Lifestyle Behaviors and Needs After Breast Cancer Diagnosis: A Qualitative Assessment.

Purpose: There is a need to gain a deeper understanding of facilitators and barriers involving lifestyle behaviors among newly diagnosed breast cancer patients. Design: Research team explored influences (e.g.

Support Through Remote Observation and Nutrition Guidance (STRONG), a digital health intervention to reduce malnutrition among pancreatic cancer patients: A study protocol for a pilot randomized controlled trial.

Background: Malnutrition is a common and distressing condition among pancreatic cancer patients. Fewer than a quarter of pancreatic cancer patients receive medical nutrition therapy (MNT), important for improving nutritional status, weight maintenance, quality of life and survival. System, provider, and patient level barriers limit access to MNT.

Survivors Overcoming and Achieving Resiliency (SOAR): Mindful Eating Practice for Breast Cancer Survivors in a Virtual Teaching Kitchen.

The practice of mindful eating brings awareness to food choices, brings attention to the eating experience, and encourages selecting and preparing food that is both satisfying and nourishing. We examined mindful eating in breast cancer survivors following a 9-week, multidisciplinary virtual teaching kitchen intervention called Survivors Overcoming and Achieving Resiliency (SOAR). SOAR engaged participants through weekly cooking classes that also taught multiple domains of mindfulness.

Results of a randomized phase I dose-finding trial of several doses of isoflavones in men with localized prostate cancer: administration prior to radical prostatectomy.

The purpose of this phase I dose-finding randomized controlled trial was to evaluate the safe and effective dose of isoflavones to be used in future clinical trials for prostate cancer prevention. Forty-five eligible men were supplemented with 40, 60, and 80 mg of purified isoflavones or no supplement from biopsy to prostatectomy. Compliance with the study agent, toxicity, and changes in plasma isoflavones, serum steroid hormones, prostate-specific antigen (PSA), and tissue Ki-67 were analyzed from baseline to completion of the study.

Results of a Randomized Clinical Trial of the Action of Several Doses of Lycopene in Localized Prostate Cancer: Administration Prior to Radical Prostatectomy.

PURPOSE: The purpose of this Phase II randomized-controlled trial was to evaluate the safety and effect of administering several doses of lycopene to men with clinically localized prostate cancer, on intermediate endpoint biomarkers implicated in prostate carcinogenesis. METHODS: Forty-five eligible men with clinically localized prostate cancer were supplemented with 15, 30 or 45 mg of lycopene or no supplement from biopsy to prostatectomy. Compliance to study agent, toxicity, changes in plasma lycopene, serum steroid hormones, PSA and tissue Ki-67 were analyzed from baseline to completion of intervention.

Safety of purified isoflavones in men with clinically localized prostate cancer.

Our purpose was to evaluate the safety of 80 mg of purified isoflavones administered to men with early stage prostate cancer. A total of 53 men with clinically localized prostate cancer, Gleason score of 6 or below, were supplemented with 80 mg purified isoflavones or placebo for 12 wk administered in 2 divided doses of 40 mg to provide a continuous dose of isoflavones. Compliance, changes in plasma isoflavones, and clinical toxicity were analyzed at baseline, 4, and 12 wk.

A Phase II randomized, placebo-controlled clinical trial of purified isoflavones in modulating steroid hormones in men diagnosed with localized prostate cancer.

Our purpose was to evaluate the safety and effectiveness of purified isoflavones in producing an increase in plasma isoflavones and a corresponding change in serum sex hormone binding globulin (SHBG) and steroid hormone levels in men diagnosed with early stage prostate cancer. In this Phase II randomized, double-blinded, placebo-controlled trial, 53 prostate cancer patients with a Gleason score of 6 or below were supplemented with 80 mg purified isoflavones or placebo for 12 weeks. Changes in plasma isoflavones, serum steroid hormones, and safety markers were analyzed from baseline to 12 wk.

A case-control study evaluating the association of purposeful physical activity, body fat distribution, and steroid hormones on premenopausal breast cancer risk.

The objective of this case-control study was to investigate the relationship between purposeful physical activity, body fat distribution, body mass index, and steroid hormones. These factors are known to be implicated in modulating breast cancer risk in premenopausal women. A total of 112 newly diagnosed, premenopausal breast cancer patients and 106 age-matched premenopausal disease-free controls were admitted to the study.

Isoflavones in breast cancer chemoprevention: where do we go from here?

Based on the evidence from epidemiological, animal, in vitro data and human clinical trials, it is evident that isoflavones are promising agents for breast cancer chemoprevention. It is also evident that the form of isoflavone used (purified vs soy products), dose of isoflavone used (low vs high), timing and duration of exposure of isoflavones appears to play a major role in determining agonistic or antagonistic effects. Collectively, these isoflavones have enough evidence to warrant use in a number of clinical trials to examine its efficacy as a potential chemopreventive agent for breast cancer.

The specific role of isoflavones in reducing prostate cancer risk.

Aims: To evaluate the effectiveness of supplementing a group of early stage prostate cancer patients, with 60 mg of soy isoflavones in producing a change in hormonal and proliferative risk parameters that are implicated in prostate cancer promotion.

Methods: Seventy six eligible prostate cancer patients with a Gleason score of 6 or below, between ages 50 and 80 were admitted and supplemented with soy isoflavones or placebo for a 12 week period and changes in PSA and steroid hormones were analyzed at baseline and post intervention.

Results: Fifty-nine patients completed the 12-week intervention.

Fatigue, weight gain, lethargy and amenorrhea in breast cancer patients on chemotherapy: is subclinical hypothyroidism the culprit?

Background: The purpose of this study was to prospectively observe the relative contribution of each viable mechanism such as hyperphagia, physical activity, body composition, steroid hormonal and thyroid function, fatigue scores on changes in body weight in breast cancer patients, receiving adjuvant chemotherapy.

Methods: This was a prospective observational research design where 198 consecutive breast cancer patients receiving adjuvant chemotherapy were monitored from start to end and 6 months post-therapy on changes in anthropometics, fatigue, nutritional intake, physical activity, thyroid and steroid hormones.

Results: We observed a weight gain over >5 lb in 22.

Use of complementary/integrative nutritional therapies during cancer treatment: implications in clinical practice.

Background: The objectives of this study were to determine the prevalence and characterize the use of complementary/integrative nutritional therapies (CINTs) by patients during cancer treatment.

Methods: This retrospective review used data collected as a part of standard clinical care provided by the registered clinical dietitians and included nutritional history, demographic variables, anthropometrics, prevalence of use, and the specific integrative nutritional therapies used by these patients during cancer treatment.

Results: Twenty-nine percent of 820 patients reported use of CINTs not prescribed by their physician.

The specific role of isoflavones on estrogen metabolism in premenopausal women.

Background: There is increasing evidence that dietary factors may play a role in the production, metabolism, and bioavailability of sex hormones and their impact on target tissues. The specific objective of this study was to evaluate the effectiveness of supplementing a group of premenopausal women who were free of breast carcinoma with a dietary supplement of isoflavones (40 mg per day) in producing a change in steroid hormones and menstrual cycle length.

Methods: Sixty-eight consecutively recruited, premenopausal, omnivorous women of all races and ethnicities between the ages of 25 years and 55 years were admitted to the study and randomized to an experimental group supplemented with soy (40 mg genistein per day) or to a control group that consumed a placebo for a 12-week period.
