Background: Survival and cure rates for childhood cancers in Europe have greatly improved over the past 40 years and are mostly good, although not in all European countries. The EUROCARE-5 survival study estimates survival of children diagnosed with cancer between 2000 and 2007, assesses whether survival differences among European countries have changed, and investigates changes from 1999 to 2007. Methods: We analysed survival data for 157499 children (age 0-14 years) diagnosed between Jan 1, 1978 and Dec 31, 2007. They came from 74 population-based cancer registries in 29 countries. We calculated observed, country-weighted 1-year, 3-year, and 5-year survival for major cancers and all cancers combined. For comparison between countries, we used the corrected group prognosis method to provide survival probabilities adjusted for multiple confounders (sex, age, period of diagnosis, and, for all cancers combined without CNS cancers, casemix). Age-adjusted survival differences by area and calendar period were calculated with period analysis and were given for all cancers combined and the major cancers. Findings: We analysed 59579 cases. For all cancers combined for children diagnosed in 2000-07, 1-year survival was 90·6% (95% CI 90·2-90·9), 3-year survival was 81·0 % (95% CI 80·5-81·4), and 5-year survival was 77·9% (95% CI 77·4-78·3). For all cancers combined, 5-year survival rose from 76·1% (74·4-77·7) for 1999-2001, to 79·1% (77·3-80·7) for 2005-07 (hazard ratio 0·973, 95% CI 0·965-0·982, p<0·0001). The greatest improvements were in eastern Europe, where 5-year survival rose from 65·2% (95% CI 63·1-67·3) in 1999-2001, to 70·2% (67·9-72·3) in 2005-07. Europe-wide average yearly change in mortality (hazard ratio) was 0·939 (95% CI 0·919-0·960) for acute lymphoid leukaemia, 0·959 (0·933-0·986) for acute myeloid leukaemia, and 0·940 (0·897-0·984) for non-Hodgkin lymphoma. Mortality for all of Europe did not change significantly for Hodgkin's lymphoma, Burkitt's lymphoma, CNS tumours, neuroblastoma, Wilms' tumour, Ewing's sarcoma, osteosarcoma, and rhabdomyosarcoma. Disparities for 5-year survival persisted between countries and regions, ranging from 70% to 82% (for 2005-07). Interpretation: Several reasons might explain persisting inequalities. The lack of health-care resources is probably most important, especially in some eastern European countries with limited drug supply, lack of specialised centres with multidisciplinary teams, delayed diagnosis and treatment, poor management of treatment, and drug toxicity. In the short term, cross-border care and collaborative programmes could help to narrow the survival gaps in Europe.

Introduction Most countries in South-Eastern Europe (SEE) have lower incidence, but higher mortality rates of malignant melanoma (MM) of the skin compared to North-Western Europe (NWE). We explored trends in MM incidence and mortality in SEE countries by sex and age and compared them with the trends in NWE. Methods We obtained data on incident cases and deaths from MM (ICD-10 code C43) from 11 population-based cancer registries in Bosnia and Herzegovina, Bulgaria, Croatia, Cyprus, Czech Republic, Malta, Romania, Serbia, Slovakia, Slovenia and Turkey. We calculated age-specific rates for 25-49 ('young'), 50-69 ('middle aged') and 70+ years ('older') and estimated the average annual percent of change in incidence and mortality trends 2000-2010 according to age group and sex, using joinpoint regression analysis. Findings The incidence rates of MM across the region were uniformly increasing. Significant increases in mortality rates were observed in middle aged men in Serbia and Bulgaria, middle aged women in Slovenia, older men in the Czech Republic, Serbia and Turkey, and older women in Slovenia and Serbia. Interpretation While MM incidence rates were still increasing across SEE, mortality trends diverged and were less favourable than in NWE. Empowering cancer registration and improving the quality of incidence and mortality data will be essential for monitoring progress in MM control. In the context of prevention of melanoma, disparities in early detection appear to be widening the gap between SEE and NWE, while the provision of care to patients with advanced disease is likely to prove a challenge for regional healthcare budgets. © 2015 Elsevier Ltd.

