Comorbidities Negatively Impact Breast Cancer Survival
Missouri has a high breast cancer mortality rate, as well as high rates of type 2 diabetes, cardiovascular disease (CVD), and hypertension, which present more often in individuals who are poor, those living in rural areas, African Americans, and older adults. Women with comorbidities at the time of breast cancer diagnosis may have a worse prognosis, so researchers assessed survival disparities among these patient populations. According to the findings presented at the , comorbidities can negatively impact overall breast cancer survival.
Glutathione Plays a Role in Treatment-Related CINV
Chemotherapy-induced nausea and vomiting (CINV) can negatively affect nutritional intake, ability to work, and treatment adherence. Research suggests that younger age and female gender are the strongest predictors of CINV, but those may not be the only factors, particularly for delayed nausea, according to research findings presented at the San Antonio Breast Cancer Symposium on December 5, 2018.
Circulating Tumor Cells Predict Survival
Circulating tumor cells (CTCs) are identified in 20%–25% of patients with nonmetastatic breast cancer, and recent research suggests that detection of CTCs at five-year follow-up may predict late recurrence for nonmetastatic, estrogen receptor-positive (ER+), human epidermal growth factor receptor 2-negative (HER2–) breast cancer. In a study presented at the , researchers from the University of Texas MD Anderson Cancer Center found that the presence of CTCs in patients with nonmetastatic breast cancer was associated with shortened relapse-free survival (RFS), regardless of the subtype.

Study Identifies Novel Triplet Therapy for HR+/HER2+ Breast Cancer
Researchers from the University of Colorado Denver Young Women Breast Cancer Translational Program in Aurora identified a potential triplet combination for the treatment of hormone receptor-positive (HR+) human epidermal growth factor receptor 2-positive (HER2+) breast cancer: HER2-targeted small molecule inhibitor tucatinib, CDK4/6 inhibitor palbociclib, and selective estrogen receptor blocker fulvestrant. They presented the findings at the .
Highly Emetogenic Chemotherapy Still Contributes to Potentially Avoidable Adverse Events
The Centers for Medicare and Medicaid Services (CMS) implemented an oncology outcome measure to assess the quality of care and determine outpatient hospital payment (OP-35: Admissions and Emergency Department Visits for Patients Receiving Outpatient Chemotherapy). The measure assesses 30-day postchemotherapy rates of inpatient or emergency department (ED) events deemed “potentially avoidable” because of an association with any of the 10 CMS-defined toxicities: anemia, dehydration, diarrhea, fever, nausea, emesis, neutropenia, pain, pneumonia, or sepsis. Researchers sought to assess those events when linked to highly emetogenic chemotherapy (HEC) in patients treated with anthracycline plus cyclophosphamide (AC), carboplatin, or cisplatin. They presented the findings at the .
Social Support May Play a Role in Treatment Adherence
Many women discontinue adjuvant endocrine therapy (AET) because of adverse events (AEs), and only half remain adherent at five years. Researchers from the University of Southern California, Los Angeles, found that continued social support for those women may improve AET adherence. They presented the findings at the .
Socioeconomic Factors Predict Survival in Nonmetastatic Breast Cancer
Racial and regional disparities impact the incidence of, mortality from, and survival from breast cancer, but the role of other socioeconomic factors is unclear.

They presented the findings at the .
Breast MRI Protocol Improves Patient Care
Magnetic resonance imaging (MRI) can help diagnose breast cancer, but it is costly. Leadership at the University of Washington in Bellingham developed a protocol to improve the timeliness of care, moving the time of MRI prior to surgeon evaluation, and found that it led to enhanced patient care, eliminated delays in treatment, avoided unnecessary tests, shifted appropriate care to primary-care providers, and provided all necessary data prior to initial surgical consultation. They presented the findings at the .
Patients Rank the Importance of PRO Measures Differently
Patient-reported outcomes (PROs) can improve patient satisfaction and potentially impact survival. However, PRO data are not well-collected outside of the research setting.

They presented the findings at the .
Time to Treatment Discontinuation Shorter in Patients Who Receive First-Line Palbociclib
Current treatment guidelines recommend sequential hormone therapy for patients with hormone receptor-positive (HR+) metastatic breast cancer who are not in visceral crisis and whose disease is not refractory to endocrine treatment. Second-line fulvestrant monotherapy is a treatment option for patients in whom disease progresses after first-line palbociclib. Researchers used real-world data to evaluate the time to treatment discontinuation (TTD) of second-line fulvestrant in patients with HR+ human epidermal growth factor receptor 2-negative (HER2–) metastatic breast cancer who did (n = 88) and did not (n = 100) receive first-line palbociclib and found it was shorter in patients who received palbociclib. They presented the findings at the .
Overall Survival From Breast Cancer Differs Based on Tumor Type and Location
Triple-negative breast cancer tumors are thought to be more immunogenic than other breast cancer subtypes, such as luminal A/B or human epidermal growth factor receptor 2-positive (HER2+) tumors. Among all breast cancers, tumors appear more commonly in the upper outer quadrant. However, it is not clear whether expression of immune response genes vary with tumor location among the different subtypes. Researchers assessed gene expression associated with immune response pathways to identify potential treatment targets and presented the findings at the .
