Background: We carried out a phase II study to evaluate the efficiency and safety of the combination of nanoparticle albumin bound-paclitaxel (nab-paclitaxel) and cisplatin as preoperative chemotherapy for locally advanced esophageal squamous cell carcinoma (ESCC)
Results: From Oct 2011 to Dec 2012, 35 patients were enrolled and received neoadjuvant chemotherapy. Thirty patients underwent surgery and achieved a 100% R0 resection. Pathological complete response (pCR) rate was 13.3% and near pCR rate was 6.7%. Down-staging was achieved in 19 patients. With median follow-up of 37.8 months, 16 patients were still alive. One-, 2- and 3- year overall survival (OS) rate was 90.0%, 70.0% and 43.3%, respectively. This treatment resulted in a median disease-free survival (DFS) of 34.7 months and a median OS of 37.8 months. Median DFS and OS of down-staged patients were significantly longer than those of non-downstaged patients. The grade 4 toxicities during neoadjuvant chemotherapy were limited to neutropenia (2.9%) and vomiting (2.9%).
Methods: Patients with locally advanced ESCC (stage IIA to IIIC) and performance status 0-1 were enrolled and received two cycles of nab-paclitaxel (100 mg/m2) on day 1, 8, 22 and 29, and cisplatin (75 mg/m2) on day 1 and 22, followed by resection. Two cycles of adjuvant chemotherapy with the same regimen were given. Postoperative radiotherapy was permitted and decided by radiation therapist.
Conclusion: Weekly nab-paclitaxel with three-weekly cisplatin seems effective and safe as a neoadjuvant chemotherapy strategy for locally advanced ESCC. Down-staged patients have favorable outcome.
