[PMID: 39099322 DOI: 10.2340/1651-226x.2024.40823] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2024] [Accepted: 07/04/2024] [Indexed: 08/06/2024]
Abstract
BACKGROUND AND PURPOSE Changes in treatment approaches, characterised by the shift from laryngectomy to a focus on organ-preserving methods may have potentially resulted in lower survival. We aim to identify differences in survival trends for laryngeal cancer (LC) in the Nordic countries over a period of 50 years, and discuss the potential impact of factors such as changes in treatment protocols. MATERIALS AND METHODS Five-year relative survival (RS) data from 1972 to 2021 were obtained from the NORDCAN database 2.0 which included 33,692 LC cases, of which 85% were diagnosed among men. In the NORDCAN database, the age-standardised RS is calculated using the Pohar Perme estimator with individual International Cancer Survival Standards weights. Joinpoint regression models were used to assess potential shifts in trend over the years in RS. RESULTS While Denmark and Norway demonstrated an increasing trend in 5-year RS from 1972 to 2021, in Finland and Sweden, the 5-year RS among men remained static, without any discernible significant trend. Over the 30-year period from 1992-1996 to 2017-2021, RS improved by 9, 4, 13, and 2 percentage points in Denmark, Finland, Norway, and Sweden, respectively. Among women in Sweden, a linear negative trend was observed, noticeable as a 16 percentage-point decline in 5-year RS from the earliest to the latest period. INTERPRETATION The underlying causes for the differences in survival trends remain unclear. Besides differences in treatment protocols, several other factors can affect RS making the interpretation of RS trends challenging.

Abstract
BACKGROUND AND PURPOSE Stage at cancer diagnosis is an important predictor of cancer survival. TNM stage is constructed for anatomic solid cancer diagnoses from tumor size (T), nodal spread (N) and distant metastasis (M) and categorized in groups 0-I, II, II and IV. TNM stage is imperative in cancer diagnosis, management and control, and of high value in cancer surveillance, for example, monitoring of stage distributions. This study yields an overview of TNM availability and trends in stage distribution in the Nordic countries for future use in monitoring and epidemiologic studies. MATERIAL AND METHODS TNM information was acquired from the cancer registries in Denmark, Norway, Sweden, and Iceland during 2004-2016 for 26 cancer sites in the three former countries and four in Iceland. We studied availability, comparability, and distribution of TNM stage in three periods: 2004-2008, 2009-2013, and 2014-2016, applying a previously validated algorithm of 'N0M0 for NXMX'. For cancers of colon, rectum, lung, breast, and kidney, we examined TNM stage-specific 1-year relative survival to evaluate the quality in registration of TNM between countries. RESULTS Denmark, Sweden, and Iceland exhibited available TNM stage proportions of 75-95% while proportions were lower in Norway. Proportions increased in Sweden over time but decreased in Denmark. One-year relative survival differed substantially more between TNM stages than between countries emphasizing that TNM stage is an important predictor for survival and that stage recording is performed similarly in the Nordic countries. INTERPRETATION Assessment and registration of TNM stage is an imperative tool in evaluations of trends in cancer survival between the Nordic countries.

Abstract
BACKGROUND Since the early 2000s, overall and site-specific cancer survival have improved substantially in the Nordic countries. We evaluated whether the improvements have been similar across countries, major cancer types, and age groups. MATERIAL AND METHODS Using population-based data from the five Nordic cancer registries recorded in the NORDCAN database, we included a cohort of 1,525,854 men and 1,378,470 women diagnosed with cancer (except non-melanoma skin cancer) during 2002-2021, and followed for death until 2021. We estimated 5-year relative survival (RS) in 5-year calendar periods, and percentage points (pp) differences in 5-year RS from 2002-2006 until 2017-2021. Separate analyses were performed for eight cancer sites (i.e. colorectum, pancreas, lung, breast, cervix uteri, kidney, prostate, and melanoma of skin). RESULTS Five-year RS improved across nearly all cancer sites in all countries (except Iceland), with absolute differences across age groups ranging from 1 to 21 pp (all cancer sites), 2 to 20 pp (colorectum), -1 to 36 pp (pancreas), 2 to 28 pp (lung), 0 to 9 pp (breast), -11 to 26 pp (cervix uteri), 2 to 44 pp (kidney), -2 to 23 pp (prostate) and -3 to 30 pp (skin melanoma). The oldest patients (80-89 years) exhibited lower survival across all countries and sites, although with varying improvements over time. INTERPRETATION Nordic cancer patients have generally experienced substantial improvements in cancer survival during the last two decades, including major cancer sites and age groups. Although survival has improved over time, older patients remain at a lower cancer survival compared to younger patients.

Abstract
BACKGROUND In the 1990s, the large-scale collaboration Kreftbildet i Norden (KIN) drew attention to the need for timely cancer statistics for cancer control planning in the Nordic countries. Supported by the Nordic Cancer Union (NCU), a web-based version of NORDCAN was continually developed by the Association of Nordic Cancer Registries (ANCR) from 2003, with website support and hosting by the International Agency for Research on Cancer (IARC). Despite empirical evidence of its global reach, the question of whether recurrent investment in NORDCAN brings added value was raised; we sought to formally assess this. METHODS Scientific value was determined by extracting publications citing NORDCAN from PubMed. We compared the funds allocated to the KIN project and later Nordic studies on cancer predictions and survival, with those allocated to NORDCAN. RESULTS 96 publications in 43 journals were retrieved. Two publication peaks, in 2010 and in 2016 relate to Nordic cancer survival and Danish age care projects, respectively. Papers citing NORDCAN increased substantially from 4 published in 2017 to the 24 papers in 2022. The integration of survival and prediction projects into NORDCAN reduced the costs of investment to one-quarter of the those required in earlier years, in real terms. DISCUSSION User statistics and scientific output clearly points to NORDCAN bringing added value given resources expended, even with the additional costs imposed to ensure GDPR compliance. Research funding indicates that the databases and interactive tools are critical as both research and education resources. Nonetheless, a sustainable funding model is needed if NORDCAN is to continue to fulfill its utility in cancer control, health care planning and cancer research.

Abstract
As sustained development in cancer treatment protocols have led to improved survival in most areas of the world, surveillance is needed to ensure that small populations follow suit. Our study reports age-standardized relative cancer survival in the Faroe Islands compared to the other Nordic countries. We present 1- and 5-year survival estimates and corresponding 95% confidence intervals for the Faroe Islands and compare them with estimates for the Nordic countries. The data for this article has been obtained through the NORDCAN collaboration (2019 data). Age-standardized relative survival was estimated using shared R codes on individual-level data within each country. Ten-year calendar inclusion periods were used in addition to the usual 5-year calendar periods to include cancer sites with few cases, which is especially beneficial to the smaller populations. The primary findings were that 1- and 5-year survival were consistently lower in the Faroes for the summary group all sites but non-melanoma skin cancer for both women and men. Further, 5-year survival was lower for women with ovarian cancer and men with lung cancer than in other Nordic countries. Previously, breast cancer survival was low in the Faroes but has improved to a comparable level over the last few years. Colorectal cancer survival was relatively high for both sexes. The reported estimates in this article call for further research to investigate the cancers with lower survival and should call for actions to improve the survival of Faroese cancer patients.

Abstract
Survival studies are an important indicator of the success of cancer control. We analyzed the 5-year relative survival in 23 solid cancers in Denmark, Finland, Norway and Sweden over a 50-year period (1970-2019) at the NORDCAN database accessed from the International Agency for Research on Cancer website. We plotted survival curves in 5-year periods and showed 5-year periodic survival. The survival results were summarized in four groups: (1) cancers with historically good survival (>50% in 1970-1974) which include melanoma and breast, endometrial and thyroid cancers; (2) cancers which constantly improved survival at least 20% units over the 50 year period, including cancers of the stomach, colon, rectum, kidney, brain and ovary; (3) cancer with increase in survival >20% units with changes taking place in a narrow time window, including oral, oropharyngeal, testicular and prostate cancers; (4) the remaining cancers with <20% unit improvement in survival including lung, esophageal, liver, pancreatic, bladder, soft tissue, penile, cervical and vulvar cancers. For cancers in groups 1 and 2, the constant development implied multiple improvements in therapy, diagnosis and patient care. Cancers in group 3 included testicular cancers with known therapeutic improvements but for the others large incidence changes probably implied that cancer stage (prostate) or etiology (oropharynx) changed into a more tractable form. Group 4 cancers included those with dismal survival 50 years ago but a clear tendency upwards. In 17 cancers 5-year survival reached between 50% and 100% while in only six cancers it remained at below 50%.

