The 1970-72 cancer mortality of Polish migrants to England and Wales is compared with the cancer mortality prevailing in England and Wales and in Poland. Small numbers limit the analyses to the most frequent cancer sites only. The main findings are: (a) Compared with mortality rates in both their country of birth and of adoption, Polish migrants displayed intermediate values for cancers of the stomach, intestinal tract, and lung. For age-groups over 74 years, lung-cancer mortality among the migrants appears, however, to be higher than in both Poland and England and Wales. (b) A distinctly higher mortality among Polish migrants than either in Poland or England and Wales was apparent for lymphomas in both sexes, and for leukaemia and oesophageal cancer in males. (c) Female breast-cancer mortality among Polish migrants was much higher than in Poland, being close to the high mortality rates prevailing in England and Wales. The present findings are compared with the results of similar studies of Polish migrants to the United States and Australia and reasons for observed differences are advanced.

Twenty-five patients with unilateral partial absence of the pectoral major muscle were reviewed to determine the presence of fetal insult, associated anomalies, neoplasia, and prognosis. Fifteen had ipsilateral synbrachydactyly (the Poland Anomaly) which varied in severity from minimal findings to nearly complete absence of the hand. The pattern of abnormality was remarkably uniform with maximal involvement of the midhand and least involvement of the thumb and small finger. The etiology of this condition remains unknown although fetal insult is suggested in some cases. Although reports in the literature suggest a relationship with childhood leukemia, no malignancies were found in these children. None was found to have serious associated anomalies and all were judged to be of normal intelligence, suggesting a generally good prognosis.

We describe a 56-year-old female with absence of the right pectoralis muscles, aplasia of the right breast, and skeletal deformities of the right hand, typical of Poland's syndrome. Following complaints of lower abdominal pain, a CT examination revealed an 8-cm mass in the right anterior pelvic wall. Surgical resection of the mass revealed a high-grade, poorly differentiated leiomyosarcoma. Poland's syndrome is known to be associated with a high incidence of leukemia but this is the first description of its association with leiomyosarcoma. Although we cannot exclude the possibility of a chance association, it is reasonable to assume that, similar to other syndromes with multiple congenital anomalies, the association with an increased incidence of malignancy is an integral part of the underlying genetic abnormality.

A study was carried out to analyse trends in cancer mortality sex differentials. This study compared age-standardized sex ratio values for mortality from 18 cancers (or groups of cancers), and total cancer mortality over the period 1950-1989 in 24 European countries, for 4 age groups (all ages, 20-44 years, 45-64 years, and 65 years and over). For lung cancer and other tobacco-related neoplasms, appreciable rises in sex ratio values were observed until the late 1970s, particularly in Southern and Eastern Europe, before levelling off in recent years, particularly among the younger age groups. In the late 1980s, the range of variation in overall age-standardized sex ratios for lung cancer was between 2 and 3 in the United Kingdom and in Nordic countries, and around or over 10 in Southern Europe. In young adults, the decline in sex ratio values observed in Denmark and Sweden (unity), and in other Nordic countries and in the United Kingdom (around or below 2) reflects a levelling of lung cancer in young males and an increase in young females. This clearly indicates that young women are a priority target group for smoking control interventions in Europe. Appreciable cohort effects were also observed for stomach cancer: rises in sex ratio values were greater in, or restricted to, middle- and older age groups, whereas in the young there was some tendency towards a levelling in sex differentials. The overall sex ratio values for stomach cancer were around 2 in most areas of Europe in the late 1980s. For intestinal cancer, sex ratio values showed some tendency to rise, reaching a level of 1.3-1.7 in the late 1980s; steady rises were also registered in sex ratio values for melanoma (skin cancer), reaching 1.5-1.8 in the late 1980s in most countries. These upward trends which were minor or inconsistent at younger ages in several countries became progressively stronger with advancing age. Sex ratio values were below unity for cancers of the gallbladder and the thyroid. Sex ratio values tended to rise also for leukaemia (from 1.2-1.5 to 1.5-1.7), but showed no noticeable trend for lymphomas or myeloma. The overall sex ratio values for total cancer mortality in the 1950s were between 1.2 and 1.4 in most European countries. Thereafter, they rose appreciably in several countries, reaching 1.9 in Czechoslovakia, Italy and Poland, and 2.3 in France.(ABSTRACT TRUNCATED AT 400 WORDS)

Erythematous changes of the palms with associated oedema, blistering and desquamation were observed in two children during chemotherapy for acute lymphoblastic leukaemia, after methotrexate in doses of 1,000 mg/m2. These changes correspondent to those described in the literature as Burgdorf's reaction. In Poland it was never reported as yet.

