Surgery is the recommended treatment for breast cancer, the most common cancer in women in Taiwan and the leading cause of cancer-related deaths. Although breast-conserving surgery (BCS) has good prognosis, in some cases, BCS may cause more significant deformities and interfere with the patient’s psychosocial well-being. Oncoplastic breast surgery (OBS) is the treatment option in these cases.
OBS was first described in the 1990s. OBS is composed of partial mastectomy with oncoplastic methods (volume displacement/VD or volume replacement/VR) to decrease possible deformity or distortion of the nipple-areolar complex after surgery and adjuvant RT. During the past decades, several classifications of OBS have been published, but there is still no consensus on the use of oncoplastic surgery in different situations (based on the patient’s breast volume and tumor size). Therefore, based on the previous classification, we proposed our own algorithm to offer different reconstruction methods to achieve better esthetic outcomes based on the tumor-to-breast ratio.
