Abstract
PURPOSE: Neoadjuvant chemotherapy (NAC) followed by esophagectomy has become a standard treatment for esophageal squamous cancer (ESCC) in Japan. We used propensity-matching analysis to clarify the safety and efficacy of NAC in daily clinical practice. METHODS: We reviewed the medical records of 335 patients with clinical Stage II/III ESCC diagnosed between 2007 and 2012, including 191 who received preoperative NAC (NAC group) and 144 treated by upfront surgery (US group). After propensity score matching, there were 118 patients in each group. We compared the postoperative complications and long-term outcomes between the groups. RESULTS: Seven patients in the NAC group underwent replacement therapy. Complications occurred in 76 (68.5%) and 76 (64.4%) patients in NAC and US groups, respectively (p = 0.51), and severe complications occurred in 17 (22.4%) and 30 (39.5%) patients, respectively (p = 0.057). One (0.8%) and three patients (2.5%) from the US group died within 30 days and 90 days after surgery, respectively, but none of the patients from the NAC group died within the same period. The 5-year survival rate was 54.9% in the NAC group and 41.2% in the US group (p = 0.024). CONCLUSIONS: NAC is a safe and effective treatment to improve prognosis in the clinical setting.