Survival in hematological malignancies in the Nordic countries through a half century with correlation to treatment. Leukemia 2023; 37:854-863.

Abstract
Studies of survival in hematological malignancies (HMs) have generally shown an improvement over time, although most of these studies are limited by a short follow-up period. Using the NORDCAN database with data from Denmark, Finland, Norway and Sweden, we follow periodic increases in relative survival in seven HMs through half a century up to 2015-2019. Five-year survival improved in all seven HMs, reaching 90% for Hodgkin lymphoma (HL), myeloproliferative neoplasias and chronic lymphocytic leukemia (CLL), 60% for multiple myeloma (MM) and chronic myeloid leukemias (CMLs), 50% for the myelodysplastic syndromes and 30% for acute myeloid leukemia (AML). Improvements in survival over 50 years ranged from 20% to more than 50% units across the different HMs. The likely reasons for such progress include earlier diagnoses, improved risk stratification and advances in treatment. We observed differing temporal trends in improvements in survival. The gradual increases observed in HL, CLL and AML highlight the impact of optimization of existing therapies and improvements in diagnostics and risk stratification, whereas the rapid increases observed in the CMLs and MM highlight the impact of novel therapies. Recent therapeutic advances may further improve survival in HMs where survival remains low such as in AML.

Abstract
Survival in female breast cancers has generally improved but the relative contribution of early detection or treatment in this positive development is not known. Our aim was to assess the possible role of national mammography screening programs in survival improvement. Such screening has been offered to women, usually at 50-69 years of age, in Finland and Sweden since the 1980s and in Denmark and Norway since the 1990s. Participation rates have been high, ranging from 60% to 90%. We analyzed incidence and mortality changes and relative 5- and 10-year survival trends in breast cancer as novel measures in these countries using the NORDCAN database. Survival trends were compared in age groups of women who were screened to those who were not screened. We observed a relative survival advantage in 5-year and 10-year survival in the screened age groups after the period of national mammography screening was in place and this was consistent in each country. Timing and age-specific targeting of the improvements suggest that mammography may have contributed to the survival benefits. However, as we had no individual data on women who used the service, more detailed studies are needed to confirm the suggested survival advantage, particularly concerning mortality in stage-specific breast cancer.

Abstract
AIMS Global survival studies in cancer have generally shown favourable development, but studies over extended periods on populations for which medical care is essentially free of charge are lacking. METHODS We analyse relative 1- and 5-year survival in all solid cancers in Denmark, Finland, Norway and Sweden through a 50-year period (1970-2019) using the NORDCAN database. RESULTS The most recent survival results showed three types of patterns. Cancers of very good survival (5-year survival ∼90%) included common cancers of the breast and prostate, as well as melanoma. The second pattern, which included the largest number of cancers, showed 1-year survival of over 80% and a drop of 10-20 % units in 5-year survival. The third group consisted of eight fatal cancers, sharing poor 5-year survival (around 20%). The 50-year improvement in 1-year survival was largest (30-50 % units) in kidney, brain, gallbladder and liver cancers, and (∼30%) in colon, small intestinal, lung, pleural, pancreas and ovarian cancers. Improvements in 5-year survival were highest (40-50 % units) in prostate and kidney cancers but remained at 10-20 % units for the eight fatal cancers. Survival showed significant sex preferences for a few cancers. CONCLUSIONS The analysis over a half-century confirms the progress in 'real-world' cancer control, and in 84% of patients 5-year survival was >60%. Metastases remain a challenge, placing the emphasis on early detection before metastasis occurs. Novel therapies, such as immunotherapy which has curative potential even against metastatic disease, are needed.

Abstract
BACKGROUND Survival of patients with colon and rectal cancer has improved in all Nordic countries during the past decades. The aim of this study was to further assess survival trends in patients with colon and rectal cancer in the Nordic countries by age at diagnosis and to present additional survival measures. METHODS Data on colon and rectal cancer cases diagnosed in the Nordic countries between 1990 and 2016 were obtained from the NORDCAN database. Relative survival was estimated using flexible parametric models. Both age-standardized and age-specific measures for women and men were estimated from the models, as well as reference-adjusted crude probabilities of death and life-years lost. RESULTS The five-year age-standardized relative survival of colon and rectal cancer patients continued to improve for women and men in all Nordic countries, from around 50% in 1990 to about 70% at the end of the study period. In general, survival was similar across age and sex. The largest improvement was seen for Danish men and women with rectal cancer, from 41% to 69% and from 43% to 71%, respectively. The age-standardized and reference-adjusted five-year crude probability of death in colon cancer ranged from 30% to 36% across countries, and for rectal cancer from 20% to 33%. The average number of age-standardized and reference-adjusted life-years lost ranged between six and nine years. CONCLUSION There were substantial improvements in colon and rectal cancer survival in all Nordic countries 1990-2016. Of special note is that the previously observed survival disadvantage in Denmark is no longer present.

Abstract
Global survival studies have shown favorable development in most cancers but few studies have considered laryngeal cancer, particularly over extended periods or in populations for which medical care is essentially free of charge. We analyzed laryngeal and lung cancer incidence and survival in Finland (FI) and Sweden (SE) over a 50-year period (1970–2019) using data and statistical tools from the Nordcan database. Laryngeal cancer reached an incidence maximum in FI men in 1965, which in SE men occurred over 10 years later and peaking at 42% of the FI maximum. The FI incidence halved in 20 years while halving of the SE rate took almost twice as long. At maximum the male rate exceeded the female rate 20 times in FI and 10 times in SE. Incidence rates for lung cancer were approximately 10 times higher than those for laryngeal cancer, and they peaked 5 to 10 years after laryngeal cancer in both countries. The female lung cancer rates increased through the follow-up time but laryngeal cancer rates were relatively stable. Relative 1-year survival data for laryngeal cancer remained at around 85% through 50 years, and 5-year survival lagged constantly around 65%. For lung cancer 1-year survival improved and reached about 50% by 2019. Even 5-year survival improved reaching 20 to 30%, except for FI men. Incidence rates for laryngeal and lung cancers have drastically decreased in FI and SE men parallel to reduced smoking prevalence. In females, rates have clearly increased in lung but not in FI laryngeal cancer. This finding warrants further investigations into possible contributing factors, other than smoking. Survival in laryngeal cancer has not improved compared to the positive development in lung cancer. Historical smoking prevalence was unrelated of survival trends. As long-term survival in these cancers remains discouraging, the most efficient way to fight them is to target the main cause and promote non-smoking.

Abstract
Background Colorectal cancer (CRC) incidence in Finland has risen steadily. Given development in cancer treatments in recent decades, disease-specific data on the long-term prognosis of patients may be obsolete. Thus, this study aimed to report 5-year disease-specific survival (DSS) and relative survival based on tumour spread and site among CRC patients diagnosed between 1991 and 2015 in Finland. Material and methods We conducted a population-based registry study among 59 465 CRC patients identified from the Finnish Cancer Registry. Results The 5-year DSS for all CRC patients was 56.7% [95% confidence interval (CI) 56.3–57.1%] for 1991 through 2015. Tumour site-specific survival has improved for the period 2006–2015 versus 1991–2005 for right-sided colon cancer from 54.8% (95% CI 53.8–55.8%) to 59.9% (95% CI 58.7–61.1%), for left-sided colon cancer from 54.1% (95% CI 52.9–55.3%) to 61.0% (95% CI 59.8–62.2%) and for rectal cancer from 53.6% (95% CI 52.2–55.0%) to 62.3% (95% CI 61.3–63.3%). The 5-year relative survival for the period 2006 through 2015 was 93.6% for localised disease (stage I); 84.2% for locally advanced tumour invading adjacent structures (stage II); 68.2% for regional disease with regional lymph node metastases (stage III); and 14.0% for metastatic disease (stage IV). Conclusions This study confirms that survival for CRC has improved in recent decades in Finland, mirroring observations from other Western countries. However, the classification of tumour spread within the Finnish Cancer Registry differs slightly from the TNM classification, thereby limiting the generalisability of these results.

