Abstract:
With advances in cancer management, patients are living with the long-term sequelae of both cancer and its treatment. This era of cancer survivorship poses unique challenges to the interdisciplinary cancer team in terms of management and prevention of treatment-related toxicities. This paper describes the case of a 55-year-old patient with neurocognitive disturbance as a result of prophylactic cranial irradiation (PCI). Five years after a diagnosis of small cell lung cancer, she is now an inpatient at a specialist palliative care unit. The current evidence for PCI and for potentially modifiable risk factors for neurocognitive disturbance as a consequence of PCI is explored.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
