Abstract Background: COVID-19 has caused great concern for patients with underlying medical conditions. We aimed to determine the prognosis of patients with current or previous cancer with either a PCR-confirmed COVID-19 infection or a probable diagnosis according to chest CT scan.Methods: We conducted a case control study in a referral hospital on confirmed COVID-19 adult patients with and without a history of cancer from February25th to April21st, 2020. Patients were matched according to age, gender, and underlying diseases. Demographic features, clinical and Para clinical data have been extracted from medical records. Multivariable logistic regression was used to estimate odd ratios and 95% confidence intervals of each factor of interest with outcomes. Results: Fifty-three confirmed COVID-19 patients with history of cancer were recruited and compared with 106 non-cancerous COVID-19 patients. Male to female ratio was 1.33 and 45% were older than 65. Dyspnea was significantly associated with an increased rate of mortality in the cancer subgroup (p=0.013). Twenty-six patients (49%) survived among the cancer group while 89 patients (84%) survived in control (p=0.000). Patients with hematologic cancer had 63% mortality while those with solid tumors had 37%. Multivariate analysis showed that cancer, impaired consciousness, tachypnea, tachycardia, leukocytosis and thrombocytopenia were associated with an increased risk of death.Conclusion: Cancer increased mortality rate and hospital stay of COVID-19 patients and remained significant after adjustment of confounders. Compared to solid tumors, hematologic malignancies have been associated with worse consequences and higher mortality. Clinical and Para clinical indicators were not appropriate to predict death.

Abstract Background COVID-19 has caused great concern for patients with underlying medical conditions. We aimed to determine the prognosis of patients with current or previous cancer with either a PCR-confirmed COVID-19 infection or a probable diagnosis according to chest CT scan. Methods We conducted a case control study in a referral hospital on confirmed COVID-19 adult patients with and without a history of cancer from February25th to April21st, 2020. Patients were matched according to age, gender, and underlying diseases including ischemic heart disease (IHD), diabetes mellitus (DM), and hypertension (HTN). Demographic features, clinical data, comorbidities, symptoms, vital signs, laboratory findings, and chest computed tomography (CT) images have been extracted from patients’ medical records. Multivariable logistic regression was used to estimate odd ratios and 95% confidence intervals of each factor of interest with outcomes. Results Fifty-three confirmed COVID-19 patients with history of cancer were recruited and compared with 106 non-cancerous COVID-19 patients as controls. Male to female ratio was 1.33 and 45% were older than 65. Dyspnea and fever were the most common presenting symptoms in our population with 57.86 and 52.83% respectively. Moreover, dyspnea was significantly associated with an increased rate of mortality in the cancer subgroup (p = 0.013). Twenty-six patients (49%) survived among the cancer group while 89 patients (84%) survived in control (p = 0.000). in cancer group, patients with hematologic cancer had 63% mortality while patients with solid tumors had 37%. multivariate analysis model for survival prediction showed that history of cancer, impaired consciousness level, tachypnea, tachycardia, leukocytosis and thrombocytopenia were associated with an increased risk of death. Conclusion In our study, cancer increased the mortality rate and hospital stay of COVID-19 patients and this effect remains significant after adjustment of confounders. Compared to solid tumors, hematologic malignancies have been associated with worse consequences and higher mortality rate. Clinical and para-clinical indicators were not appropriate to predict death in these patients.

