Cancer in older patients: an analysis of elderly oncology

Is it possible to define when someone is elderly? The worldwide population is growing not only in number but also in age; it is estimated that the population will increase to around 750 million by 2021. Two thirds of cancer occurs in the over 65 age groups. With an increasing elderly population, it can be derived that cancer will become a more prevalent condition. The burden of cancer on the medical profession will be even more apparent than before. In addition the elderly age group has different needs compared with younger oncology patients; there can be no ‘rule of thumb’ with the management of elderly illness. Factors such as frailty are significant when treating cancer in the older patients. The assessment of quality of life in older patients with cancer is also an important factor. Is it best for a patient to enjoy life as it is with cancer or aim for increased life expectancy by undertaking treatment with the threat of morbidity however severe during that period? The volume of scientific evidence currently available to support all the issues in geriatric oncology is greatly limited; almost all treatments designed for oncology are being tested in randomized clinical trials preferentially using younger cohorts of patients. Changes need to be made in order to further this field of medicine. Geriatric oncology is no longer a palliative field, as a healthy active life can now be expected by some older patients. The burden of oncology in the elderly will need to take a modern approach regarding the management of these patients.
