The Impact

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.

The Impact

3531 Background: Population-based screening for colorectal cancer (CRC) aims to decrease incidence and mortality due to precancerous polyp removal, early detection and early treatment of CRC. In the Netherlands, phased introduction of a biennial fecal immunochemical hemoglobin test started in 2014 for individuals aged 55-75. This evaluation of the national data focuses on the initial effect of CRC screening on incidence and stage distribution and the impact on stage IV disease. Methods: All CRC patients diagnosed in the Netherlands between 2009 and 2018 were selected from the Netherlands Cancer Registry (NCR). Patients were linked to the Dutch national pathology registry (PALGA) to identify screen-detected tumors. Results: The NCR identified 137,717 CRC patients between 2009 and 2018. The incidence within screening age (55-75 yr) of all CRC stages showed an initial peak after introduction of screening in 2014, followed by a continuous decrease for all stages. CRC incidence outside the screening age did not show these explicit changes between 2009 and 2018. In 2018, the incidence of stage IV CRC within screening age was lower than the level at the start of the screening program. Stage distribution within screening age shifted towards earlier stages in the screening period (2014-2018) compared to the period before screening (2009-2012) (stage I: 31% vs. 18%, stage II: 22% vs. 26%, stage III: 29% vs. 31%, Stage IV: 18% vs. 25%, respectively). In the period 2014-2018 and within screening age, the ratio of screen-detected and symptom-detected tumors was highest in stage I (47%:53%) and lowest in stage IV (9%:91%). Screen-detected compared to symptom-detected stage IV patients diagnosed in the period 2014-2018 and within screening age had more frequently single organ metastases (74.5% vs 57.4%, p < 0.001), higher resection rate of the primary tumor (57.5% vs. 41.3%; p < 0.001) and higher local treatment rate of metastases (40.0% vs. 23.4% p < 0.001). The median overall survival of screen-detected stage IV patients was significantly longer than that of symptom-detected stage IV patients (31.0 months (95% CI: 27.7 – 34.3) vs. 15.0 months (95% CI: 14.5 – 15.5), p < 0.001). Conclusions: The initial results of the introduction of CRC screening in the Netherlands showed a favorable trend on CRC incidence and stage distribution. Screen-detected patients with stage IV disease had less extensive disease, resulting in better treatment options and improved survival.

3557 Background: Mismatch repair deficient/microsatellite instability high (dMMR/MSI-H) colorectal cancer (CRC) defines a molecular subtype with distinct clinicopathologic characteristics including an excellent response to immunotherapy. Although BRAF mutations are established as a negative prognostic marker in CRC, whether they retain their negative prognostic impact in or alter the response to immunotherapy in dMMR/MSI-H CRC remains unknown. Herein, we present a systematic review and meta-analysis of the impact of BRAF mutations on the overall survival (OS) and immune checkpoint inhibitor (ICI) response in dMMR/MSI-H CRC. Methods: Studies published from inception to 26 January 2021 were searched in PubMed, Embase, and major conference proceedings (AACR, ASCO, and ESMO). Eligible studies included the following: 1) observational studies reporting outcomes based on BRAF mutation status in dMMR/MSI-H CRC patients and 2) experimental studies of ICI reporting outcomes based on BRAF mutation status in dMMR/MSI-H CRC patients. A summary hazard ratio (HR) was calculated for OS in BRAF mutated ( BRAFmut) vs. BRAF wild type ( BRAFwt) patients (pts) with the random effects meta-analysis (REM). A summary odds ratio (OR) was calculated for objective response rate (ORR) in BRAFmut vs. BRAFwt pts treated with ICI with the REM. Results: Database search conducted according to PRISMA guidelines found 4221 studies in total. Initial screening identified 30 studies and after full-text review, 9 studies (N = 4158 pts) were included for the meta-analysis of prognosis (analysis A) and 3 studies (N = 178 pts) were included for the meta-analysis of ICI response (analysis B). The outcome measures are summarized in the table below. Analysis A showed that in stage I-IV dMMR/MSI-H CRC pts, BRAFmut was associated with worse OS than BRAFwt (HR 1.57, 1.23-1.99). The heterogeneity was low (I2 = 21%). Subgroup analysis showed no significant difference in the prognostic impact of BRAF mutation status between stage IV only and stage I-IV CRC pts. Analysis B showed no difference in ORR (OR 1.04, 0.48-2.25) between BRAFmut vs. BRAFwt dMMR/MSI-H pts who received ICI. The heterogeneity was low (I2 = 0%). Conclusions: BRAF mutations retain their negative prognostic impact in dMMR/MSI-H stage I-IV and stage IV CRC but are not associated with differential ICI response. Limitations include the following: analysis A was based on retrospective studies; also, the impact of BRAF status on the survival outcome of ICI could not be assessed due to limited number of studies.[Table: see text]

