INTRODUCTION This study aims to report the efficacy and safety of capecitabine plus temozolomide (CAPTEM) across different lines of treatment in patients with metastatic neuroendocrine tumors (NETs). METHODS We conducted a multicenter retrospective study analyzing the data of 308 patients with metastatic NETs treated with CAPTEM between 2010 and 2022 in 34 different hospitals across various regions of Turkey. RESULTS The median follow-up time was 41.0 months (range: 1.7-212.1), and the median age was 53 years (range: 22-79). Our results across the entire patient cohort showed a median progression-free survival (PFS) of 10.6 months and a median overall survival (OS) of 60.4 months. First-line CAPTEM treatment appeared more effective, with a median PFS of 16.1 months and a median OS of 105.8 months (median PFS 16.1, 7.9, and 9.6 months in first-, second- and ≥third-line respectively, P = .01; with median OS values of 105.8, 47.2, and 24.1 months, respectively, P = .003) In terms of ORR, the first-line treatment again performed better, resulting in an ORR of 54.7% compared to 33.3% and 30.0% in the second and third or higher lines, respectively (P < .001). Grade 3-4 side effects occurred only in 22.5% of the patients, leading to a discontinuation rate of 9.5%. Despite the differences in outcomes based on treatment line, we did not observe a significant difference in terms of side effects between the first and subsequent lines of treatment. CONCLUSIONS AND RELEVANCE The substantial superior outcomes in patients receiving first-line CAPTEM treatment highlight its potential as an effective treatment strategy for patients with metastatic NET.

卡培他滨和替莫唑胺方案对神经内分泌肿瘤的疗效:来自土耳其肿瘤学组的数据。

简介 本研究旨在报告卡培他滨联合替莫唑胺 (CAPTEM) 在不同治疗方案中对转移性神经内分泌肿瘤 (NET) 患者的疗效和安全性。方法 我们进行了一项多中心回顾性研究,分析了 2010 年至 2022 年土耳其不同地区 34 家不同医院的 308 名转移性 NET 患者接受 CAPTEM 治疗的数据。结果中位随访时间为41.0个月(范围:1.7-212.1),中位年龄为53岁(范围:22-79)。我们对整个患者队列的结果显示,中位无进展生存期 (PFS) 为 10.6 个月,中位总生存期 (OS) 为 60.4 个月。一线 CAPTEM 治疗似乎更有效,中位 PFS 为 16.1 个月,中位 OS 为 105.8 个月(一线、二线和≥三线的中位 PFS 分别为 16.1、7.9 和 9.6 个月,P = .01 ;中位 OS 值分别为 105.8、47.2 和 24.1 个月,P = .003)就 ORR 而言,一线治疗再次表现更好,ORR 为 54.7%,而一线治疗的 ORR 为 33.3% 和 30.0%分别为第二行和第三行或更高行 (P < .001)。仅 22.5% 的患者出现 3-4 级副作用,导致停药率为 9.5%。尽管不同治疗线的结果存在差异,但我们没有观察到第一线治疗和后续治疗线之间副作用方面存在显着差异。结论和相关性 接受一线 CAPTEM 治疗的患者的显着优异结果凸显了其作为转移性 NET 患者有效治疗策略的潜力。
