RESUMO
Prostate cancer has become the most common malignant disease in male. Due to development of therapy methods, the overall survive rate of advanced prostate cancer has been improved significantly. The demands for higher quality of life are impending in advanced prostate cancer patient. With the progression of prostate cancer, about 1/3 to 2/3 of patients will suffer from moderate to severe lower urinary tract symptoms. Severe lower urinary tract symptoms can lead to negative effects on treatment and quality of life. However, there is no standard treatment for lower urinary tract symptoms in advanced prostate cancer patients. This article reviews the clinical application of palliative transurethral resection of prostate in patients with advanced prostate cancer.
RESUMO
Congenital vertebral malformation (CVM) is a congenital vertebral structural deformity caused by abnormal somitogenesis during embryonic development, of which the reason lies in gene mutation or abnormal regulation of the genes that coordinate somitogenesis during embryonic period. ICVAS had proposed a new classification algorithm for CVM, which facilitated exploration for its genetic etiology. Genomic Copy Number Variation (CNV) is a kind of DNA mutation, which is important for human evolution, phenotype polymorphism and diseases. Series of advances have been made on genetic causes of CVM, especially on CVM caused by CNV. CNVs of chromosome 16p11.2, 10q24.31, 17p11.2, 20p11, 22q11.2 and a few other regions are associated with CVM, indicating that gene dosage may play important roles in the development of the spinal cord.
