Journal: Cancer imaging : the official publication of the International Cancer Imaging Society
This publication is an imaging-focused review of second malignant neoplasms (SMNs) in survivors of childhood cancer.
Key points:
- • Clinical importance: As pediatric cancer survival improves, SMNs have become a major late complication, responsible for nearly half of non-relapse deaths in long-term survivors.
- • Risk factors discussed:
- Prior chemotherapy exposure.
- Radiation therapy, including dose-related and field-related effects.
- Hereditary cancer predisposition syndromes.
- Hematopoietic stem cell transplantation and its associated conditioning regimens.
- • Common SMNs covered: Leukemia, thyroid carcinoma, sarcomas, and breast carcinoma are highlighted as frequent secondary cancers in this population.
- • Role of imaging: The review emphasizes:
- The importance of early detection through structured, risk-adapted imaging surveillance.
- Integration of imaging into long-term follow-up protocols to identify SMNs at a more curable stage.
- • Risk mitigation strategies:
- Dose modification and regimen refinement for chemotherapy.
- Use of advanced radiation techniques to limit normal tissue exposure.
- Implementation of comprehensive survivorship care, including long-term monitoring and counseling.
- • Forward-looking perspective: The authors stress the need for a dual focus in pediatric oncology—maximizing cure of the primary malignancy while minimizing late toxicities, particularly SMNs—through lifelong surveillance, tailored therapies, and interdisciplinary care models to improve both survival and quality of life.
