Abstract
Objective
To compare short-term outcomes between two- vs. three courses of neoadjuvant chemotherapy (NAC) to clarify the optimal treatment for esophageal squamous cell cancer (ESCC) in a multicenter, randomized, phase II trial.
Background
An optimal number of NAC cycles remains to be established for locally advanced ESCC.
Methods
Patients with locally advanced ESCC were randomly assigned to either two (N = 91) or three (N = 89) courses of DCF (70 mg/m2 intravenous docetaxel and 70 mg/m2 intravenous cisplatin on day 1, and a continuous 700 mg/m2 fluorouracil infusion for 5 days) every 3 weeks followed by surgery. We compared the two groups for perioperative parameters, adverse events, and the response to NAC.
Results
The two- and three-course groups showed similar completion rates and overall NAC dose reductions. Although the two-course group showed significantly lower overall grades 3–4 leukopenia and anemia compared to the three-course group, the two groups had similar overall toxicity rates. Postoperative complications were not significantly different between the two groups, except arrhythmia (13 vs. 0%, P = 0.0007). Only two postoperative in-hospital deaths occurred in the three-course group, due to sepsis following severe pneumonia. Compared to the two-course group, the three-course group was associated with a significantly better clinical response (42.9 vs. 65.2%, P = 0.0027) and a relatively higher rate of pathological complete response (9.1 vs. 15.3%, P = 0.212).
Conclusion
Both two- and three-course DCF regimens in the NAC setting seemed to be equally feasible in locally advanced ESCC patients. Additional DCF courses led to a better NAC response without increasing the incidence of adverse events or postoperative morbidity.
