Filter by:This study expands on protocol (NCT01908504"PET adaptive RT") designed to evaluate the utility of adaptive PET-CT planning for radiation therapy (RT). Radiation therapy is used in many malignant diseases as a curative treatment modality. However, critical normal tissue is often in close approximation to disease, and portions of such tissue must receive high doses of radiation for appropriate treatment. Positron Emission Tomography (PET) adapted radiation therapy, as defined in the current protocol, may allow for a means of determining the eventual response to therapy, at a time point when adaptation of treatment plan may be possible to improve outcomes. This protocol will build upon the findings the previous protocol (NCT01908504 "PET adaptive RT") that evaluated the utility of intra-treatment PET imaging in multiple types of cancers. The current focus will be more specific to certain types of gastrointestinal and gynecologic cancers treated with RT, identified from the prior study to warrant further research.
The clinical trail of electroacupuncture combined with oxaliplatin regimen on gastrointestinal carcinoma.This trail is randomized controled.Patients are diagnosed gastrointestinal cancer based on pathology or cell biology.They are randomized into 2 groups:both groups receive Oxaliplatin regimen.The treatment group receives electroacupuncture in addition to the chemotherapy.The control group only receive the same chemotherapy with the treatment group.Both group have the same adjuvant therapy.
The primary purpose of this study is to determine the non-inferiority of overall survival FOLFIRI with or without Bevacizumab compared with Irinotecan (CPT-11) with or without Bevacizumab as Second-line therapy in Patient with Metastatic Colorectal Cancer.
To assess the effectiveness of close and intense monitoring on nutritional status of gastrointestinal cancer patients during chemoradiotherapy (CRT), 500 CRT patients diagnosed with gastrointestinal system are going to be recruited into this prospective study. Patient-generated subjective global assessment (PG-SGA) scale and nutrition risk screening (NRS-2002) are used for nutritional assessment at the beginning and the end of CRT; Beside the nutritional parameters, Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) and gastric cancer module (QLQ-STO22) are used to measure quality of life in patients with gastric cancer while EORTC QLQ-C30 and Colorectal Cancer-Specific Quality of Life Questionnaire (QLQ-CR38) give assessment in colorectal cancer. The acute and late radiation toxicities were evaluated based on Conmon terminology criteria (CTC V3.0) and the toxicity criteria of RTOG/EORTC, respectively. Follow-ups every 3-6 months until three years after chemoradiotherapy are involved. Response Evaluation Criteria in Solid Tumors (RECIST) guidelines are used for response assessment. The primary endpoints are 3-year local control, disease-free survival, distant metastasis and overall survival rate.
Bevacizumab, as an antibody of vascular endothelial generated factor (VEGF), combined with the fluorouracil-based chemotherapy regimens for metastatic colorectal cancer, has become the classical first-line treatment. However, vast majority of patients eventually will suffer progression disease. The second-line treatment includes replacing chemotherapy regimens whistle continuing bevacizumab or other anti-VEGF antibodies, such as Aflibercept and Ramucirumab. Apatinib is a small molecule tyrosine kinase inhibitor (TKI), which can highly selectively bind to and strongly block VEGF receptor 2 (VEGFR - 2), also potently suppress the activities of Ret, c-kit and c-src, resulting in reduced cell migration, proliferation, and tumor microvascular density mediated by VEGF .There are already robust data showing that antibodies aimed at blocking VEGF signaling pathways combined with chemotherapy to treat advanced colorectal cancer is superior as compared to chemotherapy alone. Thus, we hypothesize that the effect of using the second-line chemotherapy regimens combined with apatinib may be superior to those combined with bevacizumab. In this study,the patients who have progressed following or on first-line oxaliplatin and 5-FU combined with bevacizumab are randomised into two arms. Patients in the experimental arm receive second-line FOLFIRI combined with apatinib and those in the control arm receive second-line FOLFIRI combined with bevacizumab. To compare the efficacy and safety of the two arms, progression-free survival(PFS) is the primary end point.If apatinib is superior to bevacizumab in the second-line setting,it is one possible option of anti-angiogenic therapy in combination with second-line FOLFIRI for treatment of advanced colorectal cancer.
Radiofrequency ablation has been used for treatment of solid neoplasms of the liver, lung, kidney and adrenal. Recently, EUS-guided RFA has become available and the device allows EUS-guided treatment of solid abdominal neoplasms. The procedure has been shown to be feasible in the porcine pancreas and was used to treat small groups of patients that are not suitable for surgery suffering from pancreatic cancers. The aim of the current study is to perform a multi-center prospective study on EUS-guided radiofrequency ablation (RFA) of solid abdominal neoplasms. The hypothesis is that EUS-guided RFA is safe, feasible and effective for treating solid abdominal neoplasms.
An observational study of a prospective, analytical, monocentric cohort which does not modify the patient care because the phenotyping of the dihydropyrimidine déshydrogénase DPD (lymphocyte activity) is already carried out in routine hospital. The analysis will be based on clinical, radiological and biological criteria.
Background: A new cancer therapy involves taking white blood cells from a person, growing them in the lab, genetically modifying them, then giving them back to the person. This therapy is called gene transfer using anti-KRAS G12V mTCR cells. Objective: To see if anti-KRAS G12 V mTCR cells are safe and can shrink tumors. Eligibility: Adults at least 18 years old with cancer that has the KRAS G12V molecule on the surface of tumors. Design: In another protocol, participants will: Be screened Have cells harvested and grown Have leukapheresis In this protocol, participants will have the procedures below. Participants will be admitted to the hospital. Over 5 days, participants will get 2 chemotherapy medicines as an infusion via catheter in the upper chest. A few days later, participants will get the anti-KRAS G12V mTCR cells via catheter. For up to 3 days, participants will get a drug to make the cells active. A day after getting the cells, participants will get a drug to increase their white blood cell count. This will be a shot or injection under the skin. Participants will recover in the hospital for 1-2 weeks. They will have lab and blood tests. Participants will take an antibiotic for at least 6 months. Participants will have visits every few months for 2 years, and then as determined by their doctor. Visits will be 1-2 days. They will include lab tests, imaging studies, and physical exam. Some visits may include leukapheresis or blood drawn. Participants will have blood collected over several years.
Through exploring the specific genetic mutations in the upper gastrointestinal tract tumors with a family history and specific clinical pathological types，we establish a complete family and follow-up system，in order to improve the screening criteria of Chinese hereditary upper gastrointestinal tumors and carry on primary prevention of disease.
