Plain language summary
Pancreatic cancer is commonly associated with poor prognosis and low overall five-year survival rate (5–7%) due to the early metastatic potential of pancreatic cancer cells. Strategies to improve the health outcomes in pancreatic cancer are challenging. The aims of this study where to investigate: - whether plasma metabolites, isolated after a 28-day intervention, would reduce migration of two pancreatic cancer cell lines (PANC-1 and AsPC-1); - whether expression of adhesion molecules on cancer and endothelial cells were influenced by plasma anthocyanins (ACN) metabolites; - which molecular mechanisms were involved; and - which metabolites in plasma and urine were altered during a long-term ACN intake and how they associate with the inhibitory effects on migration. This study is a randomised, double-blind, placebo-controlled, cross-over, 28-days intervention - ATTACH study (Anthocyanins Target Tumor cell Adhesion—Cancer vs. Endothelial Cell (HUVEC)). Thirty-five (female n = 27 and male n = 8) young, healthy volunteers participated in the intervention. Results show that ACN and metabolites isolated from plasma after a long-term ACN-rich juice intervention reduced the migration and expression of cell adhesion molecules in PANC-1 cancer cells in vitro through activation of two pathways [focal adhesion kinase- and nuclear factor kappa light chain enhancer of activated B cells (NF-kB)-pathways] as well as the reduction of reactive oxygen species. Authors conclude that their findings can lead to the investigation of interactions of ACNs with classical cancer prevention strategies.
Abstract
Pancreatic cancer is primarily considered to be a metastatic disease with a low 5-year survival rate. We aimed to detect if plasma-isolated anthocyanins and their metabolites (PAMs) modulate pancreatic cancer cells migration and to describe molecular targets of PAMs in this process. Plasma metabolites were isolated by solid-phase extraction before and after a 28-days intervention trial involving 35 healthy subjects comparing effects of a daily anthocyanin-rich juice intake vs. placebo. Plasma extracts were used for migration and mechanistic in vitro studies as well as for metabolomic analysis. Pancreatic PANC-1 and AsPC-1 were used for migration studies in a Boyden chamber co-cultured with endothelial cells. Expression of adhesion molecules on cancer and endothelial cells were determined by flow cytometry and NF-kB (nuclear factor-kappa B) p65 and focal adhesion kinase activation were measured by immunoassays. UHPLC-MS/MS metabolomics was done in plasma and urine samples. Plasma extracts isolated after the intake of the anthocyanin-rich juice significantly reduced PANC-1 migration, but not AsPC-1 migration. In PANC-1, and to a lower extent in endothelial cells, plasma extracts after juice intake decreased the expression of ß1- and ß4-integrins and intercellular adhesion molecule-1. Pooled plasma from volunteers with the highest inhibition of PANC-1 migration (n = 10) induced a reduction of NF-kB-p65 and FAK-phosphorylation in cancer and in endothelial cells. Concerning metabolites, 14 were significantly altered by juice intervention and PANC-1 migration was inversely associated with the increase of o-coumaric acid and peonidin-3-galactoside. PAMs were associated with lower PANC-1 cell migration opening new strategies for metastatic pancreatic cancer treatment.

