Background Increasing proportions of patients diagnosed with cancer will become long-term survivors (≥5 years post-diagnosis). However, survivors may continue to experience negative effects of cancer and/or treatment, including fear of recurrence (FoR). This review aims to provide an overview of current knowledge on FoR, including determinants and consequences in long-term cancer survivors, and to outline methodological and conceptual challenges that should be addressed in future research. Methods Multiple databases including PUBMED, EMBASE, and PsycINFO were searched to identify relevant articles. Seventeen articles were included. Data were extracted by two reviewers and summarized following a systematic scheme. Results Even years after initial diagnosis, cancer survivors suffer from FoR. Most studies report low or moderate mean FoR scores, suggesting that FoR is experienced in modest intensity by most survivors. Studies including long-term and short-term survivors indicate no significant change of FoR over time. Lower level of education, lower level of optimism, and being Hispanic or White/Caucasian were found to be associated with higher levels of FoR. Significant negative associations were reported between FoR and quality of life as well as psychosocial well-being. All but three studies were conducted in the USA. General cut-offs for severity/clinical significance have not been defined yet. Conclusions FoR at modest intensity is experienced by most long-term cancer survivors. Future studies should address determinants and consequences of FoR in more detail. Validated instruments providing cut-offs for severity/clinical significance of FoR should be developed and utilized. Efficient interventions should be implemented to reduce detrimental effects of FoR. Copyright © 2012 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

Primary amebic meningoencephalitis (PAM) is a rare and lethal infection caused by Naegleria fowleri. We report an epidemiological and environmental investigation relating to a case of PAM in a previously healthy boy age 8 years. An interview of the patient's family was conducted to determine the likely exposure site and to assess risk factors. Data from the United States Geological Survey site at Waterloo, NE, on the Elkhorn River were used to estimate water temperature and streamflow at the time and site of exposure. Data from the National Weather Service were used to estimate precipitation and ambient air temperature at the time and site of exposure. Despite conventional treatment, the patient died 2 days after hospital admission. The patient participated in recreational water activities in the Elkhorn River in northeastern Nebraska 5 days before symptom onset. In the week before exposure, water and ambient air high temperatures reached annual highs, averaging 32.4°C and 35.8°C, respectively. The day before infection, 2.2 cm of precipitation was reported. Streamflow was low (407 ft3/s). Infections in several northern states, including Nebraska, suggest an expanding geographic range of N. fowleri transmission, which may lead to increased incidence of PAM in the United States. Similar environmental investigations at suspected exposure sites of future cases will allow data aggregation, enabling investigators to correlate environmental factors with infection risk accurately.

During February 7─September 3, 2022, a total of 39 US states experienced outbreaks of highly pathogenic avian influenza A(H5N1) virus in birds from commercial poultry farms and backyard flocks. Among persons exposed to infected birds, highly pathogenic avian influenza A(H5) viral RNA was detected in 1 respiratory specimen from 1 person.

Objective: This large international cohort study aimed to investigate the associations of examined lymph node (ELN) number with accurate staging and long-term survival in pancreatic adenocarcinoma (PaC) and to robustly determine the minimal and optimal ELN thresholds., Summary Background Data: ELN number is an important quality metric in cancer care. The recommended minimal ELN number in PaC to accurately stage cancer varies greatly across guidelines, and the optimal number especially to adequately stratify patient survival has not yet been established., Methods: Population-based data on patients with stage I to II PaC resected in 2003 to 2015 from the US Surveillance, Epidemiology, and End Results (SEER)-18 Program and Netherlands National Cancer Registry (NCR) were analyzed. Associations of ELN number with stage migration and survival were evaluated using multivariable-adjusted logistic and Cox regression models, respectively. The series of odds ratios (ORs) for negative-to-positive node stage migration and hazard ratios (HRs) for survival with more ELNs were fitted using a LOWESS smoother, and structural breakpoints were determined by Chow test., Results: Overall 16,241 patients were analyzed. With increasing ELN number, both cohorts exhibited significant proportional increases from nodenegative to node-positive disease [ORSEER-18 = 1.05, 95% confidence interval (CI) = 1.04-1.05; ORNCR = 1.10, 95% CI = 1.08-1.12] and serial improvements in survival (HRSEER-18 = 0.98, 95% CI = 0.98-0.99; HRNCR = 0.98, 95% CI = 0.97-0.99) per additional ELN after controlling for confounders. Associations for stage migration and survival remained significant in most stratifications by patient, tumor, and treatment factors. Cut-point analyses suggested a minimal threshold ELN number of 11 and an optimal number of 19, which were validated both internally in the derivative US cohort and externally in the Dutch cohort with the ability to well discriminate different probabilities of both survival and stage migration., Conclusions: In stage I to II PaC, more ELNs are associated with more precise nodal staging, which might largely explain the survival association. Our observational study does not suggest causality, and does not encourage more extended lymphadenectomy before further randomized evidence is obtained. Our results robustly conclude 11 ELNs as the minimal and suggest 19 ELNs as the optimal cut-points, for evaluating quality of lymph node examination and possibly for stratifying postoperative prognosis., Competing Interests: The authors report no conflicts of interest., (Copyright © 2019 Wolters Kluwer Health, Inc.

