Active clinical trials for "Adenocarcinoma"

Optic atrophy type 1(OPA1) is a nuclear dynamin-related GTPase, targeted to the inner mitochondrial membrane, which plays a role in mitochondrial fusion. Mitochondria fusion is associated with process of apoptosis. . OPA1 plays an important role in the mitochondrial bioenergetics and mitochondrial networks. The changes in mitochondrial shape and mitochondrial bioenergetics may be cause of the disease. In this study, we investigate the expression of OPA1 in lung adenocarcinoma (LADC) cells and tissue.

AMP-activated protein kinase (AMPK) is an evolutionally conserved protein kinase that serves as an energy guardian to help cells adapt to various metabolic stress including hypoxia. Because the role of AMPK in cancers has not been fully elucidated, in this study we investigated the expression and activation of AMPK in lung adenocarcinoma (LADC) cells and tissue.

Pancreatic adenocarcinoma will be the 2nd cause of death by cancer in Europe in 2030. Pancreatic adenocarcinoma has poor prognosis with an all-stages combined 5-year survival rate below 8%. Since December 2019, a new coronavirus (Severe Acute Respiratory Syndrome Corona Virus 2, SARS-CoV-2) is responsible of COVID-19 infection with potentially severe respiratory syndrome or even multi-organ failure. An increased risk of severe COVID-19 infection in cancer patients is suggested in several Chinese series. Cancer care structures quickly reorganized to limit high-risk situations (diagnostic procedure, major surgery, cytotoxic poly-chemotherapy) and use alternatives such as on-hold chemotherapy. These reorganizations could be associated with a loss of chance for pancreatic adenocarcinoma.

Intro: Recent studies on colorectal cancer surgery have been focusing on the role of intestinal microbiome on surgical outcomes. Standard perioperative cares, like mechanic bowel preparation (MBP), administration of antibiotics (ABT) and surgery-related stress and injury influence the microbiome composition and possibly induce a shift toward a microbiome dysbiotic state, which predisposes to complicated postoperative course. Microbiome composition changes and enhanced virulence factors may increase the risk of postoperative complications, such as anastomotic leakage (AL), surgical site infection (SSI), and postoperative ileus (PI), which are known to impact on patient's overall survival and cancer recurrence. Objective: The primary objective is to investigate if a significant association might exist between the microbiome composition and the occurrence of postoperative complications at 90 days. Methods: 3 different microbiome samples will be taken from all patients. Two fresh fecal samples for detection of LM and fecal water preparation: a) a day before the surgery before MBP and/or ABT (LM1), b) postoperatively after first bowel movement (LM2). One sample will be taken intra-operatively from the stapled resection lines of circular stapler used for forming a colorectal anastomosis, to detect the MAM and to perform immunohistochemistry staining for detection of HACE1 expression. DNA analysis will be performed for all samples. IHC will be performed for detecting HACE1 expression in the tumor and colorectal anastomosis tissues using anti-HACE1 antibodies. . For proliferation assessment, human colon carcinoma cell lines HT29 will be plated in monolayers and scratched with a single scratch. Monolayers will be incubated for 24 hours with fecal water from patients with surgical complications and matched control patients without complications. Descriptive statistics will be performed to describe the study population. This project aim to describe microbiome composition and its impact on postoperative complications.

Cholangiocarcinoma is a fatal malignant neoplasm originating from biliary tracts and constitutes about 5-10% of primary liver cancers, characterized by a poor prognosis. High prevalence in southeast and eastern Asia has been observed. At present, the cellular and molecular mechanisms leading to oncogenesis of cholangiocarcinoma remain unclear. The RAS gene product has a key role in controlling cell growth and differentiation through its intrinsic GTPase activity. Point mutations that activate the RAS protein and its downstream cascade have been observed in human tumors. Both KRAS and BRAF are members of the RAS-RAF-MEK-ERK-MAP kinase pathway which mediates cellular response to growth signals. Somatic KRAS mutations are found at high rates in leukemia, colon cancer, pancreatic cancer and lung cancer. Studies from European and Japanese groups have recently described that activating KRAS/ BRAF mutations may play a role in the carcinogenesis of cholangiocarcinoma of the biliary tracts, but our preliminary data demonstrated low frequency of KRAS and BRAF mutation in the same tumor as well as the results from Thailand. In this study, the investigators hypothesize copy number changes rather than genetic mutation of either KRAS or BRAF genes may be the key findings of Taiwanese cases of the adenocarcinoma from the biliary tracts.

To determine EGFR mutation status in patients with advanced stage adenocarcinoma NSCLC. To determine the association between EGFR mutation status and demographic data in advanced stage adenocarcinoma NSCLC patients.

For tough colic resection, evaluation of our practice for these lesions unresectable in monoblock and evaluation of the contribution of the hybrid technique EMR (mucosectomy dissection) /ESD (submucosal dissection)

BACAP is a biobank dedicated to the pancreatic adenocarcinoma funded by institut national institue du cancer (INCa) and coordinated by Dr Barbara Bournet from Toulouse hospital. This base includes clinical data and biological samples such as blood, serum, plasma, saliva, DNA and RNA from tumors cells. The mission of this prospective project is to make available to the scientific community a clinical biological base from patients with pancreatic adenocarcinoma

Pulmonary cryptococcosis often manifests as isolated or multiple nodules, easily mimicking lung cancer clinically and radiologically, which ascribes the poor sensitivity of Cryptococcus culture and rarely positive of Cryptococcal antigen test in the absence of disseminated disease. Therefore, the aim of this study was to develop a predictive scoring system from the perspective of available clinical indicators, to differentiate cryptococcosis from adenocarcinoma in pulmonary nodules, which might be beneficial for the delicacy management of pulmonary nodules.

The primary objective of this study is to evaluate the predictive value (in terms of remission) of a new technique for detecting circulating, functional, prostate cells among patients with localized adenocarcinoma of the prostate, and prior to any treatment.
