Demonstrate association between tumor size, margins, histological type, histological grade, estrogen and progesterone receptors and axillary recurrence in patients with breast cancer T1-T2, N0 with negative sentinel node biopsy Method: The present study is of cases and controls nested in a cohort of 98 patients with breast cancer T1-T2, N0 with negative sentinel node biopsy hospitalized in the Breast, Bone and Mixed Tumors Department of the Regional Institute of Neoplastic Diseases from January 1 of 2014 to December 31 of 2020. For the descriptive statistics, absolute frequencies and relative frequencies were used, while measures of central tendency and dispersion were used in the absolute variables. For inferential statistics, Pearson’s chi-square test was used for qualitative variables and the statistician was Odds Ratio with a significance level of 5%. Results: Of the 98 patients, 3 recurrences (3.1%) were detected at 6.8 and 13 months after biopsy. Of the total recurrences, 66.7% were in T2N0 state, 33.3% had negative estrogen receptors, 66.7% had negative progesterone receptors, 100% showed histologic type to infiltrating ductal carcinoma, a histological grade II, a tumor size of 2 cm or more and margins of less than 2 mm Conclusions: The risk of presenting axillary recurrence after a negative sentinel node is low, proving to be a confineable diagnostic test with a low recurrence rate, being suitable for staging and follow-up of patients
