Active clinical trials for "Neoplasms"

Ocular myasthenia gravis (OMG) is an autoimmune neuromuscular disease mediated by pathogenic autoantibodies. Its etiology and pathogenesis are not completely clear. The occurrence and development of OMG are the result of the joint participation of genetic factors, environmental factors and immune factors. The role of infectious factors in the pathogenesis of autoimmune diseases is a hot topic in the international discussion.By analyzing the difference in the positive rate and titer of CMV antibodies between ocular myasthenia gravis and healthy people. By analyzing the correlation between the positive rate and titer of CMV antibodies and ocular myasthenia gravis clinical manifestations, acetylcholine receptor antibodies, ESR, hypersensitive C-reactive protein, complement C3, complement C4 and thymus status.To investigate the correlation between cytomegalovirus and ocular myasthenia gravis. It can provide new insights for further studies on the etiology and possible pathogenesis of ocular myasthenia gravis.

This study aims to describe the clinical outcomeand the radiological appearance of aneurysmal bone cyst treated by means of interventional radiology procedures (percutaneous sclerosis and endovascular embolization)

The study aims to explore the clinical utility of circulating tumour DNA (ctDNA) in assessing for alterations of anti-epidermal growth factor receptor (EGFR) primary resistance in RAS and BRAF wild-type metastatic colorectal cancer (CRC) patients treated with anti-EGFR monoclonal antibodies (cetuximab / panitumumab) in combination with fluorouracil (FU)-doublet chemotherapy.

The aim of this present study is to compare functional results and quality of life after sigmoidectomy for diverticulitis and sigmoid cancer.

The purpose of this study is to establish a standardized process for obtaining digital pathological image information of ocular tumors; use modern pathological techniques to obtain the co-expression information of multiple biomarkers in the pathological tissues of ocular tumors, and finally construct standardized digital ocular tumors with biomarkers Pathology image database.

Investigators will discuss the different surgical techniques for removal of spheno_orbital meningiomas with proptosis.investigators also will follow up the patient to know the outcome of removal of these tumours.

The investigators evaluate the response of rectal cancer to neoadjuvant therapy and classify the response according to specific periods of time after the end of neoadjuvant treatment.

Assessment of correlation between tumor deposits and clinicopathological characteristics of colorectal cancer. Detection of association between tumor deposits and stage of colorectal cancer. Evaluate the relationship between tumor deposits and prognosis of colorectal cancer patient.

Reconstruction using 3D virtual models has brought about a revolution in diagnostic imaging and its use is increasingly widespread. The objective of this work is to determine the precision of the 3D model when establishing the characteristics of tumors and their relationship with other anatomical structures.

This clinical trial is focused in the development of a screening test for the people at risk of colo-rectal cancer (aged more than 50 years old), valid and safe, improving the screening prognosis increasing the sensitivity and sensitive as compared with the current method, fecal occult blood.
