Summary Background Data from EUROCARE have consistently shown lower survival for adolescents and young adults (AYAs; aged 15–24 years) than for children (0–14 years) for most cancers that affect both ...groups, and modest survival improvements up to 2000–02. AYAs have longer survival than that of adults for most cancers. We used the latest definition of AYAs (aged 15–39 years) and provided estimates of 5-year relative survival for European AYAs with cancer diagnosed in 2000–07, compared with children and adults (40–69 years) with cancer, and assessed survival improvements over time. Methods We analysed data from population-based cancer registries of 27 European countries participating in EUROCARE-5. We used the so-called complete method to estimate 5-year, population-weighted relative survival for 19 cancers affecting AYAs and children, and for 27 cancers affecting AYAs and adults. We assessed relative-survival differences between children versus AYAs, and between AYAs versus adults, using the Z test. We used the period approach to estimate 5-year relative survival over time for children and AYAs, and used a generalised linear model to model survival time trends (1999–2007) and to assess the significance of changes over time. Findings We analysed 56 505 cancer diagnoses in children, 312 483 in AYAs, and 3 567 383 in adults. For all cancers combined, survival improved over time for AYAs (from 79% 95% CI 78·1–80·5 in 1999–2002 to 82% 81·1–83·3 in 2005–07; p<0·0001) and children (from 76% 74·7–77·1 to 79% 77·2–79·4; p<0·0001). Survival improved significantly in children and AYAs for acute lymphoid leukaemia (p<0·0001) and non-Hodgkin lymphoma (p<0·0001 in AYAs and p=0·023 in children). Survival improved significantly in AYAs only for CNS tumours (p=0·0046), astrocytomas (p=0·040), and malignant melanomas (p<0·0001). Survival remained significantly worse in AYAs than in children for eight important cancers: acute lymphoid leukaemias, acute myeloid leukaemias, Hodgkin's lymphomas, non-Hodgkin lymphomas, astrocytomas, Ewing's sarcomas, and rhabdomyosarcomas (p<0·0001 in all cases), and osteosarcomas (p=0·011). Interpretation Notwithstanding the encouraging results for some cancers, and overall, we showed poorer survival in AYAs than in children for the eight important cancers. Recent European initiatives to improve outcomes in AYAs might reduce the survival gap between children and AYAs, but this reduction can only be verified by future population-based studies.

Testicular cancer is one of the most treatable cancers, with a 10-year survival of more than 95%. Many patients will be long-term survivors and this disease strikes men in an important phase of their ...lives, therefore the quality of life (QoL) among these patients is an area of particular interest. We aimed to study whether QoL in testicular cancer survivors depends on the time since cancer diagnosis. Data were collected from the EPSAM (Esposizioni postnatali e salute maschile) study, a case-control study on patients with testicular cancer, diagnosed between 1997 and 2008 in the province of Turin, Northern Italy, and interviewed between 2008 and 2010 (response rate among cases 57%). Patients were contacted through their oncologist at the San Giovanni Batista Hospital in Turin or through their general practitioner (GP) in the rest of the Province of Turin. QoL was assessed cross-sectionally using the short form 12 (SF-12) questionnaire, a generic short-form health survey that produces two summary scores, PCS (physical component score) and MCS (mental component score), to evaluate physical and mental health, respectively. Out of 234 study patients, 125 cases were seminomas and 109 cases were nonseminomas. The mean age at diagnosis was 34.5 years. After adjusting for age, time since diagnosis was not associated with PCS and MCS scores. Among nonseminomas, the median PCS slightly increased (adjusted OR (odds ratio) for 5+ vs < 2 years since cancer diagnosis: 1.78 (1.17-2.73), p = 0.008) and MCS slightly decreased (adjusted OR per 1-year increase since cancer diagnosis: 0.92, 95% CI: 0.82-1.05, p = 0.23) with time. Similar findings of no association between time since diagnosis and PCS and MCS were found when the analyses were restricted to the subgroup of cancer patients contacted through their oncologist, whose response proportion was 82%. In a study of testicular cancer patients interviewed cross-sectionally at 1 to more than 10 years since diagnosis, time since cancer diagnosis was not associated with QoL when we considered all germ-cell testicular cancer patients together. When stratified by histology type, we found certain evidence that nonseminoma cases report higher PCS over time since cancer diagnosis.