10029 Background: The association between family history of cancer (FHC) and outcome remains uncertain. Relapse and survival of children with FHC has not been well studied. Such information would be valuable for prognosis, refining treatment protocols, and long-term follow-up in pediatric patients with FHC. Methods: An historical cohort study of all pediatric patients diagnosed with cancer at Lucile Packard Children's Hospital at Stanford from 1999 - 2002 was performed (n = 363, mean age: 8.4 yrs [0–28 yrs]). FHC among 1st, 2nd and 3rd degree relatives was obtained from the first 10 consecutive encounters in the electronic medical record. Relapse, secondary malignancy, and survival data were also acquired. The relative risks for these endpoints were calculated between patients with FHC among 1st and/or 2nd degree relatives and those with negative FHC. Patients without documented FHC were excluded (n = 100). Results: 108 (41%) newly diagnosed pediatric patients had reported FHC (1st Degree: n = 14 [5%], 2nd Degree: n = 58 [22%], 3rd Degree: n = 36 [14%]). Patients with reported FHC among 1st and/or 2nd degree relatives were at increased relative risk [RR] for relapse (1.96, 95% confidence interval [CI] 1.27–3.02) compared to patients with negative FHC (n = 191). In particular, patients with Hodgkin Disease (HD) and FHC (n = 12) were more likely to relapse (RR 1.79, 95% CI 1.19–2.72) and at increased risk of death (RR 1.72, 95% CI 1.18–2.53), compared to HD with negative FHC (n = 8). Similarly, patients diagnosed with ALL and FHC (n = 22) had increased risk of death (RR 2.25, 95% CI 1.06–4.8) compared to ALL patients with negative FHC (n = 56). For patients diagnosed with any pediatric cancer and positive FHC in 1st degree relative, RR of death was significantly elevated (3.74, 95% CI 1.20–11.70). Conclusions: Pediatric cancer patients with positive FHC among 1st and/or 2nd degree relatives appear to have higher relative risk of relapse compared to those with negative FHC. Additionally, an increased risk of death was associated with HD and ALL patients with positive FHC. Patients with 1st degree relative with malignancy had an increased risk for death compared to those without cancer among 1st degree relatives. These findings may reflect underlying genetic predispositions in children which contribute to outcome. No significant financial relationships to disclose.

Background: This study aims to compare the outcomes of COVID-19-positive disease in patients with a history of cancer to those without. Methods: We retrospectively collected clinical data and outcomes of COVID-19 positive cancer patients treated consecutively in five North London hospitals (cohort A). Outcomes recorded included time interval between most recent anti-cancer treatment and admission, severe outcome [a composite endpoint of intensive care unit (ITU) admission, ventilation and/or death] and mortality. Outcomes were compared with consecutively admitted COVID-19 positive patients, without a history of cancer (cohort B), treated at the primary centre during the same time period (1 March–30 April 2020). Patients were matched for age, gender and comorbidity. Results: The median age in both cohorts was 74 years, with 67% male, and comprised of 30 patients with cancer, and 90 without (1:3 ratio). For cohort B, 579 patients without a history of cancer and consecutively admitted were screened from the primary London hospital, 105 were COVID-19 positive and 90 were matched and included. Excluding cancer, both cohorts had a median of two comorbidities. The odds ratio (OR) for mortality, comparing patients with cancer to those without, was 1.05 [95% confidence interval (CI) 0.4–2.5], and severe outcome (OR 0.89, 95% CI 0.4–2.0) suggesting no increased risk of death or a severe outcome in patients with cancer. Cancer patients who received systemic treatment within 28 days had an OR for mortality of 4.05 (95% CI 0.68–23.95), p = 0.12. On presentation anaemia, hypokalaemia, hypoalbuminaemia and hypoproteinaemia were identified predominantly in cohort A. Median duration of admission was 8 days for cancer patients and 7 days for non-cancer. Conclusion: A diagnosis of cancer does not appear to increase the risk of death or a severe outcome in COVID-19 patients with cancer compared with those without cancer. If a second spike of virus strikes, rational decision making is required to ensure optimal cancer care.

