Tumor-specific immunity to
carcinoma of the colon
, pancreas and stomach was assayed by tube LAI. Cancers of the colon, pancreas and stomach, were shown to possess organ-type specific neoantigens. In 115 patients with
colon cancer
, 100%, 75%, 61% with Dukes' A, B and C cancer were LAI positive, respectively. Even a microfocus of in situ cancer in a colon adenoma was sufficient to stimulate measurable tumor-specific immunity in the host. In Dukes' D cancer, 25% of patients with widespread metastasis were positive, whereas 100% with solitary lesions were positive. Reactive leukocytes from patients with
colon cancer
did not react to extracts of normal bowel mucosa or villous adenoma from LAI-negative patients. Leukocytes from 19% (3 of 16) of patients with colon adenomas reacted to the extract of
colon cancer
but not normal colon mucosa. Moreover, the LAI-positive response of the patients with colon adenomas or
colon cancer
is directed to a
colon cancer
TSA which is linked to beta2-microglobulin. These studies suggest that some colon adenomas express TSA before morphological evidence of cancer. It is not known if the acquisition of a cell surface TSA is an irreversible step toward unrestrained growth and metastasis. In pancreatic cancer, 100% of patients with cancers less than 5 cm and without metastasis were LAI positive, whereas 29% were positive when the cancer was greater than 5 cm or had metastasized. In Patients with stomach cancer, 100% with Stage II and 46% with Stage III and IV cancer were LAI-positive. Leukocytes from patients with other GIT cancers and from patients with inflammatory bowel disease or
pancreatitis
did not react with extracts of colon, stomach or pancreatic cancer. Leukocytes from patients with metastatic cancer, usually did not react in the tube LAI assay because their surfaces were coated in vivo with TSA. LAI reactivity was present when CEA was not detectable and when CEA levels were elevated LAI activity was often absent. The present study suggests that the automated tube LAI shows sufficient promise to warrant studies to determine its efficacy for the diagnosis of GIT cancers.

Serum RNase (ribonuclease) of normal persons and of patients with
pancreatitis
, carcinoma of pancreas, or other neoplasms was determined with poly(C) as substrate. Strikingly abnormal elevations occur in the serum RNase of patients with pancreatic cancer. There is no elevation in the serum RNase level of patients with
pancreatitis
. Average serum RNase values of 52 normal persons, 10 patients with
pancreatitis
, 30 patients with pancreatic cancer, 28 patients with breast cancer, 11 patients with lung cancer, 20 patients with
colon cancer
, six patients with stomach cancer, and four patients with liver cancer, respectively, were 104, 120, 383, 131, 173, 197, 194, and 152 units/ml of serum. Ninety percent of the patients with pancreatic cancer were above the level of 250 units of serum and 90% of all patients with varied cancers were below this level. In the presence of severe renal insufficiency, marked elevation of serum RNase was also observed. Serum RNase, because of its unique specificity, pancreatic origin, and its abnormal elevation in sera of patients with pancreatic cancer, serves as a reliable biochemical marker of carcinoma of the pancreas in the presence of normal renal function.

The relationship between selected aspects of medical history and the risk of colorectal cancer was analysed using data from a case-control study of 673 cases of
colon cancer
, 405 of rectal cancer and 1501 controls in hospital for acute, non-neoplastic, non-digestive tract conditions, unrelated to known or suspected risk factor for large bowel cancer. Significantly elevated risks (RR) were observed for history of cholelithiasis (RR = 1.5 [95% confidence interval (CI) 1.1-2.1] for colon; 1.6 [1.2-6.4] for rectum) and diabetes (1.6 [1.1-2.3] for colon; 1.3 [0.8-2.0] for rectum), and a significant protection emerged for history of drug allergy (0.6 [0.4-0.9] for colon; 0.6 [0.5-1.0] for rectum). No significant association was found with thyroid disease, gastroduodenal ulcer, liver cirrhosis, hepatitis,
pancreatitis
, gastrectomy, appendicectomy, treatment with cimetidine/ranitidine, treatment with chenodesoxycholic acid or with blood transfusions. The associations with cholelithiasis, diabetes and drug allergy were not materially modified by allowance for major identified potential confounding factors, and were not restricted to the diseases diagnosed within 5 or 10 years before large bowel cancer diagnosis. Thus, the analysis of this large dataset offered further quantitative evidence suggesting a possible, however moderate, association between gallbladder disease and colorectal cancer risk, which may be related to enhanced or continuous secretion of secondary bile acids. The associations with diabetes and drug allergy were unexpected, and probably indirect, lacking previous epidemiological support or any obvious biological interpretation. Thus, they should be simply regarded as working hypotheses worthy of further consideration.

