Weekly pediatric cases of COVID-19 exceeded 200,000 for just the second time during the pandemic, while new vaccinations in children continued to decline.

There were almost 204,000 new cases reported in children during the week of Aug. 20-26, the highest 1-week total since the peak of 211,000 in mid-January. The weekly count has now increased for 9 consecutive weeks, during which time it has risen by over 2,300%, the American Academy of Pediatrics and the Children’s Hospital Association said in their weekly COVID-19 report. Total cases in children number almost 4.8 million since the pandemic started.

Vaccinations in children are following a different trend. Vaccine initiation has dropped 3 weeks in a row for both of the eligible age groups: First doses administered were down by 29% among 12- to 15-year-olds over that span and by 32% in 16- to 17-year-olds, according to data from the Centers for Disease Control and Prevention.

Since vaccination for children aged 12-15 years started in May, 49% had received at least one dose, and just over 36% were fully vaccinated as of Aug. 30. Among children aged 16-17 years, who have been eligible since December, 57.5% had gotten at least one dose of the vaccine and 46% have completed the two-dose regimen. The total number of children with at least one dose, including those under age 12 who are involved in clinical trials, was about 12 million, the CDC said on its COVID Data Tracker.
 

Hospitalizations are higher than ever

The recent rise in new child cases has been accompanied by an unprecedented increase in hospitalizations. The daily rate in children aged 0-17 years, which did not surpass 0.30 new admissions per 100,000 population during the worst of the winter surge, had risen to 0.45 per 100,000 by Aug. 26. Since July 4, when the new-admission rate was at its low point of 0.07 per 100,000, hospitalizations in children have jumped by 543%, based on data reported to the CDC by 5,251 hospitals.

A total of 52,245 children were admitted with confirmed COVID-19 from Aug. 1, 2020, when the CDC dataset begins, to Aug. 28, 2021. Those children represent 1.9% of all COVID admissions (2.7 million) in the United States over that period, the CDC said.

Total COVID-related deaths in children are up to 425 in the 48 jurisdictions (45 states, New York City, Puerto Rico, and Guam) that provide mortality data by age, the AAP and the CHA said.

Record-high numbers for the previous 2 reporting weeks – 23 deaths during Aug. 20-26 and 24 deaths during Aug. 13-19, when the previous weekly high was 16 – at least partially reflect the recent addition of South Carolina and New Mexico to the AAP/CHA database, as the two states just started reporting age-related data.

Metastatic triple-negative breast cancer (TNBC) is a heterogeneous, biologically complex subtype, with continuing efforts to identify therapeutic targets. The PI3K/AKT signaling pathway plays a key role in cell proliferation, survival, invasion, and metabolism. In the phase II LOTUS trial (Dent et al) including 124 patients with advanced TNBC (no prior therapy for advanced disease), addition of the oral AKT inhibitor, ipatasertib, to paclitaxel led to a numerical improvement in OS that was not statistically significant. The median OS was 25.8 vs 16.9 months for the ipatasertib-paclitaxel vs placebo-paclitaxel, respectively (HR 0.80, 95% CI 0.50-1.28). Findings from cohort A of the phase III IPATunity130 trial showed that ipatasertib-paclitaxel did not lead to a statistically significant improvement in PFS vs placebo-paclitaxel in patients with PIK3CA/AKT1/PTEN-altered advanced TNBC in the first-line metastatic setting (mPFS 7.4 vs 6.1 months, respectively; HR 1.02, p=0.9237). These findings support further investigation into predictors of response and other molecular markers that may play a role in the diversity of mTNBC. 

Endocrine therapy resistance remains a significant challenge in advanced HR+/HER2- breast cancer, and initial studies with the oral histone deacetylase inhibitor, etinostat, showed promise in this space. Unfortunately, these findings were not upheld in the phase III E2112 trial (Connolly et al), which failed to show an improvement in PFS or OS with exemestane-etinostat (EE) compared to exemestane-placebo (EP) among patients who had progressed on prior non-steroidal AI. Median PFS was 3.3 vs 3.1 months (HR 0.87; p=0.30) and median OS was 23.4 vs 21.7 months (HR 0.99; p=0.94) for the EE vs EP arms, respectively. The combination of an alternative HDAC inhibitor, tucidinostat, has been approved in China in combination with exemestane based on PFS benefit (3.6 months) in the phase III ACE trial. There are notable difference between E2112 and ACE trials, including patient population and design, and importantly OS has not been reported for the latter. The relatively short mPFS and low response rate (5-6%) in E2112 argues for more efficacious therapeutics. There is also value in correlative studies to help further elucidate if there is a role for HDAC inhibitors in this space.

Although adjuvant endocrine therapy has had a significantly beneficial effect on outcomes in early-stage HR+ breast cancer, late recurrences are characteristic of the luminal subtype, and have led to trials investigating extended adjuvant endocrine therapy. The phase III SALSA trial included 3484 women with early HR+ breast cancer who had received 5 years of adjuvant endocrine therapy with randomization to anastrozole for an additional 2 vs 5 years (comparing total of 7 vs 10 years). There was no significant difference in disease-free survival (DFS) at 8 years (73.6% vs 73.9% in the 2 vs 5-year groups, respectively; HR 0.99, p=0.90). Additionally, there was a lower risk of bone fracture in the 2 vs 5-year group (4.7% vs 6.3%; HR 1.35). It is essential to balance modest benefits with toxicities of prolonged AI use, and valuable to identify high-risk patients who may benefit from extended adjuvant endocrine therapy.