Abstract
Background Cancers of the oral cavity and pharynx encompass a heterogeneous group of cancers for which known risk factors include smoking, alcohol consumption and human papilloma virus (HPV) infection but their influence is site-specific with HPV mainly influencing oropharyngeal cancer. Their incidence and survival rates are not well known over extended periods of time. Patients/methods Data were obtained for Finnish (FI) and Swedish (SE) patients from the Nordcan database recently updated through 2019. Age-adjusted incidence trends (FI from 1953, SE from 1960) and relative survival rates for years 1970 through 2019 were calculated. Results We observed a prominent increase in oral and oropharyngeal cancers in FI and SE men and women but the trend for oral cancer was interrupted for SE men in 1985 and possibly also for FI and SE women in 2015. The trend changes in male and female oral cancer was confirmed in data for Denmark and Norway. Relative survival for these cancers has improved overall but they differed for one cluster of oral, oropharyngeal and nasopharyngeal cancers with 60–70% 5-year survival in the last period and hypopharyngeal cancer with 25% male survival. In all these cancers, survival for old patients was unfavorable. Discussion/conclusion We hypothesize that reduction in smoking prevalence helped to stop the increase in oral cancer especially in men. As the prevalence of smoking is decreasing, HPV is becoming a dominant risk factor, particularly for the increasing oropharyngeal cancer. Prevention needs to emphasize sexual hygiene and HPV vaccination. Supplementary Information The online version contains supplementary material available at 10.1186/s12885-022-09337-2.

Abstract
INTRODUCTION Over the last decades, treatment of breast cancer has become increasingly more effective. Consequently, an increasing number of women are living with late effects of breast cancer treatment, including disfiguring scars, deformity or asymmetry of the breast, secondary lymphoedema and other physical and psychosocial late effects. Data from this study will provide knowledge on how to guide breast reconstruction in the future towards outcomes with fewer complications, higher long-term quality of life (QoL) and satisfaction with the aesthetic outcome. The development of secondary lymphoedema, for which the effect of breast reconstruction has yet to be established, will be thoroughly examined. METHODS AND ANALYSIS Women receiving breast reconstruction (autologous and implant based) at the Department of Plastic Surgery and Burns Treatment, Rigshospitalet, will be invited to participate. The patients will be followed for 10 years postoperatively. Demographic, health-related, oncological characteristics and treatment data will be registered. Validated assessment tools, such as the BREAST-Q and Beck Depression Inventory, will be used to measure an extensive range of clinical outcomes, including QoL, life and aesthetic satisfaction and depression. Arm range of motion will be measured with a goniometer and lymphoedema by bioimpedance spectroscopy, compared with circular arm measurements. ETHICS AND DISSEMINATION This study will be conducted according to the 5th version of the Helsinki Declaration. The regional ethical committee for Capital Region Denmark did not find the study notifiable, according to the law of the committee § 1, part 4. All data will be anonymised before its publication. This study will be conducted according to the Danish data protection regulation and is catalogued and approved by the Capital Region Head of Knowledge Centre. According to the Danish health law § 46, part 2, this study does not need the Danish Patient Safety Authority's approval. The findings of this study will be submitted to international peer-reviewed journals.

Abstract
Objectives Global survival studies have shown favourable development in colon and rectal cancers but few studies have considered extended periods or covered populations for which medical care is essentially free of charge. Design We analysed colon and rectal cancer survival in Finland and Sweden over a 50-year period (1967–2016) using data from the Nordcan database. In addition to the standard 1-year and 5-year survival rates, we calculated the difference between these as a novel measure of how well survival was maintained between years 1 and 5. Results Relative 1-year and 5-year survival rates have developed favourably without major shifts for men and women in both countries. For Finnish men, 1-year survival in colon cancer increased from 50% to 82%, and for rectal cancer from 62% to 85%. The Swedish survival was a few per cent unit better for 1-year survival but for 5-year survival the results were equal. Survival of female patients for both cancers was somewhat better than survival in men through 50 years. Overall the survival gains were higher in the early compared with the late follow-up periods, and were the smallest in the last 10 years. The difference between 1-year and 5-year survival in colon cancer was essentially unchanged over the 50-year period while in rectal cancer there was a large improvement. Conclusions The gradual positive development in survival suggests a contribution by many small improvements rather than single breakthroughs. The improvement in 5-year survival in colon cancer was almost entirely driven by improvement in 1-year survival while in rectal cancer the positive development extended to survival past year 1, probably due to successful curative treatments. The current challenges are to reinvigorate the apparently stalled positive development and to extend them to old patients. For colon cancer, survival gains need to be extended past year 1 of diagnosis.

Abstract
OBJECTIVE The value of a bone biopsy in patients who present with a bone lesion and past medical history of malignancy is uncertain. The objective of this study was to evaluate the outcome of bone biopsies in patients with a history of a malignancy undergoing bone biopsy of a lesion in a regional bone tumour unit. Secondary outcomes include the assessment of survival in the different outcome groups. MATERIALS AND METHODS This was a retrospective study of patients, with a previous malignancy and suspicious bone lesions, who underwent bone biopsy for final diagnosis between March 2010 and September 2019. Results of the biopsy were summarized into 3 groups: confirmed original malignancy, confirmed benign diagnosis, and confirmed new malignancy. Survival analysis of each group was also undertaken. RESULTS A total of 378 patients met the inclusion criteria (mean age 64 years, 216 females (57%)). In 250 cases (66%), the original malignancy was confirmed on the bone biopsy; in 128 cases, an alternative diagnosis was confirmed (benign diagnosis in 69 (18%)), and 59 had a new malignancy (16%). Survival was significantly greater for those in whom a benign diagnosis was confirmed (logrank test p = 0.0100). CONCLUSION This study shows that for patients presenting with a suspicious bone lesion, together with a history of malignancy, in a third of cases, the bone biopsy will confirm an alternative diagnosis of a benign lesion or a new malignancy. Survival of these patients will vary significantly depending on the biopsy outcome.

Abstract
BACKGROUND Differences in cancer survival between the Nordic countries have previously been reported. The aim of this study was to examine whether these differences in outcome remain, based on updated information from five national cancer registers. MATERIALS AND METHODS The data used for the analysis was from the NORDCAN database focusing on nine common cancers diagnosed 1990-2016 in Denmark, Finland, Iceland, Norway and Sweden with maximum follow-up through 2017. Relative survival (RS) was estimated at 1 and 5 years using flexible parametric RS models, and percentage point differences between the earliest and latest years available were calculated. RESULTS A consistent improvement in both 1- and 5-year RS was found for most studied sites across all countries. Previously observed differences between the countries have been attenuated. The improvements were particularly pronounced in Denmark that now has cancer survival similar to the other Nordic countries. CONCLUSION The reasons for the observed improvements in cancer survival are likely multifactorial, including earlier diagnosis, improved treatment options, implementation of national cancer plans, uniform national cancer care guidelines and standardized patient pathways. The previous survival disadvantage in Denmark is no longer present for most sites. Continuous monitoring of cancer survival is of importance to assess the impact of changes in policies and the effectiveness of health care systems.

[PMID: 35310775 PMCID: PMC8899067 DOI: 10.1177/1455072520954333] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2020] [Accepted: 07/27/2020] [Indexed: 11/17/2022] Open
Abstract
Background: Previous studies have indicated that the alcohol consumption among older Danish
individuals has increased during the last three decades of the 20th century. However,
the research is limited and, hence, the aim of the present article is to describe the
trends and peculiarities in the development of the present situation in older people’s
drinking patterns in Denmark. Methods: Data were obtained from the Danish Health and Morbidity Survey (2005) and the Danish
National Health Survey (2010, 2013, and 2017). Data used in this study were collected
via self-administered questionnaires from random samples of the adult (≥ 16 years)
Danish population. Response rates varied between 50.8% (2005) and 59.5% (2010). Drinking
patterns are described using the following indicators: alcohol consumption during the
past 12 months; alcohol consumption at least two days a week; mean number of standard
drinks consumed in a typical week and heavy episodic drinking (at least monthly).
Results are presented as percentages or means. Results: The prevalence of overall 12-month alcohol use in all individuals aged 60 years or
older has slightly increased between 2010 (83.9%) and 2017 (85.2%). On the other hand,
the prevalence of consuming alcohol at least twice a week has overall decreased slightly
between 2010 (54.0%) and 2017 (52.0%) in the same age group. A decrease was also
observed in the mean number of standard drinks consumed in a typical week, from 8.3 in
2010 to 7.0 in 2017. Additionally, the prevalence of consuming at least five standard
drinks on one occasion at least monthly decreased markedly from 24.8% in 2005 to 14.8%
in 2013 (the prevalence remained stable between 2013 and 2017). The trends in prevalence
of various alcohol indicators varied by sex and age. Conclusions: The findings of this study suggest an overall decline in alcohol consumption among
older Danes in the study period. The continuation of this trend will be the subject of
future studies.

