IMPORTANCE COVID-19 is a life-threatening illness for many patients. Prior studies have established hematologic cancers as a risk factor associated with particularly poor outcomes from COVID-19. To our knowledge, no studies have established a beneficial role for anti-COVID-19 interventions in this at-risk population. Convalescent plasma therapy may benefit immunocompromised individuals with COVID-19, including those with hematologic cancers.OBJECTIVE To evaluate the association of convalescent plasma treatment with 30-day mortality in hospitalized adults with hematologic cancers and COVID-19 from a multi-institutional cohort. DESIGN, SETTING, AND PARTICIPANTSThis retrospective cohort study using data from the COVID-19 and Cancer Consortium registry with propensity score matching evaluated patients with hematologic cancers who were hospitalized for COVID-19. Data were collected between
When the COVID-19 pandemic began, formal frameworks to collect data about affected patients were lacking. The COVID-19 and Cancer Consortium (CCC19) was formed to collect granular data on patients with cancer and COVID-19 at scale and as rapidly as possible. CCC19 has grown from five initial institutions to 125 institutions with >400 collaborators. More than 5,000 cases with complete baseline data have been accrued. Future directions include increased electronic health record integration for direct data ingestion, expansion to additional domestic and international sites, more intentional patient involvement, and granular analyses of still-unanswered questions related to cancer subtypes and treatments.
IMPORTANCEAndrogen deprivation therapy (ADT) has been theorized to decrease the severity of SARS-CoV-2 infection in patients with prostate cancer owing to a potential decrease in the tissuebased expression of the SARS-CoV-2 coreceptor transmembrane protease, serine 2 (TMPRSS2). OBJECTIVE To examine whether ADT is associated with a decreased rate of 30-day mortality from SARS-CoV-2 infection among patients with prostate cancer. DESIGN, SETTING, AND PARTICIPANTS This cohort study analyzed patient data recorded in the COVID-19 and Cancer Consortium registry between March 17, 2020, and February 11, 2021. The consortium maintains a centralized multi-institution registry of patients with a current or past diagnosis of cancer who developed COVID-19. Data were collected and managed using REDCap software hosted at Vanderbilt University Medical Center in Nashville, Tennessee. Initially, 1228patients aged 18 years or older with prostate cancer listed as their primary malignant neoplasm were included; 122 patients with a second malignant neoplasm, insufficient follow-up, or low-quality data were excluded. Propensity matching was performed using the nearest-neighbor method with a 1:3 ratio of treated units to control units, adjusted for age, body mass index, race and ethnicity, Eastern Cooperative Oncology Group performance status score, smoking status, comorbidities (cardiovascular, pulmonary, kidney disease, and diabetes), cancer status, baseline steroid use, COVID-19 treatment, and presence of metastatic disease. EXPOSURES Androgen deprivation therapy use was defined as prior bilateral orchiectomy or pharmacologic ADT administered within the prior 3 months of presentation with COVID-19. MAIN OUTCOMES AND MEASURESThe primary outcome was the rate of all-cause 30-day mortality after COVID-19 diagnosis for patients receiving ADT compared with patients not receiving ADT after propensity matching. RESULTSAfter exclusions, 1106 patients with prostate cancer (before propensity score matching: median age, 73 years [IQR, 65-79 years]; 561 (51%) self-identified as non-Hispanic White) were included for analysis. Of these patients, 477 were included for propensity score matching (169 who received ADT and 308 who did not receive ADT). After propensity matching, there was no significant difference in the primary end point of the rate of all-cause 30-day mortality (OR, 0.77; 95% CI, 0.42-1.42).
Key Points Question Among patients with cancer and COVID-19, do non-Hispanic Black patients have more severe COVID-19 at presentation and worse COVID-19–related outcomes compared with non-Hispanic White patients, after adjusting for demographic and clinical risk factors? Findings In this cohort study of 3506 patients, Black patients with cancer experienced significantly more severe COVID-19 outcomes compared with White patients with cancer, after adjustment for demographic and clinical risk factors. Meaning These findings suggest that, within the framework of structural racism in the US, having cancer and COVID-19 is associated with worse outcomes among Black patients compared with White patients.
