Filter by:This study aims to develop a smartphone-based psychosocial intervention for patients with colorectal cancer and their family caregivers and to improve patients' confidence in self-care, psychological well-being, social support, quality of life, and satisfaction with care, as well as caregivers' burden, psychological well-being, and quality of life. The study also aims to explore patients' and their caregivers' perceptions of the intervention and routine care. A multi-centre two-arm experimental study design is used in this study. A total of 100 patient-caregiver dyads will be recruited and randomly allocated to either the control group (receiving routine care alone) or the intervention group (receiving routine care plus the psychosocial intervention). After completed the study, 15 patient-caregiver dyads will be invited for interviews to explore their perceptions on the intervention and/or routine care. This study will generate evidence on the effectiveness of the easily accessible and sustainable smartphone-based psychosocial intervention.
Bifico (also known as "bifidobacterium trifidum live powder") is a probiotic preparation that has been marketed and widely used in China. The number of live bacteria of lactobacillus acidophilus and bifidobacterium per gram should not be less than 1.0×107CFU. At present, it is mainly used for diarrhea and abdominal distension caused by intestinal flora imbalance. It can also be used for treating mild to moderate acute diarrhea and chronic diarrhea. Lactobacillus acidophilus and bifidobacteria have been fully proved in basic studies to improve gut microbiological environment and inhibit colorectal cancer. A recent paper published by Nature Biomedical Engineering reported that chemotherapy can effectively enhance the efficacy of colon cancer by regulating intestinal flora. Based on the above evidence, we propose that the current standard chemotherapy plus targeted therapy regimen combined with Bifico can exert a more powerful synergistic anticancer effect. To sum up, this study put forward innovative joint regulating intestinal flora environment with standard chemotherapy and target therapy of new concept and mode, to assess Bifico combined with standard chemotherapy plus targeted therapy compared to standard chemotherapy plus targeted therapy for efficacy and safety of metastatic colorectal cancer, combined with the intestinal flora, probiotics patient blood DNA analysis, etc. New technology, explore flora index correlation with the prognosis of patients' immune system function, and its potential as a predictive marker. It is worth noting that this study will closely combine the current most advanced intestinal flora 16S microbial polymorphism detection and single-cell sequencing technology, so as to truly achieve accurate and individualized treatment, evaluation and prognosis prediction.
One of the major barriers to CRC screening participation is a negative perception of colonoscopy as a painful and unpleasant procedure. Previously, by monitoring patient-reported outcomes as one of the colonoscopy quality performance measures, the investigators identified the endoscopist as the single, most important risk factor for painful colonoscopy. Therefore, the investigators propose a randomized controlled trial to analyse the effectiveness of directed training on the endoscopists painful colonoscopy rate. The study will be conducted in two phases: endoscopist categorization and design of training (I) and randomized controlled trial evaluating training effectiveness (II). Phase I will include endoscopists from Polish Colonoscopy Screening Programme (PCSP) willing to participate. Volunteers will be divided into underperformers, average performers and overperformers, based on their painful colonoscopy rate (obtained from PCSP database records) and will be invited to take part in the initial workshop focused on pain reduction during colonoscopy (conducted in a similar fashion to Train Colonoscopy Leaders (TCL) workshop, aiming at ADR improvement). On the basis of the differences in performance between over- and underperformers, categories of importance, target scores and a questionnaire for the assessment of factors for improvement will be developed. In Phase II, endoscopists from PCSP screening centres previously categorized as underperformers and average performers will be randomized in 1:1 ratio either to control (no intervention) or intervention arm. The subjects in the control arm will not be trained or informed about study participation. The endoscopists assigned to the intervention arm will be invited to take part in one training session designed in Phase I of the study (according to the evaluation questionnaire from Phase I). Willing overperformers will be asked to participate in the training as teachers. The training session will be divided into two parts: theoretical - presentation of research on painless colonoscopy - and practical - colonoscopy performance with commentary. Subjects matched 1:1 with trainers will take part in such a session, supervised by the study coordinator. Each endoscopist who underwent training in the second phase of the study will be sent a written, customized feedback on changes after the intervention and information about factors to improve (as per evaluation questionnaire from Phase I of the study). All endoscopists enrolled into Phase II will be followed through PCSP database for the endpoint of painful colonoscopy rate; the intervention arm will be compared with the control group at 6 and 12 months after feedback in order to investigate whether the adjusted painful colonoscopy rate improved as a result of the intervention.
Part I of this study is designed to identify the recommended phase 2 dose (RP2D) of the combination regimen of LY3200882/capecitabine as second line treatment in patients with 5-FU or capecitabine resistant CRC. Part II is designed to obtain proof of principle of the LY3200882 plus capecitabine combination in patients with chemo-resistant CRC. The combination of LY3200882 plus capecitabine will be given as second line therapy in the phase II part of this study. Patients with chemotherapy resistant activated TGF-β signature-like tumors will have received a fluoropyrimidine (5FU or capecitabine) in the first line of chemotherapy, usually combined with oxaliplatin and, depending upon local hospital preferences or national guidelines, also bevacizumab, or cetuximab/panitumumab if the tumor is KRAS wild type. Addition of LY3200882 to capecitabine should thus result in reversal of unresponsiveness, which is the first step in exploring this concept in the clinic. Capecitabine can be used as single agent in advanced CRC and is thus attractive for this study concept. If proof of principle is achieved also other tumor types can be explored with this genetic makeup, such as non-small cell lung cancer (NSCLC) in second line of treatment after platinum doublet therapy in first line, usually cisplatin/carboplatin-pemetrexed in non-squamous and cisplatin/carboplatin-gemcitabine or cisplatin/carboplatin-paclitaxel in squamous type NSCLC.

Peritoneal carcinomatosis (PC), a tumoral tumor of the peritoneum, is a frequent metastatic localization of colorectal cancer (CRC, 13%). Long regarded as a palliative situation, its management has progressed significantly with a curative treatment based on a complete cytoreduction surgery coupled with intraperitoneal hyperthermic chemotherapy. However current screening tools, tumor markers (ACE, CA19-9, CA125) and abdominopelvic CT scan are insufficient, to diagnose CP early. A non-invasive biomarker, more sensitive and more specific than currently available tumor markers, would be a major advance in oncology. Microparticles (MPs), vesicles from extracellular membrane budding in response to cell activation or apoptosis of different cell types, have been described as implicated in tumor progression, procoagulant activity associated with cancer, and initiation of metastatic niches. A specific microparticulate (microparticulosome) signature has been reported in patients with CRC, particularly in the presence of a thromboembolic event. However, there is currently no data on PMs and their involvement in CP. In addition, CP and surgery coupled with hyperthermic intraperitoneal chemotherapy are major risk factors for thromboembolic complications. The characterization of prothrombotic PMs is therefore essential to predict such event. The main objective of this project is to characterize the microparticulate signature of CP of colorectal origin and to compare it with that of CP without CP. The secondary objectives are to compare the microparticulate signature obtained on peripheral venous samples and intraoperative tumor samples, evaluate the evolution of the microparticulate signature between the beginning and the end of the intervention, then correlate the peripheral signature to the oncological follow-up of the patients with CP and the occurrence of a thromboembolic event.
