Further study details as provided by Hanno Pijl, Leiden University Medical Center:

Primary Outcome Measures:
  • chemotherapy-induced neutropenia [ Time Frame: approximately 126 days ]
    Neutrophil count after 6 cycles of chemotherapy (6x 21 days)


Secondary Outcome Measures:
  • chemotherapy-induced DNA damage in leukocytes [ Time Frame: 21 days ]
    chemotherapy-induced DNA damage in leukocytes will be determined after each cycle of chemotherapy (i.e. every 21 days)

  • perceived side effects of chemotherapy [ Time Frame: 21 days ]
    To determine the effect of short-term fasting on perceived side effects after each cycle of chemotherapy (i.e. every 21 days)

  • effect of short-term fasting on the body's inflammatory response to chemotherapy [ Time Frame: 21 days ]
    To determine the effect of short-term fasting on the body's inflammatory response to chemotherapy, inflammation parameters will be measured after each cycle of chemotherapy


Enrollment: 13
Study Start Date: March 2011
Study Completion Date: January 2015
Primary Completion Date: April 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Short-term fasting
short term fasting (i.e. 24 hours before and 24 hours after administration of chemotherapy) in 20 breast cancer patients
Other: Short-term fasting
Short-term fasting, i.e. 24 hours before and 24 hours after administration of chemotherapy
Placebo Comparator: Healthy nutrition
20 breast cancer patients eat according to the current guidelines for healthy nutrition as from 24 hours before until 24 hours after the beginning of administration of chemotherapy.
Other: Healthy nutrition
Eating according to the current guidelines for healthy nutrition as from 24 hours before until 24 hours after the beginning of administration of chemotherapy. Dietary instructions will be given by a dietician and actual food intake will be recorded in a journal.

Detailed Description:
Evidence from experimental animals provides strong support for the concept that caloric restriction (CR) increases resistance to multiple forms of stress. CR decreases plasma levels of growth factors, e.g. insulin-like growth factor-I (IGF-I), thereby diverting energy from growth to maintenance. Accordingly, the currently available information suggests that short-term fasting protects normal cells against the perils of (high dose) chemotherapy. In contrast, cancer cells are not (or less) protected as a result of their self-sufficiency in growth signals. This phenomenon is termed Differential Stress Resistance (DSR). DSR reduces the severity of side-effects caused by the toxicity of chemotherapy, without interfering with its effect on reduction of tumour volume or tumour markers. A recent report, sketching a case series of 10 cancer patients, suggests that short term fasting protects against the side effects of chemotherapy in humans. Indeed, the majority of patients preferred fasting over feeding in preparation of their therapy. This study aims to further evaluate the impact of fasting on tolerance to chemotherapy in humans.
