Active clinical trials for "Neoplasm Metastasis"

Ultrastructural analysis of trabeculectomy specimens of patients with uveitic secondary glaucoma. To evaluate morphological changes and to compare to primary open angle glaucoma patients.

The purpose is to characterize tumour biological markers in brain metastases tissue from patients with different primary tumour by using ex vivo techniques as high-resolution magic angle spinning MR spectroscopy and micro array.

Our study established a model combine the in silico biology and empirical methods to identify clinically useful biomarker from information of microarray gene expression profiles in public domain. Through this method, we found trophinin as a novel prognostic marker for early stage lung cancer, which provide insight towards the process of cancer metastasis and the potential target for treatment.

Hypothesis: the pattern of MRI contrast enhancement after gadolinium injection is different in tumors that respond well to gamma knife. We are going to acquire sequential T1-weighted images of brain lesions before, during and after injection of Gd-DTPA. This will be repeated before and after a treatment with gamma knife. We will then analyse our results to see if there are common enhancement characteristics between lesions that will respond well to the radiosurgery treatment. Response will be clinically assessed by tumor volume as determined by MRI approximately 4 to 6 months after treatment.

The investigator developed this protocol to accurately assess lymph node response to neoadjuvant chemotherapy in clinical stage N1 (cN1) breast cancer patients. Accuracy of sentinel lymph node biopsy (SLNB) alone and in combination with the removal of wire-localized-clip-marked nodes will be analyzed. New model to predict lymph node pathological complete remission (pCR) so as to safely avoid axillary lymph node dissection in cN1 breast cancer patients is sought for.

Epidemiological, prospective and multicenter study to evaluate the utility of the BOMET-QoL questionnaire in patients with breast cancer (BC) and bone metastases (BM).

To establish a predicting system on axillary lymph node metastasis based on peripheral blood CK19mRNA and contrast-enhanced ultrasound.

The purpose of this study is to retrospectively collect and analyse the characteristics of breast cancer patients with bone metastasis, and compare the impact of intensive follow-up with standard post-operative surveillance on survival of Chinese breast cancer patients.

The purpose is to evaluate if sodium fluoride PET in patients having already undergone a choline PET negative for bone extension (non-metastatic status) modifies the status of patients concerning the existence or not of bone metastases. Secondary purposes are: To evaluate if detection of bone metastasis by sodium fluoride PET, not detected by choline PET, leads to change of treatment To evaluate inter-technique concordance (choline vs sodium fluoride PET) of results (metastatic status and number of lesions) To evaluate the inter-judge concordance of interpretation of sodium fluoride PET To study the discordance of metastatic status of 2 techniques.

To compare the surgical outcomes of treating phacoemulsification with intraocular lens implantation combined with goniosynechialysis (Phaco-IOL-GSL) associated malignant glaucoma (MG), using different incision sites in anterior vitrectomy combined with hyaloidotomy, zonulectomy, and iridectomy (VHZI).
