Natural history of 1341 sequential patients with monoclonal
gammopathy of undetermined significance (MGUS). This is a superset of
mgus data, at a later point in the accrual process
mgus2 data(cancer, package="survival")
A data frame with 1384 observations on the following 10 variables.
age at diagnosis, in years
a factor with levels
year of diagnosis
size of the monoclonal serum splike
time until progression to a plasma cell malignancy (PCM) or last contact, in months
occurrence of PCM: 0=no, 1=yes
time until death or last contact, in months
occurrence of death: 0=no, 1=yes
This is an extension of the study found in the
