Clinical status,
relapse, metastasis and death in 2982 women with breast cancer.
Description
This dataset is a transformation of the example dataset used by Crowther
and Lambert in their multistate paper.
Usage
data(BrCa)
Format
A data frame with 2982 observations on the following 17 variables:
pidPerson-id; numeric
yearCalendar year of diagnosis
ageAge at diagnosis
menoMenopausal status; a factor with levels pre post
sizeTumour size; a factor with levels <=20 mm >20-50 mm >50 mm
gradeTumour grade; a factor with levels 2 3
nodesNumber of positive lymph nodes, a numeric vector
prProgesteron receptor level
pr.trTransformed progesteron level
erEstrogen receptor level
hormonHormon therapy at diagnosis; a factor with levels no yes
chemoChemotherapy treatment; a factor with levels no yes
torTime of relapse, years since diagnosis
tomTime of metastasis, years since diagnosis
todTime of death, years since diagnosis
toxTime of exit from study, years since diagnosis
xstVital status at exit; a factor with levels Alive Dead
Details
The dataset has been modified to contain the times (since diagnosis) of the events of
interest, to comply with the usual structure of data.
Source
The original data were extracted from:
http://fmwww.bc.edu/repec/bocode/m/multistate_example.dta, this
is modified representation of the same amount of information.
References
The data were used as example in the paper by Crowther and
Lambert: Parametric multistate survival models: Flexible
modelling allowing transition-specific distributions with application
to estimating clinically useful measures of effect differences; Stat
Med 36 (29), pp 4719-4742, 2017. (No, it is not the paper, just the
title.)
