Inflammatory breast cancer (IBC) is a rare but aggressive subtype of breast cancer that has a propensity for locoregional recurrence and distant metastasis and is associated with a disproportionately high percentage of breast cancer deaths. IBC is not resectable at initial diagnosis and trimodality therapy is considered the standard treatment for IBC. This includes systemic therapy upfront, followed by modified radical mastectomy and comprehensive chest wall and regional node radiation. Despite this aggressive multi-modal treatment strategy, the prognosis remains worse in IBC when compared with non-inflammatory locally advanced breast cancers. For patients presenting with de novo stage IV IBC, treatment recommendations vary depending on tumor burden, cancer subtype, and presence of comorbidities. Efforts to improve outcomes in IBC are currently underway; however, progress has been affected by the low incidence of disease and limited number of dedicated studies in this population. Improvements in systemic therapies in breast cancer in general are likely to lead to improvements in IBC as well. More dedicated trials are needed to identify additional treatment strategies that may help to improve prognosis for these patients. Additionally, better frameworks for diagnosis, risk stratification based upon factors such as molecular subtype and response to neoadjuvant therapy, will be important to make further progress in IBC.
炎性乳腺癌(IBC)是一种罕见但侵袭性较强的乳腺癌亚型,具有局部区域复发和远处转移的倾向,与乳腺癌死亡比例过高有关。IBC 在初始诊断时无法切除,多模式治疗被认为是 IBC 的标准治疗方法。这包括初始的系统治疗,随后是改良根治性乳房切除术以及全面的胸壁和区域淋巴结放疗。尽管采用了这种积极的多模式治疗策略,但与非炎性局部晚期乳腺癌相比,IBC 的预后仍然较差。对于初诊为 IV 期的 IBC 患者,治疗建议取决于肿瘤负荷、癌症亚型和合并症的存在。目前正在努力改善 IBC 的预后,但由于疾病的低发病率和该人群中专门研究的数量有限,进展受到了影响。乳腺癌中系统治疗的改进可能也会导致 IBC 的改善。需要更多专门的试验来确定可能有助于改善这些患者预后的其他治疗策略。此外,基于分子亚型和新辅助治疗反应等因素进行诊断和风险分层的更好框架对于 IBC 的进一步进展将非常重要。
