Second malignant lesions after therapy for Hodgkin's disease
Mayo Clinic Proceedings
|July 1, 1984
Summary
This study found that patients treated for Hodgkin's disease may have an increased risk of developing second malignant lesions, even after radiation therapy alone. Intensive treatments, including chemotherapy and radiation, appear to correlate with this heightened risk.
Area of Science:
- Oncology
- Clinical Medicine
- Cancer Research
Background:
- Hodgkin's disease is a cancer of the lymphatic system.
- Treatment for Hodgkin's disease has evolved, with various modalities including radiation therapy and chemotherapy.
Observation:
- A retrospective analysis of 169 adult patients with Hodgkin's disease treated between 1974-1978 was conducted.
- Four cases of second malignant lesions were identified among these patients, with a median follow-up of 4.1 years.
Findings:
- Second malignant lesions developed in four patients, all of whom had their Hodgkin's disease in remission.
- These patients had received intensive initial treatments, including total nodal irradiation or multiple chemotherapy cycles.
- A novel case of non-Hodgkin's lymphoma developing within a previously irradiated field after radiation therapy for Hodgkin's disease was observed.
Implications:
- Intensive therapeutic strategies for Hodgkin's disease may be associated with an increased risk of secondary malignancies.
- The findings suggest a definite risk for second malignant lesions following chemotherapy, combined-modality treatment, or even radiation therapy alone for Hodgkin's disease.
- Further long-term studies are warranted to fully elucidate the risks associated with different treatment protocols for Hodgkin's disease.
