Serum beta2-microglobulin levels have been measured in 210 cancer and control patients to assess the significance of this investigation in cancer patients. Subjects studied included patients with breast and gastrointestinal cancer, corresponding control patients in both categories, and healthy volunteers. The composition of these groups allowed an assessment of the relative importance of changes related to cancer, benign disease, age and sex. A significant rise in serum beta2-microglobulin levels with advancing age was demonstrated in the control subjects. Mean levels were also consistently higher in females than in males in each patient group. After statistical correction for these age and sex effects, mean values remained significantly higher in each of the various cancer groups than in their controls. Patients with more advanced breast cancer had higher levels than those with 'early' disease, as did patients with stomach cancer compared to those with colo-rectal cancer. One possible interpretation is that levels increase with increasing tumour bulk, and therefore the estimation of serum beta2-microglobulin may be useful as one of a battery of tests in the management of cancer patients.

A method for determining the incidence of malignancies of the stomach, colon, rectum, and lungs has been based on the frequency of the tumors in the autopsy material of the Institute of Pathology of the University of Heidelberg for the period 1900 to 1975. The main goal of this model is time independent selection of autopsy material indicated by an almost constant pattern for sex, average age at death, number of inhabitants, and number of autopsies. There is a relationship between incidence and autopsy frequency only when coding the diagnoses independently of their contributions to the cause of death. The results show a nearly constant incidence of stomach cancer, a steady incidence of colon and rectal cancer which, however, differs for men and women, and a large increase in the incidence of lung cancer.

Of 13 cancers that tend to occur at lower rates in aboriginal Americans or in the native lands of Japanese, Chinese, and Spanish-speaking persons than in United States whites, rates for all but one (laryngeal) have increased in migrants to the United States. In addition to leukemia, these 13 cancers include neoplasms that have been related, at least in part, to a diet high in animal fats or proteins (colon and rectum cancer); reproductive and endocrinologic factors and a diet high in animal fats or protein (prostate, ovary, corpus uteri, breast, and testis cancer); chemical carcinogens (lung, larynx, bladder, and pancreas cancer); and a common infectious agent that, like polio viruses, causes clinically overt disease with a frequency directly related to age of patient at initial infection (Hodgkin's disease). Of 9 cancers that occur at higher rates in aboriginal Americans or in one or more of the native lands of migrants than in United States whites, the rates of 5 tend to decrease in migrants. These include cancers that may be related to food preservation (stomach cancer); products of microorganisms that may contaminate foods (esophagus and liver cancer); and infectious agents (nasopharynx, cervix uteri, and liver cancer). In addition, rates of cancer of the thyroid are high in aboriginal Americans; those of the gallbladder are high in individuals of native American ancestry and in Japanese; incidence of salivary gland tumors is high in Alaskan natives and Colombians; and rates of kidney cancer are high in Alaskan natives. Five types of epidemiologic studies are described that should be conducted in the migrants and in their countries of origin and adoption to elucidate further the etiology of various neoplasms.

Results of cytological examination in 120 cases of colon and rectum cancer during the 11-year period ending in 1968 prior to the practical use of fibercolonscope were first studied. At that time, quite favorable results were obtained in cancer of the lower colon and the rectum, but the results were not so satisfactory in cancer of the right side of the colon. After 1969 when the fibercolonscope was introduced into the clinical practice, the range of cytological diagnosis under direct vision was at once expanded to the entire colon. Consequently, diagnosis by the cytological method in 140 cases of cancer of the colon and rectum experienced in 6-year period between 1969 and 1974 revealed favorable results. The results of the cytological diagnosis in cancer of the right sied of the colon, previously not always favorable, improved markedly after the introduction of the cytological method under direct vision through fibercolonscope. When early cancer of the colon and rectum is defined as in early gastric cancer, 40 lesions in 36 patients were detected during the past 19 years. The rate of positive result in cases of early cancer obtained by various diagnostic methods was 83% by the cytological method, 78% by biopsy and 91% by polypectomy. In cases in which both biopsy and cytological method were used, one or both frequently gave positive results. These results would indicate the possibility of correct diagnosis in many cases through the combined use of the cytological method and biopsy, without polypectomy.

The therapeutics on gastrointestinal cancer including only randomized clinical trials carried out in Western Europe and in the EORTC are reported. The studies on preoperative radiotherapy in resectable esophagus cancer and on chemotherapy associated to radiotherapy in nonresectable esophagus cancer has just been activated. The data of a trial on the treatment of gastric cancer have demonstrated the efficacy of long term 5-FU administered after postoperative irradiations. A trial on the immunostimulating effect of levamisole as adjuvant treatment of colon cancer is described, as well as the results of chemotherapy in advanced colon cancer. Finally, scribed, as well as the results of chemotherapy in advanced colon cancer. Finally, the preliminary results of two European trials studying the effect of preoperative radiotherapy and of a chemotherapy, used as a preoperative irradiation sensitizer in rectal cancer, are commented on.

Among 16 patients admitted into the Volynsk oncological dispensary with far-advanced tumors of the stomach and colon, the tumor perforation was recognized prior to surgery only in a half of the cases. Despite marked local proliferation and distant metastases there may be a pronounced pain syndrome. The absence of parallelism between the moment of intestinal content getting into the abdominal cavity and the protective reaction of the anterior abdominal wall musculature was characteristic of these patients. While the symptoms of peritoneal irritation in perforated gastric cancer can be recognized within the period up to 2 hours, the perforation of rectal cancer is frequently not accompanied with peritoneal signs. Among gastric cancer patients the perforation was diagnosed within 6 hours in six cases. The time of recognition of perforated cancer of the transverse colon and rectum was 15--16 hours.