Comparing older people’s drinking habits in four Nordic countries: Summary of the thematic issue. NORDIC STUDIES ON ALCOHOL AND DRUGS 2020; 37:434-443. [PMID: 35310771 PMCID: PMC8899063 DOI: 10.1177/1455072520954326] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2020] [Accepted: 07/27/2020] [Indexed: 11/17/2022] Open
Abstract
Aim: The present article summarises status and trends in the 21st
century in older people’s (60–79 years) drinking behaviour in
Denmark, Finland, Norway and Sweden and concludes this thematic
issue. Each country provided a detailed report analysing four
indicators of alcohol use: the prevalence of alcohol consumers,
the prevalence of frequent use, typical amounts of use, and the
prevalence of heavy episodic drinking (HED). The specific aim of
this article is to compare the results of the country
reports. Findings: Older people’s drinking became more common first in Denmark in the
1970s and then in the other countries by the 1980s. Since 2000
the picture is mixed. Denmark showed decreases in drinking
frequency, typically consumed amounts and HED, while in Sweden
upward trends were dominant regarding prevalence of consumers
and frequency of drinking as well as HED. Finland and Norway
displayed both stable indicators except for drinking frequency
and proportion of women consumers where trends increased. In all
four countries, the gender gap diminished with regard to
prevalence and frequency of drinking, but remained stable in
regard to consuming large amounts. In Norway the share of
alcohol consumers among women aged 60–69 years exceeded the
share among men. During the late 2010s, Denmark had the highest
prevalence of alcohol consumers as well as the highest
proportion drinking at a higher frequency. Next in ranking was
Finland, followed by Sweden and Norway. This overall rank
ordering was observed for both men and women. Conclusion: As the populations aged 60 years and older in the Nordic countries
continue to grow, explanations for the drivers and consequences
of changes in older people’s drinking will become an
increasingly relevant topic for future research. Importantly,
people aged 80 years and older should also be included as an
integral part of that research.

Jensen H, Møller H, Vedsted P. Characteristics of customary non-attenders in general practice who are diagnosed with cancer: A cross-sectional study in Denmark. Eur J Cancer Care (Engl) 2019; 28:e13143. [PMID: 31433525 DOI: 10.1111/ecc.13143] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2018] [Revised: 05/22/2019] [Accepted: 08/01/2019] [Indexed: 11/29/2022]
Abstract
OBJECTIVE This study aimed to explore individual and structural factors in patients with cancer and their potential association with customary non-attendance in general practice. MATERIALS AND METHODS We conducted a population-based cross-sectional study of all patients aged 50-89 years who were diagnosed with an incident cancer in 2009-2013 in Denmark. We investigated associations between being a customary non-attender (defined as having no consultations in general practice in the 19-36 months before diagnosis) and selected patient-related factors (demography, socioeconomic status), health-related factors (multimorbidity) and structural factors (urbanisation degree, list size of general practice and use of out-of-hours services) using logistic regression. RESULTS A total of 123,943 cancer patients were included; 11,567 (9.3%) of these were non-attenders. Non-attendance was associated with being more than 70 years of age, being single, having short or long education and being financially affluent. Non-attendance was rarely seen in cancer patients with (multi)morbidity, in individuals living in an area with 2,000-99,999 inhabitants and in individuals having contact with the out-of-hours services. CONCLUSION Specific groups of cancer patients were more often customary non-attenders in general practice. General practice may need to reach out more directly to these patients to ensure more timely cancer diagnosis.

Global surveillance of trends in cancer survival 2000-14 (CONCORD-3): analysis of individual records for 37 513 025 patients diagnosed with one of 18 cancers from 322 population-based registries in 71 countries. Lancet 2018; 391:1023-1075. [PMID: 29395269 PMCID: PMC5879496 DOI: 10.1016/s0140-6736(17)33326-3] [Citation(s) in RCA: 2872] [Impact Index Per Article: 478.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/07/2017] [Revised: 12/05/2017] [Accepted: 12/07/2017] [Indexed: 02/06/2023]
Abstract
BACKGROUND In 2015, the second cycle of the CONCORD programme established global surveillance of cancer survival as a metric of the effectiveness of health systems and to inform global policy on cancer control. CONCORD-3 updates the worldwide surveillance of cancer survival to 2014. METHODS CONCORD-3 includes individual records for 37·5 million patients diagnosed with cancer during the 15-year period 2000-14. Data were provided by 322 population-based cancer registries in 71 countries and territories, 47 of which provided data with 100% population coverage. The study includes 18 cancers or groups of cancers: oesophagus, stomach, colon, rectum, liver, pancreas, lung, breast (women), cervix, ovary, prostate, and melanoma of the skin in adults, and brain tumours, leukaemias, and lymphomas in both adults and children. Standardised quality control procedures were applied; errors were rectified by the registry concerned. We estimated 5-year net survival. Estimates were age-standardised with the International Cancer Survival Standard weights. FINDINGS For most cancers, 5-year net survival remains among the highest in the world in the USA and Canada, in Australia and New Zealand, and in Finland, Iceland, Norway, and Sweden. For many cancers, Denmark is closing the survival gap with the other Nordic countries. Survival trends are generally increasing, even for some of the more lethal cancers: in some countries, survival has increased by up to 5% for cancers of the liver, pancreas, and lung. For women diagnosed during 2010-14, 5-year survival for breast cancer is now 89·5% in Australia and 90·2% in the USA, but international differences remain very wide, with levels as low as 66·1% in India. For gastrointestinal cancers, the highest levels of 5-year survival are seen in southeast Asia: in South Korea for cancers of the stomach (68·9%), colon (71·8%), and rectum (71·1%); in Japan for oesophageal cancer (36·0%); and in Taiwan for liver cancer (27·9%). By contrast, in the same world region, survival is generally lower than elsewhere for melanoma of the skin (59·9% in South Korea, 52·1% in Taiwan, and 49·6% in China), and for both lymphoid malignancies (52·5%, 50·5%, and 38·3%) and myeloid malignancies (45·9%, 33·4%, and 24·8%). For children diagnosed during 2010-14, 5-year survival for acute lymphoblastic leukaemia ranged from 49·8% in Ecuador to 95·2% in Finland. 5-year survival from brain tumours in children is higher than for adults but the global range is very wide (from 28·9% in Brazil to nearly 80% in Sweden and Denmark). INTERPRETATION The CONCORD programme enables timely comparisons of the overall effectiveness of health systems in providing care for 18 cancers that collectively represent 75% of all cancers diagnosed worldwide every year. It contributes to the evidence base for global policy on cancer control. Since 2017, the Organisation for Economic Co-operation and Development has used findings from the CONCORD programme as the official benchmark of cancer survival, among their indicators of the quality of health care in 48 countries worldwide. Governments must recognise population-based cancer registries as key policy tools that can be used to evaluate both the impact of cancer prevention strategies and the effectiveness of health systems for all patients diagnosed with cancer.

Abstract
OBJECTIVE Limited data exist on the changes in the epidemiology of pancreatic cancer and outcomes over the last decades in population-based cohorts. We aimed to compare the incidence of pancreatic cancer, diagnostic, treatment and survival among patients diagnosed over the period 1986-2009. MATERIALS AND METHODS A retrospective, nationwide, population-based study. All patients diagnosed with pancreatic cancer in Iceland in two periods, 1986-1997 (P1) and 1998-2009 (P2) were identified through the Icelandic Cancer Registry and relevant clinical information obtained from medical records. RESULTS A total of 645 patients were identified, 296 in P1 and 349 in P2 (NS). The incidence during P1 was 6.8 per 100,000 inhabitants and 6.2 during P2 (NS). Among biopsy-proven cancers, adenocarcinoma was diagnosed in 89% of the cases in P1 and in P2 in 93% of the cases. Overall 38 (14%) in P1 underwent resection and 22 (7%) in P2 (p < .0004). Patients diagnosed in P2 had longer survival at 6 months (p = .015, log-rank test) and one year (p = .0206) after diagnosis. A total of 4/296 (1.4%) in P1 survived more than 5 years and 3/349 (0.9%) in P2 (NS). CONCLUSIONS The incidence among patients with pancreatic cancer in Iceland did not show major changes during the last 20 years. Diagnostic approach has changed considerably demonstrating more patients that are not 'resectable'. Survival rate at 6 months and one year has improved over the last two decades whereas the 5-year prognosis has not improved.

