Abstract
We used data supplied by population-based cancer registries, collected and quality controlled using a common protocol, to analyse survival from acute non-lymphocytic leukaemia (ANLL) and chronic myeloid leukaemia (CML) among children in 17 European countries. Variations in survival in relation to age, country, histologic subtype and period of diagnosis (1978--1992) were examined. These are rare malignancies and survival can be studied reliably only by examination of data from a very large population (in this case EUROCARE). 5 years after diagnosis, overall survival was 44% (95% CI 33--55) for CML and 37% (95% CI 32--43) for ANLL. For both types of leukaemia, survival was slightly better for girls and worse in children under 5 years of age. Consistent with clinical literature, the ANLL subtypes with poorer prognosis were monocytic, megakaryocytic and erythroleukaemia. For ANLL, 5-year survival was better in Finland, the UK, The Netherlands and Germany (> or =40%); for CML, 5-year survival was highest in Italy, although the 95% CI were wide. The risk of death from ANLL and CML fell by 7% per year and 5% per year, respectively, after adjustment for age, gender and country. Since these rare childhood malignancies were virtually untreatable until 1970, these are very welcome trends.

Abstract
The aim of this study was to provide a comparative description of geographical variations and time trends in the population-based survival of European children with acute lymphoblastic leukaemia (ALL). Data on 13344 newly diagnosed children (0--14 years) with ALL were included in the EUROCARE study and were collected were collected by 34 population-based cancer registries (four comprising only childhood malignancies), operating in 17 countries (four in Scandinavia, two in Southern Europe, three in Eastern Europe, six in Continental Europe and two in the UK). Age-specific crude survival rates were estimated for boys and girls according to country for the period 1985--1989 and in adjusted form to attain comparability. Overall pooled and weighted rates were estimated as European standards. Children dead at diagnosis or diagnosed only through a death certificate were excluded. Geographical variation was also estimated by calculating the relative death rate with respect to the pooled overall European rate. After adjustment for age, gender and country, a Cox regression analysis was used to estimate time trends in survival. Survival was compared with that in the USA, Japan, Canada and Australia. During 1985--1989, the 1-year survival rate varied from 99 to 79%, the 5-year survival rate from over 80 to 56% (with the exception of Estonia; 34%; 95% confidence interval (CI) 20--52) among the various countries; the European weighted means were 90 (95% CI 87--93) and 72% (95% CI 69--75), respectively. Survival was particularly favourable in (south) Sweden, Finland, Germany and The Netherlands and rather unfavourable in Estonia and (surprisingly) France, where only 4% of its population was covered by the participating registries. Compared with the period 1978--1981, the hazard ratio for the period 1986--1989 decreased to 0.59 (95% CI 0.54--0.64) and -- in a smaller set of registries -- to 0.49 (0.45--0.55) for 1990-1992, an annual decrease in this rate of approximately 3.5%. During 1985--1989, the 5-year survival rates for European children were largely similar to those found in the USA, Canada and Australia, but markedly better than those in Japan. Higher survival rates were found for countries with 'good' access to centrally organised diagnostic and treatment facilities which stimulated 'aggressive' treatments according to a protocol. However, a subdivision according to risk profiles, e.g. according to the initial white blood cell count at diagnosis, could not be made and this might have explained partially the geographical differences in survival, because a positive association appeared between incidence at age 1--4 years and 5-year survival in most countries.

Abstract
This paper describes the database of children with cancer in the EUROCARE study and the methodology used to analyse and report survival. This is the first systematic evaluation of survival after childhood cancer on a large scale in Europe: approximately 45,000 cases were included, diagnosed between 1978 and 1992 (34,814 cases diagnosed in 1978--1989 and an additional set of 9495 cases diagnosed in 1990--1992) and followed-up until 1995. Data were provided from 34 population-based registries (four specialised for childhood cancer registrations and one specialised registry for childhood leukaemia) in 17 countries of Europe (where there was national coverage in 10 countries). Quality of the data was fairly good, given the general differences among the countries and their health systems, thereby allowing for comparisons between them. Among cases diagnosed in 1978--1989, overall 2.0% were lost to follow-up, 91.8% were microscopically diagnosed and 93.4% of alive cases had at least 5 years of observation. Survival proportions (observed survival) were calculated for each of the countries involved, by age group (0, 1--4, 5--9, 10--14 years), gender, different time periods and selected diagnostic groups. Age-standardised cumulative survival rates and European averages (weighted and pooled) were also computed. Cox regression models were used to evaluate geographical and temporal differences. The EUROCARE database represents a unique source of information on survival of childhood cancer patients in Europe, intercountry differences and time trends in survival.