Head and neck cancer (HNC) is a preventable malignancy that continues to cause substantial morbidity and mortality worldwide. Using data from the ARCAGE and Rome studies, we investigated the main ...predictors of survival after larynx, hypopharynx and oral cavity (OC) cancers. We used the Kaplan–Meier method to estimate overall survival, and Cox proportional models to examine the relationship between survival and sociodemographic and clinical characteristics. 604 larynx, 146 hypopharynx and 460 OC cancer cases were included in this study. Over a median follow‐up time of 4.6 years, nearly 50% (n = 586) of patients died. Five‐year survival was 65% for larynx, 55% for OC and 35% for hypopharynx cancers. In a multivariable analysis, we observed an increased mortality risk among older (≥71 years) versus younger (≤50 years) patients with larynx/hypopharynx combined (LH) and OC cancers HR = 1.61, 95% CI 1.09–2.38 (LH) and HR = 2.12, 95% CI 1.35–3.33 (OC), current versus never smokers HR = 2.67, 95% CI 1.40–5.08 (LH) and HR = 2.16, 95% CI 1.32–3.54 (OC) and advanced versus early stage disease at diagnosis IV versus I, HR = 2.60, 95% CI 1.78–3.79 (LH) and HR = 3.17, 95% CI 2.05–4.89 (OC). Survival was not associated with sex, alcohol consumption, education, oral health, p16 expression, presence of HPV infection or body mass index 2 years before cancer diagnosis. Despite advances in diagnosis and therapeutic modalities, survival after HNC remains low in Europe. In addition to the recognized prognostic effect of stage at diagnosis, smoking history and older age at diagnosis are important prognostic indicators for HNC.
What's new?
Most people diagnosed with head and neck cancer do not survive to the 8‐year mark. These authors examined which factors correlate with survival after cancer of the larynx, hypopharynx or oral cavity. They found increased mortality among patients over age 70 years, current smokers, and those with advanced disease. Stage at diagnosis is one of the strongest predictors of survival, but even with modern detection methods, most patients in Europe are still diagnosed with advanced disease.
PURPOSE There is a need to better understand prostate cancer progression and identify new prognostic markers for this tumor. We investigated the association between promoter methylation in a priori ...selected genes and survival in two independent large series of prostate cancer patients. METHODS We followed up with two cohorts of patients (216 patients diagnosed in 1982 to 1988 and 243 patients diagnosed in 1993 to 1996) diagnosed at one hospital pathology ward in Turin, Italy. DNA was obtained from paraffin-embedded tumor tissues and evaluated for promoter methylation status in glutathione S-transferase (GSTP1), adenomatous polyposis coli (APC), and runt-related transcription factor 3 (RUNX3). Results The two cohorts had different prevalences of methylation in APC (P = .047), GSTP1 (P = .002), and RUNX3 (P < .001). Methylation in APC was associated with an increased risk of prostate cancer-specific mortality (hazard ratio HR = 1.42; 95% CI, 0.98 to 2.07 in the 1980s cohort; HR = 1.57; 95% CI, 0.95 to 2.62 in the 1990s cohort; HR = 1.49; 95% CI, 1.11 to 2.00 in the two cohorts combined). In subgroup analyses, the HRs were higher among patients with a Gleason score less than 8 (HR = 1.52; 95% CI, 0.85 to 2.73 in the 1980s cohort; HR = 2.09; 95% CI, 1.02 to 4.28 in the 1990s cohort). Methylation in RUNX3 was associated with prostate cancer mortality only in the 1990s cohort, and methylation in GSTP1 did not predict mortality in either cohort. CONCLUSION The pattern of hypermethylation may have changed after the introduction of prostate-specific antigen testing in the beginning of the 1990s. Promoter methylation in APC was identified as a marker for prostate cancer progression.