Basic evaluation of SPan-1 assay (SPan-1 RIA. BEAD) and clinical significance of serum SPan-1 levels for the diagnosis of pancreatic cancer were studied. This assay was reproducible, reliable and simple to perform. It required minimal samples (duplicate 50 microliters) and may be done within 4 hrs. Normal subjects (N = 1182) had serum SPan-1 antigen levels which ranged 0 to 42.8 units/ml with a mean of 7.5 units/ml and above 40 units/ml was considered to be positive. SPan-1 antigen levels in cultured medium of four out of five pancreatic cancer cell lines showed more than 1000 units/ml by this assay. While over 90% of pancreatic cancer patients had elevated levels of serum SPan-1 antigen, only 0-17% of patients with other malignant and non malignant gastrointestinal diseases such as
pancreatitis
(chronic or acute), gastric cancer or
colon cancer
had above normal levels. Furthermore, levels of serum SPan-1 antigen correlated well with treatment and recurrence of disease in patients with pancreatic and gastric cancer. These results suggest that determination of serum SPan-1 antigen levels by this assay kit is useful for the diagnosis and monitoring of pancreatic cancer.

A child with a malignant undifferentiated adrenal medullary tumor of neural crest origin, removed at six months of age, was treated with chemotherapy and is alive without evidence of cancer after seven years. He developed osteomas of the skull, a thyroglossal cyst and has had one episode of gastrointestinal bleeding. A three-generation history of multiple colonic polyposis and
colon cancer
, osteomas, recurrent
pancreatitis
, and Wilms' tumor was elicited. One of three females in this family, with direct lineage from polyposis afflicted fathers, exhibited Gardner's Syndrome and Wilms' tumor. The constellation of tumors afflicting this family may represent an underlying defect of excessive cell proliferation affecting mesenchymal and neuroblastic tissue. These may be extracolonic conditions associated with Gardner's Syndrome.

Latex photometric immunoassay for CA19-9 was clinically evaluated. Reference interval of the assay was determined as 37U/ml based on the data of 350 healthy donors. CA19-9 values were higher in females than in males (p < 0.01) and distribution of CA19-9 values varied significantly depending on the Lewis blood types of the subjects; namely, subjects with Lea+b- gave highest CA19-9 values followed by those with Lea-b+ and then those with Lea-b- (p < 0.001). In the patients with various malignant diseases, positive rates were high (> 60%) in the patients with pancreatic, hepatic, and
colon cancer
. Meanwhile, false positive rates were around 25-50% in the patients with
pancreatitis
, cholelithiasis, benign hepatic disorders and benign lung diseases. When cut-off value was set at 100U/ml, false positive rates decreased drastically, while true positive rates remained slightly decreased. These findings indicate that, in this latex assay, CA19-9 values of 100U/ml or higher should be regarded as high risk factor of malignancy and values in the range of > or = 37U/ml and < 100U/ml might be considered as warning signal of various benign and malignant diseases.

Colonic varices are a rare finding, with variable clinical features. The authors describe the first case of colonic varices secondary to acute recurrent
pancreatitis
, and associated with
colon cancer
. There are about 70 reports of colonic varices; none of them is related to acute recurrent
pancreatitis
, whereas 52 are related to portal hypertension, and 9 are on a familial basis. Association with
colon cancer
is reported in one case, and seems to be occasional.

Review of the sparse literature on the prognosis of asymptomatic and mildly symptomatic gallstones reveals a diversity of methods, definitions, and groups of patients studied, which makes it difficult to draw conclusions. It appears that serious symptoms and complications develop in about 1% to 2% of patients with asymptomatic gallstones annually, with fewer complications developing in later years than in years soon after gallstones are discovered. In patients with stones with mild symptoms, rates of the development of complications are perhaps a little higher, about 1% to 3% per year. In patients who are initially mildly symptomatic, cholecystectomy for severe symptoms probably is undertaken in 6% to 8% per year in the early years, decreasing with longer follow-up. Other than symptoms, no factors related to prognosis have been established. Acute cholecystitis is the most common severe complication of gallstones. Based on follow-up studies, obstructive jaundice, cholangitis,
pancreatitis
, and cancer of the gallbladder are infrequent complications. Risk of subsequent
colon cancer
should not ordinarily be a factor when cholecystectomy is considered. Analyses of cost-effectiveness have not demonstrated substantial differences in life expectancy between patients with asymptomatic gallstones who undergo immediate open cholecystectomy compared with watchful waiting.

We reviewed the trends and death rates of pancreatic cancer and
pancreatitis
in Japan over the past four decades. It is a disturbing fact that the death rate due to pancreatic cancer is rising, parallel to that of lung cancer and
colon cancer
and that it is affecting primarily the elderly 65 years and older in both sexes. The cause of this increase is partially attributable to improvements in the diagnosis, changes in life-style, and smoking. The death rate due to chronic and acute pancreatitis has remained constant during the past four decades.

We review here the oxygen insensitivity of the histochemical assay of glucose-6-phosphate dehydrogenase (G6PDH) activity to detect cancer cells. This inexpensive and rapid assay can be performed within half an hour. Discrimination between cancerous and noncancerous cells is based on a combination of elevated G6PDH activity, decreased superoxide dismutase (SOD) activity, and decreased lipid peroxidation in cancer cells. The test discriminates between adenomas and carcinomas of the colon with a certainty of >80% and has a high prognostic value for survival of
colon cancer
patients.
Pancreatitis
and pancreatic cancer are discriminated with a certainty of 100%. Therefore, the test can be applied by pathologists to provide additional information in difficult cases of diagnosis of cancer and for prognosis.
