[Successfully resected an isolated extraperitoneal @entity3 of sigmoid XXXX --a case report].

@entity1 @entity5 @entity787 @entity730 @entity3 @entity694 @entity1487
We herein report an extremely rare operative case of an isolated extraperitoneal @entity3 of @entity694 . A female @entity1 had undergone a sigmoidectomy for ileus due to sigmoid @entity694 when she was 40 years old. Peritoneal @entity3 , 5 mm in diameter, was on the sigmoid colon mesentery and she was histologically diagnosed as Stage IV. She received @entity1487 -based adjuvant chemotherapy for 24 months. Serum @entity787 increased gradually from 36 months after the operation, and CT scan demonstrated bilateral @entity5 . Bilateral oophorectomy was performed at 44 months after the operation. Serum @entity787 decreased temporarily, but increased again. Serum @entity787 increased in spite of giving UFT/LV, so we changed to mFOLFOX6 therapy. Serum @entity787 decreased until it reached to a normal range after 9 courses, and stopped mFOLFOX6 therapy. Four months later, serum @entity787 increased again and PET-CT demonstrated a 3 cm mass with @entity730 in pelvic, and accumulation of FDP. Serum @entity787 decreased until it reached to a normal range after a resection of extraperitoneal mass. A histological examination of the @entity5 revealed a moderately differentiated @entity694 . She has been well without recurrence 77 months after the first operation.