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.

e16145 Background: Colorectal cancer (CRC) is the second leading cancer worldwide in terms of incidence, 5-year prevalence and mortality for both women and men ages 45 years old and up. The current screening method for many countries with organized screening programs is the FIT test for fecal occult blood; however, this test can result in false positive rates as high as 65%. A FIT reflex test could reduce unnecessary colonoscopies while reducing wait times for those patients that need confirmatory colonoscopies the most. Methods: Danish FIT positive colonoscopy confirmed serum samples (n = 1,499) were divided into training and validation sets maintaining approximately equivalent percentages of clean colonoscopy (40%), low risk adenomas (16%), medium risk adenomas (19%), high risk adenomas (13%), stage I CRC (5%), stage II CRC (2%), stage III CRC (4%), and stage IV CRC (0.5%). Proteins were quantified by custom 16-plex immunoassays utilizing the Luminex xMAP platform. A support vector machine supervised machine learning algorithm was trained with the 16 biomarkers plus age and FIT concentration using 1,291 samples for the outcome medium risk adenoma, high risk adenoma, and CRC. Then this algorithm was tested on a blind 208 sample validation set. Results: The training set was 90% sensitive and 27% specific (AUC = 0.68) and the validation set was 93% sensitive and 21% specific (AUC = 0.63). The sensitivities of the validation by risk/stage was as follows: medium risk adenoma 91%, high risk adenomas 92%, stage I CRC 100%, stage II CRC 100%, stage III CRC 100%, stage IV CRC 93%. Conclusions: This study demonstrates feasibility of a novel blood-based multiplex protein immunoassay for use as a reflex to FIT positive results in population wide screening. It detected nearly all adenomas and carcinomas while reducing FIT false positives and thus unnecessary colonoscopies by more than 20%. A FIT reflex test could alleviate endoscopy burden experienced in countries with organized cancer screening programs, while providing better patient outcomes by detecting polyps and early-stage CRC with high sensitivity.

Background: Colorectal cancer (CRC) is an important and challenging public health problem which successful treatment depends on the early detection of the disease. Recently, colorectal cancer specific microbiome signatures have been proposed as an additional marker for CRC detection. A desirable aim would be the possibility to analyze microbiome from the fecal samples collected during CRC screening programs into FIT tubes for fecal occult blood testing. Methods: We investigated the impact of Fecal Immunohistochemical Test (FIT) and stabilization buffer on the microbial community structure in stool samples from 30 volunteers and compared their communities to fresh-frozen samples highlighting also the previously published cancer-specific communities. Altogether 214 samples were analyzed including positive and negative controls using 16S rRNA gene sequencing. Results: The variation between individuals is greater than differences introduced by collection strategy. The vast majority of the genera are stable up to 7 days. None of the changes observed between fresh frozen samples and FIT tubes are related to previously shown colorectal cancer specific bacteria. Conclusions: Overall, our results show that FIT tubes can be used for profiling the gut microbiota in colorectal cancer screening programs as the community is similar to fresh frozen samples and stable at least for 7 days. Impact: Sample material from FIT tubes could be used in addition to fecal immunochemical tests for future investigations into the role of gut microbiota in colorectal cancer screening programs circumventing the need to collect additional samples and possibly improving the sensitivity of FIT.

