Brief summary

The aim of this study is to increase, by DHA-induced chemosensitization, the activity of anticancer chemotherapy in patients with a metastatic advanced breast cancer, by a nutritional approach with marin-derived PolyUnsaturated Fatty Acids (PUFA).

Detailed description

Local relapses and metastases make breast cancer a deadly disease. A major goal remains the improvement of treatment efficacy, meaning increasing toxicity to tumor tissue, without additional toxicity to non-tumor tissues. The literature indicates that DHA sensitizes breast malignant tumors, but not non-tumor tissues, to chemotherapy and to radiotherapy through a variety of mechanisms. DHA enrichment of tissues can be achieved through a dietary supplementation of DHA-containing oils, such as fish oil, both in experimental animal models or in humans. Therefore, this represents an original nutritional approach to increase the activity of anticancer treatments through an enhanced specificity toward tumor tissues.

Interventions

DIETARY_SUPPLEMENTDietary supplementation with fish oil.

Patients randomized in this arm will take 3 cans/day with fish oil : DHA is 1.56 g/d and EPA is 2.64 g/d.

DIETARY_SUPPLEMENTDietary supplementation with vegetable oil

Patients randomized in this arm will take 3 cans/day with vegetable oil : no DHA no EPA.

Design outcomes

Primary

MeasureTime frameDescription
Progression Free Survival (PFS)4 monthsPFS is defined as time from randomization to disease progression or death.

Secondary

MeasureTime frameDescription
Overall Survival (OS)3 years after last chemotherapy in studyOS is defined as time from randomization to death due to any cause.
Time To Progression (TTP)First progressionTTP is defined as time from randomization to first documentation of objective tumor progression according to Response Evaluation Criteria in Solid Tumors (RECIST version 1.1).
Safety ans tolerance of dietary supplementation/chemotherapy association4 monthsIncidence and severity of adverse events will be assessed using the NCI Common Terminology Criteria for Adverse Events (CTCAE) Version 4.0.
Dietary supplementation compliance4 monthsCompliance will be assessed through patient's diary.
Objective Response Rate (ORR)The objective response is the best objective response observed from the start of treatment to progression.ORR will be evaluated according to Response Evaluation Criteria in Solid Tumors (RECIST version 1.1).
Pain evaluation4 monthsPain will be assessed by a Visual Analog Scale (VAS) and analgesic consumption.
DHA plasma levelBefore dietary supplementation (at C1), and after 4 months of dietary supplementation.Plasma phospholipids DHA incorporation will be measured with a blood sample.
Neuropathy evaluation4 monthsNeuropathy will be assessed using the NCI Common Terminology Criteria for Adverse Events (CTCAE) Version 4.0.
Quality Of Life (QOL)At C1, after 4 months of chemotherapy, and at the end of chemotherapy.QOL will be assessed by QLQ-C30 and BR23 questionnaires.
