ABSTRACT
INTRODUCTION: Europe contains 9% of the world population but has a 25% share of the global cancer burden. Up-to-date cancer statistics in Europe are key to cancer planning. Cancer incidence and mortality estimates for 25 major cancers are presented for the 40 countries in the four United Nations-defined areas of Europe and for Europe and the European Union (EU-28) for 2018. METHODS: Estimates of national incidence and mortality rates for 2018 were based on statistical models applied to the most recently published data, with predictions obtained from recent trends, where possible. The estimated rates in 2018 were applied to the 2018 population estimates to obtain the estimated numbers of new cancer cases and deaths in Europe in 2018. RESULTS: There were an estimated 3.91 million new cases of cancer (excluding non-melanoma skin cancer) and 1.93 million deaths from cancer in Europe in 2018. The most common cancer sites were cancers of the female breast (523,000 cases), followed by colorectal (500,000), lung (470,000) and prostate cancer (450,000). These four cancers represent half of the overall burden of cancer in Europe. The most common causes of death from cancer were cancers of the lung (388,000 deaths), colorectal (243,000), breast (138,000) and pancreatic cancer (128,000). In the EU-28, the estimated number of new cases of cancer was approximately 1.6 million in males and 1.4 million in females, with 790,000 men and 620,000 women dying from the disease in the same year. CONCLUSION: The present estimates of the cancer burden in Europe alongside a description of the profiles of common cancers at the national and regional level provide a basis for establishing priorities for cancer control actions across Europe. The estimates presented here are based on the recorded data from 145 population-based cancer registries in Europe. Their long established role in planning and evaluating national cancer plans on the continent should not be undervalued.

Background. We assessed differences in predicted breast cancer (BC) mortality rates, across Europe, by 2020, taking into account changes in the time trends of BC mortality rates during the period 2000-2010. Methods. BC mortality data, for 27 European Union (EU) countries, were extracted from the World Health Organization mortality database. First, we compared BC mortality data between time periods 2000-2004 and 2006-2010 through standardized mortality ratios (SMRs) and carrying out a graphical assessment of the age-specific rates. Second, making use of the base period 2006-2012, we predicted BC mortality rates by 2020. Finally, making use of the SMRs and the predicted data, we identified a clustering of countries, assessing differences in the time trends between the areas defined in this clustering. Results. The clustering approach identified two clusters of countries: the first cluster were countries where BC predicted mortality rates, in 2020, might slightly increase among women aged 69 and older compared with 2010 [Greece (SMR 1.01), Croatia (SMR 1.02), Latvia (SMR 1.15), Poland (SMR 1.14), Estonia (SMR 1.16), Bulgaria (SMR 1.13), Lithuania (SMR 1.03), Romania (SMR 1.13) and Slovakia (SMR 1.06)]. The second cluster was those countries where BC mortality rates level off or decrease in all age groups (remaining countries). However, BC mortality rates between these clusters might diminish and converge to similar figures by 2020. Conclusions. For the year 2020, our predictions have shown a converging pattern of BC mortality rates between European regions. Reducing disparities, in access to screening and treatment, could have a substantial effect in countries where a non-decreasing trend in age-specific BC mortality rates has been predicted (AU)

HSCT is associated with a high risk of late morbidity. The aim of this study was to evaluate the frequency, time frame, risk factors, and possible etiology of pulmonary dysfunction following allogeneic HSCT in childhood. We evaluated the pulmonary function of 51 HSCT patients (>6 yr), by including FVC and FEV1 values prior to (baseline) and annually up to five yr after HSCT. A Cox proportional hazards model was used to analyze the risk factors for a pulmonary event. Over half (59%) of the patients developed pulmonary dysfunction, mainly consisting of restrictive abnormalities. Acute GvHD (HR 4.31, 95% CI 1.47-12.63), chronic GvHD (HR 10.20, 95% CI 2.42-43.03), and an abnormal baseline pulmonary function (HR 4.82, 95% CI 1.02-22.84) were associated with post-transplant dysfunction. FEV1 (p < 0.001) and FVC (p < 0.001) declined significantly by 12 months after HSCT and both remained below the pre-HSCT level at up to four yr post-transplantation. HSCT in childhood is associated with early and persistent restrictive impairment of pulmonary function. Patients with extensive chronic GvHD are particularly vulnerable to severe pulmonary dysfunction. Scheduled pulmonary function testing is warranted as part of the follow-up of survivors of HSCT in childhood.

