Filter by:Diagnosis of lesions of pancreas, the upper gastrointestinal tract, as well as adjacent structures, such as lymph nodes, is still showing advancements especially with the increased use of endoscopic ultrasound. Endoscopic ultrasound-guided fine needle aspiration and fine needle biopsy (EUS-FNA/FNB) have become mainstay diagnostic techniques for these lesions. The purpose of the study is to compare between the currently used, ProCore needles and the new biopsy needle, SharkCore, for the histological diagnosis and evaluation of lesions.
Oncogenic osteomalacia is rare disease predominantly caused by a small, somatostatin receptor positive mesenchymal tumor, which is frequently hidden in an unusual anatomical site and often goes undetected by conventional imaging. A permanent cure of the disease relies on exactly localizing the tumor and completely removing it. 68Ga-DOTATATE PET/CT is a novel scan that might have improved sensitivity and resolution specifically for somatostatin receptor positive tumors. The investigators will scan the suspicious and confirmed patients of oncogenic osteomalacia and compare it to 99mTc-HYNIC-TOC SPECT/CT and 18F-FDG PET/CT to see if it improves patient care.
Uterine sarcomas account for less than 5% of all carcinomas of the uterine corpus. The prognosis of these patients is extremely limited. Recurrence rates of 50-60% are reported even for early-stage disease (FIGO I/II). Median overall survival is below 12 months in patients with advanced or metastatic disease. Ovarian carcinosarcoma is extremely rare among ovarian malignancies (< 2%). That is why there is insufficient data as a basis for establishing a gold standard. As a result, these cases tend to be treated in the same way as uterine sarcomas or epithelial ovarian malignancies in clinical practice. On the basis of data published to date on the treatment of mixed mesenchymal-epithelial tumors, it is clear that the treatments commonly used to date have limited activity while producing clinically relevant toxicity. The regimes verified so far (Cisplatin / Ifosfamide, Ifosfamide/Paclitaxel and Gemcitabine/Docetaxel) exhibit a considerable side effect spectrum and are only rarely feasible on clinical everyday life conditions, so e. g. the rate of withdrawals due to toxicity was in a study collective of selected females treated with the last combination at 40 %. The physician has to check in every individual case if one of the above mentioned combinations is feasible. The search for alternative effective and better tolerated treatment options is essential. The toxicity data on the carboplatin-PLD combination are known, and efficacy has been identified in small cohorts. The objective of this study is to explore the efficacy of combination PLD-carboplatin treatment in a larger patient population.
The purpose of this study is to test the effectiveness of high dose radiation administered by both proton and photon therapy. Radiation is an effective treatment for many types of tumors and it is thought that radiation alone, when given in much higher doses over a shorter period of time, may be more effective in controlling recurrence of sarcoma.
