[A case wherein bevacizumab/XELOX combination therapy was remarkably effective for the treatment of extensive dissemination in advanced colon cancer, and the primary lesion could be resected].
Here, we report a case wherein bevacizumab/XELOX combination therapy was remarkably effective for the treatment of a patient with unresectable advanced cecum cancer and carcinomatous peritonitis. A 52-year-old man was diagnosed with cecum cancer with extensive carcinomatous dissemination. He underwent open laparotomy, and the findings indicated a unresectable cecal tumor attached to the retroperitoneum; therefore, ileo-transverse colostomy was performed. After 6 courses of bevacizumab and XELOX therapy, the primary tumor as well as ascites and carcinomatous dissemination had disappeared, and a marked decrease in the serum carcinoembryonic antigen(CEA)level was noted. However, subsequently, positive emission tomography/computed tomography(PET/CT)indicated a recurrence of the primary tumor. Therefore, ileocecalectomy and D2 lymph node dissection were performed. Thus, we believe that bevacizumab/XELOX therapy may be useful as neoadjuvant chemotherapy for the treatment of advanced colon cancer with peritonitis carcinomatosa.