OBJECTIVE: To investigate the effect of cervical intraepithelial neoplasia (CIN) treatment on incidence of pregnancy and pregnancy outcome. DESIGN: Retrospective cohort study. SETTING: Helsinki University Central Hospital, Finland, the sole reference centre in the Helsinki-Uusimaa region for women referred for colposcopy. POPULATION: A cohort of 6179 women treated for CIN between 1974 and 2001, and a randomly selected, age- and municipality-matched, reference population of 30,436 women. METHODS: Based on nationwide registers, all women were followed-up for pregnancy outcomes until death, emigration, sterilization, or until the end of 2004. MAIN OUTCOME MEASURES: Incidence of any pregnancy, livebirths, miscarriages, extrauterine pregnancies, molar pregnancies, and terminations of pregnancies (TOPs) before and after CIN treatment, estimated by calculating hazard ratios (HRs) with stratified Cox regression and Poisson regression. RESULTS: After CIN treatment, both incidence of pregnancy (HR 1.20; 95% CI 1.15-1.26; P < 0.001) and incidence of livebirths (HR 1.12; 95% CI 1.06-1.18; P < 0.001) were higher among the treated women than among the reference population. Before treatment, only incidence of pregnancy had been elevated among those treated (HR 1.06; 95% CI 1.04-1.09; P < 0.001). The incidence of extrauterine pregnancies and of TOPs was significantly elevated among those treated both before and after CIN treatment. CONCLUSIONS: No clear evidence emerged of adverse effects resulting from the CIN treatment itself, because the women treated had more pregnancies and more children than their reference population. TOPs and extrauterine pregnancies were more common among the treated women already before the CIN treatment.

Despite the large number of studies on the impact of psychosocial factors on breast cancer progression, there is no certainty about the contributing factors or processes involved. We investigated the relative impacts of socioeconomic, psychological, and psychosocial factors on survival in breast cancer. A consecutive sample of 102 patients (participation 82%) under 72 years of age with locoregional breast cancer completed validated questionnaires on coping with cancer, emotional expression (anger), perceived available support, noncancer life stresses, and quality of life 3-4 months after diagnosis. Survival times were measured from the date of diagnosis to the date of relapse and further to the date of death or date of last follow-up. Cumulative Cox regression analyses were carried out. After controlling for biological prognostic factors, age, and baseline treatment, longer survival was predicted by a long education and a minimising-related coping, while shorter survival was predicted by emotional defensiveness (antiemotionality), behavioural-escape coping, and a high level of perceived support. A shorter event-free time was also predicted by unemployment and depressive symptoms. Cancer survival is affected by a complex combination of psychosocial factors, among which minimising predicts a favourable prognosis and anger nonexpression and escape behaviour an unfavourable prognosis. Higher socioeconomic status is associated with longer survival. High scores in well-being scales may reflect emotional nonexpression.

The paper compares three different methods for performing disease incidence prediction based on simple interpolation techniques. The first method assumes that the age-period specific numbers of observed cases follow a Poisson distribution and the other two methods assume a normal distribution for the incidence rates. The main emphasis of the paper is on assessing the reliability of the three methods. For this purpose, ex post predictions produced by each method are checked for different cancer sites using data from the Cancer Control Region of Turku in Finland. In addition, the behaviour of the estimators of predicted expected values and prediction intervals, crucial for investigation of the reliability of prediction, are assessed using a simulation study. The prediction method making use of the Poisson assumption appeared to be the most reliable of the three approaches. The simulation study found that the estimator of the length of the prediction interval produced by this method has the smallest coverage error and is the most precise.

