Abstract
Non-small cell lung cancer (NSCLC) may be considered typical of advanced age. Most cases of NSCLC are diagnosed in the advanced or locally advanced stage. It has been shown that combined chemo-radiotherapy is more efficient than either chemotherapy alone or radiation alone, for the therapeutic management of localized unresectable NSCLC. However, chemo-radiotherapy, even if given with sequential approach, in clinical practice can be contraindicated in elderly patients. In fact, this patient population often present at diagnosis with cardiovascular and/or pulmonary comorbidities that increase the risk of severe side effects from chemo-radiotherapy. The present review aims at focusing the currently available evidences on the treatment of elderly patients affected by locally advanced NSCLC and at giving future perspectives on this topic. Very few specific prospective data are available on the treatment of locally advanced NSCLC in the elderly. Some phase II studies suggest that low-dose chemotherapy given concurrently with radiotherapy could be safely administered to this patient population. Retrospective analyses on full-dose sequential and concurrent chemo-radiation are to be considered globally ambiguous and at risk of selection bias. Only specifically designed prospective studies will elucidate the real role and feasibility of combined chemo-radiotherapy in the treatment of locally advanced NSCLC in the elderly. Future perspectives on this topic include the evaluation of alternative schedules of chemo-radiotherapy, innovative radiation techniques more suitable to elderly patients, and the introduction of new, well-tolerated, molecularly targeted agents combined with standard treatments.
