Early colon cancers detected by FDG-pet: a report of two cases with immunohistochemical investigation

Increased glucose uptake is one of the metabolic characteristics of tumor cells. 18F-fluorodeoxyglucose (FDG)-positron emission tomography (FDG-PET), a technique that is used widely to study this altered glucose metabolism in tumors, allows the detection of various types of malignancy. We present herein two cases of early colon cancers detected incidentally by FDG-PET. The technique was used as part of the screening examinations for preoperative staging, and for postoperative follow-up. In both cases, the lesions were removed by colonoscopic polypectomy, with no complications. Moreover, we confirmed the existence of altered glucose metabolism in the resected specimen by immunohistochemical staining using an antibody raised against Glut1. Immunohistochemically, Glut1 was expressed in vitro in both of the lesions, supporting the positive FDG-PET result obtained in vivo. To our knowledge, this is the first report to describe in vitro Glut1 expression and in vivo tumor detection using FDG-PET in colorectal carcinoma.     

Evaluation of Ki-67 and p53 expression in primary and repeated liver metastases of GISTs

There has been little research evaluating changes related to tumor cell proliferation between primary and metastatic tumors of gastrointestinal tumors in the same case. We herein report the case of a 50-year-old woman with a gastric gastrointestinal stromal tumor (GIST), who developed metastatic liver tumors three times in the 7 years after proximal gastrectomy for GIST. The primary and all the metastatic liver tumors, except the second, showed fascicular/storiform architecture and the short spindle cell type. The diffuse epithelioid cell proliferation was observed in the second metastatic liver tumor. Although the immunostaining pattern with respect to GIST differentiation markers had been preserved in the primary tumor as well as in all of the metastatic tumors, the latter showed weaker positivity of both Ki-67 and p53 than the primary GIST. The primary tumor showed diffuse positive p53, and the highest value of Ki-67 labeling index (LI) among them. The metastatic liver tumors showed focal, negative or sporadic positive appearances of p53, however, Ki-67 LI were scattering among them. Immunohistochemical assessment of Ki-67 LI and p53 might be useful for evaluating changes related to tumor cell proliferation between primary and metastatic tumors of GISTs.     

Two-staged hepato-pancreatoduodenectomy and interventional pancreaticojejunostomy

Two-staged pancreatoduodenectomy, including exteriorization of the pancreatic juice and second-look pancreaticojejunostomy, has been recommended for high-risk patients to avoid pancreatic leakage, which often causes intra-abdominal hemorrhage. We present a new technique of interventional pancreaticojejunostomy under both fluoroscopy and endoscopy without second-look laparotomy. A 77-year-old woman with local recurrence and liver metastasis from colon cancer underwent hepato-pancreatoduodenectomy with the external drainage of pancreatic juice via the pancreatic duct tube without pancreaticojejunostomy. Two months later, the jejunum was punctured with the insertion of a 5-F needle-knife into the pancreatic fistula during endoscopic observation of jejunal lumen, followed by the insertion of two 0.35-inch guidewires into the jejunum and the pancreatic fistula. Finally, a 10-Fr stenting tube was placed between the jejunum and the pancreatic fistula. No complications developed.