A simple model is proposed for incidence prediction. The model is non-linear in parameters but linear in time, following models in environmental cancer epidemiology. Assuming a Poisson distribution for the age and period specific numbers of incident cases approximate confidence and prediction intervals are calculated. The major advantage of this model over current models is that age-specific predictions can be made with greater accuracy. The model also preserves in the period of prediction the age pattern of incidence rates existing in the data. It may be fitted with any package which includes an iteratively reweighted least squares algorithm, for example GLIM. Cancer incidence predictions for the Stockholm-Gotland Oncological Region in Sweden are presented as an example.

OBJECTIVE: To quantify the eventual extra loss of life incurred to cancer patients in Estonia compared with those in Sweden that was possibly attributable to differences in society. DESIGN: Population based survival of cancer patients in Estonia was compared with that of Estonian immigrants to Sweden and that of all cancer patients in Sweden. The cancer sites studied were female breast and ovary, male lung and prostate, and male and female stomach and colon. SETTING: Data on incident cases of cancer were obtained from the population based Swedish and Estonian cancer registries. PARTICIPANTS: Data from Estonian patients in Sweden, Estonian patients in Estonia, and patients from the total Swedish population were included in the study. MAIN RESULTS: Differences in survival among the three populations, controlling for follow-up time and age at diagnosis, were observed in breast, colon, lung, ovarian, and prostate cancers. The survival rates of Estonians living in Sweden and the total population of Sweden were better than that of the Estonians living in Estonia. For cancers of the breast and prostate, the excess mortality in the older age group (75 and above) was much greater in Estonia than in the other populations. CONCLUSIONS: Most differences in cancer survival between Estonian and Swedish populations studied could be attributed to a longer delay in diagnosis, and also to inferior treatment (including access to treatment) in Estonia compared with Sweden. Estonia's lag in socioeconomic development, particularly in its public health organisation and funding, is probably the main source of the differences observed.

The relationship of lung cancer risk to cigarette smoking, occupational exposure, air pollution at permanent residence and usual frequency of consumption of fruits and vegetables was analysed in a case control study in Cracow, Poland. The cases were 176 male lung cancer patients diagnosed in 1992-1994 with histological confirmation of the diagnosis, obtained from the population-based Cracow Cancer Registry, and 341 controls randomly selected from the general population. Classification of exposure to outside air pollution was based on measured level of total suspended particular matter and sulphur dioxide by particular districts of town (from 1973 to 1980). Except calculation of odds ratios for male lung cancer associated with exposures among all study subjects, the association between lung cancer risk and frequency of consumption of fruit and vegetables was examined among drinkers of vodka above average. Risk of lung cancer was increased significantly with increasing number of pack-years of smoking (OR = 18.7 for more than 40 pack-years). The significant inverse association of frequent usual consumption of boiled vegetables was present both among all subjects and among vodka drinkers (OR = 4.6 and 12.5, respectively, for a rare consumption). The risk of male lung cancer was negatively associated with the level of air pollution but positively with the percentage of occupationally exposed. Our study provides no evidence of a significant harmful effect of air pollution and found a strong inverse association between frequent fruit and vegetables consumption and lung cancer risk.

The relationship between cigarette smoking, vodka drinking and consumption of 44 food items typical of the Polish diet were analyzed in a case-control study performed in Cracow, Poland, among 76 cases of prostate cancer and 152 controls. Cigarette smoking and drinking of vodka were not significantly influencing the prostate cancer. The men who ate smoked or fried fish or liver at least once per week had almost half of the risk of prostate cancer of the men who ate those food rarely.

Based upon a group of 108 consecutive mammary carcinomas a comparative analysis of morphological parameters, DNA-ploidy and indicators of proliferation activity was made. A correlation between Bloom-Richardson scale, mitotic index, PCNA-labeling index and DNA-index was shown. The ploidy of mammary carcinomas was significantly related to the values of proliferative fraction, as well as to PCNA-labeling index. Among patients with axillary metastases the tumor size and the value of PCNA-labeling index were significantly higher than those in patients with negative lymph nodes.

