Features of the Course of Radioinduced Breast Cancer. Clinical Observation

Abstract

Introduction . Hodgkin’s lymphoma is most commonly reported in the young age of 20 to 40 years. Radiation therapy remained the first-choice option before the advent of modern chemotherapy agents. Thereafter, the risk of radioinduced breast cancer after radiotherapy with total radiation dose of 38 Gy or more increased 4.5-fold. Materials and methods . The presented clinical case demonstrates aggressive breast cancer that developed 43 years after radiation therapy for Hodgkin's lymphoma. Results and discussion . In the 1990s, chemotherapy regimens for Hodgkin’s lymphoma were not effective enough to control the disease, therefore, radiotherapy was an indispensable measure. Secondary radioinduced tumors take the second place (26 %) in the structure of mortality from Hodgkin’s lymphoma. The emergence of new, more effective chemotherapy regimens reduced the risk of secondary tumors and, in particular, breast cancer. Conclusion . At present, up to 75 % of patients with Hodgkin’s lymphoma can be cured using modern methods of chemotherapy and radiation therapy. In follow-up care, it is necessary to consider the high risk of secondary malignant neoplasms, especially lung and breast cancer.
