Abbreviations: OR = Odds Ratios; CI = confidence interval, N = number of patients.

*Predictive factors for surgery alone without the variable M stage because no patient with stage M1 had surgery alone.

†Predictive factors for BCS plus adjuvant therapy without the variable M stage because only 4 patients with stage M1 received BCS plus adjuvant therapy.

‡patient single, divorced or widowed.

§Interaction age and diagnosis circumstances.

NB: Multivariate logistic regression analyses were adjusted for age, TNM stage, period, diagnosis circumstances, comorbidities, histoprognostic SBR grade, tumour type, hormone receptors, matrimonial status, and place of residence.
