title: [A Case of Pseudomyxoma Peritonei Derived from Cecum Colon Cancer with Long-Term Recurrence-Free Survival].
abstract: A 29-year-old woman was diagnosed with advanced cecum colon cancer, and right hemicolectomy was performed. The pathological findings showed stage Ⅲa disease, including moderately differentiated tubular adenocarcinoma>mucinous adenocarcinoma, pT3, pN1, cM0, and Cur A resection. The patient was treated with 5-FU plus l-LV adjuvant chemotherapy. Fourteen months after surgery, bilateral ovarian metastasis and ascites were found, and another surgery was performed, revealing that the abdominal cavity was filled with a gelatinous ascites. Under the diagnosis of pseudomyxoma peritonei, resection of both ovaries, abdominal lavage, and intraperitoneal administration of CDDP were performed, followed by S-1 plus CDDP treatment. Two years after the recurrence, peritoneal re-recurrence on the vaginal fornix was detected. A total hysterectomy, partial vaginectomy, and resection of disseminated peritoneal nodules were performed. The patient received mFOLFOX6 treatment postoperatively. To date, 8 years and 9 months after her re-recurrence, the patient is alive and without signs of a third recurrence.
