Breast conservation as an additional benefit was beyond the initial expectations of the investigators who pioneered neoadjuvant chemotherapy (NACT). In recent years an increasing number of patients with locally advanced breast cancer (LABC) are being treated with NACT, followed by breast conservation surgery with axillary dissection and radiation as a part of the multimodality management. Breast conservation has not been the standard of care for women with LABC, owing to concerns of increased chances of local recurrence, and possible survival disadvantage and psychological trauma from experiencing a recurrence of malignancy. LABC is still a common form of presentation of breast cancer in developing countries. Strict adherence to treatment protocols and regular follow-ups for years may not be practical for a large majority of patients hailing from the regions most affected by LABC. Defaulters often thus have a heavy price to pay. Hence lies the importance of carefully selecting LABC patients for a breast conservation approach from others that would have a higher risk of locoregional recurrence. Can we extrapolate the lessons learnt in early breast cancer to LABC and offer selected patients with LABC breast conservation therapy? Would the local control and survival results with conservative therapy be comparable to those obtained using mastectomy, or does the increased tumor burden in LABC necessitate ablative surgery in all women? This review aims to address these important questions.
保乳作为一项额外的益处超出了开创新辅助化疗(NACT)的研究人员的最初预期。近年来,越来越多的局部晚期乳腺癌(LABC)患者接受NACT治疗,随后进行保乳手术加腋窝清扫及放疗,作为多模式治疗的一部分。由于担心局部复发几率增加、可能存在生存劣势以及恶性肿瘤复发带来的心理创伤,保乳尚未成为LABC女性患者治疗的标准方案。在发展中国家,LABC仍是乳腺癌常见的一种表现形式。对于大多数来自受LABC影响最严重地区的患者来说,严格遵守治疗方案并进行多年定期随访可能并不实际。因此,违约者往往要付出沉重代价。因此,从其他有更高局部区域复发风险的患者中仔细挑选适合保乳方法的LABC患者至关重要。我们能否将早期乳腺癌的经验教训推广到LABC,并为选定的LABC患者提供保乳治疗?保乳治疗的局部控制和生存结果能否与乳房切除术相媲美,或者LABC中增加的肿瘤负荷是否使所有女性都必须接受切除手术?本综述旨在回答这些重要问题。