Breast cancer (BCa) is the most common form of cancer among women. Radiotherapy (RT) treatment is an important component of breast cancer treatment and is used with curative intent as well as for palliation. One commonly reported adverse side effect of RT is cancer related fatigue (CRF). The aims of this study were to (a) examine the effects of a 12-week home-based resistance and aerobic exercise program on CRF, health-related quality of life (HRQoL), and sleep quality and duration in BCa patients during and up to 12 months after RT, and (b) investigate how CRF, HRQoL, and sleep quality and duration affect the participants’ ability to follow their prescribed exercise program. This study was a two-arm, randomised controlled clinical trial. One hundred and six (n = 106) women with stage I-III BCa scheduled to receive radical RT were randomised into exercise (n = 51) or usual care (n = 55). Results show that CRF was present at baseline and persisted during RT. The exercise group had a quicker reduction in CRF compared to the usual care group. Moreover, there was a significant difference in the HRQoL during RT between groups, and a quicker HRQoL improvement post-RT for the exercise group, with no changes in sleep quality or duration. Additionally, less fatigue and less trouble sleeping were associated with greater weekly aerobic exercise duration and higher rating of perceived exertion during aerobic exercise. Authors conclude that home-based exercise during RT is safe and effective in reducing CRF and improving HRQoL
Abstract
BACKGROUND Radiotherapy (RT) can lead to cancer-related fatigue (CRF) and decreased health-related quality of life (HRQoL) in breast cancer patients. The purpose of this trial was to examine the feasibility and efficacy of a home-based resistance and aerobic exercise intervention for reducing CRF and improving HRQoL in breast cancer patients during RT. METHODS Women with breast cancer (N = 106) commencing RT were randomized to 12 weeks of home-based resistance and aerobic exercise (EX) or usual care/control (CON). The primary endpoint was CRF, with secondary endpoints of HRQoL, sleep duration and quality, and physical activity. Measurements were undertaken prior to RT, at completion of RT (~ 6 weeks), at completion of the intervention (12 weeks), and 6 and 12 months after RT completion, while CRF was also measured weekly during RT. RESULTS Eighty-nine women completed the study (EX = 43, CON = 46). Over the 12-week intervention, EX completed 1-2 resistance training sessions and accumulated 30-40 min of aerobic exercise weekly. For CRF, EX had a quicker recovery both during and post-RT compared to CON (p < 0.05). Moreover, there was a significant difference in HRQoL between groups at RT completion, with HRQoL unchanged in CON and higher in EX (p < 0.05). There was no change in sleep duration or quality for either group and there were no exercise-related adverse effects. CONCLUSIONS Home-based resistance and aerobic exercise during RT is safe, feasible, and effective in accelerating CRF recovery and improving HRQoL. Improvements in CRF and HRQoL for these patients can be achieved with smaller exercise dosages than stated in the generic recommendations for breast cancer.

Plain language summary
Androgen deprivation therapy (ADT) forms the cornerstone in the treatment of localised high-risk, locally advanced, and metastatic prostate cancer (PCa). The hypothesis of this study was that protein supplementation augments the benefits of prolonged resistance exercise training to attenuate the decline in muscle mass, reduce fat mass accrual, and increase strength and physical performance in PCa patients on ADT. This study is a multicentre partly randomised controlled trial, comparing two intervention groups with a separately recruited control group. One hundred and twenty-six patients were included, and ninety-six patients finished the study. Results show that 20 week of resistance exercise training was feasible, safe, and well tolerated, and effectively counteracted the negative effect of ADT treatment on body composition, muscle mass, leg strength, and aerobic capacity in men with advanced PCa. Protein supplementation did not further augment the benefits of resistance exercise training. Authors conclude that protein supplementation is not required to further augment gains in muscle mass and strength after resistance exercise training in PCa patients who habitually consume ample protein.
Abstract
PURPOSE This study aimed to assess the effects of 20 wk resistance exercise training with or without protein supplementation on body composition, muscle mass, muscle strength, physical performance, and aerobic capacity in prostate cancer patients receiving androgen deprivation therapy (ADT). METHODS Sixty prostate cancer patients receiving ADT were randomly assigned to perform 20 wk of resistance exercise training with supplementation of 31 g whey protein (EX + PRO, n = 30) or placebo (EX + PLA, n = 30), consumed immediately after exercise and every night before sleep. A separate control group (CON, n = 36) only received usual care. At baseline and after 20 wk, body composition (dual-energy x-ray absorptiometry), muscle mass (computed tomography scan), muscle strength (1-repetition maximum strength tests), physical performance (Timed Up and Go Test, 30-Second Chair Stand Test, and Stair Climb Test), aerobic capacity (cardiopulmonary exercise test), and habitual dietary intake (food diary) were assessed. Data were analyzed using a two-factor repeated-measures ANOVA. RESULTS Over time, muscle mass and strength increased in EX + PRO and EX + PLA and decreased in CON. Total fat mass and fat percentage increased in EX + PRO and CON, but not in EX + PLA. Physical performance did not significantly change over time in either group. Aerobic capacity was maintained in EX + PLA, but it decreased in EX + PRO and CON. Habitual protein intake (without supplements) averaged >1.0 g·kg body weight -1 ·d -1 , with no differences over time or between groups. CONCLUSIONS In prostate cancer patients, resistance exercise training counteracts the adverse effects of ADT on body composition, muscle mass, muscle strength, and aerobic capacity, with no additional benefits of protein supplementation.

