Additionally, elevations in ferritin, high-sensitivity C-reactive protein, erythrocyte sedimentation rate, procalcitonin, prothrombin time, interleukin-2 (IL-2) receptor, and interleukin-6 (IL-6) were observed in cancer patients, which may indicate specific immune and inflammatory reactions in COVID-19 patients with cancer. This evidence concerns the gene IL6 and cancer.
