This is an excellent article demonstrating the stark changes in mortality pre- and post-Medicaid expansion. Further advocacy efforts are needed to enhance access to care, minimize negative social determinants of health. Maintaining the population at risk healthier, with access to guidelines-driven care should not be a matter of much debate, but an action point for our legislators.
Patients who are uninsured and belong to racial and ethnic minority groups or have low socioeconomic status have suboptimal access to health care, likely affecting outcomes. The association of the Affordable Care Act’s Medicaid expansion with survival among patients with metastatic breast cancer is unknown.
To examine the association between Medicaid expansion and mortality disparity among patients with de novo stage IV breast cancer.
Cross-sectional, population-based study of survival using Cox proportional hazards regression and difference-in-difference (DID) analysis of data from the National Cancer Database and patients diagnosed as having de novo stage IV breast cancer between January 1, 2010, and December 31, 2016, residing in states that underwent Medicaid expansion on January 1, 2014. The preexpansion period was January 1, 2010, to December 31, 2013; the postexpansion period was January 1, 2014, to December 31, 2016. Data were analyzed between September 4, 2020, and November 16, 2021.
Comparison of survival improvement between patients of racial and ethnic minority groups and White patients in the preexpansion and postexpansion periods. Because of small numbers in the specific racial and ethnic minority groups, these patients were combined into 1 category for comparisons.
Overall survival (OS) and 2-year mortality rate.
Among 9322 patients included (mean [SD] age, 55 [7] years), 5077 were diagnosed in the preexpansion and 4245 in the postexpansion period. The racial and ethnic minority group comprised 2545 (27.3%), which included 500 (5.4%) Hispanic (any race), 1515 (16.3%) non-Hispanic Black, and 530 (5.7%) non-Hispanic other including 25 (0.3%) American Indian or Alaska Native, 357 (3.8%) Asian or Pacific Islander, and 148 (1.6%) unknown, and 6777 (72.7%) were in the White patient group. In the preexpansion period, White patients had increased OS compared with patients of racial and ethnic minority groups (adjusted hazard ratio [aHR], 1.22; 95% CI, 1.10-1.35); this difference was not observed in the postexpansion period (aHR, 0.96; 95% CI, 0.86-1.08). A reduction in 2-year mortality was observed between the preexpansion and postexpansion periods (32.2% vs 26.0%). The adjusted 2-year mortality decreased from 40.6% to 36.3% among White patients and from 45.6% to 35.8% among patients of racial and ethnic minority groups (adjusted DID, −5.5%; 95% CI, −9.5 to −1.6; P = .006). Among patients in the lowest income quartile (n = 1510), patients of racial and ethnic minority groups had an increased risk of death in the preexpansion period (aHR, 1.28; 95% CI, 1.01-1.61) but lower risk in the postexpansion period (aHR, 0.75; 95% CI, 0.59-0.95). In this subset of patients, those of racial and ethnic minority groups had a greater reduction in 2-year mortality compared with White patients (adjusted DID, −12.8%; 95% CI, −22.2 to −3.5; P = .007).
In this cross-sectional study, survival differences observed between patients of racial and ethnic minority groups and White patients in the preexpansion period were no longer present in the postexpansion period. A greater reduction in 2-year mortality was observed among patients of racial and ethnic minority groups compared with White patients. These results suggest that policies aimed at improving equity and increasing access to health care may reduce racial and ethnic disparities in breast cancer outcomes.
MammaPrint did not predict distant recurrence, but it did predict patients who may benefit from extended hormonal therapy. We do have breast index, so now we have options. Breast index can predict the possibility of recurrence though by helping to determine the level of risk.
This study confirms what we saw in initial reports showing the addition of pembro increasing the rate of ypathological complete response (ypCR’s) in the neoadjuvant setting for triple-negative breast cancer (TNBC). New data shows a 5% improvement (87 vs 82%) in overall survival (OS) with the quadruplet. Higher gains but at higher cost of toxicity. The fact that adjuvant intraosseous (IO) does not seem to improve outcomes, but neoadjuvant chemo+IO does show intact tumor-immune interactions to create maximum treatment effectiveness is most likely real. Of note, this seems mostly independent of programmed death-ligand 1 (PDL1) status.
Adding Inavolisib to CKD4/6 inhibitor and AI improved progression-free survival (almost doubled 15 vs 7m) but toxicity was higher still in the single digits (hyperglycemia, diarrhea, stomatitis… all less than 6% G3/4).
Well done study showing a 20% decrease in recurrence risk when using dose dense therapy [EC]/D compared to conventional dose [FEC]/D. Sometimes it is worth it to push.
Myth busted. In aggressive breast cancer, no need to start chemotherapy now, ET and CKD4/6 inhibitors are better tolerated with significant progression-free survival (PFS) benefit and same response rate.
