Active clinical trials for "Neoplasms"

The purpose of this study is to clarify the relationship bone marrow-derived cells and the formation of the tumors, and the role of these cells in regeneration of epithelial cells in the gastrointestinal tract.

Can MRI be used to stage ovarian cancer?

The main objective is to identify obstacles and elements facilitating the implementation of a tracking device Broncho Pulmonary Cancer during the course of care. The secondary objective is to assess patient knowledge and information received on their previous occupational exposure during their professional activity. This is a prospective multicenter study of qualitative methodology through in-depth interviews conducted with patients treated at ICLN and CHU Saint-Etienne

Prospective, observational study aimed to investigate the specific hemostatic alterations in patients undergoing glial tumor resection.

This study will investigate the prevalence of chronic obstructive pulmonary disease (COPD) in patients who are newly diagnosed with lung cancer and compare it to the prevalence of COPD in controls recruited from a smoking cessation clinic.

objectives: To development of NCC-PCI-Operative Template (NPOT) for the objective description of perioperative tumor burden and surgical approaches in the management of ovarian cancer, tubal cancer, and primary peritoneal cancer

Rationale: With 1.6 million new cases diagnosed each year and 1.3 million deaths, lung cancer is the leading cancer-related death worldwide and it represents a pressing health issue. Patients with lung cancer are more likely to experience cachexia, a severe debilitating disorder causing fatigue, weight loss, muscle wasting and associated with reduced physical function, increased chemotherapy toxicity and reduced survival. This syndrome occurring in about 80% of advanced cancer patients is the direct cause of death in about 20% of cases. However, despite the importance of cachexia in lung cancer, its mechanisms ans its relation with muscle function and effort tolerance are still unknown. Aim: To explore muscle function, signaling pathways and its relationship to impaired functional capacity of patients with non-small-cell lung cancer(NSCLC); depending of whether they have cachexic state at diagnosis. Methods: This study will be conducted at the Institut universitaire de cardiologie et de pneumologie de Québec. 56 patients newly diagnosed of NSCLC will be recruited and separated whether or not they have a cachexic state. The evaluation will need two visits separated by 5 days. During the evaluation the following tests will be done: Anthropometric measures Level of daily physical activity Pulmonary function test Maximal incremental cardiopulmonary exercise test on ergocycle Endurance test on ergocycle Muscle function tests Magnetic stimulation Quadriceps biopsy

Non-Hodgkin lymphoma (NHL) is one of the more frequent cancers in the western world with approx. 800 new cases annually in Denmark. Diffuse large B-cell lymphoma (DLBCL) in Denmark accounts for almost 40% of newly diagnosed NHL cases. Treatment with the combination of chemotherapy and monoclonal antibodies has significantly improved prognosis over the past decade, but a large proportion of patients with DLBCL will continue to relapse with our current treatment options. Therefore, there is a need for reliable methods for detection of treatment response as early as possible in the treatment course in order to identify patients who respond poorly to standard treatment and potentially would benefit from a change in treatment strategy. This has still not been established, but a valid early marker is required in order to allow randomized trials of treatment stratified by early response. One of the most promising applications of PET is the metabolic assessment of the early response of cancer treatment. This study is a national prospective multicenter study emanating from the Danish Lymphoma Group (DLG). Patients are scanned after each of the early 4 cycles of chemo therapy. The aim is to establish the correct timing of response evaluation. Additionally, the investigators wish to investigate the optimal qualitative and quantitative method of response assessment in order to predict post-therapeutic remission and long-term prognosis.This study will contribute to interim-PET being implemented in the most optimal way in daily clinical practice.

Concurrent chemotherapy with external beam radiotherapy is the standard treatment of bulky or locally advanced cervical cancer, gastric cancer and rectal cancer.Despite excellent therapeutic results, acute hematologic toxicity (HT) is common with this regimen. Previous studies have founded acute HT was significantly associated the volume of pelvic (PBM) and lumbosacral bone marrow (LSBM) receiving 10 and 20 Gy radiation (RT). Therefore, reducing the volume of BM receiving low-dose RT might prevent HT. More than one-half of the body's bone marrow (BM) is located in the PBM, LSBM and proximal, where is just in the low dose of RT in patients with gastric, rectal and cervical cancer. Previous study have demonstrated highly conformal IMRT treatment plans reduced the volume of PBM irradiated resulting in less HT. We have since assumed that even better BM sparing is possible when the BM is entered as a separate constraint in the planning process. However, it is well known that hematopoietically active (red) BM is poorly visualized with computed tomography (CT). Consequently, the entire contents of the medullary canals must be entered as BM. Yet, a considerable portion of the medullary canal is comprised of inactive (yellow) marrow, which is composed primarily of fat. Contouring the entire medullary canals on CT thus overestimates the volume of active BM, unnecessarily constraining the IMRT plan. An alternative approach is the incorporation of functional BM imaging into the treatment planning process. One economical and efficiency approach involves the use of T1-weighted magnetic resonance (MR) images. Therefore, we designed this study to test whether a separate constraint of active BM identified by MR could reduce acute HT in course of concurrent chemoradiotherapy for patients with gastric and rectal cancer.

The goal of this study is assess the quality of life of advanced non-small cell lung cancer (NSCLC) patients who are undergoing first-line chemotherapy, analyze the current status and tendency of quality of life (QOL). The method is to use the Functional Assessment of Cancer Therapy-Lung (FACT-L) scales, assess the quality of life before the chemotherapy, after 1st cycle of chemotherapy and after 2nd cycle. After 3 time-points, investigators analyze all the subscales and constructs of FACT-L. The assumption is the quality of life will be better after 2 cycle of chemotherapy.
