[A case of advanced rectal cancer responding to l-Leucovorin (LV)/5-fluorouracil( 5-FU) therapy as neoadjuvant chemotherapy].

We report a case in which l-Leucovorin/5-fluorouracil (l-LV/5-FU) therapy was remarkably effective for advanced rectal cancer as neoadjuvant chemotherapy (NAC). A 54-year-old man complained of bloody stool and constipation,and was diagnosed as having stage IIIB advanced rectal cancer with N2 lymphnode metastases on July 31, 2003. Two cycles of NAC by l-LV/5-FU therapy were performed.

[A case of cecal cancer with multiple liver metastases responding to irinotecan (CPT-11)/cisplatin (CDDP) combination therapy for elevation of CA19-9 after complete response (CR) by l-leucovorin(LV)/5-fluorouracil(5-FU) therapy].

A 62-year-old woman complained of abdominal pain and diarrhea from February 2, 2002. She was diagnosed with advanced cecal cancer with simultaneous multiple liver metastases. The serum level of CA 19-9 was 420 U/ ml.

[A case of advanced gastric cancer with direct invasion of the transverse colon responding to paclitaxel/5'-DFUR combined therapy].

A 50-year-old man was diagnosed with non-resectable scirrhous gastric cancer of antrum accompanied with colon ileus due to direct invasion of the transverse colon. As the ileus improved after cecostomy, chemotherapy with TS-1/cisplatin(CDDP) was performed. Because of no response, 4 cycles of paclitaxel (PTX)/doxifluridine (5'-DFUR) therapy was performed as second-line chemotherapy.

[A case of recurrent stomach cancer treated with 5-fluorouracil responding to weekly paclitaxel therapy].

We report a patient with unresectable stage IV stomach cancer with metastasis to the paraaortic lymph nodes who achieved an effective response to neoajuvant chemotherapy, which allowed curability-B resection, and in whom weekly paclitaxel (TXL) therapy for postoperative recurrence was very effective in improving QOL. The patient was a 65-year-old man. After preoperative PMFE therapy, CEA decreased from 68.

[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.

[Complete response to treatment with low-dose FP therapy in a patient with stage IVB primary hepatocellular carcinoma with multiple lung and bone metastases].

We report a case in which low-dose FP (5-fluorouracil/cisplatin, 5-FU/CDDP) therapy was remarkably effective for stage IVB advanced hepatocellular carcinoma (HCC) with lung and bone metastases. 5-FU of 250 mg/body/day was continuously infused over 24 hours and CDDP of 10 mg/body/day was infused over 30 minutes from day 1 to day 5 in a week. Administration was continued for 4 weeks as 1 cycle.
