Hodgkin lymphoma in children: clinical analyses of 20 cases / 白血病·淋巴瘤

ABSTRACT

Objective To summarize the long-term outcomes and safety of childhood Hodgkin lymphoma (HL) with protocol ABVD. Methods The clinical data of 20 children with HL admitted to the Union Hospital of Fujian Medical University from July 2010 to June 2017 were retrospectively analyzed. Among the 20 children with HL, 15 were male and 5 were female. The median age of initial diagnosis was 6.5 years old (3-12 years old). The pathological types were as follow: 1 case was nodular lymphocyte-predominant HL (NLPHL) and 19 cases were classical HL (cHL), including 9 cases of mixed cell type, 9 cases of nodular sclerosis type and 1 case of lymphocyte rich type. Basing on Ann Arbor staging system, 1 patient was evaluated as stage Ⅰ, 4 patients were stage Ⅱ, 10 patients were stage Ⅲ, and 5 patients were stage Ⅳ. There were 3 patients in the low-risk group, 7 patients in the intermediate-risk group, and 10 patients in the high-risk group. There were 9 patients with B symptoms. All patients were treated with the ABVD regimen. Results All the 20 patients completed all chemotherapy courses. After 2 courses, the effective rate was 100％(20/20), including 12 cases of complete remission (CR) and 8 cases of partial remission (PR). After the treatment, 19 cases achieved CR, and at the end of the 6 courses, the evaluation showed that 1 case had residual lesions. Follow-up to February 2018, clinical symptoms of 18 cases achieved CR, 2 cases relapsed (all high-risk group); the median follow-up time was 42 months (10.1-87.9 months), the overall survival rate was 100 ％ (20/20), the estimated 5-year rate of freedom from treatment failure (FFTF) was (89.1 ±7.3) ％.Conclusions According to the risk stratification, ABVD regimen has good safety and long-term efficacy for children with cHL. Even the patients in low-risk or intermediate-risk group do not achieve CR after 2 courses and do not receive radiotherapy, the prognosis of them is still good.
