Active clinical trials for "Neoplasm Metastasis"

To investigate the value of CTCs and ctDNA in the diagnosis of metastasis in ascites/peritoneal flushing fluid and blood; To investigate the influence of laparoscopic CO2 pneumoperitoneum establishment on peritoneal and hematogenous metastasis of advanced gastric cancer; To explore the influence of the number and type of CTCs and ctDNA on metastasis and prognosis.

Accumulating evidence indicates that patient- derived organoids (PDOs) can predict drug responses in the clinic. Metastasis is the main cause of death in colorectal cancer patients, and the treatment of patients with liver metastasis remains poor. Tumor heterogeneity is the cause of treatment failure. In this study, we aim the investigate the consistency of drug sensitivity for the matched primary and metastatic tumor in patients with liver metastasis.

This is a one-stage single-arm phase II clinical trial designed to prospectively test the survival prediction tool as developed by Lee et al on patients referred to radiation oncology for palliative treatments. Survival prediction score based on objective data including laboratory values, attendance to emergency room, and primary cancer origin will be assigned to each patient at time of enrollment.

This is a clinical trial from Eastern Cooperative Thoracic Oncology Project (ECTOP), numbered as ECTOP-1010. Anatomical Location and Metastasis Pattern of Intrapulmonary Lymph Nodes (Group 11-13) in Non-small Cell Lung Cancer: a Multi-center, Prospective observational Clinical Trial

The therapeutic regimens of adjuvant and neoadjuvant chemotherapy for colorectal cancer (CRC) remain largely relied on clinical experience, and thus preclinical models are needed to guide individualized medicine. The investigators are going to establish 3D bioprinted CRC models and organoids from surgically resected tumor tissues of CRC patients with or without liver metastases. In vitro 3D models and organoids will be treated with the same chemotherapy drugs with the corresponding patients from whom the models are derived. The sensitivity of chemotherapy drugs will be tested in these two types of in vitro models, and the actual response to chemotherapy in patients will be evaluated. The predictive ability of 3D models for chemotherapy sensitivity in CRC patients will be compared with that of the organoids. This observational study will validate the potential value of 3D bioprinted tumor models in predicting the response to chemotherapy in CRC.

Currently, therapeutic options in BRAF mutated melanoma with brain metastasis occurring after achievement of a good control of extracerebral secondary lesions by a first line combined targeted therapy (TT) are limited. In this setting, the addition of an anti PD1 agent to TT may be proposed as a second line strategy. This observational survey aims at investigating the benefit/risk ratio of this triple combination in a small cohort of patients.

The study authors hypothesize that in patients with intestinal polyps, tumor cells could disseminate and circulating factors could be secreted by the polyp. These two parameters could become biomarkers to refine the follow-up of patients and to establish targeted therapeutic strategies.

This is a prospective, observational diagnostic study aiming to assess multiparametric MRI-based clinico-radiomics for identifying lymph node metastasis status in hilar cholangiocarcinoma.

The purpose of this study is to evaluate the performance of a PET/CT-based deep learning signature for predicting occult nodal metastasis of clinical stage N0 non-small cell lung cancer in a multicenter prospective cohort.

The investigators will perform integrative analysis of CRC liver metastasis