Abstract
INTRODUCTION During the 1990s, all Nordic countries except for Denmark experienced a general increase in 5-year survival rates for cancer patients. In 2007, the Danish National Board of Health in collaboration with national multidisciplinary cancer groups and the Danish regions initiated fast-track clinical pathway solutions. OBJECTIVES The objectives of this study were 1) to present the setup of the head and neck cancer (HNC) fast-track program at Odense University Hospital (OUH) as an example of the Danish model and 2) to present patient characteristics, diagnostic outcome, cancer detection rate, and duration of the fast-track patient courses. MATERIALS AND METHODS From 1st July 2012 to 1st September 2015, all patients referred to the HNC fast-track program at OUH for diagnostics and treatment were consecutively included in the study resulting in 3165 patient courses. RESULTS The overall malignancy detection rate was 40.6% and for HNC it was 29.2%. The overall median fast-track course duration was 12 days (range 0-74). Overall 2990 (94.5%) of 3165 patients completed their fast-track course within the maximally permitted course duration. DISCUSSION AND CONCLUSION Based on our findings, it was concluded that: 1) a HNC fast-track program build on pre-booked slots for diagnostics and treatment is feasible and can secure acceptable course durations for more than 90% of patient courses, 2) by using private ENT specialists as a 'filter-function', an acceptable detection rate can be achieved.

Abstract
BACKGROUND Cancer Patient Pathways (CPPs) were introduced in 2000-2015 in several European countries, including Denmark, to reduce the time to diagnosis and treatment initiation and ultimately improve patient survival. Yet, the prognostic consequences of implementing CPPs remain unknown for symptomatic cancer patients diagnosed through primary care. We aimed to compare survival and mortality among symptomatic patients diagnosed through a primary care route before, during and after the CPP implementation in Denmark. METHODS Based on data from the Danish Cancer in Primary Care (CaP) Cohort, we compared one- and three-year standardised relative survival (RS) and excess hazard ratios (EHRs) before, during and after CPP implementation for seven types of cancer and all combined (n = 7725) by using life-table estimation and Poisson regression. RS estimates were standardised according to the International Cancer Survival Standard (ICSS) weights. In addition, we compared RS and EHRs for CPP and non-CPP referred patients to consider potential issues of confounding by indication. RESULTS In total, 7725 cases were analysed: 1202 before, 4187 during and 2336 after CPP implementation. For all cancers combined, the RS3years rose from 45% (95% confidence interval (CI): 42;47) before to 54% (95% CI: 52;56) after CPP implementation. The excess mortality was higher before than after CPP implementation (EHR3years before vs. after CPP = 1.35 (95% CI: 1.21;1.51)). When comparing CPP against non-CPP referred patients, we found no statistically significant differences in RS, but we found lower excess mortality among the CPP referred (EHR1year CPP vs. non-CPP = 0.86 (95% CI: 0.73;1.01)). CONCLUSION We found higher relative survival and lower mortality among symptomatic cancer patients diagnosed through primary care after the implementation of CPPs in Denmark. The observed changes in cancer prognosis could be the intended consequences of finding and treating cancer at an early stage, but they may also reflect lead-time bias and selection bias. The finding of a lower excess mortality among CPP referred compared to non-CPP referred patients indicates that CPPs may have improved the cancer prognosis independently.

Abstract
Background Lung cancer is the second most frequent cancer diagnosis in Denmark. Although improved during the last decade, the prognosis of lung cancer is still poor with an overall 5-year survival rate of approximately 12%. Delay in diagnosis and treatment of lung cancer has been suggested as a potential cause of the poor prognosis and as consequence, fast track cancer care pathways were implemented describing maximum acceptable time thresholds from referral to treatment. In Denmark, patients with lung cancer are often transferred between hospitals with diagnostic facilities to hospitals with treatment facilities during the care pathway. We wanted to investigate whether this organizational set-up influenced the time that patients wait for the diagnosis and treatment. Therefore, the objective of this study was to uncover the impact of transfer between hospitals on the delay in the diagnosis and treatment of Non-Small Cell Lung Cancer (NSCLC). Methods We performed a historical prospective cohort study using data from the Danish Lung Cancer Registry (DLCR). All patients diagnosed with primary NSCLC from January 1st 2008 to December 31st 2012 were included. Patients with unresolved pathology and incomplete data on the dates of referral, diagnosis and treatment were excluded. Results A total of 11 273 patients were included for further analyses. Transfer patients waited longer for treatment after the diagnosis, (Hazard ratio (HR) 0.81 (0.68–0.96)) and in total time from referral to treatment (HR 0.84 (0.77–0.92)), than no-transfer patients. Transfer patients had lower odds of being diagnosed (Odds Ratio (OR) 0.82 (0.74–0.94) and treated (OR 0.66 (0.61–0.72) within the acceptable time thresholds described in the care pathway. Conclusion Fast track cancer care pathways were implemented to unify and accelerate the diagnosis and treatment of cancer. We found that the transfer between hospitals during the care pathway might cause delay from diagnosis to treatment as well as in the total time from referral to treatment in patients with Non Small-Cell Lung Cancer. The difference between no-transfer and transfer patients persists after adjusting for known predictors of delay.

Abstract
Introduction Anti-neoplastic treatment is synonymous with an inactive daily life for a substantial number of patients. It remains unclear what is the optimal setting, dosage and combination of exercise and health promoting components that best facilitate patient adherence and symptom management in order to support cardio-respiratory fitness and lifestyle changes in an at-risk population of pre-illness physically inactive cancer patients. Methods Patients with breast or colon cancer referred to adjuvant chemotherapy and by the oncologists pre-screening verified as physically inactive were eligible to enter a randomised three-armed feasibility study comparing a 12-week supervised hospital-based moderate to high intensity exercise intervention or alternate an instructive home-based12-week pedometer intervention, with usual care. Results Using a recommendation based physical activity screening instrument in order to correspond with cardio-respiratory fitness (VO2 peak) proved to be an applicable method to identify pre-illness physically inactive breast and colon cancer patients. The study demonstrated convincing recruitment (67%), safety and intervention adherence among breast cancer patients; while the attendance rate for colon cancer patients was notably lower (33%). VO2-peak declined on average 12% across study groups from baseline to 12 weeks though indices towards sustaining watt performance and reduce fat mass favoured the hospital-based intervention. Pedometer use was well adapted in both breast and colon cancer patients. Conclusions Despite a fair adherence and safety, the current study calls into question whether aerobic exercise, regardless of intensity, is able to increase VO2-peak during texane-based chemotherapy in combination with Neulasta in physically inactive breast cancer patients.

Abstract
AIM This article described a research protocol for a study exploring the lived experiences of patients with operable lung cancer in daily life at 'Four Critical Moments' during the disease and treatment trajectory. BACKGROUND Patients with lung cancer may experience complex problems during the disease and treatment trajectory, and studies conclude this population to be at higher risk in developing emotional distress than other cancer populations. It is required to explore the supportive needs of patients with lung cancer through the treatment trajectory. DESIGN A longitudinal design with a method of multiple data collection. The study is performed at four time points 'Four Critical Moments'. METHODS The study contained three samples. Sample I and sample II explored the expected four critical moments for patients with operable lung cancer within the first 4 months following diagnosis and surgery. Sample III explored the patients' participation and the feasibility of an exercise intervention targeting patients with operable lung cancer. For all three samples, interviews will be performed: (1) 5 days following diagnosis; (2) the day after surgery; (3) 7 weeks; and (4) 4 months following surgery. Data from questionnaires for all three samples will be collected at baseline and 4 months following surgery. DISCUSSION The study will add new perspectives on the lived experiences of patients with lung cancer along the treatment trajectory based on empirical and theoretical findings for both the general lung cancer population and patients participating in an exercise intervention. This will provide a basis for optimizing and developing interventions for patients with lung cancer starting in the surgical context.

