December 10, 2020 - Women with stage 1 to 3 breast cancer who adhered to a diabetes risk reduction diet had improved survival versus those who did not follow this specific diet.

December 10, 2020 - Treatment with abemaciclib in combination with endocrine therapy significantly reduced the risk of invasive disease recurrence or death in patients with hormone receptor–positive, HER2-negative, node-positive, early breast cancer who had high Ki-67 tumors, suggesting that this feature can be used in conjunction with high-risk features to select patients for abemaciclib in the adjuvant setting.

December 10, 2020 — Oral paclitaxel and encequidar elicited lower rates of chemotherapy-induced peripheral neuropathy, as well as greater efficacy, in patients with metastatic breast cancer compared to intravenous paclitaxel.

December 10, 2020 - Mindfulness meditation and survivorship education classes reduced depressive symptoms in younger women treated for breast cancer.

December 10, 2020 - Fam-trastuzumab deruxtecan-nxki continued to showcase impressive signals of efficacy, including prolonged, durable responses and overall survival rates, as well as a tolerable safety profile in patients with HER2-positive metastatic breast cancer.

December 10, 2020 — The addition of ribociclib to endocrine therapy continued to significantly improve overall survival and delay subsequent chemotherapy compared with placebo, irrespective of endocrine partner in patients with hormone receptor–positive, HER2-negative breast cancer.

December 9, 2020 - Treatment with tamoxifen versus anastrozole did not yield any significant difference in terms of disease recurrence in postmenopausal women with locally excised ductal carcinoma in situ but understanding associated toxicities can inform care decisions.

December 9, 2020 - Whole breast irradiation, following breast-conserving surgery and adjuvant endocrine therapy, can be omitted from the treatment journey of low-risk, older patients with pT1-2 tumors (≥3 cm) who are on local control at 10 years.

Ian Kunkler, FRCP, FRCR, DMRT, MRCP, discusses the 10-year results of the PRIME 2 trial in patients with breast cancer

December 9, 2020 - The combination of oral paclitaxel and encequidar led to an estimated 26.5% reduction in the risk of death compared with intravenous paclitaxel in patients with metastatic breast cancer, according to updated phase 3 findings of the KX-ORAX-001 trial.

Kevin Kalinsky, MD, MS, discusses the initial results of the phase 3 RxPONDER trial in patients with hormone receptor–positive, HER2-negative breast cancer.

December 9, 2020 - The artificial intelligence–digital breast cancer risk discrimination platform PreciseDx was able to classify patients with Oncotype Dx low-risk recurrence scores with high accuracy using only hematoxylin and eosin stain images and limited clinical data.

December 9, 2020 - Intrinsic tumor subtype was found to be associated with prognosis in patients with hormone receptor–positive, HER2-negative advance breast cancer who received the CDK4/6 inhibitor ribociclib.

December 9, 2020 - Among women who underwent a mastectomy plus reconstructive surgery, those who received a breast cancer diagnosis, received chemotherapy and were younger were reported to have a higher risk of new chronic controlled substance use.

December 9, 2020 - Follow-up circulating tumor cell assessments were confirmed to strongly predict overall survival outcomes in patients with metastatic breast cancer, when performed at a median of 29 days following treatment initiation.

December 8, 2020 - Oncologists widely under-recognize substantial symptoms in patients with breast cancer receiving radiotherapy after undergoing a lumpectomy, highlighting a need to improve symptom detection.

The addition of chemotherapy to endocrine therapy led to an improvement in 5-year invasive disease-free survival and overall survival in premenopausal but not postmenopausal women with hormone receptor–positive, HER2-negative, lymph node–positive breast cancer and a recurrence score between 0 and 25.

December 9, 2020 - The combination of abemaciclib and standard endocrine therapy showed a 28.7% reduction in the risk of invasive disease recurrence or death compared with endocrine therapy alone in patients with high-risk, early hormone receptor–positive, HER2-negative breast cancer.

Hope S. Rugo, MD, FASCO, discusses the updated findings of the SOPHIA trial in HER2-positive metastatic breast cancer.

Rashmi K. Murthy, MD, MBE, discusses the findings of the HER2CLIMB trial in heavily pretreated patients with unresectable locally advanced or metastatic HER2-positive breast cancer.

Martine J. Piccart, MD, PhD, discusses the 6-year follow-up of the APHINITY trial and its impact on the breast cancer field.

In the first 11 months following the FDA approval of the CDK4/6 inhibitor abemaciclib as a single agent and in combination with endocrine therapy for the treatment of hormone receptor-positive, HER2-negative metastatic breast cancer, it is being used heterogeneously, including in patients with characteristics indicative of worse prognosis.

A high absolute lymphocyte count at baseline appears to be an independent predictor for longer overall survival in patients with metastatic breast cancer who are treated with eribulin mesylate.

Mathematical modeling was unable to harmonize the VENTANA SP263 and Dako 22C3 PD-L1 assays with the FDA-approved VENTANA PD-L1 SP142 companion diagnostic for the selection of patients with advanced triple-negative breast cancer appropriate for atezolizumab plus nab-paclitaxel.

Patients with premenopausal breast cancer and discordant clinical and genomic risk had a small increase in distant metastasis if they did not receive adjuvant chemotherapy, according to a post hoc analysis of the MINDACT trial.

Hope S. Rugo, MD, discusses the updated data from the phase III SOPHIA trial for patients with HER2-positive metastatic breast cancer who had received prior anti-HER2 therapies, presented at the 2019 San Antonio Breast Cancer Symposium.

Adding the PARP inhibitor olaparib to neoadjuvant platinum based-chemotherapy was determined to be a safe treatment for patients with triple-negative breast cancer, as well as for patients with breast cancer whose tumors harbor germline BRCA mutations.

Almost half of patients with high-risk luminal-B breast cancer converted to a low risk of recurrence following chemotherapy-free neoadjuvant therapy, matching the performance of standard chemotherapy in small randomized trial.
