Active clinical trials for "Neoplasms"

This is a multicenter, prospective, translational study, to evaluate the immunogenic profile of AML cases according to immune checkpoint molecule expression.

Since other genital infections enhance HIV susceptibility by inducing inflammation, the investigators study the relationship between the vaginal microbiota composition and the risk of HPV infection, cervical cytological abnormalities in postmenopausal women.

This is a observational study on the fecal microbiota in primary/secondary gastrointestinal lymphoma patients.

Bone metastasis (i.e. cancer cell spreading to bone) is the major clinical problem of advanced breast cancer patients. Bone metastasis is not curable nor preventable. Currently available therapeutic approaches are only palliative. The major hurdle for improving bone metastasis treatment is lack of sensitive diagnostic tools. Diagnosis of bone metastasis is heavily dependent on radiographic imaging of bone destruction that are detectable only when the lesion is significantly large. Accordingly, if bone metastasis can be detected at an earlier time point when bone destruction is minimal or incipient, treatments can be given earlier and the patients can expect better outcomes. We and others previously have found that a subset of bone-forming cells (i.e. circulating osteocalcin-positive cells) exists in the blood stream of the patients with bone diseases (e.g. bone metastasis and inflammation) or active bone formation (e.g. adolescence) in mouse models anf human samples. Extended from this laboratory observation, this clinical study proposes to test the hypothesis that circulating osteocalcin-positive cells are the early biomarker of breast cancer bone metastasis. For this aim, this study will measure circulating osteocalcin-positive cells in the blood samples of breast cancer patient, and examine whether the measure sensitively detects bone metastasis.

The aim of this study is to analyze aquaporins expression of thymic epithelial tumors and to compare them with apparent diffusion coefficient(ADC) from ultra-high b-values, and to test a possibility of use of ADCuh to identify the pathological type of tumor.

The designed study follows up on the previous one by the international T-cell project (Bellei et al,, 2012) and its purpose is to verify whether a prospective collection of data would permit access to more accurate information permitting a better definition of prognosis and investigation of more adequate treatment strategies for these neoplasms. The analysis of patients distributed in all five macro regions of the country and a comparison among them will provide a real picture of the disease in Brazil, limiting the bias probably found in the previous projects.

Response Evaluation Criteria in Solid Tumors (RECIST) are insensitive in evaluating primary sarcoma originated from bone treated with chemotherapy or targeted therapy, which did not have the definition of measurement methods either. This study evaluates whether clinical imaging findings of sarcoma after preoperative chemotherapy correlate with tumor responses by pathological evaluation by Huvos classifications and develops reliable, quantitative, clinical response criteria.

The classification of lung cancer (LC) according to the degree of anatomical extension (TNM) allows the estimation of the prognosis of the patient, although its accuracy is limited. In fact, one third of surgically-treated patients with initial disease have recurrences during follow-up, despite the negativity of node dissection at surgery. The incorporation of genetic, epigenetic and proteomic information to TNM staging will characterize more accurately the lung cancer, and thereby improve the prognostic and the prediction of the therapeutic response in these patients.In this project a prospective cohort of 320 patients with lung cancer staged I-IIp will be studied, combining the clinical and pathologic information available with genetic, epigenetic and proteomic markers in tumour samples, pulmonary tissue, regional nodes and peripheral blood, preserved in suitable systems for the application of complex analytical methodologies. Thus, a knowledge database will be created with the aim of improving the prognostic and prediction capabilities of TNM staging.This project is coordinated with related sub-projects that cover the required laboratory tests on biological samples and with Spanish collaborative group in lung cancer.

Type 1 - Multiple Endocrine Neoplasia syndrome (MEN1,) is an autosomal dominant disorder secondary to MEN1 mutations that predisposes carriers to endocrine tumors. The MEN1 gene located on chromosome 11q13 encodes menin, a 610 amino acid protein expressed in all tissues tested. Menin is a scaffold protein which interacts with a large number of intracellular molecules. MEN1 disease may display various clinical associations The tumors mainly develop from endocrine tissues and may arise from parathyroid glands, duodeno-pancreas, pituitary gland, adrenal glands, and at a lower frequency from the bronchi and thymus. The penetrance is very progressive but ultimately high during a lifespan. Although the syndrome was discovered in 1903 by Erdheim and properly documented in 1954 by Wermer, it was only in the 1970s that the variety of clinical presentations was acknowledged and first attempts to codify treatments were made. Most published studies deals with selected and small size populations. Thus, many aspects of the natural history of MEN1 remains unknown as well as the optimal care of patients. In addition, although advances in genetics improved the diagnosis of MEN1, there are still clinical forms whose attachment to the syndrome is difficult: atypical, paucisymptomatic, forms the negative genetic diagnosis (10%). These clinical forms need to be clarified to ensure optimum support. This cohort relies on the Groupe d'étude des Tumeurs Endocrines (GTE) network for MEN1, created in February 1991, and brings together clinical centers in France and Belgium (n=80) as well as the four genetics laboratories in charge of MEN1 diagnosis. It aims at improving the knowledge of the MEN1mainly in describing: its evolution over time globally and according to the initial presentation, ( particularly accounting the risk of the occurrence of secondary MEN1 related or unrelated tumors, and death) the genotype-phenotype correlations and heritability of the disease the real life management of patients and its impact on cure and survival for each type of MEN1-related tumor the impact of the NEM on the patients' daily lives, their perception of the disease and their satisfaction with their care

Study Purpose: A multicenter prospective study to evaluate the outcome of second breast cancer surveillance with abbreviated breast MR (AB-MR) or ultrasound (US) in addition to annual mammography in women with BRCA1/2 mutation testing Study Scheme: AB-MR, US, and digital mammography will be performed on the same day and interpreted independently at baseline and then after 1 year. After completion of study, patients are followed-up for at least 1 year.
