Abstract 1594P
Background
The COVID-19 pandemic continues to have a serious impact on many people, including cancer pts. The US CDC and oncology groups (ASCO, ESMO, ACS) made recommendations as to what high risk groups should be vaccinated first which includes cancer pts. Users of Belong.life, a worldwide, free, and voluntary, digital health application for cancer pts, replied to a targeted survey including demographic & clinical questions related to the pts cancers, ongoing therapies and the Covid 19 vaccination characteristics, and interactions.
Methods
In this prospective study, 1069 cancer pts, Belong.life users, voluntarily replied to a survey asking demographic and clinical questions related to their Covid 19 vaccination and cancer status characteristics.
Results
Most of the pts were North American based (91 %), with 6.3 % from Europe and 2.6% from the rest of the world. 72% were between 50-69 years of age, and 79.5% were females. Five most common diagnosis were Breast Cancer (35.2%), gynecological (14.4%), gastrointestinal (13.3%), lung cancers (9.7%) and genitourinary (7%). 59% of the pts received chemotherapy,14.2% immunotherapy and 32.8% had radiotherapy over the past 12 months prior to receive the Covid 19 vaccination, which consisted of mRNA vaccines in 82.2% (Pfizer 46.2%, Moderna 36%). 4.9% of the pts refused vaccination. 82.3% of the pts had none (39.3%) or mild (43%) side-effects (S/E) and only 2.4% reported severe S/E. Most S/E lasted 1-3 days (89.4%) consisting mainly of sore arm (42.5%), headache (23.3%), fatigue (21.1%), and temperature (18.5%). Swollen lymph-nodes and allergic reactions were only reported in 0.7% (each). 49% of the pts were vaccinated while actively engaged on treatment, and in 96% there was no delay, interruption, or stoppage of the anticancer therapy.
Conclusions
This is the first large report on Real word data voluntarily obtained from 1069 Belong.life users undergoing anticancer treatment with 90% of them receiving a Covid 19 vaccination. The large majority of pts had none or mild S/E (82.3%), and those were short lived (1-3 days in 89.4%) while only in 2% it was graded as severe. In 96% of the pts their ongoing anticancer therapy did not necessitate to be delayed, interrupted, or stopped.
