Active clinical trials for "Neoplasms"

This study aimed at study the clinical and pathological criteria of Hepatocellular carcinoma to keep with new challenging in diagnosis and morpho-molecular classifications

The aim of the study is to analyze the implementation of the 2018 updated ESMO Guideline in patients with tumor diseases as well as the corre-sponding recommendations of the Onkopedia Guideline and the S3 Guide-line Supportive Therapy in routine clinical practice in Germany. To this end, a nationwide, representative, retrospective patient documen-tation will be conducted to observe the current practice of anemia man-agement in hospitals and among office-based physicians.

Early onset colorectal cancer (cancer in person younger than 50 years) has increasing incidence last years. The aim of our study was to assess the real-life incidence of early onset colorectal cancer, advanced neoplasias (colorectal cancer and/or advanced adenoma) and all neoplastic lesions in total in a single non-university endoscopic center.

The main objective of the study is to assess the trend of clinicopathological features and treatment modalities in patients with thyroid cancer in the largest oncology center in the United Arab Emirates (UAE).

In a retrospective study, the investigators will compare patients with locally advanced rectal cancer with high risk factors for failure who were treated with standard therapy or with total neoadjuvant therapy.

This is a retrospective biobank study evaluating the impact of novel genetic variants in a population of 6-mercaptopurine treated pediatric acute lymphoblastic leukemia patients.

Thyroid nodules are common in clinical practice. Head and neck ultrasound is recommended as a routine examination for all patients with thyroid lesions. The Thyroid Imaging Reporting And Documentation System (TIRADS) criteria helps to estimate the risk of malignancy based on ultrasound patterns and nodule sizes guiding the performance of fine-needle-aspiration (FNA). Approximately 20% of FNA results cannot be specified whether being benign or malig-nant tissue. A definitive diagnosis can only be made from histopathology after diagnostic (hemi)thyroidectomy. However, (hemi)thyroidectomy has disadvantages as it leads to over-treatment and has a risk of postoperative morbidity (e.g. hypothyroidism and laryngeal nerve injury). Furthermore, (hemi)thyroidectomy is known to be associated with poor quality of life. Clearly, there is an unmet need for additional diagnostic tools in order to identify malignant thyroid nodules and thereby support the decision making for treatment of the thyroid. Multispectral optoacoustic tomography (MSOT) is an innovative, non-invasive imaging method currently available in the UMCG that enables visualization of endogenous chromophores and exogenous contrast agents using the generation of ultrasound waves due to light absorption by using high frequency pulsed laser light. Recently, this system has been used by other groups for non-invasive determination of thyroid nodules. Results show that multispectral optoacoustic imaging of thyroid nodules may distinguish benign from malignant nodules. However, most certainly, a larger cohort is necessary to confirm this finding.

There are many factors involved in outlining the patient's profile and in defining which factors can be configured as risks related to the surgical act; for the modern surgeon it is no longer possible to identify the patient at risk of complications based on the mere age or some comorbidities historically considered more influential on the surgical outcome, but each patient must be evaluated in its entirety including age, fragility, comorbidity, state nutritional and sarcopenia and, if necessary, implementing preoperative therapeutic strategies aimed at minimizing the impact of some of these factors on the outcome of surgery. Our study aimed at creating, if possible, an "identikit" of the patient who is more likely to have serious postoperative complications; in order to improve the therapeutic decision and the approach to patients with severe surgical risk since choosing the right treatment for the right patient is essential to obtain a good result.

The aim of this study is to compare tissue quality and molecular yield between a novel crown-cut biopsy needle (FNB) and a standard aspiration needle (FNA) for EUS-guided diagnosis of solid pancreatic lesions.

In this prospective, non-randomized cohort study, real-time intraoperative visualization using near-infrared-fluorescence by indocyanine green injection (ICG-NIRF) is performed at three time points during ileal pouch reconstruction. The intraoperative imaging findings are then analysed and correlated with the 30 day postoperative clinical outcome including occurrence of anastomotic leak of the pouch.
