简要总结
Since multiple studies have demonstrated that PET can identify responders and non-responders to induction chemotherapy, using FDG-PET imaging to guide treatment decisions has prompted interest in clinical practice. The aim of this study was to evaluate whether changing chemotherapy regimen during radiation based on PET response to induction chemotherapy can improve clinical complete response (cCR) in patients with unresectable esophageal squamous cell carcinoma (ESCC).
详细描述
A total of 216 patients with baseline PET scan were randomized to one of 2 induction chemotherapy arms: paclitaxel/cisplatin (TP) on days 1, 22 or FOLFOX (oxaliplatin, leucovorin, 5-FU) on days 1, 15, 29. Repeat PET was performed on days 36-42 and changes in max standardized uptake value (SUVmax) from baseline were assessed. Using a predefined cut-off value of a 35% decrease in SUVmax, PET responders (≥35% decrease in SUVmax) continued on the same chemotherapy regimen during radiotherapy, whereas PET non-responders (<35% decrease in SUVmax) crossed over to an alternative chemotherapy regimen concomitantly with radiation. All patients received external-beam radiation using intensity-modulated radiotherapy. The prescribed dose is generally 50-60 Gy in 25-28 fractions, 5 days per week.

研究组 & 干预措施
TP Arm
Patients with baseline PET scan assigned to this Arm will receive two cycles of 3-weekly schedule of induction chemotherapy with paclitaxel/cisplatin (TP), consisting of paclitaxel 150 mg/m2 on day 1 and cisplatin 75 mg/m2 on day 1. Repeat PET was performed on days 36-42 and changes in SUVmax from baseline were assessed. PET responders (≥35% decrease in SUVmax) continued on the same chemotherapy regimen during radiotherapy, whereas PET non-responders (<35% decrease in SUVmax) crossed over to FOLFOX regimen concomitantly with radiation. All patients received external-beam radiation using intensity-modulated radiotherapy. The prescribed dose is generally 50-60 Gy in 25-28 fractions.