Tests for circulating carcinoembryonic antigen, CEA, in plasma were performed in 29 patients with colonic and rectal cancer, 37 patients with stomach cancer, and in 100 blood donors. Using 5.0 ng per ml as cut off, 48 per cent of the patients with colonic and rectal cancer and 32 per cent of the patients with stomach cancer had elevated CEA-values. The CEA-values could be correlated to the classification of tumours according to Dukes, with significantly elevated values in groups Dukes C and D. The test could reveal 39 per cent of the cases with operable colonic and rectal cancer and 26 per cent of the operable cases of stomach cancer. Five patients with colonic and rectal cancer, and 0 patients with stomach cancer fulfilled the requirements for monitoring. After periods of observation of up to 14 months, definite connection between CEA-values and clinical course could be demonstrated in 1/26 patients submitted to macroscopically radical operation. In 2/7 patients with stomach cancer the CEA-values were entirely misleading. It is concluded that the CEA-test in its present form cannot be recommended for routine employment in patients with gastrointestinal cancer.

Mortality of maligant neoplasms of stomach (ICD 151; 84 529 deaths), colon (ICD 153; 13237 deaths), rectum (ICD 154; 13687 deaths), breast (ICD 174; 24400 deaths), and uterus (ICD 180--182; 25308 deaths) in the GDR in the years from 1960 to 1969 is described. There are regional differences of mortality which cannot be explained by demographic and diagnostic factors solely but suggest that there exist real differences of cancer risk. Mortality of stomach cancer is relatively low in the middle regions (Berlin, Frankfurt, Potsdam, Cottbus) and in the region of Erfurt and remakably high in the regions of Schwerin, Neubrandenburg, Gera, Leipzig and Karl-Max-Stadt. Mortality of colonic cancer is highest in Berlin, lowest in Schwerin, Neubrandenburg and Gera. Mortality of rectum cancer shows minor regional differences and another distribution than colonic ancer. Mortality of breast cancer is extremely high in Berlin and very low in Suhl. Mortality of cancer of the uterus reaches high levels in Neubrandenburg and is very low in the region of Karl-Marx-Stadt. In the period 1960--1969, mortality of stomach cancer has decreased whereas mortality of colonic cancer has increased. Mortality of rectum neoplasm remained constant. The time trend of mortality of breast cancer demonstrates regional differences and has increased somewhat in th GDR. Mortality of uterus cancer has slightly decreased. Regional differences and time trends of cancer mortality in the GDR suggest the influence of environmental factors.

11-Oxycorticosteroids levels were determined in 371 patients with breast, stomach and rectal cancer in the process of surgical treatment. More pronounced reaction of the adrenal cortex to surgical stress and/or time-delayed restoration of the hormone level within the next few days were found in older patients. Resistance to inhibition by dexamethasone in stomach cancer patients was accompanied by elevated cortisol levels during operation. It is concluded that age-related decrease in hypothalamo-pituitary complex sensitivity to inhibition by corticosteroids may be a cause of hypercortisolemia in the course of surgery.

A historical prospective cohort study of 6630 drivers from the Canton of Geneva was carried out to evaluate mortality and incidence of cancer in this occupation. The study population was all men (of all vocations) who held in 1949 a special licence for driving lorries, taxis, buses, or coaches and all new licence holders in the period 1949-61. Men born before 1900 and those with only an ordinary driving licence were excluded. According to the occupation registered on their licence, the 6630 drivers were distributed into three groups: (1) professional drivers (n = 1726), (2) non-professional drivers "more exposed" to exhaust gas and fumes (this group included occupations such as vehicle mechanic, policeman, road sweeper; n = 712), and (3) non-professional drivers "less exposed," composed of all other occupations (n = 4192). The cohort was followed up from 1949 to December 1986 and the trace of 197 men (3%) was lost. Compared with the general population of the Canton of Geneva, professional drivers experienced significant excess risks, taking into account 15 years of latency, for all causes of death (standardised mortality ratio (SMR) 115, 90% confidence interval (90% CI) 107-123) and for all malignant neoplasms (SMR 125, 90% CI 112-140; standardised incidence ratio (SIR) 128, 90% CI 115-142). Cause specific analysis showed significant excesses for lung cancer (SMR 150, 90% CI 123-181; SIR 161, 90% CI 129-198), oesophageal cancer (SMR 183, 90% CI 108-291), stomach cancer (SMR 179, 90% CI 117-263; SIR233, 90% CI 156-336), rectal cancer (SMR 258, 90% CIU 162-392; SIR 200, 90% CI 127-300), and cirrhosis of the liver (SMR 145, 90% CI 104-198). Risk of lung cancer increased significantly with time from first exposure. Among non-professional drivers no significant excess risk was found except for lung cancer mortality among the "less exposed" group (SMR 121, 90% CI 103-140), and for incidence of lung cancer among the "more exposed" group (SIR 161, 90% CI 111-227). The possible casual relation between exposure to engine exhaust emissions and the increased risk for lung cancer and for cancer of the gastrointestinal tract found among professional drivers is discussed.
