Esophageal gastrointestinal stromal tumors (E-GIST) and leiomyosarcoma (E-LMS) are rare tumors. Previous studies are limited to small number of patients. We sought to study these two tumors using a large national database.
The National Cancer Data Base 2004-2014 was queried for patients with E-GIST and E-LMS. The primary outcome was overall survival (OS). Univariate and multivariable Cox regression models were used to investigate OS predictors.
We found 141 E-GIST and 38 E-LMS patients, with esophagectomy and systemic treatment rate of 55% and 49% for E-GIST and 50% and 26% for E-LMS. The 5-year OS of E-GIST and E-LMS were 62% and 23%, respectively, p < 0.001. In multivariable analysis, young age, tumor <10 cm, esophagectomy, and E-GIST were associated with superior OS. There was a higher median and mean OS with neoadjuvant vs. upfront surgery for E-GIST group (98 and 111 vs 79 and 80 months).
E E-GIST has superior OS compared to E-LMS. Esophagectomy is the cornerstone treatment modality. Further studies are needed to evaluate the role of neoadjuvant therapy in E-GIST patients.
食管胃肠道间质瘤(E-GIST)和平滑肌肉瘤(E-LMS)是罕见的肿瘤。既往研究的病例数有限。我们旨在使用大型国家数据库研究这两种肿瘤。
从 2004 年至 2014 年的国家癌症数据库中查询 E-GIST 和 E-LMS 患者。主要结果是总生存(OS)。使用单因素和多因素 Cox 回归模型来探讨 OS 的预测因素。
我们发现了 141 例 E-GIST 和 38 例 E-LMS 患者,E-GIST 和 E-LMS 的手术切除率和系统治疗率分别为 55%和 49%、50%和 26%。E-GIST 和 E-LMS 的 5 年 OS 分别为 62%和 23%,p<0.001。多因素分析显示,年轻、肿瘤<10cm、手术切除和 E-GIST 与更好的 OS 相关。对于 E-GIST 组,新辅助治疗与直接手术相比,中位和平均 OS 更高(98 和 111 个月 vs. 79 和 80 个月)。
E-GIST 的 OS 优于 E-LMS。手术切除是基石治疗方法。需要进一步研究来评估新辅助治疗在 E-GIST 患者中的作用。