Cancer risk in the Polish-born population of France has been compared to that in Poland and in native French subjects (born in France), using mortality data from the period 1979-1985. The Polish-born community in France is a long-established one--most migration occurred during the 1920s--so that for many cancer sites the cancer pattern is closer to that of French natives than that in Poland (eg oral cavity, oesophagus, large bowel, gall bladder, uterus, leukaemia). Polish migrants, however, retain their characteristically high rates of cancer of the stomach and lung (in men), and low rates of breast and prostate cancer. The Polish-born community has a characteristic pattern of residence (living mainly in the Nord and the Pas-de-Calais) and occupational status (a higher proportion of 'workers' than the French-born); these are important confounding factors which can mask the true differences in risk for several sites (larynx, oesophagus, large bowel) if no adjustment is made during analysis.

The rubber industry, acknowledged by the International Agency for Research on Cancer (IARC) to be a cancer risk technology is, because of difficulty in identifying causal factors, the subject of intensive epidemiological studies in many countries. In the presented study, cancer risk in the rubber industry was evaluated on the basis of long-term observation (1945-1985) of a cohort of 6978 male workers employed in a rubber goods factory, predominantly engaged in producing rubber footwear. The reference group was the general male population of Poland. Standardized mortality ratios (SMRs), calculated by means of the person-years method, were used in the evaluation of death risk. The observation of a whole cohort indicated an excess of cancer, in general (approx 12%), lung cancer (approx 40%) and gallbladder cancer (approx fourfold). In the subcohorts, distinguished according to peculiarities of individual production sections, cancer risk of the large intestine and larynx was significantly increased. The highest cancer risk was found in compounding, mixing, milling and vulcanizing sections. Hence, beta-naphthylamine, benzidine and solvents (benzene) were used in technological processes in the past, bladder cancer and leukemia were considered as most specific for the rubber industry. In the cohort observed, the risk of death from bladder cancer was significantly increased only in those who had been employed during the years 1945-1953, namely during the period when beta-naphthylamine was in use. No excess of deaths from leukemia was observed.

Poland's syndrome has been sporadically associated with haematological neoplasms, namely acute lymphoblastic and myeloblastic leukaemias and non-Hodgkin's lymphomas. The authors present the case of a child in whom this syndrome coexists with a Philadelphia negative, chronic granulocytic leukaemia, which has only required one course of treatment with busulphan in two and a half years of follow-up.

Recently a number of studies were carried on concerning malignant neoplasms, mainly leukemia, in workers exposed to electromagnetic fields. The studies focused upon power industry workers operating transmission--distribution lines, power stations, transformer stations and distribution substations which work at power--line frequencies. A review of selected literature was prepared concentrating on the methods describing conditions of exposure to e-m ELF fields as well as on the results of epidemiological studies. Also, the results of experiments carried on in Poland based on materials accessible only to a compact group of power industry experts were presented.

Using information data obtained from 958 patients with leukemia and the same number of healthy controls matched for sex, age and place of residence the relative risk of leukemia was calculated in relation to the character of the material from which the building was built where the patients and controls were living. The information on the type of the building materials was obtained by inquiry. Three types of buildings were isolated: buildings built from wood, bricks and concrete or prefabricated products. In the analysis the number of years during which the patients and controls were living in these buildings was considered. No statistically significant correlation was noted between the risk of leukaemia development and the character of the building material. No increase was noted in this probability in relation to the time of living in a building built from any of these building materials. Additional analysis demonstrated that in Poland no so called "leukemic houses" are found, that is houses where during 5 years three of more cases of leukemia occurred.
