Objectives:to determine the quality of life and anxiety in patients with breast cancer and
the changes they experience after treatments. Method:prospective study. Breast cancer statistics (n=339, confidence=95%, accuracy= ±
5.32%). The quality of life questionnaires (QLQ) used were QLQ C-30 and QLQ Br23,
and the State-Trait Anxiety Inventory (STAI) was used for anxiety. A multivariate
analysis was performed to identify variables associated with baseline quality of
life and anxiety as well as pre- and post-treatment differences. Authorization was
obtained from the Ethics Committee, and informed consent was provided by all
patients. Results:the baseline quality of life dimensions with the lowest score were future
prospects (46.0/100) and sexual enjoyment (55.7/100). The dimensions with the
highest score were body image (94.2/100) and role (93.3/100). The most disturbing
symptoms were insomnia, fatigue and concern about hair loss. After treatment, the
dimensions of physical function, role, body image, financial concerns and
symptomatology worsened, whereas emotional function and future prospects improved.
Severe anxiety presented as a state (48.6%) and as a trait (18.2%). The highest
baseline state anxiety was associated with married-widowed status and anxiolytic
medication. The greatest trait anxiety was associated with an inactive work
situation, anxiolytic medication, breast swelling and advanced stage at diagnosis.
After treatment, anxiety significantly decreased. Conclusions:After treatment, the quality of life score was positively modified, while state
and trait anxiety decreased.
