Although immediate breast reconstruction is increasingly becoming popular worldwide, evidence from resource-limited settings is scarce. We investigated factors associated with immediate breast reconstruction in a multiethnic, middle- income Asian setting. Short-term surgical complications, timing of initiation of chemotherapy, and survival outcomes were compared between women undergoing mastectomy alone and their counterparts receiving immediate breast reconstruction. Methods: This historical cohort study included women who underwent mastectomy after diagnosis with stage 0 to stage IIIa breast cancer from 2011 to 2015 in a tertiary hospital. Multivariable regression analyses were used to assess factors associated with immediate breast reconstruction and to measure clinical outcomes. Result: Out of 790 patients with early breast cancer who had undergone mastectomy, only 68 (8.6%) received immediate breast reconstruction. Immediate breast reconstruction was independently associated with younger age at diagnosis, recent calendar years, Chinese ethnicity, higher education level, and invasive ductal carcinomas. Although immediate breast reconstruction was associated with a higher risk of short-term local surgical complications (adjusted odds ratio: 3.58 95% confidence interval 1.75 -7.30]), there were no significant differences in terms of delay in initiation of chemotherapy, 5-year disease-free survival, and 5-year overall survival between both groups in the multivariable analyses. Conclusion: Although associated with short-term surgical complications, immediate breast reconstruction after mastectomy does not appear to be associated with delays in initiation of chemotherapy, recurrence, or mortality after breast cancer. These findings are valuable in facilitating shared surgical decision-making, improving access to immediate breast reconstruction, and setting priorities for surgical trainings in middle-income settings.
