ABSTRACT

AIM: To investigate mortality reduction from gastric cancer based on the results of endoscopic screening. METHODS: The study population consisted of participants of gastric cancer screening by endoscopy, regular radiography, and photofluorography at Niigata city in 2005. The observed numbers of cumulative deaths from gastric cancers and other cancers were accumulated by linkage with the Niigata Prefectural Cancer Registry. The standardized mortality ratio (SMR) of gastric cancer and other cancer deaths in each screening group was calculated by applying the mortality rate of the reference population. RESULTS: Based on the results calculated from the mortality rate of the population of Niigata city, the SMRs of gastric cancer death were 0.43 (95%CI: 0.30-0.57) for the endoscopic screening group, 0.68 (95%CI: 0.55-0.79) for the regular radiographic screening group, and 0.85 (95%CI: 0.71-0.94) for the photofluorography screening group. The mortality reduction from gastric cancer was higher in the endoscopic screening group than in the regular radiographic screening group despite the nearly equal mortality rates of all cancers except gastric cancer. CONCLUSION: The 57% mortality reduction from gastric cancer might indicate the effectiveness of endoscopic screening for gastric cancer. Further studies and prudent interpretation of results are needed.

ABSTRACT

Here we report a case of gastric cancer with diffuse abdominal wall invasion treated with weekly low-dose paclitaxel therapy. A 62-year-old male visited our hospital because of abdominal distention, prepubic tumor,and testicular hydrocele. Computed tomography revealed diffuse swelling of the abdominal wall and hydronephrosis of the right kidney. Upper gastrointestinal endoscopy demonstrated type 3' advanced gastric cancer. Pathological diagnosis of both gastric tumor and abdominal wall biopsy specimens was poorly-differentiated adenocarcinoma containing signet ring cell carcinoma. Low-dose paclitaxel (90 mg/body) was given once a week for 3 weeks. Abdominal wall swelling like cuirass disappeared after 2 courses of low-dose paclitaxel therapy. Nine repeated courses of this regimen have been given until now; the relapse of the abdominal wall invasion has not become apparent, and primary gastric lesion has been a stable disease. Diffuse abdominal wall invasion of gastric cancer like cuirass without ascites is a rare condition, and low-dose paclitaxel was very effective for this condition.
