Popis: In Japan, neoadjuvant chemotherapy followed by esophagectomy has become the standard treatment for resectable advanced esophageal cancer. However, there are few reports on the utility of fludeoxyglucose( FDG)-positron emission tomography (PET) in such cases so far. In this study, we analyzed the utility and drawbacks of FDG-PET in patients who underwent neoadjuvant chemotherapy followed by surgery. Thirty-seven patients with cStage II or III thoracic esophageal cancer who received 2 courses of combination chemotherapy with 5-fluorouracil and cisplatin followed by surgery were enrolled this study. The maximum standardized uptake value (SUVmax) in the main lesion significantly decreased after chemotherapy (38.6%), and there was a greater decrease in SUVmax in patients with downstaging. Following chemotherapy, the esophageal lesions were not detected by FDG-PET in 6 patients. However, in these patients, the histopathological diagnosis of the resected specimens revealed that the cancer cells persisted. The SUVmax increased after chemotherapy in 5 patients, and in 4 of 5 patients recurrent disease was observed. In conclusion, we should understand the characteristics of FDG-PET in esophageal cancer after neoadjuvant chemotherapy and use it precisely.