e14146 Background: The use of K-ras testing in clinical decision-making has grown over the past few years. The objective of this study was to evaluate, in a real world context, the trends and diagnostic findings of K-ras testing using managed care and EMR data. Methods: The Georgia Cancer Specialists Database EMR (2005-2010) and administrative data from the MarketScan and IMPACT database(s) was used to select patients with newly diagnosed colorectal cancer (CRC). We looked for trends in use of K-ras in relation to timing of chemotherapy administration. The EMR data provided information on k-ras mutation type. Results: In MarketScan, of the 23,548 patients with a diagnosis of CRC, 1,730 (7.3%) patients had a test ordered for K-ras between 2005 and 2010. The number of patients receiving K-ras increased with line of therapy: first line 336 patients (8.2%) of 4,098 treated, second line 455 patients (15.2%) of 2,984 treated, and third line 529 patients (33%) of 1,603 treated. We found similar results using the IMPACT database: 2,256 (7.8%) CRC patients had a test ordered for K-ras between 2005 and 2010. K-ras testing increased with line of therapy: first line 244 patients (7.8%), second line 510 (14.6%), and third line 650 patients (33.1%). EMR lab results from stage IV disease (n=349) consisted of 15% mutated type, 60% unknown and 25% wild type. For confirmed test results wild type represented 62.5% and mutated type 37.5%. Conclusions: Over the last six years, use of K-ras testing has increased in use in patients with CRC. The increase has occurred in later lines of therapy. The timing occurring late in therapy may limit the use of agents specific for this test.

PURPOSE While there are studies under way to characterize the direct effects of the COVID-19 pandemic on the care of patients with cancer, there have been few quantitative reports of the impact that efforts to control the pandemic have had on the normal course of cancer diagnosis and treatment encounters. METHODS We used the TriNetX platform to analyze 20 health care institutions that have relevant, up-to-date encounter data. Using this COVID and Cancer Research Network (CCRN), we compared cancer cohorts identified by querying encounter data pre-COVID (January 2019-April 2019) and current (January 2020-April 2020). Cohorts were generated for all patients with neoplasms (malignant, benign, in situ, and of unspecified behavior), with new incidence neoplasms (first encounter), with exclusively malignant neoplasms, and with new incidence malignant neoplasms. Data from a UK institution were similarly analyzed. Additional analyses were performed on patients with selected cancers, as well as on those having had cancer screening. RESULTS Clear trends were identified that suggest a significant decline in all current cohorts explored, with April 2020 displaying the largest decrease in the number of patients with cancer having encounters. Of the cancer types analyzed, lung, colorectal, and hematologic cancer cohorts exhibited smaller decreases in size in April 2020 versus 2019 (−39.1%, −39.9%, −39.1%, respectively) compared with cohort size decreases for breast cancer, prostate cancer, and melanoma (−47.7%, −49.1%, −51.8%, respectively). In addition, cancer screenings declined drastically, with breast cancer screenings dropping by −89.2% and colorectal cancer screenings by −84.5%. CONCLUSION Trends seen in the CCRN clearly suggest a significant decrease in all cancer-related patient encounters as a result of the pandemic. The steep decreases in cancer screening and patients with a new incidence of cancer suggest the possibility of a future increase in patients with later-stage cancer being seen initially as well as an increased demand for cancer screening procedures as delayed tests are rescheduled.

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.

1568 Background: The EDIFICE survey program started in 2005 and was aimed at providing a better understanding of the participation of the French population in cancer screening programs and assess the evolution over time. The EDIFICE 3 survey was conducted in 2011, following EDIFICE 1 (2005) and EDIFICE 2 (2008), and focused on colorectal, breast and prostate cancer. Methods: This third nationwide observational study, EDIFICE 3, was conducted by phone interviews among a representative sample of 1603 subjects aged between 40 and 75 years, using the quota method. The analysis focused on the target population of the national screening programs for breast and colorectal cancer (50-74 years). The same population was analysed for prostate cancer screening behaviours. Results: For breast cancer, the rate of women attending at least one screening test was 93%/94%/95% in 2005/2008/2011 respectively. A mammography had been performed as recommended within the last two years for 75%/83%/83% among them. We observed an increase in timing compliance between 2005 and 2011, significant for women aged 65-74. For colorectal cancer, the rate of subjects attending at least one screening test was 25%/38%/59%. A fecal test or colonoscopy had been performed according to the recommended timing for NA/30%/51% among them. Colorectal cancer screening has increased significantly in all age groups, especially between 65 and 69 years, and for both genders. For prostate cancer, the rate of men having performed at least one screening test (PSA and/or rectal examination) was 36%/49%/50%.This rate have significantly decreased in men aged 50-59 between 2008 and 2011(44% vs 37%, p<0.05). Conclusions: For National Programs, the attendance rate remains high for breast cancer screening and is improving for colorectal cancer screening. However, the European guideline objective rate of participation for colorectal cancer screening has not yet been reached. Despite the absence of recommendations, prostate cancer screening is frequently carried out and stable overall.
