Active clinical trials for "Neoplasm Metastasis"

Luminal A breast cancer is a kind of breast cancer with low rate lymph node metastasis and good survival. But in clinical practice, Luminal A breast cancer can present with early, unexpected lymph node metastasis some time, indicates poor survival. Silent information regulator 2 homolog 1 (SIRT1) plays a different role in breast cancer with different molecular typing. Previous study supports a role of SIRT1 protein as tumor suppressor in Luminal A breast cancer, in association with apoptosis-related proteins. The epithelial-to-mesenchymal transition(EMT) process results in loss of cell-cell adhesion, increased cell mobility, and is crucial for enabling the metastasis of cancer cells. But no similar study in Luminal A breast cancer. Hence, this study will 1) investigate the expression pattern of SIRT1 in primary tumor and lymph node metastasis; 2) investigate the different expression pattern of SIRT1 in T2/T3 , lymph node negative tumor and T1, lymph node positive tumor; 3) investigate potential role of SIRT1 enzyme in regulating cell migration and invasion in Luminal A breast cancer cells.

Pancreatic metastases are a rare entity. In cases of metastatic renal carcinoma (RCC) it can present as isolated pancreatic metastasis, considering the possibility of surgical resection. Goals: Define survival after resection of pancreatic cancer metastases renal in a wide range of our country. Identify predictive survival factors Methods: Retrospective multicenter study in which cases of pancreatic resection due to renal cancer metastases.

More than 50% of intestinal NETs are metastatic at the time of diagnosis, the liver being the main affected organ in 50-90% of cases. Initial liver tumor burden and slope of the tumor growth rate are two major prognostic factors in patients with intestinal NETs, followed by tumor grade at pathology. They are used in routine practice by oncologists to adapt patient treatment. Unlike other tumors, most NETs metastases are slow-growing tumors. Previous studies have shown that approximately half of the patients diagnosed with liver metastases showed no progression over a period of 3 to 6 months. The aim of this non randomised retrospective cohort study is to investigate whether the volumetric monitoring of the total tumor burden compared to the RECIST 1.1 criteria (used in routine practice by radiologists) at baseline and early follow-up (3 to 6 months) is more suitable for NETs, making possible to predict the prognosis at the onset of the disease, and also allowing a better adaptation of the treatment. The secondary objectives are to evaluate if the initial volume of the liver tumor is a prognostic factor of time to progression, to correlate the initial liver tumor volume and the number of liver lesions to the blood concentration of Chromogranin A (CgA), the presence of extra-abdominal disease and to correlate the tumor growth rate (TGR) and KI 67 (%) at base-line.

Primary immunodeficiencies (PID) represent more than 150 diseases affecting the immune system. More than 50% of PIDs are due to a lack or an insufficiency in antibody production. Some of these immunodeficiencies as well as some secondary immune deficiency with deficient antibody production (especially in hematology and oncology) are responsible for repeated and/or severe infections, requiring long-term replacement therapy with intravenous polyclonal immunoglobulin. Intravenous replacement therapy is administered every 21 or 28 days in hospital. Subcutaneous administration (weekly or bi-weekly) can be initiated for patients who cannot tolerate intravenous infusions or who have difficult venous access. However, some patients experience a decrease in quality of life with these more frequent administration at home. A new treatment is available in France since 2017, which is a subcutaneous infusion of human immunoglobulin facilitated by recombinant human hyaluronidase (IGHy), administered every 3 to 4 weeks in a single abdominal site, at home. No direct data are available in adults to evaluate tolerance and satisfaction with this treatment, but we know it is a preferred option in children and adolescents.

Early gastric cancer is defined as gastric cancer that only invades mucosal or submucosal layer. The 5-year survival rate of gastric cancer can exceed 90% due to appropriate treatment. The most important consideration is whether there is lymph node metastasis. Preoperative examination including gastroscopy, endoscopic ultrasonography (EUS) and CT are not accurate enough to predict lymph node metastasis in early gastric cancer. In a retrospective study, we created a nomogram to predict lymph node metastasis in early gastric cancer. In prospective validation, the sensitivity and specificity of the nomogram was 75% and 91%, respectively. Sentinel lymph node is a promising concept in early gastric cancer. Using carbon nanoparticles as tracer, the sensitivity and specificity of sentinel lymph node predicting lymph node metastasis in early gastric cancer were 90% and 100%. Based on these results, we proposed a new method that combines the Nomogram and sentinel lymph node to predict lymph node metastasis in early gastric cancer. First, the probability of lymph node metastasis of early gastric cancer patients is calculated by the Nomogram. Those with low incidence of lymph node metastasis continue to the sentinel lymph node procedure. A patient will be considered non lymph node metastasis if his/her frozen pathology of the sentinel lymph nodes is negative during the surgery. Then the standard radical gastrectomy is performed with lymphadenectomy. By comparing postoperative pathology and sentinel lymph node frozen pathology, the specificity of Nomogram combining sentinel lymph node predicting lymph node metastasis in early gastric patients is calculated. The primary endpoint of this research is that the specificity of the above-mentioned method is over 95%.

This study proposes to establish a CT radiomics-based prediction model for identifying metastasis of each station lymph nodes in gastric cancer.

Axillary lymph node status is a vital prognostic factors in breast cancer patients and provides crucial information for making treatment decisions.This projective observational study is planned to identify risk factors for axillary metastases in breast cancer patients with axillary ultrasound and to construct a nomogram to predict the risk of axillary metastases in these patients.

The purpose of this study is to learn whether our own made predictive algorithm can be used as a clinical practical decision support for patients with NSCLC spinal metastasis. The scoring system consists of the use of EGFR-TKI, KPS, Age, SCC, CA125 and smoking history. By predicting survival doctors could determine which patients are suitable for palliative therapy.

The aim of the study is to assess the value of contrast enhanced ultrasound in the evaluation of de novo focal liver lesions in clinical practice, in a prospective multi-center design.

The purpose of this prospective multicenter trial is to investigate the value of molecular markers in endometrial cancer for predicting lymph node metastasis and prognosis in relation to treatment.
