- Those who had solid tumors and were in remission faced approximately the same proportion of outcome (% mortality) as those who were in remission after having haematological malignancies (diagnosed with COVID-19)
- Any form of therapy in cancer patients with covid resulted in about 2 times more mortality
- Cytotoxic therapy in patients with haematological malignancies had the greatest proportion of mortality compared to other forms of therapy in both types of cancers

Michigan State University

- Participants were selected if they presented with any malignancy or were diagnosed with cancer before
- The participants had COVID-19 
- The study lasted for a month upon diagnosis of COVID-19
- The study aimed at determining the mortality rate in these patients
- 13% of the patients died
- Those from the Northeast and Midwest parts of US and those from Canada had lower mortality cases
- Cancer type, race, and whether or not the patient was obese did not have an impact on the mortality rate
- Mortality was high for patients with COVID-19 and cancer, and there was an association with age and other general risk factors
- Hydroxychloroquine and azithromycin (cancer drugs) were also given to patients, but their benefits or harms in relation to COVID-19 are unknown


Cancer patients and COVID-19

Clinical impact of COVID-19 on patients with cancer

Figure 1
- The odds ratios were calculated for factors that caused mortality in cancer patients with COVID-19 (comorbidity) within 30 days
- The odds ratio for people who were former smokers compared to other smoking categories was the highest, at approximately 1.50; this indicates a 50% increase in mortality in that group
- The odds ratio for those who underwent treatment for COVID-19 with both hydroxychloroquine and azithromycin expercined greater mortality compared to those who took either one of the drugs
- The odds ratio for mortality in those who used both hydroxychloroquine and azithromycin came out to be 3.00; this means that there is a 3 times more likely chance that the patient will die within 30 days compared to those who take only one of the drugs
