Active clinical trials for "Carcinoma"

Aim 1: To compare the overall toxicant exposure in pregnant women who use electronic cigarettes (e-cigs, vapor, e-liquid, e-juice, vape, vaping devices) compared to women who smoke conventional cigarettes. Aim 2. To compare toxicant exposure and birth outcomes among infants born to pregnant women who use e-cigs compared to women who smoke conventional cigarettes. Aim 3. To explore potential mechanisms by which e-cigs could influence birth weight.

Although children and adolescents are more likely to have advanced disease at onset, they generally have a significantly better chance of survival. With combined chemotherapy and radiotherapy, overall survival has been reported more than 75% in most pediatric studies. However, little research focuses on long-term morbidities of children and adolescent nasopharyngeal carcinoma (NPC) survivors, and most studies are small scale and have short follow-up time. Therefore, this study analyzed the long-term morbidities of children and adolescent NPC survivors after radiotherapy. Factors associated with those morbidities were also analyzed. We reviewed the medical records of all NPC patients younger than 18 years old treated at Sun Yat-sen University Cancer Center (SYSUCC) from February 1991 to October 2010. Detailed medical records were taken from our institutional database. Patients were also followed using comprehensive questionnaires and phone calls. We extracted data on clinical characteristics, histopathology, imaging findings, treatment, outcomes, and late morbidities. Patients with early-stage (stage I and II) disease were treated with radiotherapy alone, and patients with advanced-stage disease (stage III and IV) were treated with a combination of radiotherapy and chemotherapy. Radiotherapy technology included conventional radiotherapy (CRT) and intensity-modulated radiotherapy (IMRT). We retrospectively reviewed these medical records to collect the required data. All survivors returned to the hospital for follow-up examinations at least every 3 months for the first year, at least every 6 months in the 2nd year, and at least every one year thereafter until the latest follow-up. As part of our routine clinical practice, all patients underwent follow-up MRI examinations of the nasopharynx and neck at least every 6 to 12 months. Radioactive toxicity on organs was evaluated based on National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 3.0. Analyses were performed using SPSS software, version 16.0 (SPSS, Chicago, IL). Chi-squared tests and binary regression analysis were used to compare the CI of treatment comorbidities between different groups of survivors. A P value of 0.05 was chosen as the criteria for statistical significance.

The goal of this imaging study is to evaluate and improve the treatment planning techniques for abdominal radiation therapy. To accurately treat a tumor with radiation, Computed Tomography (CT) and Magnetic Resonance Images (MRI) are used to distinguish a tumor from normal, healthy tissue. However the quality of these images can be distorted by motion from breathing. To decrease motion, a patient may be asked to hold their breath or compress the abdomen, but currently there is no standard or best management option for all patients. This study will explore the use continuous positive airway pressure (CPAP), a pressurized breathing mask, during MRI or CT imaging to decrease motion in the abdomen and produce higher quality images. With these additional images, we will also explore the feasibility of creating treatment plans using the CPAP MRI images alone.

To validate ELISAs for the detection of urinary tissue factor (TF) in patients suspected of having bladder cancer.

Hepatocellular carcinoma (HCC) is the 6th most common cancer in the world but the 2nd most important cause of cancer death. Because of its highly heterogeneous nature, the current approach to identifying druggable targets have not delivered efficacious therapies in HCC and is a main reason for the high case fatality. Even when surgical resection is potentially curative in early disease, tumor recurrence remains high and long term survival poor because of the absence of useful adjuvant therapy. To address these unmet needs, the investigators bring together internationally recognized scientists from genomics and immunology and established clinician investigators in a synergistic team. This TCR capitalizes on recent collaborative advances made by the PIs in the consortium. The investigators have shown through multi-region sampling of freshly resected HCC and phylogenetic analysis, that significant intra-tumoral heterogeneity exists and have identified the specific positions of known clonal drivers. Simultaneously the investigators have analyzed the immune landscape of the tumor microenvironment with deep immune-phenotyping and found unique inter-patient immune landscapes predictive of clinical trajectory. This TCR is a prospective study that samples resected HCC from multi-ethnic sites within the established Asia-Pacific Hepatocellular Carcinoma (AHCC) Trials Group, which has enrolled approximately 1000 patients through 6 multi-center trials in 35 centers in the region. Clinical trajectories are tracked and genomic and immunological studies are repeated when tumors recu r, to confirm clonally dominant driver mutations and immunological processes that are targetable. Concurrently, representative pre-clinical models will be developed from the tissues sampled. The investigators aim to combine these approaches to overcome the challenges posed by genomic heterogeneity and to guide the development of therapeutics and precision medicine in HCC.

This surveillance's objectives are: Unknown adverse reactions Incidences of adverse drug reaction Factors considered to have effect to safety and effectiveness

This research trial studies biomarkers in patients with previously untreated invasive ovarian epithelial, fallopian tube, or primary peritoneal cancer. Studying samples of tumor tissue, peritoneal cavity fluid, and blood from patients receiving chemotherapy directly into the abdominal cavity (intraperitoneal) may help doctors learn more about the effects of intraperitoneal chemotherapy on cells. It may also help doctors identify and learn more about biomarkers related to cancer.

Despite novel treatment options, Renal Cell Carcinoma (RCC) has been characterized by a constant increase in its mortality and consequently requires an important involvement in translational research. The aim of this study is to evaluate the interest of CXCL4, CXCL4L1 and CXCR3 as biomarkers in localized, locally advanced or metastatic RCC. Indeed these chemokines have shown anti-angiogenic and anti-tumor properties in experimental models and may be particularly interesting for prognostic and predictive purposes.

TheraSphere is a medical device containing yttrium-90 (Y-90) a radioactive material that has been used to treat liver tumors. When Y-90 is put into very tiny glass beads (TheraSphere), it can be injected into the liver through a blood vessel. This allows a large local dose of radiation to be delivered to the tumor with less risk of toxic effects from radiation to other parts of the body or to healthy liver tissue.

100 patients with metastatic and/or advanced renal cell carcinoma treated with sunitinib (Sutent) will be inclued and followed with standard care plus a call center Principal assumption : the proportion of patients presenting with at least one grade 3 or 4 AE (whether related to sunitinib or not).