In the past, increases in childhood cancer incidence were reported in Europe and North America. The aim of this study is to show updated patterns of temporal behavior using data of the Childhood ...Cancer Registry of Piedmont (CCRP), a region with approximately 4.5 million inhabitants in North-West Italy. CCRP has been recording incident cases in children (0-14 years) since 1967 and in adolescents (15-19) since 2000. Time trends were estimated as annual percent change (APC) over the 1976-2011 period for children, and over 2000-2011 for both children and adolescents. CCRP registered 5020 incident cases from 1967 to 2011. Incidence rates were 157 per million person-years for children (1967-2011) and 282 for adolescents (2000-2011). From 1976-2011, increasing trends were observed in children for all neoplasms (APC 1.1, 95%CI: 0.8; 1.5) and for both embryonal and non-embryonal tumors: 1.1%, (0.5; 1.6) and 1.2%, (0.7; 1.6), respectively. Increases were observed in several tumor types, including leukemia, lymphoma, central nervous system tumors and neuroblastoma. In 2000-2011, incidence rates showed mostly non statistically significant variations and large variability. The observation of trends over a long period shows that the incidence of most tumors has increased, and this is only partially explained by diagnostic changes. Large rate variability hampers interpretation of trend patterns in short periods. Given that no satisfying explanation for the increases observed in the past was ever found, efforts must be made to understand and interpret this peculiar and still ununderstood pattern of childhood cancer incidence.

Several studies have reported a reduction in acute coronary events (ACEs) in the general population after the enforcement of smoking regulations, although there is uncertainty concerning the ...magnitude of the effect of such interventions. We conducted a country-wide evaluation of the health effects of the introduction of a smoking ban in public places, using data on hospital admissions for ACEs from the Italian population after the implementation of a national smoking regulation in January 2005.
Rates of admission for ACEs in the 20 Italian regions from January 2002 to November 2006 were analysed using mixed-effect regression models that allowed for long-term trends and seasonality. Standard methods for interrupted time-series were adopted to assess the immediate and gradual effects of the smoking ban. Effect modification by age was investigated, with the assumption that exposure to passive smoking in public places would be greater among young people. In total, 936,519 hospital admissions for ACEs occurred in the Italian population during the study period. A 4% reduction in hospital admissions for ACEs among persons aged less than 70 years was evident after the introduction of the ban (Rate Ratio RR, 0.96; 95% Confidence Interval CI, 0.95-0.98). No effect was found among persons aged at least 70 years (RR 1.00; 95% CI 0.99-1.02). Effect modification by age was further suggested by analyses using narrower age categories.
Smoke-free policies can constitute a simple and inexpensive intervention for the prevention of cardiovascular diseases and thus should be included in prevention programmes.

Human papillomavirus (HPV) is causally implicated in a subset of cancers of the upper aero-digestive tract (UADT).
Associations between type-specific HPV antibodies were examined among 1496 UADT ...cancer case subjects and 1425 control subjects by estimating odds ratios (ORs) in logistic regression analyses adjusted for potential confounders. The agreement between serology and tumor markers of HPV infection, including presence of HPV DNA and p16 expression, were examined in a subset of tumors.
HPV16 L1 seropositivity was associated with increased risk of oral cavity and oropharyngeal cancer (OR = 1.94, 95% confidence interval CI = 1.03 to 3.65; OR = 8.60, 95% CI = 5.21 to 14.20, respectively). HPV16 E6 antibodies were present in 30.2% of oropharyngeal case subjects and only 0.8% of control subjects (OR = 132.0, 95% CI = 65.29 to 266.86). Combined seropositivity to HPV16 E6 and E7 was rare (n = 1 of 1425 control subjects). An agreement of 67% was observed between HPV16 E6 serology and the corresponding presence of an HPV-related cancer: four of six HPV DNA-positive/p16-overexpressing tumors were HPV16 E6 antibody positive. An HPV16 independent association was observed for HPV18 and oropharyngeal cancer (OR = 8.14, 95% CI = 2.21 to 29.99 for HPV18 E6 seropositivity) and HPV6 and laryngeal cancer (OR = 3.25, 95% CI = 1.46 to 7.24 for HPV6 E7 seropositivity).
