Brief summary

The purpose of this trial is to determine that sort term calorie restriction will affect tumor biology in biopsy proven breast, endometrial or prostate cancers, which will positively impact biomarkers including miR-21, an onco-miR known to impact cancer outcomes.

Detailed description

PRIMARY OBJECTIVES: 1\) Investigate if caloric restriction will change serum micro ribonucleic acid (RNA) 21 (miR-21) expression in patients with prostate, endometrial or breast cancer. SECONDARY OBJECTIVES: 1. Investigate measurable changes induced by caloric restriction on both patient (host) and tumor characteristics from caloric restriction. 2. Investigate the adherence of the patient to the diet. 4\) Weight, height, and body composition will be assessed via BodyMetrix. BodyMetrix uses ultrasound technology to measure subcutaneous fat. 5\) Patients will have psycho-social evaluation using the Functional Assessment of Cancer Therapy-Prostate (FACT-P) test (prostate cancer), FACT-Breast (B) test (breast cancer), or the FACT-Endometrial Cancer (En) test (endometrial cancer) and the Patient Reported Outcomes Measurement Information System (PROMIS) cancer fatigue short form at baseline, midway through diet, and at the conclusion of the diet. 6\) Patient's nutritional status (Mini Nutritional Assessment \[MNA\] form) will be assessed, and their caloric needs will be calculated. 7\) Local recurrence, progression free survival, distant metastases and overall survival will be assessed.

Inclusion criteria

1. Histological documentation of cancer of the endometrium, prostate or breast. 2. Candidate for definitive cancer surgery as determined by treating physician 3. The ability for the definitive cancer surgery to be scheduled within 4-12 weeks post initiation of dietary intervention as determined by the enrolling physician (not from diagnosis - but from start of diet). 4. No other malignancy within the past 6 months unless it was a non-melanomatous skin lesion 5. BMI ≥21 6. ECOG Performance Status of 2 or less 7. Patient must not be on anti-retrovirals since they may alter patient metabolism

Exclusion criteria

1. Patient is not a candidate for definitive cancer surgery 2. Definitive cancer surgery can not be performed within 4-12 weeks post study enrollment as determined by the enrolling physician. 3. Body Mass Index \< 21 4. Another malignancy within the past 6 months that was not a non-melanomatous skin lesion 5. ECOG Performance Status \>2 6. Patient on anti-retrovirals since they may alter patient metabolism

Design outcomes

Primary

MeasureTime frameDescription
Change in miR-21 expression assessed in serumBaseline up to 12 weeksWill be evaluated by a two-sided paired t-test at significance level 0.05.

Secondary

MeasureTime frameDescription
Overall adherence with diet intervention defined as 90% of all logged events meeting the diet restriction targetUp to 12 weeks
Change in body composition, assessed via BodyMetrixBaseline up to 12 weeksWill be analyzed via a paired t-test.
Change in prostate tumor gene expressionBaseline up to 12 weeks
Change in weight, defined as a percent changeBaseline up to 12 weeksWill be assessed by modeling BMI as a function of time via mixed-effects regression.
Change in temperatureBaseline up to 12 weeksWill be assessed as a function of time via mixed-effects regression.
Change in genomic expression of microRNA 21 (miR-21)Baseline to after definitive surgeryInitial cancer biopsy specimen for genomic analysis will be comped to definitive surgical specimens.
Change in insulinBaseline up to 12 weeksWill be assessed as a function of time via mixed-effects regression.
Change in biome analysis assessed by rectal swabBaseline to 12 weeks
Change in psycho-social outcomes, assessed by the FACT-BBaseline up to 12 weeksWill be assessed as a function of time via mixed-effects regression.
Changes in nutritional status assessed by a Mini Nutritional Assessment (MNA)Baseline up to 12 weeksWill be assessed as a function of time via mixed-effects regression.
Change in weight, defined by body mass index as weight in kg divided by height in meters squaredBaseline up to 12 weeksWill be assessed by modeling BMI as a function of time via mixed-effects regression.
Distant metastases, assessed through patient recordsFrom the date of study enrollment to time of event, assessed up to 12 weeksWill be analyzed via survival methods, specifically the Kaplan-Meier method and the log-rank test. If sufficient events occur, may assess the impact of various patient and clinical/treatment variables on these outcomes via Cox proportional hazards regression. Will be assessed and compared with historic controls using the Kaplan Meier method.
Progression free survival, assessed through patient recordsFrom the date of study enrollment to time of event, assessed up to 12 weeksWill be analyzed via survival methods, specifically the Kaplan-Meier method and the log-rank test. If sufficient events occur, may assess the impact of various patient and clinical/treatment variables on these outcomes via Cox proportional hazards regression. Will be assessed and compared with historic controls using the Kaplan Meier method.
Overall survival, assessed through patient recordsFrom the date of study enrollment to time of event, assessed up to 12 weeksWill be analyzed via survival methods, specifically the Kaplan-Meier method and the log-rank test. If sufficient events occur, may assess the impact of various patient and clinical/treatment variables on these outcomes via Cox proportional hazards regression. Will be assessed and compared with historic controls using the Kaplan Meier method.
Change in blood pressureBaseline up to 12 weeksWill be assessed as a function of time via mixed-effects regression.
Change in heart rateBaseline up to 12 weeksWill be assessed as a function of time via mixed-effects regression.
Change in respiratory rateBaseline up to 12 weeksWill be assessed as a function of time via mixed-effects regression.
Change in psycho-social outcomes, assessed by the FACT-PBaseline up to 12 weeksWill be assessed as a function of time via mixed-effects regression.
Change in psycho-social outcomes, assessed by the FACT-EnBaseline up to 12 weeksWill be assessed as a function of time via mixed-effects regression.
Change in psycho-social outcomes, assessed by the POMIS cancer fatigue short formBaseline up to 12 weeksWill be assessed as a function of time via mixed-effects regression.
Local recurrence, assessed through patient recordsFrom the date of study enrollment to time of event, assessed up to 12 weeksWill be analyzed via survival methods, specifically the Kaplan-Meier method and the log-rank test. If sufficient events occur, may assess the impact of various patient and clinical/treatment variables on these outcomes via Cox proportional hazards regression.
