Abstract 2083
Background
Patients with esophageal cancer commonly suffer from dysphagia, leading to nutritional problems and impaired quality of life. Self-expanding metallic stents (SEMS) is frequently used in the palliative setting providing a rapid but short-term relief. In this phase II study we assessed a novel first-line treatment schedule with short-course radiotherapy followed by chemotherapy with the primary aim to achieve a long-term improvement of dysphagia.
Methods
Patients with dysphagia due to adenocarcinoma of the esophagus or esophagogastric junction, not eligible for curative treatment, were recruited. Treatment consisted of radiotherapy (5 x 4 Gy) followed by 4 cycles of chemotherapy (FOLFOX regimen). Dysphagia was assessed using a 5-grade scale and a response was defined as an improvement from baseline with at least one step in dysphagia score during the study treatment period or within 4 weeks after end of study treatment. Response of the primary tumour was assessed using endoscopy and PET imaging.
Results
From October 2014 to May 2018 a total of 29 patients were enrolled. Median age was 68 years. WHO PS (0/1/2); 10/12/7, female/male; 6/23, stage III/IV; 3/26, dysphagia score (0/1/2/3/4); 0/15/6/7/1. In the per-protocol (PP) population of 23 patients (treated with at least 4 fractions of radiotherapy and 2 cycles of chemotherapy) the rate of dysphagia improvement was 91%, the median time to improvement was 2.0 months (95% CI: 1.5, 2.5) and the median duration of improvement was 12.2 months (95% CI: 6.2, 18.2). 5 patients received SEMS during follow-up. In the PP population the endoscopic response rate was 78% with 22% complete responders, the metabolic response rate of the primary tumor was 61% with 30% complete responders. Median overall survival was 16.0 months (95% CI: 9.6, 22.5). In the safety population (28 patients who started treatment) the most frequent grade 3-4 adverse events were neutropenia (32%), infection (25%), pain (14%), esophagitis (11%) and anorexia (11%).
Conclusions
Palliative short-course radiotherapy followed by chemotherapy is a promising treatment strategy that can provide long-lasting relief of dysphagia in patients with esophageal adenocarcinoma.
