There are currently no practice guidelines available for genetic counseling using telehealth modalities. This evidence-based practice guideline was developed in response to increasing use of alternative service delivery models for genetic counseling, specifically telephone and video-based genetic counseling (telehealth genetic counseling or THGC). A recent systematic evidence review (SER) compared outcomes of THGC with in-person genetic counseling and found that for the majority of studied outcomes, THGC was a non-inferior and comparable service delivery model.

Purpose: The classification of germline variants may differ between labs and change over time. We apply a variant harmonization tool, Ask2Me VarHarmonizer, to map variants to ClinVar and identify discordant variant classifications in a large multipractice variant dataset.

Methods: A total of 7496 variants sequenced between 1996 and 2019 were collected from 11 clinical practices.

Purpose: Oncology care reimbursement has been shifting from a traditional fee-for-service model to either 1- or 2-sided risk models during the past 5 years. A major expense associated with the total cost of care is hospitalization cost. The study set out to investigate whether the creation of an Advanced Community Care Model (ACCM) of home health care would affect 60-day hospitalization and 30-rehospitalization rates in a community oncology setting.

Background: As panel testing becomes more common in clinical practice, it is important to understand the prevalence and trends associated with the pathogenic variants (PVs) identified. This is especially true for genetically heterogeneous cancers, such as breast cancer (BC), in which PVs in different genes may be associated with various risks and cancer subtypes. The authors evaluated the outcomes of genetic testing among women who had a personal history of BC.

Background: This study assessed BRCA1 and BRCA2 mutation prevalence in an unselected cohort of patients with triple-negative breast cancer (BC).

Methods: One hundred ninety-nine patients were enrolled. Triple negativity was defined as <1% estrogen and progesterone staining by immunohistochemistry and HER-2/neu not overexpressed by fluorescence in situ hybridization.

Article Synopsis
  • The study compared disease-free survival (DFS) in high-risk breast cancer patients treated with two different adjuvant therapy regimens.
  • A total of 1,801 patients were included, with similar 6-year DFS rates of 79%-80% for both treatment arms, though arm 2 showed a higher overall survival rate of 87%.
  • The AP-WP regimen (arm 2) was found to be an effective and tolerable alternative to AC-P (arm 1), with differences in toxicity profiles noted between the two groups.

Purpose: We previously reported that four cycles of docetaxel/cyclophosphamide (TC) produced superior disease-free survival (DFS) compared with four cycles of doxorubicin/cyclophosphamide (AC) in early breast cancer. Older women are under-represented in adjuvant chemotherapy trials. In our trial 16% of patients were > or = 65 years.

Purpose: The combination of doxorubicin and cyclophosphamide (AC) is a standard adjuvant chemotherapy regimen. Studies of docetaxel and cyclophosphamide (TC) in metastatic breast cancer (MBC) showed promise in MBC. In 1997, we initiated a randomized adjuvant trial of TC compared with standard-dose AC with a primary end point of disease-free survival (DFS).
