Abstract

Background: The modern-day therapeutic landscape for follicular lymphoma (FL) includes a number of highly effective therapies.

Patients and methods: We set out to determine progression-free survival (PFS) after front line, second line, and third line of therapy on the basis of relevant biological characteristics and therapeutic choices. Patients (n = 743, 51% females, median 60 years old) diagnosed with grade 1-2 FL between 1997 and 2016 in nine institutions were included.

Results: The median PFS1, PFS2, and PFS3 were 8.1 years (95% confidence interval [CI]: 7-9.3 years), 4.2 years (95% CI: 2.8-5.6 years) and 2.2 years (95% CI 1.7-2.8 years). We found longer PFS1 for (1) females, (2) younger age, (3) lower-risk follicular lymphoma international prognostic index (FLIPI), (4) standard intensity (over low intensity) regimens and (5) immunochemotherapy strategies and (6) maintenance rituximab. We found a shorter PFS2 for patients who received front-line immunochemotherapy. Older age at diagnosis correlated with a shorter PFS3. Intensity of front-line chemotherapy, maintenance, or POD24 status did not correlate with PFS2 or PFS3 in this dataset.

Interpretation: With current immunochemotherapy strategies, the natural course of FL is characterized by shorter-lasting remissions after each relapse. It will be interesting to see whether new therapies can alter this pattern.

临床实践中，滤泡性淋巴瘤患者在一线、二线和三线治疗后的无进展生存期。

背景：滤泡性淋巴瘤（FL）的现代疗法包括多种高效疗法：我们根据相关生物学特征和治疗选择，确定一线、二线和三线治疗后的无进展生存期（PFS）。研究纳入了1997年至2016年期间在9家机构确诊为1-2级FL的患者（n = 743，51%为女性，中位年龄60岁）：中位 PFS1、PFS2 和 PFS3 分别为 8.1 年（95% 置信区间 [CI]：7-9.3 年）、4.2 年（95% CI：2.8-5.6 年）和 2.2 年（95% CI：1.7-2.8 年）。我们发现，(1) 女性；(2) 年龄较小；(3) 低风险滤泡性淋巴瘤国际预后指数（FLIPI）；(4) 标准强度（高于低强度）方案；(5) 免疫化疗策略；(6) 利妥昔单抗维持治疗的 PFS1 较长。我们发现，接受一线免疫化疗的患者的 PFS2 较短。诊断时的高龄与较短的 PFS3 相关。在该数据集中，一线化疗强度、维持治疗或POD24状态与PFS2或PFS3无关：在目前的免疫化疗策略下，FL的自然病程特点是每次复发后的缓解持续时间较短。新疗法是否能改变这种模式将是一个有趣的问题。