Immunomodulators and biologic agents are effective in treating inflammatory bowel diseases (IBDs), and recent evidence supports their introduction earlier in the disease course. An important concern to both patients and physicians considering immunosuppression (IS) for the treatment of IBD is the potential associated cancer risk. Several important clinical questions deserve attention with respect to IBD therapy and cancer. First, does medical therapy for IBD predispose to developing cancer? Second, in an IBD patient with a history of cancer, does IBD therapy impact cancer recurrence? Third, once cancer develops in an IBD patient, is the cancer outcome different? Finally, in an IBD patient with current cancer, does the cancer therapy affect IBD outcomes? In a recent multicentric study, patients were identified based on a diagnosis of IBD and cancer with subsequent exposure to anti-tumor necrosis factor α (anti-TNFα arm), thiopurines or methotrexate (antimetabolite arm) or without subsequent IS exposure (control arm). Two hundred and fifty-five patients met the inclusion criteria. Prior cancers included 121 solid, 62 gastrointestinal, 55 dermatologic and 17 hematologic malignancies. During the follow-up period, 75 (29.4%) patients developed incident cancer: 36 (14.1%) a new cancer, 33 (12.9%) a recurrent cancer and 6 (2.4%) a new and recurrent cancer. Incident cancer rate per 100 person-years for patients exposed to anti-TNFα, anti-metabolites and controls was 2.6 with 795 person-years of follow-up, 14.8 with 122 person-years of follow-up and 8.52 with 422 person-years of follow-up, respectively. In this series of IBD patients with a history of cancer, exposure to IS following a cancer diagnosis was not associated with an increased risk of incident cancer compared to patients who did not receive these agents. Prospective data are needed to confirm these findings.

6561 Background: COVID-19 has been associated with immune modulation that may predispose infected patients to bacterial, viral, or fungal co-infections. Due to critical illness, > 70% of patients with severe COVID-19 receive empiric antibacterial or antifungal therapy, along with standard anti-COVID-19 treatments. However, the frequency of proven or probable secondary infections is < 10%. To our knowledge, there are no studies evaluating co-infections in patients with cancer and COVID-19, a vulnerable group with multiple risk factors for co-infections. We aim to describe the prevalence of bacterial, viral, and fungal co-infections, identify risk factors for coinfection, and investigate the potential impact of co-infections on mortality, in patients with a history of cancer and COVID-19. Methods: The CCC19 registry (NCT04354701) includes patients with active or prior hematologic or invasive solid malignancies reported across academic and community sites. We captured bacterial, fungal, or viral co-infections diagnosed within ±2 weeks from diagnosis of COVID-19, identified factors associated with an increased risk of having a co-infection, and evaluated the association of co-infections with 30-day all-cause mortality. Results: We examined 6732 patients with a history of cancer and a laboratory-confirmed diagnosis of SARS-CoV-2 reported to CCC19 by 82 sites between March 17, 2020 and February 3, 2021, with complete data on coinfection status. Median age was 65 (interquartile range: 55-75) years with 48% male, 52% non-Hispanic white, 19% non-Hispanic black, and 16% Hispanic. 5448 (81%) had solid tumors and 1466 (22%) had hematologic malignancies. Bacterial infections were reported in 823 patients (12%), including 296 Gram+ and 245 Gram- bacterial events. Documented viral (176 patients, 3%) and fungal (59 patients, 0.9%) co-infections were rare. The risk for co-infections increased with age, and they were more frequent among men, older patients, and those with diabetes, pulmonary or renal comorbid conditions, active progressive cancer, or hematologic malignancies (unadjusted P< 0.01). The frequency of reported co-infections decreased over the study period (divided into quartiles, Mantel-Haenszel P< 0.01). All-cause mortality rates were higher among those with bacterial (24% vs. 10%), viral (22% vs. 12%), and fungal (37% vs. 12%) coinfections compared to those without (unadjusted P< 0.01). Conclusions: The frequency of bacterial infections in patients with cancer and COVID-19 is relatively low. Viral and fungal co-infections are uncommon. Co-infections are associated with higher mortality rates. Several patient and tumor factors can be used for risk stratification and guide early empiric antimicrobial agent selection, which may improve clinical outcomes. These data could inform antimicrobial stewardship interventions in this tenuous patient population.

