Breast cancer, a disease that strikes fear into the hearts of many women, has seen significant shifts in mortality rates among young women over the past decade. Dr. Adetunji Toriola, an esteemed professor at Washington University School of Medicine, delved deep into the data to uncover these intriguing trends.
“Understanding recent trends in mortality will enable us to assess progress over the years and inform where to direct resources to reduce cancer burden in this age group,”
explained Dr. Toriola, setting the stage for his groundbreaking study on breast cancer mortality in women aged 20-49.
Diving into the numbers, Dr. Toriola and his team pored over data from the SEER Program 17 registry, meticulously analyzing 11,661 breast cancer deaths among young women between 2010 and 2020. Their findings revealed a heartening decline in breast cancer mortality rates across all racial/ethnic groups during this period.
“Across all subtypes and racial/ethnic groups, incidence-based mortality declined from 9.70 per 100,000 women in 2010 to 1.47/100,000 in 2020.”
This significant drop signals a positive trend that underscores advancements in early detection and treatment modalities for breast cancer.
Among the various molecular subtypes examined – luminal A, luminal B, HER2-enriched, and triple-negative breast cancer – luminal A stood out with the most substantial decrease in mortality rates. However, an unexpected discovery emerged regarding luminal A’s ten-year survival rates based on age group.
“This was unexpected as luminal A is generally the least aggressive subtype with the most favorable prognosis,”
remarked Dr. Toriola. The lower ten-year survival rate for younger women with luminal A tumors hints at potential biological intricacies that warrant further investigation.
While advancements in treatment options have undoubtedly contributed to improved outcomes for young women battling breast cancer, glaring disparities persist among different racial/ethnic groups. Non-Hispanic Black women continue to face higher incidence-based mortality rates compared to their counterparts.
Dr. Toriola pointed out that post-2016 saw more pronounced declines in mortality rates attributed to enhanced treatment options like CDK4/6 inhibitors and expanded access to precision medicine for hormone receptor-positive cancers like luminal A.
“We must continue to perform impactful research…and advocate for access to high-quality treatment and care for all women,”
emphasized Dr. Toriola when discussing future strategies to further reduce breast cancer mortality rates among young women.
As we navigate through these complex statistics and emerging trends, one thing remains clear – there is still much work to be done in bridging existing gaps and ensuring equitable access to life-saving interventions for all women fighting against breast cancer.
