Clinical Trial Summary
The current study primarily aims to determine the status of vaccination in enrolled cancer
patients and identify barriers to coronavirus disease 2019 (COVID-19) vaccination in cancer
patients who have not been vaccinated. Secondary objectives include determining the rate of
vaccination in those who have ever been COVID-19 positive and those who have never been
COVID-19 positive. The study team also seeks to determine factors associated with
vaccine-acceptance and vaccine-hesitancy in the adult cancer population, identify side
effects of COVID-19 vaccines in vaccinated cancer patients and to examine the effect of
COVID-19 vaccination on overall clinical outcome in cancer patients. The study team will be
conducting telephone interviews/surveys with up to130 adult cancer patients for data
collection.
Description:
Currently, there is a void in literature regarding the rates of coronavirus disease 2019
(COVID-19) vaccination in cancer patients. The investigators aim to address this question by
elucidating rates of vaccination in the general Penn State Cancer Institute (PSCI) patient
population as well as patients from the COVID-19 and Cancer Consortium (CCC-19) who are known
to have had previous COVID-19 infection. There is a wealth of information regarding the
general population's uptake of COVID-19 vaccines, but there is not nearly as much information
regarding cancer patients.
Multiple studies are seeking to find factors associated with COVID-19 vaccine hesitancy in
the general population. There are very few published studies that have specifically examined
factors associated with vaccine hesitancy (or barriers to vaccination) in cancer patients.
The investigators aim to identify barriers to COVID-19 vaccination in the adult cancer
population. Further, a comparison between vaccine acceptance and/or hesitancy in patients
with prior known COVID-19 positivity and those without prior COVID-19 positivity has not been
conducted yet, to the knowledge of the study team.
Additionally, the safety and efficacy profiles of COVID-19 vaccination in cancer patients has
yet to be determined. Admittedly, the efficacy profile of COVID-19 vaccination is an ongoing
process and situation. One study did determine that only 1 dose of the
Pfizer-Biopharmaceutical New Technologies was not efficacious in producing positive
anti-Spike protein titers 21 days after a single vaccine inoculum. Only 21 of 56 solid cancer
patients and 8 of 44 hematological cancer patients sero-converted after a single dose. The
general findings here were that patients with cancer need an early or day 21 second dose of
the Pfizer vaccine in order for positive anti-S titers to be present in their blood. It is
still unknown if these patients or those in the general population will require annual (or
another time-frame) boosters.
This study does aim to establish a safety profile in those PSCI patients who have been
vaccinated, as the investigators will be inquiring about side effects from vaccination. There
is little information available about the safety profile of COVID-19 vaccination in cancer
patients. The investigators will be asking participants about the side effects they may have
experienced after vaccination.
One known side effect that may have an impact on cancer treatment and outcomes includes
axillary and supraclavicular lymph node enlargement. According to this study, more patients
who received the Moderna Inc. vaccine had ipsilateral axillary lymphadenopathy (lymph node
enlargement in the same side that the vaccine was administered) than those who received the
Pfizer vaccine. The investigators will be surveying patients to examine whether or not this
phenomenon occurred in PSCI patients and what the outcome was (no change in treatment, delay
in treatment, stoppage of treatment, for example).
