This paper analyses doctor-patient interaction at the outpatients consultat
ions of a Medical Oncology Service in a Spanish public hospital. First, it
introduces the cultural and institutional setting of the research. It then
describes some details of the sequential organisation of the routine encoun
ters between patients undertaking chemotherapy and their doctors. Three con
ventionalised doctors' utterances ('How are you','How are you tolerating th
e treatment', and 'The tests are fine') are shown to he crucial for assessm
ent and treatment activities. It then discusses how the use of these tokens
affects the dimension of casual/institutional talk, and doctor-patient int
eractional asymmetry. The analysis pays special attention to the way in whi
ch treatment decisions are grounded in and projected by the assessment acti
vities in the encounter. The discussion considers how the interactive resou
rces deployed in the consultation relate to the incorporation of patients'
views in routine decisions.