Evidence on survival of malignant mesothelioma (MM) and other rare thoracic cancers is limited due to the rarity of these cancer sites. Here, we provide a comprehensive overview of MM incidence and survival after MM and other rare thoracic cancers in Germany and the United States (US). Incidence was estimated from a German National Cancer Database and from the Surveillance, Epidemiology and End Results (SEER) 18 database for 2000-2014. Patients diagnosed in 1997-2013 with malignant epithelial tumors of the trachea (Etra), epithelial tumors of the thymus (Ethy) and MM were extracted from a German cancer survival database and from the SEER 13 database. Period analysis was employed to compute 5-year relative survival (RS). During 2000-2014, an annual average of 0.9 and 0.6 MM cases per 100,000 person-years was diagnosed in Germany and the US. Rates decreased in Germany and in the US. Patients with Ethy had highest 5-year RS with US patients surviving longer (69.1% compared to 63.7%, p = 0.02). Survival after Etra was comparable in both countries (Germany 33.6%, US 34.4%, p = 0.07). Survival in MM patients was poor overall (Germany 11.8%, US 12.1%, p < 0.01). Survival improvements were only observed in MM patients in Germany (10.8% [2002-2007] vs. 13.0% [2008-2013], p < 0.01). The lack of progress in survival for Etra and Ethy patients underlines the need of novel preventive, therapeutic and diagnostic approaches. MM incidence significantly decreased in Germany and in the US. Further monitoring of MM incidence is warranted given that a peak in incidence is expected in 2020-2030 in Western countries., (© 2020 The Authors.

Background & Aims: Red and processed meat intake is associated with colorectal cancer (CRC) incidence, but it is not clear if intake is associated with patient survival after diagnosis., Methods: We pooled data from 7627 patients with stage I-IV CRC from 10 studies in the International Survival Analysis in Colorectal Cancer Consortium. Cox proportional hazards regression models were used to evaluate the associations of intake of red and processed meat before diagnosis with overall and CRC-specific survival., Results: Among 7627 patients with CRC, 2338 died, including 1576 from CRC, over a median follow-up time of 5.1 years. In multivariable-adjusted analyses, higher intake of red or processed meat was not associated with overall survival of patients with stage I-III CRC: Q4 vs Q1 red meat hazard ratio [HR], 1.08 (95% CI, 0.93-1.26) and Q4 vs Q1 processed meat HR, 1.10 (95% CI, 0.93-1.32) or with CRC-specific survival: Q4 vs Q1 red meat HR, 1.09 (95% CI, 0.89-1.33) and Q4 vs Q1 processed meat HR, 1.11 (95% CI, 0.87-1.42). Results were similar for patients with stage IV CRC. However, patients with stage I-III CRC who reported an intake of processed meat above the study-specific medians had a higher risk of death from any cause (HR, 1.12; 95% CI, 1.01-1.25) than patients who reported eating at or less than the median., Conclusion: In this large consortium of CRC patient cohorts, intake of red and processed meat before a diagnosis of CRC was not associated with shorter survival time after diagnosis, although a possible weak adverse association cannot be excluded. Studies that evaluate dietary data from several time points before and after cancer diagnosis are required to confirm these findings., (Copyright © 2019 AGA Institute. Published by Elsevier Inc.

