Chemotherapy is widely used in the management of patients with advanced bre
ast cancer. However, a considerable proportion of patients experience toxic
side effects without gaining benefit. This study aimed to elicit oncologis
ts' views of the goals of chemotherapy for patients with advanced breast ca
ncer and to elicit which factors are important in decisions to recommend ch
emotherapy to such patients. 30 oncologists underwent a semi-structured int
erview to examine their views of 5 goals of chemotherapy and of various dis
ease, treatment and patient-related factors that might influence decisions
to offer treatment. The clinicians also made decisions regarding treatment
in relation to a hypothetical patient scenario under varying clinical condi
tions. Relief of symptoms and improvement of activity were rated as the mos
t valuable and achievable goals of treatment. The patient's performance sta
tus, frailty and their wishes regarding treatment were the most important p
atient-related factors in determining decision-making. The most important d
isease/treatment-related factors were pace of the disease, previous poor re
sponse to chemotherapy co-existing symptoms and concurrent medical conditio
ns. The hypothetical scenario revealed that cc-existing medical conditions,
adverse previous response, increased age and depression would decrease the
likelihood of recommending chemotherapy, whereas key symptoms (e.g. breath
lessness) and the patient's goals would increase the likelihood. The findin
gs suggest that British oncologists primarily aim to improve patients' phys
ical function, although subjective factors, such as a patient's desire for
anti-cancer treatment and their future goals, also influence decisions to o
ffer treatment. (C) 2001 Cancer Research Campaign.
