Oncoplastic breast volume replacement with the use of lateral intercostal artery perforator flap

Breast cancer is very common, and there has been a lot of progress in terms of diagnosing and treating it. Surgical intervention, which is tailored to the patient's particular needs and numerous clinical concerns, is one of the management methods used. Some indicators that can be used are, for instance, the size and the stage. Smaller and earlier stage malignancies can be treated with a wide excision. However, getting a proper excision margin around the tumor and not removing too much tissue is problematic. Several studies have shown that when 20% of the breast volume is removed, there is a significant risk of deformity. Currently, oncoplastic surgery is the gold standard for breast reconstruction to minimize such a risk, and one of the techniques is volume replacement, which includes reconstruction of the breast with the transposition of tissue from elsewhere. Numerous volume replacement procedures were performed in the reported patients. The thoracodorsal artery perforator (TDAP) and lateral intercostal artery perforator (LICAP) flaps showed good outcomes in terms of cosmetic and oncological aspects, yet LICAP was found to be an excellent choice for the lateral breast defect and the aesthetic result was satisfactory. We present the case of a 19-year-old woman who had a borderline phyllodes tumor and 49-year-old woman with invasive breast cancer ductal carcinoma in situ (DCIS) that was treated with a wide excision and volume replacement with a LICAP. Following the success of the LICAP treatment, the defect appears symmetrical with the contralateral breast a few weeks following surgery. In conclusion, LICAP and TDAP flaps oncoplastic surgery offer advantages that should be considered to increase satisfactory of the patients after breast construction surgery in Indonesia.
