简要总结
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.
详细描述
PRIMARY OBJECTIVES:
- 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:
- Investigate measurable changes induced by caloric restriction on both patient (host) and tumor characteristics from caloric restriction.
- Investigate the adherence of the patient to the diet.
- Weight, height, and body composition will be assessed via BodyMetrix. BodyMetrix uses ultrasound technology to measure subcutaneous fat.

入选标准
- •Histological documentation of cancer of the endometrium, prostate or breast.
- •Candidate for definitive cancer surgery as determined by treating physician
- •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).
- •No other malignancy within the past 6 months unless it was a non-melanomatous skin lesion
- •ECOG Performance Status of 2 or less
- •Patient must not be on anti-retrovirals since they may alter patient metabolism
排除标准
- •Patient is not a candidate for definitive cancer surgery
- •Definitive cancer surgery can not be performed within 4-12 weeks post study enrollment as determined by the enrolling physician.
- •Body Mass Index < 21
- •Another malignancy within the past 6 months that was not a non-melanomatous skin lesion
- •ECOG Performance Status >2
- •Patient on anti-retrovirals since they may alter patient metabolism
