Active clinical trials for "Neoplasms"

This study proposes to investigate the association of nutritional status of a children assessed by body mass index (BMI), triceps skinfold thickness (TSFT), and mid upper arm circumference (MUAC), with body composition, measured by dual-energy X-ray absorptiometry (DEXA), in 60 children undergoing treatment of ALL at Unidad Nacional de Oncologia Pediatrica (UNOP), in Guatemala City, Guatemala. The study also aims to establish normative values of body composition in children residing in an LMIC by examining 160 healthy siblings of children under treatment, and to measure habitual physical activity in children with acute lymphoblastic leukemia (ALL) at diagnosis and during therapy.

Colorectal cancer (CRC) is among the most preventable cancers when precancerous lesions are detected at an early stage. Current screening methods for CRC require bowel prep or stool-based testing that are inconvenient, resulting in low compliance. Stool based tests have limited sensitivity for the detection of precancerous lesions. The CMx platform has been showed to be able to the detection of Circulating Tumor Cells (CTCs) in high sensitivity and specificity. In published studies, circulating Tumor Cells (CTCs) are captured and quantified in advanced-stages of colorectal cancer. In order to detect early and pre-cancer circulating tumor cells, we have developed an Automated Liquid Biopsy Platform that improves the detection of CTCs in early cancer stages. Therefore, this study goals are: 1) to establish a standard detection process utilizing the Automated Liquid Biopsy Platform. 2) Parallel comparison of laboratory manual operation and Automated Liquid Biopsy Platform. 3) Verify the feasibility of use of an Automated Liquid Biopsy Platform in the clinical setting.

Purpose: Total endoscopic thyroidectomy including oral approach and breast approach has excellent cosmetic and several functional results. Many patients, especially women, undergoing thyroid surgery are concerned about the postoperative cosmetic appearance of the neck. The procedure of total endoscopic thyroidectomy by breast approach only left three incisions, while by oral approach did not leave any incisions in the body surface, which is scarless in the neck, involved with a higher cosmetic result. However, the long-term property evaluation of total endoscopic thyroidectomy was not confirmed. The purpose of our study was to evaluate the surgical results of total endoscopic thyroidectomy (transoral approach and breast approach) versus conventional open thyroidectomy.

The purpose of the study is to assess the role of lymphoscintigraphy as a simple and widely accessible method with a favorable cost/benefit ratio in improving oral cavity and oropharyngeal squamous cell carcinoma staging and surgical appropriateness and implementing a tailored surgical approach to cervical lymph node dissection.

The purpose of this study is to determine if there are markers in plasma that can be used to develop a diagnostic panel for early detection and diagnosis of high grade serous epithelial ovarian cancer.

The purpose of this study is to investigate genetic mutations affecting prognosis using whole genome sequencing in patients with biliary tract cancer.

State of the question Over the past decade, the incidence of melanoma (MM) has steadily increased in France and in most developed countries. This increased incidence was concerned mainly MM thin while the incidence of MM thick that represent the true "killers", and mortality from MM remained stable or increased slightly over the same period. These epidemiological data and observations from everyday medical practice dermatologists suggest the existence of different growth patterns within MM. Indeed, some MM progressing slowly sometimes for decades before diagnosis but are thin at the time of resection. Conversely, others MM grow very quickly, resulting in thick tumors despite a diagnosis and resection sometimes very early. These fast growing MM (FGMM) probably contribute significantly to the relative mortality in MM, as improved screening failed to influence to this day. Our team has already demonstrated that the growth kinetics of the MM was a prognostic factor of tumor aggressiveness regardless of the thickness of the tumor. Using the same method to calculate the growth rate, an Australian team recently studied the growth rate in a population of patients suffering from MM. In this population 1/3 of MM had a growth of more than 0.5 mm per month. Clinical aspects and FGMM of these risk factors were individuals (injuries symmetrical achromic and regular occurrence among about older and low-nevi). The European and Australian people are very different in particular regarding the prevention policy, these results can not be extrapolated to the French population.The main objective is to identify risk factors for FGMM in French propulation

The goal of this laboratory research is to look for genes that can predict which patients will achieve a complete disappearance of their colorectal cancer after treatment like chemotherapy, radiation, or other therapy. This is an investigational study. Up to 350 patients will take part in this study. All will be enrolled at MD Anderson.

Children and adolescents with Hodgkin lymphoma currently undergo multiple investigations including a separate PET and MRI scans during their treatment. Investigators want to investigate if a combined PET-MRI scan could give the same information. Children who join our study will have an extra scan twice during their treatment

The purpose is the description of anti-tumor immune responses in general and according to clinical stage and disease free survival (DFS: survival without recurrence (local or distant)) in patients with Head & Neck Squamous Cell Carcinoma Secondary purposes are: Study of relationship between anti-tumor immune response and qualitative (yes/no) and quantitative (number) presence of circulating tumor cells (CTCs); Study of relationship between qualitative (yes/no) and quantitative (number) presence of CTCs and clinical stage as well as DFS Study of relationship between anti-tumor immune response and clinical stage as well as DFS.