Key clinical point: Initiation of statin treatment within 12 months of diagnosis improves survival in women with stage I-III triple-negative breast cancer (TNBC).

Major finding: Statin treatment was initiated in 2,281 patients within 12 months of diagnosis. In 1,534 patients with TNBC, statin use was associated with a significant improvement in breast cancer-specific survival (standardized hazard ratio [HR], 0.42; P = 0.022) and overall survival (HR, 0.70; P = 0.046). No significant association was observed between statin use and survival in patients without TNBC.

Key clinical point: A survey-based study shows higher chemotherapy use in patients with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced breast cancer with poor prognostic factors.

Major finding: At least 1 poor prognostic factor was reported in 63% of patients, with varying degrees of overlap between factors. The ability of patients to maintain usual activities was more common in patients without poor prognostic factors. Chemotherapy was prescribed more frequently in patients with poor prognostic factors, whereas endocrine therapy and nonopioid analgesic were more common in patients without poor prognostic factors.

Study details: Real-world data were derived from a large multinational Adelphi Real World Disease Specific Programme survey of 410 oncologists and 2,259 patients with HR-positive, HER-negative advanced breast cancer.

Key clinical point: Women aged 65 years and above with pathogenic variants (PVs) in BRCA1/2, checkpoint kinase 2 (CHEK2), and partner and localizer of the BRCA2 (PALB2) genes are at an increased risk for breast cancer.

Major finding: The rate of PVs was 3.18% in women with breast cancer and 1.48% in those without. PVs in BRCA1 (odds ratio [OR], 3.37), BRCA2 (OR, 2.64), PALB2 (OR, 3.09), and CHEK2 (OR, 2.13) and were associated with moderate risk for breast cancer. The remaining lifetime risk was 18.4%, 18.7%, 15.9%, and 14.9% for BRCA1, BRCA2, PALB2, and CHEK2 PVs

Key clinical point: Women aged 65 years and above with pathogenic variants (PVs) in BRCA1/2, checkpoint kinase 2 (CHEK2), and partner and localizer of the BRCA2 (PALB2) genes are at an increased risk for breast cancer.

Major finding: The rate of PVs was 3.18% in women with breast cancer and 1.48% in those without. PVs in BRCA1 (odds ratio [OR], 3.37), BRCA2 (OR, 2.64), PALB2 (OR, 3.09), and CHEK2 (OR, 2.13) and were associated with moderate risk for breast cancer. The remaining lifetime risk was 18.4%, 18.7%, 15.9%, and 14.9% for BRCA1, BRCA2, PALB2, and CHEK2 PVs

Key clinical point: Targeted breast screening in women aged 30-60 years at an increased familial risk is associated with good long-term survival.

Major finding: A total of 649 breast cancers were detected during the follow-up of 129,119 person-years. Breast cancer-specific survival at 10 years was 91.3%, which was higher than the previously reported survival in women presenting with primary breast cancer. Moreover, 10-year survival for women diagnosed at age 40 years and below was 93.8%.

Study details: This was a retrospective study of women who were offered enhanced screening with annual mammography starting at age 35 years or 5 years younger than the youngest affected relative, with the upper age limit of 50 years for women at moderate risk and 60 years for those at high risk.

Disclosures: This work was supported by the National Institute for Health Research and Prevent Breast Cancer. Dr. DG Evans received consulting fees from companies. The other authors declared no conflict of interests.

Key clinical point: Extended intermittent and continuous letrozole yield similar disease-free survival in postmenopausal women with hormone receptor (HR)-positive breast cancer. Circulating estrogen levels were restored after letrozole interruption.

Major finding: There was no difference in 7-year disease-free survival between intermittent and continuous letrozole groups (P = 0.64). The median change in estradiol levels after letrozole interruption was 141% vs. 2.2% with continuous letrozole during the same duration.

Study details: The Study of Letrozole Extension (SOLE) trial was an open-label, phase 3 study of 4,884 postmenopausal women with HR-positive, lymph node-positive, operable breast cancer, randomly assigned to extended intermittent or continuous letrozole. The SOLE-EST sub study (n=104) evaluated changes in circulating estrogen levels.

Disclosures: SOLE study was supported by Novartis and the International Breast Cancer Study Group. SOLE-EST was partially funded by the Belgian Foundation Against Cancer, Breast Cancer Trials Australia and New Zealand, and Susan G. Komen for the Cure.

Key clinical point: Adding trastuzumab to chemotherapy in patients with early-stage, epidermal growth hormone receptor 2 (HER2)-positive breast cancer lowers the rate of recurrence and mortality from breast cancer.

Major finding: Trastuzumab plus chemotherapy vs chemotherapy alone significantly reduced the rates of breast cancer recurrence (rate ratio [RR], 0.66; P < 0.0001) and death from breast cancer (RR, 0.67; P < 0.0001). The average absolute reduction in 10-year risk of recurrence was 9.0% (P < 0.0001) and in 10-year breast cancer mortality was 6.4% (P < 0.0001).

Study details: This was a meta-analysis of individual patient data from 7 randomized trials including 13,864 patients with early-stage, HER2-positive breast cancer who were randomly assigned to trastuzumab plus chemotherapy or chemotherapy alone.
