Active clinical trials for "Adenocarcinoma"

The purpose of this study is to determine whether early recurrence after curative resection of ductal pancreatic adenocarcinoma can be explained by either dissemination of cancer cells during intraoperative tumour manipulation, post-operative systemic immune suppression, alteration of biological properties of circulating cancer cells or a combination of these.

This clinical trial studies adherence to survivorship care guidelines in health care providers for non-small cell lung cancer or colorectal cancer survivor care. The completion of an educational intervention by health care providers may increase compliance and adherence to National Comprehensive Cancer Network guidelines for survivorship care.

This is an assisted exercise trial involving exercise on a stationary bike, brain imaging and DNA(genetics)sampling. The purpose of this study is to find out if performing a progressive, supervised assisted exercise program on a stationary bike improves quality of life, increases motivation to continue to exercise, improves dietary behavior and leads to sustained weight loss in women who have had early-stage endometrial cancer. Questionnaires will be used to assess exercise motivation and dietary behavior. Brain's responses to different visual images will also be assessed.

The aim of this study was to assess the diagnostic accuracy of PET-MRI to predict resectability of pancreatic adenocarcinoma after neoadjuvant chemotherapy ± radiation therapy.

Nasal adenocarcinomas are closely related to wood dust exposure. The precise mechanisms of carcinogenesis leading to the transformation of the respiratory mucosa into a colonic-like mucosa remain unknown: chronic exposure to wood dust may cause chronic inflammation that may lead to pre-degenerative lesions, hypothesis yet unconfirmed. The tumor development requires the activation of a particular gene: CDX2. The working hypothesis is that chronic wood dust exposure is responsible for changes in genes of inflammation, which can in turn lead to changes in the expression of CDX2 and its cofactors, thus making possible the genesis of adenocarcinoma. This work is a pilot study aiming to better understand the mechanisms of carcinogenesis, and to study the feasibility of a larger prospective screening for woodworkers adenocarcinomas. Cells will be obtained from the at risk area (olfactory cleft) by a noninvasive method (brushing) in healthy volunteers (unexposed to wood dust) and in exposed volunteers to compare their genomes and study the genomic changes related to wood dust exposure.

Pancreatic cancer is a highly aggressive malignancy, its prognosis remaining poor despite the current advances in treatment. Systemic inflammatory reaction has been recently recognized as an important factor in the progression of cancer. The immune-inflammatory response has been measured through different scores or ratios, that combine the values of circulating immune cells, like neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), systemic immune-inflammation index (SII), prognostic nutritional index (PNI). The utility of these scores in different types of cancer has been more and more discussed. In pancreatic cancer, there has been no definite conclusion regarding the role of systemic immune-inflammatory factors; since controversies still exist, a deeper exploration of this subject, through more studies is welcomed. Our study intends to analyze the utility of systemic immune-inflammatory markers in resectable pancreatic cancer. Our study is an observational cohort study, with retrospective data collection; it is a single-center study, that takes place in a hospital with experience in hepato-bilio-pancreatic surgery. The investigators intended to evaluate the role of the circulating immune cells (neutrophils, lymphocytes, monocytes) and different immune-inflammatory scores (NLR, LMR, PLR, SII, PNI) in predicting the overall survival of patients diagnosed with pancreatic ductal adenocarcinoma, that undergo curative surgical treatment. The investigators intended to assess the prognosis power of these factors in both preoperative and postoperative settings, as well as their dynamic after surgery. Through this study, the investigators hope to identify easy-to determine and easy-to-use markers that can be incorporated in clinical practice and that can effectively predict survival in pancreatic cancer patients. Nonetheless, the investigators want to explore the dynamic of the immune-inflammatory markers after curative surgery.

