Purpose: The most effective treatments in elderly patients with esophageal cancer remain a subject of debate. This multicenter phase 2 study was designed to evaluate the efficacy and toxicity of chemoradiation therapy (CRT) with docetaxel (DTX) in elderly patients with stage II/III (non-T4) esophageal cancer. Methods and materials: Patients ≥70 years of age with clinical stage II/III esophageal cancer received DTX at a weekly dose of 10 mg/m2 during 6 consecutive weeks and concurrent radiation therapy (60 Gy in 30 fractions). The primary endpoint was the 2-year survival rate, and the required number of enrolled patients was 37. Results: Between July 2008 and January 2011, 16 patients were enrolled. The study was prematurely closed because of slow accrual. Characteristics of the patients were as follows: median age, 77 years (range, 73-81); performance status 0/1, 4/12; and clinical stage IIA/IIB/III, 3/4/9. Of the 16 patients, 14 (87.5%) completed the CRT. The 2-year survival rate was 62.5% (90% confidence interval [CI], 42.5-82.5). The median survival time was 27.7 months (95% CI, 23.3-32.2 months) and the median progression-free survival was 15.2 months (95% CI, 5.4-25.0 months). Seven patients achieved complete response, resulting in a complete response rate of 43.8% (95% CI, 19.8-70.1). Grade 3 or higher acute toxicities included esophagitis (31.3%), anorexia (12.5%), leukopenia (6.3%), neutropenia (6.3%), thrombocytopenia (6.3%), mucositis (6.3%), and infection (6.3%). Grade 3 or higher late toxicities included esophagitis (12.5%), pleural effusion (12.5%), pneumonitis (6.3%), and pericardial effusion (6.3%). Conclusions: CRT with DTX might be a treatment option for elderly patients with stage II/III esophageal cancer, particularly for patients who are medically unfit for surgery or cisplatin-containing therapy. However, further improvements of this therapy are required to decrease the incidence of esophagitis. |
