Filter by:Rare diseases generally refer to diseases whose prevalence rate is lower than 1 / 10 000 and the number of patients is less than 140000. Rare diseases are generally faced with the dilemma of a lack of qualified doctors, difficulty in large-scale screening, and a lack of rapid and effective channels for medical treatment. Studies have shown that 42% of patients say they have been misdiagnosed, and each patient with a rare disease needs to go through an average of eight doctors in seven years to see a corresponding rare disease specialist. More importantly, most rare diseases seriously affect the health and quality of life of patients. The ocular surface malignant tumor is a typical rare disease, and its incidence is less than 1 / 100000. The ocular surface not only affects the patient's appearance, but also damages the visual function, and the malignant tumor may even affect life. These uncommon malignant tumors are often hidden in the common black nevus on the eye surface, which is easy to be ignored and has great potential risks. With the improvement of people's living standards, people start to pay attention to rare diseases. In recent years, the rapid development of digital technology has also provided new opportunities for the prevention and treatment of rare diseases. Our team established the database of rare ophthalmopathy in China in the early stage, which provided a solid foundation for the digitization of precious clinical data. This study intends to develop an intelligent screening system for ocular surface malignant tumors, using the mobile phone for real-world verification and scale screening, and explore it to improve the ability of doctors to diagnose and treat rare diseases. This study is expected to improve the ability to screen malignant tumors on the ocular surface and provide a novel model for the universal screening of rare diseases.
A prospective study was performed on 8 eyes of 8 patients who underwent amniotic membrane graft after diffuse conjunctival squamous cell neoplasia excision followed by topical mitomycin C 0.04% eye drop between March 2014 and January 2018.
RATIONALE: Vaccine therapy may help the body build an effective immune response to kill tumor cells. PURPOSE: This randomized clinical trial is studying how well vaccine therapy works in treating patients with advanced melanoma.
RATIONALE: Lenalidomide may stop the growth of tumor cells by blocking blood flow to the tumor. Sunitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving lenalidomide together with sunitinib and low doses of cyclophosphamide once a day may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving lenalidomide together with sunitinib and cyclophosphamide works in treating patients with stage IV eye melanoma.
RATIONALE: Vaccines made from peptides may help the body build an effective immune response to kill tumor cells. Giving vaccine therapy together with GM-CSF, CpG 7909, and incomplete Freund's adjuvant may make a stronger immune response and kill more tumor cells. PURPOSE: This clinical trial is studying the side effects and how well vaccine therapy works in treating patients with recurrent stage III or stage IV melanoma that cannot be removed by surgery.
The purpose of this study is to test the safety and tolerability of subconjunctival injection of ranibizumab in the treatment of malignant conjunctival neoplasia using the incidence and severity of adverse events. Our secondary objective is to assess the efficacy of ranibizumab treatment on malignant conjunctival neoplasia by evaluating tumor destruction or reduction as documented by slit-lamp photography and ultrasonographic imaging and the regression of blood vessels.
