Studies have shown Baux score to be effective in measuring comparative severity of burn injuries, and in predicting the prognosis for the patient. The modified version, which includes inhalation injuries, is more accurate than the original method, although neither method is as accurate as more complex calculated scores using advanced computer ...
Survival rate is a part of survival analysis.It is the proportion of people in a study or treatment group still alive at a given period of time after diagnosis. It is a method of describing prognosis in certain disease conditions, and can be used for the assessment of standards of therapy.
The five-year survival rate is a type of survival rate for estimating the prognosis of a particular disease, normally calculated from the point of diagnosis. [1] Lead time bias from earlier diagnosis can affect interpretation of the five-year survival rate.
Overexpression of the BCL2 gene (33% of cases) whose product, BcL2, inhibits apoptosis (i.e. programmed cell death) to thereby increase cell survival. "Double expresser lymphomas", i.e. those lymphomas with neoplastic cells that overexpress both Myc and Bcl2, are associated with a poor prognosis in PCDLBCL, LT. [3]
Lead time bias happens when survival time appears longer because diagnosis was done earlier (for instance, by screening), irrespective of whether the patient lived longer. Lead time is the duration of time between the detection of a disease (by screening or based on new experimental criteria) and its usual clinical presentation and diagnosis ...
The authors concluded that trials using a patient mix weighted toward good prognosis will not find such a difference. In 1993, a retrospective analysis was performed on 2031 patients with aggressive non-Hodgkin's lymphoma, of all ages, treated with a doxorubicin -based chemotherapy regimen such as CHOP between 1982 and 1987.

Survival rates for most childhood cancers have improved, with a notable improvement in acute lymphoblastic leukemia (the most common childhood cancer). Due to improved treatment, the 5-year survival rate for acute lymphoblastic leukemia has increased from less than 10% in the 1960s to about 90% during the time period 2003-2009.
An example of a Kaplan–Meier plot for two conditions associated with patient survival. The Kaplan–Meier estimator, [1] [2] also known as the product limit estimator, is a non-parametric statistic used to estimate the survival function from lifetime data.
