Aims.For nearly a century, the incidence of cancer in people with schizophrenia was lower than in the general population. In the recent decade, the relationship between cancer and schizophrenia has become obscured. Thus, we investigated the cancer risk among young and middle-aged patients with schizophrenia.Methods.Records of newly admitted patients with schizophrenia (n = 32 731) from January 2000 through December 2008 were retrieved from the Psychiatric Inpatient Medical Claims database in Taiwan, and the first psychiatric admission of each patient during the same period was defined as the baseline. We obtained 514 incident cancer cases that were monitored until December 2010. Standardised incidence ratios (SIRs) were calculated to compare the risk of cancer between those with schizophrenia and the general population. Stratified analyses of cancer incidences were performed by gender, site of cancers and duration since baseline (first psychiatric admission).Results.The incidence of cancer for all sites was slightly higher than that of the general population for the period (SIR = 1.15 [95% CI 1.06–1.26], p = 0.001). Men had a significantly higher incidence of colorectal cancer (SIR = 1.48 [95% CI 1.06–2.06], p = 0.019). Women had a higher incidence of breast cancer (SIR = 1.47 [95% CI 1.22–1.78], p < 0.001). Intriguingly, the risk for colorectal cancer was more pronounced 5 years after the first psychiatric admission rather than earlier (SIR = 1.94 [1.36–2.75], p < 0.001) and so was the risk for breast cancer (SIR = 1.85 [1.38–2.48], p < 0.001). The cancer incidence was higher in patients with schizophrenia contradicting the belief that schizophrenia was protective of cancers.Conclusions.Our analyses suggest that men and women with schizophrenia were more vulnerable to certain types of cancers, which indicates the need for gender-specific cancer screening programs. The fact that risk of colorectal cancer was more pronounced 5 years after the first psychiatric admission could imply the impact of unhealthy lifestyles or the possibility of delayed diagnoses.

AimsThe relationship between cancer and schizophrenia requires re-examination. We investigated the cancer risk among young and middle-aged patients with schizophrenia.MethodsRecords of newly admitted patients with schizophrenia (n = 32.731) from January 2000 through December 2008 were retrieved from the Psychiatric Inpatient Medical Claims database in Taiwan, and the first psychiatric admission of each patient during the same period was defined as the baseline. Five hundred and fourteen incident cancer cases were identified and standardized incidence ratios (SIRs) were calculated to compare the risk of cancer between those with schizophrenia and the general population. Stratified analyses of cancer incidences were performed by gender, site of cancers, and duration since baseline.ResultsThe incidence of cancer for all sites was slightly higher than that of the general population for the period (SIR = 1.15 [95% CI 1.06–1.26], P = 001). Men had a significantly higher incidence of colorectal cancer (SIR = 1.48 [95% CI 1.06–2.06], P = 0.019). Women had a higher incidence of breast cancer (SIR = 1.47 [95% CI 1.22–1.78], P < .001). Intriguingly, the risk for colorectal cancer was more pronounced 5 years after the first psychiatric admission rather than earlier (SIR = 1.94 [1.36–2.75], P < .001), and so was the risk for breast cancer (SIR = 1.85 [1.38–2.48], P < .001). The cancer incidence was higher in schizophrenic patients contradicting the belief that schizophrenia was protective of cancers.ConclusionsMen and women with schizophrenia were more vulnerable to certain types of cancers, which indicate the need for gender-specific cancer screening programs.Disclosure of interestThe author has not supplied his declaration of competing interest.