Abstract
The existence of the EUROCARE database now makes it possible to compare population-based survival for childhood melanoma in different European populations. The database contains verified information, including histological data, from cancer registries in 17 European countries, and as such it represents a particularly important source of survival information on a very rare cancer like childhood melanoma. The aim of the present paper was to describe survival in children with melanoma (MM), by sex, age and subsite, diagnosed during the period 1978--1989, using analysis of the data of the European pool of cases. Five year-survival for childhood MM diagnosed in 1978--1989 in Europe, is relatively good (80%; 95% confidence interval (CI) 47--95 for boys and 78%; 95% CI 58--91 for girls). Analysis by subsite, revealed the survival for MM on the head and neck, legs and arms was generally higher than survival for MM on other cutaneous sites (trunk, neck and scalp). For skin melanomas outcome for girls was better than boys, adjusting for age and sub-site. We suggest that the good survival observed in childhood MM seems to be related to early diagnosis.

Abstract
Other articles in this issue of the European Journal of Cancer have described population-based survival analyses of specific types of childhood cancer included in the EUROCARE database, diagnosed since 1979. The present paper summarises the relevant estimates and comments on intercountry differences, focusing on possible distortions in the intercountry comparisons based on data produced by the cancer registries. Potential biases include a lack of exhaustiveness of both case ascertainment and follow-up for living status and also a lack of consistency in the use of classification of the childhood cancer types. Nevertheless, despite such biases, consistent differences are observed between European countries in the probability of survival following the diagnosis of a paediatric cancer. In most cases, poor population-based survival rates are probably explained by inadequacies in the adoption and implementation of therapeutic protocols that have been proved to be effective. In some instances, the cause of unsatisfactory estimates was the inclusion of a sizeable proportion of children with cancer in clinical trials which were found to be ineffective. A regression analysis of incidence, mortality and survival rates during 1978-1989 over the whole EUROCARE database strongly indicates that the prognostic improvements over time are real and cannot be attributed to changes in diagnostic procedures.

Abstract
BACKGROUND It has been suggested that calcitriol (C) could improve anemia in chronic renal failure. However it remains debatable whether vitamin D has a specific effect on erythropoiesis, or it acts via suppression of hyperparathyroidism. METHODS We enrolled 29 patients with chronic renal failure, free from malignancies, iron deficiency or other chronic or hematological diseases. Aluminium accumulation was also excluded by DFO test. 22 were on hemodialysis and 7 on conservative management, creatinine clearance ranging 22-48 ml/min. Their mean age was 62+/-28 years and duration of renal disease was 98+/-51 months. No patient under-went rHu-Epo or Vitamin D treatment. 4 subjects were enrolled as controls. Samples of peripheral blood were drawn for the Burst Forming Unit-Erythroid (BFU-E) assay. After isolation of mononuclear cells by density gradient centrifugation with Fycoll-Hypaque, a 15-day incubation was set up with four different conditions: a) adding standard dose, 3 U/ml, of r-HuEpo (Dompè Biotec), standard colture; b) combined doses of r-HuEpo, 3 U/ml, and C (Abbott), 30 pg; c) standard dose, 3 U/ml, of r-HuEpo and high dose, 300 pg, of C; and lastly d) combined high doses of r-HuEpo, 30 U/ml, and C, 300 pg. RESULTS In the b colture (combined low doses) a higher BFU-E proliferation was found vs standard (a) colture (33.2+/-15.5 vs 17.1+/-9.2, p<0.02); interestingly, either in the c and d studies BFU-E showed an even higher proliferation (52.3+/-24 and 86.3+/-37.8 respectively, p<0.01 vs a). No difference was found when evaluating separately preterminal and hemodialysis patients. In control subjects only colture d showed an increased BFU-E proliferation. CONCLUSIONS C has a direct effect on erythroid precursors proliferation in vitro, acting in a sinergystic manner with rHuEpo. C may be useful as adjuvant therapy for renal anemia.

