What is the difference between disease free survival and overall survival?
What is the difference between disease free survival and overall survival?
Unlike progression-free survival in the advanced cancer setting, which refers to time from treatment to disease progression (or death) in patients who already have measurable cancer in their bodies, DFS refers to time from treatment until the recurrence of disease (or death) after undergoing curative-intent treatment.
What is the difference between EFS and PFS?
PFS progression-free survival; EFS event-free survival; OS overall survival; RCTs randomized controlled trials; HR hazard ratio; CI confidence interval.
What is an overall survival event?
Listen to pronunciation. (oh-ver-AWL 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 patients diagnosed with the disease are still alive.

| A healthy person will be free of disease. | A disease-free person may or may not be healthy. |
What is the difference between PFS and DFS?
Disease free survival While PFS is used as a clinical endpoint for treatments that are used to manage more advanced, metastatic malignancies, DFS is used as a clinical endpoint for adjuvant treatments after definitive surgery or radiotherapy.
How is overall survival measured?
The overall survival rate is often stated as a five-year survival rate, which is the percentage of people in a study or treatment group who are alive five years after their diagnosis or the start of treatment.
What is EFS in clinical trials?
The measure of time after treatment that a group of people in a clinical trial has not had cancer come back or get worse. This term is also usually used in the context of scientific research.
How is overall survival reported?
Overall survival was estimated using the Kaplan-Meier method and compared between groups using a log-rank test and Cox proportional hazards regression adjusting for age, sex, race, education level, level of prior computer use, and primary cancer type.
What is overall survival rate?
Listen to pronunciation. (oh-ver-AWL ser-VY-vul rayt) The percentage of people in a study or treatment group who are still alive for a certain period of time after they were diagnosed with or started treatment for a disease, such as cancer.