Objective: Resection can potentially cure resectable pancreatic cancer (PaC) and significantly prolong survival in some patients. This large-scale international study aimed to investigate variations in resection for PaC in Europe and USA and determinants for its utilisation., Design: Data from six European population-based cancer registries and the US Surveillance, Epidemiology, and End Results Program database during 2003-2016 were analysed. Age-standardised resection rates for overall and stage I-II PaCs were computed. Associations between resection and demographic and clinical parameters were assessed using multivariable logistic regression models., Results: A total of 153 698 records were analysed. In population-based registries in 2012-2014, resection rates ranged from 13.2% (Estonia) to 21.2% (Slovenia) overall and from 34.8% (Norway) to 68.7% (Denmark) for stage I-II tumours, with great international variations. During 2003-2014, resection rates only increased in USA, the Netherlands and Denmark. Resection was significantly less frequently performed with more advanced tumour stage (ORs for stage III and IV versus stage I-II tumours: 0.05-0.18 and 0.01-0.06 across countries) and increasing age (ORs for patients 70-79 and ≥80 versus those <60 years: 0.37-0.63 and 0.03-0.16 across countries). Patients with advanced-stage tumours (stage III-IV: 63.8%-81.2%) and at older ages (≥70 years: 52.6%-59.5%) receiving less frequently resection comprised the majority of diagnosed cases. Patient performance status, tumour location and size were also associated with resection application., Conclusion: Rates of PaC resection remain low in Europe and USA with great international variations. Further studies are warranted to explore reasons for these variations., Competing Interests: Competing interests: None declared., (© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2019.

The role of chemotherapy in the treatment of pancreatic cancer (PaC) has been well-established, while radiation plays ambiguous roles. This international large-scale population-based study aimed to investigate the real-world application of chemotherapy and radiotherapy for resected and unresected PaC in Europe and USA. Population-based data from multiple European national cancer registries and the US Surveillance, Epidemiology and End Results (SEER)-18 database during 2003-2014 were analyzed. Temporal trends and geographical variations in the application rates of chemotherapy and radiotherapy were quantified using age standardization. Associations of treatment with demographic and clinical characteristics were assessed using multivariable logistic regression. A total of 141,533 PaC patients were analyzed. From 2003-2005 to 2012-2014, chemotherapy administration rates increased in most countries and more strongly among resected patients, while radiation rates were generally low with a slight decline or no obvious trend. In 2012-2014, 12.5% (Estonia) to 61.7% (Belgium) of resected and 17.1% (Slovenia) to 56.9% (Belgium) of unresected patients received chemotherapy. Radiation was administered in 2.6% (Netherlands) to 32.6% (USA) of resected and 1.0% (USA) to 6.0% (Belgium) of unresected patients. Strong temporal and geographical variations were observed. Patterns and strengths of associations of treatment administration with various demographic and clinical factors differed substantially between resected and unresected cancers and varied greatly across countries. Conclusively, administration of chemotherapy but not radiotherapy for PaC increased during the last decade in Europe and USA. Treatment rates were low and the uptake strongly varied across countries, highlighting the need for standardization in PaC treatment to improve patient care., (© 2018 UICC.)

Hepatobiliary tract cancers (HBTCs) are a heterogeneous group of cancers with high mortality. Because most of these cancers, with the exception of hepatocellular carcinoma (HCC), are rare, few data are available concerning the population level survival expectations of patients with HBTC. Here, we describe survival of patients with HBTC in Germany with comparison to survival in the US. Therefore, data were extracted from 12 databases in Germany and the Surveillance, Epidemiology and End Results (SEER13) database in the US. Period analysis and modeled period analysis were used to calculate 5-year relative survival estimates for patients with HBTC diagnosed from 1997 to 2013. HCC was the most common HBTC in each database, accounting for over 1/3 of HBTC in Germany and about half of cases in the US. Overall age adjusted 5-year relative survival for HBTC in 2006-2013 was 19.1% in Germany and 20.6% in the US. Five-year relative survival increased by 3.8% units in Germany and 4.5% units in the US between 2002-2005 and 2010-2013. Five-year relative survival for individual types of HBTC ranged from 9.8% in Germany and 2.9% in the US for not otherwise specified biliary tract cancers to 44.4% and 50.1%, respectively, in Germany and the US for duodenal cancers. In conclusion, survival for HBTC remains poor in both Germany and the US, although a small increase in survival in the past decade was observed. Further work to find better treatment options for HBTC is needed to improve survival., (© 2018 UICC.)