Abstract
PURPOSE Penetrating liver wounds are related to many causes and rank second after blunt abdominal and liver trauma. We will report the clinical and radiological findings of our personal series of patients with penetrating trauma, especially by firearms and stab and cut wounds. We will also try to define the diagnostic workup of these traumas, which is especially based on CT signs of liver damage and associated changes and which is of basic importance for following treatment, both surgical or conservative. MATERIAL AND METHODS In the last seven years we retrospectively reviewed 31 cases of penetrating liver trauma. The patients were 19 men and 12 women, ranging in age 18 to 73 (mean 42), with penetrating liver injuries from firearms (16 patients) and stab (9 cases) wounds; 6 patients had injuries from different causes. Abdominal CT was carried out in emergency with the CT Angiography (CTA) technique in all patients. In the patients with suspected chest and abdomen involvement CT was performed from the mid-chest for accurate assessment of diaphragm and lung bases and to exclude associated pleuropulmonary damage. RESULTS Penetrating liver wounds were caused by firearms in 70% of cases, by stabbing in 12% and, in the extant 18%, by other causes such as home accidents, road and work traumas, and liver biopsy. In our series, the liver was most frequently involved, especially by firearms wounds; in our 16 cases the most frequent injuries were hemorrhagic tears. We found bullets in the liver in 6 cases. In one case of home accident the patient wounded himself while slicing bread with a long knife, which cut into the anterior abdominal wall and tore the anterior liver capsule, as seen at CTA. DISCUSSION AND CONCLUSIONS Penetrating wounds to liver and abdomen are less frequent than those to the chest. In the past decade the use of CT has changed the diagnostic and therapeutic approach to such injuries completely, decreasing the resort to explorative laparotomy and hepatorrhaphy. Indeed, CT provides a clear picture of the extent and severity of damage, which permits to choose a conservative treatment in case of intraparenchymal hematomas and lacerocontusive foci without hemoperitoneum, which can be followed-up with physical and CT examinations. Moreover, Helical CT could provide the early diagnosis of active bleeding in the peritoneum and of focal bleeding in the liver, thus permitting prompt hepatorrhaphy or targeted hepatectomy. A diaphragm injury suspected at CT should always prompt the surgeon to intervention, especially when hemothorax, lung base pneumothorax, large liver hematoma or tear of the liver dome are associated. Finally, subdiaphragmatic free gas indicates gut perforation associated with liver damage, in which case surgery is necessary too.

Abstract
BACKGROUND Marked differences in population based survival across Europe were found for colorectal cancers diagnosed in 1985-1989. AIMS To understand the reasons for these differences in survival in a new analysis of colorectal cancers diagnosed between 1988 and 1991. SUBJECTS A total of 2720 patients with adenocarcinoma of the large bowel from 11 European cancer registries (CRs). METHODS We obtained information on stage at diagnosis, diagnostic determinants, and surgical treatment (not routinely collected by CRs) and analysed the data in relation to three year observed survival, calculating relative risks (RRs) of death and adjusting for age, sex, site, stage, and determinants of stage. RESULTS Three year observed survival rates ranged from 25% (Cracow) to 59% (Modena), and were low in the Thames area (UK) (38%). Survival rates between registries for "resected" patients varied less than those for all patients. When age, sex, and site were considered, RRs ranged from 0.7 (95% confidence intervals (CI) 0.6-0.9) (Modena) to 2.3 (95% CI 1.9-2.9) (Cracow). After further adjustment by stage, between registry RR variation was between 0.8 (95% CI 0.6-0.9) and 1.8 (95% CI 1.5-2.2). Inter-registry RR differences were slightly reduced when the determinants of stage (number of nodes examined and liver imaging) were included in the model. The reduction was marked for the UK registries. CONCLUSIONS The wide differences across Europe in colorectal cancer survival depend to a large extent on differences in stage at diagnosis. There are wide variations in diagnostic and surgical practices. There was a twofold range in the risk of death from colorectal cancer even after adjustment for surgery and disease stage.

