Фолликулярная лимфома (Фл) относится к индолентным зрелоклеточным В-клеточным лимфомам и, несмотря на рецидивирующее течение, в целом характеризуется благоприятным прогнозом с многолетней общей выживаемостью. Однако примерно в 20 % случаев заболевание имеет агрессивное течение с ранним прогрессированием и 5-летней общей выживаемостью всего 50 %, что свидетельствует о биологической неоднородности Фл. Ввиду крайне неблагоприятного прогноза случаи с прогрессированием заболевания в течение 2 лет от начала лечения представляют большую клиническую проблему. Какие прогностические модели риска ранней прогрессии Фл нам доступны и какие режимы 2-й и последующих линий противоопухолевой терапии использовать? Нужна ли высокодозная консолидация и когда? Выбор оптимальной терапии при ранней прогрессии Фл является сложной задачей и зависит как от варианта проведенного ранее лечения и статуса пациента, так и от объективно доступных терапевтических возможностей. В случае ранней прогрессии Фл после проведенной иммунохимиотерапии применяют альтернативный режим на основе ранее не использованного моноклонального антитела к СD20 (ритуксимаба или обинутузумаба) и химиопрепаратов неперекрестного действия. При СНОР-подобной индукционной терапии оптимальным препаратом 2-й линии является бендамустин. Кроме цитостатиков в комбинации с моноклональными антителами к СD20 в настоящее время в терапии Фл активно применяют новые агенты (иммуномодуляторы, ингибиторы сигнальных путей В-клеточного рецептора и гистонметилтрансферазы, BCL-2-ингибиторы и др.). В многочисленных клинических исследованиях продолжается активный поиск перспективных терапевтических опций для лечения Фл с тестированием новых лекарственных препаратов к другим В-клеточным мишеням и различными механизмами действия. В статье представлен клинический случай Фл с ранней генерализованной прогрессией, неэффективностью последующей интенсификации лечения с аутологичной трансплантацией гемопоэтических стволовых клеток и выбором терапии спасения в реалиях 2009-2012 гг.
Classical Hodgkin's lymphoma is one of the most treatable lymphoproliferative diseases with current chemotherapy regimens. The 5-year overall survival rate among patients after initial chemotherapy reaches 95 %, however, despite the significant success achieved, the problem of refractoriness/relapse remains very relevant. A standard approach to the treatment of refractory/recurrent Hodgkin's lymphoma among young patients with preserved general status and chemoresponsive to salvage therapy tumor is high-dose consolidation chemotherapy followed by transplantation of autologous hematopoietic stem cells. The intensification of chemotherapy regimens is highly difficult task for a doctor during the COVID-19 pandemic, which requires careful assessment of a risk-benefit ratio.In current conditions, new targeted and immune drugs are used to overcome resistance and reduce toxicity among pretreated patients, which allows not only to improve the results of a treatment, but also to preserve the high quality of life among patients with extremely unfavorable prognosis.We show our experience of using a checkpoint inhibitor in combination with a dose-intensive regimen of DHAP (dexamethasone, cytarabine, cisplatin) in the treatment of a refractory classical Hodgkin's lymphoma followed by high-dose consolidation chemotherapy and allogeneic hematopoietic stem cells transplantation, among patients complicated with a new coronavirus infection in the post-transplant period.
Despite significant progress made in recent decades in the treatment of classical Hodgkin's lymphoma, in 1030% of patients develop a refractory course or relapse of the disease. The effectiveness of therapy of the second and subsequent lines is about 50%. A significant breakthrough in the treatment of recurrent/refractory forms of classical Hodgkin's lymphoma has been the introduction of targeted drugs. The inclusion of new drugs in previously standard rescue therapy regimens significantly improves the effectiveness of the therapy. A clinical case of treating a patient with the progression of classical Hodgkin's lymphoma after first-line therapy, the use of brentuximab vedotin in combination with bendamustine as a rescue therapy with the achievement of complete remission, followed by high-dose consolidation with autologous hematopoietic stem cell transplantation is presented.
Aim. To study the efficacy and safety of combined immunochemotherapy according to the DHAp protocol + nivolumab in patients with refractory/relapsed classical Hodgkin's lymphoma before autologous hematopoietic stem cell transplantation.Materials and methods. The study consisted of 2 phases: 1st - immunotherapy with nivolumab (2 injections as monotherapy at a dose of 240 mg/day with 14 days interval); 2nd - combined immunochemotherapy according to the DHAp protocol + nivolumab (14 days after the 2nd administration of nivolumab): nivolumab 480 mg/day on day 1 in combination with chemotherapy according to the DHAp protocol, 4 cycles in total. The effectiveness of therapy was evaluated after 2 injections of nivolumab, after 2 and 4 cycles of combination therapy. from March 2020 to November 2021, 32 patients were included in the study. The median age was 34 (18-55) years.Results. As of November 2021, the result was evaluated in 32 patients after the 1st stage of treatment (nivolumab monotherapy). A complete response was obtained in 4 (12.5 %) patients, a partial response in 20 (62.5 %) patients, disease stabilization was noted in 5 (16 %) patients, an indeterminate response in 3 (9 %) patients. At the 2nd phase, the efficacy after the 2nd cycle of DHAp + nivolumab was evaluated in 31 patients (complete response was obtained in 19 (61 %), partial response in 11 (36 %)); the final efficacy evaluation (after the 4th cycle of DHAp + nivolumab) was performed in 30 patients, and all patients achieved response to therapy (complete response in 25 (83 %), partial response in 5 (17 %)). 2 patients were excluded from the study.Conclusion. preliminary results of combined immuno- and chemotherapy according to the DHAp protocol showed high efficacy and relatively low toxicity in patients with refractory/relapsed classical Hodgkin's lymphoma before autologous hematopoietic stem cell transplantation.