Spread through air space (STAS) has been reported as a negative prognostic factor in patients with lung cancer undergone sublobar resection. Its preoperative assessment could thus be useful to customize surgical treatment. Radiomics has been recently proposed to predict STAS in patients with lung adenocarcinoma. However, all the studies have strictly selected both imaging and patients, leading to results hardly applicable to daily clinical practice. The aim of this study is to test a radiomics-based prediction model of STAS in practice-based dataset and verify its validity and translational potentials. Radiological and clinical data from 100 consecutive patients with resected lung adenocarcinoma were retrospectively collected for the training section. As in common clinical practice, preoperative CT images were acquired independently by different physicians and from different hospitals. Therefore, our dataset presents high variance in model and manufacture of scanner, acquisition and reconstruction protocol, endovenous contrast phase and pixel size. To test the effect of normalization in highly varying data, preoperative CT images and tumor region of interest were preprocessed with four different pipelines. Features were extracted using pyradiomics and selected considering both separation power and robustness within pipelines. After that, a radiomics-based prediction model of STAS were created using the most significant associated features. This model were than validated in a group of 50 patients prospectively enrolled as external validation group to test its efficacy in STAS prediction.

This study will investigate whether liquid based cytology specimens are a feasible alternative to formalin-fixed paraffin embedded histology samples for detection of epidermal growth factor receptor (EGFR) mutations in lung adenocarcinoma using the Biocartis Idylla platform. The Biocartis Idylla is a fully automated, real-time PCR based molecular diagnostics system. The Idylla carries out the entire analytical process from sample to result. This study will be based in the cytology department at Royal Cornwall Hospital as part of a service improvement. It will use residual material from existing samples sent to the laboratory as part of the routine service. It will use existing material from patients diagnosed with lung adenocarcinoma by cytology using the current, validated procedure which uses formalin-fixed paraffin embedded (FFPE) samples over a 10 month period. EGFR mutation results obtained using the validated procedure (formalin fixed paraffin embedded) will be compared to those produced using liquid based cytology samples.

Fruquintinib with PD-1 inhibitors (FP) and TAS-102 with bevacizumab (TB) are two common therapies for patients with previous-treated metastatic colorectal cancer (mCRC). However, it's still not clear that which therapy can bring better prognosis. Our study sought to investigate the efficacy and safety of fruquintinib with PD-1 Inhibitors versus TAS-102 with bevacizumab in Late-Line mCRC between July 2019 to October 2022July 2019 and June 2021 at the Hunan Cancer Hospital.

The majority of primary cancers of the ovary or peritoneum are represented by high-grade serous adenocarcinomas. These are rare pathologies, the incidence of which is estimated at 7.1 per 100,000, representing approximately 4,500 new cases per year in France (INCA 2017). In the absence of effective screening, nearly 85% of patients have an advanced disease at diagnosis (corresponding to the FIGO III or IVA stage, characterized by diffuse peritoneal involvement). Despite multidisciplinary care, the majority of patients (80%) will recur within a median of 18 to 24 months. It is therefore necessary to develop new tools, in particular molecular, in order to allow : to better select patients accessible to full interval surgery to exclude patients who would not benefit from this surgery in terms of survival In 2010, Chibon et al. identified, from a cohort of patients with soft tissue sarcoma (STM), a molecular signature (called CINSARC), based on the expression profile of 67 genes involved in mitotic control and chromosomal integrity. The team showed that this transcriptomic signature is an independent prognostic factor in different types of STM, but also a prognostic factor more discriminating than the histological grade (FNCLCC), historical and major prognostic factor of STM. Being initially made from frozen material and on a DNA biochip (Affymetrix), this signature was unusable outside the field of fundamental research. This is why CINSARC has been gradually optimized, first by the RNA sequencing technique on frozen tissue fixed in formalin (FFPE), and recently on FFPE tissue by the NanoString® technique. This very sensitive and inexpensive technique requires only small amounts of total RNA, making it compatible with use on "routine" diagnostic samples, microbiopsy or surgical biopsy, opening the door to real clinical application. Several clinical studies using this latest CINSARC optimization (called NanoCind®) to determine the treatment of patients with STM will also begin soon. As a result of this work, necessary in order to more precisely support the potential of CINSARC in this pathology, the investigators hope to be able to assess from the diagnosis the evolutionary potential of the patients, which could make it possible to evaluate therapeutic strategies adapted to the profiles of each subpopulation: the investigators can for example imagine in theory a therapeutic de-escalation for low-risk patients, or else, for very high-risk patients, an intensified strategy.
