Surprisingly, cancer in the elderly is frequently treated in a poor manner, and the behaviour of the disease in elderly patients is often poorly understood. Cancer treatment varies significantly with age, the percentage of patients receiving definitive treatment declines with increasing age, and there is a decline in survival of cancer with age. One of the contributing factors may be that physicians are less likely to recommend specialist consultation for elderly patients. One has to keep in mind that cancer surgery in the elderly, without any co-morbidity, is safe, and that, nowadays, the morbidity and mortality increases minimally with the age of the patient. In contrast, the morbidity and mortality is 2-3 fold as high in the elderly cancer patients with co-morbidity compared with younger cancer patients. A better public education of the elderly may increase cancer awareness, and therefore decrease the risk of developing symptoms that require emergency surgery, with a subsequent three times increase in the mortality rate. Surgeons treating elderly cancer patients should realise that performance status is more important than age, and should always keep in mind the three major questions as recently formulated by Balducci; (1) is the patient going to die of cancer or with cancer, (2) is the patient able to tolerate the surgery and possible surgical-related complications, and (3) is the patient likely to suffer the complications of cancer during her/his life? The increased number of surgical treatment options in elderly cancer patients will lead to an increase in overall cancer survival in elderly cancer patients, and contribute to an improvement in their quality of life. Surgical oncologists should focus on how to manage the most common cancers in elderly people such as breast, colorectal, lung and prostate, as well as take an active part in palliative treatments.
