Background: The phase III RxPONDER trial has impacted treatment for node-positive(1-3), hormone receptor-positive, HER2-negative breast cancer with 21-gene recurrence score (RS) ≤ 25. We investigated how these findings apply to different racial and ethnic groups within the trial.
Methods: The trial randomized women to endocrine therapy (ET) or to chemotherapy plus ET.
Quality cancer care is efficient, accessible, coordinated, and evidence-based. Recognizing the necessary key components, development of pathways and guidelines to incorporate these key domains, and finally respectful adaptation to cultural differences can ensure that cancer care globally is of the highest quality. This quality care should be judged not only on how it optimizes health outcomes for patients, but also its impact on the care providers and the global community.

Methods: Patients undergoing neoadjuvant chemotherapy (NAC) for locally-advanced breast cancer were imaged at three timepoints (pre, mid, and post-NAC), prior to surgery. Imaging included diffusion-weighted and dynamic contrast-enhanced (DCE-) MRI and quantitative F-FDG PET.
Rapidly expanding systemic treatment options, combined with improved screening, diagnostic, surgical, and radiotherapy techniques, have led to improved survival outcomes for many cancers over time. However, these overall survival gains have disproportionately benefited patients in high-income countries, whereas patients in low- and middle-income countries (LMICs) continue to experience challenges in accessing timely and guideline concordant care. In September 2022, the Accelerating Anticancer Agent Development and Validation workshop was held, focusing on global cancer drug development.
View Article and Find Full Text PDFPurpose: The number of systemic anticancer therapy (SACT) regimens has expanded rapidly over the last decade. There is a need to ensure quality of SACT delivery across cancer services and systems in different resource settings to reduce morbidity, mortality, and detrimental economic impact at individual and systems level. Existing literature on SACT focuses on treatment efficacy with few studies on quality or how SACT is delivered within routine care in comparison to radiation and surgical oncology.

Objective: To investigate whether adherence to cancer prevention recommendations before, during, and 1 and 2 years after breast cancer treatment was associated with disease recurrence or mortality.
As the voice of cancer care clinicians and the patients they serve, ASCO has taken steps to elevate awareness about biosimilar products and their use in oncology. In 2018, ASCO released its Statement on Biosimilars in Oncology which was subsequently published in the to serve as an educational tool which highlighted and provided guidance on several topical areas surrounding biosimilars. At the time of its publication, the US Food and Drug Administration (FDA) had approved eight biosimilar products for use in the United States, including one product for use as a supportive care agent in the cancer setting and two products for use in the treatment for cancer.

Background: The availability of safe and effective COVID-19 vaccines has enabled protections against serious COVID-19 outcomes, which are particularly important for patients with cancer. The American Society of Clinical Oncology Registry enabled the study of COVID-19 vaccine uptake in patients with cancer who were positive for severe acute respiratory syndrome-coronavirus 2.
Methods: Medical oncology practices entered data on patients who were in cancer treatment.
Background: Poly(ADP-ribose) polymerase (PARP) inhibitors are effective in germline BRCA1 or BRCA2 (BRCA1/2) mutation-associated metastatic breast cancer. However, studies evaluating PARP inhibitors plus platinum-based chemotherapy in germline BRCA1/2-wildtype triple-negative breast cancer are scarce. A large proportion of germline BRCA1/2-wildtype triple-negative breast cancer shows homologous recombination deficiency (HRD), resulting in a BRCA-like phenotype that might render sensitivity to PARP inhibitors.

Methods: Estimates of new female breast cancer cases and deaths in 2020 were abstracted from the GLOBOCAN database.
A concerted commitment across research stakeholders is necessary to increase equity, diversity, and inclusion (EDI) and address barriers to cancer clinical trial recruitment and participation. Racial and ethnic diversity among trial participants is key to understanding intrinsic and extrinsic factors that may affect patient response to cancer treatments. This ASCO and Association of Community Cancer Centers (ACCC) Research Statement presents specific recommendations and strategies for the research community to improve EDI in cancer clinical trials.