6501 Background: Effective cancer screening leads to a substantial increase in the detection of earlier stages of cancer, while decreasing the incidence of later stage cancer diagnoses. Timely screening programs are critical in reducing cancer-related mortality in both breast and colorectal cancer by detecting tumors at an early, curable stage. The COVID-19 pandemic resulted in the postponement or cancellation of many screening procedures, due to both patient fears of exposures within the healthcare system as well as the cancellation of some elective procedures. We sought to identify how the COVID-19 pandemic has impacted the incidence of early and late stage breast and colorectal cancer diagnoses at our institution. Methods: We examined staging for all patients presenting to UCSD at first presentation for a new diagnosis of malignancy or second opinion in 2019 and 2020. Treating clinicians determined the stage at presentation for all patients using an AJCC staging module (8th edition) in the electronic medical record (Epic). We compared stage distribution at presentation in 2019 vs 2020, both for cancers overall and for colorectal and breast cancer, because these cancers are frequently detected by screening. Results: Total numbers of new patient visits for malignancy were similar in 2019 and 2020 (1894 vs 1915 pts), and stage distribution for all cancer patients was similar (stage I 32% in 2019 vs 29% in 2020; stage IV 26% in both 2019 and 2020). For patients with breast cancer, we saw a lower number of patients presenting with stage I disease (64% in 2019 vs 51% in 2020) and a higher number presenting with stage IV (2% vs 6%). Similar findings were seen in colorectal cancer (stage I: 22% vs 16%; stage IV: 6% vs 18%). Conclusions: Since the COVID-19 pandemic, there has been an increase in incidence of late stage presentation of colorectal and breast cancer, corresponding with a decrease in early stage presentation of these cancers at our institution. Cancer screening is integral to cancer prevention and control, specifically in colorectal and breast cancers which are often detected by screening, and the disruption of screening services has had a significant impact on our patients. We plan to continue following these numbers closely, and will present data from the first half of 2021 as it becomes available.

Abstract Context Acromegaly has been associated with increased risk of cancer morbidity and mortality, but research findings remain conflicting and population-based data are scarce. We therefore examined whether patients with acromegaly are at higher risk of cancer. Design A nationwide cohort study (1978 to 2010) including 529 acromegaly cases was performed. Incident cancer diagnoses and mortality were compared with national rates estimating standardized incidence ratios (SIRs). A meta-analysis of cancer SIRs from 23 studies (including the present one) was performed. Results The cohort study identified 81 cases of cancer after exclusion of cases diagnosed within the first year [SIR 1.1; 95% confidence interval (CI), 0.9 to 1.4]. SIRs were 1.4 (95% CI, 0.7 to 2.6) for colorectal cancer, 1.1 (95% CI, 0.5 to 2.1) for breast cancer, and 1.4 (95% CI, 0.6 to 2.6) for prostate cancer. Whereas overall mortality was elevated in acromegaly (SIR 1.3; 95% CI, 1.1 to 1.6), cancer-specific mortality was not. The meta-analysis yielded an SIR of overall cancer of 1.5 (95% CI, 1.2 to 1.8). SIRs were elevated for colorectal cancer, 2.6 (95% CI, 1.7 to 4.0); thyroid cancer, 9.2 (95% CI, 4.2 to 19.9); breast cancer, 1.6 (1.1 to 2.3); gastric cancer, 2.0 (95% CI, 1.4 to 2.9); and urinary tract cancer, 1.5 (95% CI, 1.0 to 2.3). In general, cancer SIR was higher in single-center studies and in studies with &lt;10 cancer cases. Conclusions Cancer incidence rates were slightly elevated in patients with acromegaly in our study, and this finding was supported by the meta-analysis of 23 studies, although it also suggested the presence of selection bias in some earlier studies.