Plain language summary
Aromatase inhibitors (AIs) are used as a treatment in breast cancer; however, a side effect of their use is often the development of aromatase inhibitor induced arthralgia (AIA), which manifests as pain in the joints, muscle weakness and reduced grip strength. Subsequently, many individuals stop taking AIs, resulting in poorer disease prognosis. Tart cherries (TC) have been shown in studies to help relieve joint pain and pain associated with exercise and so this RCT aimed to determine the effect of TC consumption on 60 breast cancer patients with AIA. The results showed that after 6-weeks individuals given TC had less pain, with some individuals reporting no pain at all. It was concluded that TC is a reliable and safe option for the management of AIA in breast cancer patients. This study could be used by healthcare professionals to recommend TC as an adjunct to aromatase inhibitor therapy in individuals with breast cancer who are experiencing pain.
Abstract
BACKGROUND Aromatase Inhibitor induced Arthralgia (AIA) can cause noncompliance leading to decreased breast-cancer survival. Effective interventions for AIA are limited. Tart cherry (TC) showed beneficial effect on musculoskeletal pain. 48 patients (Pts) randomized to TC versus placebo over 6 weeks, TC (23pts) had 34.7% mean pain decrease versus 1.4% in Placebo (25pts). TC can improve AIA in nonmetastatic breast-cancer patients. METHODS Randomized, placebo-controlled, double-blind trial. Eligible patients with NMHPBC on AI for at least 4 weeks were randomized to TC concentrate [50 tart cherries] vs. placebo (P) [syrup] in 1:1 model. Patients instructed to consume 1 Oz of concentrate in 8 Oz water daily for 6 weeks, and document their pain intensity at baseline, weekly and at study completion in a diary using Visual Analog Scale (VAS), with 0 mm indicating no pain, and 100 mm indicating highest pain. RESULTS Sixty patients were enrolled. Two patients did not complete the study due to diarrhea, and 10 patients were noncompliant. Forty-eight patients were included in the final analysis. TC group (23 pts) had 34.7% mean decrease in pain compared to 1.4% in P group (25 pts). This difference was statistically significant (Mann-Whitney U Test, P = .034). CONCLUSIONS Tart cherry can significantly improve AIA in nonmetastatic breast cancer patient.

Plain language summary
The occurrence of thyroid cancer has increased in recent years. Part of the treatment for this disease is removal of the thyroid gland and then the administration of radioactive iodine. To help aid the uptake of radioactive iodine, individuals may need to withdraw from their thyroid hormone therapy, known as thyroid hormone withdrawal (THW). This is however accompanied by side effects such as fatigue, constipation, and weight gain, all of which have been hypothesised to be due to gut microbiota dysbiosis. This randomised control trial aimed to determine any gut and oral microbiota signatures in 50 individuals who have undergone THW because of thyroid cancer and to see if probiotics have any beneficial effects. The results showed that gut and oral microbiota diversity was decreased after THW. Upon the administration of probiotics, diversity was restored, energy and blood lipid levels were improved, and weight gain and a dry mouth were alleviated. It was concluded that probiotics reduce the occurrence of side effects following THW, which may be related to the modification of oral and gut microbiota diversity. This study could be used by healthcare professionals to understand that probiotics may be of benefit to improve the side effects associated with THW in individuals with thyroid cancer.
Abstract
BACKGROUND Thyroid hormone withdrawal (THW) in postoperative thyroid cancer patients who need always accompanied by complications (e.g., dyslipidemia and constipation). At present, there are no effective and safe means to alleviate these complications. PURPOSE We aimed to assess the oral-gut microbiota profiles in THW patients then investigate whether probiotics could alleviating alleviate THW related complications and investigate whether these therapeutic effects were associated with the oral-gut microbiota state. METHODS Fifty eligible thyroid carcinoma patients undergoing thyroidectomy were randomly assigned to receive probiotics or placebo during THW. Complications were assessed through validated questionnaires and plasma lipid indicators. The complex probiotics preparation was composed of Bifidobacterium infantis, Lactobacillus acidophilus, Enterococcus faecalis, and Bacillus cereus. RESULTS Probiotics alleviated lack of energy, constipation, weight gain, and dry mouth and decreased the levels of fecal/serum LPS and plasma lipid indicators (total cholesterol, triglycerides, low-density lipoprotein, and apolipoprotein A) (P < 0.05). Gut and oral microbial diversity were significantly decreased after THW, while an increased microbial dysbiosis index (MDI) was observed. Probiotics distinctly restored the gut and oral microbial diversity. Increased Holdemanella, Enterococcus, and Coprococcus_2, while decreased Fusobacterium, Eubacterium_ruminantium_group, Ruminococcus_1, and Parasutterella in the gut were found after probiotics intervention. Lack of energy, constipation, weight gain, and dyslipidemia were seen to be related to the above microbiota. In addition, probiotics reduced oral Prevotella_9, Haemophilus, Fusobacterium, and Lautropia, which were positively correlated with the occurrence of dry mouth. CONCLUSION Probiotics reduce the incidence of complications in patients after THW, which may be related to modifying the oral and gut microbiota.

