Chemotherapy delays among cancer patients in Iran during COVID-19 pandemic

We found an association between the male gender, colorectal cancer, metastatic disease and higher rates of moderate delays. The initial COVID-19 pandemic wave was associated with increased severe delays in the chemotherapy course. According to the findings of this study, male cancer patients and those with metastatic cancer are at risk of poorer prognosis due to lower adherence to treatment. These findings can assist policymakers in developing targeted strategies to lessen the delay rates in the more vulnerable population.