1566 Background: Coping with the current and future burden of cancer requires an in-depth understanding of cancer incidence and death trends. As of 2020, breast, lung, prostate, and colorectal cancer are the most incident cancers, while lung, colorectal, pancreas, and breast cancer result in the most deaths. Here we integrate observed cancer statistics and trends with observed and estimated US demographic data to project cancer incidences and deaths to the year 2040. Methods: Demographic cancer-specific delay-adjusted incidence and death rates from the Surveillance, Epidemiology, and End Results Program (2014-2016) were combined with US Census Bureau population growth projections (2016) and average annual percentage changes in incidence (2011-2015) and death (2012-2016) rates to project cancer incidences and deaths through the year 2040. We examined the 10 most incident and deadly cancers as of 2020. We utilized Joinpoint analysis to examine changes in incidence and death rates over time relative to changes in screening guidelines. Results: We predict the most incident cancers in 2040 in the US will be breast (322,000 diagnoses in 2040) and lung (182,000 diagnoses in 2040) cancer. Continuing decades long observed incident rate trends we predict that melanoma (173,000 diagnoses in 2040) will become the 3rd most common cancer while prostate cancer (63,000 diagnoses in 2040) will become the 5th most common cancer after colorectal cancer (139,000 diagnoses in 2040). Lung cancer (61,000 deaths in 2040) is predicted to continue to be the leading cause of cancer related death, with pancreas (45,000 deaths in 2040) and liver & intrahepatic bile duct (38,000 deaths in 2040) cancer surpassing colorectal cancer (34,000 deaths in 2040) to become the second and third most common causes of cancer related death, respectively. Breast cancer deaths (29,000 in 2040) are predicted to continue to decrease and become the fifth most common cause of cancer death. Joinpoint analysis of incidence and death rates supports a significant past, present, and future impact of cancer screening programs on the number of cancer diagnoses and deaths, particularly for prostate, thyroid, melanoma incidences, and lung cancer deaths. Conclusions: We demonstrate marked changes in the predicted landscape of cancer incidence and deaths by 2040. Our analysis reveals an influence of cancer screening programs on the number of cancer diagnoses and deaths in future years. These projections are important to guide future research funding allocations, healthcare planning, and health policy efforts.

Purpose CHEK2*1100delC heterozygosity has been associated with increased risk of breast, prostate, and colorectal cancer in case-control studies. We tested the hypothesis that CHEK2*1100delC heterozygosity in the general population increases the risk of cancer in general, and breast, prostate, and colorectal cancer in particular. Patients and Methods We performed a prospective study of 9,231 individuals from the Danish general population, who were observed for 34 years, and we performed a case-control study including 1,101 cases of breast cancer and 4,665 controls. Results Of the general population, 0.5% were heterozygotes and 99.5% were noncarriers. In the prospective study, multifactorially adjusted hazard ratios by CHEK2*1100delC heterozygosity versus noncarriers were 1.2 (95% CI, 0.7 to 2.1) for all cancers, 3.2 (95% CI, 1.0 to 9.9) for breast cancer, 2.3 (95% CI, 0.6 to 9.5) for prostate cancer, and 1.6 (95% CI, 0.4 to 6.5) for colorectal cancer. In the case-control study, age-matched odds ratio for breast cancer by CHEK2*1100delC heterozygosity versus noncarriers was 2.6 (95% CI, 1.3 to 5.4). The absolute 10-year risk of breast cancer in CHEK2*1100delC heterozygotes amounted to 24% in women older than 60 years undergoing hormone replacement therapy, with a body mass index of 25 kg/m2 or higher. Conclusion CHEK2*1100delC heterozygosity is associated with a three-fold risk of breast cancer in women in the general population.

