Resection of Paraaortic Lymph Node Recurrence Wherein Complete Response to Bevacizumab Was Observed after Surgery for Sigmoid Colon Cancer

We report a case of resection of a paraaortic lymph node recurrence, wherein complete response to bevacizumab was observed. Our patient was a 50-year-old woman who had a paraaortic lymph node recurrence during adjuvant chemotherapy with FOLFOX 6 months after surgery for sigmoid colon cancer. She was treated with chemotherapy consisting of FOLFOX plus bevacizumab/FOLFIRI plus bevacizumab, which suppressed progression of the periaortic lymph node recurrence. She underwent surgery for the paraaortic lymph node recurrence, and the pathologic result was complete response. We report that bevacizumab was effective for her paraaortic lymph node recurrence.