ObjectiveHistory of cardiovascular diseases (CVDs) may influence the prognosis of patients hospitalised for COVID-19. We investigated whether patients with previous CVD have increased risk of death and major adverse cardiovascular event (MACE) when hospitalised for COVID-19.MethodsWe included 839 patients with COVID-19 hospitalised at the University Hospitals of Geneva. Demographic characteristics, medical history, laboratory values, ECG at admission and medications at admission were collected based on electronic medical records. The primary outcome was a composite of in-hospital mortality or MACE.ResultsMedian age was 67 years, 453 (54%) were males and 277 (33%) had history of CVD. In total, 152 (18%) died and 687 (82%) were discharged, including 72 (9%) who survived a MACE. Patients with previous CVD were more at risk of composite outcomes 141/277 (51%) compared with those without CVD 83/562 (15%) (OR=6.0 (95% CI 4.3 to 8.4), p<0.001). Multivariate analyses showed that history of CVD remained an independent risk factor of in-hospital death or MACE (OR=2.4; (95% CI 1.6 to 3.5)), as did age (OR for a 10-year increase=2.2 (95% CI 1.9 to 2.6)), male gender (OR=1.6 (95% CI 1.1 to 2.3)), chronic obstructive pulmonary disease (OR=2.1 (95% CI 1.0 to 4.2)) and lung infiltration associated with COVID-19 at CT scan (OR=1.9 (95% CI 1.2 to 3.0)). History of CVD (OR=2.9 (95% CI 1.7 to 5)), age (OR=2.5 (95% CI 2.0 to 3.2)), male gender (OR=1.6 (95% CI 0.98 to 2.6)) and elevated C reactive protein (CRP) levels on admission (OR for a 10 mg/L increase=1.1 (95% CI 1.1 to 1.2)) were independent risk factors for mortality.ConclusionHistory of CVD is associated with higher in-hospital mortality and MACE in hospitalised patients with COVID-19. Other factors associated with higher in-hospital mortality are older age, male sex and elevated CRP on admission.

Background: Early cardiology involvement within 90 days of atrial fibrillation (AF) diagnosis is associated with greater likelihood of oral anticoagulant use and a reduced risk of stroke. Due to variation in cardiovascular care for patients with cancer, it is possible that a similar association does not exist for AF patients with cancer. Methods: We examined the association of early cardiology involvement with oral anticoagulation use among non-valvular AF patients with history of cancer (past or active), using data from 388,045 patients (mean age=68±15 years; 59% male) from the MarketScan database (2009-2014). ICD-9 codes in any position were used to identify cancer diagnosis prior to AF diagnosis. Provider specialty and filled anticoagulant prescriptions 3 months prior to and 6 months after AF diagnosis were obtained. Poisson regression models were used to compute the probability of an oral anticoagulant prescription fill and Cox regression was used to estimate the risk of stroke and major bleeding. Results: A total of 64,016 (17%) AF patients had a prior history of cancer. Cardiology involvement was less likely to occur among patients with history of cancer than those without (relative risk=0.92, 95% confidence interval (0.91, 0.93)). Similar differences were observed for cancers of the colon (0.90 (0.88, 0.92)), lung (0.76 (0.74, 0.78)), pancreas (0.74 (0.69, 0.80)), and hematologic system (0.88 (0.87, 0.90)), while no differences were observed for breast or prostate cancers. Patients with cancer were less likely to fill prescriptions for anticoagulants (0.89 (0.88, 0.90)) than those without cancer, and similar results were observed for cancers of the colon, lung, prostate, pancreas, and hematologic system. However, patients with cancer were more likely to fill prescriptions for anticoagulants (1.48 (1.45, 1.52)) if seen by a cardiology provider, regardless of cancer type. A reduced risk of stroke (hazard ratio=0.89 (0.81, 0.99)) was observed among all cancer patients who were seen by a cardiology provider than among those who were not, without an increased risk of bleeding (1.04 (0.95, 1.13)). Conclusion: AF patients with cancer were less likely to see a cardiologist, and less likely to fill an anticoagulant prescription than AF patients without cancer. However, cardiology involvement was associated with increased anticoagulant prescription fills and reduced risk of stroke, suggesting a beneficial role for cardiology providers to improve outcomes in AF patients with history of cancer.