Abstract
BACKGROUND Only recently have extensive population-based cancer survival data become available in Europe, providing an opportunity to compare survival in Europe and the United States. METHODS The authors considered 12 cancers: lung, breast, stomach, colon, rectum, melanoma, cervix uteri, corpus uteri, ovary, prostate, Hodgkin disease, and non-Hodgkin lymphoma. The authors analyzed 738,076 European and 282,398 U.S. patients, whose disease was diagnosed in 1985-1989, obtained from 41 EUROCARE cancer registries in 17 countries and 9 U.S. SEER registries. Relative survival was estimated to correct for competing causes of mortality. RESULTS Europeans had significantly lower survival rates than U.S. patients for most cancers. Differences in 5-year relative survival rates were higher for prostate (56% vs. 81%), skin melanoma (76% vs. 86%), colon (47% vs. 60%), rectum (43% vs. 57%), breast (73% vs. 82%), and corpus uteri (73% vs. 83%). Survival declined with increasing age at diagnosis for most cancers in both the U.S. and Europe but was more marked in Europe. CONCLUSIONS Survival for most major cancers was worse in Europe than the U.S. especially for older patients. Differences in data collection, analysis, and quality apparently had only marginal influences on survival rate differences. Further research is required to clarify the reasons for the survival rate differences.

Abstract
PURPOSE To report our personal experience with the clinical and radiological diagnostic approach to stab and cut wounds of the thoracic cage and its content, a type of injury whose diagnosis and treatment, as well as the surgical approach, vary case by case. CT of deep penetrating wounds permits correct assessment of severe changes such as pneumothorax, hemothorax and pneumomediastinum. MATERIAL AND METHODS In the last three years we examined 57 patients (48 men and 9 women; mean age 34 years, range 16-54): chest radiography was performed in 51 of them, with orthogonal projections in the standing and sitting positions. Chest CT was performed in emergency with i.v. contrast agent injection, with scans from the midneck to the diaphragm insertion to study border regions. Thoracostomy with pleural drainage was performed in 35 patients with pneumothorax and hemothorax while thoracotomy was performed in 8 patients, namely 4 with injury to the diaphragm, 2 to the heart, 1 with tear of the main bronchial artery and 1 of the aortic arch. RESULTS The most frequent symptoms we found were chest pain (100% of cases) and dyspnea (84%); laboratory data showed anemia and decreased hematocrit levels in 28 cases. Chest radiography was negative in 14 cases. The patients were then examined with CT to exclude radiographic underestimation of minimal pneumothorax, small lacerocontusive or hemorrhagic foci and hemothorax, which were observed in 4, 2 and one cases, respectively, and where radiography was actually negative for traumatic changes. Chest radiography was positive in 43 cases: the most frequent finding was pneumothorax, with 37 cases (86%)--8 of them associated with hemothorax and 5 with pneumomediastinum. Lacero-hemorrhagic foci of lung parenchyma were found in 5 cases and single pulmonary hematoma from punch crossing was seen in 1 case. DISCUSSION AND CONCLUSIONS CT was an accurate tool and had higher sensitivity than chest radiography in detecting and detailing pneumothorax, pneumomediastinum and lacero-hemorrhagic foci, as well as in quantifying hemothorax. Chest radiography had 12% false negatives and therefore we decided to perform CT in all the patients with penetrating wounds to prevent radiographic underestimation. Given the low rate of false negatives (7/57 cases) CT might appear superfluous but since in 2 of these 7 cases we had massive pneumothorax and pneumomediastinum associated with neck emphysema we suggest its use to prevent complications, clinical failures and medicolegal problems. CT permits correct assessment of penetrating stab and cut wounds of the chest and efficient and targeted treatment, which can be conservative, with thoracostomy with pleural drainage, or surgical.

Abstract
The authors report a case of mesothelial cyst of the diaphragm in a boy 11 years old who was examined for pain in the right hypochondrium with exacerbation during respiratory movements. Ultrasonography and CT suggested the diagnosis. However the final diagnosis of mesothelial cyst of the diaphragm was possible only after laparotomy and histological examination. The topographical, clinical, radiological, therapeutic and histological aspects of primary cysts of the diaphragm are presented and a survey of the literature is made.

