ABSTRACT

Advanced stage nodular lymphocyte predominant Hodgkin lymphoma (nLPHL) is extremely rare in children and as a consequence, optimal treatment for this group of patients has not been established. Here we retrospectively evaluated the treatments and treatment outcomes of 41 of our patients from the UK and France with advanced stage nLPHL. Most patients received chemotherapy, some with the addition of the anti CD20 antibody rituximab or radiotherapy. Chemotherapy regimens were diverse and followed either classical Hodgkin lymphoma or B non-Hodgkin lymphoma protocols. All 41 patients achieved a complete remission with first line treatment and 40 patients are alive and well in remission. Eight patients subsequently relapsed and 1 patient died of secondary cancer (9 progression-free survival events). The median time to progression for those who progressed was 21 months (5·9-73·8). The median time since last diagnosis is 87·3 months (8·44-179·20). Thirty-six (90%), 30 (75%) and 27 (68%) patients have been in remission for more than 12, 24 and 36 months, respectively. Overall, the use of rituximab combined with multi-agent chemotherapy as first line treatment seems to be a reasonable therapeutic option.

ABSTRACT

Nodular lymphocyte predominant Hodgkin disease (NLPHL) differs clearly from classical Hodgkin lymphoma (cHL) by clinical presentation and more favorable outcome. Patients often present with early stage IA or IIA. Extranodal disease and B-symptoms are uncommon. Histologically, NLPHL is characterized by the presence of atypical "lymphocyte predominant cells" (LP cells) or "pop-corn" cells in a non-neoplastic and reactionnal nodular background of small mature B-lymphocytes. LP cells are negative for CD30 and positive for CD20, BCL6 and EMA (in half of the cases). FDG-PET plays an important role in evaluation of cHL and NLPHL for staging, therapy assessment and relapse. Historically, patients with NLPHL have been treated like patients with cHL, but their very favorable prognosis and the risk of late complications of chemotherapy and/or radiotherapy have led to a de-escalation in recent years. Patients with early stage could be treated by surgical adenectomy alone or associated with not intensive chemotherapy. Currently, there is no consensus regarding to the optimal treatment of patients with advanced stage. Rituximab used as monotherapy or in association with chemotherapy has achieved complete or partial responses. The outcome of NLPHL is singular by the frequent occurrence of late relapses and the risk of transformation into aggressive B lymphoma justifying an extended follow-up. Further prospective studies are needed to optimize treatment of these advanced and recurrent forms.

ABSTRACT

There is little data available regarding children and adolescents with Hodgkin lymphoma (HL) who relapse after combined-modality treatment, even though they have a substantial chance of cure. The purpose of this national retrospective study was to evaluate the outcome of patients with recurrent/refractory HL and determine adverse prognostic factors. From 1990 to 2006, 70 patients (median age 13·9 years) with refractory (n = 31) or first relapse (n = 39) HL were identified. Median time from end of treatment to relapse was 6 months (3-56). Relapses occurred in irradiated areas in 43/70 patients. Salvage therapy consisted of chemotherapy and 50 patients received high-dose chemotherapy with autologous stem cell transplantation. Radiotherapy was performed in 29 cases, tandem autologous transplantation in five and allograft in three. With a median follow-up of 40 months (2-140), significant prognostic factors were time to progression/relapse and response to therapy before autograft. Event-free survival and overall survival in patients with refractory disease, early relapse and late relapse were 35 ± 9%, 67 ± 11%, 76 ± 10% and 48 ± 11%, 89 ± 7% and 80 ± 10%, respectively. As progression <3 months was a major adverse prognostic factor, novel therapeutic approaches are needed for this group of patients. By contrast, patients have substantial chance of long term second remission in case of relapse >3 months.

ABSTRACT

PURPOSE: To examine whether three cycles of a low-intensity chemotherapy consisting of cyclophosphamide [500 mg/m(2) - day 1], vinblastine [6 mg/m(2) - days 1 and 8] and prednisolone [40 mg/m(2) - days 1-7] (CVP) is safe and therapeutically effective in children and adolescents with early stage nodular lymphocyte predominant Hodgkin lymphoma [nLPHL]. PATIENTS AND METHODS: Fifty-five children and adolescents with early stage nLPHL [median age 13 years, range 4-17 years] diagnosed between June 2005 and October 2010 in the UK and France are the subjects of this report. Staging investigations included conventional cross sectional as well as 18 fluro-deoxyglucose [FDG] PET imaging. Histology was confirmed as nLPHL by an expert pathology panel. RESULTS: Of the 45 patients, who received CVP as first line treatment, 36 [80%, 95% Confidence Interval [CI]: (68; 92)] either achieved a complete remission [CR] or CR unconfirmed [CRu], the remaining nine patients achieved a partial response. All nine subsequently achieved CR with salvage chemotherapy [n=7] or radiotherapy [n=2]. Ten patients received CVP at relapse after primary treatment that consisted of surgery alone and all achieved CR. To date, only three patients have relapsed after CVP chemotherapy and all had received CVP as first line treatment at initial diagnosis. The 40-month freedom from treatment failure and overall survival for the entire cohort were 75.4% (SE ± 6%) and 100%, respectively. No significant early toxicity was observed. CONCLUSIONS: Our results show that CVP is an effective chemotherapy regimen in children and adolescents with early stage nLPHL that is well tolerated with minimal acute toxicity.

ABSTRACT

BACKGROUND: Lymphocyte-predominant Hodgkin lymphoma (LPHL) is a rare, CD20-positive, good prognostic lymphoma in children. Patients with early-stage LPHL who underwent successful surgical lymph node resection alone have been reported. To clarify the optimum treatment strategy in children, European study groups were asked to report their experience of surgery alone used in the treatment of pediatric LPHL. METHODS: Data from 58 patients were collected by the French Society for Pediatric Cancers, the German-Austrian Pediatric Study Group/German Society of Pediatric Oncology and Hematology (Germany), and the Children's Cancer and Leukaemia Group (United Kingdom). In total, there were 50 boys and 8 girls, and the median age was 11 years (age range, 4-17 years). Fifty-four patients had stage IA disease, 2 patients had stage IIA disease, and 2 patients had stage IIIA disease. RESULTS: With a median follow-up of 43 months (range, 2-202 months), the overall survival rate was 100%, and the progression-free survival (PFS) rate was 57%. Fifty-one of 58 patients achieved complete remission (CR) after surgery. In the CR group, the overall PFS rate was 67% (95% confidence interval, 51-82%). All seven patients who had residual disease after initial surgery developed recurrences (P = .003). Among 18 patients with stage IA LPHL who developed recurrent disease, 11 patients had local recurrences, and 7 patients recurred in stage IIA. One patient with stage IIIA disease presented with high-grade B-cell non-Hodgkin lymphoma at 10 years of follow-up. CONCLUSIONS: When complete resection was achieved, a substantial proportion of patients with surgically treated, early-stage LPHL experienced long-term remission and actually may have been cured.