Introduction: The epidemiology of squamous cell oral cavity and pharyngeal cancers (OCPC) has changed rapidly during the last years, possibly due to an increase of human papilloma virus (HPV) positive tumors and successes in tobacco prevention. Here, we compare incidence and survival of OCPC by HPV-relation of the site in Germany and the United States (US)., Materials and Methods: Age-standardized and age-specific incidence and 5-year relative survival was estimated using data from population-based cancer registries in Germany and the US Surveillance Epidemiology and End Results (SEER) 13 database. Incidence was estimated for each year between 1999 and 2013. Relative survival for 2002-2005, 2006-2009, and 2010-2013 was estimated using period analysis., Results: The datasets included 52,787 and 48,861 cases with OCPC diagnosis between 1997 and 2013 in Germany and the US. Incidence was much higher in Germany compared to the US for HPV-unrelated OCPC and more recently also for HPV-related OCPC in women. Five-year relative survival differences between Germany and the US were small for HPV-unrelated OCPC. For HPV-related OCPC, men had higher survival in the US (62.1%) than in Germany (45.4%) in 2010-2013. These differences increased over time and were largest in younger patients and stage IV disease without metastasis. In contrast, women had comparable survival for HPV-related OCPC in both countries., Conclusions: Strong survival differences between Germany and the US were observed for HPV-related OCPC in men, which might be explained by differences in HPV-attributable proportions. Close monitoring of the epidemiology of OCPC in each country is needed., (Copyright © 2017 Elsevier Ltd. All rights reserved.)

Background: Recent population-based studies in the United States of America (USA) and other countries have shown improvements in survival for patients with chronic lymphocytic leukemia (CLL) diagnosed in the early twenty-first century. Here, we examine the survival for patients diagnosed with CLL in Germany in 1997-2011., Methods: Data were extracted from 12 cancer registries in Germany and compared to the data from the USA. Period analysis was used to estimate 5- and 10-year relative survival (RS)., Results: Five- and 10-year RS estimates in 2009-2011 of 80.2 and 59.5%, respectively, in Germany and 82.4 and 64.7%, respectively, in the USA were observed. Overall, 5-year RS increased significantly in Germany and the difference compared to the survival in the USA which slightly decreased between 2003-2005 and 2009-2011. However, age-specific analyses showed persistently higher survival for all ages except for 15-44 in the USA. In general, survival decreased with age, but the age-related disparity was small for patients younger than 75. In both countries, 5-year RS was >80% for patients less than 75 years of age but <70% for those age 75+., Conclusions: Overall, 5-year survival for patients with CLL is good, but 10-year survival is significantly lower, and survival was much lower for those age 75+. Major differences in survival between countries were not observed. Further research into ways to increase survival for older CLL patients are needed to reduce the persistent large age-related survival disparity.

Objective: Monitoring cancer survival is a key task of cancer registries, but timely disclosure of progress in long-term survival remains a challenge. We introduce and evaluate a novel method, denoted "boomerang method," for deriving more up-to-date estimates of long-term survival., Study Design and Setting: We applied three established methods (cohort, complete, and period analysis) and the boomerang method to derive up-to-date 10-year relative survival of patients diagnosed with common solid cancers and hematological malignancies in the United States. Using the Surveillance, Epidemiology and End Results 9 database, we compared the most up-to-date age-specific estimates that might have been obtained with the database including patients diagnosed up to 2001 with 10-year survival later observed for patients diagnosed in 1997-2001., Results: For cancers with little or no increase in survival over time, the various estimates of 10-year relative survival potentially available by the end of 2001 were generally rather similar. For malignancies with strongly increasing survival over time, including breast and prostate cancer and all hematological malignancies, the boomerang method provided estimates that were closest to later observed 10-year relative survival in 23 of the 34 groups assessed., Conclusion: The boomerang method can substantially improve up-to-dateness of long-term cancer survival estimates in times of ongoing improvement in prognosis., (Copyright © 2016 Elsevier Inc.

