PURPOSE: Hodgkin lymphoma is the most common cancer in children, adolescents, and young adults. Overall survival is approximately 80% to 90%. A subset of these patients has refractory disease or experience disease relapse. Conventional salvage therapies and autologous stem-cell transplantation is usually considered the standard of care for these patients. Our analysis reports outcomes in these patients. PATIENTS AND METHODS: After institutional review board approval, a retrospective analysis of patients with Hodgkin lymphoma who were up to 18 years of age and who had refractory or relapsed disease at Shaukat Khanum Memorial Cancer Hospital and Research Centre from September 2009 to December 2013 was performed. Patients who underwent high-dose chemotherapy followed by stem-cell rescue were included in this analysis. RESULTS: A total of 567 patients with Hodgkin lymphoma registered at the hospital. Sixty of the patients (10.6%) had either primary progressive or refractory disease or relapse after finishing with first-line chemotherapy. High-dose chemotherapy followed by stem cell was administered to 25 of these patients (42%). Thirteen patients (40%) had progressive disease (PD), five (22%) had early relapse, and seven (38%) had late relapse. A number of salvage regimens were used, including etoposide, prednisolone, ifosfamide, and cisplatin; dexamethasone, cytarabine, and carboplatin; and gemcitabine plus vinorelbine. Re-evaluation was performed before taking patients to a high dose, and it showed complete response in 17 patients (68%), partial response in six patients (24%), and PD in two patients (8%). Twenty-one patients (84%) are in remission after transplantation, with two patients (8%) having died as a result of disease progression and two patients (2%) having relapsed after treatment. Overall survival is 92% at 4 years, with event-free survival of 80% at 4 years. CONCLUSION: Our retrospective analysis shows good outcomes in patients who had PD or refractory disease. Disease response before transplantation is important in predicting outcomes.
