RESUMO
Married couples share home environments and life style for years. In the case of colorectal cancer, an association with insulin resistance was reported. We determined the presence of the insulin-resistance syndrome (IRS, 1 or more of the following: body mass index of > 25 kg/m2, diabetes, or hyperlipidemia) in 84 colorectal cancer patients, of whom 61 patients (73%) had IRS. The incidence of the distal colorectal cancer, which has been declining in the United States, was significantly higher in the IRS group than in the non-IRS group (75.4 vs 52.2%, p = 0.0400). Some mechanisms may promote the progression of mucosal lesions to invasive cancers in the distal colorectum. There were no significant differences with respect to the age (64.6 +/- 9.4 vs 64.3 +/- 11.3 yr, p = 0.8298), height (159 +/- 9 vs 157 +/- 8 cm, p = 0.1375), and body mass index (22.2 +/- 3.6 vs 22.4 +/- 2.7 kg/m2, p = 0.6364) between the patients and their spouses. In 84 couples in whom colorectal cancer develops at least in one may then not illustrate the nursery rhyme: "Jack Sprat could eat no fat, His wife could eat no lean...". The spouses had been married for an average of 38 years, and in 30 spouses who had been followed in a colorectal cancer screening, 5 developed colorectal cancer. To diminish the incidence of colorectal cancer in Japan, we might advise screening colonoscopy to the spouses of colorectal cancer patients, or déjà vu all over again?

A 46 year-old male who was strictly diagnosed as having volvulus of the ileum based on the pre-operative information brought by computed tomography (CT) and helical (spiral) 3-dimensioned computed tomography was surgically treated. The post-operative course was satisfactory and the patient is now under observation without any exacerbation of symptoms one year after surgery.

Lymph node metastasis determined by histologic examination is an important prognostic indicator in gastric carcinoma. However, prognostic value of lymph node metastasis detected by computed tomography (CT) is unknown. The aim of this study was to evaluate clinical results and prognostic factors of patients with radiologically node-positive gastric carcinoma. The study included 78 patients with primary gastric carcinoma and lymph node metastasis confirmed by CT. The level of lymph node metastasis was simply graded as follows: level I included perigastric nodes; level II included intermediate nodes along the left gastric, common hepatic, and celiac arteries; and level III included distant nodes along the hepatoduodenal ligament, pancreas, spleen, and abdominal aorta. Sixty patients (79%) had stage IV tumors showing one or more of the following: level III lymph node metastasis in 37, pancreatic invasion in 27, peritoneal dissemination in 23, and liver metastasis in 19. Overall 1- and 5-year survival rates were 29% and 6%, respectively, and the 1-year survival rate was significantly influenced by the level of lymph node metastasis on CT (55% for level I, 27% for level II, 7% for level III, P < 0.01). In patients with gastrectomy, prognostic factors were tumor size (<10 cm versus >10 cm, P < 0.01), gross type (localized versus infiltrative, P < 0.01), histologic type (well differentiated versus poorly differentiated, P < 0.01), and curability of the disease (curative versus noncurative, P < 0.01). Our study indicates that prognosis of patients with radiologically node-positive gastric carcinoma is poor because of high frequency of extensive tumor spreads. Patients having only positive level I nodes on CT are candidates for curative gastrectomy, which may offer long-term survival.

The aim of this study was to elusidate the change in residual spleen volume after partial splenic embolization (PSE) in 43 cirrhotic patients with marked hypersplenism. Residual spleen volume was indicated as the rate (%) of residual spleen to initial spleen before PSE. Furthermore, the platelet count after PSE was observed in 23 patients followed up for 2 years. Residual spleen volume in patients with infarction rates of more than 80% (group A) had been maintained within 20 % even after 2 years, while they had obviously increased during the early stage after PSE in patients with infarction rates under 80% (group B), especially in patients with lower infarction rates (under 60%). Mean platelet count improved significantly in both groups after PSE (p < 0.001, respectively), but increased more in group A than in group B (p < 0.01). High fever and abdominal pain were observed in all cases of PSE. Other adverse effects such as pleural effusion and ascites that were frequent in group A were transient. These results suggest that PSE performed with a high infarction rate of the spleen provides effective, long-lasting results in the treatment of hypersplenism in cirrhosis.

We have evaluated the efficacy of partial splenic embolization (SE) in the treatment in 10 cirrhotic patients with marked hypersplenism. The mean infarction rate of the spleen was 84%. The change of spleen size, peripheral blood cell counts and liver function tests after SE were investigated during 3 years, and also 10 cirrhotic patients without SE were followed as control. The residual spleens after SE did not enlarged except 1 case with 65% infarction rate of the spleen. In these cases, the SE led not only to a sustained increase in both platelet and white blood cell counts but also to a significant improvement of hepatic function tests (hepaplastin test, total cholesterol and albumin) during observation period. On the other hand, these parameters tended to decrease in control patients without SE. This study suggests that SE performed with a high infarction rate of spleen is an useful therapy for hypersplenism in cirrhosis.

OBJECTIVES: The role of computed tomography (CT) for the staging of gastric carcinoma is controversial. The purpose of this study was to evaluate the utility of CT in assessing the perigastric spread of advanced gastric carcinoma. METHODS: The study included 56 patients who underwent dynamic CT and laparotomy for the treatment of node-positive gastric adenocarcinoma. Preoperative CT findings were compared with surgical findings, and diagnostic accuracy was estimated. RESULTS: Sensitivity, specificity, and accuracy of preoperative CT in determining the perigastric tumor spreads were 33, 97, and 73% in pancreatic invasion, 36, 97, and 70% in level III lymph node involvement, and 89, 98, and 96% in liver metastasis. Peritoneal dissemination was not detected in 15 of 56 patients (27%), and stage IV disease was not diagnosed correctly in 18 of 40 patients (45%). CONCLUSIONS: Radiologists and surgeons must remember that pancreatic invasion, extended lymph node metastasis, and peritoneal dissemination are sometimes overlooked in CT examination in patients with advanced gastric carcinoma.

A 62-year-old man having advanced gastric carcinoma with extended lymph node metastases was successfully treated by a palliative gastrectomy and 6 courses of sequential methotrexate/5-fluorouracil therapy. No side effects were observed, and all enlarged abdominal lymph nodes disappeared. The complete response has continued for 11 months after the initial treatment.

Five patients with hypersplenism associated with liver cirrhosis were treated by PSE and the changes of peripheral blood cells and liver function tests were observed. After PSE, all patients had a high fever and abdominal pain continued for a few weeks without severe complications. Peripheral blood cell counts improved soon after PSE and liver function tests (hepaplastin test and ICGR15) grew transiently worse, but they also improved within two months. During 4.5 to 10 months, the levels of albumin and total cholesterol of three patients increased, although the changes of bilirubin level and HPT were not shown. For other two patients, it was difficult to estimate the effect of PSE, because one patient was treated at the same time with lipiodol chemoembolization for HCC and another patient had a progress of nephrotic syndrome. On the other hand, ICG levels were stable after PSE but RI-uptake on liver scintigram increased in the liver. These results suggest that PSE may be able to improve not only hypersplenism but also liver function in the patients with compensated liver cirrhosis without severe complication.
