The study by morante et al was presented at the 2018 san antonio breast cancer symposium (abstract gs2-05). The researchers then looked to see how a delay in chemotherapy affected the risk of cancer recurrence and survival.   a recent meta-analysis that included data on 15,327 patients reported that each 4-week delay in the initiation of adjuvant chemotherapy resulted in a 6 increase in the risk of death (hr, 1.).   in 2015, an estimated 231 840 cases of invasive breast cancer were diagnosed in the united states. 1 improvements in breast cancer treatment and early detection have resulted in a decrease in the mortality rates of patients with breast cancer in the last decades.
