Filter by:The aim of this trial is to evaluate the value of palliative primary tumor resection in colon cancer patients with initially unresectable metastases and a positive response to induction chemotherapy which depends on gene testing. The primary endpoint is to evaluate overall survival.
According to general medical guidelines, adjuvant chemotherapy is used after curative resection of high-risk stage II or III primary colon cancer. However, there exist limitations using clinical trial data acquired from highly selected subjects in a controlled environment. For example, patients aged over 70 years old were in many cases excluded from clinical trials resulting in insufficient data on the efficacy of therapies including oxaliplatin in aged patients, and the source data of the medical guidelines did not fully reflect the conditions of Korean patients. In addition, suggestions are continuously being submitted for existing therapies with modified administration periods and methods with the aim to search for the optimum effect over side effects. Discussions are also held on meta analyses results that imply the need to apply slightly different approaches through small groups of patient and disease factors. As there are more diverse adjuvant therapy protocols that can be applied to post-surgery colon cancer patients, it is necessary to figure out the patterns of adjuvant chemotherapies actually used in Korean medical practices. Also, in order to complement the limitation of external validity of the existing base clinical data, a multifaceted exploratory analysis will be conducted by making follow-up observations on patterns, prognosis results, quality of life, adverse effects, etc. of post-surgery adjuvant chemotherapies actually used in around 30 sites in Korea under the noninterventional observational study conditions.
According to the 2019NCCN guidelines, immunocheckpoint inhibitors are recommended for first-line treatment of metastatic colon cancer patients with high microsatellite instability (msi-h) or mismatched gene deletion (dMMR) who are not suitable for intensive treatment, and for all patients with second-line or above msi-h /dMMR treatment.This study is a single-center, single-arm phase II study of the use of triplezumab (JS001) combined with CAPEOX regimen in the neoadjuvant therapy of msi-h /dMMR for locally advanced colon cancer. The subjects received neoadjuvant therapy with triplezumab (JS001) combined with CAPEOX regimen, with one treatment cycle every 3 weeks and two cycles of surgery followed by pathological evaluation.
The efficiency of the D3 lymph node dissection is still controversial for left colon cancer patients. This study will try find difference in 5-year overall survival between D2 and D3 lymph node dissection. Investigation of the functional and short-term outcomes will clarify safety of the D3 lymph node dissection.
It has been reported that Cryptosporidium parvum, a species of a protozoan frequently isolated from humans and animals, is able to induce digestive adenocarcinoma in a rodent model. Consistently, some epidemiological studies have reported an association with cryptosporidiosis in patients with colorectal adenocarcinoma. However, the correlation between cryptosporidiosis and human digestive cancer remains unclear at this time, and it is not known whether this intracellular parasite, considered an opportunistic agent, is able to induce gastrointestinal malignancies in humans. In order to add new arguments for a probable association between cryptosporidiosis and digestive human cancer, the main aim of this study is to determine prevalence and to identify species of Cryptosporidium among a French digestive cancer population.
VAPOR-C is a randomised study of the impact of IV versus inhaled anaesthesia (propofol versus sevoflurane) and lidocaine versus no lidocaine on duration of disease free survival inpatients with either colorectal or non small cell lung cancer.
This study will gather information on the safety and effectiveness of pembrolizumab, an immunotherapy drug. The purpose of this study is to target early stage colon cancer before it has developed resistance to immunotherapy.
This early phase I trial studies how well heated intra-peritoneal chemotherapy with doxorubicin and cisplatin work for the treatment of abdominal or pelvic tumors that can be removed by surgery (resectable), does not respond to treatment (refractory), or has come back (recurrent). Heated intra-peritoneal chemotherapy is a procedure performed in combination with abdominal surgery for cancer that has spread to the abdomen. It involves the infusion of a heated chemotherapy solution that circulates into the abdominal cavity. Chemotherapy drugs, such as doxorubicin and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Heating a chemotherapy solution and infusing it directly into the abdomen may kill more cells.
The comparison between total laparoscopic and laparoscopic assisted left hemicolon cancer resection underwent to choose a more effective and safe operation.
The human intestine is colonized with a complex microbial community and forms a super organism with the human body. Intestinal microorganisms include more than 1,000 kinds of bacterias, and their flora is very complex and functions are very diverse. The intestinal flora affects the body's nutrition, immunity and metabolism through interaction with the human body and the external environment, and is closely related to multiple systems. When the flora structure and function are changed, it will lead to the occurrence of various diseases or increase the risk of disease. In recent years, the role of intestinal microbes in tumorigenesis and development, as well as the role of diagnosis and treatment have been paid more and more attention. Abnormal intestinal flora can not only promote tumorigenesis, but also affect radiochemotherapy and immunotherapy effects. It is worth noting that the huge impact of the intestinal flora on immunotherapy suggests that immune checkpoint inhibitors can maximize the efficacy by protecting the balance and diversity of the intestinal microecology. Therefore, in this study, quantitative analysis of the diversity and abundance of intestinal, urinary tract flora, and urine components before and after adjuvant chemotherapy in patients with gastric and bowel cancer was performed. The link between treatment efficacy and prognosis.
