I-III 期乳腺癌超重/肥胖患者减肥的胰腺营养计划

2026年9月28日 更新者：City of Hope Medical Center

胰腺营养计划 (PNP)：超重/肥胖乳腺癌幸存者的新型减肥计划

This pilot clinical trial studies a pancreatic nutritional program for helping patients with stage I-III breast cancer who are overweight or obese lose weight. When patients have a high level of sugar in their blood, due to eating sugary foods and/or a sedentary lifestyle, the pancreas needs to work harder to digest the sugar. This can cause weight gain, obesity, and other illnesses. Breast cancer patients who are overweight and obese are more likely to have their breast cancer return. The pancreatic nutritional program is a diet and lifestyle intervention that helps protect the pancreas by keeping blood sugar levels low, and may help patients achieve sustained weight loss, improved health, better quality of life, and possibly a better outcome to their treatment.

详细说明

PRIMARY OBJECTIVES:

I. To estimate the change in body weight at 6 months post-intervention relative to baseline.

SECONDARY OBJECTIVES:

I. To examine changes in: body composition; body chemistry; physical fitness; inflammatory markers; deoxyribonucleic acid (DNA) repair capacity; and quality of life per the Functional Assessment of Cancer Therapy - Breast (FACT-B)+4, version 4 questionnaire at 6 months post-intervention relative to baseline.

II. To describe adverse events possibly related to wearing the glucometer sensor or following the pancreatic nutritional program (PNP) diet.

III. To document compliance with the various components of the PNP (wearing the glucometer sensor; recording body weight; completing journal entries; completing meal cards; attending weekly counseling sessions with diet instructor).

OUTLINE:

Patients participate in the PNP intervention, which begins with a baseline meeting with a diet and lifestyle instructor to discuss baseline testing results, begin an educational plan, determine an individualized eating plan, and print out food choices. Patients also undergo automated glucometry every 15 minutes, review their individual food choices and blood glucose levels 90 minutes after eating, keep a daily nutrition and lifestyle journal log, fill out a daily meal discovery card log, and attend weekly meetings with a diet and lifestyle instructor for 12 weeks.

After completion of study, patients are followed up within 1 week and then at 6 months.
