[Long-term organ toxicity of oncological therapies]

Cancer treatments, although life prolonging, are associated with side effects. The occurrence, duration, and severity of side effects vary, depending on treatment received. Long-term effects refer to effects that manifest during treatment and persist long after treatment has ended. Late effects are complications that occur after treatment has ended. These effects can have a negative impact on the functioning and quality of life of persons living with and beyond cancer. This overview aims to provide a non-exhaustive overview of the long-term and late effects associated with the traditional mainstay of cancer treatments (surgery, radiotherapy, chemotherapy) and newer treatments such as immunotherapy. In conclusion, long-term and late effects of cancer treatment can be associated with a high burden for those affected, including a reduction in their ability to function and health-related quality of life. Given the large and further growing number of cancer survivors and the abundance of long-term and late effects, it is essential to develop and implement risk-adapted, multidisciplinary survivorship care programmes.
