Breast cancer survival in Mexico between 2007 and 2016 in women without social security: a retrospective cohort study

Survival Outcomes of Patients With Breast Cancer in a Mexican Population

“…In all cases, they were higher than those in the US population 17 and other developed countries, where most of the population are diagnosed in early stages. The proportion of patients diagnosed with metastatic disease was 7.3%, which is not different from that reported in other publications, 6 , 9 , 14 , 15 although higher than that reported in patients treated in private settings. 17 The distribution of breast cancer subtypes is consistent with that reported worldwide.…”

“…Most of the patients (64%) were found in stages II-III, slightly lower than in the study by Reynoso-Noverón 6 (72.8%) with a Government Insurance population (previously Seguro Popular), and similar to another Mexican cohort reported by Maffuz-Aziz et al, 15 in which, of 4,411 patients, 45% were staged IIB and III; classifying in the same way, 43% of our patients were found in these stages, which is less than reported in patients who lack some type of social security in whom stages at diagnosis are more advanced. 9 A recent analysis on health inequity in Mexican women with breast cancer demonstrated a significant association between socioeconomic status and educational level with worse prognosis. 16 This reflects that the gap and disparity in health services in our country has an impact on survival.…”

“…The 5-year OS rate was 90.4% for the entire cohort, like described in developed countries, 19 higher than other Latin American countries, 20 , 21 and also higher compared with what was reported by Reynoso-Noverón et al, 6 with a 5-year OS of 82% and even higher with respect to patients without social security, reported at 72%. 9 These survival data are not comparable since different populations were analyzed: the patients reported without social security are part of a data cohort from the entire country, where there are records from different states, some of which have less infrastructure and lower quality in health services. Our cohort is a selected population within our health system, in a centralized, specialized, high-patient-volume hospital.…”

“…Differences in survival were found according to age and stage, but there were also important differences associated with the state of residence and access to available health services. 9 Therefore, it is imperative to know the updated statistics on epidemiology and survival outcomes in our hospital, given the impact it generates in terms of the need to care for the population that is representative of our country.…”

Association Between Interleukin 6 and C-Reactive Protein Serum Levels and Body Composition Compartments and Components in Breast Cancer Survivors

“…Breast cancer (BC) is the leading cause of mortality from malignant neoplasms in Mexican women, with an age-standardized rate of 10.6 per 100,000 women (Ferlay et al, 2020) and a 5-year survival rate of 72.2%, according to a study cross-linking reimbursement claims for 56,847 Mexican women treated for breast cancer between 2007 and 2016 to a mortality registry conducted in women without social insurance (Unger-Saldaña et al, 2023). Cancer survivors have an increased risk of cancer recurrence and mortality.…”
