Active clinical trials for "Carcinoma"

Our long-term objective is to develop a new tool based on a (molecular-biology) integrated imaging technology able to characterize and categorize hepatocellular carcinoma (HCC) patients in need of liver transplant (LT). To this end, our study aims at correlating specific imaging traits and fractional growth of individual tumors collected over a restricted time frame (T0 and at week 7 after first tumor detection), with a "molecular signature", obtained by custom microarray, histochemical and cytokine analysis. This should allow us to translate a series of purely morphologic information into a meaningful pathobiologic data sets. Validation of the integrated molecular-imaging tool will be performed prospectively by correlating the imaging-molecular data with HCC outcome in term of survival and disease-free survival after down staging procedures.

The purposes of this study are to determine the prevalence, size and impact on quality of life of lymphedema of the lower extremities after primary radical surgery with hysterectomy +/- pelvic - and paraaortic lymphadenectomy in women with endometrial uterine carcinoma FIGO (International Federation of Gynecology and Obstetrics) stage 1 and 2 to analyze risk factors for development of lymphedema in this specific group of patients. Our hypotheses are that women who have lymphadenectomy more often suffer from lymphedema, subjectively and objectively, and have an impaired quality of life. This is a Swedish multicenter study carried out in 17 departments of Obstetrics and Gynecology and in 3 departments of Oncology. All participants are treated according to the Swedish National Guidelines for Endometrial Cancer. 130 women with endometrial cancer who have a hysterectomy with lymphadenectomy (high-risk endometrial carcinomas) and 130 women with endometrial cancer who have a hysterectomy without lymphadenectomy (low-risk endometrial carcinomas) are prospectively enrolled in the study. The participants are examined preoperatively and on 3 occasions postoperatively, i.e. 4-6 weeks , 6 months and 12 months postoperatively. Determination of occurrence of lymphedema of the lower extremities are determined objectively by 1) a standardized clinical evaluation according to Bruna et al.[1] and 2) determining the leg volume according to the cone model by Sitzia [2] by systematically measuring of leg circumferences. In addition, occurrence of lymphedema is measured subjectively by the participants. On the same four occasions as the leg circumference measurements are conducted the patients complete two generic health related quality of life forms (the EuroQol EQ-5D and the Short-Form 36 SF-36) and the condition specific quality of life form for limb lymphedema (LYMQOL). Demographic and clinical data are systematically collected until one year postoperatively including occurrence of complications and given adjuvant oncological therapy such as chemo- and radiation therapy. On each occasion of clinical control a vaginal ultrasound examination is carried out in order to register pelvic and abdominal lymphocele formation or lymphatic fluid effusion intraabdominally.

The purpose of this research study is to evaluate the quantitative information of utilizing C-arm systems in liver tumor care in hopes this potential clinical combination of imaging could aid in diagnosis and evaluation of tumor therapy.

Recently, diffusion-weighted (DW) MR imaging has widened its application on various oncologic applications. Especially, it is expected the DW MRI could provide valuable information about early response evaluation after treatment using rapid apparent diffusion coefficient (ADC) value change. It has demonstrated potential usefulness in response evaluation in the liver tumors after treatments such as transarterial chemoembolization (TACE) and radiation therapy (RT). Furthermore, it is a functional imaging technique that does not require a contrast agent, it can be safely used in patients with renal insufficiency or other medical contraindications for contrast agents. The optimal assessment of early response of RT could provide one of the most important information to prescribe patient and cancer specific RT dose. It might be also important in palliative RT of HCC bone metastasis which is related with painful aggressive mass formation. This study is performed to evaluate the usefulness of DW MRI in early response evaluation after RT for HCC bone metastasis.

analysis of the risk factors of intra-hepatic distant recurrence (IDR) of hepatocellular carcinoma within 1 year after radiofrequency ablation.

The purpose of this study is to determine whether liver transient elastography performed before the surgical procedure is able to predict liver failure in patients undergoing hepatectomy for hepatocellular carcinoma.

Assessment of the concordance of the initial clinical and histological diagnosis and to explore its prognostic impact in terms of risk of recurrence.

The MUTHEC project aims to describe the mutational and transcriptomic landscape of HCC treated by curative treatments (resection, radio frequency ablation, transplantation) as well as advanced HCC together with the analysis of circulating tumor DNA.

Detection rate and isolation yield of CTC is low in squamous cell carcinoma of head and neck (SCCHN) with in vitro approaches rely on limited sample volumes. In this study, we applied a new method, the CellCollector, which could capture CTC in vivo from peripheral blood.

The purpose of this study is the investigation of new host-microbiome interactions promoting adenoma formation and adenocarcinoma progression. For that purpose, the investigators will collect saliva, stool and colon biopsy specimens from patients referred to colonoscopy or surgical resection of colorectal tumor. Besides, a questionnaire about diet, lifestyle and medical history will be collected. Sample analysis will involve simultaneous characterization of host and microbiota genomic and transcriptomic components.
