Active clinical trials for "Adenocarcinoma"

Treatment for locally-advanced rectal adenocarcinoma includes preoperative radiochemotherapy before surgery with total mesorectal excision in order to reduce tumor infiltration, facilitate oncologic surgery and improve survival. About fifty percent of these patients are good responders i.e. their tumor infiltration reduces in the rectal wall and regional lymph nodes in order to be graded ypT0 to T2 N0 after pathologic assessment (so called downstaging). At the opposite, bad responders (ypT3-4 and/or N+) are not sensitive to standard preoperative radiochemotherapy, and their survival is poor than good responders. Until now, response to preoperative radiochemotherapy cannot be anticipated before pathological assessment of surgical specimen. Proteomic analysis of sera from good and bad responders to preoperative radiochemotherapy could allow identification of early biomarkers of tumor response, and subsequently adaptation of treatment to increase preoperative treatment efficiency and survival in most patients.

Over the last 10 years, technological advances in molecular biology enabled a more accurate genomic characterization of tumors. For each tumor location, this led to the identification of subgroups with similar molecular characteristics. This identification allowed the development of targeted therapies and thus to improve the patient prognosis. This molecular characterization has also revealed the tumor heterogeneity. It may be the cause of treatment resistance and therefore of relapses. Additionally, tumor cells are in constant dialogue with their microenvironment composed of different immune or non immune cells. This microenvironment is now targeted in cancer treatment. To date, there are few studies that combine a deep genomic characterization of both tumor and tumor microenvironment of the patient. Combining the two types of studies on the same tumor should help to define new therapeutic targets and should allow a combination of targeted and immunomodulatory therapies. To this end, our project is to conduct an exhaustive integrated exploratory analysis at genomic, transcriptomic and immunological levels of 3 tumor types (in colon, kidney and liver cancer).

This project aims to do a small sample exploratory study, to predict EGFR-TKI targeted therapy gefitinib' s efficacy in late stage lung adenocarcinoma patients (phase IIIB or IV), who have negative tissue EGFR gene mutation, positive plasma free nucleic acid EGFR gene.

The aim of this study is the characterization from epidemiological, radiomics and molecular point of view of lung metastasis of patients at beginning affected by pancreatic adenocarcinoma (PDAC), which after the resection of primitive tumor have met with initial recurrence of the disease exclusively at the lung level.

The Siewert classification of oesophageal cancer is the standard approach in anatomically subdividing cancer of the lower oesohagus.

The study of sarcopenia is a subject that is the subject of numerous research and publications, particularly because of its link with a poor prognosis for many cancers. In an article published by the digestive surgery team, the role of feeding jejunostomy has been demonstrated: it allowed more patients to reach the 2nd stage of surgery and a better tolerance of chemotherapy. Investigators wanted to study retrospectively the impact of feeding jejunostomy on radiological sarcopenia. Is the positive effect of jejunostomy in gastric cancers associated with a decrease in sarcopenia?

The aim of this study is to analyse the effectiveness and security in the prevention of anastomotic leakage by protecting the ileocolic anastomosis with a reabsorbable NHS-PEG collagen patch.

The purpose of this study is to assess lymph node metastasis rate, distant metastasis rate, disease-specific mortality, and overall mortality in patients with Barrett's related T1b and high risk T1a esophageal adenocarcinoma (EAC) who underwent a diagnostic endoscopic resection.

This is a retrospective study comparing neoadjuvent short course radiotherapy to conventional chemoradiation in locally advanced cancer rectum and the effect of both regimens in overall survival and disease free survival

The investigators performed a randomized, double-blind controlled, prospective study method on observation of Traditional Chinese Medicine combined with targeted therapy to prolong the efficacy of long-term survival of advanced pulmonary Adenocarcinoma patients.The investigators plan to involve 404 cases for observation in 3 years (202 cases for each group), expecting that integrated TCM combined with targeted therapy has a better efficacy on prolonging progression-free survival time, overall survival, improving QOL of patients than that of targeted therapy.
