RESUMO
Uveal melanoma (UM) is the most common intraocular malignancy in adults. Recently, great progresses have been made in the diagnosis, treatment and prognosis of UM, however, nearly 50% of patients still develop liver metastases, which severely affects on the survival of UM patients. Whether UM patients will benefit from the immune checkpoint blockade similarly as the cutaneous melanoma (CM)? Whether the specific gene mutations targeting UM could improve the anti-tumor efficacy? Whether chimeric antigen receptor T cell or T cell receptor T cell immunotherapy is effective to UM patients with liver metastases? How about the combinational therapies in UM and the clinical effects? This review summarizes the anti-tumor research and novel treatment options of UM, analyzes the current achievements and problems.
RESUMO
OBJECTIVE@#To diagnose and fine map a deletion in chromosome region 2q37.@*METHODS@#G-banded chromosomal karyotyping, multiplex ligation-dependent probe amplification (MLPA), single nucleotide polymorphism array (SNP-array), and fluorescence in situ hybridization (FISH) were carried out in conjunct for the analysis.@*RESULTS@#The patient was found to have karyotype of 46,XY,del(2)(q3?), MLPA revealed one copy number of both CAPN10-3 and ATG4B-7 genes from the 2q37.3 region, Both parents were found to be normal upon chromosome karyotyping and MLPA. SNP-array has found a 9.7 Mb deletion in the 2q37.1.37.3 region. FISH analysis has confirmed there is a single copy for 2q37.3.@*CONCLUSION@#Combination of MLPA, FISH and SNP-array have enabled accurate diagnosis for the patient, and also provided more clues for the correlation of genotype with the phenotype of the disease, and a basis for genetic counseling.