Background and Aim: This study aims to examine survival for gastric lymphomas and its main subtypes, mucosa-associated lymphoid tissue lymphoma (MALT), and diffuse large B-cell lymphoma (DLBCL), in Germany and in the United States., Methods: Data for patients diagnosed in 1997-2010 were used from 10 population-based German cancer registries and compared to the data from the US Surveillance, Epidemiology and End Results (SEER) 13 registries database. Patients age 15-74 diagnosed with gastric lymphomas were included in the analysis. Period analysis and modeled period analysis were used to estimate 5-year and 10-year relative survival (RS) in 2002-2010 and survival trends from 2002-2004 to 2008-2010., Results: Overall, the database included 1534 and 2688 patients diagnosed with gastric lymphoma in 1997-2010 in Germany and in the United States, respectively. Survival was substantially higher for MALT (5-year and 10-year RS: 89.0% and 80.9% in Germany, 93.8% and 86.8% in the United States) than for DLBCL (67.5% and 59.2% in Germany, and 65.3% and 54.7% in the United States) in 2002-2010. Survival was slightly higher among female patients and decreased by age for gastric lymphomas combined and its main subtypes. A slight, nonsignificant, increase in the 5-year RS for gastric lymphomas combined was observed in Germany and the United States, with increases in 5-year RS between 2002-2004 and 2008-2010 from 77.1% to 81.0% and from 77.3% to 82.0%, respectively. Five-year RS of MALT exceeded 90% in 2008-2010 in both countries., Conclusions: Five-year RS of MALT meanwhile exceeds 90% in both Germany and the United States, but DLBCL has remained below 70% in both countries., (© 2015 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.)

The monitoring of cancer survival by population-based cancer registries is a prerequisite to evaluate the current quality of cancer care. Our study provides 1-, 5- and 10-year relative survival as well as 5-year relative survival conditional on 1-year survival estimates and recent survival trends for Germany using data from 11 population-based cancer registries, covering around one-third of the German population. Period analysis was used to estimate relative survival for 24 common and 11 less common cancer sites for the period 2007-2010. The German and the United States survival estimates were compared using the Surveillance, Epidemiology and End Results 13 database. Trends in cancer survival in Germany between 2002-2004 and 2008-2010 were described. Five-year relative survival increased in Germany from 2002-2004 to 2008-2010 for most cancer sites. Among the 24 most common cancers, largest improvements were seen for multiple myeloma (8.0% units), non-Hodgkin lymphoma (6.2% units), prostate cancer (5.2% units) and colorectal cancer (4.6% units). In 2007-2010, the survival disadvantage in Germany compared to the United States was largest for cancers of the mouth/pharynx (-11.0% units), thyroid (-6.8% units) and prostate (-7.5% units). Although survival estimates were much lower for elderly patients in both countries, differences in age patterns were observed for some cancer sites. The reported improvements in cancer survival might reflect advances in the quality of cancer care on the population level as well as increased use of screening in Germany. The survival differences across countries and the survival disadvantage in the elderly require further investigation., (© 2014 UICC.)

Background: New treatment options and supportive care measures have greatly improved survival of patients with non-Hodgkin lymphoma (NHL) but may not be affordable for those with no insurance or inadequate insurance., Methods: Using data from the Surveillance, Epidemiology, and End Results database, we estimated overall and cause-specific survival according to insurance status within 3 years after diagnosis of patients diagnosed with NHL in the U.S. in the period 2007-2011. Because NHL is a heterogeneous condition, we also examined survival in diffuse large B-cell lymphoma (DLBCL)., Results: Survival was higher for patients with non-Medicaid insurance compared with either uninsured patients or patients with Medicaid. For patients with any NHL, the 3-year survival estimates were 68.0% for uninsured patients, 60.7% for patients with Medicaid, and 84.9% for patients with non-Medicaid insurance. Hazard ratios (HRs) for uninsured and Medicaid-only patients compared with insured patients were 1.92 (95% confidence interval [CI]: 1.76-2.10) and 2.51 (95% CI: 2.36-2.68), respectively. Results were similar for patients with DLBCL, with survival estimates of 68.5% for uninsured patients (HR: 1.78; 95% CI: 1.57-2.02), 58%, for patients with Medicaid (HR: 2.42; 95% CI: 2.22-2.64), and 83.3% for patients with non-Medicaid insurance. Cause-specific analysis showed survival estimates of 80.3% for uninsured patients (HR: 1.83; 95% CI: 1.62-2.05), 77.7% for patients with Medicaid (HR: 2.23; 95% CI: 2.05-2.42), and 90.5% for patients with non-Medicaid insurance., Conclusion: Lack of insurance and Medicaid only were associated with significantly lower survival for patients with NHL. Further evaluation of the reasons for this disparity and implementation of comprehensive coverage for medical care are urgently needed., (©AlphaMed Press.)

