title: Chemotherapy in elderly patients with advanced lung cancer. Part I: General aspects and treatment of small cell lung cancer (SCLC).
abstract: There is much uncertainty whether chemotherapy is beneficial for elderly patients with advanced lung cancer. Whereas age alone is not an adverse prognostic factor, decline of physiological function and comorbidity can result in higher rates of treatment-related toxicity, in particular myelosuppression. The higher incidence of comorbid conditions, frequently sharing the risk profile of the malignancy, can translate into worse survival. Therefore, a geriatric assessment of the patient's overall situation should guide decision-making. Mainstay of treatment of small cell lung cancer (SCLC), also in the elderly, is combination therapy. Several retrospective analyses reveal that in elderly patients often lower drug doses are delivered. However, the treatment outcome of these patients does not appear to be worse compared to younger patients. For functionally independent elderly patients, combination chemotherapy with carboplatin and etoposide, supported by optimized supportive care, possibly including hematopoietic growth factors (G-CSF) to minimize toxicity, should be considered. Special attention to renal function should be given and individualized drug dosing, adapted to the glomerular filtration rate, is mandatory. For patients with some functional dependence or showing a certain degree of comorbidity, preliminary data indicate that single-agent therapy with carboplatin can confer the same benefit as combination chemotherapy, but with reduced toxicity. Single agent oral etoposide, however, seems to be inferior to combination treatment and should not be given routinely in the treatment of this cohort. Further evaluation of these topics is needed, and can be achieved by trials specifically designed for elderly patients or patients with reduced performance status.
