[A Case of Cecal Cancer with Liver and Lung Metastases That Maintained Long Stable Disease by TFTD and Bevacizumab Chemotherapy].

The patient was a 69-year-old female diagnosed with cecum cancer, pMP, pN1, sH1, sP0, cM0, fStage IV. A laparoscopic cecal resection with D3 dissection was performed against the primary cecal cancer in January 2015. The histological diagnosis was moderately differentiated adenocarcinoma>mucinous adenocarcinoma, ly1, v0, RAS wild type(not known to start chemotherapy for primary treatment). Liver metastasis is very likely to invade the inferior vena cava, so the liver metastasis was judged unresectable, and mFOLFOX6 and bevacizumab(Bmab)chemotherapy was performed. After 4 courses of chemotherapy, the patient exhibited progressive disease(PD)and was transitioned to a secondary treatment with FOLFIRI plus panitumumab(Pmab)therapy. Lung metastases was observed(PD)upon computed tomography after 16 courses. Therefore, salvage line chemotherapy with TFTD and Bmab was performed. Long stable disease(SD)was obtained by the salvage line chemotherapy with TFTD and Bmab. We suspect that the effects of TFID increased in combination with Bmab. Moreover, the TFTD and Bmab chemotherapy was performed relatively safely.