Abstract
Introduction. Patients with advanced-stage lung cancer face poor survival and experience co-occurring chronic physical and psychosocial symptoms. Despite several years of research in exercise oncology, few exercise studies have targeted advanced lung cancer patients undergoing chemotherapy. The aim of the present study was to investigate the benefits of a 6-week supervised group exercise intervention and to outline the effect on aerobic capacity, strength, health-related quality of life (HRQoL), anxiety, and depression. Methods. VO2peak was assessed using an incremental exercise test. Muscle strength was measured with one repetition maximum test (1RM). HRQoL, anxiety, and depression were assessed using Functional Assessment of Cancer Therapy–Lung (FACT-L) scale and the Hospital Anxiety and Depression Scale (HADS). Results. One hundred and forthteen patients with advanced stage lung cancer were recruited. Forty-three patients dropped out. No serious adverse events were reported. Exercise adherence in the group training was 68%. Improvements in VO2peak ( P < .001) and 6-minute walk distance ( P < .001) and muscle strength measurements ( P < .05) were seen. There was a reduction in anxiety level ( P = .0007) and improvement in the emotional well-being parameter (FACT-L) but no statistically significant changes in HRQoL were observed. Conclusion. The results of the present study show that during a 6-week hospital-based supervised, structured, and group-based exercise program, patients with advanced-stage lung cancer (NSCLC IIIb-IV, ED-SCLC) improve their physical capacity (VO2peak, 1RM), functional capacity, anxiety level, and emotional well-being, but not their overall HRQoL. A randomized controlled trial testing the intervention including 216 patients is currently being carried out.

Less pitfalls and variation in population based cancer survival comparisons within the European Union: Lessons from colorectal cancer patients in neighbouring regions in Denmark and Germany - The Fehmarn Belt project. Eur J Cancer 2014; 51:1188-98. [PMID: 25483784 DOI: 10.1016/j.ejca.2014.11.006] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2014] [Revised: 11/11/2014] [Accepted: 11/13/2014] [Indexed: 10/24/2022]
Abstract
BACKGROUND International comparisons of cancer registry based survival are often used as a marker of the performance of health care services on cancer. These are debated for comparability, validity and lack of detail with respect to prognostic factors. With a view to cross border collaborative cancer research and care in the European Union (EU), we used the established routine registration systems for cancer in the neighbouring regions Zealand, Denmark, and Schleswig-Holstein, Germany, to study if available routine registration suffices for the study of diagnosis, treatment and follow-up for colorectal cancer patients. The aim was to assess to which extent differences in survival between the regions could be explained. METHODS Colorectal cancer patients recorded 2004-2010 in Schleswig-Holstein (colon: 10,631; rectum 5683) and region Zealand (colon: 3205; rectum 1747) were studied. Excluding cases aged 90+ or only known from death certificates, one- and four-year relative survival by stage for the periods 2004-2006 and 2007-2009 (one-year) were calculated. FINDINGS A high proportion of patients in Schleswig-Holstein were known only from death certificates (colon 11%; rectum 6.9%) compared to <0.3% in region Zealand. Colon cancer incidence (asr-e) (men 36; women 28) and mortality (men 12; women 8.7) in Schleswig-Holstein were 10 per 100,000 lower than in Zealand; minor differences were seen for rectum cancer. One and four-year overall survival increased in both regions but was superior in Schleswig-Holstein. For patients with reported stage I-III, negligible differences in survival were seen; with further restriction to patients with treatment reported, even so in stage IV patients 2007-2009. INTERPRETATION Improved data quality and comparability than presently used in the large international survival studies is needed. If stage and treatment is taken into account, more valid international comparisons of cancer survival are possible. Reporting and follow-up must be improved and cases only known from death certificates (DCO) minimised. A high proportion DCO (excluded from analyses) may produce higher survival, whereas a low the opposite. Co-morbidity and socio-economic status should be included alongside other prognostic variables in survival studies. Barriers towards proper follow-up and monitoring of outcome e.g. privacy legislation must be considered with a view to future patient mobility.

Abstract
Background In this paper, we describe the settings, content, and possibilities of the Danish Cancer in Primary Care (CaP) cohort as well as some of the key findings so far. Further, we describe the future potential of the cohort as an international resource for epidemiological and health services research studies. Methods The CaP cohort comprises information from three Danish subcohorts set up in 2004–2005, 2007–2008, and 2010 on newly diagnosed cancer patients aged 18 years or older. General practitioner (GP)-reported and patient-reported data from six questionnaires generated information on causes and consequences of delayed diagnosis of cancer, and these data were supplemented with complete information on, eg, death, migration, health care utilization, medication use, and socioeconomic data from Denmark’s comprehensive health and administrative registers. The cohort is followed up in terms of emigration, death, hospitalization, medication, and socioeconomics, and data are updated regularly. Results In total, we identified 22,169 verified incident cancer cases. Completed GP questionnaires were returned for 17,566 (79%) of the verified cases, and patient questionnaires were completed by 8,937 (40%) respondents. Patients with participating GPs did not differ from patients with nonparticipating GPs in regard to one-year survival, comorbidity, or educational level. However, compared with nonparticipating GPs, patients listed with participating GPs were more likely to be women, younger, to have a higher disposable income, to have more regional or distant spread of tumors, were also more likely to have breast cancer, and were less likely to have prostate cancer. Responding patients were more likely to be women, aged 45–74 years, and diagnosed with breast cancer or malignant melanoma, and have higher one-year survival rates, more localized tumors, higher educational background, and higher disposable income. Conclusion The cohort is an international resource for epidemiological and health service research, and data are accessible for well defined and approved collaborative studies.

Abstract
Background and purpose Chronic obstructive pulmonary disease (COPD) may increase the risk of postoperative complications and thus mortality after colorectal cancer (CRC) surgery, but the evidence is sparse. Methods We conducted this nationwide population-based cohort study in Denmark, including all patients undergoing CRC surgery in the period 2005–2011, identified through medical databases. We categorised the patients according to the history of COPD. We assessed the rate of complications within 30 days. We computed 30-day mortality among patients with/without COPD using the Kaplan-Meier method. We used Cox regression to compute HRs for death, controlling for age, gender, type of admission, cancer stage, hospital volume, alcohol-related diseases, obesity and Charlson comorbidity score. Results We identified 18 302 CRC surgery patients. Of these, 7.9% had a prior diagnosis of COPD. Among patients with COPD, 16.1% were admitted postoperatively to the intensive care unit, 1.9% were treated with mechanical ventilation, and 3.6% were treated with non-invasive ventilation. In patients without COPD, the corresponding proportions were 9.7%, 1.1% and 1.1%. The reoperation rate was 10.6% among patients with COPD and 8% among patients with cancer without COPD. 30-day mortality was 13% (95% CI 11.4% to 14.9%) among patients with COPD and 5.3% (95% CI 5.0% to 5.7%) among patients without COPD, corresponding to an adjusted HR of 1.7 (95% CI 1.5 to 2.0). Conclusions COPD is a strong predictor for intensive care unit admission and mortality after CRC surgery.

Abstract
BACKGROUND This study aimed at elucidating the effect of family history on the development of subsequent cancers in renal cell carcinoma (RCC) survivors and aimed at assessing whether the interactions between risks of subsequent cancers in RCC survivors and familial risk of subsequent cancer are additive or multiplicative interactions. METHODS A population-based cohort (Swedish Family-Cancer Database) of 14,267 RCC patients diagnosed in 1990-2010 was followed for cancer incidence. Standardised incidence ratios (SIRs) were calculated for subsequent cancers in RCC survivors and in RCC survivors with a family history of subsequent cancer. Familial risk of subsequent cancer was calculated for individuals with family history of specific cancer, compared to those without. RESULTS For subsequent hemangioblastoma (HB) in RCC survivors, drastically elevated risk was observed for the effect of family history of HB [SIR=777 (95% confidence interval (CI): 160-2270)] and of family history of RCC [378 (46-1367)]. Colorectal, lung, prostate and RCCs favoured additive interactions between risk of subsequent cancers in RCC survivors and familial risk, while endocrine glands, nervous system and urinary bladder cancers favoured multiplicative interactions. CONCLUSIONS Risks of subsequent HB in RCC survivors were tremendously modified by family history of RCC or HB, which may resemble characteristics of von Hippel-Lindau syndrome and show the power of present approach to detect heritable cancer clusters. Additive or multiplicative interactions found for colorectal, lung, prostate, endocrine glands, nervous system, urinary bladder and RCCs might raise awareness among clinicians and RCC survivors with a family history of seven cancers about elevated risks of subsequent those cancers.

