Abstract
We report a case of G-CSF producing ascending colon cancer. A 44-year-old man visited the hospital because of pyrexia and right hypochondralgia, and was admitted for examination of a high inflammatory score.
Multiple liver tumors and ascending colon wall thickening were observed, but infectious diseases were ruled out by computed tomography(CT). We diagnosed the condition as ascending colon cancer based on colonoscopic examination. Right hemicolectomy and biopsy of the liver were performed, and was ultimately diagnosed as G-CSF producing colon cancer and multiple liver metastases based on the histopathological examination.
After the operation, pyrexia and the high inflammatory score continued. His general condition was getting worse, but we initiated chemotherapy (mFOLFOX6) because of his family's request, and combined with bevacizumab from the 3rd course. The patient left the hospital because his condition went into remission after the 4th course of chemotherapy, and continued the treatment as an outpatient. But he was rehospitalized for general fatigue presently. After admission, he lost consciousness suddenly and was diagnosed as having a serious cerebral infarction. A few days later he died, 4 months after the surgery.
