rrhe marked resistance of the glandular stomach of animals to spontaneously occurring cancer is well known. A similar resistance to the experi mental production of cancer has been observed, since carcinogenic agents have been fed to mice and rats without producing cancer of the glandular stomach (6) . However, when threads saturated with methylcholanthrene were imbedded in the mucosa of the sto...
The frequency and clinicopathologic significance of the K-ras gene point mutation in stomach cancer remain to be defined. We investigated the frequency of K-ras codon 12 point mutations in stomach cancer using a polymerase chain reaction (PCR)-based method in 94 samples and 100 age and sex matched controls. The overall frequency of K-ras codon 12 point mutations in stomach cancer was 3.19% (3/9...
Background: Every year thousands of people die because of stomach cancer and brain tumors. N. sativa plant has thymoquinone and this compound may prevent cancer cell line growth in many types of cancer. The purpose of this study was to examine the possibility of inhibiting cell growth in human stomach gastric adenocarcinoma (AGS) and astrocytoma cell lines (AST) by N. sativa and N. arvensis ext...
We aimed to characterize the trends and projections of cancer mortalities in Yangpu, an industry restructuring district of Shanghai, China. With high-quality data from the death registration system, the authors analyzed the trends in cancer mortalities during 1974-2014 and their relationship with pollution control and socioeconomic improvements. Cancer burden was projected into 2029. During 197...
Among a total of 1259 patients with oesophageal cancer who underwent surgical resection, intramural metastasis (IMM) was verified in 93 patients (7.4%), of which IMM to the stomach (IMMS) constituted 13 patients (1.0%). In all 13 cases, the primary cancer was located in the middle or lower thoracic oesophagus and all had lymph nodes metastasis, while 12 of the 13 (92.3%) had lymphatic invasion....
The history of stomach cancer epidemiology is reviewed. The introduction of migrant population studies in the 1960 decade that described the critical role of exposures to this disease in early life was a key event. Companion pathology studies have indicated different epidemiological patterns for 2 histological entities, intestinal and diffuse type carcinomas, and confirmed an excess of intestin...
OBJECTIVES Chromium VI (hexavalent chromium, Cr(VI)) is an established cause of lung cancer, but its association with gastrointestinal cancer is less clear. The goal of this study was to examine whether the current human epidemiological research on occupationally inhaled Cr(VI) supports the hypothesis that Cr(VI) is associated with human stomach cancer. METHODS Following a thorough literature...
Gastric cancer in patients who have undergone bariatric surgery is rare. The authors present a case of stomach cancer in a patient 6 years after adjustable silicone gastric band placement. The tumour was located below the band, not in its direct vicinity. Aetiological and risk factors of stomach cancer incidence in obese patients are discussed in this case study.
In a search for aetiological processes which might explain the association of stomach cancer with poverty, we have related mortality from the disease in the local authority areas of England and Wales during 1968-78 to indices of living standards derived from the 1971, 1951 and 1931 censuses. We have also analysed recently released data from a national survey of overcrowding carried out in 1936....