These results confirm an important role for HPV16 infection in oropharyngeal cancer. HPV16 E6 antibodies are strongly associated with HPV16-related oropharyngeal cancers. Continuing efforts are needed to consider both HPV serology and p16 staining as biomarkers relevant to the etiology and natural history of HPV16-related oropharyngeal tumors. These results also support a marginal role for HPV18 in oropharyngeal cancer and HPV6 in laryngeal cancer.
Invasive candida infections are an important cause of morbidity in low-birth-weight infants (<1500 g). In this randomized, double-blind, placebo-controlled trial, 322 infants received either placebo ...or fluconazole from birth until day 30 of life (day 45 for neonates who weighed <1000 g at birth). The incidence of invasive fungal infections was 13.2% in the placebo group and 3.2% in the fluconazole groups combined; the difference was statistically significant.
Low-birth-weight infants received either placebo or fluconazole from birth until day 30 of life. The incidence of invasive fungal infections was 13.2% in the placebo group and 3.2% in the fluconazole groups.
Despite efforts to improve the outcomes of preterm infants, systemic fungal diseases caused mainly by candida species are an important complication of the care of neonates on the threshold of viability. Candida species colonize up to 60% of very-low-birth-weight neonates (those weighing less than 1500 g) during their first month in the neonatal intensive care unit (NICU). Such colonization may progress to invasive fungal infection in up to 20% of these infants.

Nonspecific clinical features, poor sensitivity of diagnostic tests, and late recognition mean that at the time of diagnosis invasive fungal infection is often advanced. Such infections increase . . .
Although several oropharyngeal cancer (OPC) susceptibility loci have been identified, most previous studies lacked detailed information on human papillomavirus (HPV) status. We conduct a genome-wide ...analysis by HPV16 serology status in 4,002 oral cancer cases (OPC and oral cavity cancer (OCC)) and 5,256 controls. We detect four susceptibility loci pointing to a distinct genetic predisposition by HPV status. Our most notable finding in the HLA region, that is now confirmed to be specific of HPV(+)OPC risk, reveal two independent loci with strong protective effects, one refining the previously reported HLA class II haplotype association. Antibody levels against HPV16 viral proteins strongly implicate the protective HLA variants as major determinants of humoral response against L1 capsid protein or E6 oncoprotein suggesting a natural immune response against HPV(+)OPC promoted by HLA variants. This indicates that therapeutic vaccines that target E6 and attenuate viral response after established HPV infections might protect against HPV(+)OPC.
In many centers, Stage I–II melanoma patients are considered “cured” after 10 years of disease‐free survival and follow‐up visits are interrupted. However, melanoma may relapse also later. We ...retrospectively analyzed a cohort of 1,372 Stage I–II melanoma patients who were disease‐free 10 years after diagnosis. The aim of this study was to characterize patients who experienced a late recurrence and to compare them to those who remained disease‐free to identify possible predictive factors. Multivariate Cox proportional‐hazards regression analyses were carried out to evaluate the influence of different factors on the risk of recurrence. Seventy‐seven patients out of 1,372 (5.6%) relapsed, 52 in regional sites and 25 in distant ones. The majority of patients (31 out of 52) experienced late recurrence in regional lymph nodes. Brain and lung were the most common site of single distant recurrence (24% each). Patients with multiple distant metastases showed a brain and lung involvement in, respectively, 40 and 48% of cases. A Cox proportional‐hazards regression model analysis showed the independent role of age under 40 years, Breslow thickness >2 mm, and Clark Level IV/V in increasing the risk of Late Recurrence. These patients should be followed‐up for longer than 10 years. The pattern of recurrence suggests that melanoma cells can be dormant preferentially in lymph nodes, brain and lung. A particular attention should be reserved to these anatomic sites during the follow‐up after 10 years of disease‐free.
What's new?
After a period of apparent cure lasting 10 or more years, a small percentage of melanoma patients experience late recurrence, in which dormant tumor cells reemerge to cause disease. The factors that precipitate recurrence are unclear, however. In this study, risk of late recurrence in melanoma was found to be elevated among stage I‐II patients who were under age 40 at diagnosis and had a Breslow thickness of more than 2 mm or a Clark level IV/V. The regional lymph nodes, brain, and lungs were primary sites of recurrence, suggesting that they are preferential sites of tumor cell dormancy.
