Active clinical trials for "Neoplasm Metastasis"

SC-CIP is increasing in patients after critical illness. Pathogenesis is still largely unclear. Gut microbiome composition, gut permeability, bacterial translocation, inflammation and/or genetic variants contribute to the pathogenesis The aim of this project is to study gut microbiome composition, gut permeability, bacterial translocation, inflammation, bile acid composition and genetic polymorphisms by conducting a prospective cohort study in patients with a high risk to develop SC-CIP.

Peritoneal metastasis of gastric cancer is difficult to be detected in time, thus delaying treatment. Based on the conventional CT images of gastric cancer, this study plans to develop, improve and validate an intelligent analysis system based on radiomics. By extracting and combining the radiomics features related to peritoneal metastasis of gastric cancer, the intelligent analysis system could predict the risk of peritoneal metastasis, and provide personalized decision suggestions for the treatment of gastric cancer.

By incorporating dual-tracer PET/CT (PSMA and FDG) and ctDNA, we aimed to evaluate lesion heterogeneity and genomic change of mCRPC patients receiving novel hormonal therapy. The relationship between treatment response and different molecular characterization, as well as imaging features would also be evaluated.

This prospective single arm double-blind study approved by the Ethics Committee of the institution, will be conducted on at the Oncology Institute of Vojvodina in Sremska Kamenica, Serbia. Patients with colo-rectal cancer liver metastases (CRLM) is presented to the multi-disciplinary team (MDT).Screening and enrolment is conducted after established of indication for resection. The surgeons assesses resection margin (RM) for every resected liver specimen (RLS) intra-operatively by inspection and palpation. These data will be compared with pathological RM examination as a "gold standard". Resection margin of 1 mm or more will be rated as negative RM (RM-) otherwise RM is positive (RM+). Taking the result of the pathohistological examination as "gold standard" it is determined that RM is true positive when the pathologist and surgeon agreed that the RM is positive. False negative RM is when the surgeon assesses RM as negative and pathologist as positive. The sensitivity of the surgical assessment of RM+ is defined as the rate of RM+ which was correctly identified. True negative RM is determined when the pathologist and surgeon agreed that it is negative RM. False positive RM defined when the surgeon assessed RM as positive, but pathologist found that it was RM-. The specificity of the surgical assessment of RM is defined as the rate of RM- which is correctly identified. Total accuracy represents the rate of correctly recognized positive and negative RM, relative to the total number of samples. Agreement between surgeon and pathologists finding will be analyzed as well as difference between them. Disease recurrence and disease-free survival (DFS) will be analyzed by RM.

This study represents a survivorship protocol that focuses on cognition and health-related quality of life (HRQoL) in cancer patients that have received prior brain irradiation. The primary purpose of this study is to assess the feasibility of using a digital symptom tracking application focused on HRQoL and cognition in cancer survivors who received brain irradiation.

Preoperative chemotherapy is often used for patients with colorectal cancer liver metastasis (CLM). Many small CLMs (<=2cm) may disappear after chemotherapy, while most of these are still alive. Ultrasonography (US) is a common imaging modality for the intraoperative detection tumor. Sonazoid is new echo-contrast agent, which is more stable and sensitive for detecting of small tumor. Investigators initially this prospective study to compare the detection performance before and after using sonazoid.

This is a comparative study using resected/ biopsied tumors samples collected from renal cell carcinoma and urothelial carcinoma patients who underwent surgical removal of lesions, followed by immune checkpoint blockade (ICB) treatment targting programmed cell death 1 (PD1) but developed new lesions later were also removed and stored in the biosample repository (BSR). The histology and genomic analysis of the pre-treatment and metastatic samples from the same patient would be used to find out the changes that may have lead to metastasis. Also, metastatic samples from ICB naive patients would be collected and compared with those from ICB treated patients to find out if the metastasis in treated patients was due to development of reistance.

After "wedge resection" surgery, the physiotherapy programs proposed in the literature are heterogeneous and there are few data on the outcomes of such treatments in an oncological population for bone cancer. The aim of the study is to describe the early rehabilitation process after wedge resection surgery secondary to bone tumor pulmonary mestasasis, highlightining the possible functional recovery in the short and medium term after surgery and indentifying the possible prognostic factors.

This is a single-center, prospective, observational and exploratory clinical study. The object of this study is to evaluate the accuracy of proteomics approaches on resected lymph node samples in evaluating lymph node metastasis status in cholangiocarcinoma patients.

The aim of the study is to establish a multi-center, retrospective database for patients with intramedullary spinal cord metastases (ISCM) and analyse the functional outcome in surgically treated ISCM patients. The hypothesis is that the surgical treatment of selected ISCM patients does not lead to persistent morbidity and does not increase mortality, compared to patients that are treated non-operatively. Secondary objectives are to assess pre- to postoperative neurological deficits, ambulatory status, and overall survival of surgically treated ISCM patients. The investigators intend to include a control cohort of patients with ISCM from participating centers, who underwent non-surgical oncological treatment (radiotherapy with or without chemotherapy). This control cohort of patients will be used to match patients with and without surgical treatment. Primary endpoint (analysed in surgically treated ISCM patients): Functional outcome at 90 days after treatment initiation, measured by the modified Japanese Orthopaedic Association (mJOA) scale. This is a score evaluating motor function of upper and lower extremities, sensory function of upper extremities and sphincter function / voidance. The mJOA ranges from 0 - 18 points, with higher score values representing better functional outcome. The minimum clinically important difference of the mJOA is 1-2 points, and scores lower than 14 indicate moderate myelopathy, scores lower than 11 indicate severe myelopathy. Secondary endpoints (analysed in surgically treated ISCM patients and analysed in matched patients with and without surgical treatment): Functional outcome (mJOA) at 6 and 12 months Ambulatory status and continence at 90 days, 6 & 12 months (determined by mJOA subscores) Neurological outcome, measured by American Spinal Cord Injury Association (ASIA) Impairment Scale at 90 days, 6 and 12 months Rate & type of complications at 90 days after treatment according to The Novel Therapy Disability-Neurology Grade (TDN grade)16 Overall survival (in days)
