[A case report--locally advanced XXXX was resected after chemotherapy].

@entity1 @entity788 @entity82 @entity353 @entity5 @entity448 @entity4420 @entity694 @entity6029
The case was a 36-year-old male whose chief complaints were @entity448 and @entity353 . Upper gastrointestinal endoscopy revealed circumferential stenosis in the fourth portion of the duodenum, while CT revealed a @entity5 with a diameter of 60 mm continuing as a single mass from the pancreatic body and tail to the fourth portion of the duodenum, and this was accompanied by findings that raised suspicions of circumferential invasion of the @entity6029 ( @entity6029 ). Based on these results and biopsy, the @entity1 was diagnosed with @entity788 that was considered to be unresectable. After performing gastrojejunostomy, we administered @entity4420 (40 mg/m2, day 1), CDDP (60 mg/m2, day 1), and S-1( 80 mg/m2, day 1-14) for 3 courses. The @entity5 response was PR and the images indicated the @entity6029 invasion was disappeared. We judged that the @entity5 could be gone by a resection while preserving the @entity6029 . In the surgical findings, the @entity5 continued as a single mass from the pancreatic body and tail to the third portion of the duodenum, and the surrounding area exhibited marked @entity82 . We performed a pancreatic tail resection along with combined resection of third and fourth portions of the duodenum, transverse @entity694 , and left adrenal gland. The case was diagnosed to be well-differentiated @entity788 with duodenal invasion. Cancer invasion was not observed in any of the stripped surfaces surrounding the pancreas. The T3, N1, M0, fStage III antitumor effects were mildly effective. In this case, the treatment was initially started by considering the case as one of @entity5 , but the final results of a pathological diagnosis revealed that it was @entity788 . However, either way, even though the case was unresectable before the chemotherapy performed for @entity5 was significantly effective for the @entity788 . Therefore, a resection became possible, and an R0 resection was also effective.
