ABSTRACT
Background: Patients (pts) with thoracic cancers have a high rate of hospitalization and death from COVID-19. Smoking has been associated with increased risk for severe COVID-19. However, there is limited data evaluating the impact of smoking recency on COVID-19 severity in pts with cancer. We aimed to characterize the clinical outcomes of COVID-19 based on the recency of smoking in pts with thoracic cancers (TC) and all other cancers (OC). Methods: Adult pts with cancer and lab-confirmed SARS-CoV-2 and smoking history recorded in the CCC19 registry (NCT0435470) were included. Pts were stratified by cancer type (TC or OC) and further stratified into subgroups based on the recency of smoking cessation: current smoker;former smokers who quit < 1 yr. ago;1-5 yr. ago;6-10 yr. ago;quit > 10 yr. ago;and never smoker. 30-day all-cause mortality was the primary endpoint. Secondary endpoints were any hospitalization;hospitalization with supplemental O2;ICU admission;and mechanical ventilation. Results: From January 2020 to December 2021, 752 pts from TC group and 8,291 pts from OC group met the inclusion criteria. 78% of patients in TC group ever smoked compared to 36% patients in the OC group. In both groups, the majority of never-smokers were females (70% and 60% in TC and OC respectively). The burden of smoking and the rate of pulmonary comorbidities (PC) was higher in the TC group (PC 22-69%) compared to OC group (PC 12-26%) across all smoking strata. Overall, 30-day all-cause mortality was 21% and 11% in pts with TC and OC respectively. Former smokers who quit < 1 year ago in TC group had the highest rate of mortality and severe COVID-19 outcomes. However, in the OC group, there was no consistent trend of higher mortality or severe COVID-19 outcomes in specific subgroups based on smoking recency. Conclusions: To our knowledge this is the largest study evaluating the effect of granular phenotypes of smoking recency on COVID-19 outcomes in pts with cancer. Recent smokers who quit < 1 year ago in TC group had the highest rate of mortality and severe COVID-19. Further analysis exploring the factors (e.g., smoking pack years) associated with severe outcomes in this subgroup is planned.
ABSTRACT
Background: Most patients with cancer and COVID-19 will survive the acute illness. The longer-term impacts of COVID-19 on patients with cancer remain incompletely described. Methods: Using COVID-19 and Cancer Consortium registry data thru 12/31/2021, we examined outcomes of long-term COVID-19 survivors with post-acute sequelae of SARS-CoV-2 infection (PASC aka “long COVID”). PASC was defined as having recovered w/ complications or having died w/ ongoing infection 90+ days from original diagnosis;absence of PASC was defined as having fully recovered by 90 days, with 90+ days of follow-up. Patients with SARS-CoV-2 re-infection and records with low quality data were excluded. Results: 858 of 3710 of included patients (23%) met PASC criteria. Median follow-up (IQR) for PASC and recovered patients was 180 (98-217) and 180 (90-180) days, respectively. The PASC group had a higher rate of baseline comorbidities and poor performance status (Table). Cancer types, status, and recent anticancer treatment were similar between the groups. The PASC group experienced a higher illness burden, with more hospitalized (83% vs 48%);requiring ICU (29% vs 6%);requiring mechanical ventilation (17% vs 2%);and experiencing co-infections (19% vs 8%). There were more deaths in the PASC vs recovered group (8% vs 3%), with median (IQR) days to death of 158 (120-272) and 180 (130-228), respectively. Of these, 9% were attributed to COVID-19;15% to both COVID-19 and cancer;15% to cancer;and 23% to other causes. Conversely, no deaths in the recovered group were attributed to COVID-19;57% were attributed to cancer;and 24% to other causes (proximal cause of death unknown/missing in 38% and 19%, respectively). Cancer treatment modification was more common in the recovered group (23% vs 18%). Conclusions: Patients with underlying comorbidities, worse ECOG PS, and more severe acute SARS-CoV-2 infection had higher rates of PASC. These patients suffered more severe complications and incurred worse outcomes. There was an appreciable rate of death in both PASC and non-PASC, with cancer the dominant but not only cause in fully recovered patients. Further study is needed to understand what factors drive PASC, and whether longer-term cancer-specific outcomes will be affected.
ABSTRACT
Background: SARS-CoV-2 is associated with diverse clinical presentations ranging from asymptomatic infection to lethal complications. Small studies have suggested inferior outcomes in patients (pts) on active cancer treatment. This finding was not independently validated in our prior report on 928 pts, which included treatments administered within 4 weeks of COVID-19 diagnosis. Here, we examine outcomes related to systemic cancer treatment within one year of lab-confirmed SARS-CoV-2 infection in an expanded cohort. Method(s): The COVID-19 and Cancer Consortium (CCC19) registry (NCT04354701) was queried for pts ever receiving systemic treatment. Treatment type, cancer type, stage, and COVID-19 outcomes were examined. Pts were stratified by time from last treatment administration: <2 wk, 2-4 wk, 1-3 mo, or 3-12 mo. Standardized incidence ratios (SIR) of mortality by treatment type and timing were calculated. Result(s): As of 31 July 2020, we analyzed 3920 pts;42% received systemic anti-cancer treatment within 12 mo (Table). 159 distinct medications were administered. The highest rate of COVID-19-associated complications were observed in pts treated within 1-3 months prior to COVID-19;all-cause mortality in this group was 26%. 30-day mortality by most recent treatment type was 20% for chemotherapy, 18% for immunotherapy, 17% for chemoradiotherapy, 29% for chemoimmunotherapy, 20% for targeted therapy, and 11% for endocrine therapy. SIR of mortality was highest for chemoimmunotherapy or chemotherapy <2 wks, and lowest for endocrine treatments. A high SIR was also found for targeted agents within 3-12 mo. Pts untreated in the year prior to COVID-19 diagnosis had a mortality of 14%. [Formula presented] Conclusion(s): 30-day mortality was highest amongst cancer pts treated 1-3 months prior to COVID-19 diagnosis and those treated with chemoimmunotherapy. Except for endocrine therapy, mortality for subgroups was numerically higher than in pts untreated within a year prior to COVID-19 diagnosis. Clinical trial identification: NCT04354701.