Plain language summary
Cancer cachexia is a multifactorial condition that reveals impairments in energy and protein balance leading to weight loss through the loss of skeletal muscle and body fat. Nutritional status of cancer patients affects therapeutic efficacy, and the disease survival is influenced by the degree of anorexia. The aim of this study was to evaluate the efficacy of omega-3 fatty acids fortified nutrition supplement intervention on nutritional status, quality of life (QOL) and pro-inflammatory cytokine concentrations of cancer patients. This study was a randomised controlled study. Participants (n = 58) included in the study were patients who were in stages between II to IV receiving one or more cancer therapies without taking any nutritional supplements. Both control and experimental groups received regular nutrition counselling and education, while only the experimental group was asked to take oral nutrition supplements (ONS) twice a day (400 ml, 400 kcal). Results show that ONS intervention: - alleviated symptoms of gastrointestinal symptoms including nausea, vomiting and constipation; - exerted improvements in many of QOL indices; and - did not improve (statistically significant) biochemical markers of nutritional status and concentration level of pro-inflammatory cytokines. Authors conclude that nutritional supplements can improve some of the QOL components which need evidence-based explanation in mechanistic aspects.
Abstract
OBJECTIVE Gastrointestinal (GI) cancer patients often experience severe malnutrition during cancer therapies due to gastrointestinal dysfunctions including poor digestion and absorption as well as tumor-associated anorexia. In this study, we performed a randomized clinical trial to determine the efficacy of oral nutrition supplement (ONS) enriched with omega-3 fatty acids on nutritional status, quality of life (QOL), and pro-inflammatory indices. METHODS Patients diagnosed with GI cancers were recruited and screened for eligibility. A total of 58 patients were randomly allocated to either the control group (n=27) or the experimental group (n=31). The intervention group received 200 ml ONS twice a day while the control group received routine care. Anthropometrics, Patient-Generated Subjective Global Assessment (PG-SGA) score, QOL score and nutrient intake data were collected at baseline, week 4 and week 8. Blood was drawn for biochemical assessments. Nine patients from each group dropped out of the study Forty patients (18 control patients and 22 intervention patients) completed the study. RESULTS This study showed that ONS intervention improved PG-SGA scores in the intervention group (p<0.01). Scores of physical functioning score and role functioning were declined only in the control group and the difference between week 8 and baseline for role functioning was significant (p<0.001). Fatigue score was steadily decreased in the experiment group, and the differences between week 8 and baseline was significant between two groups (p<0.02). However, no statistically significant improvement in biochemical markers of nutritional status and pro-inflammatory cytokine concentrations were found. These results suggests that ONS intervention for 8 weeks improves PG-SGA scores and QOL scores in patients undergoing cancer therapy.

Plain language summary
Aging populations and the increased prevalence of other cancer risk factors have led to an increased incidence of cancer in women globally. Cancer treatments often leave women with a range of residual physical and psychological side effects. Comprehensive cancer rehabilitation can reduce symptom burden and health service utilisation, whilst generally improving health-related quality of life (HRQOL). The primary aim of this study was to test the efficacy of a multimodal, digitised lifestyle intervention on HRQOL of women treated for cancer. This study is a multi-centre, single-blinded, randomised controlled 12-week trial. Fifty-one women previously treated for breast, blood or gynaecological cancer were randomly assigned to either an intervention or usual care arm. Results indicate improvements in many HRQoL domains and in component summary scores. Particularly notable were the improvements in general health and bodily pain, vitality, mental health, and global physical and mental health summary scores among women in the intervention group. Authors conclude that the complex and synergistic effects of many modifiable health behaviours emphasise the need for bundled health behaviour interventions to optimise women’s health and wellbeing after completion of active cancer treatment.
