Active clinical trials for "Neoplasm Metastasis"

Data from 26 patients undergoing resection of Pancreatic Metastases and extra-Pancreatic Metastases from RCC were retrospectively analysed. Clinical data were collected from a digital database and QoL was assessed through patient's interview and Karnofsky performance scale.

Pancreatic Neuroendocrine Neoplasms (PanNEN) are a heterogeneous group of neoplasms that arise from the endocrine cells of the pancreatic gland. Non-functioning (NF-PanNEN) represents the most common forms and do not produce syndromes due to hormonal hypersecretion. Several prognostic factors have been demonstrated for NF-PanNEN. The presence of nodal metastasis and lymph node ratio are widely considered predictors of disease-free survival and even the number of positive nodes has been found to be associated with recurrence. In addition to traditional imaging exams, diagnostic work-up should include a Positron Emission Tomography/CT with 68Ga labeled somatostatin analogues, which have shown a high sensitivity and specificity while 18F-FDG PET can be associated for evaluating the possible presence of a high-grade component. Moreover, pancreatic endoscopic ultrasound (EUS) is usually part of the preoperative staging both for imaging details and cytological sampling. Therefore an accurate identification of nodal metastases preoperatively may have important implications for the extent of surgical resection and lymphadenectomy and even for a prognostic outcome. In this study the investigators will evaluate prospectively the accuracy of these diagnostic exams in detecting the lymph node status. Patients with sporadic NF-PanNEN who are candidates for surgical resection will undergo CE-CT scan, 68Ga DOTATOC (and eventually 18F-FDG) PET/MRI and EUS with FNA/B. Reference standard for defining the presence of nodal metastases is represented by pathological examination on the specimen.

Single Patient Expanded Access

The purpose of this study is to determine if the use of the Prevena™ System decreases the rate of subcutaneous seroma, superficial wound dehiscence and infection.

Colorectal cancer is a major cause of mortality worldwide. Most patients develop colorectal liver metastases (CLM), and for such patients hepatectomy combined with chemotherapy may be curative. Nevertheless, in the era of precision medicine there is a critical need of prognostic markers to cope with the heterogeneity of CLM patients. Tumor-associated macrophages (TAMs) pave the way to tissue invasion and intravasation providing a nurturing microenvironment formetastases. The quantification of immune landscape of tumors has provided novel prognostic indicators of cancer progression, and the quantification of TAMs might explain the heterogeneity of CLM patients. Here, we will investigate the development of a new diagnostic tool based on TAMs with the aim to define the causative role of TAMs in CLM patients. This will open new clinical scenarios both for the diagnosis, therapy and prognosis, leading to the refinement of the therapeutic output in a personalized medicine perspective.

The aim is to conduct a single centre retrospective study of all patients with stage IV melanoma that underwent surgery for metastases at Sahlgrenska University Hospital between 2010-01-01 and 2018-12-31. Pre- and postoperative data will be collected from digital medical records, the Swedish Cancer Registry, the Swedish Cause of Death Register as well as from the national Swedish cancer patient database (INCA). If needed, patient records will be collected from other hospitals. Results will be presented in written format as a summary and analysis of the characteristics of the cases operated on during the inclusion period. The aim is to identify predictive and prognostic factors for outcome and complications in the surgical treatment of stage IV metastatic melanoma.

Papillary thyroid microcarcinoma (PTMC), defined as a tumor with larger diameter ≤ 1 cm, is considered a tumor with an indolent course and an excellent prognosis. Nevertheless, the incidence of lymph node metastasis in PTMC is not negligible, reaching up to 65% in some series. The aim of this study was to assess the incidence of lymph node metastasis in patients with PTMC and to evaluate predictive factors for lymph node metastasis.

Given the dismal prognosis of pancreatic cancer, detecting liver metastases early can avoid inappropriate therapy with the associated substantial risks, long-term hospital admissions and high costs, but without survival benefit. The current standard of diagnostic workup with contrast-enhanced CT (CECT) has a poor sensitivity (38-76%) for the detection of liver metastases. As more sophisticated and expensive treatment options emerge, better staging of pancreatic cancer is needed to avoid unnecessary procedures and select the most appropriate treatment strategy. New imaging modalities are available, but their value in staging of pancreatic cancer has not been evaluated yet. Therefore prospective imaging studies are necessary. The main aim of this study is to determine the diagnostic accuracy of contrast-enhanced diffusion-weighted MRI (CE-DW-MRI) in the detection of liver metastases in patients with pancreatic cancer compared to a reference standard of histopathology and follow up imaging. The study is an international, multicenter prospective cohort study (inclusion of patients until 138 patients with liver metastases are included, with a total maximum of 465 patients). Patients with pancreatic cancer will undergo additional CE-DW-MRI within two weeks from the CECT. CECT and CE-DW-MRI will be read independently by two radiologists. Suspected liver lesions on CECT and/or CE-DW-MRI will be biopsied to obtain histopathology as reference standard. For liver lesions without histopathologic proof of metastases a paired follow-up CECT and CE-DW-MRI serve as a composite reference standard. Pancreatic resection will be pursued in patients without proven liver or distant metastases. Patients with locally advanced or metastatic disease will be offered palliative treatment. Follow up CECT and CE-DW-MRI will be performed in all patients at 3, 6, and 12 months.

This study aims to evaluate the prognostic value of circulating tumour cells (CTC) in patients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy due to gastrointestinal cancers that have spread to the peritoneum.

The aim of this study was to develop a practical protocol based on the ICF(The International Classification of Functioning, Disability, and Health) the risk factors of cardiovascular disease (CVD) in secondary prevention.
