Apatinib Combined with Irinotecan in the Treatment of Advanced Small-Cell Esophageal Carcinoma: A Case Report.

Chemotherapy is the mainstay of treatment for advanced small cell esophageal carcinoma (SCEC) characterized by poor prognosis. Preclinical studies demonstrated that apatinib has the potential to enhance the efficacy of conventional chemotherapeutic drugs and reverse multidrug resistance (MDR). This report described the application of apatinib combined with irinotecan as the third-line treatment for advanced SCEC in a 54-year-old male patient. His symptoms of upper abdominal pain and distension were ameliorated notably after the combination therapy. Computed tomography (CT) examination revealed the treatment efficacy was partial response (PR). The progression-free survival (PFS) and overall survival (OS) were 12.5 months and 28 months, respectively. The treatment-related toxicity was manageable. Apatinib combined with chemotherapy may serve as a new treatment choice for advanced SCEC patients. However, further studies should be conducted to confirm the therapeutic value of this combination regimen in advanced SCEC.