ABSTRACT
Background: Oncology patients experience more severe disease outcomes from COVID-19 infection than the general population. BCG is a live bovine tuberculosis bacillus with immunotherapeutic effects in urothelial cancers;it is also used as vaccination against Mycobacterium tuberculosis in parts of the world. As BCG vaccination has been associated with broad protection against viral pathogens, BCG exposure through vaccination or intravesical therapy may modulate host immunity and reduce the severity of COVID-19 infection. We report the effect of BCG exposure on COVID-19 severity in oncology patients from the CCC19 registry. Methods: The CCC19 registry (NCT04354701) was used to identify patients with prior BCG exposure. Cohort A received intravesical treatment for bladder carcinoma, and cohort B received prior BCG vaccination. Each cohort was matched 3:1 to non-BCG-exposed controls by age, sex, race, primary cancer type, cancer status, ECOG performance status (PS) and calendar time of COVID-19 infection. The primary endpoint was COVID-19 severity reported on an ordinal scale (uncomplicated, hospitalized, admitted to ICU +/- ventilated, died within 30 days) of patients exposed to prior BCG compared to matched non-exposed controls. 2-sided Wilcoxon ranksum tests were used. Results: As of 6-Feb-2021 we included 124 patients with BCG exposure, 68 patients with bladder carcinoma who had received intravesical BCG (Cohort A), and 64 cancer patients with prior BCG vaccination (Cohort B). Median age was 76 years, IQR 69-83 (Cohort A) and 67 years, IQR 62-74 (Cohort B). Bladder cancer pts were predominately male (78%) vs 55% for Cohort B. Patients with PS 2+ were uncommon, 18% in Cohort A and 16% in Cohort B. COVID-19 illness severity was no different in patients exposed to prior intravesicular BCG (p=0.87). COVID-19 illness severity was no different in patients exposed to prior intradermal BCG vaccination (p=0.60). Conclusions: Despite this being the largest such cohort reported to date, we failed to demonstrate an association of prior BCG exposure with modulation of severity of COVID19 illness. Prospective trials evaluating the protective effect of BCG vaccination are ongoing and will add further insight into the effect of BCG on COVID-19 illness.
ABSTRACT
BACKGROUND: Patients with cancer may be at high risk of adverse outcomes from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We analyzed a cohort of patients with cancer and coronavirus 2019 (COVID-19) reported to the COVID-19 and Cancer Consortium (CCC19) to identify prognostic clinical factors, including laboratory measurements and anticancer therapies. PATIENTS AND METHODS: Patients with active or historical cancer and a laboratory-confirmed SARS-CoV-2 diagnosis recorded between 17 March and 18 November 2020 were included. The primary outcome was COVID-19 severity measured on an ordinal scale (uncomplicated, hospitalized, admitted to intensive care unit, mechanically ventilated, died within 30 days). Multivariable regression models included demographics, cancer status, anticancer therapy and timing, COVID-19-directed therapies, and laboratory measurements (among hospitalized patients). RESULTS: A total of 4966 patients were included (median age 66 years, 51% female, 50% non-Hispanic white); 2872 (58%) were hospitalized and 695 (14%) died; 61% had cancer that was present, diagnosed, or treated within the year prior to COVID-19 diagnosis. Older age, male sex, obesity, cardiovascular and pulmonary comorbidities, renal disease, diabetes mellitus, non-Hispanic black race, Hispanic ethnicity, worse Eastern Cooperative Oncology Group performance status, recent cytotoxic chemotherapy, and hematologic malignancy were associated with higher COVID-19 severity. Among hospitalized patients, low or high absolute lymphocyte count; high absolute neutrophil count; low platelet count; abnormal creatinine; troponin; lactate dehydrogenase; and C-reactive protein were associated with higher COVID-19 severity. Patients diagnosed early in the COVID-19 pandemic (January-April 2020) had worse outcomes than those diagnosed later. Specific anticancer therapies (e.g. R-CHOP, platinum combined with etoposide, and DNA methyltransferase inhibitors) were associated with high 30-day all-cause mortality. CONCLUSIONS: Clinical factors (e.g. older age, hematological malignancy, recent chemotherapy) and laboratory measurements were associated with poor outcomes among patients with cancer and COVID-19. Although further studies are needed, caution may be required in utilizing particular anticancer therapies. CLINICAL TRIAL IDENTIFIER: NCT04354701.
