Hodgkin Lymphoma in Children: A 16-year Experience at the Children's Welfare Teaching Hospital of Baghdad, Iraq.

Background

Childhood Hodgkin lymphoma (HL) is an eminently curable disease. Good outcomes can be achieved even in resource-limited settings, and the focus is increasingly on limiting long-term toxicity. Contemporary treatment incorporates a risk-stratified, response-adapted approach using multiagent chemotherapy with/without low-dose radiotherapy. Many developing countries continue to use ABVD-based regimens due to limited acute toxicity, cost, and ease of delivery.

Objective

We herein report the outcomes of childhood HL diagnosed and treated in an Iraqi single centre over 16 years.

Methods

Children ≤14 years old with biopsy-proven HL were enrolled. Most patients received ABVD chemotherapy or COPP/ABV when Dacarbazine was unavailable. Radiotherapy was not available.

Results

Three hundred-three children were consecutively newly diagnosed with HL; 284 were considered eligible for the retrospective analysis (treatment refusals 9; deaths before therapy 5; initially diagnosed of non-Hodgkin lymphoma 5). ABVD scheme was administered to 184 children (65%), COPP/ABV to 83 (29%), and other schemes to the remaining 17 patients. Complete response (CR) was achieved in 277 (98%); 4 (1.4%) showed disease progression, and 1 had stable disease. Four patients in CR abandoned therapy and were in CR at the time of analysis, 2 died from infection. Relapse occurred in 42 patients (15%). The 15-year OS and EFS are 89.7% and 70.3%, respectively.

Conclusion

In this single Centre, over 16 years, almost 90% of children suffering from HL survive, despite the numerous limitations in diagnostic procedures, shortage of chemotherapy, no radiotherapy facilities, absence of effective second-line treatments, and finally, therapy abandonment for social and financial reasons.
