[A Real-World Single-Center Study of Adult Hodgkin's Lymphoma].

OBJECTIVE: To summarize the clinical characteristics, therapeutic effect and prognostic factors of patients with Hodgkin's lymphoma (HL).

METHODS: A total of 129 patients with HL diagnosed in Peking University Third Hospital from January 2010 to March 2021 who were given at least one efficacy assessment after treatment were enrolled, and their clinical data, including sex, age, pathological type, Ann Arbor stage, ECOG score, blood test, β2 -microglobulin, lactate dehydrogenase level, albumin level were collected. The clinical characteristics, therapeutic effect and long-term prognosis of the patients were summarized and analyzed.

RESULTS: In classical HL, nodular sclerosis HL accounted for the highest proportion of 51.6%, followed by mixed cellularity HL (36.5%), lymphocyte-rich classical HL (3.2%), and lymphocyte depletion HL (0.7%), while nodular lymphocyte predominant HL accounted for 4.8%. The 3-year overall survival (OS) rate of HL patients was 89.8%, and 5-year OS was 85.0%. The 3-year progression-free survival (PFS) rate was 73.4%, and 5-year PFS was 63.1%. Multivariate regression analysis indicated that IPI score was an independent negative factor, while hemoglobin (Hb) level was an independent positive factor for OS in HL patients. When the mediastinal mass size was 9.2 cm, it was most significant to judge the survival status of HL patients. 5-year OS and 5-year PFS were 97.4% and 76.0% in early-stage HL patients without large mass, respectively, while in patients with advanced-stage HL was 83.4% and 55.9% (both P < 0.05). After 2-4 courses of treatment, the overall response rate (ORR) of patients who received chemotherapy combined with radiotherapy was 95.0%, while that was 89.6% in those with chemotherapy alone.

CONCLUSIONS: The overall prognosis of patients with HL is satisfactory, especially those in early-stage without large mass. IPI score and Hb level are independent risk factors for the prognosis of HL patients. A 9.2 cm mediastinal mass can be used as the cut-off value for the prognosis of Chinese HL patients.
