Patient-reported outcomes (PROs) in NRG Oncology RTOG 0436: a phase III trial evaluating the addition of cetuximab to paclitaxel, cisplatin, and radiation for esophageal cancer treated without surgery.

ABSTRACT:

Purpose/objectives

NRG/RTOG 0436 evaluated cetuximab added to chemoradiation (CRT) for non-operative esophageal cancer management. PRO objectives assessed improvement in the FACT-Esophageal cancer subscale (ECS), version 4, with cetuximab, and if improved ECS correlated with clinical complete response (cCR).

Materials/methods

Patients were randomized to cisplatin/paclitaxel/radiation ± cetuximab. Overall survival (OS) was the primary endpoint, with a 420 patient target, which also provided 82% power to detect ≥ 15 increase in the proportion of cetuximab patients with ECS improvement from baseline to 6-8 weeks post-CRT; α = 0.05, using a χ² test. Improvement in ECS and its Swallowing and Eating Indices (SI, EI) was defined as 5, 4 and 2 point increases, respectivel
