Hodgkin's disease in children

Area of Science:

• Pediatric Oncology
• Radiation Oncology
• Medical Oncology

Background:

• Hodgkin's disease in children under 17 years was treated at Roswell Park Memorial Institute from 1921-1973.
• Treatment evolved through three distinct eras: early (1921-1949), middle (1950-1964), and recent (1965-1973).
• Therapeutic advancements included suboptimal radiation, improved radiation techniques with single-agent chemotherapy, and multiagent chemotherapy with advanced radiation therapy.

Purpose of the Study:

• To retrospectively analyze the treatment and outcomes of pediatric Hodgkin's disease.
• To evaluate the impact of evolving treatment strategies on patient survival.
• To identify prognostic factors influencing survival in pediatric Hodgkin's disease.

Main Methods:

• Retrospective analysis of 106 pediatric patients diagnosed with Hodgkin's disease between 1921 and 1973.
• Stratification of patients into three treatment eras based on therapeutic modalities.
• Evaluation of survival rates and prognostic factors associated with treatment outcomes.

Main Results:

• The recent era (1965-1973) demonstrated the highest five-year survival rate of 96% for early-stage disease.
• Favorable prognostic indicators included younger age (5-9 years), female sex, lymphocytic predominant histology, early stage, and complete treatment response.
• Nodular sclerosing and mixed cellularity subtypes showed similar prognoses.

Conclusions:

• Modern treatment approaches combining involved field radiotherapy and combination chemotherapy show promise for pediatric Hodgkin's disease.
• Further randomized studies are warranted to compare involved field radiotherapy with more extensive techniques in early-stage disease.
• Treatment advancements have significantly improved survival outcomes for children with Hodgkin's disease.