Background Survival differences across Europe for patients with cancers of breast, uterus, cervix, ovary, vagina and vulva have been documented by previous EUROCARE studies. In the present EUROCARE-5 study we update survival estimates and investigate changes in country-specific and over time survival, discussing their relationship with incidence and mortality dynamics for cancers for which organised screening programs are ongoing. Methods We analysed cases archived in over 80 population-based cancer registries in 29 countries grouped into five European regions. We used the cohort approach to estimate 5-year relative survival (RS) for adult (≥15 years) women diagnosed 2000-2007, by age, country and region; and the period approach to estimate time trends (1999-2007) in RS for breast and cervical cancers. Results In 2000-2007, 5-year RS was 57% overall, 82% for women diagnosed with breast, 76% with corpus uteri, 62% with cervical, 38% with ovarian, 40% with vaginal and 62% with vulvar cancer. Survival was low for patients resident in Eastern Europe (34% ovary-74% breast) and Ireland and the United Kingdom [Ireland/UK] (31-79%) and high for those resident in Northern Europe (41-85%) except Denmark. Survival decreased with advancing age: markedly for women with ovarian (71% 15-44 years; 20% ≥75 years) and breast (86%; 72%) cancers. Survival for patients with breast and cervical cancers increased from 1999-2001 to 2005-2007, remarkably for those resident in countries with initially low survival. Conclusions Despite increases over time, survival for women's cancers remained poor in Eastern Europe, likely due to advanced stage at diagnosis and/or suboptimum access to adequate care. Low survival for women living in Ireland/UK and Denmark could indicate late detection, possibly related also to referral delay. Poor survival for ovarian cancer across the continent and over time suggests the need for a major research effort to improve prognosis for this common cancer. © 2015 Elsevier Ltd.All rights reserved.

Reporting of neoplasms in Bulgaria has been compulsory since a directive from the Ministry of Health in 1951. The quality of cancer registry data has been estimated rather infrequently in past years.We aimed to provide a comprehensive evaluation of the quality of the data at the Bulgarian National Cancer Registry (BNCR).Quantitative and semi-quantitative methods were applied for cancers diagnosed during the whole period 1993-2010, and also for cases diagnosed in 2006-2010. The methods used include historic data methods, mortality-to-incidence ratios (M:I), capture-recapture and death-certificate methods, proportions of morphologically verified cases (MV%), death-certificate-only cases (DCO%), and cases with missing information (primary site unknown, PSU%; stage unknown, SU%).The BNCR coding and classification systems follow international standards. The overall completeness was estimated at 92.6-94.7% for the period 2006-2010, with variations between cancer sites (86.7-98.5%). During the period 1993-2010, M:I decreased to 0.5 for males and 0.4 for females, MV increased to 87.4%, DCO and SU decreased to 4.8% and 18.8%, respectively, and PSU remained at the same level of about 4% for both sexes together. Sub-analysis revealed differences by site, sex and age groups. The comparison with other registries from the region showed similar incidence rates and directions of trends: M:I, MV% and DCO% that were not significantly different. The underreporting in 2008 and 2009 due to timely publication was estimated at an overall 0.8% and 0.5%, respectively.The present review showed that the BNCR yields internationally comparable data that are reasonably accurate, timely, and close to complete, especially in recent years. This is a prerequisite for the BNCR to expand its role to more areas of cancer control. © 2015 Elsevier Ltd. Source

Introduction: Cancer registration coverage and cancer control programmes in South Eastern (SE) Europe, embracing about six new EU member states, remain thin, despite a relatively high incidence and mortality burden from avoidable cancers, particularly in males. We assembled the most recent cancer registry data to estimate the burden of the 17 most common cancers in the region, from Slovenia to Cyprus and Malta. Methods: Data were made available for analysis from Bulgaria, Croatia, Cyprus, Malta, Romania (Cluj County), Serbia, Slovenia and Turkey (Antalya and Izmir provinces). We analysed incidence and mortality of the 17 most common cancers (counts and age-standardised rates, for the most recent year available and for the period 1999-2008). We used Joinpoint regression to quantify recent trends. Findings: For much of SE Europe, there were no marked declines in overall cancer mortality rates during 1999-2008. In men, lung cancer incidence and mortality rates were high compared to other European countries (age-standardised rates (ASRW) of incidence being 50-60/100,000 in most of the countries), and still increasing in Bulgaria, Serbia and Turkey. Prostate cancer incidence rapidly increased throughout the region by 3-12% annually, largely without any clear declines in mortality. Colorectal cancer incidence increased throughout the region, as did mortality especially in Croatia, Serbia and Bulgaria (average annual percentage change (AAPC) 1.5-2%). In women, breast cancer mortality significantly declined in Slovenia, Croatia and Malta (Average Annual Percentage of Change [AAPC] -2%, -1% and -5%, respectively), but not elsewhere. Cervical cancer incidence rates remained very high in Romania, Serbia and Bulgaria (ASRW > 20/100,000). Interpretation: Our data confirmed the North West to South East Europe gradient of increasing incidence and mortality rates of tobacco-related cancers, as well as increasing mortality rates of screen-detectable cancers. The lack of decline in overall cancer mortality also indicates suboptimal levels of cancer control in the region. © 2013 Elsevier Ltd. All rights reserved. Source
