Purpose:
Late course accelerated hyperfractionated (LCAF) radiotherapy (RT) is as effective as standard chemoradiotherapy for nonsurgical management of locally advanced esophageal squamous cell carcinoma (SCC). We have evaluated further the efficacy of concurrent LCAF RT and chemotherapy.
Methods And Materials:
In all, 111 eligible patients with esophageal SCC were randomized to receive LCAF alone (LCAF) or concurrent LCAF and chemotherapy (LCAT+CT) between March 1998 and July 2000. All patients received conventional fractionation irradiation of 1.8 Gy per day, to a dose of 41.4 Gy/23 fractions in 4-5 weeks, followed by accelerated hyperfractionated irradiation using reduced fields, 1.5 Gy/fractions twice a day, to a dose of 27 Gy in 18 days. Thus, the total dose was 68.4 Gy/41 fractions in 44 days. Fifty-four patients in the LCAF+CT arm had an additional four cycles of chemotherapy using cisplatin 25 mg/m(2) daily and fluorouracil (5-FU) 600 mg/m(2) daily on Days 1-3 every 4 weeks starting on the same day that LCAF was delivered.
Results:
The median survival was 23.9 months (95% confidence [CI], 20.1-27.7) for the LCAF arm and 30.8 months (95% CI, 17.6-44.1) for the LCAF+CT arm, respectively. Survival rates at 1, 3, and 5 years of the LCAF arm were 77%, 39%, and 28%, respectively, while those of the LCAF+CT arm were 67%, 44%, and 40%, respectively (p = 0.310). Grades 3 and 4 acute toxicities occurred in 46% and 25% of the patients in the LCAF arm and the LCAF+CT arm, respectively; 6% of the patients in the combined arm had Grade 5 acute toxicities, whereas none was noted in the LCAF alone arm.
Conclusions:
Late course accelerated hyperfractionation was effective for locally advanced esophageal SCC. There was a trend toward better survival among patients who received intensified treatment with concurrent chemotherapy. Further randomized studies with a larger number of patients should be carried out, but additional measures must be taken to reduce the higher mortality rate due to chemotherapy-related acute toxicities.
