Abstract

Introduction: Paraneoplastic neurological syndrome (PNS) is associated with small-cell lung cancer (SCLC). However, the frequency and characteristics of PNS and the efficacy of anticancer treatment for these patients have not been investigated in the Japanese/Asian population previously. Therefore, we aimed to better understand PNS by evaluating real-world data from patients with PNS complicated by SCLC.

Methods: Patients diagnosed with Stage II-IV SCLC at a single center between August 2007 and April 2021 were retrospectively analyzed. The primary outcome was the incidence of PNS. The secondary outcomes were the change in performance status (PS) after treatment commencement and outcomes following anticancer treatment, including objective response rate (ORR), progression-free survival (PFS), and overall survival (OS).

Results: A total of 318 patients were evaluated; PNS was present in 2.8% (n = 9) of the overall population. All patients with PNS exhibited poor Eastern Cooperative Oncology Group PS (≥2); moreover, 78% of patients had a PS score of 3-4. An improvement in PS was observed in 56% (n = 5) of patients. Patients with PNS exhibited treatment efficacies similar to patients without PNS (ORR: 89% vs. 83%, p = 1.0; PFS: 7.6 vs. 5.7 months, p = 0.69; OS: not reached vs. 15.6 months, p = 0.23).

Conclusions: A total of 2.8% of patients had SCLC complicated by PNS, with poor PS observed. However, anticancer therapy led to an improvement in PS and comparable ORR, as well as PFS and OS similar to those observed in patients without PNS. Thus, anticancer therapy should be considered in patients with PNS.

副肿瘤性神经综合征及其对小细胞肺癌治疗效果的影响：单中心回顾性分析

简介副肿瘤性神经综合征（PNS）与小细胞肺癌（SCLC）有关。然而，此前尚未在日本/亚洲人群中调查过副肿瘤性神经综合征的发生频率、特征以及抗癌治疗对这些患者的疗效。因此，我们旨在通过评估 SCLC 并发 PNS 患者的实际数据，更好地了解 PNS：方法：我们对 2007 年 8 月至 2021 年 4 月期间在一个中心确诊的 II-IV 期 SCLC 患者进行了回顾性分析。主要结果是PNS的发生率。次要结果是治疗开始后的表现状态（PS）变化和抗癌治疗后的结果，包括客观反应率（ORR）、无进展生存期（PFS）和总生存期（OS）：共对 318 例患者进行了评估，其中 2.8%（9 例）的患者存在 PNS。所有 PNS 患者的东方合作肿瘤学组 PS 均较差（≥2）；此外，78% 的患者 PS 评分为 3-4。56%的患者（n = 5）PS有所改善。PNS患者的疗效与无PNS患者相似（ORR：89% vs. 83%，p = 1.0；PFS：7.6 vs. 5.7个月，p = 0.69；OS：未达到 vs. 15.6个月，p = 0.23）：结论：共有2.8%的SCLC患者并发PNS，且PS较差。结论：共有2.8%的SCLC患者并发PNS，PS较差，但抗癌治疗可改善PS，提高ORR，延长PFS和OS，与未并发PNS的患者相似。因此，PNS 患者应考虑接受抗癌治疗。

期刊介绍： Thoracic Cancer aims to facilitate international collaboration and exchange of comprehensive and cutting-edge information on basic, translational, and applied clinical research in lung cancer, esophageal cancer, mediastinal cancer, breast cancer and other thoracic malignancies. Prevention, treatment and research relevant to Asia-Pacific is a focus area, but submissions from all regions are welcomed. The editors encourage contributions relevant to prevention, general thoracic surgery, medical oncology, radiology, radiation medicine, pathology, basic cancer research, as well as epidemiological and translational studies in thoracic cancer. Thoracic Cancer is the official publication of the Chinese Society of Lung Cancer, International Chinese Society of Thoracic Surgery and is endorsed by the Korean Association for the Study of Lung Cancer and the Hong Kong Cancer Therapy Society. The Journal publishes a range of article types including: Editorials, Invited Reviews, Mini Reviews, Original Articles, Clinical Guidelines, Technological Notes, Imaging in thoracic cancer, Meeting Reports, Case Reports, Letters to the Editor, Commentaries, and Brief Reports.