Abstract
BACKGROUND The purpose of the PROLUCA study is to investigate the efficacy of preoperative and early postoperative rehabilitation in a non-hospital setting in patients with operable lung cancer with special focus on exercise. METHODS Using a 2 x 2 factorial design with continuous effect endpoint (Maximal Oxygen Uptake (VO2peak)), 380 patients with non-small cell lung cancer (NSCLC) stage I-IIIa referred for surgical resection will be randomly assigned to one of four groups: (1) preoperative and early postoperative rehabilitation (starting two weeks after surgery); (2) preoperative and late postoperative rehabilitation (starting six weeks after surgery); (3) early postoperative rehabilitation alone; (4) today's standard care which is postoperative rehabilitation initiated six weeks after surgery. The preoperative rehabilitation program consists of an individually designed, 30-minute home-based exercise program performed daily. The postoperative rehabilitation program consists of a supervised group exercise program comprising cardiovascular and resistance training two-hour weekly for 12 weeks combined with individual counseling. The primary study endpoint is VO2peak and secondary endpoints include: Six-minute walk distance (6MWD), one-repetition-maximum (1RM), pulmonary function, patient-reported outcomes (PROs) on health-related quality of life (HRQoL), symptoms and side effects of the cancer disease and the treatment of the disease, anxiety, depression, wellbeing, lifestyle, hospitalization time, sick leave, work status, postoperative complications (up to 30 days after surgery) and survival. Endpoints will be assessed at baseline, the day before surgery, pre-intervention, post-intervention, six months after surgery and one year after surgery. DISCUSSION The results of the PROLUCA study may potentially contribute to the identification of the optimal perioperative rehabilitation for operable lung cancer patients focusing on exercise initiated immediately after diagnosis and rehabilitation shortly after surgery.

Abstract
BACKGROUND Cancer survival is a key measure of the effectiveness of health-care systems. EUROCARE-the largest cooperative study of population-based cancer survival in Europe-has shown persistent differences between countries for cancer survival, although in general, cancer survival is improving. Major changes in cancer diagnosis, treatment, and rehabilitation occurred in the early 2000s. EUROCARE-5 assesses their effect on cancer survival in 29 European countries. METHODS In this retrospective observational study, we analysed data from 107 cancer registries for more than 10 million patients with cancer diagnosed up to 2007 and followed up to 2008. Uniform quality control procedures were applied to all datasets. For patients diagnosed 2000-07, we calculated 5-year relative survival for 46 cancers weighted by age and country. We also calculated country-specific and age-specific survival for ten common cancers, together with survival differences between time periods (for 1999-2001, 2002-04, and 2005-07). FINDINGS 5-year relative survival generally increased steadily over time for all European regions. The largest increases from 1999-2001 to 2005-07 were for prostate cancer (73.4% [95% CI 72.9-73.9] vs 81.7% [81.3-82.1]), non-Hodgkin lymphoma (53.8% [53.3-54.4] vs 60.4% [60.0-60.9]), and rectal cancer (52.1% [51.6-52.6] vs 57.6% [57.1-58.1]). Survival in eastern Europe was generally low and below the European mean, particularly for cancers with good or intermediate prognosis. Survival was highest for northern, central, and southern Europe. Survival in the UK and Ireland was intermediate for rectal cancer, breast cancer, prostate cancer, skin melanoma, and non-Hodgkin lymphoma, but low for kidney, stomach, ovarian, colon, and lung cancers. Survival for lung cancer in the UK and Ireland was much lower than for other regions for all periods, although results for lung cancer in some regions (central and eastern Europe) might be affected by overestimation. Survival usually decreased with age, although to different degrees depending on region and cancer type. INTERPRETATION The major advances in cancer management that occurred up to 2007 seem to have resulted in improved survival in Europe. Likely explanations of differences in survival between countries include: differences in stage at diagnosis and accessibility to good care, different diagnostic intensity and screening approaches, and differences in cancer biology. Variations in socioeconomic, lifestyle, and general health between populations might also have a role. Further studies are needed to fully interpret these findings and how to remedy disparities.

Abstract
INTRODUCTION Challenges exist in identifying, recruiting and motivating sedentary patients with cancer to initiate physical activity towards recommended levels. We hypothesise that the onset period of adjuvant chemotherapy can be 'the open window of opportunity' to identify and motivate sedentary patients with breast and colon cancers, at risk for developing coronary heart disease, to initiate and sustain lifestyle changes. AIMS To investigate the feasibility of oncologists/nurses screening for physical inactivity, in order to identify and recruit an at-risk population of sedentary patients with breast or colon cancer at the onset of adjuvant chemotherapy. Furthermore, the study will examine the adherence to one of two multimodal exercise interventions lasting 12 weeks; (1) hospital-based, high intensity, group exercise intervention (2) home-based, low intensity, individual, pedometer intervention. Both arms will be compared with a control group. METHODS AND ANALYSES All newly referred patients will be screened for sedentary behaviour, using national recommendations. Testing at baseline, 6, 12 and 39 weeks will include; (1) physiological testing (VO2-peak, one repetition maximum muscle strength and lung function (2) fasting full body dual-energy X-ray absorptiometry scan (3) fasting blood glucose, insulin, lipids and cholesterols, (4) psychometric questionnaires (general well-being, quality of life, anxiety and depression, motivational readiness). The randomised controlled trial feasibility design is selected in order to examine barriers for recruitment, programme adherence, safety aspects and potential efficacy to the interventions during adjuvant chemotherapy.

"EXHALE": exercise as a strategy for rehabilitation in advanced stage lung cancer patients: a randomized clinical trial comparing the effects of 12 weeks supervised exercise intervention versus usual care for advanced stage lung cancer patients. BMC Cancer 2013; 13:477. [PMID: 24124893 PMCID: PMC3816603 DOI: 10.1186/1471-2407-13-477] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2013] [Accepted: 10/03/2013] [Indexed: 12/30/2022] Open
Abstract
Background Lung cancer is the leading cause of cancer death in North America and Western Europe. Patients with lung cancer in general have reduced physical capacity, functional capacity, poor quality of life and increased levels of anxiety and depression. Intervention studies indicate that physical training can address these issues. However, there is a lack of decisive evidence regarding the effect of physical exercise in patients with advanced lung cancer. The aim of this study is to evaluate the effects of a twelve weeks, twice weekly program consisting of: supervised, structured training in a group of advanced lung cancer patients (cardiovascular and strength training, relaxation). Methods/Design A randomized controlled trial will test the effects of the exercise intervention in 216 patients with advanced lung cancer (non-small cell lung cancer (NSCLC) stage IIIb - IV and small cell lung cancer (SCLC) extensive disease (ED)). Primary outcome is maximal oxygen uptake (VO2peak). Secondary outcomes are muscle strength (1RM), functional capacity (6MWD), lung capacity (Fev1) and patient reported outcome (including anxiety, depression (HADS) and quality of life (HRQOL)). Discussion The present randomized controlled study will provide data on the effectiveness of a supervised exercise intervention in patients receiving systemic therapy for advanced lung cancer. It is hoped that the intervention can improve physical capacity and functional level, during rehabilitation of cancer patients with complex symptom burden and help them to maintain independent function for as long as possible.

Abstract
The aim of this study was to validate the measurement properties of the Danish version of the Illness Perception Questionnaire-Revised adapted to measure symptom representations among patients with colorectal cancer symptoms. A total of 488 colorectal cancer patients completed a questionnaire derived from the Illness Perception Questionnaire-Revised to retrospectively assess cognitive and emotional representations of experienced symptoms. A confirmatory factor analysis indicated no good comparative fit with the Illness Perception Questionnaire-Revised. Using exploratory factor analysis, a 7-factor structure was conducted, which fairly supported the Illness Perception Questionnaire-Revised. The modified Illness Perception Questionnaire-Revised is a promising tool for measuring symptom representations among Danish colorectal cancer patients.

