Active clinical trials for "Adenocarcinoma"

This study aimed to detect cell free DNA (cfDNA) in the cerebrospinal fluid and plasma, and to determine whether cfDNA can be used for concomitant diagnosis to improve the treatment efficacy and prognosis of patients with brain (meningeal) metastasis by monitoring tumor-related genetic mutations in cfDNA in the plasma and cerebrospinal fluid.

This research intend to collect the information of gastric cancer patients who received preoperative neoadjuvant chemotherapy and radical gastric ectomy at Department of Gastrointestinal Surgery, West China Hospital, Sichuan University. Base on The degree of edema, intraoperative effusion, fibrosis of connecting tissues, the investigators aim to constitute the core parameters of the tissue response grading system following neoadjuvant chemotherapy, and explore the mutual effect among the tissue response grading system, tumor regression response and long-term survival outcome of tumor patients.

There are several types of early pre-cancerous lesions found in the pancreas which have the potential to develop into pancreatic cancer. Although different patients' pancreatic cancers or pre-cancerous pancreatic lesions have many similarities we believe that subtle differences can affect how they behave and therefore influence individual patient outcomes. Many factors may account for the differences seen in pancreatic lesion behaviour, for example molecular and genetic differences (the DNA and RNA present which control how a cell grows and divides), differences in how the immune system responds to the lesion, differences in the environment immediately around the lesion in the pancreas, known as the tumour microenvironment and differences in the micro-organisms which colonize a particular patient, known as their microbiota . This project studies the molecular makeup of pancreatic lesions and their microenvironment at various stages (from pre-cancerous lesions all the way through to more advanced disease) to see if we can use this information to divide patients into different groups whose lesions may behave in similar ways. We will be trying to find out if there are molecular reasons why some patients respond to particular treatments when others do not, why some patients experience more toxicity with particular treatments and why some patients' disease behaves particularly aggressively when other patients' disease does not. We will also be investigating the particular micro-organisms colonizing individual patients to see if these impact a patient's outcome. Understanding what makes one person's pancreatic lesion behave differently to another's could lead to better treatment, where a personalized therapeutic strategy could be applied for every single patient.

Every year in France, 30.000 deaths are due to lung cancer and 39.500 new cases of this disease are diagnosed (INCa 2014). Patients suffering from locally advanced non-small-cell lung cancer (NSCLC), stage IIIa, usually undergo a multimodality treatment including chemotherapy with platinum compounds before surgery (called neoadjuvant chemotherapy or induction chemotherapy). The reason of this combined modality treatment is the really poor prognosis of patients presenting a disease already spread to lymph nodes (classified N2 when the lymph node under the carina is affected). Up till now, the five-year survival of patients who underwent surgical resection of N2 NSCLC does not exceed 15%

The purpose of this study is to investigate the difference in the success rate of culturing primary cells derived from pancreatic ductal adenocarcinoma specimens of patients which obtained by endoscopic ultrasound-guided fine-needle biopsy wet suction technique and surgery, analyze whether the sensitive chemotherapeutic agents screened by the primary cells cultured from the specimens obtained by the above two methods are consistent, and whether they are consistent with the clinical treatment effect of patients, verify the accuracy of laboratory drug sensitivity results, so as to provide the basis for pancreatic ductal adenocarcinoma patients to choose the source of individual treatment samples.

Study tolerability and toxicity of radiotherapy with or without chemotherapy for operated gastric cancer. Evaluate the efficacy of adjuvant radiotherapy with or without chemotherapy as regarding local control and overall survival.

This is a retrospective study using images acquired routinely for diagnosis of rectal cancer to see if these could be used to predict responses to radiotherapy treatment and if it can, whether the treatment can be optimised to produce better outcome for patients. Using a clinical database, patients who have had neo-adjuvant chemo-radiotherapy will be recruited, their diagnostic images and radiotherapy planning scan will be obtained. By use of imaging registration and clinical information, the question of why some patients respond well to radiotherapy and some don't could be answered.

The study of extended total mesopancreas excision(eTME) for pancreatic head adenocarcinoma is a retrospective multicenter cohort, collecting medical records and follow-up data of patients who underwent radical resection with pancreatic head adenocarcinoma.

The utility of adjuvant chemotherapy in the management of Small Bowel Adenocarcinoma (SBA) remains unproven and awaits the results of a large, global, prospective, phase III, randomised, controlled trial. Across the 830 million population of North America and Europe, there are approximately 3,000 patients with stage I-III SBA every year who would be potentially eligible for such an adjuvant chemotherapy trial. Given the absence of good-quality and evidence-based data, it has been agreed that a trial considering adjuvant chemotherapy versus no chemotherapy was appropriate for patients with stage I-III SBA in whom the oncologist and patient feel that the benefit of adjuvant chemotherapy is uncertain. For those patients with stage I-III SBA who, with their oncologists, feel that the potential benefit of adjuvant chemotherapy is certain (and hence are not willing to accept randomisation to the 'no chemotherapy' arm), a randomisation between single agent fluoropyrimidine versus doublet fluoropyrimidine and oxaliplatin chemotherapy will be offered. Tumour stage will be used as a stratification factor. Those patients who do not consent to be randomised will be offered registration to allow collection of demographic, clinicopathological and survival data, thereby making optimal use of the rare patient population available. In addition, archival Formalin Fixed Paraffin Embedded (FFPE) tissue and contemporaneous venous blood samples will be collected from every registered patient to allow molecular profiling and future translational research. A questionnaire about underlying risk factors (e.g. Crohn's disease, coeliac disease, Lynch syndrome etc) will be completed along with the other collected data on all registered patients.

Mortality due to non small cell lung cancers is the first cause of cancer death in men around the world. Lung adenocarcinoma regularly induces bone metastases responsible for high morbidity and impaired life quality. Overall survival of these patients is poor. Thus the investigators aimed to identify if some bone and metabolic parameters were associated with overall survival. Patients and Methods POUMOS is a prospective cohort of patients suffering from adenocarcinoma lung cancers with a first bone metastasis (stage IV). All patients have a bone biopsy with molecular status characterization of the tumor for EGFR, KRAS, BRAF and ALK. Bone metastasis localizations are obtained by bone scintigraphy or FDG-PET/CT. Whole body composition is obtained by DEXA scan (Hologic®). The investigators assessed also fasting blood levels of bone and metabolic biomarkers. Survival analyses will be performed using a proportional hazard regression model.
