4.Role of 18F 2-fluoro-2-deoxyglucose Positron Emission Tomography in Upper Gastrointestinal Malignancies.
The Korean Journal of Gastroenterology 2013;61(6):303-306
The 18F 2-fluoro-2-deoxyglucose (FDG) PET/CT scan is an imaging modality used in the management of patients with various types of malignancies. 18F-FDG PET/CT has demonstrated significant efficacy in the staging and detection of metastatic disease in malignancies of the gastrointestinal tract. The assessment of the metabolic response to chemotherapy and improvements of overall survivals in malignancies of esophagus and stomach has been demonstrated in several studies. This review focuses on the role of 18F-FDG PET/CT scan in staging, metastasis, predict of recurrence and assessment of metabolic response in malignancies of the upper gastrointestinal tract.

OBJECTIVE: Neuroendocrine cervical carcinoma is a rare subtype of cervical cancer. These tumors exhibit an aggressive behavior with early regional lymph node and distant metastases. The purpose of our study was to describe five cases of neuroendocrine cervical-vaginal carcinoma and to discuss the potential of the 2-[18F] fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography (18F-FDG PET/CT) scan for the detection of this rare malignancy. MATERIALS AND METHODS: Five cases of cervical-vaginal neuroendocrine tumor were retrospectively collected, during a two year (from September 2009 to August 2011) period in our hospital. The clinical staging distributions were International Federation of Gynecology and Obstetrics (FIGO) stage IB2 (1 of 5), stage IIA (3 of 5) and stage IVA (1 of 5). RESULTS: Two cases (cases 1 and 4) were restaged after 18F-FDG PET/CT scan in the initial staging process. Post-treatment 18F-FDG PET/CT scans, in three patients, revealed positive findings for tumor recurrence or lymph node metastases. Two patients (cases 2 and 3) died of tumor within two years. CONCLUSION: 18F-FDG PET/CT scan is a useful tool in cervical-vaginal neuroendocrine tumor. In its initial staging, the 18F-FDG PET/CT scan may help assess the possible nodal involvement or early hematogeneous spreading. We can also use the 18F-FDG PET/CT to detect local recurrence and to evaluate the treatment response after clinical manipulation.

Most cases of accessory spleen show similar features as normal spleen in imaging studies. However, some accessory spleen has unusual scan feature which can be misdiagnosed. We present a case of intrapancreatic accessory spleen that was discovered incidentally during a workup for abdominal pain in a 47-year-old woman. CT and MRI revealed a different enhancing pattern from that of the spleen. Further evaluation with endoscopic ultrasonography failed to identify the pancreatic mass. Therefore, it was surgically removed and diagnosed pathologically as an accessory spleen.

Primary lung cancer is a leading cause of cancer-related deaths in Korea. Approximately 50% of patients have metastatic disease at the time of presentation. The preferential sites of extrapulmonary spread include lymph nodes, liver, brain, adrenal glands, and bones. Gastrointestinal metastasis from primary lung cancer is extremely rare and only a few case reports have been published. Herein, we report a case of metastatic colon cancer from primary lung adenocarcinoma, presenting multiple cecal polypoid masses.

The objective of this study was to evaluate the feasibility of sentinel lymph node biopsy by using a radiotracer lymphatic mapping technique in patients with squamous cell carcinoma of the oral cavity, and the diagnostic value of this technique. We studied twenty patients with previously untreated squamous cell carcinomas of the oral cavity and N0 necks. After the peritumoral injection of 99mTc filtered tin colloid preop-eratively, lymphoscintigraphy and intraoperative mapping using a gamma detector were performed to localize sentinel nodes. An open biopsy of the sentinel node was followed by complete neck dissection. We identified the sentinel nodes in 19 of 20 patients (95.0%) by lymphoscintigraphy and in all (100%) by intraoperative gamma detector. In all cases, the status of the sentinel node accurately predicted the pathologic status of the neck with the false negative rate being 0%. The negative predictive value for the absence of cervical metastases was 100%. In conclusion, our radio-localization technique of sentinel nodes using 99mTc filtered tin colloid in N0 squamous cell carcinomas of the oral cavity is technically feasible and appears to accurately predict the presence of the occult metastatic disease.