Purpose: This study examines the perceived level of stress and burnout among health science educators related to smart device use., Methods: An interdisciplinary health science research team was created to perform a literature review and design a survey and assessment instrument to investigate the level of stress and burnout among health science educators as a result of excessive connectivity to the workplace through smart device use. A total of 977 assessments were completed through distribution by program directors in athletic training, nursing, radiologic sciences, and respiratory care., Results: Participants in the study, who represented program directors and educators in the allied health sciences, reported 70% of their smart device use taking place between the hours of 6 am and 6 pm, followed by 30% between 6 pm and 12 am. Slightly more than 60% of participants reported feeling connected to the workplace at all hours of the day. Emotional exhaustion and personal accomplishment scores for participants were stronger than the norm as measured by the Maslach Burnout Inventory., Discussion: There appears to be a strong feeling of connectedness to the workplace caused by the use of smart devices (60.7%). Some surveyed educators appear to manage their smart device use better than others because 55% of participants indicated they sometimes ignore work-related items after hours. Although several participants demonstrated physical signs of stress and burnout, a causal relationship between use of smart devices or work connectedness could not be established., Conclusion: Based on the findings of this study, the null hypothesis was rejected. Significant levels of emotional exhaustion were seen in a subset of study participants. Our findings indicate that emotional exhaustion occurs when healthy boundaries are not maintained for smart device use for work purposes after hours.

Background: Adulthood acute lymphoblastic leukemia (ALL) is a rare disease. In contrast to childhood ALL, survival for adults with ALL is poor. Recently, new protocols, including use of pediatric protocols in young adults, have improved survival in clinical trials. Here, we examine population level survival in Germany and the United States (US) to gain insight into the extent to which changes in clinical trials have translated into better survival on the population level., Methods: Data were extracted from the Surveillance, Epidemiology, and End Results database in the US and 11 cancer registries in Germany. Patients age 15-69 diagnosed with ALL were included. Period analysis was used to estimate 5-year relative survival (RS)., Results: Overall 5-year RS was estimated at 43.4% for Germany and 35.5% for the US (p = 0.004), with a decrease in survival with increasing age. Survival was higher in Germany than the US for men (43.6% versus 37.7%, p = 0.002) but not for women (42.4% versus 40.3%, p>0.1). Five-year RS estimates increased in Germany and the US between 2002 and 2006 by 11.8 and 7.3 percent units, respectively (p = 0.02 and 0.04, respectively)., Conclusions: Survival for adults with ALL continues to be low compared with that for children, but a substantial increase in 5-year survival estimates was seen from 2002 to 2006 in both Germany and the US. The reasons for the survival differences between both countries require clarification.

Introduction: The advent of tyrosine kinase inhibitors has produced 5-year survival of 90 + % for chronic myelocytic leukemia (CML) patients in clinical trials. However, population level survival has been lower, especially in older patients. Here, we examine survival of patients with CML in Germany and compare it to survival of patients in the United States (US)., Methods: Data were extracted from the Surveillance, Epidemiology, and End Results database in the US and 11 cancer registries in Germany. Patients 15-69 years old diagnosed with CML were included in the analysis. Period analysis for 2002-2006 was used to provide the most up-to-date possible estimates of five-year relative survival., Results: Five-year relative survival was 68.7% overall in Germany and 72.7% in the US. Survival was higher in the US for all age groups except for ages 15-39 years, but the difference was only statistically significant for ages 50-59 years (at 67.5% vs 77.7% in Germany and the US, respectively). Survival decreased with age, ranging from 83.1% and 81.9%, respectively, in Germany and the US for patients 15-39 years old to 54.2% and 54.5%, respectively, in patients 65-69 years old. Survival increased between 2002 and 2006 by 12.0% points in Germany and 17.1% points in the US., Conclusions: Five-year survival estimates were higher in the US than in Germany overall, but the difference was only significant for ages 50-59 years. Survival did not equal that seen in clinical trials for either country, but strong improvement in survival was seen between 2002 and 2006.

