Active clinical trials for "Neoplasms"

The purpose of this study to assess the image quality of the rapid magnetic resonance imaging (MRI) compared to the standard MRI.

Patients with hyperthyroidism and/or goiter are evaluated with blood samples and scintiscan before they are treated with radioiodine for their thyroid disease. Because the investigators do not get a histologically/final diagnosis the investigators want to make sure, that the patients treated do not have a thyroid cancer when treated. The investigators have found that thyroid cancer is not overlooked.

The hypothesis of this study is that patients who suffered from acne vulgaris during adolescence are at greater risk of developing acneiform skin rash due to cetuximab.

The main purpose of this protocol is to provide expanded access to the study drug (Ponatinib/AP24534) for people with imatinib-, dasatinib-, and nilotinib- resistant/intolerant Philadelphia Chromosome Positive (Ph+) Leukemias. The other purpose of this protocol is to monitor the safety of the study drug in people with Ph+ Leukemias that have not responded to prior treatment.

To estimate the prevalence of EGFR mutation in a representative sample of patients with newly diagnosed stage IIIB/IV NSCLC in Spain (predominantly Caucasian ethnicity).

Nodular goiter is a highly prevalent disease in iodine-deficient areas. Usually nodule assessment includes ultrasonography (US) and fine-needle aspiration (FNA), but some benign nodules can hardly be distinguished from carcinomas. Elastography measures tissue elasticity using sonography, as malignancy is related to stiffness of solid organs. The investigators have designed a study to evaluate the diagnostic accuracy of elastography in nodular goiter. Consecutive patients will be assessed using US, FNA and elastography; the latter will be compared with cytology. Specificity, sensitivity, and predictive values will be calculated.

The purpose of this study is to study samples of rectal mucosa (the moist lining of the rectum) using a new light scattering technology, called partial wave spectroscopy (PWS) in patients who will undergo a standard of care colonoscopy or a flexible sigmoidoscopy and have a history of ulcerative colitis (UC).

The clinical study of making the evidence with application of Da vinci-Robot assisted low anterior resection in rectal cancer

The program will provide early access to the investigational drug BIBW 2992 to treat patients with advanced NSCLC who have failed at least 12 weeks on erlotinib or gefitinib. The Compassionate Use Programme will also provide additional safety and efficacy information on BIBW 2992 use. Named Patient Use (NPU)

The aim of the study is to assess the value of whole body diffusion weighted MR imaging (WB-DWI) as a non-invasive method. On one hand for pretreatment lesion detection and post-therapeutic tumor recurrence but also for early therapy monitoring with the intention to early identify patients with a poor tumor response. Our research group demonstrated that this technique is accurate in patients with head and neck cancer it could differentiate between viable tumor tissue and inflammatory or necrotic tissue at variable time points after completion of radiotherapy. In the literature it is stated that DWI can also predict the response to chemotherapeutic therapy. This is only true for focal MRI images (eg only in liver). This study aims to determine whether the whole body technique can efficiently be used because the distribution of metastases is systemic. The study includes two phases: In a first phase, a baseline study will be conducted; all possible injury types will be gathered to determine the variability in signal characteristics to finally determine appropriate thresholds to differentiate between benign and malignant lesions. This should allow us later on to perform prospective studies. In a second phase, different applications such as: pretherapeutic staging Detection of post-therapy recurrence Early evaluation of systemic cytotoxic therapy. The results of the DW-MRI will be compared with those of PET, CT and conventional MRI which are now routinely performed for the diagnosis of colorectal tumors. The scans will be performed in a group of patients on a 3 Tesla MR system. This system is fully approved by the European and American standards and the patients will not be exposed to radiation or contrast agents. In principle, all patients treated for gastrointestinal cancer were included after informed consent from the patient. This study is important to investigate whether DWI is accurate in the pre-therapeutic injury detection and staging of gastrointestinal tumors compared with PET / CT and DWI. In addition it is important to predict the outcome after therapy.
