Purpose: Quality of life (QOL) is among the most important outcomes for women with metastatic breast cancer (MBC), and it predicts survival. QOL is negatively impacted by cognitive impairment, fatigue, and weight gain. We assessed whether a whole food, plant-based (WFPB) diet-promoting weight loss is feasible and might improve QOL.

Purpose: Breast cancer treatment is associated with weight gain, and obesity and its related cardiometabolic and hormonal risk factors have been associated with poorer outcomes. Dietary intervention may address these risk factors, but limited research has been done in the setting of metastatic breast cancer requiring systemic therapy.

Methods: Women with metastatic breast cancer on stable treatment were randomized 2:1 to an 8-week intervention (n = 21) or control (n = 11).

Article Synopsis
  • The study investigated the impact of a whole food, plant-based (WFPB) diet on weight and health markers in women with metastatic breast cancer undergoing treatment, as weight gain can negatively affect outcomes.
  • Participants were randomized to either an 8-week intervention with dietary support or a control group, with assessments of various health metrics at the start and after 4 and 8 weeks.
  • Results showed significant weight loss and improvements in insulin resistance and cholesterol levels in the WFPB group, suggesting dietary changes could benefit patients, although cancer progression markers remained largely unchanged, indicating more research is needed.

Background: Implementation science is defined as the scientific study of methods and strategies that facilitate the uptake of evidence-based practice into regular use by practitioners. Failure of implementation is more common in resource-limited settings and may contribute to health disparities between rural and urban communities. In this pre-implementation study, we aimed to (1) evaluate barriers and facilitators for implementation of guideline-concordant healthcare services for cancer patients in rural communities in Upstate New York and (2) identify key strategies for successful implementation of cancer services and supportive programs in resource-poor settings.

Introduction: Multigene genomic profiling has become the standard of care in the clinical risk-assessment and risk-stratification of ER, HER2 breast cancer (BC) patients, with Oncotype DX (ODX) emerging as the genomic profile test with the most support from the international community. The current state of the health care economy demands that cost-efficiency and access to testing must be considered when evaluating the clinical utility of multigene profile tests such as ODX. Several studies have suggested that certain lower risk patients can be identified more cost-efficiently than simply reflexing all ER, HER2 BC patients to ODX testing.

Cancer-related fatigue is a common, burdensome symptom of cancer and a side-effect of chemotherapy. While a Mediterranean Diet (MedDiet) promotes energy metabolism and overall health, its effects on cancer-related fatigue remain unknown. In a randomized controlled trial, we evaluated a rigorous MedDiet intervention for feasibility and safety as well as preliminary effects on cancer-related fatigue and metabolism compared to usual care.

Purpose: To quantify the relationship between diabetes and fatigue from pre-chemotherapy to 6 months post-chemotherapy for women with breast cancer compared to women without a history of cancer (controls).

Methods: This was a secondary analysis from a nationwide prospective longitudinal study of female patients with breast cancer undergoing chemotherapy and controls. Diabetes diagnosis (yes/no) was obtained at baseline, and cancer-related fatigue was measured using the Multidimensional Fatigue Symptom Inventory (MFSI) pre-, post-, and 6 months post-chemotherapy in patients; controls were assessed at equivalent time points.

Introduction: A decrease in relative-dose intensity (RDI) of chemotherapy has been shown to be associated with poor patient outcomes in solid tumors and non-Hodgkin's lymphoma. The actual delivered chemotherapy dose received by patients can be influenced by dose reductions and treatment delays, often due to toxicities, most commonly chemotherapy-induced neutropenia (CIN).

Areas Covered: We review seminal evidence and more recent studies that have shown an association between higher RDI and improved patient survival.

Article Synopsis
  • A systematic review analyzed 60 studies to assess the safety and efficacy of dosing strategies for obese cancer patients, concluding that they can tolerate full doses just like non-obese patients.
  • The recommendations include using full weight-based doses for chemotherapy, immunotherapy, and targeted therapies in obese patients while suggesting that dose adjustments for side effects should be similar to those for non-obese patients; further research on body composition effects is also encouraged.

Background: Male patients with breast cancer (BrC) have increased risk of developing 2nd-primary BrC (2nd-BrC). Given the relative rarity of male BrC, population-based registries are needed to analyze overall survival (OS) outcomes for these patients.

Methods: Using the Surveillance, Epidemiology and End Results registry of patients diagnosed from 1975 to 2016, a cohort study of men whose only malignancy was BrC (BrC-O;  = 6,475), and men who developed 2nd-BrC after initial BrC diagnosis (BrC-2;  = 85) was performed.

The skyrocketing cost of health-care demands that we question when to use multigene assay testing in the planning of treatment for breast cancer patients. A previously published algorithmic model gave recommendations for which cases to send out for Oncotype DX (ODX) testing. This study is a multi-institutional validation of that algorithmic model in 620 additional estrogen receptor positive breast cancer cases, with outcome data on 310 cases, named in this study as the Rochester Modified Magee algorithm (RoMMa).

Purpose: Research by our group has shown that acupressure bands are efficacious in reducing chemotherapy-induced nausea (CIN) for breast cancer patients who expect nausea, and that their effectiveness in controlling CIN can largely be accounted for by patients' expectations of efficacy, i.e., a placebo effect.

Background: Cancer-related cognitive impairment (CRCI) is often related to chemotherapy. Increased chronic inflammation is believed to play a key role in the development of CRCI related to chemotherapy but studies assessing this hypothesis specifically in patients receiving chemotherapy are rare.

Methods: We assessed several cognitive domains using the Cambridge Neuropsychological Test Automated Battery (CANTAB) in twenty-two breast cancer patients currently receiving chemotherapy.

Purpose: Fatigue is a prevalent, distressing side effect of cancer and cancer treatment which commonly coexists with insomnia. Cognitive behavioral therapy for insomnia (CBT-I) has been shown to improve insomnia in cancer patients, but less is known about its ability to impact fatigue. This work is the analysis for a secondary aim of a four-arm randomized controlled trial (RCT) study assessing the combined and comparative effect of CBT-I and a wakefulness-promoting agent, armodafinil (A), to improve sleep and daytime functioning in cancer survivors.

Oncotype DX (Genomic Health, Redwood City, CA, USA, current list price $4,350.00) is a multigene quantitative reverse transcription-polymerase chain reaction-based assay that estimates the risk of distant recurrence and predicts chemotherapy benefit for patients with estrogen receptor (ER)-positive breast cancers. Studies have suggested that standard histologic variables can provide similar information.

Purpose: Insomnia is a distressing and often persisting consequence of cancer. Although cognitive behavioral therapy for insomnia (CBT-I) is the treatment of choice in the general population, the use of CBT-I in patients with cancer is complicated, because it can result in transient but substantial increases in daytime sleepiness. In this study, we evaluated whether CBT-I, in combination with the wakefulness-promoting agent armodafinil (A), results in better insomnia treatment outcomes in cancer survivors than CBT-I alone.

Aims: Historically, nuclear staining of ≥10% of invasive tumour cells has been used for oestrogen receptor (ER) positivity. In 2010, ASCO/CAP guidelines recommended the cut-off value be changed to nuclear staining of ≥1%. This study will analyse the relationships between levels of ER expression and clinicopathological features and clinical outcomes, with an emphasis on the ER 1-10% subgroup.

Treatments for breast cancer produce a host of side effects, which can become debilitating. Some cancer treatment-related side effects occur in up to 90% of patients during treatment and can persist for months or years after treatment has ended. As the number of breast cancer survivors steadily increases, the need for cancer control intervention research to alleviate side effects also grows.
