[A case of gastric cancer with extraordinary liver metastasis effectively treated by adjuvant chemotherapy].

This was an extraordinary liver metastasis case with complication when the patient, a 70-year-old male, was diagnosed with stomach cancer for the first time. However, the patient has been in remission and is a long-term survivor due to an active chemotherapy after the operation. His chief complaints were stomachache and a loss of weight. He was diagnosed with stomach cancer by endoscopy. During the surgery, the mass was found to be 3 QFB palpable caused from hepatomegaly. The liver dysfunction was revealed in the blood biochemistry inspection. The abdominal CT revealed that the stomach cancer had spread to the whole liver. Distal gastrectomy was performed on May 22, 1997. In pathological findings, the tumor was diagnosed as a well-differentiated adenocarcinoma. Final findings: M, type3, T3 (SE), N2, H3, P0, CY0, and Stage IVb. The 5-FU based chemotherapy was performed and a complete response was temporarily obtained. However, it has recurred one year later and two or more kinds of chemotherapy have continued. He is alive for more than 7 years and comes to our hospital as an outpatient.

[The 5-fluorouracil hepato-arterial infusion with oral UFT therapy for the hepatic and extra hepatic metastases of colorectal cancer].

BACKGROUND: The 5 fluorouracil hepato-arterial infusion (5-FU HAI) therapy has a good effect on the liver metastases of colorectal cancer. To gain the antitumor effect of the extra-hepatic lesion, an oral UFT was combined with 5-FU HAI (pharmacokinetic modulating chemotherapy, PMC) to enhance the plasma 5-FU concentration. METHODS: UFT (200-400 mg/day) was orally administered daily and a continuous infusion of 5-FU (1,000-1,500 mg/5 h) was given once a week. Eight patients were treated with this regimen. Five of the eight have extra-hepatic lesions with liver metastases when this treatment was started. The response, time to progression, survival, and toxicity were detected. RESULTS: Four of the five patients with extra-hepatic lesion were evaluated. The response rate was 50% (1 CR, 1 PR, and 2 SD). For the liver metastases, the response rate was 62.5% (1 CR, 4 PR, 2 SD, and 1 PD). Grade 2 leukopenia was found in 1 patient. CONCLUSIONS: The 5-FU HAI with an oral UFT therapy had a good effect on the extra-hepatic lesions as well as hepatic metastases of colorectal cancer.

[A case of gastric cancer with peritoneal dissemination which shows a remarkable efficacy by a weekly administration of paclitaxel intraperitoneally].

We treated a 65-year-old female with gastric cancer who underwent peritoneal dissemination after 6 successive weeks of paclitaxel intraperitoneal therapy (90 mg/body), and obtained a disappearance of ascites and a reduction of the primary carcinoma. Operative findings: U ant, type 5, 26x20 mm, por, T2, n1(+), H0, P0, CY0, M0, stage II, and grade 2. A weekly paclitaxel intraperitoneal therapy could be a useful for both peritoneal dissemination and the primary carcinoma of advanced gastric carcinoma.

[A case of gastric endocrine cell carcinoma with neck lymph node metastasis resected after neoadjuvant chemotherapy].

A relatively rare case of gastric endocrine cell carcinoma was reported. The prognosis of this disease appears to be very poor due to its rapid rate of growth and invasiveness. A 75-year-old woman underwent a gastric endoscopy because the patient complained of an appetite loss. A gross Borrmann 3 type lesion in the greater curvature of the fornix was found. Biopsy specimens showed endocrine cell carcinoma. Abdominal CT examination revealed metastases in left neck and paraaortic lymph nodes. The serum sample showed an elevation of NSE level to be 53. A combination chemotherapy was performed using cisplatin and etoposide, which resulted in remarkable reduction of the main tumor two months later. The total gastrectomy associated with D2 lymph node dissection was performed. However, abdominal tumor was observed again in a month and it progressed rapidly. No clear response to the chemotherapies with cisplatin/etoposide or paclitaxel was found. The patient died 5 months after the operation.

[A case of liver and lung metastases of rectal cancer responding well to 5-FU hepato-arterial infusion (HAI) with combined use of oral UFT].

We have studied the pharmacokinetics of 5-FU hepato-arterial infusion (HAI) with combined use of oral UFT for colorectal cancer cases previously. The plasma 5-FU concentration in cases of 5-FU HAI plus UFT is 1.5-6 times as high as with 5-FU HAI only. We report a rectal cancer case with liver and lung metastases treated successfully with this protocol. A 75-year-male underwent low anterior resection for rectal cancer as Rab, 3.5 x 3 cm, well, ai, n2, P0, H3, M1 on March 26, 2002. For synchronous hepatic and lung metastases, he received weekly 5-FU 1,000 mg HAI, UFT 4T 2 x postoperatively. As a result, liver and lung metastases disappeared over 6 months. We recommend weekly 5-FU HAI with combined use of UFT, which can be more effective not only for liver metastases but also for extra-hepatic lesion of colorectal cancer.

[Complication after self expandable metallic stent for esophageal cancer].

Major complications after placement of esophageal stent and airway stent were reviewed and evaluated. Four patients, including two patients with perforations and two patients with fistula formation, developed major complications after placement of a self expandable metallic stent. Two patients underwent additional radiation to improve stricture after stent placement. In one patient, stent placement was selected to improve esophageal stricture that occurred after radical radiation therapy. In one patient, migration of stent into the lesion caused a perforation. It can be concluded that additional radiation after stent placement increases the risk of complication. Stent migration also can lead to the risk of perforation.
