Journal Club Podcast in Oncology – Special Considerations in Chronic Lymphocytic Leukemia and Covid-19

Patients with chronic lymphocytic leukemia are typically older, which also makes them more vulnerable to Covid-19. In this Journal Club podcast our faculty look at treatment of CLL patients with Covid-19, specifically BTK-inhibitors and monoclonal anti-CD20 antibodies. John Allan MD, Adam Kittai MD

Acute Immune Signatures and Their Legacies in Severe Acute Respiratory Syndrome Coronavirus-2 Infected Cancer Patients

Sultan Abdul-Jawad, Luca Baù, Thanussuyah Alaguthurai, Adrian C. Hayday, Piers E.M. Patten, Sheeba Irshad

Summary: Given the immune system’s importance for cancer surveillance and treatment, we have investigated how it may be affected by SARS-CoV-2 infection of cancer patients. Across some heterogeneity in tumor type, stage, and treatment, virus-exposed solid cancer patients display a dominant impact of SARS-CoV-2, apparent from the resemblance of their immune signatures to those for COVID-19+ non-cancer patients. This is not the case for hematological malignancies, with virus-exposed patients collectively displaying heterogeneous humoral responses, an exhausted T cell phenotype and a high prevalence of prolonged virus shedding. Furthermore, while recovered solid cancer patients’ immunophenotypes resemble those of non-virus-exposed cancer patients, recovered hematological cancer patients display distinct, lingering immunological legacies. Thus, while solid cancer patients, including those with advanced disease, seem no more at risk of SARS-CoV-2-associated immune dysregulation than the general population, hematological cancer patients show complex immunological consequences of SARS-CoV-2 exposure that might usefully inform their care.

Vaccinations in CLL: implications for COVID-19

Article published in “Blood” on variables to consider when studying the efficacy of COVID-19 vaccine in patients with CLL. IVIG, intravenous immunoglobulin.

Mazyar Shadman, Chaitra Ujjani

In this issue of Blood, Pleyer and colleagues report results from 2 studies assessing differences in the humoral response to 2 different vaccines in patients with chronic lymphocytic leukemia (CLL) on observation or receiving a Bruton tyrosine kinase inhibitor (BTKi).1  Their findings have immediate clinical implications and call for research preparedness as we eagerly anticipate access to vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the near future.

UK Coronavirus Cancer Monitoring Project (UKCCMP), which covered 61 UK centres, suggest that people with blood cancer are overrepresented in the group of people with cancer who tested positive for the virus – meaning they may be more likely to catch COVID-19 than people with other cancer types.

9 November 2020

Senior author Dr Vincent Munster was contacted in April by study co-author Francis Riedo, an infectious diseases expert, about a patient in Kirkland, Washington, who had had several positive PCR tests over a number of weeks.

An immunocompromised leukaemia patient was infected with the SARS-CoV-2 virus for at least 105 days, and was infectious up to 70 days after first testing positive for the virus, while remaining asymptomatic the entire time, US doctors have reported.

The case underlines the importance of immune system reactions to the virus in causing severe illness, the researchers suggest. The weakened immune system led to the patient being infected for a long period without symptoms, they report.

When CLL meets COVID-19

In this issue of Blood, Mato et al report an international, multicenter analysis of 198 patients with chronic lymphocytic leukemia (CLL) and symptomatic COVID-19.1  In this analysis, COVID-19 appears to be more severe in CLL patients than in the general population and, although risk factors are the same as for the general COVID-19 population, the outcome of patients needing admission is poor, with a case fatality rate of 37%. The Mato et al paper is particularly compelling as reports of COVID-19 in specific diseases are needed, particularly in cancer where COVID-19 adds to the physical and emotional distress these patients already suffer. Also, clinicians need guidance on how to advise and manage these patients.

COVID-19 prevalence and mortality in patients with cancer and the effect of primary tumour subtype and patient demographics: a prospective cohort study

Background: Patients with cancer are purported to have poor COVID-19 outcomes. However, cancer is a heterogeneous group of diseases, encompassing a spectrum of tumour subtypes. The aim of this study was to investigate COVID-19 risk according to tumour subtype and patient demographics in patients with cancer in the UK.

Clinical characteristics and risk factors associated with COVID-19 severity in patients with haematological malignancies in Italy: a retrospective, multicentre, cohort study

Prof Francesco Passamonti, MD / Chiara Cattaneo, MD /Prof Luca Arcaini, MD /Riccardo Bruna, MD /Prof Michele Cavo, MD / Francesco Merli, MD et al.

Background: Several small studies on patients with COVID-19 and haematological malignancies are available showing a high mortality in this population. The Italian Hematology Alliance on COVID-19 aimed to collect data from adult patients with haematological malignancies who required hospitalisation for COVID-19.

Interpretation: This study adds to the evidence that patients with haematological malignancies have worse outcomes than both the general population with COVID-19 and patients with haematological malignancies without COVID-19. The high mortality among patients with haematological malignancies hospitalised with COVID-19 highlights the need for aggressive infection prevention strategies, at least until effective vaccination or treatment strategies are available.

KEY POINTS:

  • Both watch and wait and treated CLL patients when admitted for COVID-19 have high mortality rates.
  • Receiving a BTKi for CLL at COVID-19 diagnosis severe enough to require hospitalization did not influence case fatality rate in this study
This ASH paper is the largest multicentre study to date in CLL!

Summary: The initial reports from China show that patients with cancer are over‐represented among individuals who develop severe Covid‐19 after contracting the virus.(4) Patients with haematological malignancies are expected to be at increased risk of adverse outcomes from this viral infection, due being immunosuppressed as a consequence of the underlying cancer, and from the effects of therapy. Our data demonstrate that while patients with haematological cancers have worse outcomes after Covid-19 than the background population, the majority still survive.
