Sinonasal undifferentiated carcinoma (SNUC) is a very rare entity with a poor prognosis. Due to the lack of studies on the subject, evidence is lacking concerning its management.
A multicenter collaborative study was conducted to assess treatment strategy, oncological outcome, and prognostic factors.
Definitive analyses focused on 54 patients with a majority of advanced stage; the 3-year overall survival (OS) and 3-year recurrence-free survival (RFS) rates were, respectively, 62.4% and 47.8%. During the follow-up, 18 patients (33.3%) died, 10 (18.5%) developed metastases, 7 had lymph-node involvement (13%), and 12 (22.2%) showed recurrence or local progression. In univariate analyses, treatment modalities associated with improved RFS were induction chemotherapy (p = 0.02) and intensity-modulated radiotherapy (p = 0.007). In the multivariate analyses, only induction chemotherapy (p = 0.047, hazard ratio [HR] = 0.39) was significantly associated with improved RFS.
Multimodal therapies including induction chemotherapy and intensity-modulated radiotherapy may improve the prognosis of SNUC; surgery might improve local control. Further multicenter studies are required.
嗅神经母细胞瘤(SNUC)是一种非常罕见的实体瘤,预后较差。由于缺乏对此类疾病的研究,其治疗管理缺乏证据。
进行了一项多中心协作研究,以评估治疗策略、肿瘤学结果和预后因素。
明确分析集中在 54 例晚期患者;3 年总生存率(OS)和 3 年无复发生存率(RFS)分别为 62.4%和 47.8%。在随访期间,18 例患者(33.3%)死亡,10 例(18.5%)发生转移,7 例有淋巴结受累(13%),12 例(22.2%)出现复发或局部进展。单因素分析显示,诱导化疗(p=0.02)和调强放疗(p=0.007)与 RFS 改善相关。多因素分析显示,只有诱导化疗(p=0.047,风险比[HR]为 0.39)与 RFS 的改善显著相关。
包括诱导化疗和调强放疗在内的多模态治疗方法可能改善 SNUC 的预后;手术可能提高局部控制率。需要进一步的多中心研究。