e16095 Background: There has been a definite histopathological shift in esophageal cancer in the West over the past few decades, with adenocarcinoma overtaking squamous cell carcinoma as the commonest type. Asian countries with a high human development index like China have also reported an increased incidence of esophageal adenocarcinoma. Data on the epidemiology of esophageal cancer in India are limited. Methods: We retrospectively evaluated the data of all patients with histologically proven esophageal cancer at Tata Memorial Hospital, from 2003 to 2018. We excluded non-squamous and non-adenocarcinoma histologies. Results: Of a total of 7,874 patients with esophageal cancer, 5,092 (64.7%) were men, for a male to female ratio of 2.5:1. The median age was 57 years (IQR, 50-65); 4,465 (56.7%) were below 60 years old. Of the 4912 patients in whom a history of tobacco or alcohol use had been elicited, there were 1,360 (27.7%) patients with no history of substance use. The site of the primary was the upper third in 906 (12.8%), middle third esophagus in 2,942 (41.5%), lower third in 2,331 (32.8%) and gastroesophageal junction in 917 (12.9%) patients. The predominant histology was squamous cell carcinoma in 6,413 (81.4%) patients and adenocarcinoma in 1461 (18.6%). There was no change in the histologic pattern over the period of the study; squamous cell carcinoma constituted 78.5% of the cases in 2003, and 85.5% in 2018; Chi square test for the year wise trend in histologic patterns was not significant, p=0.143. Evaluation of the histologic subtype according to sex revealed that in the male patients, there were 3890 (76.4%) squamous and 1202 (23.6%) adenocarcinoma cases, while in female patients, there were 2523 (90.7%) squamous and 259 (9.3%) adenocarcinoma cases. On a uni variate analysis, male sex (p<0.001), a history of tobacco or alcohol use (p<0.001), and the presence of comorbidity (p<0.007) were associated with an increased risk of squamous cell carcinoma. Multivariate analysis by logistic regression model revealed that female sex and use of tobacco or alcohol were positively associated with squamous cell carcinoma, while the presence of comorbities and primary in lower esophagus/GEJ were positively associated with adenocarcinoma. Conclusions: Squamous cell carcinoma continues to be the commonest esophageal cancer histologic subtype in over 80% Indian patients. The mid esophagus is the most common site (42%). There is no evidence of an epidemiological shift or an increase in the occurrence of adenocarcinoma or of lower esophageal/GEJ malignancy over the past two decades.

Abstract Background: Although cigarette smoking is a major risk factor for lung cancer, the incidence rate of lung cancer among non-smokers is notable. The etiology and potential mechanism of non-smoker lung cancer are worthy of further research. This study was designed to explore the collective effects of environmental factors and the relationship between environmental exposure index (EEI) and lung cancer among non-smokers by evaluating the joint effects among lung disease history, environmental factors, and family history of lung cancer without smoking confounders.Methods: A total of 767 never-smoked lung cancer cases and 767 sex- and age-matched controls were selected from the department of Thoracic Surgery and Respiratory Medicine of three hospitals in Fujian, China. We used two methods to develop the EEI according to 12 statistically significant environmental risk factors. Restricted cubic spline (RCS) was applied to analyze the non-linear relationship between EEI and lung cancer in non-smokers. Combined effects, additive interaction, and multiplicative interaction were assessed among lung disease history, EEI, and family history of lung cancer to estimate susceptibility to develop lung cancer.Results: Lung disease history, especially asthma, was significantly associated with an increased risk of lung cancer with an odds ratio (OR) for asthma history of 14.720 (95% CI: 1.877–115.449). Family history of lung cancer was related to susceptibility of lung cancer (OR = 3.347, 95% CI: 1.930–5.806). According to type of relatives and cancer, a parental or children’s history and a sibling’s history of lung cancer were significantly associated with an increased risk of lung cancer. The positive association between EEI and lung cancer was apparently stronger in those with lung disease history or family lung cancer history. Furthermore, there was a addictive interaction between EEI and lung disease history, and a possibly addictive interaction between EEI and family lung cancer history on development of lung cancer.Conclusions: There were combined effects among lung disease history, environmental exposures, and family history of lung cancer toward susceptibility to lung cancer in Chinese non-smokers. Non-smokers who had a family history of lung cancer were at higher risk of lung cancer than non-smokers who had lung disease history. Non-smokers with family cancer history may obtain benefits from removal of environmental exposures and active treatment of lung disease.