Abstract
BACKGROUND The residual effects of cancer and its treatment can profoundly affect women's quality of life. This paper presents results from a multisite randomized controlled trial that evaluated the clinical benefits of an e-health enabled health promotion intervention (the Women's Wellness after Cancer Program or WWACP) on the health-related quality of life of women recovering from cancer treatment. METHODS Overall, 351 women previously treated for breast, blood or gynaecological cancers were randomly allocated to the intervention (WWACP) or usual care arms. The WWACP comprised a structured 12-week program that included online coaching and an interactive iBook that targeted physical activity, healthy diet, stress and menopause management, sexual wellbeing, smoking cessation, alcohol intake and sleep hygiene. Data were collected via a self-completed electronic survey at baseline (t0), 12 weeks (post-intervention, t1) and 24 weeks (to assess sustained behaviour change, t2). The primary outcome, health-related quality of life (HRQoL), was measured using the Short Form Health Survey (SF-36). RESULTS Following the 12-week lifestyle program, intervention group participants reported statistically significant improvements in general health, bodily pain, vitality, and global physical and mental health scores. Improvements were also noted in the control group across several HRQoL domains, though the magnitude of change was less. CONCLUSIONS The WWACP was associated with improved HRQoL in women previously treated for blood, breast, and gynaecological cancers. Given how the synergy of different lifestyle factors influence health behaviour, interventions accounting for the reciprocity of multiple health behaviours like the WWACP, have real potential for immediate and sustainable change. TRIAL REGISTRATION The protocol for this randomised controlled trial was submitted to the Australian and New Zealand Clinical Trials Registry on 15/07/2014 and approved on 28/07/2014 ( ACTRN12614000800628 ).

Plain language summary
Cancer anorexia–cachexia syndrome (CACS) is usually found in advanced cancer patients. CACS is a multifactorial process which comprises skeletal muscle and adipose tissue loss which may be compounded by anorexia and a dysregulated metabolic state. The hypothesis of this study was that curcumin will increase body compositions and body weight in patients with solid malignancy and CACS when compared to placebo after adjusting by age, gender, primary site of cancer, stage of cancer, performance status, and supplementary nutrition support. This study was a double-blind, placebo-controlled randomised phase lla study. A total of 46 patients were enrolled, of whom 33 underwent 1:1 block of four randomisations. Seventeen patients were randomly assigned to receive curcumin at dose of 800 mg twice daily orally and sixteen patients were randomly assigned to received placebo. Results show that curcumin supplementation: (1) did not statistically significantly improve body compositions and body weight when compared to placebo; (2) may cause clinical benefit in term of hand grip muscle strength and slow progress of CACS by decreasing in basal metabolic rate and preventing the decline in serum albumin; and (3) administered orally for two months at a dose of up to 2 grams daily appeared safe and no serious adverse events were reported. Authors conclude that curcumin inhibited process of CACS via reduction of basal metabolic rate and slowed down the progression of hand-grip muscle strength loss. Furthermore, nuclear factor kappa B [regulator of gene expression] levels merit further exploration as potentially suitable predictive biomarker for CACS treatment with curcumin.
Abstract
OBJECTIVE We aim to investigate the effect of curcumin on preventing cancer anorexia-cachexia syndrome (CACS) via through mechanism of inhibition on NF-kB signal pathway. Outcome measurement for primary end point was improvement of body tissue composition, and the secondary end points were body weight and body mass index, hand grip muscle strengthening, and safety. METHODS This is randomized, double-blind, placebo-controlled phase ll a study, 33 patients with CACS in solid malignancy were enrolled and randomized in 1:1 to receive oral curcumin (at a dose of 800 mg twice daily) or placebo for 8 weeks. RESULTS All parameters of body compositions were not statistically significant different between two groups, which were consist body fat mass [-1.25(SEM 0.87) vs. +0.63(SEM 0.55); p=0.119], skeletal muscle mass [-0.35(SEM 0.60) vs.+0.33(SEM 0.42); p=0.408] and percent body fat [-0.47(SEM 0.95) vs. -0.29(SEM 0.82); p=0.893] including with basal metabolic rate [-13.47(SEM 21.94) vs. +15.30(13.76); p=0.336]. The average of weight loss was also not statistically significant different between two groups. [-1.4 kg(SEM 0.89) in curcumin vs-1.12 kg(SEM 0.73), p=0.810]. Notably, patient with curcumin had less reduction of hand-grip muscle strength on both hands [Rt. handed: -2.47 in curcumin vs. -5.36 in placebo; p=0.318] [Lt. handed: -1.98 vs. -5.43; p=0.317], and basal metabolic rate than placebo group. Most adverse events were grade 1 on both groups similarly. CONCLUSION Curcumin was not shown to be superior to placebo with regard to increasing the body composition in cancer patients with CACS. However, curcumin might show some clinical benefits, including slow progression of hand-grip muscle strength loss, and basal metabolic rate. Further investigations should be explored.

