Active clinical trials for "Neoplasms"

Low-grade diffuse glioma (GDBG) are rare tumors of young adults, whose ontogenesis is poorly understood. Patient management is based on the molecular profile defined by two molecular markers : mutations of the IDH genes and chromosomal 1p19q co-deletion. To date, the IDH and 1p19q statuses are determined on a single fragment collected from the tumor. In the case of GDBGs infiltrating several brain lobes, the sampling is done randomly on only one of the infiltrated lobes. An intra-tumoral heterogeneity of genetic alterations has been suggested and would impact management. Phylogenetic analysis of genetic alterations found, by high throughput sequencing, in each lobe invaded by the same GDBG will make it possible to assess intra-tumoral heterogeneity and to discuss, at a fundamental level, the hypothesis of a single tumor site with secondary diffusion or that of the convergent progression of two or three distinct tumor sites. Clinically, understanding the ontogenesis of GDBGs will improve their management because of the known link between brain location, dominant molecular profile, and prognosis.

It is well established that HPV infection has a casual and is a prognostic factor in several cancer types, including oropharynx. We wish to examine if HPV infection has a prognostic significance in nasopharyngeal carcinoma.

Thyroid carcinoma on struma ovarii (TCSO) is a rare ovarian tumor, derivate from monodermic teratomas. It represents about 0.01% of overall ovarian tumours, and 5 to 10% of struma ovarii. The diagnosis is histologic and retrospective after pelvic surgery. Because of its rarity, the treatment of TCSO is not consensual and should be validated in multidisciplinary team involved in rare ovarian carcinoma. TCSO should be taken care of as a thyroid carcinoma, in case of relapse, with systemic treatment, as tyrosine kinase inhibitor (TKI), without any clinical trial proving this benefit. Indeed, molecular profiles and genomic expression is unknown, because of studies with few patients (less than 10) contrary to thyroid carcinomas with the TCGA genomic classification. The study purposes are the outcome of the patients after the first treatment and the comparison of the genomic profil in next generation sequencing (NGS) with TCGA thyroid carcinoma profile. Thus, the treatment could be tailored, confirming the same therapy as in thyroid carcinoma.

Thoracic ultrasonography easily detects the movement of the visceral pleura on the parietal pleura This sign is absent when pleurodesis is successful.

Based on a new mass spectrometry system, body fluid samples were analyzed to verify the role of metabolite analysis in the diagnosis of pediatric medulloblastoma.

Detection and differentiation of esophageal squamous neoplasia (ESN) are of value in improving patient outcomes. Probe-based confocal laser endomicroscopy (pCLE) can diagnose ESN accurately.However this requires much experience, which limits the application of pCLE. The investigators designed a computer-aided diagnosis program using deep neural network to make diagnosis automatically in pCLE examination and contrast its performance with endoscopists.

The goal of the project is to develop and validate the BioForte technology. Its main functionality should be to in silico determine candidates for novel microbiome-based therapeutics and diagnostics. Key challenge to be solved using the technology is to detect the differences in gut microbiome between oncology patients who respond to immunotherapies and the ones who do not respond to this treatment. This technology employs machine learning methods to replace the laboratory procedure for finding valuable genomic features. Such features can be crucial to identify differences between the two populations (e.g. responders vs non-responders) to target specific strains. The samples and data collected in this clinical study will be used for clinical validation of BioForte technology. For all patients treated with immunotherapy, stool collection will be performed per patient (one stool collection before setting up immunotherapy using anti-PD1 / anti-PDL1 and / or anti CTLA4 antibodies). Samples will be sequenced by long-read sequencing technology. In parallel, we will also collect samples of peripheral blood samples (PBMC) and biopsy (FFPE).

This is a non-interventional, Phase 4 study designed to improve understanding of current clinical practice in the treatment of CLL/SLL and to describe treatment pattern and evaluate outcomes of ibrutinib-treated CLL patients in China. This study will include both retrospective and prospective data collection.

Lung cancer is the leading cause of deaths in the world. Engagement in physical activity can provide important benefits for cancer patients. The current study is a cross-sectional questionnaire survey and in-depth interview to understand the physical activity preferences of patients with lung cancer. This process could help to develop a lifestyle modification program based on our patients' needs and preferences.

Colorectal cancer (CRC) is the 3rd most common cancer worldwide. In the UK, CRC is the 4th most common cancer accounting for 12% of cancers diagnosed each year with approximately 41,300 new cases diagnosed in 2014. Surgery remains the only treatment option that can reliably achieve cure from colorectal cancer and thus nearly 20,000 major bowel resections are performed for this yearly in the UK. Surgery for these cancers however carries risk of major complications and potentially death. Selecting appropriate patients for surgery remains a challenge to cancer teams. Risk factors exist for complications after surgery for CRC, many of which can be assessed and discussed with the patient prior to surgery, so that any decision to operate is with fully informed consent from the patient. Increasing attention is being paid to a patient's frailty or fitness as one of these risk factors. Our centre has previously shown that measuring the cross-sectional area of the psoas muscle (a large muscle near the spine) from preoperative imaging could predict major complications in colorectal cancer patients (Jones 2015), however specialist software and patient height is required to make this calculation. More recently we have demonstrated that the measurement of the psoas muscle density on preoperative imaging (i.e. routine CT scans that all patients have before surgery to plan treatment), may potentially be useful to predict which patients are at most risk of a major complication (Herrod 2019). If this finding holds true when tested on a larger scale, it could be used to help surgical teams make the decision on whether to offer surgical resection, what kind of operations to perform, how to best support individuals undergoing operation and to ensure that the patient has the most information available to decide what risk they are at by having major surgery.
