Follicular lymphoma (FL) is the most common indolent non-Hodgkin lymphoma, which typically affects mature adults and elderly, whose median age at diagnosis is 65 years. The natural history of FL appears to have been favorably impacted by the introduction of Rituximab. Randomized clinical trials demonstrated that the addition of rituximab to standard chemotherapy induction has improved the overall survival and new strategies of chemo-immunotherapy, such as Bendamustine combined with Rituximab, showed optimal results on response and reduced hematological toxicity, becoming one of the standard treatments, particularly in elderly patients. Moreover, maintenance therapy with Rituximab demonstrated improvement of progression-free survival. Despite these exciting results, FL is still an incurable disease. It remains a critical unmet clinical need finding new prognostic factors to identify poor outcome patients better, to reduce the risk of transformation and to explore new treatment strategies, especially for patients not candidate to intensive chemotherapy regimens, such as elderly patients. Some progress were already reached with novel agents, but larger and more validated studies are needed. Elderly patients are the largest portion of patients with FL and represent a subgroup with higher treatment difficulties, because of comorbidities and smaller spectrum for treatment choice. Further studies, focused on elderly follicular lymphoma patients, with their peculiar characteristics, are needed to define the best-tailored treatment at diagnosis and at the time of relapse in this setting.
滤泡性淋巴瘤(FL)是最常见的惰性非霍奇金淋巴瘤,通常影响成年人和老年人,其诊断时的中位年龄为65岁。利妥昔单抗的引入似乎对FL的自然病程产生了有利影响。随机临床试验表明,在标准化疗诱导方案中加入利妥昔单抗可提高总生存率,而诸如苯达莫司汀联合利妥昔单抗等化疗免疫治疗新策略在疗效和降低血液学毒性方面显示出最佳效果,成为标准治疗方案之一,尤其适用于老年患者。此外,利妥昔单抗维持治疗可改善无进展生存期。尽管取得了这些令人振奋的结果,但FL仍然是一种无法治愈的疾病。寻找新的预后因素以更好地识别预后不良的患者、降低转化风险并探索新的治疗策略,尤其是针对不适合强化化疗方案的患者(如老年患者),仍然是一项关键的未满足临床需求。新型药物已经取得了一些进展,但仍需要更大规模且经过更多验证的研究。老年患者是FL患者中的最大群体,由于合并症和治疗选择范围较窄,他们是治疗难度较高的亚组。需要针对具有特殊特征的老年滤泡性淋巴瘤患者进行进一步研究,以确定在这种情况下诊断和复发时最适合的治疗方案。
