Objective: To determine if health-related quality-of-life (QOL) differences existed between breast cancer (BC) survivors receiving mastectomy and those receiving breast-conserving treatment (BCT). Factors associated with QOL in long-term BC survivors were also identified.
Methods: One hundred patients who had previously undergone BC surgery and were alive without recurrence for >5 years were asked to answer the patient-administered questionnaires to assess their QOL (Functional Assessment of Cancer Therapy scale-Breast: FACT-B) and psychological distress (Hospital Anxiety and Depression Scale: HADS). Of them, 93 responded to the questionnaires affirmatively.
Results: Although none of the QOL scores were related to the surgical procedures, statistically significant relationships were found between age and the scores of FACT-General and social/family well-being (SWB), and between the educational status and scores of SWB in univariate analyses. There was no statistically significant relationship between psychological distress and each factor examined. In multivariate analyses, significant correlations were established between scores of the FACT-BC subscale (FACT-BCS) and the type of surgery and between those on the FACT SWB subscale and age at study or educational status. Namely, patients who had undergone BCT, younger patients and patients with higher educational background scored higher QOL.
Conclusions: Among the BC survivors, those who underwent BCT experienced significantly but slightly better QOL than those who received mastectomy in FACT-BCS assessments. Younger patients and patients with higher educational backgrounds experienced significantly better SWB.
