    Abstract:
    The incidence of elderly patients with esophageal cancer (OC) is increasing as the population ages. Until now, the treatment strategy in these patients has been unclear. The aim of our study was to assess the efficiency and tolerance of treatment with radiotherapy alone (RT alone), single-agent-based concurrent chemoradiotherapy (CCRT-1), or double-agent-based concurrent chemoradiotherapy (CCRT-2) in elderly patients (≥65 years) with OC. A total of 271 patients with OC aged 65 years or older were included in this study. The median overall survival (OS), median progression-free survival (PFS), overall response rate (ORR), disease control rate (DCR), and treatment-related toxicities were assessed. The median OS time for all patients was 23.6 ± 2.3 months, with 2-year survival rates of 48.0 ± 3.0%. The median PFS time was 13.6 ± 1.3 months with the 2-year PFS rate was 33.0 ± 4.0%. Among patients who received CCRT-1, better OS, and PFS were found in patients who received docetaxel than in patients received fluorouracil and platinum. In a subgroup analysis, 118 patients who underwent RT alone had a median OS time of 15.6 ± 1.9 months and median PFS time of 10.4 ± 0.9 months. The median OS time of patients who received CCRT-1 was 28.8 ± 10.1 months compared with 27.8 ± 2.5 months for the patients treated with CCRT-2 (P = 0.537). The similar results were observed for median PFS, with 16.5 ± 3.2 months in the CCRT-1 group and 17.0 ± 2.0 months in the CCRT-2 group (P = 0.321). Grade ≥3 leukocytopenia and grade ≥2 weight loss during treatment occurred in 40.6% and 17.9% of patients, respectively, in the CCRT-2 group, which was higher than that observed in the CCRT-1 group. Our results suggested that CCRT could be considered as an acceptable treatment for elderly patients with OC. The CCRT-1 group presented with a lower incidence of treatment toxicities but comparable survival outcomes, compared to the CCRT-2 group. Docetaxel was superior to fluorouracil and platinum in terms of OS.