Abstract
OBJECTIVES To analyze cervical cancer survival trends in 10 European countries using models that estimate the proportion of cured patients (having the same life expectancy as the general population) and the survival of fatal cases (who die from cervical cancer). METHODS We considered 40,906 cases diagnosed over 12 years (1978-89) collected from cancer registries participating in EUROCARE. RESULTS From 1978 to 1989, 5-year relative survival in Europe improved (60%-->63%). The proportion of cured patients increased slightly but significantly (53%-->55%, p = 0.05). For countries with poorer survival at the end of the 1970s the proportion of cured patients increased faster than average, particularly evident in England (49%-->56%) and Scotland (44%-->53%). By contrast, in Finland, Sweden and Germany with organized screening, 5-year survival and cure rate did not improve, but incidence declined to very low levels. CONCLUSIONS Cervical screening can explain the trends in cervical cancer survival: this identifies premalignant lesions, reduces incidence and selectively prevents less aggressive cancers. The decreased proportion of the latter means that survival does not improve in countries with low incidence of cervical cancer. The increased proportion of cured patients with time shows that survival improvement was not due simply to earlier diagnosis with no patient advantage.

Abstract
PURPOSE We investigated to what extent the diagnostic findings of chest radiography can improve prognosis and treatment in surgical breast cancer patients. We also reviewed the literature and our personal findings to choose the optimal follow-up frequency to meet therapeutical and management needs, including radiation protection. MATERIAL AND METHODS We retrospectively reviewed 1556 chest radiographs of 195 surgical patients with M0 breast cancer performed January 1990 to December 1996. Patient's history and clinical data were accurately reviewed to investigate the relation between protocol type and results. The maximalist or intensive protocol featured 3 chest radiographs a year, even in the absence of any specific signs; the results were reviewed in terms of early diagnosis and prolongation of life. RESULTS Only 13% of the examinations had been performed following a specific clinical indication, while 87% had been performed for a generic referral. Recurrences were found in 0.6% only of the latter examinations, which means that radiography provided no diagnostic improvement or important change in treatment in as much as 99.4% of cases. In 1997 radiographic follow-up was made triannual instead of biannual as it used to be. DISCUSSION AND CONCLUSIONS In the absence of specific clinical indications, chest radiography can be performed in the two projections once a year. More aggressive protocols requiring more frequent examinations are not justified, as the patient's life expectancy is not increased. Yearly examinations permit to meet economic and management needs, with a better use of time, staff and materials. Moreover, the clinical-diagnostic yield is not affected by the skipping of unselected examinations. Finally, another pro is the technical thoroughness of the examination with orthogonal projections and the possibility to use ionizing radiations, which improves the management of clinical risks. Maximum radiologist-oncologist cooperation in clinical practice can improve both diagnostic efficiency and treatment efficacy, by reducing the population dose and rationalizing the use of human, instrumental, structural and financial resources.

Abstract
This study concerns the survival of European patients diagnosed between 1978 and 1989 with colorectal cancer. Variations in survival in relation to age, country and period of diagnosis were examined. Data from the EUROCARE study were supplied by population-based cancer registries in 17 countries to a common protocol. Five years after diagnosis, relative survival rates were 47 and 43% for cancers of the colon and rectum, respectively. Survival decreased with increasing age: the relative risk of dying for the oldest patients (75+) was 1.39 for rectum and 1.54 for colon compared with the youngest patients (15-44 years). In 1985-1989 survival from colorectal cancer differed significantly between different European countries: the Nordic countries (Denmark excluded), The Netherlands, Switzerland, France and Austria were characterised by high survival, whilst Eastern European countries, the U.K. and Denmark were characterised by low survival. There was a general improvement in survival over the period 1978-1989: from 40 to 48% for colon cancer and 38 to 46% for rectal cancer. For neither cancer site did between-country survival differences narrow over the study period. Intercountry and time differences in survival differences are probably related to stage at diagnosis and postoperative mortality.