BACKGROUND: Late menarche, early menopause, high parity, and early first birth decrease the risk of development of breast cancer. The influence of these factors on the survival of breast cancer patients has not been explained. METHODS: A group of 1885 patients with operable breast cancer was studied retrospectively. A univariate analysis was used to calculate 10-year overall survival (OS) and disease free survival (DFS) in relation to age, menopausal status, age at menarche and menopause, and number of pregnancies and deliveries. A multivariate analysis (Cox model) was performed in which classic prognostic factors (tumor size and grade, lymph node involvement) were included in addition to reproductive factors. RESULTS: Univariate analysis demonstrated better prognosis in patients who had never been pregnant compared with those who had (OS, 62% vs. 54%, respectively; P = 0.01; DFS, 53% vs. 44%, respectively; P = 0.005) and in nulliparous compared with parous patients (OS, 62% vs. 53%, respectively; P = 0.006; DFS, 52% vs. 44%, respectively; P = 0.004). Survival rates decreased with the number of pregnancies and deliveries. Patients with late menarche had worse survival then those whose first menstruation occurred before the age of 16 years (DFS, 47% vs. 41%, respectively; P = 0.04). By multivariate analysis, parity remained an independent prognostic indicator in addition to classic highly significant prognostic factors (nodal involvement, tumor grade and size). CONCLUSIONS: Results suggest that reproductive factors known to decrease the risk of breast cancer development have an adverse effect on prognosis.

Disease incidence predictions are useful for a number of administrative and scientific purposes. The simplest ones are made using trend extrapolation, on either an arithmetic or a logarithmic scale. This paper shows how approximate confidence prediction intervals can be calculated for such predictions, both for the total number of cases and for the age-adjusted incidence rates, by assuming Poisson distribution of the age and period specific numbers of incident cases. Generalizations for prediction models, for example, using power families and extra-Poisson variation, are also presented. Cancer incidence predictions for the Stockholm-Gotland Oncological Region in Sweden are used as an example.

The results of flow cytometric DNA-analysis on fresh and paraffin-embedded tissue were compared in four various groups of tumors. The best correlation of the results was observed in the group of non Hodgkin's lymphomas. Comparative analysis of the ploidy on fresh and paraffin embedded tissue demonstrated discordance in particular in mammary carcinoma and malignant melanoma groups. The values of proliferative fraction assessed on fresh and paraffin embedded tissues were interrelated.

A retrospective analysis of clinical and pathological prognostic factors was performed in 1,068 breast cancer patients treated with radical mastectomy alone in 1952-1980. Three endpoints were considered: 10-year survival, 10-year disease-free survival and 10-year loco-regional relapse-free survival. Both univariate and multivariate analyses confirmed the prognostic significance of tumour size, histological type and grade (Bloom classification) and involvement of axillary nodes for all three endpoints. Additionally, young age appeared to be a significant risk factor for loco-regional disease-free survival. Prognostic subgroups were defined by the use of 3 main indicators. In node negative patients with T1 tumours the prognosis seemed to be good regardless of histological grade (80-90% 10-year disease-free survival), in T2 tumours the survival was significantly dependent on histological type and grade. In node positive patients increasing number of involved nodes and higher histological grade had an independent adverse effect on all three endpoints. The study demonstrates that classical, commonly available prognostic factors clearly distinguish subgroups with different prognosis, which may be helpful when deciding on the use of adjuvant local and/or systemic therapies.

About 1% of the patients with oral cavity, larynx, and lung cancer get second primary malignant neoplasms every year. For laryngeal cancer the percentage exceeds 10. Second primary tumors in oral cavity, larynx, and lung cancer patients are also tobacco-related neoplasms. Smoking cessation by patients with oral cavity, larynx, and lung cancer may have significant influence on the prognosis. Vitamin A (retinol) and its analogues are promising for human cancer prevention.

A prospective study was conducted to determine the effectiveness of adjuvant hormonotherapy in endometrial cancer after surgery. Two hundred and five patients were randomly assigned to adjuvant progestagen treatment or were given no additional therapy. The follow-up was 5-years. We concluded that there was evidence of gain from adjuvant progestagen therapy in postoperative endometrial cancer. The group of patients who received progestagens had significantly longer survival than the control group without hormonotherapy (Logrank test; P < 0.001).