Introduction: The aim of this study was to provide detailed age-specific (5-year age groups) and histology-specific (histologic subtypes of seminoma and nonseminoma) relative survival estimates of testicular germ cell cancer patients in Germany and the United States (U.S.) for the years 2002-2006 and to compare these estimates between countries., Methods: We pooled data from 11 cancer registries of Germany and used data from the U.S. (SEER-13 database) including 11,508 and 10,774 newly diagnosed cases (1997-2006) in Germany and the U.S., respectively. We estimated 5-year relative survival (5-year-RS) by histology and age based on period analysis., Results: 5-year-RS for testicular germ cell tumors was 96.7% and 96.3% in Germany and the U.S., respectively. 5-Year-RS for spermatocytic seminoma was close to 100% in both countries. 5-Year-RS for nonseminoma was lower than for classical seminoma in Germany (93.3% versus 97.6%) and the U.S. (91.0% versus 98.2%). Among nonseminomas, choriocarcinomas provided the lowest 5-year-RS in both countries (Germany 80.1%, U.S. 79.6%). Age-specific 5-year-RS for seminoma showed only little variation by age. 5-Year-RS for nonseminomas tended to be lower at higher ages, especially for malignant teratoma., Discussion: This is the first study that provides up-to-date survival estimates for testicular cancer by histology and age in Germany and the U.S. Survival after a diagnosis of testicular cancer is very comparable between Germany and the U.S. 5-Year-RS for spermatocytic seminoma was close to 100% and the lowest 5-year-RS occurred among choriocarcinoma. Higher age at diagnosis is associated with a poorer prognosis among nonseminoma patients., (Copyright © 2013 Elsevier Ltd. All rights reserved.)

This study provides up-to-date and detailed cancer survival estimates of German patients with non-Hodgkin lymphoma (NHL, International Statistical Classification of Diseases 10th Revision [ICD-10] codes C82-C85) based on data from 11 cancer registries. Period analysis was used to calculate 5-year relative survival in 2002-2006, overall and by gender, age and histology. Comparison was made with patients with NHL in the United States (US) Surveillance, Epidemiology and End Results database in the same time period. Overall 5-year relative survival for patients with NHL in Germany in 2002-2006 was 62.8% and in the US was 65.1%. Survival decreased with age from 81.7% at age 15-49 to 46.5% at age 75+. Survival in the US was 75.3% at age 15-49 and 52% at age 75+. Survival was higher for women than for men, at 65.2% for women and 60.7% for men. Survivals for diffuse B-cell lymphoma and follicular lymphoma, the two most common subtypes of NHL, were 57.3% and 77.5%, respectively. Between 2002 and 2006, overall 5-year relative survival increased by 5.3 percentage points. We conclude that survival for NHL is increasing in Germany in recent years. Survival was higher in Germany than in the US for patients aged 15-49 but lower for older patients.

Background: The proportion of cases notified by death certificate only (DCO) is a commonly used criterion to judge completeness of cancer registration even though it is affected by additional factors, particularly during initial years of newly established registries., Methods: Based on cancer registry data from the United States, we provide model calculations to demonstrate the magnitude and time course of the impact of the following mechanisms on DCO proportions of "young" registries: registration of cancer deaths from patients diagnosed prior to the registration period and delayed registration by death certificate of patients diagnosed but not reported after initiation of registration., Results: DCO proportions of up to ≥30% can be expected from deaths of previously diagnosed patients during the first year of registration. Although this proportion is expected to gradually diminish over subsequent years, DCO proportions may be dominated for several years by this source, which may still be relevant after 10 or more years of cancer registration for cancers with relatively large proportions of late deaths. Otherwise, however, underreporting during patients' lifetime is expected to become the predominant source of DCO proportions in the long run., Conclusions: Our results may guide interpretation of DCO proportions of relatively "young" cancer registries., (Copyright © 2012 Elsevier Ltd.

The survival of younger patients with acute leukemia has improved in the early 21(st) century, but it is unknown whether people of all ethnic and racial backgrounds have benefited equally. Using cancer registry data from the Surveillance, Epidemiology and End Results Program, we assessed trends in 5-year relative survival for patients aged 15 years or more with acute lymphoblastic leukemia and acute myeloblastic leukemia divided by racial and ethnic group, including non-Hispanic whites, African-Americans, Hispanics, and Asian-Pacific Islanders in the 1990s and the early 21(st) century. Modeled period analysis was used to obtain the most up-to-date estimates of survival. Overall, the 5-year survival increased from 31.6% in 1997-2002 to 39.0% in 2003-2008 for patients with acute lymphoblastic leukemia and from 15.5% in 1991-1996 to 22.5% in 2003-2008 for those with acute myeloblastic leukemia. Nevertheless, among patients with acute lymphoblastic leukemia, age-adjusted 5-year relative survival rates remained lower for African-Americans and Hispanics than for non-Hispanic whites. Among patients with acute myeloblastic leukemia, the increase in survival was greatest (from 32.6% in 1991-1996 to 47.1% in 2003-2008) for younger patients (15-54 years), and was more pronounced for non-Hispanic whites (+16.4% units) than for other patients (+10.8% units). Increases in survival are observed in all ethnic or racial groups. Nevertheless, among patients with acute leukemias, disparities in survival persist between non-Hispanic white people and people of other ethnic or racial groups. Disparities are increasing in younger patients with acute myeloblastic leukemia. Improvements in access to treatment, especially for minority patients, may improve outcomes.

