Can median overall survival be longer than median follow-up?
At this analysis the median OS (1130 days) exceeded the median follow-up time (867 days). In the most recent two analyses of the data (March 8, 2019 and May 20, 2019), the median OS settled at a consistent value (880 days) that did not exceed the median follow-up times (1023 days and 1096 days, respectively).
What is median survival?
Listen to pronunciation. (MEE-dee-un ser-VY-vul) The length of time from either the date of diagnosis or the start of treatment for a disease, such as cancer, that half of the patients in a group of patients diagnosed with the disease are still alive.
Which is the best definition of median survival?
Median survival is a statistic that refers to how long patients survive with a disease in general or after a certain treatment. It is the time — expressed in months or years — when half the patients are expected to be alive. It means that the chance of surviving beyond that time is 50 percent.
What are the results of disease free survival?
Early disease-free survival (DFS) results from the ABCSG-18 study suggest a benefit on disease recurrence with an absolute decrease in events of 2.1% at 5 years compared to placebo.
What’s the probability of progression free survival ( OS )?
Using preset 6- and 9-month medians for PFS in each arm of a hypothetical two-arm study, they concluded that a statistically significant increase in OS was detected with 90 percent probability if median SPP was 2 months, but less than 20 percent if median SPP was 24 months.
What does the median survival rate in MS mean?
Basics of Median Survival (MS) Median survival is a statistic that refers to how long patients survive with a disease in general or after a certain treatment. It is the time—expressed in months or years—when half the patients are expected to be alive. It means that the chance of surviving beyond that time is 50 percent.
