Single-agent chemotherapy with vinorelbine for pretreated or metastatic squamous cell carcinoma of the esophagus

At least half of the patients with squamous cell carcinoma of the esophagus (SCCE) present at diagnosis with metastatic disease, and most patients in a locally advanced phase will develop metastases despite potentially curative local therapy. Thus, the majority of patients with SCCE will become candidate for palliative chemotherapy. Only a few drugs have demonstrated moderate activity (>15%) against SCCE. The main purpose of this phase II trial was to assess the activity of vinorelbine, a semisynthetic vinca alkaloid with a wide spectrum of action, in advanced or relapsed SCCE.
