Introduction and importance: Breast cancer is the most common type of cancer in women, with 30 % being metastatic breast cancer. Cancer is known to be a comorbid Covid-19 infection. Interleukin-6 (IL-6) is one of the findings of inflammatory activity due to Covid-19 infection. We report IL-6 levels as a prognostic factor for survival rate in patients with liver metastatic breast cancer.
Case presentation: We report five cases of liver metastatic breast cancer with various types of primary breast cancer. All patients are infected with Covid-19. IL-6 levels were reported to be elevated in all five patients. All patients were treated according to the national guidelines for the care of Covid-19 patients. All patients are reported to have deceased after being treated for Covid-19 infection.
Clinical discussion: Metastatic breast cancer has a low prognostic rate. Cancer has been recognized as one of the comorbidities and increases the severity and mortality of Covid-19 infection. Elevated levels of IL-6 are caused by an immune response to infection, and can worsen the outcome of breast cancer patients. Changes in IL-6 levels implicate the survival rate of metastatic breast cancer patients and outcomes during the treatment of Covid-19 infection.
Conclusion: Elevated levels of IL-6 can be a prognostic factor of the survival rate of metastatic breast cancer patients during the treatment of Covid-19 infection.