LBA1004 Background: CDK 4/6i has demonstrated benefit in progression free survival (PFS) and overall survival (OS) in pts with HR+, HER2- MBC when combined with endocrine therapy (ET). While observational data demonstrate a potential benefit of continuing CDK 4/6i and switching ET at progression, no prospective trials have evaluated this approach. We conducted a phase II, multi-center, randomized, trial to evaluate the efficacy of fulvestrant or exemestane +/- ribociclib in pts with HR+HER2- MBC whose cancer previously progressed on any CDK 4/6i + any ET. Methods: In this investigator-initiated, phase II, double-blind, placebo-controlled trial, men or women with measurable or non-measurable HR+/HER2- MBC whose cancer progressed during CDK 4/6i and ET were randomized 1:1 to fulvestrant or exemestane +/- ribociclib. Pts treated with prior fulvestrant received exemestane as ET in the randomization; if prior exemestane fulvestrant was the ET; if neither, fulvestrant or exemestane was per investigator discretion, though fulvestrant was encouraged. PFS was the primary endpoint, defined as time from randomization to progression of disease or death. A one-sided log-rank test with a sample size of 120 randomized and evaluable pts with a significance level alpha of 2.5%, achieves 80% power to detect an effect size (difference in PFS) of 3 months. Results: Of the 120 randomized evaluable pts, 1 pt was removed due to not taking ET along with ribociclib/placebo. All but 1 pt was female, the median age was 57.0 years, 88 pts (74%) were white, and 21 (17.6%) were Hispanic. For ET, 99 pts received fulvestrant (83%) and 20 pts exemestane (17%). In terms of prior CDK 4/6i, 100 pts previously received palbociclib (84%), 13 pribociclib (11%), 2 abemaciclib (2%), and 4 palbociclib and another CDK 4/6i (3%). There was a statistically significant PFS improvement for pts randomized to fulvestrant or exemestane + ribociclib [median: 5.33 months, 95% CI (Confidence Interval): 3.25–8.12 months] vs. placebo (median: 2.76 months, 95% CI: 2.66–3.25 months): Hazard Ratio (HR) = 0.56 (95% CI: 0.37-0.83), p = 0.004. Similar results were seen in the subset of pts treated with fulvestrant, with a median PFS for those randomized to ribociclib (5.29 months) vs. placebo (2.76 months), HR = 0.59 (95% CI: 0.38-0.91), p = 0.02. At 6 months, 42% were progression-free on the ribociclib arm vs. 24% on placebo. At 12 months, 25% were progression-free on the ribociclib arm vs. 7% on placebo. Additional endpoints will be reported, including overall response rate and safety. Conclusions: In this randomized, placebo-controlled trial, there was a significant PFS benefit for pts with HR+/HER2- MBC to switch ET and receive ribociclib after progression on CDK 4/6i.

IMPORTANCEThe COVID-19 pandemic has had a distinct spatiotemporal pattern in the United States. Patients with cancer are at higher risk of severe complications from COVID-19, but it is not well known whether COVID-19 outcomes in this patient population were associated with geography. OBJECTIVETo quantify spatiotemporal variation in COVID-19 outcomes among patients with cancer. DESIGN, SETTING, AND PARTICIPANTS This registry-based retrospective cohort study included patients with a historical diagnosis of invasive malignant neoplasm and laboratory-confirmed SARS-CoV-2 infection between March and November 2020. Data were collected from cancer care delivery centers in the United States. EXPOSURES Patient residence was categorized into 9 US census divisions. Cancer center characteristics included academic or community classification, rural-urban continuum code (RUCC), and social vulnerability index. MAIN OUTCOMES AND MEASURES The primary outcome was 30-day all-cause mortality. The secondary composite outcome consisted of receipt of mechanical ventilation, intensive care unit admission, and all-cause death. Multilevel mixed-effects models estimated associations of centerlevel and census division-level exposures with outcomes after adjustment for patient-level risk factors and quantified variation in adjusted outcomes across centers, census divisions, and calendar time. RESULTS Data for 4749 patients (median [IQR] age, 66 [56-76] years; 2439 [51.4%] female individuals, 1079 [22.7%] non-Hispanic Black individuals, and 690 [14.5%] Hispanic individuals) were reported from 83 centers in the Northeast (1564 patients [32.9%]), Midwest (1638 [34.5%]), South (894 [18.8%]), and West (653 [13.8%]). After adjustment for patient characteristics, including month of COVID-19 diagnosis, estimated 30-day mortality rates ranged from 5.2% to 26.6% across centers.Patients from centers located in metropolitan areas with population less than 250 000 (RUCC 3) had lower odds of 30-day mortality compared with patients from centers in metropolitan areas with population at least 1 million (RUCC 1) (adjusted odds ratio [aOR], 0.31; 95% CI, 0.11-0.84). The type of center was not significantly associated with primary or secondary outcomes. There were no statistically significant differences in outcome rates across the 9 census divisions, but adjusted (continued)