A "package solution" fast track program can reduce the diagnostic waiting time in head and neck cancer. Eur Arch Otorhinolaryngol 2013; 271:1163-70. [PMID: 23775302 DOI: 10.1007/s00405-013-2584-z] [Citation(s) in RCA: 30] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2013] [Accepted: 05/31/2013] [Indexed: 10/26/2022]
Abstract
In 2007, a fast track program for patients with suspicion of head and neck cancer (HNC) was introduced in Denmark to reduce unnecessary waiting time. The program was based on so called "package solutions" including pre-booked slots for outpatient evaluation, imaging, and diagnostic surgical procedures. The purpose of this study is to present a model for fast track handling of patients suspicious of cancer in the head and neck region and to evaluate the effect of implementation on the diagnostic work up time. Patients with suspicion of HNC referred to the same university department of ENT Head and Neck Surgery during three comparable time intervals 2006-2007, 2007-2008, and 2011-2012 (groups 1-3) were investigated. We recorded the time from patient referral, to first consultation and final diagnosis. The first interval was before initiation of the "package solution", the second just after the introduction, and the third interval represents the current situation. The median time from referral to first consultation was reduced from eight calendar days in group 1 to only one day in groups 2 and 3 (p < 0.001). The combined median time from referral to the final cancer diagnosis decreased from 24 calendar days in group 1 to 7 and 10 days in groups 2 and 3, respectively (p < 0.005). The hit rate of finding malignancy was 41% in group 1, 49% in group 2, and 43% in group 3 with no difference among the groups (p = 0.13). The frequency of newly diagnosed HNC was 19% in group 1, 21% in group 2, and 17% in group 3 (p = 0.52). A "package solution" including pre-booked slots for diagnostic procedures is feasible and can significantly reduce the waiting time for patients with suspicion of HNC.

Abstract
AIM Platinum agents have shown to be effective in the treatment of colorectal cancer. We assessed whether single nucleotide polymorphisms (SNPs) in GSTP1, ERCC1 Asn118Asn and ERCC2 Lys751Gln might predict the overall survival in patients receiving oxaliplatin-based chemotherapy in a Chinese population. METHODS SNPs of GSTP1, ERCC1 Asn118Asn and ERCC2 Lys751Gln in 335 colorectal cancer patients were assessed using TaqMan nuclease assays. RESULTS At the time of final analysis on Nov. 2011, the median follow-up period was 37.7 months (range from 1 to 60 months). A total of 229 patients died during follow-up. Our study showed GSTP1 Val/Val (HR=0.44, 95% CI=0.18-0.98), ERCC1 C/C (HR=0.20, 95% CI=0.10-0.79) and ERCC2 G/G (HR=0.48, 95% CI=0.19-0.97) to be significantly associated with better survival of colorectal cancer. GSTP1 Val/Val, ERCC1 C/C and ERCC2 G/G were also related to longer survival among patients with colon cancer, with HRs (95% CIs) of 0.41 (0.16-0.91), 0.16 (0.09-0.74) and 0.34 (0.16-0.91), respectively. CONCLUSION GSTP1, GSTP1, ERCC1 Asn118Asn and ERCC2 Lys751Gln genotyping might facilitate tailored oxaliplatin-based chemotherapy for colorectal cancer patients.

Eur J Cancer 2013; 49:2187-98. [PMID: 23453935 DOI: 10.1016/j.ejca.2013.01.025] [Citation(s) in RCA: 171] [Impact Index Per Article: 15.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2012] [Revised: 01/22/2013] [Accepted: 01/24/2013] [Indexed: 10/27/2022]
Abstract
BACKGROUND Early diagnosis is considered a key factor in improving the outcomes in cancer therapy; it remains unclear, however, whether long pre-diagnostic patient pathways influence clinical outcomes negatively. The aim of this study was to assess the association between the length of the diagnostic interval and the five-year mortality for the five most common cancers in Denmark while addressing known biases. METHODS A total of 1128 patients with colorectal, lung, melanoma skin, breast or prostate cancer were included in a prospective, population-based study in a Danish county. The diagnostic interval was defined as the time from the first presentation of symptoms in primary care till the date of diagnosis. Each type of cancer was analysed separately and combined, and all analyses were stratified according to the general practitioner's (GP's) interpretation of the presenting symptoms. We used conditional logistic regression to estimate five-year mortality odds ratios as a function of the diagnostic interval using restricted cubic splines and adjusting for comorbidity, age, sex and type of cancer. RESULTS We found increasing mortality with longer diagnostic intervals among the approximately 40% of the patients who presented in primary care with symptoms suggestive of cancer or any other serious illness. In the same group, very short diagnostic intervals were also associated with increased mortality. Patients presenting with vague symptoms not directly related to cancer or any other serious illness had longer diagnostic intervals and the same survival probability as those who presented with cancer suspicious/serious symptoms. For the former, we found no statistically significant association between the length of the diagnostic interval and mortality. CONCLUSION In full coherence with clinical logic, the healthcare system instigates prompt investigation of seriously ill patients. This likely explains the counter-intuitive findings of high mortality with short diagnostic intervals; but it does not explain the increasing mortality with longer diagnostic intervals. Thus, the study provides further evidence for the hypothesis that the length of the diagnostic interval affects mortality negatively.

Abstract
Background: Period analysis is increasingly used to compute long-term cancer survival, as it provides better prediction of survival of newly diagnosed patients than traditional cohort analysis. However, the patient population to which period survival estimates best pertain to and which should be described in a study is less obvious. Methods: Using Finnish Cancer Registry data on 23 common cancer sites, age-standardized period estimates of 5-, 10-, 15-, and 20-year relative survival were computed for each 2-, 5-, and 10-year calendar period in 1954–2003 and compared with survival estimates for two cohorts by means of mean, mean absolute and mean squared differences: a full cohort of all patients potentially contributing some data to the survival analysis and a restricted cohort of patients diagnosed in the period of interest. Results: In most computations, survival estimates for the full cohorts were on average closer to the period estimates for the majority of cancer sites. For 10-year survival, results were less obvious with respect to the mean difference. However, mean squared and mean absolute differences were smaller for the majority of cancers when using the full cohort. Conclusion: Our results suggest that the full cohort should be described in reports of period survival analysis.

Abstract
BACKGROUND To investigate the prognostic value of several psychosocial factors for long-term survival in cancer patients. MATERIAL AND METHODS Baseline data were gathered in routine radiotherapy practice during 44 months. The analysis is based on 938 patients for whom follow-up data were available. Baseline psychosocial distress, depression, health-related quality of life (HRQOL), and life satisfaction were assessed using Questionnaire on Stress in Cancer Patients (QSC-R23), Self-Rating Depression Scale (SDS), Functional Assessment of Therapy - General (FACT-G) questionnaire, and Questions on Life Satisfaction (FLZ(M)). Patients were followed up for 7 to 10 years. Kaplan-Meier plots and Cox proportional hazards models were used to investigate associations between sociodemographic, clinical, psychosocial factors and overall survival (OS). RESULTS Patients' median survival time was 35 months (95% CI 28.9-41.1). Significant multivariate predictors of OS were age, health insurance type, Karnofsky performance status, cancer site, and cancer stage. Controlling for these variables, HRQOL was the only psychosocial predictor of survival (hazard ratio 0.988, 95% CI 0.979-0.997, p =0.009). The physical well-being and the functional well-being subscales of the FACT-G emerged as the relevant HRQOL facets predictive of survival. CONCLUSION HRQOL has incremental predictive value for long-term survival in cancer patients.

Abstract
BACKGROUND Breast cancer screening in Denmark is organised by the health services in the five regions. Although general practitioners (GPs) are not directly involved in the screening process, they are often the first point of contact to the health care system and thus play an important advisory role. No previous studies, in a health care setting like the Danish system, have investigated the association between GPs' attitudes towards breast cancer screening and women's participation in the screening programme. METHODS Data on women's screening participation was obtained from the regional screening authorities. Data on GPs' attitudes towards breast cancer screening was taken from a previous survey among GPs in the Central Denmark Region. This study included women aged 50-69 years who were registered with a singlehanded GP who had participated in the survey. RESULTS The survey involved 67 singlehanded GPs with a total of 13,288 women on their lists. Five GPs (7%) had a negative attitude towards breast cancer screening. Among registered women, 81% participated in the first screening round. Multivariate analyses revealed that women registered with a GP with a negative attitude towards breast cancer screening were 17% (95% CI: 2-34%) more likely to be non-participants compared with women registered with a GP with a positive attitude towards breast cancer screening. CONCLUSION The GPs' attitudes may influence the participation rate even in a system where GPs are not directly involved in the screening process. However, further studies are needed to investigate this association.
