title: Treatment of lung cancer in elderly part II: small cell lung cancer.
abstract: There is a general trend worldwide of an increasing incidence of elderly population. Age is the greatest risk factor for cancer; therefore, this demographic shift is a main reason for an increase of cancer incidence. Lung cancer is a typical disease of the elderly patients. Small cell lung cancer (SCLC) accounts for approximately 20% of all lung cancer cases. This review summarises the issues of treatment of SCLC in elderly. The number of randomised phase III trials concerning treatment of SCLC in elderly patients are very limited. Although currently most treatment decisions are based on lower grades of evidence, some conclusions can be drawn from the current studies. Age alone is a very uncertain prognostic criteria for outcome or tolerability of treatment. Much more important is the geriatric assessment of each individual patient. Current treatment standards for limited disease (LD)-SCLC (polychemotherapy plus local thoracic irradiation and additional prophylactic cranial irradiation in case of complete remission) seems to be also feasible for 'fit' elderly (>70 years) LD-SCLC patients with a good performance and full functional capacities. There are preliminary data indicating that a similar outcome in elderly patients can probably be achieved a with reduced number of treatment schedules (e.g. 2 instead of 4 cycles in combination with radiotherapy. Surgical resection is also feasible in selected elderly patients with very early stage SCLC, where this maybe an appropriate approach, although no phase III data are available, which demonstrated the benefit of additional surgery compared to chemotherapy alone in early stage SCLC. In patients with extensive disease-SCLC age alone does not necessarily restrict the use of multiagent regimen, although the risk of haematological toxicity seems to be higher than in the younger patients. When standard treatment is not feasible due to co-morbidity or loss of functional capacity, several alternative combination regimens are available, which appear to be slightly superior to single agent treatment, although randomised data for elderly on that issue are sparse. Carboplatin and etoposide seems currently the most appropriate two-drug combination in elderly patients, but there are a variety of active and low toxic third generation agents like taxanes, gemcitabine and vinorelbine which are active in both, non-small cell lung cancer and SCLC. For the comparison of trials in elderly patients it will be of key importance to include a comprehensive and standardised geriatric assessment in such studies.