Our specific aim was to compare usual care and a tablet-based fatigue education and prescription program for effects on level of fatigue (primary outcome) and satisfaction with fatigue and amount of exercise (secondary outcomes).
Methods: In a four-week pretest/posttest randomized study, 279 patients with cancer completed a touch screen fatigue assessment and daily paper-based activity logs.
Background: The recurrence score based on the 21-gene breast-cancer assay has been clinically useful in predicting a chemotherapy benefit in hormone-receptor-positive, human epidermal growth factor receptor 2 (HER2)-negative, axillary lymph-node-negative breast cancer. In women with positive lymph-node disease, the role of the recurrence score with respect to predicting a benefit of adjuvant chemotherapy is unclear.
Methods: In a prospective trial, we randomly assigned women with hormone-receptor-positive, HER2-negative breast cancer, one to three positive axillary lymph nodes, and a recurrence score of 25 or lower (scores range from 0 to 100, with higher scores indicating a worse prognosis) to endocrine therapy only or to chemotherapy plus endocrine (chemoendocrine) therapy.
Purpose: Metastatic hormone receptor (HR)-positive, HER2-negative breast cancer is an important cause of cancer mortality. Endocrine treatment with or without additional targeted therapies has been the mainstay of treatment. This trial was designed to evaluate the combination of fulvestrant plus everolimus versus fulvestrant, everolimus, and anastrozole compared with fulvestrant alone in the first-line treatment of advanced HR-positive, HER2-negative breast cancer.

Methods: Participating practices enter data on patients with SARS-CoV-2 infection in cancer treatment.
Purpose: Serum thymidine kinase 1 (sTK1) activity is associated with poor prognosis in metastatic breast cancer (MBC). We assessed the prognostic effect of sTK1 in patients with hormone receptor-positive MBC treated on a prospective randomized trial of anastrozole (A) versus A plus fulvestrant (A + F).
Patients And Methods: sTK1 was assessed in 1,726 serums [baseline (BL), cycles 2, 3, 4, and 7] using the DiviTum assay.
Purpose: This guideline updates recommendations of the ASCO guideline on chemotherapy and targeted therapy for patients with human epidermal growth factor receptor 2-negative metastatic breast cancer (MBC) that is either endocrine-pretreated or hormone receptor (HR)-negative.
Methods: An Expert Panel conducted a targeted systematic literature review guided by a signals approach to identify new, potentially practice-changing data that might translate into revised guideline recommendations.
Results: The Expert Panel reviewed abstracts from the literature review and retained 14 articles.
Introduction: Neoadjuvant chemotherapy is standard treatment for locally advanced breast cancer (LABC) or inflammatory breast cancer (IBC). We hypothesized that adding sunitinib, a tyrosine kinase inhibitor with antitumor and antiangiogenic activity, to an anthracycline and taxane regimen would improve pathologic complete response (pCR) rates to a prespecified endpoint of 45% in patients with HER2-negative LABC or IBC.
Methods: We conducted a multicenter, phase II trial of neoadjuvant sunitinib with paclitaxel (S+T) followed by doxorubicin and cyclophosphamide plus G-CSF for patients with HER2-negative LABC or IBC.
Background: Nonadherence to aromatase inhibitors (AIs) is common and increases risk of breast cancer (BC) recurrence. We analyzed factors associated with nonadherence among patients enrolled in S1105, a randomized trial of text messaging.
Methods: At enrollment, patients were required to have been on an adjuvant AI for at least 30 days and were asked about financial, medication, and demographic factors.
Malignancy has historically prohibited solid organ transplant; however, patients with effectively treated, favorable-risk cancers should not necessarily be eliminated as transplant candidates. These cases require careful review by a multidisciplinary team. Here, we report the case of a woman with end-stage heart failure undergoing heart transplant evaluation during the COVID pandemic who was found to have early-stage, hormone receptor-positive breast cancer.
