Tumour-specific immunity to pancreatic tumour antigens, assayed by an automated tube leucocyte-adherence inhibition assay (L.A.I.), was detected in 3 of 3 patients with localised pancreatic cancer and 3 of 8 patients with more extensive pancreatic cancer. Leucocytes from pancreatic cancer patients with L.A.I. reactivity did not react to antigens of stomach, colon, or lung tumours; leucocytes from patients with stomach, colon, or lung cancer of inflammatory disease of the pancreas and bowel did not show L.A.I. reactivity to pancreatic tumour antigens.

Charts of 437 patients having plasma carcinoembryonic antigen determinations during the period January 1, 1976 through April 30, 1976 were reviewed to determine whether CEA results led to clinical decisions altering management patterns. Data analysis disclosed that CEA test results did not result in any change in management in 167 patients with non-neoplastic disease. Most had single determinations. In 270 patients with neoplastic disease, CEA results led to changes in management in one patient with lung cancer and two patients with colon cancer, which may have altered prognosis. In a fourth patient, CEA results led to discovery of unresectable pancreatic cancer at laparotomy. Cost benefit analysis indicated a CEA test cost of $5,047.50 per patient benefitted in 299 patients eligible for analysis. We conclude that maximal benefit to the patient results from serial CEA test use in follow-up of colon cancer patients after curative therapy.

Mortality in workers at a northwestern United States prebake-type aluminum reduction plant was examined in a historical prospective (cohort) study. Although the standardized mortality ratio (SMR) for all causes of death was low (86), lung cancer (SMR 117), pancreatic cancer (SMR 180), lymphatic and hematopoietic cancers (SMR 184), fatal benign tumors of the brain (SMR 391), and pulmonary emphysema (SMR 204) showed excess deaths. Analysis of mortality by job-exposure category, duration of employment and latency suggests that some of the lymphatic and hematopoietic cancers (especially malignant lymphoma), lung cancers and pulmonary emphysema may be of occupational origin in this worker population.

Amylase is composed by two isoenzymes groups: pancreatic or salivary type. This last part can be increased in many diseases. A case of lung cancer with elevated amylase activity in blood, urine and pleural fluid is reported in a 74-year-old man. This increase was due to salivary type isoamylases with an unusual component which disappeared by neuraminidase treatment. The significance and the origin of this hyperamylasemia with non pancreatic cancer are discussed.

Hyperamylasemia and hyperamylasuria were found in two patients with carcinoma of the pancreas and in two other patients with carcinoma of the lung. Detailed isoamylase analyses were conducted on the serum amylase of three and the urine amylase of all four of these patients, using a modified chromatographic procedure. The studies demonstrated the existence, in one of the lung cancer patients and in one of the patients with pancreatic cancer, of an unusual component of amylase given the designation "Y." This component had also been noted in some human milk samples. In one of the lung cancer patients, an isoamylase was found in the serum and urine after radiation treatment that was close to but not identical to the Y isoamylase in chromatographic position. Although a relationship of isoamylase component Y to generating tissue is suggested by these findings, such a relationship of isoamylase component Y to generating tissue is suggested by these findings, such a relationship remains to be proven.

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.

In a multicentre study patients with liver metastases stratified to the histology of the primary tumour were investigated. A total of 102 patients with colorectal adenocarcinoma, non-small-cell lung cancer, pancreatic cancer, primary liver carcinoma and malignant melanoma were treated with the thioether lipid ilmofosine. The drug was administered orally as a tablet at a dosage of 150-300 mg/day (75 mg/tablet). The tolerability of ilmofosine was poor. There was a dose-limiting gastrointestinal toxicity with nausea, vomiting and loss of appetite (WHO grade II-IV) in 67% of patients. During the period of therapy (1-29 weeks, 8.5 weeks mean) no complete remission and no partial response were observed. We thus conclude that treatment with oral ilmofosine is not effective in patients with liver metastases due to various malignancies.

Gemcitabine (dFdC) and DMDC are new antimetabolites with good antitumor activities against various tumors which include human leukemic cell lines and a number of rodent and human solid tumors and human tumor. They are structurally related to cytarabine (Ara-C) which is known as one of the most effective drugs against adult acute leukemia, but many solid tumors are insensitive not been found to the drug. Gemcitabine acts as an inhibitor of ribonucleoside diphosphate reductase and inhibits DNA synthesis. Biochemically Gemcitabine is rapidly phosphorylated to dFdCTP which has a comparatively longer half-life than that of Ara-C, showing a therapeutic activity against tumors. In the phase I trials, the reported maximum-tolerated doses were 790 mg/m2 to 1370 mg/m2 at the schedule of 30 minutes i.v. infusion once a week for three weeks but higher dose levels (2,500 mg/m2 to 4,800 mg/m2) were reported in the schedule of prolongation of the infusion time. Reported toxicities were myelosuppression, fatigability, fever, appetite loss and skin rash. Toxicities were seemed to be mild. In USA, Europe and South Africa, phase II trials of Gemcitabine at the schedule of 30 minutes infusion once a week for three weeks followed by one week rest were performed against solid tumors (breast cancer, ovarian cancer, renal cancer, colorectal cancer, pancreas cancer, head and neck cancer, and lung cancer) and showed good responses to those tumors. DMDC was developed in Japan, and a phase I trial is currently on-going.

Topoisomerase I represents a unique new target that can be exploited for development of new antineoplastic agents. There are now two new topoisomerase I inhibitors that are in early clinical trials that have generated a tremendous amount of interest. Topotecan (SKF 104864-A) is a topoisomerase I inhibitor that has been explored in phase I trials using a variety of dosages and schedules. The dose-limiting toxicity of the agent is neutropenia. Other toxicities include alopecia, very mild nausea and vomiting, anemia, and occasional fever. Responses have already been noted in patients with advanced, refractory ovarian cancer and non--small-cell lung cancer. The drug is currently undergoing intense phase II testing. Irinotecan (CPT-11) is also a topoisomerase I inhibitor, which has already undergone extensive phase I and early phase II clinical testing in both Japan and the United States. Dose-limiting toxicities of the agent have included neutropenia and diarrhea. Responses have been noted in patients with refractory colorectal cancer, non--small-cell lung cancer, lymphoma, ovarian cancer, head and neck cancer, pancreatic cancer, and breast cancer. There is no doubt both of these agents will be important additions to our chemotherapy armamentarium.

Mutational activation of ras oncogenes is frequently encountered in human tumors. For unexplained reasons, K-ras mutations are predominantly found in pancreatic cancer, colorectal cancer and adeno-carcinoma of the lung, N-ras is predominantly found in a subset of acute leukemias and in myelodysplastic syndromes, while H-ras mutations are rare. In most tumors, ras mutations are not clearly associated with specific clinical or biological features, but in lung cancer, childhood lymphoblastic leukemia and possibly in myelodysplastic syndromes ras mutations may predict a poor prognosis. Accumulating evidence suggests that exposure to chemical carcinogens is responsible for many ras mutations in humans.
