Chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) is one of the most frequent types of leukemia/lymphoma in adults in Western countries. However, there are few studies regarding its epidemiol. and treatment patterns in Asian countries. To investigate CLL/SLL in Asian populations, we identified CLL/SLL patients diagnosed during 2006 to 2015 from the Taiwan Cancer Registry Database and estimated the incidence. Further, patients diagnosed during 2008 to 2015 were included for the anal. of treatment patterns and survivals. Treatments for CLL/SLL were retrieved from the Taiwan’s National Health Insurance Research Database and survival data from the National Death Registry. In total, 1497 patients who were older than 20 years and had newly diagnosed CLL/SLL during 2006-2015 were identified. The age-standardized incidence rates of CLL/SLL (0.36 per 100 000 persons in 2006, and 0.54 in 2015) increased during the 10-yr period. The sex ratio was ranged from 1.21 to 2.63 with male predominant during 2006 and 2015. For the anal. of treatment patterns (n = 1236), 72.8% patients received chemotherapies. The median duration between the diagnosis and start of treatments was 27 days, and monotherapy of chlorambucil, bendamustine or cyclophosphamide was the most common regimen in initial treatments. The median follow-up duration for the patients receiving therapies was 29.6 mo, and 45.0% patients experienced relapse or refractory. In patients with relapse/refractory CLL/SLL, 34.1% received rituximab-containing chemotherapies. Three hundred and ninety-nine (32.3%) patients received intensive treatments, and 175 (43.9%) of them received rituximab-containing chemotherapies. The 5-yr overall survival (OS) rate was 61%, and age was an important prognostic factor for CLL/SLL patients. This study is the first population-based study in Asia and provides comprehensive evidence of epidemiol., treatment patterns and survivals of CLL/SLL in an Asian population. This study involved multiple reactions and reactants, such as 4-(5-(Bis(2-chloroethyl)amino)-1-methyl-1H-benzo[d]imidazol-2-yl)butanoic acid (cas: 16506-27-7Application In Synthesis of 4-(5-(Bis(2-chloroethyl)amino)-1-methyl-1H-benzo[d]imidazol-2-yl)butanoic acid).
4-(5-(Bis(2-chloroethyl)amino)-1-methyl-1H-benzo[d]imidazol-2-yl)butanoic acid (cas: 16506-27-7) belongs to imidazole derivatives. The solubility of imidazoles in ethers is lower than that in alcohols and decreases with increasing chain length of the ethers . In contrast, the solubility of benzimidazoles in alcohols (C3–C6) is higher than in water and generally decreases with a Imidazole derivatives have antibacterial, antifungal and anticancer functionality. It interacts with DNA and also binds to protein and stops cell division.Application In Synthesis of 4-(5-(Bis(2-chloroethyl)amino)-1-methyl-1H-benzo[d]imidazol-2-yl)butanoic acid