Background Population-based cancer screening can reduce cancer burden but was interrupted temporarily due to the COVID-19 pandemic. We estimated the long-term clinical impact of breast and colorectal cancer screening interruptions in Canada using a validated mathematical model. Methods We used the OncoSim breast and colorectal cancers microsimulation models to explore scenarios of primary screening stops for 3, 6, and 12 months followed by 6–24-month transition periods of reduced screening volumes. For breast cancer, we estimated changes in cancer incidence over time, additional advanced-stage cases diagnosed, and excess cancer deaths in 2020–2029. For colorectal cancer, we estimated changes in cancer incidence over time, undiagnosed advanced adenomas and colorectal cancers in 2020, and lifetime excess cancer incidence and deaths. Results Our simulations projected a surge of cancer cases when screening resumes. For breast cancer screening, a three-month interruption could increase cases diagnosed at advanced stages (310 more) and cancer deaths (110 more) in 2020–2029. A six-month interruption could lead to 670 extra advanced cancers and 250 additional cancer deaths. For colorectal cancers, a six-month suspension of primary screening could increase cancer incidence by 2200 cases with 960 more cancer deaths over the lifetime. Longer interruptions, and reduced volumes when screening resumes, would further increase excess cancer deaths. Conclusions Interruptions in cancer screening will lead to additional cancer deaths, additional advanced cancers diagnosed, and a surge in demand for downstream resources when screening resumes. An effective strategy is needed to minimize potential harm to people who missed their screening.

Abstract Objectives Digital breast tomosynthesis (DBT) increases sensitivity of mammography and is increasingly implemented in breast cancer screening. However, the large volume of images increases the risk of reading errors and reading time. This study aims to investigate whether the accuracy of breast radiologists reading wide-angle DBT increases with the aid of an artificial intelligence (AI) support system. Also, the impact on reading time was assessed and the stand-alone performance of the AI system in the detection of malignancies was compared to the average radiologist. Methods A multi-reader multi-case study was performed with 240 bilateral DBT exams (71 breasts with cancer lesions, 70 breasts with benign findings, 339 normal breasts). Exams were interpreted by 18 radiologists, with and without AI support, providing cancer suspicion scores per breast. Using AI support, radiologists were shown examination-based and region-based cancer likelihood scores. Area under the receiver operating characteristic curve (AUC) and reading time per exam were compared between reading conditions using mixed-models analysis of variance. Results On average, the AUC was higher using AI support (0.863 vs 0.833; p = 0.0025). Using AI support, reading time per DBT exam was reduced (p < 0.001) from 41 (95% CI = 39–42 s) to 36 s (95% CI = 35– 37 s). The AUC of the stand-alone AI system was non-inferior to the AUC of the average radiologist (+0.007, p = 0.8115). Conclusions Radiologists improved their cancer detection and reduced reading time when evaluating DBT examinations using an AI reading support system. Key Points • Radiologists improved their cancer detection accuracy in digital breast tomosynthesis (DBT) when using an AI system for support, while simultaneously reducing reading time. • The stand-alone breast cancer detection performance of an AI system is non-inferior to the average performance of radiologists for reading digital breast tomosynthesis exams. • The use of an AI support system could make advanced and more reliable imaging techniques more accessible and could allow for more cost-effective breast screening programs with DBT.

Uruguay has the highest colorectal cancer incidence rates in Latin America. Previous studies reported a stable incidence and a slight increase in mortality among males. We aimed to assess colorectal cancer incidence (2002–2017) and mortality trends (1990–2017) by age groups and sex, using data from the National Cancer Registry. Annual percent changes (APCs) were estimated using joinpoint regression models. We included 27,561 colorectal cancer cases and 25,403 deaths. We found an increasing incidence among both males and females aged 40–49, with annual increases of 3.1% (95%CI: 1.21–5.03) and 2.1% (95%CI: 0.49–3.66), respectively, and an increasein the rate in older males (70+) of 0.60% (95%CI: 0.02–1.20) per year between 2002 and 2017. Mortality remained stable among those younger than 50, whereas it decreased for older females aged 50–69 and 70+ (APC: −0.61% (−1.07–0.14) and −0.68% (−1.02–0.34), respectively), and increased for the oldest males (70+; APC: 0.74 (0.47–1.01)). In conclusion, we found rising colorectal cancer incidence accompanied by stable mortality in young adults. Sex disparities were also found among the older adults, with a more favorable pattern for females. Exposures to dietary and lifestyle risk factors, and inequalities in access to and awareness of screening programs, are probably among the main underlying causes and deserve further investigation.
