Clinical late-stage of breast cancer in the state of Jalisco: magnitude and spatial-temporal variations. Acta univ [online]. 2020, vol.30, e2487.  Epub Mar 26, 2021.

Official records indicate that in Jalisco, Mexico, the diagnosis of breast cancer (BC) in women is usually performed at advanced stages. Using geo-referenced data of patients treated at a third-level hospital, the magnitude and spatialtemporal variation associated with late clinical stage (IIb, IIIa, IIIb, IIIc, IV) by municipality of residence was identified during 2013-2015. The municipalities of Acatic, Atoyac and Zapotlanejo showed an increase in the estimated rate for this period, whose value was 44.6, 17.7 and 19.2 per hundred thousand women older than 20 years of age, respectively. In addition, the risk of late-stage breast cancer increased up to four times and in accordance to the patient’s municipality of residence. The results show the municipalities where it is required to improve the detection and diagnosis of BC and, especially, to guarantee an early treatment for women who reside in the places of higher risk, in compliance with the guidelines established in the NOM 041-SSA2-2011.
