A quantum dot-based method for analysis of DNA methylation Among the earliest events that changes a standard cell right into a malignant one is recognized as deoxyribonucleic acid hypermethylation, a biochemical alteration that inactivates critical tumor-suppressor genes. A team of investigators at Johns Hopkins University is rolling out a quantum dot-based technique that can quantify DNA methylation in premalignant cells harvested from human being patients. Jeff Tza-Huei Wang, Ph.D., and Hetty E.We determined that 640 sufferers with 466 events would give a power of 89 percent to detect a hazard ratio of 0.74 for disease progression or loss of life in the elotuzumab group in the final evaluation. This interim evaluation was scheduled to become performed when at least 70 percent of the required events had been noticed and after the very least follow-up of 24 months. The alpha level for the evaluation of progression-free survival was calculated based on the occurrence of 384 of 466 events at the time of the interim analysis. An observed hazard ratio of 0.794 or less for disease progression or loss of life indicated a significant difference statistically.