Plain language summary
The use of androgen deprivation therapy (ADT) has coincided with improvements in disease control and improved overall survivorship in many men treated for prostate cancer. Exercise and nutrition interventions during and/or after ADT are strongly recommended to mitigate or improve body composition and reduce cardiometabolic side effects. The aim of this study was to examine the combined effects of a Mediterranean diet (MED-diet) and high intensity interval training (HIIT) on cardiorespiratory fitness, body composition and quality of life, compared to usual care, in men with prostate cancer treated with ADT. This study is a two-arm randomised controlled trial. Participants (n = 23) were randomly allocated to either an intervention or usual care group in a 1:1 ratio. Results show that for men with prostate cancer undergoing ADT, a MED-diet with HIIT compared to usual care at 20 weeks (i) significantly improved cardiorespiratory fitness relative; (ii) reduced body weight; (iii) maintained lean body mass despite achieving weight loss; (iv) significantly improved vitality and mental health composite, and clinical improvements were seen in prostate-cancer specific quality of life and cancer-related fatigue. Authors conclude that future larger-scale trials examining the MED-diet with HIIT on cardiorespiratory fitness, body composition and quality of life would help to extend the findings of their study.
Abstract
Background: Androgen deprivation therapy (ADT) in prostate cancer has been shown to deteriorate body composition (reduced lean mass and increased body and fat mass) and increase the risk of cardiovascular morbidity. The Mediterranean style dietary pattern (MED-diet) and high intensity interval training (HIIT) may synergistically alleviate these side effects and improve quality of life in men treated with ADT. Methods: Twenty-three men (65.9 ± 7.8 years; body mass index: 29.6 ± 2.7 kg/m2; ADT duration: 33.8 ± 35.6 months) receiving ADT for ≥3 months were randomly assigned (1:1) to 20 weeks of usual care or the MED-diet (10 nutrition consults) with HIIT (4 × 4 min 85−95% heart rate peak, 3× week, starting at 12 weeks). Results: The MED-diet with HIIT significantly improved cardiorespiratory fitness (+4.9 mL·kg−1·min, p < 0.001), and body mass (−3.3 kg, p < 0.001) compared to the usual care group at 20 weeks. Clinically meaningful (≥3 points) improvements were seen in quality of life and cancer-related fatigue after 20 weeks. Conclusions: The MED-diet with HIIT increased cardiorespiratory fitness and reduced body weight in men with prostate cancer treated with ADT. Larger trials determining whether the MED-diet with HIIT translates to cardiovascular benefits are warranted.

Plain language summary
Studies focusing on the effect of soy on risk for breast cancer are extensive, however there is very little research assessing its affects in men with prostate cancer. This post-hoc analysis of individuals enrolled in a randomised control trial looking at individuals on a soy protein isolate or milk protein placebo aimed to determine if soy had any effect on prostate cancer. The results showed that both circulating testosterone and its carrier molecule, sex hormone binding globulin (SHBG), were both decreased in individuals consuming the soy protein. All other hormones and measures related to cancer cell death and growth remained unaffected. It was concluded that 18 months of consumption of soy protein isolate reduced circulating testosterone and SHBG but had little effect on other measures related to cancer development. This study could be used by healthcare professionals that a diet high in soy may have limited effect on prostate cancer.
Abstract
Many studies have addressed the effects of dietary supplementation with soy protein on cancer risk and mortality, but there are only few randomized studies with soy in males. We used serum samples from a two-year trial of soy protein isolate supplementation in middle-aged to older males at risk of recurrence of prostate cancer after radical prostatectomy to determine soy effects on steroid hormones involved in prostate cancer (testosterone, SHBG, and estradiol) and explore the effects on biomarkers of the growth hormone/IGF-1 axis, apoptosis, and angiogenesis. Compared with a casein-based placebo, 18 mo, of consumption of 19.2 g/day of whole soy protein isolate containing 24 mg genistein-reduced circulating testosterone and SHBG, but not free testosterone, and did not affect serum concentrations of estradiol, VEGF, IGF-1, IGFBP-3, IGF-1/IGFBP-3 ratio, soluble Fas, Fas-ligand, and sFas/Fas-ligand ratio. Thus, soy protein supplementation for 18 mo, affected the androgen axis, but the effects on other cancer biomarkers remain to be more definitively determined. The study was registered at clinicaltrials.gov (NCT00765479).
