[A Patient with Rectal Cancer and Multiple Lung Metastases Treated with XELOX plus Bevacizumab (Bev) Therapy]

The patient was a 76-year-old woman who underwent laparoscopic-assisted low anterior resection for rectal cancer. According to the Japanese classification of colorectal carcinoma (8th Edition), the tumor was tub1, ly0, v0, and pStage Ⅰ (pT1bN0M0), Cur A. She received no adjuvant chemotherapy. A chest CT scan obtained 42 months after the surgery revealed 3 lung metastases in the left lung, with the biggest measuring 12 mm; the CA19-9 level was elevated to 72U/mL (normal≦38 U/mL). She declined surgery for the recurrence. She was treated with XELOX plus bevacizumab (Bev) therapy. Before XELOX plus Bev, the 3 lung metastases had enlarged, with the biggest now measuring 15 mm, and the CA19-9 level was elevated to 166 U/mL. After 4 cycles, the lung metastases decreased in size and the CA19-9 level decreased to 4 U/mL. We did not perform pulmonary resection or additional chemotherapy. No progression of the recurrent tumors was detected on CT after 2 years, and the CA19-9 level was within the normal range. XELOX plus Bev therapy may be effective for unresectable pulmonary metastasis from colorectal cancer.