Background: Esophagus and stomach cancers are associated with poor prognosis. But most published population-based cancer survival estimates for stomach and esophagus cancer refer to survival experience of patients diagnosed in the 1990s or earlier years. The aim of this study was to provide up-to-date survival estimates and trends for patients with stomach and esophagus cancer in Germany., Material and Methods: Our analysis is based on data from 11 population-based cancer registries, covering 33 million inhabitants. Patients diagnosed with stomach and esophagus cancer in 1997-2006 were included. Period analysis was used to derive five-year relative survival estimates and trends by age, sex, cancer subsite, and stage for the time period of 2002-2006. German and US survival estimates were compared utilizing the SEER 13 database., Results: Overall age-standardized five-year relative survival was 31.8% and 18.3% for stomach and esophagus cancer, respectively, compared to 27.2% and 17.4% in the US. Survival was somewhat higher among female than among male patients for both cancer sites (33.6% vs. 30.6% and 21.5% vs. 17.5%, respectively) and much higher for non-cardia stomach cancer (40.4%) than for cardia cancer (23.4%). From 2002 to 2006, a moderate increase in five-year relative survival by 2.7 percent units was observed for non-cardia stomach cancer patients in Germany (p < 0.001)., Conclusion: Five-year relative cancer survival has reached levels around 40% for patients with non-cardia stomach cancer in Germany in the early 21st century, whereas it remained at lower levels around 20% for patients with esophagus and cardia cancer.

Between 5% and 10% of women who survive a first primary breast cancer will subsequently develop a second primary cancer in the contralateral breast. The Women's Environment, Cancer, and Radiation Epidemiology Study was designed to identify genetic and environmental determinants of contralateral breast cancer (CBC). In this study, 708 women with asynchronous CBC served as cases and 1,397 women with unilateral breast cancer served as controls. ATM, a serine-threonine kinase, controls the cellular response to DNA double-strand breaks, and has been implicated in breast cancer risk. Complete mutation screening of the ATM gene in all 2,105 study participants identified 240 distinct sequence variants; only 15 were observed in >1% of subjects. Among the rare variants, deleterious alleles resulting in loss of ATM function were associated with a nonsignificant increase in risk of CBC. In contrast, carriers of common variants had a statistically significant reduction in risk of CBC. Four of these 15 variants were individually associated with a significantly decreased risk of second primary breast cancer [c.1899-55T>G, rate ratio (RR), 0.5; 95% confidence interval (CI), 0.3-0.8; c.3161C>G, RR, 0.5; 95% CI, 0.3-0.9; c.5558A>T, RR, 0.2; 95% CI, 0.1-0.6; c.6348-54T>C RR, 0.2; 95% CI, 0.1-0.8]. These data suggest that some alleles of ATM may exert an antineoplastic effect, perhaps by altering the activity of ATM as an initiator of DNA damage responses or a regulator of p53.

Epidemiologic studies of breast and other cancers are increasingly turning toward large, multi-center designs in order to obtain adequate power to detect low-penetrance susceptibility alleles. The size of such studies often makes it necessary to distribute the genetic screening efforts to multiple sites. Careful standardization of screening methodology and quality control across sites is required for such multi-center screening designs to be efficient. In this report, we illustrate our approach to these challenges in the context of the WECARE (Women's Environment, Cancer and Radiation Epidemiology) Study, a multi-center population-based genetic epidemiologic study of women with unilateral and bilateral breast cancer. We provide optimized conditions for screening the ataxia-telangiectasia gene (ATM) for variation by denaturing high-performance liquid chromatography (DHPLC) and describe the results of two independent quality control studies at four international centers employing these conditions. Finally, we report novel mutations in the ATM gene identified both in patients with ataxia-telangiectasia and in patients with unilateral or bilateral breast cancer., (Copyright 2003 Wiley-Liss, Inc.)

A dialogue between two lesbian women is conducted in an effort to demonstrate the differences in attitude and level of tolerance towards lesbians in the United States as compared to those in The Netherlands. Their observations suggest there are positive and negative aspects to being a lesbian in both countries and they hope that the positive benefits in both countries will combine.
