Evaluation of eligibility and utilization of breast conservation treatment in an Asian context

Breast conservation treatment (BCT) has long been recognised to provide survival outcomes equivalent to mastectomy for the treatment of breast cancer. However, published reports of BCT rates in Asian communities are lower than those from Western countries. This study sought to investigate the eligibility and utilisation of BCT in a predominantly Asian population.

All patients treated surgically by a single surgeon at a private medical facility between 2009 and 2011 were included in the study. Patients were deemed to have successful BCT if they underwent breast conserving surgery with pathologic clear margins and completed all recommended adjuvant treatment. Those who did not complete adjuvant treatment were excluded from the analysis.

Data from a total of 161 patients who underwent treatment during the study period were analysed. The mean age was 48.8 years. One hundred and six patients (65.8%) were of Chinese ethnicity, 12 were Indian (7.5%), 11 were Malay (6.8%), 18 were Caucasian (11.2%) and 14 (8.7%) were of other Asian ethnicity. One hundred and thirty-eight women (85.7%) underwent BCT. Of the 23 (14.3%) who underwent mastectomy, 8 (5.4%) elected to undergo a mastectomy despite being eligible for BCT. In total, it was assessed that 146 of 161 patients (90.7%) were eligible for BCT and utilisation was 94.5%.

In this study, eligibility, utilisation of BCT and eventual successful breast conservation rates are similar to published rates in Western communities. Additional research is needed to investigate the reasons for the lower published BCT rates in Asian countries and determine ways to improve them.
