“…Besides a high risk of multiple chronic diseases (Hovaldt et al 2015 ), patients with previous cancer have a high risk of developing new cancers (Ng and Travis 2008 ; Soerjomataram and Coebergh 2009 ). Therefore, high coverage in the screening programme could be even more important in this group.…”

“…previous cancer patients) have a higher risk of new primary cancer (Ng and Travis 2008 ; Soerjomataram and Coebergh 2009 ). They also face the risk of recurrence as well as physical- and psychological late effects from the primary cancer (Harrington et al 2010 ; Hassett et al 2014 ; Hovaldt et al 2015 ). Underuse of secondary prevention has been observed in this group (Earle and Neville 2004 ), but mixed findings have been reported for breast cancer screening behaviour in cancer survivors.…”

PurposeBreast cancer can be detected at early stages through organised screening. This study explored reasons for non-participation in breast cancer screening among previous cancer patients, who have high risk of developing a new primary cancer.MethodWe conducted a population-based historical cohort study, including all women invited to the first organised screening round in 2008–2009 in the Central Denmark Region (n = 149,234). All data were based on national registers.ResultsAmong women with previous cancer (n = 6638), 25.3% did not participate in breast cancer screening compared to 20.9% of women with no registrations of previous cancer, thus previous cancer patients were 21% less likely not to participate in breast cancer screening (PRR 1.21, 95% CI 1.16–1.27). Further analysis showed that this association was due to women receiving current cancer treatment or being in palliative care in the time leading up to screening. Women with previous malignant melanoma or colorectal cancer were more likely to participate in breast cancer screening, whereas women with previous gynaecological or “other” cancer types were less likely to participate.ConclusionScreening for breast cancer may help diagnose breast cancer at an early stage. Women with previous cancer who are not undergoing current treatment or in palliative care have the same propensity to participate as other women invited to breast cancer screening. Women with previous gynaecological cancer were less likely to participate in breast cancer screening than women with other cancer types. These results may only be generalised to similar health care systems.

“…The number of people living after a cancer diagnosis has been consistently increasing in recent years, reaching approximately 5% of the overall population in several countries (De Moor et al, 2013;Guzzinati et al, 2018;Hovaldt et al, 2015;Maddams, Utley, & Møller, 2012). This trend is mainly driven by the increasing number of new cancer diagnoses due to the population ageing and to an improved survival associated with enhanced treatments and early diagnosis.…”

Major patterns of cancer cure: Clinical implications

et al. 2019

View full text Add to dashboard Cite

Introduction This review aimed to classify major patterns of cancer cure and discuss clinical implications. Patterns of cancer cure were identified, in terms of long‐term survival and life expectancy, by means of two recently estimated indicators: cure fraction (CF) and time to cure (TTC). Methods We considered population‐based studies reporting results for some cancer types on CF, defined as the proportion of patients who will reach the same life expectancy of the general population, or/and TTC, the time span necessary to experience a negligible excess mortality. TTC is obtained using conditional relative survival, which indicates the probability of surviving an additional y number of years, given that patients already survived x number of years. Results Four major patterns of cancer types emerged from published studies: (a) cancers with a CF > 60% and a TTC < 5 years (e.g., testicular, thyroid); (b) cancers with a CF between 20% and 50% and a TTC < 10 years (colon, rectum); (c) cancers showing a CF of approximately 50% and TTC > 10 years (breast, prostate and bladder); (d) cancers with a CF < 20% and uncertain TTC (lung or pancreas). Conclusion Clinical and social impact of “cancer cure” categorisation are discussed in details. Recognising a cancer patient as cured represents an opportunity to improve their quality of life.

“…Estimates of cancer prevalence are widely based on limited duration prevalence, including only patients living after a cancer diagnosis made in the previous 5 years [ 1 , 2 ]. Prevalence, regardless of the time since diagnosis (i.e., complete prevalence), is less frequently estimated than limited duration prevalence [ 3 – 9 ]. Overall age-standardized cancer incidence and mortality rates have declined over the past 10 years in the majority of high income countries, whereas the complete prevalence has been consistently increasing in the early 2000s [ 3 , 4 , 6 , 8 , 10 , 11 ].…”

Characteristics of people living in Italy after a cancer diagnosis in 2010 and projections to 2020

BackgroundEstimates of cancer prevalence are widely based on limited duration, often including patients living after a cancer diagnosis made in the previous 5 years and less frequently on complete prevalence (i.e., including all patients regardless of the time elapsed since diagnosis). This study aims to provide estimates of complete cancer prevalence in Italy by sex, age, and time since diagnosis for all cancers combined, and for selected cancer types. Projections were made up to 2020, overall and by time since diagnosis.MethodsData were from 27 Italian population-based cancer registries, covering 32% of the Italian population, able to provide at least 7 years of registration as of December 2009 and follow-up of vital status as of December 2013. The data were used to compute the limited-duration prevalence, in order to estimate the complete prevalence by means of the COMPREV software.ResultsIn 2010, 2,637,975 persons were estimated to live in Italy after a cancer diagnosis, 1.2 million men and 1.4 million women, or 4.6% of the Italian population. A quarter of male prevalent cases had prostate cancer (n = 305,044), while 42% of prevalent women had breast cancer (n = 604,841). More than 1.5 million people (2.7% of Italians) were alive since 5 or more years after diagnosis and 20% since ≥15 years. It is projected that, in 2020 in Italy, there will be 3.6 million prevalent cancer cases (+ 37% vs 2010). The largest 10-year increases are foreseen for prostate (+ 85%) and for thyroid cancers (+ 79%), and for long-term survivors diagnosed since 20 or more years (+ 45%). Among the population aged ≥75 years, 22% will have had a previous cancer diagnosis.ConclusionsThe number of persons living after a cancer diagnosis is estimated to rise of approximately 3% per year in Italy. The availability of detailed estimates and projections of the complete prevalence are intended to help the implementation of guidelines aimed to enhance the long-term follow-up of cancer survivors and to contribute their rehabilitation needs.