Abstract
INTRODUCTION The origin of Peyronie's disease remains obscure although the first report of this condition dates back to 1743. The disease prevalence in 388.6 in 100,000 population and little physiopathologic information is available. Repeated microtrauma to the tunica albuginea appears to favor the onset of inflammatory phenomena which result in fibrosis and calcification. The disease activity produces a microvascularization around the fibrocalcific plaques. We studied the evolution of the inflammatory process in Peyronie's disease relative to clinical symptoms, in order to optimize treatment follow-up. MATERIAL AND METHODS We examined 20 patients with Peyronie's disease aged 34 to 56 years using a GE Sonora Logic 500 MD US scanner with linear probes of 7.5 and 13 MHz. The microvascularization around the plaques was studied with color and power Doppler investigations before contrast agent administration and with combined color and power Doppler after contrast agent administration. We injected Levovist (300 mg/mL) and 10 micrograms prostglandin E1 (PGE1). Examinations were repeated after 2-4 months in the patients with evidence of microvascularization around the plaques. RESULTS US demonstrated fibrocalcific plaques in all the patients. The microvascularization around the plaques was seen with color Doppler in 3 cases (15%), with power Doppler in 5 cases (25%) and with contrast-enhanced color and power Doppler in 7 cases (35%). At 2-4 months' follow-up, we observed slight plaque enlargement and worsened symptoms in 5 of 7 patients (71%) with evidence of some microvascularization around the plaque. CONCLUSIONS The plaque presence allows to define the condition and the microvascularization provides information on its evolution. The disease activity can be distinguished into 3 stages which can be related to the painful symptoms. US exhibits a better cost/benefit ratio than contrast-enhanced MRI.

Abstract
The study describes the prognosis of head and neck cancer in Europe on the basis of information available to population-based cancer registries collaborating in the EUROCARE II project. Variation in survival in relation to country and the anatomical site/sub-site of origin of the tumours was examined. Survival analysis was carried out on 35,004 head and neck cancer cases (ICD 141, 143-148 and 161) diagnosed between 1985 and 1989 in 17 European countries. Prognosis varied considerably according to anatomical site: the best 5-year survival rates were seen for cancer of the larynx (63% in men) and the worst for cancer of the hypopharynx (22% in men). Five-year relative survival of male patients with cancer of the tongue, mouth and pharynx (ICD 141, 143-148) was 34% and ranged from over 45% in Iceland, Sweden, The Netherlands and Austria to less than 25% in Eastern European countries. Survival for larynx cancer ranged from over 70% in Iceland, Sweden, The Netherlands and Germany to less than 50% in Slovakia, Poland and Estonia. Apparently, France had the lowest survival (relative risk (RR) of dying versus Finland = 1.29) in Western Europe; after adjustment for ICD 3-digit anatomical sites the difference disappeared (RR = 1.04). Eastern European countries remained at the bottom of the survival range (RR > 1.4). The analyses adjusting by sub-site (ICD fourth digit) were confined to registries for which the proportion of unspecified sub-sites was less than 20%. Geographical differences in survival between Western European countries were largely due to a difference in case mix of anatomical sub-sites. However, after correcting for different sub-site distribution, differences persisted between Eastern and Western European countries. This is likely to be due to late diagnosis and to late referral or poor access of patients to adequately equipped treatment centres.

Abstract
The EUROCARE study is a European Union project to collect survival data from population-based cancer registries and analyse them according to standardised procedures. We investigated and compared oesophageal and gastric cancer survival in 17 countries between 1985 and 1989. Time trends in survival over the 1978-1989 period were also investigated in 13 countries. The overall European 1-year relative survival rates were 33% for oesophageal cancer and 40% for gastric cancer. The corresponding 5-year relative survival rates were 10 and 21%, respectively. Important intercountry survival differences exist within Europe for oesophageal and gastric cancer. Taking the European average as the reference, the relative risk (RR) of death at 5 years was at least 30% higher in Denmark, Poland, Estonia and Slovenia for oesophageal cancer and in Denmark, England, Scotland and Poland for gastric cancer. In the other countries survival figures were close to the European average. Gender had little influence on survival, whilst age at diagnosis was inversely related to prognosis. There was a slight improvement between 1978 and 1989 in 5-year overall relative survival rates for both oesophageal cancer (RR = 0.80, 95% confidence interval (CI) 0.72-0.90) and gastric cancer (RR = 0.88, 95% CI 0.82-0.94). Differences in quality of care and stage at diagnosis can explain in part the differences in survival found in the EUROCARE countries. Significant improvement in prognosis has still to be achieved.
