Tolerance and benefits of treatment for elderly patients with limited small-cell lung cancer

Objectives: Over 20% of all newly diagnosed Dutch patients with small-cell lung cancer (SCLC) are aged >= 75 years. Uncertainties still exist about safety and efficacy of chemotherapy and chemoradiation in elderly patients. We evaluated the association between patient characteristics and (completion of) treatment and also evaluated toxicity, response and survival in elderly patients with SCLC. Materials and Methods: Population-based data from patients aged 75 years or older and diagnosed with limited SCLC in 1997-2004 in The Netherlands were used (N = 368). Additional data on co-morbidity, motive for deviating from guidelines, grades 3-5 toxicity, response and survival were gathered from medical records. Results: Although only relatively fit elderly were selected for chemotherapy, almost 70% developed toxicity, leading to early termination of chemotherapy in over half of all patients. Median survival time was 6.7 months, but differed strongly according to type and completion of treatment (13.5 months for chemoradiation, 7.1 months for chemotherapy, 2.9 months for best supportive care, 11.5 months for patients receiving at least 4 cycles of chemotherapy and 3.6 months for less than 4 cycles). Conclusion: Although toxicity rate was high and many patients could not complete the full chemotherapy, those who received chemotherapy or chemoradiation had a significantly better survival. We hypothesize that a better selection by proper geriatric assessments is needed to achieve a more favourable balance between benefit and harm. (C) 2013 Elsevier Ltd. All rights reserved
