[A Case of Heterochronic Ovarian Metastasis from Sigmoid Colon Cancer after Sigmoidectomy Treated with CapeOX That Included Bevacizumab].
The patient was a 41-year-old woman. When she was 39 years old, she had undergone laparoscopic high anterior resection for sigmoid colon cancer without adjuvant chemotherapy. Histologically, the surgical specimen was type 2, tub2, pT4a (SE), pN0, int, INF b, ly1, v1, and pStage II. Nine months after the operation, she suffered from abdominal fullness. Laborato- rydata showed elevation of tumor markers: the CEA level was 6.48 ng/mL, the CA19-9 level was 89.70 U/mL, and the CA125 level was 662 U/mL. Computed tomographyrevealed bilateral ovarian tumors and lung and peritoneal nodules with massive ascites. Chemotherapywas started with a regimen consisting of capecitabine plus oxaliplatin(CapeOX)that included bevacizumab. After 4 courses, the sizes of the lung and peritoneal nodules had decreased and the amount of ascites was almost zero. However, the ovarian tumors had increased in size and her sense of abdominal fullness had not improved. Bilateral oophorectomy with hysterectomy was performed to alleviate her symptom. Immunohistochemically, the resected ovarian tumors were negative for cytokeratin 7 and positive for cytokeratin 20. CapeOX with bevacizumab was then resumed. However, the lung tumor had graduallyincreased in size, and therefore, she underwent partial resection of the lung for the metastatic lung tumor.
