[A case of advanced gastric cancer with abdominal para-aortic lymph node metastasis successfully treated with FLP therapy].

A 73-year-old woman was admitted to our hospital in June 1998, suffering from upper abdominal pain. The upper G-I series and endoscopic examination revealed stenosis of the pylorus and antrum by a type 2 cancer, and a poorly differentiated adenocarcinoma and a signet-ring cell carcinoma were confirmed on endoscopic biopsy. A CT scan showed the enlargement of many regional and abdominal para-aortic lymph nodes. FLP therapy combined with cisplatin (50 mg/m2 drip i.v., day 1-8), 5-fluorouracil (333 mg/m2 drip i.v.) and leucovorin (30 mg/body i.v., day 1-8) was planned for neoadjuvant chemotherapy (NAC) in order to reduce or eliminate the tumor and increase curability. After two cycles of the FLP therapy, the tumor size shrunk remarkably and the enlargement of the para-aortic lymph nodes disappeared. Distal gastrectomy with extended lymphadenectomy and cholecystectomy was performed. The histological findings of the primary tumor and metastatic lymph nodes demonstrated massive cancer cell degeneration such as pycnosis and vacuolation, xanthogranulomatous inflammation and dense fibrosis. The effect of NAC was judged to be grade 2 histologically. FLP therapy is an effective and safe regimen for NAC.
