BACKGROUND: @entity420 is an uncommon disease with poor prognosis. Therefore, characteristics and treatment strategies for @entity420 should be elucidated sufficiently, not only for surgery, but also for chemotherapy. @entity1 AND METHODS: Medical records were abstracted to identify @entity1 with @entity420 who were treated at the Iizuka Hospital, Fukuoka, Japan, between 2004 and 2014. The results of surgical treatment for stage II/III cases and the efficacy of chemotherapy for unresectable stage IV cases were investigated. RESULTS: The median @entity5 size was 25.6  19.2 mm, and @entity5 size was not associated with primary symptoms. Nine of the @entity1 were diagnosed with @entity5 and underwent surgical resection. The other three @entity1 were diagnosed with stage IV disease, and two out of those three cases received definitive chemotherapy. In two out of the nine resected cases, recurrence was observed; however, surgical resection of the recurrent @entity5 was associated with a good prognosis. In stage IV cases that received chemotherapy, survival durations of over 11 months were achieved. In contrast, overall survival in the stage IV case without chemotherapy was 3.3 months. CONCLUSION: Curative resection and definitive chemotherapy for unresectable cases are effective treatment strategies for @entity420 .
