Colorectal cancer (CRC), as one of the most common gastrointestinal malignancy, is original from the epithelial/endothelial cells of colorectal tissues. CRC is one of the highest incidence and mortality rates of any malignancy in humans today. Moving forward the early diagnosis window of colorectal cancer, dynamic monitoring of the risk of postoperative recurrence and metastasis, early intervention is of great value in improving the diagnosis and treatment outcome of colorectal cancer. The clinical diagnosis of CRC via circulating tumor cells (CTC) has been considered as one of the fast, noninvasive, reproducible liquid biopsy methods, and it has been widely used in the early diagnosis, treatment monitoring and prognosis evaluation of colorectal cancer. This review systematically expounded the applied research values of CTC counting, protein expression (phosphatase of regenerating liver-3, matrix metalloproteinase, etc), molecular characterization (adenomatous polyp of colon, erb-b2 receptor tyrosine kinase, etc), mRNA expression profile and single cell sequencing in the diagnosis and treatment of colorectal cancer, in order to assist clinical in rational use of CTC monitoring indicators and provide support for improving the prognosis of colorectal cancer.

Objective To investigate the characteristics and essential points of diagnosis and treatment of double trisomy 47,XXX/48,XXX,+8 combined Behcet disease, a rare inherited immunodeficiency disorder. Methods The clinical manifestations, karyotype analysis and gene test results of the patients were analyzed, and relevant literatures were reviewed. Results A 11-year-old girl presented repeated fever for more than 6 years, accompanied with recurrent genital herpes infection and oral apthosis, was clinically diagnosed with Behcet disease. Cytogentic and molecular karyotyping on peripheral lymphocytes demonstrated 47,XXX[12]/48,XXX,+8[18]. Conclusions Conventional karyotype analysis and chromosomal microarray analysis have a complementary role in the diagnosis of the disease. We conclude that patients with constitutional trisomy 8 and those with trisomy 8 confined to the bone marrow are both at increased risk of developing features of Behcet disease. The mechanism may relate to increased gene dosage of candidate genes for Behcet's disease on chromosome 8.
