Progression-free survival (PFS) is "the length of time during and after the treatment of a disease, such as cancer, that a patient lives with the disease but it does not get worse". [1] In oncology , PFS usually refers to situations in which a tumor is present, as demonstrated by laboratory testing, radiologic testing, or clinically.
Physical activity before cancer diagnosis is associated with a decreased risk of cancer progression and death, a new study, ... Throughout the observed time frame, almost 19% of the participants ...
The Progression Free Survival is usually used in analysing the results of the treatment for the advanced disease. The event for the progression free survival is that the disease gets worse or progresses, or the patient dies from any cause. Time to Progression is a similar endpoint that ignores patients who die before the disease progresses.
The x axis is time, from zero (when observation began) to the last observed time point. The y axis is the proportion of subjects surviving. At time zero, 100% of the subjects are alive without an event. The solid line (similar to a staircase) shows the progression of event occurrences. A vertical drop indicates an event.
Patients with a global deterioration of health status requiring discontinuation of treatment without objective evidence of disease progression at that time should be classified as having “symptomatic deterioration”. Every effort should be made to document the objective progression even after discontinuation of treatment.
Periodization can apply different load progression strategies depending on individual fitness goals. Periodization in the context of fitness or strength training programs means scheduling for adequate recovery time between training sessions, and for variety over the course of a long-term program.
Radioembolization with 90 Y significantly prolongs time-to-progression (TTP) of HCC, [13] has a tolerable adverse event profile, and improves patient quality of life more than do similar therapies. [14] 90 Y has also found uses in tumor diagnosis by imaging the Bremsstrahlung radiation released by the microspheres. [15]
