combined with hyperthermic intraperitoneal chemotherapy
Nodal staging holds both important prognostic and predictive value at colorectal cancer. Regional lymph nodes are located close to the primary tumor in the mesocolon / mesorectum. Current pathology and oncology standards require a separate examination of at least 12 lymph nodes each case to fulfill staging "accuracy" criteria. In order to reach this number of lymph nodes, a precise surgical technique (total mesorectal excision or complete mesocolic excision), as well as a thorough pathological specimen work-up is needed. The aim of the study is to investigate, if ex vivo intra-arterial methylene blue injection by the surgeon can help improving nodal harvesting effectivity of the pathologist, hence leading to a better staging and hopefully even to a better outcome in the long run. In 2014-2015 two surgical centers randomised resected colorectal specimens in 1:1 ratio to methylene-blue injection arm and control (no injection) arm in a total of 200 consecutive cases. Both pathologic and oncologic treatment were led regardless of the injection, reports were just routinely saved in the routine medical documentation. This retrospective study is designed to recall patient-related, surgery-related factors, as well as pathology reports including nodal staging from the medical databases. The investigators aim to find correlation between methylene blue "staining" and lymph node yield. In addition, the investigators plan to crossmatch methylene blue injection, as a process, with long term survival of the patients.
In Argentina, there is vast experience in qualitative iFOBT population screening that is part of the CRC Prevention and Early Detection National Program. The screening's cut-off point is at 50 ng/mL buffer. Its positivity rate for 2019 has been an average of 26.15%, over the double of the one reported in the international literature (7.5-11%) for this cut-off point (1). There are no studies that assess such technology and suggest an appropriate cut-off point for this population. The goal of this study is to assess the diagnostic performance of the qualitative iFOBT used in the present and the quantitative iFOBT with various cut-off points for advanced neoplastic wound screening (colorectal cancer and advanced adenoma) in an Argentine patient cohort.
This study aimis at detecting the genomic changes of ctDNA in patients of RAS and BRAF wild-type mCRC, who failed after first line treatment containing cetuximab. According to the results of ctDNA detection, individualized second-line targeted therapy strategies were developed to explore the disease control rate and prognostic significance of ctDNA-guided treatment for metastatic colorectal cancer.
