BACKGROUND
The objectives of this study were to summarize a single-institution experience in treating patients with inflammatory breast carcinoma (IBC) using trimodality therapy and to identify prognostic factors for outcome.
METHODS
Sixty-one women underwent radiation therapy with curative intent for IBC between 1982 and 2001. All but five women received trimodality therapy. Neoadjuvant chemotherapy was given to the majority of women (n = 43 patients), although some received "up-front" surgery as first therapy (n = 18 patients).
RESULTS
With a median potential observation time after diagnosis of 14 years, freedom from locoregional disease progression was 78%, freedom from distant metastasis was 45%, and the cause-specific survival rate was 47% at 5 years. Approximately 40% of the 56 patients who received trimodality therapy remained free of disease. Multivariate analysis demonstrated three factors that were found to be associated significantly with improved cause-specific survival: pathologic tumor size < 4 cm (P = 0.0001), up-front surgery (P = 0.0078), and local disease control (P = 0.0003). Factors that were found to be associated with better freedom from locoregional disease progression were pathologic tumor size (< 4 cm; P = 0.0157), age (> 55 years; P = 0.0596), and radiation dose (> or = 60 grays [Gy]; P = 0.0621).
CONCLUSIONS
IBC is an aggressive disease that is treated effectively in select patients by multimodality therapy. Patient outcomes may be improved with therapies that result in better local and systemic control. Further studies are warranted to address the optimal sequence of trimodality therapy and the optimal administration of each agent.
背景
本研究的目的是总结单机构采用三联疗法治疗炎性乳腺癌(IBC)患者的经验,并确定预后的相关因素。
方法
1982年至2001年间,61名女性因IBC接受了根治性放疗。除5名女性外,其余均接受了三联疗法。大多数女性(n = 43例患者)接受了新辅助化疗,不过有些患者接受了“先行”手术作为首次治疗(n = 18例患者)。
结果
诊断后的中位潜在观察时间为14年,5年时局部区域无病进展率为78%,远处无转移率为45%,病因特异性生存率为47%。接受三联疗法的56例患者中约40%仍无疾病。多因素分析显示,有三个因素与病因特异性生存率提高显著相关:病理肿瘤大小<4 cm(P = 0.0001)、先行手术(P = 0.0078)和局部疾病控制(P = 0.0003)。与局部区域无病进展更好相关的因素有病理肿瘤大小(<4 cm;P = 0.0157)、年龄(>55岁;P = 0.0596)和放疗剂量(≥60格雷[Gy];P = 0.0621)。
结论
IBC是一种侵袭性疾病,在部分患者中通过多模式疗法可得到有效治疗。采用能更好地实现局部和全身控制的疗法可能会改善患者的预后。有必要进一步开展研究,以确定三联疗法的最佳顺序以及每种药物的最佳给药方式。
