Survival and Time to Initiation of Adjuvant Chemotherapy Among Breast Cancer Patients in Uruguay.

Patients who started chemotherapy more than 90 days following surgery and those with stage III disease or underwent mastectomy and/or axillary lymph node dissection who initiated it between 61 and 90 days had a worse OS. Multiple factors are involved in the time between surgery and the initiation of chemotherapy, and further studies are needed to evaluate which of these factors influence the delay of chemotherapy in order to design strategies to avoid such delays and their negative impact on survival.