Background: Patients with cancer are at elevated risk for venous thromboembolism (VTE). Active cancer contributes a 4-7 fold increased risk for VTE; however, the incidence of VTE stratified by subpopulations of patients diagnosed with cancer, especially race/ethnicity, is uncertain. Objective: Describe the incidence of VTE among adult patients (age ≥ 18 years) with a cancer diagnosis in Oklahoma County, OK according to age, gender, race, and cancer type. Methods: In collaboration with the Centers for Disease Control and Prevention, we established a population-based surveillance system for VTE in Oklahoma County, OK between April 1, 2012-March 31, 2014 to estimate the incidences of first-time and recurrent VTE events. The Commissioner of Health made VTE a reportable condition and delegated surveillance-related responsibilities to the University of Oklahoma, College of Public Health. Active surveillance involved reviewing imaging studies (e.g., chest computed tomography and compression ultrasounds of the extremities) from all inpatient and outpatient facilities in the county and collecting demographic, treatment and risk factor data on all VTE case-patients. Patients were linked to the Oklahoma Central Cancer Registry. Any patient with a cancer diagnosis since 1997, excluding basal or squamous cell carcinoma, were included in the population-at-risk. Active cancer was defined as metastatic or a diagnosis ≤6 months before their VTE diagnosis. Poisson regression was used to estimate incidence rates (IRs) and 95% confidence intervals (CIs), which are reported per 1,000 person years (PY). Estimates with &lt;10 events were suppressed. Results: Among all patients aged ≥18 years with a cancer diagnosis since 1997, 1.5% (n = 881) had a VTE event during the 2-year surveillance period. The overall annual age-adjusted incidence of VTE among those with cancer was 6.8 per 1,000 PY (95% CI: 5.81, 7.95). The demographic-specific incidence rates are summarized in Table 1. The VTE incidence did not significantly differ by sex. When stratified by age, annual VTE incidence was similar among those aged 18-39 years (6.1/1,000 PY, 95% CI: 4.35, 8.61), 40-59 years (6.2/1,000 PY, 95% CI: 5.4, 7.14), and 60-79 years (7.2/1,000 PY, 95% CI: 6.55, 7.90), however, the incidence was significantly higher (p&lt;0.05) in those aged 80+ years (10.1/1,000 PY, 95% CI: 8.77, 11.61). When patients with a cancer diagnosis were stratified by race/ethnicity, non-Hispanic blacks had the highest VTE incidence (11.7/1,000 PY, 95% CI: 10.00, 13.59), followed by Hispanics (8.0/1,000 PY, 95% CI: 5.66, 11.44), non-Hispanic whites (6.9/1,000 PY, 95% CI: 6.41, 7.48), other non-Hispanic/unknown (5.8/1,000 PY, 95% CI: 3.45, 9.85), and non-Hispanic Native Americans (2.6/1,000 PY, 95% CI: 1.39, 4.79). VTE incidence was highest among those with active cancer or a history of cancer within the past three years, after which it appeared to decrease. When stratified by primary cancer type, VTE incidence was highest among those with brain cancer (16.6/1,000 PY, 95% CI: 11.06, 25.04) and lowest among those with prostate cancer (5.2/1,000 PY, 95% CI: 4.20, 6.44). As shown in Table 2, when stratified by cancer type, the incidence of VTE was higher (non-overlapping CIs) among those with active cancer compared to those with a history of cancer &gt;6 months for several tumor types. Discussion: The incidence of VTE among those with cancer differs by race/ethnicity, with non-Hispanic blacks bearing the highest burden of disease. The risk of VTE persists and is particularly elevated up to three years after a cancer diagnosis.
