[A case of advanced descending colon cancer with peritoneal dissemination responding to weekly high-dose l-leucovorin/5-fluorouracil combination therapy].
We report a case in which l-leucovorin/5-fluorouracil (l-LV/5-FU) combination therapy was remarkably effective for non-resectable advanced descending colon cancer with carcinomatous peritonitis. A 65-year-old man complained of severe abdominal distension, abdominal pain and pulmonary failure, and was diagnosed as having ileus due to descending colon cancer. The patient underwent urgent open laparotomy to release the ileus condition on March 5, 2002. During the laparotomy, we established a diagnosis of nonresectable descending colon cancer accompanied by severe peritoneal dissemination and therefore performed only double-barreled transverse colostomy. The postoperative course was very good. Pathological examination of omental dissemination demonstrated moderately differentiated adenocarcinoma and cytology of ascites was class II. The levels of serum CEA and CA19-9 were within the normal ranges. l-LV/5-FU therapy was initiated postoperatively. Seven cycles of this chemotherapy regimen was performed with no apparent side effect during the treatment. There was no postoperative accumulation of carcinomatous ascites. The patient gained 15 kg compared with body weight admission. On abdominal computed tomography (CT), the primary lesion of the colon decreased 98% and there was no ascites found. To date, there has not been any sign of recurrence during the 19 months of follow-up after this therapy, and we are currently discussing closure of the transverse colostomy. This therapy may be useful for patients with advanced colon cancer accompanied by peritoneal dissemination.
